    This study was designed to assess the prevalence, distribution, and patterns of injury among athletes engaged in combat sports and compare the prevalence, pattern, and types of oral and maxillofacial trauma in these athletes. A total of 120 male athletes engaged in four combat sports (boxing, taekwondo, kickboxing, and Muay Thai) who had sustained bodily trauma were studied; 95 subjects with at least one traumatic injury to the face requiring treatment were referred to us by the physician team. The type of injury (facial laceration, facial fractures, jaw dislocation, etc.), site of facial injury (jaw, nose, malar bone, teeth, etc.), dental injuries (tooth fracture, displacement, luxation, and avulsion), causative sport (boxing, taekwondo, kickboxing, and Muay Thai) as well as demographic data were recorded. Injuries were examined clinically and radiographically, and treated accordingly by a specialist. Treatment data and demographics were recorded for each subject. Recorded data were assessed, and χ(2), ANOVA, and Kruskal-Wallis tests were used to statistically analyze and compare the data. Of 120 subjects, 95 male subjects (79.2%), aged 18-25 years (avg. 20 years), had at least one traumatic injury to the face requiring medical treatment. These injuries included facial laceration, bone fractures (nose, mandible, and zygoma), dental injuries (displacement, luxation, fracture, and avulsion), and mandibular dislocation which were recorded in 83 (69.2%), 55 (45.1%), 53 (44.2%), and 8 (6.7%) cases respectively. Statistically significant differences were encountered among various injuries and the sports; kickboxing caused the most maxillofacial injuries and was identified as more injurious. Tooth fractures (59.7%) were the most common dental injuries, and the nose (84.7%) was the most frequently fractured facial bone. Lacerations were more common in Thai-boxers (93.3%). Injuries were significantly greater in professional rather than amateur athletes. In this study

    The course and configuration of typical maxillofacial fractures (type Le Fort I-III) and lateral maxillary fractures including the zygomatic arch were reconstructed in detail by application of barium paste on a bony skull and radiogrpahs in standard projections were performed and evaluated. It was obvious from the resulting radiographs that for most maxillofacial fractures a half axial or Water's view was most helpful. Lateral views only give additional information when there is a considerable degree of dislocation of fragments. Comparison with a prediatric skull of 8 years of age demonstrated that fractures of the zygomatic arch in this age group cannot be demonstrated by the typical submento-vertical view, but are shown on a Towne projection. The radiographic appearance of important maxillofacial fractures is demonstrated. The necessity of further studies in cases where reconstructive surgery appears necessary is discussed and CT rather then conventional tomography is advocated. (orig.) [de

    In this paper, we report a retrospective study of 236 patients with facial bone fractures from various sports who were treated at the Department of Plastic and Reconstructive Surgery, Inha University Hospital, Incheon, South Korea, between February 1996 and April 2007. The medical records of these patients were reviewed and analyzed to determine the clinical characteristics and treatment of the sports-related facial bone fractures. The highest frequency of sports-related facial bone fractures was in the age group 11 to 20 years (40.3%); there was a significant male predominance in all age groups (13.75:1). The most common causes of the injury were soccer (38.1%), baseball (16.1%), basketball (12.7%), martial arts (6.4%), and skiing or snowboarding (11%). Fractures of the nasal bone were the most common in all sports; mandible fractures were common in soccer and martial arts, orbital bone fractures were common in baseball, basketball, and ice sports, and fractures of the zygoma were frequently seen in soccer and martial arts. The main causes of the sports injuries were direct body contact (50.8%), and the most commonly associated soft tissue injuries were found in the head and neck regions (92.3%). Nasal bone fractures were the most common (54.2%), and tripod fractures were the most common type of complex injuries (4.2%). The complication rate was 3.0%. Long-term epidemiological data regarding the natural history of sports-related facial bone fractures are important for the evaluation of existing preventative measures and for the development of new methods of injury prevention and treatment.

    The purpose of this study was to investigate the demographics, the type of impact, the site and the treatment of maxillofacial fractures sustained during baseball and softball to develop an effective preventive strategy. Data of 82 patients treated for baseball- and softball-related maxillofacial fractures at the Department of Oral and Maxillofacial Surgery, Nara Medical University between 1982 and 2007 were retrospectively analyzed. Injuries were found in 64 men in baseball and 16 men and two women in softball with average ages of 19.6 and 30.0 years, respectively. Fractures were caused by being hit by the ball in 61 patients followed by collision in 16 patients. Fractures of the mandible and the mid-face were found in 44 and 38 patients, respectively. The mental and angle region of the mandible and zygoma and alveolar bone of the maxilla were frequently involved. Treatment was mostly conservative. Open reduction and internal fixation were performed only in 15 patients. Most maxillofacial fractures in these sports were ball-related. Therefore, effective preventive means should be considered to protect against such injuries.

    The aim of this study was to analyze maxillofacial region fractures during the past 20 years in the Department of Maxillofacial Surgery in Prishtina. We have analyzed the histories of all patients with trauma who were hospitalized in the Department of Maxillofacial Surgery in Prishtina since the opening of the clinic in 1983 through 2005. Narrowing the subject of our research, we concentrated on fractures of the maxillofacial region treated at the Clinic of Maxillofacial Surgery for the period 2001-2005. We have analyzed those fractures and compared them with the period from 1983 to 2005 only when it was reasonable. During this period, 1,945 patients were treated for trauma in the maxillofacial region by the Department of Maxillofacial Surgery. This group included 19.8% females and 80.2% males. The largest age group were those between 20 and 20 years of age. Causes of trauma for both periods were predominantly traffic accidents; however, during the period 2001-2005, interpersonal conflicts were increasingly the cause of fractures. Interpersonal conflict as a cause of maxillofacial trauma has risen in recent years. With this increase the methods of treating fractures in this region are also changing.

    Stress fractures are relatively uncommon sports injuries and when they do occur, are mostly found in the lower limb. Stress fractures of the clavicle are particularly rare, having been described in a number of non-sport related pathologies, such as nervous tics and post radical neck dissection. In sport, there have only been seven cases reported in the literature. We report on a clavicle stress fracture in a 47-year-old male, partaking in recreational weight lifting activities. This is the first reported case of a non-union stress fracture of the clavicle. The patient underwent an open reduction and internal fixation and made a full recovery. PMID:21264151

    We present the orthodontic treatment of a patient with occlusal dysfunction after plastic surgery for multiple maxillofacial bone fractures caused by a traffic accident. The patient had mandibular deviation to the right because of inappropriate repositioning and fixation of the fractured bone and complete avulsion of both mandibular central incisors. The bilateral mandibular incisors, canines, and premolars were also suspected of partial avulsion or alveolar bone fracture. Several tests, including percussion and dental computed tomography, were performed on these teeth to rule out ankylosis and confirm tooth movement. Camouflage orthodontic treatment was carried out with expansion of the maxillary arch, alignment of both arches, and space closure between the mandibular lateral incisors to improve the occlusion. Good occlusion and interdigitation were obtained. Orthodontic treatment is useful for the rehabilitation of occlusal dysfunction caused by multiple maxillofacial bone fractures.

    The aim of this study was to investigate the trends and characteristic features of mandibular condyle fractures in elderly patients in terms of etiology, patterns, and treatment modalities. Records of 201 patients aged 65 years and older, who were treated for maxillofacial fractures at the Department of Oral and Maxillofacial Surgery, Kyushu Dental University, and Tohoku University from January 2002 to December 2013, were retrospectively analyzed. Patient records and radiographs were examined, with the following information: relevant medical history, cause of fracture, the presence and state of premolars and molars in the maxilla and mandible, number and location of mandible fracture, and method of treatment. As for the state of premolars and molars, premolars or molars in the mandible in contact with the maxilla were regarded as contacted. A fall was responsible for the majority of the fractures (173/201). With condyle fractures, there was a significant difference between the contacted and non-contacted group in regard to incidence. Furthermore, there was a significantly greater number of cases with symphysis and condyle combination fractures in the non-contacted group (70.9%) than in the contacted group (51.9%). As for the method of treatment, arthrocentesis was the most commonly employed. The present findings suggest that contacted molars in the maxilla and mandible have an influence on condyle fractures in elderly individuals. © 2014 John Wiley & Sons A/S.

    The fractures of facial structures lead to great morbidity. Cross-sectional studies are needed to evaluate the current state of maxillofacial traumas. Thus, this study aims to evaluate these experiences and to compare these results with the current literature. The medical records of the maxillofacial fracture cases hospitalized between January 2004 and November 2011 were examined. The age, sex, etiology, fracture localization and treatment method for each case were documented. The affected facial bones were grouped as mandible, maxilla, zygoma, naso-orbitoethmoid complex (NOEC) and blow-out. Nasal fractures were excluded. The cases were assigned to 3 groups with respect to age (below 16, above 65 and between 17 and 64). The chi Square test was used to assess the significance of the difference in mandibular fracture rates in the pediatric population compared to others. The total number of cases was 152. The total number of fractures was 185. Of the 152 cases, 117 were male and 35 were female. The average age was 31.4 (±18.3), ranging between 2 and 81. Thirty-one cases were 16 years old or less. Nine cases were 65 years old or more. Mandibular and zygomatic fractures were the most prevalent fractures in the adult group. Mandibular fractures were significantly more common in the pediatric age group compared to rest of the population (X(2), pOpen reduction and internal fixation was the most frequently conducted treatment modality in all age groups. Retrospective studies are important for the projection of future prospects. In summary, our results indicate that pediatric fractures are mostly in the lower face and usually affect the condylar region, which is consistent with the literature.

    Effective pain management is an essential component in the perioperative care of surgical patients. However, postoperative pain after maxillofacial fracture repair and its optimal therapy has not been described in detail. In a prospective cohort study, 95 adults rated their pain on the first postoperative day after maxillofacial fracture repair using the questionnaire of the Quality Improvement in Postoperative Pain Management (QUIPS) project. Quality Improvement in Postoperative Pain Management allowed for a standardized assessment of patients' characteristics and pain-related parameters. Overall, the mean maximal pain and pain on activity (numeric rating scales) were significantly higher in patients with mandibular fractures than in patients with midface fractures (P = 0.002 and P = 0.045, respectively). In patients with mandibular fractures, a longer duration of surgery was significantly associated with higher satisfaction with pain intensity (P = 0.015), but was more frequently associated with postoperative vomiting (P = 0.023). A shorter duration of surgery and an absence of preoperative pain counseling in these patients were significantly correlated to desire for more pain medication (P = 0.049 and P = 0.004, respectively). Patients with mandibular fractures that received opioids in the recovery room had significantly higher strain-related pain (P = 0.017). In patients with midface fractures, a longer duration of surgery showed significantly higher levels of decreased mobility (P = 0.003). Patients receiving midazolam for premedication had significantly less minimal pain (P = 0.021). Patients with mandibular fractures seem to have more postoperative pain than patients with midface fractures. Monitoring of postsurgical pain and a procedure-specific pain-treatment protocol should be performed in clinical routine.

    Full Text Available Introduction: Technologic improvement and increased production of car and motorcycle have led to the increased incidence of maxillofacial trauma all around the world. Injuries of maxillofacial region include fractures of mandible, maxilla, zygoma, orbit and nasal bone, which is due to different etiologic factors such as motor vehicle accidents, quarreling, fall, and sport-related and work- related accidents. The Purpose of this study was to evaluate the frequency of maxillofacial fracture in CT-scan radiographs in Shahid Sadoghi and Shahid Rahnemon emergency departments in Yazd from 2007 till 2010. Methods: In this retrospective study we assessed the medical files of all patients with maxillofacial traumawho were admitted at Shahid Sadoughi and Shahid Rahnemoun hospitals in ENT and surgery wards during a 4-year period. The information from patients' medical file and CT scan radiographs were recorded. At last 372 patients were evaluated. Results: In this study the age of patients showed to be between 20 and 29. Eighty six and fourteen percent of patients were males and females, respectively. Among all fractures, mandible fracture was the most frequent one (50.8%. The most frequent etiologic factor was accident (59% and the most frequent outcome was partial recovery (46.4% and death was observed in 0.8% of individuals. Conclusion: Results of this study showed that the most frequent etiologic factor of trauma to maxillofacial region is motor vehicle accident similar to other developing countries.

    The aim of this study was to establish the costs structure of medical treatment for the patients with maxillofacial fractures, to perform a treatment cost evaluation, describe the factors which considerably influence the costs and discover the ways of achieving financial savings in treated patients. The study group consisted of patients with maxillofacial fractures who were admitted and treated at the Department of Maxillofacial Surgery of the University Hospital Mostar in the period from January 2002 until December 2006. Data for the study were collected from the patients' databases, case histories and data obtained on the basis of individual payments for the treatment that was collected by Finance Department of the University Hospital of Mostar Most patients in this study were men (83%), of average age 34 +/- 19 years. Zygomatic bone fracture was the commonest injury. Open surgical procedure was performed in 84.7% of treated cases. The costs for the open procedure were considerably higher than conservative treatment. Medication cost made up a total of 37.9% and cost of hospital accommodation 27.3% out of total hospital charge. Cost reduction in treated patients with maxillofacial fractures should be achieved through protocols of urgent treatment of maxillofacial trauma patients immediately after sustaining an injury and with earlier discharge of the patients when postoperative complications are not expected.

    To characterize maxillofacial fractures due to traffic accidents in patients attending the Hospital Universitario San Vicente Fundación (Medellin-Colombia) from 1998 to 2010. A descriptive study (n =1609) was carried out with information from the medical records of patients meeting the inclusion criteria established by the general objective of the study. The variables consisted of sex, age, year, type and number of fractures, and type of vehicle. A descriptive analysis of the variables was performed and the frequency of fractures due to traffic accidents was calculated according to year and sex. Crude and adjusted odds ratios (aOR) were estimated to establish associations among age, type of vehicle, and the presence of two or more fractures with stratification by sex. The frequency of maxillofacial fractures due to traffic accidents increased in 2007 (men: n=198, women: n=35) and decreased from 2008 to 2010 in both sexes. Fractures were more frequent in persons aged <35 years (80%) and in men (82%). The highest frequency of fractures was observed in motorists. Male users of motorcycles (aOR=1.41; confidence interval 95% [95%CI]: 1.02- 1.94) and bicycles (aOR=1.61; 95%CI: 1.01- 2.56) were more likely to report two or more fractures compared with pedestrians, after adjustment for other variables. Most maxillofacial fractures occurred in men and in motorists. Future studies should analyze other determinants affecting the epidemiology of maxillofacial fractures. Strategies should be designed to improve the use of protective elements and drivers' knowledge and practices. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

    Computed tomography (CT) is the current method of study in maxillofacial region, which produces cross-sectional images of a specific area. There are still questions about methodology and radiation exposure. The aim of the present study is to evaluate the CT in diagnosis of fractures in maxillofacial region. 42 patients with traumatic injuries to the facial skeleton are examined. Fractures of maxilla are occurring in 14.6 % of patients with traumatic diseases. Fractures of maxilla and zygomatic bone are found in 29.3 percent of the traumatic event. Isolated nasal bone fracture is observed in 2.4% of ail fractures. Compound fractures constitute 17.1% of the tested fractures. This group of patients are positioned at second place in frequency. Mandibular fractures ranked first in frequency -36.6% of all traumatic lesions. The methods include: 1. Slice computed tomography in the axial and coronary projection 2. Spiral CT in axial projection and coronary one. 3. Cone Beam Computed Tomography. CT diagnosis is based on an analysis of all the images. It must comply with the data from other studies. When analyzing the results we found that the percentage of patients with primary diagnosis of fractured upper jaw is 11 %, while CT diagnosis of this percentage increases to 16%. The percentage of patients with primary diagnosis fracture of mandibula and CT diagnosis is almost identical. In the present study, 3D and CT have similar results in the detection of fractures. Three-dimensional images dearly show the spatial anatomy of the face, the presence of fragments, as well as monitoring of fracture lines. Key words; Fractures. Maxillofacial Area. CT

    The present study was undertaken to evaluate the efficacy of biodegradable plating system for fixation of maxillofacial fractures and to study the morbidity associated with the use of biodegradable plates and screws. This prospective study consisted of 10 patients with maxillofacial fractures requiring open reduction and internal fixation. Fractures with infection, comminuted and pathological fractures were excluded. All were plated with biodegradable system (Inion CPS) using standard plating principles and observed for a total period of 24 weeks. Characteristics of the fractures, ease of use of bioresorbable plate/screw system and post operative complications were assessed. Of total 10 patients, eight patients were of midface fracture and two pediatric patients with mandibular fracture, with nine male and one female. The mean age was 32.8 years. Out of 20 plates and 68 screws applied to the 10 fractures sites; there were three incidences of screw breakage with no other intraoperative difficulties. Paresthesia of the infraorbital nerve was present in two patients, and recovered completely in four weeks after surgery. Fracture reduction was considered to be satisfactory in all cases. One patient developed postsurgical infection and was managed with oral antibiotics and analgesics. Favorable healing can be observed through the use of biodegradable plates and screws to stabilize selected midface fractures in patients of all ages, as well as mandible fractures in early childhood, however further studies with more sample size are required.

    Full Text Available Background : Maxillofacial fractures can lead to substantial long-term functional, esthetic and psychological complications. Aim : The aim of this study is to evaluate these injuries in a Turkish Iranian population. Materials and Methods : A retrospective study of 170 patients with 210 maxillofacial fractures admitted to the emergency department of a central referral emergency hospital in the area over a 5 year period is presented. Patients′ data included demographic information, etiology, site and associated injuries and complications. Results : Road traffic accident was the commonest cause (40% and the age group of 21-30 comprised the biggest group (30%. Mandibular fractures outnumbered midface fractures (150vs.60. Ramus (21.5% and zygoma (26.5% were the commonest fracture regions respectively in mandible and midface. Male: female ratio was 3.8:1 Almost half of patients (46% had sustained associated injuries most of which was soft tissue laceration of the face (17.5%. 22 patient (13% had associated complication and the hemorrhage was the commonest form of that (9%. Conclusion : It seems that road traffic accidents continue to be the leading cause of maxillofacial fractures and there is an urgent need to implement enhanced regulations and monitoring on motor vehicular traffic.

    Objectives The facial bones are the most noticeable area in the human body, and facial injuries can cause significant functional, aesthetic, and psychological complications. Continuous study of the patterns of facial bone fractures and changes in trends is helpful in the prevention and treatment of maxillofacial fractures. The purpose of the current clinico-statistical study is to investigate the pattern of facial fractures over a 4-year period. Materials and Methods A retrospective analysis of 1,824 fracture sites was carried out in 1,284 patients admitted to SMG-SNU Boramae Medical Center for facial bone fracture from January 2010 to December 2013. We evaluated the distributions of age/gender/season, fracture site, cause of injury, duration from injury to treatment, hospitalization period, and postoperative complications. Results The ratio of men to women was 3.2:1. Most fractures occurred in individuals aged between teens to 40s and were most prevalent at the middle and end of the month. Fractures occurred in the nasal bone (65.0%), orbital wall (29.2%), maxillary wall (15.3%), zygomatic arch (13.2%), zygomaticomaxillary complex (9.8%), mandibular symphysis (6.5%), mandibular angle (5.9%), mandibular condyle (4.9%), and mandibular body (1.9%). The most common etiologies were fall (32.5%) and assault (26.0%). The average duration of injury to treatment was 6 days, and the average hospitalization period was 5 days. Eighteen postoperative complications were observed in 17 patients, mainly infection and malocclusion in the mandible. Conclusion This study reflects the tendency for trauma in the Seoul metropolitan region because it analyzes all facial fracture patients who visited our hospital regardless of the specific department. Distinctively, in this study, midfacial fractures had a much higher incidence than mandible fractures. PMID:26734557

    Full Text Available BACKGROUND: There are only few studies regarding the pattern and causes of maxillofacial fractures till date in Nepal and no such study in western and central Nepalese population has been conducted. The purpose of this study, therefore, was to describe the causes and the pattern of maxillofacial fractures in western and central part of Nepal over the period of 5 years. MATERIAL AND METHODS A retrospective analysis of maxillofacial fractures was conducted on 328 patients who were treated in the department of maxillofacial surgery. Data was extracted and analyzed based on age, sex, cause of injury and anatomic location. RESULT Young males of 3rd decade of life most commonly sustained the maxillofacial trauma. The commonest site involved was the zygomatic complex (42% when only mid face fractures was considered and parasymphysis (32% when only mandible was considered.The most common cause of injuries was road traffic accidents (289 patients; 88.1% followed by interpersonal violence (25 patients; 7.6 % and falls accounting for 4.2% of the all injuries. CONCLUSION The findings of this study suggest the need for expansion of the motorway network, ensuring compliance of strict traffic rules and regulations, replacing old vehicles without safety measures and implement school education in alcohol abuse.DOI: http://dx.doi.org/10.3126/jcmsn.v10i3.12771 Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 8-13

    Oral and maxillofacial defects often require bone grafts to restore missing tissues. Well-recognized donor sites include the anterior and posterior iliac crest, rib, and intercalvarial diploic bone. The proximal tibia has also been explored as an alternative donor site. The use of the tibia for bone graft has many benefits, such as procedural ease, adequate volume of cancellous and cortical bone, and minimal complications. Although patients rarely complain of pain, swelling, discomfort, or dysfunction, such as gait disturbance, both patients and surgeons should pay close attention to such after effects due to the possibility of tibial fracture. The purpose of this study is to analyze tibial fractures that occurring after osteotomy for a medioproximal tibial graft. An analysis was intended for patients who underwent medioproximal tibial graft between March 2004 and December 2011 in Inha University Hospital. A total of 105 subjects, 30 females and 75 males, ranged in age from 17 to 78 years. We investigated the age, weight, circumstance, and graft timing in relation to tibial fracture. Tibial fractures occurred in four of 105 patients. There were no significant differences in graft region, shape, or scale between the fractured and non-fractured patients. Patients who undergo tibial grafts must be careful of excessive external force after the operation.

    Full Text Available BackgroundBioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws.MethodsA total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA in 61 patients. Their mean age was 35.2 years (range, 15-84 years. Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla.ResultsComplications occurred in eight (3.4% of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction.ConclusionsInadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.

  8. Sport-related concussions

    Jéssica Natuline Ianof

    Full Text Available ABSTRACT Traumatic brain injury (TBI is a major cause of lifelong disability and death worldwide. Sport-related traumatic brain injury is an important public health concern. The purpose of this review was to highlight the importance of sport-related concussions. Concussion refers to a transient alteration in consciousness induced by external biomechanical forces transmitted directly or indirectly to the brain. It is a common, although most likely underreported, condition. Contact sports such as American football, rugby, soccer, boxing, basketball and hockey are associated with a relatively high prevalence of concussion. Various factors may be associated with a greater risk of sport-related concussion, such as age, sex, sport played, level of sport played and equipment used. Physical complaints (headache, fatigue, dizziness, behavioral changes (depression, anxiety, irritability and cognitive impairment are very common after a concussion. The risk of premature return to activities includes the prolongation of post-concussive symptoms and increased risk of concussion recurrence.

    2011-01-01

    Introduction: Maxillofacial trauma (MFT) is a common reason for attendance at Emergency Departments. The complex anatomy of the facial bones requires multiplanar imaging techniques for a proper evaluation. Objectives. To describe frequency and types of fractures in a series of patients with MFT evaluated by multi-slice computed tomography (MDCT) with multiplanar and 3D reconstructions. Materials and Methods: Facial bone CTs ordered for MFT by the Emergency Department from June 2008 to December 2009 were retrospectively reviewed. The following data were obtained: age, gender, cause of trauma, presence and type of fractures. Patients were evaluated with an 8-channel MDCT. Multiplanar reconstructions were performed in all cases using high resolution bone window and soft tissue window, as well as 3D reconstructions. Results: One-hundred and thirty-seven CTs were performed for MFT: 78 (57%) showed 131 fractures. Of these 78 patients, 52 (66%) were males and 26 (34%) were females; mean age 33 years old (range: 14-90 yrs.). Causes: 58 % were injuries from traffic accidents; 24% were injuries from fights; 13% were sport injuries; and 7% were due to miscellaneous etiologies. Type and frequency of fractures: 18.3% were orbital floor fractures, 16% were maxillary sinus fractures, 15.3% were nasal fractures, 13% were jaw fractures, 9.2% were orbital fractures, and 12.3% were fractures of the zygomatic-malar complex; two cases of Le Fort II-III fractures were also observed. Conclusions: Fractures were more common in males, in the age range from 15 to 35 years old. Most fractures, and the most complex ones, were caused by traffic accidents. The most common fracture, either isolated or associated with other fractures, was the orbital floor fracture. (authors)

    Full Text Available The number of elderly patients with maxillofacial trauma is rapidly increasing due to active lifestyles and longevity. Shimane prefecture has the fastest growing proportion of elderly individuals in Japan. The aim of this study was to reveal the distinctive features and treatment modes of mandibular fracture treatment mode in patients requiring hospitalization at the Department of Oral and Maxillofacial Surgery, Shimane University Hospital, Japan.Patient age, sex, period between injury and first consultation, years since injury, cause of injury, fracture site, treatment, and duration of hospitalization were evaluated. Univariate Poisson regression, relative risk with 95% confidence interval based on the Wald test, Fisher's exact test, and Kruskal-Wallis test were used to explore associations among clinical and demographic variables.In total, 305 patients were diagnosed with and hospitalized for mandibular fracture from 1980 to 2010. Younger age increased the risk for mandibular fracture. Incidence was higher in males than females, particularly in the young, but the male to female ratio decreased with age. The period until first hospital consultation decreased progressively over the study period. Fall was a much more frequent cause in patients aged ≥60 than in those aged <60 years. Mandibular fracture with condyle, symphysis, and angle involvement were most common and were associated with sex, age, and treatment mode. Length of hospitalization has decreased since 1980.In our department, patients aged ≥60 years accounted for a greater proportion of mandibular fracture cases than in many previous studies, reflecting the greater proportion of elderly residents in Shimane prefecture.

  12. Sports related to drowning.

    2016-09-01

    Aquatic sports are included in the top list of risky practices as the environment per se carries a possibility of death by drowning if not rescued in time. Not only are aquatic sports related to a high risk of death, but also all sports practiced on the water, over the water and on ice. Whatever the reason a person is in the water, drowning carries a higher possibility of death if the individual is unable to cope with the water situation, which may simply be caused by an inability to stay afloat and get out of the water or by an injury or disease that may lead to physical inability or unconsciousness. The competitive nature of sports is a common pathway that leads the sports person to exceed their ability to cope with the environment or simply misjudge their physical capability. Drowning involves some principles and medical interventions that are rarely found in other medical situations as it occurs in a deceptively hostile environment that may not seem dangerous. Therefore, it is essential that health professionals are aware of the complete sequence of action in drowning. This article focuses on the pulmonary injury in sports and recreational activities where drowning plays the major role. Copyright ©ERS 2016.

    Full Text Available Current study analyzes the characteristics and epidemiology of oral and nasal fractures and knowledge degree regarding the use of a mouthguard by an amateur university handball team inBrazil.  A cross-sectional study comprised 138 students who practiced the sport. They were interviewed on dental and nasal fractures and on the need of mouthguards in games such as amateur handball. Data were processed by descriptive analysis. Results showed that 19.6% had suffered some type of dental injury during the practice of sports, namely 40 fractured teeth; 12% had fractured nasal bones; 57% underwent head and neck injuries; 32% were unaware of the need to use a mouthguard during sports; 68% had heard of mouthguards, but only 4.5% of the interviewees made use of this protection device. There was a high prevalence of nasal and dental fractures in the group under analysis. The upper central incisors were most susceptible to fracture. Even though most athletes knew a mouthguard was needed during sports activities, only 4.5% actually used one.

    Maxillofacial imaging has evolved dramatically over the past two decades with development of new cross-sectional imaging techniques. Traditional maxillofacial imaging was based on plain films and dental imaging. However, today's advanced imaging techniques with CT and MRI have only been partially implemented for maxillofacial questions. This book bridges the gap between traditional maxillofacial imaging and advanced medical imaging. We have applied CT and MRI to a variety of maxillofacial cases and these are illustrated with high-quality images and multiple planes. A comprehensive chapter on imaging anatomy is also included. This book is useful for oral and maxillofacial radiologists, oral and maxillofacial surgeons, dentists, radiologists, plastic surgeons, head and neck surgeons, and others that work with severe maxillofacial disorders.

    145 patients (60 with phlegmons of submandibular and submental regions, 85--with fractures of mandible) were observed and treated with the use of moving pulse magnetic field (MPMF) produced by special apparatus (AMO-ATOS-E, , Saratov-city), 60 patients with the same pathology were treated by traditional physical methods and served as control. Use of MPMF led to quicker patient recovery: quicker reduction (if compared with traditional physical methods of treatment) of oedema and soft tissue inflammatory infiltration, quicker relief from inflammatory reaction (according to data of cytokinin profile), improvement of tissue blood supply in the region of fractures in patients with mandible fractures. As the result--we had shortening treatment terms of such patients and complication number reduction.

    The aim of this study was to analyze the pattern and treatment of craniomaxillofacial injuries in the northern part of Israel, within a Jewish majority and large Arab minority population. A 5-year retrospective study evaluated patients treated for craniomaxillofacial fractures. Fracture cause, type, site, and patient demographics were evaluated. Patient age ranged from 1 to 94 years with an average age of 36.7 years; 52% of the victims were Jews and 48% Arabs. There was male predilection in both sectors (78.3% vs 21.7%). The main site of injury was the zygomatic bone (33.5%) followed by nasal bone, orbital, mandible, frontal sinus, and maxillary fractures. The main etiology of injuries was falls (45.4%) with significantly more falls reported by females (52.1% vs 43.2% in males). Motor vehicle accidents caused injuries more frequent in males. Arabs experienced CMF fractures at a younger age compared to Jews (27.8 and 44.8 average age, respectively). In the elderly, the trend reversed where Jews were more prone to craniomaxillofacial fractures. Compared to their weight in the population, the Arab sector experiences more craniomaxillofacial injuries. The Jewish elderly population tends to reside in nursing homes where they are more susceptible to accidental falls, whereas young Arab males are more exposed to motor vehicle accidents and interpersonal violence. Falls were the main cause of injuries particularly in women. This may reflect the women's fear of reporting domestic violence. We believe that increased government investments in infrastructures and education will lower the incidence of craniomaxillofacial trauma and balance the gap between both sectors and sexes.

    Severe facial trauma is often associated with intracerebral injuries. So it seemed to be of interest to study stress propagation from face to neurocranium after a fistlike impact on the facial skull in a finite element analysis. A finite element model of the human skull without mandible consisting of nearly 740,000 tetrahedrons was built. Fistlike impacts on the infraorbital rim, the nasoorbitoethmoid region, and the supraorbital arch were simulated and stress propagations were depicted in a time-dependent display. Finite element simulation revealed von Mises stresses beyond the yield criterion of facial bone at the site of impacts and propagation of stresses in considerable amount towards skull base in the scenario of the fistlike impact on the infraorbital rim and on the nasoorbitoethmoid region. When impact was given on the supraorbital arch stresses seemed to be absorbed. As patients presenting with facial fractures have a risk for craniocerebral injuries attention should be paid to this and the indication for a CT-scan should be put widely. Efforts have to be made to generate more precise finite element models for a better comprehension of craniofacial and brain injury.

    Many studies are available in the literature on both classification and treatment of unilateral mandibular condyle fractures. To date however, controversy regarding the best treatment for unilateral mandibular condyle fractures remains. In this study, an attempt was made to quantify the level of agreement between a sample of maxillofacial surgeons worldwide, on the classification and treatment decisions in three different unilateral mandibular condyle fracture cases. In total, 491 of 3044 participants responded. In all three mandibular condyle fracture cases, a fairly high level of disagreement was found. Only in the case of a subcondylar fracture, assuming dysocclusion was present, more than 81% of surgeons agreed that the best treatment would be open reduction and internal fixation. Based on the study results, there is considerable variation among surgeons worldwide with regard to treatment of unilateral mandibular condyle fracture. 3D imaging in higher fractures tends to lead to more invasive treatment decisions.

    To determine the etiology and pattern of maxillofacial injuries in the Armed Forces of Pakistan in terms of anatomical distribution of injuries. Three hundred consecutive patients of Armed Forces of Pakistan with maxillofacial injuries reporting to AFID and admitted to the hospital or treated as out-patients in the oral surgery clinic, were included in this study. Isolated nasal bone and frontal sinus fractures were excluded from the study. Anatomical distribution, frequency and etiology of fractures, rank at job and occupational as well as personal hobbies were recorded. Descriptive analyses were used to determine mean, standard deviation, percentage and range values. The most frequent bone fractured was the mandible, which accounted for 159 cases (53%). The zygomatic complex was fractured in 51 cases (17%), the maxilla in 12 cases (4 %), and the alveolar process in 21 cases (7%). The most common cause was road traffic accident (168 cases; 56%), followed by accidental fall (69 cases; 23%), gunshot injuries (27 cases; 9%), sports related injuries (15 cases; 5%), and injury associated with a fight (12 cases; 4%); there were only 9 cases of animals related injuries (3%). In this series, mandible was the most commonly fractured facial bone, while road traffic accident was the most common etiological factor. Results could be influenced by the personal and working environment. (author)

    Full Text Available Jessica L Ford, Kenneth Ildefonso, Megan L Jones, Monna Arvinen-Barrow Department of Kinesiology, Integrative Health Care & Performance Unit, University of Wisconsin-Milwaukee, Milwaukee, WI, USA Abstract: To date, much research has been devoted to understanding how anxiety can affect sport performance, both in practice and in competitive settings. It is well known that sport has the potential for high levels of stress and anxiety, and that practicing and employing a range of psychological strategies can be beneficial in anxiety management. Equally, growing evidence also suggests that anxiety can play a role in sport injury prevention, occurrence, rehabilitation, and the return to sport process. The purpose of this paper is to provide current insights into sport-related anxiety. More specifically, it will provide the reader with definitions and theoretical conceptualizations of sport-related anxiety. This will be followed by making a case for considering the term "performance" to be broader than activities associated with sport-related performance in practice and competition, by including performance activities associated with sport injury prevention, rehabilitation, and the return to sport process. The paper will then highlight the importance of recognizing early signs and symptoms of anxiety, and the potential need for referral. Finally, the conclusions will emphasize the need for appropriate, client-specific, and practitioner competent care for athletes experiencing sport-related anxiety.

    Full Text Available BACKGROUND: Maxillofacial injuries occur in a significant number of trauma patients. Epidemiological assessments are essential to reaffirm patterns, identify new trends and develop clinical and research priorities for effective treatment and prevention of these injuries. OBJECTIVE: The aim of this study was to identify the epidemiological profile and risk factors associated with maxillofacial trauma treated at a referral emergency hospital for the Public Health System in the State Capital of Goiás, Brazil. MATERIAL AND METHODS: A cross-sectional study was designed including 530 patients with maxillofacial trauma, 76% male, with a mean age of 25.5±15.0 years. Data were collected between May 2003 and August 2004 over weekly shift-working periods. RESULTS: The main causes of trauma were traffic accidents (45.7% and physical assaults (24.3%, and differences in etiological factors were identified according to gender (p<0.001. The distribution of patients according to age and etiology showed significant differences for traffic accidents (p<0.01, physical assaults (p<0.001, falls (p<0.001 and sport injuries (p<0.01. In the multinomial logistic regression analysis (R² = 0.233; p<0.05, age was associated with injury in traffic accidents and falls (p<0.01, sports-related accidents were associated with males (p<0.05, and alcohol consumption with assaults and traffic accidents (p<0.001. Facial soft tissue lesions were found in 98% of patients and facial fractures in 51%. CONCLUSIONS: The significant association of maxillofacial trauma with young males and alcohol consumption reinforces the need for educational strategies and the development of policies for the prevention and reduction of associated damage in this specific risk group.

    Full Text Available Maxillofacial injuries are most commonly associated with falls, motor and vehicle accidents, sports-related trauma, and interpersonel violence. The complexity of mandibular condyle region and its anatomic proximity to other craniofacial structures complicate diagnosis and treatment. Thus, treatment approaches of mandibular condyle fracture are still controversial. In the literature, different success rates are reported about observation versus treatment, closed reduction versus open reduction and fixation methods. In the present article, controversial issues related to mandibular condyle fractures were reviewed under the light of current literature. In conclusion, the simplest way that can be done with the least risk of complication should be chosen during treatment planning. In addition, current adjunctive treatment methods accelerating healing of fracture should be considered. [Archives Medical Review Journal 2014; 23(4.000: 658-671

    Full Text Available Background & Objectives: The maxillofacial region, a complex anatomical structure, can be evaluated by conventional (plain films, Tomography, Multidetector Computed Tomography, Three-Dimensional Computed Tomography, Orthopantomogram and Magnetic Resonance Imaging. The study was conducted with objective of describing various forms of maxillofacial injuries, imaging features of different types of maxillofacial fractures and the advantage of using Three- Dimensional Computed Tomography reconstructed image. Materials & Methods: A hospital based cross-sectional study was conducted among 50 patients during April 2014 to September 2016 using Toshiba Aquilion Prime 160 slice Multi Detector Computed Tomography scanner.Results: The maxillofacial fractures were significantly higher in male population (88% than female population (12 %. Road traffic accidents were the most common cause of injury others being physical assault and fall from height. It was most common in 31-40 years (26% and 21-30 (24% years age group. Maxillary sinus was the commonest fracture (36% followed by nasal bone and zygomatic bone (30%, mandible and orbital bones (28%. Soft tissue swelling was the commonest associated finding. Three dimensional images (3 D compared to the axial scans missed some fractures. However, the extension of the complex fracture lines and degree of displacement were more accurately assessed. Complex fractures found were Le fort (6% and naso-orbito-ethmoid (4% fractures.Conclusion: The proper evaluation of complex anatomy of the facial bones requires Multidetector Computed Tomography which offers excellent spatial resolution enabling multiplanar reformations and three dimensional reconstructions for enhanced diagnostic accuracy and surgical planning.

    Sports-related concussions (SRCs) are traumatic events that affect up to 3.8 million athletes per year. The initial diagnosis and management is often instituted on the field of play by coaches, athletic trainers, and team physicians. SRCs are usually transient episodes of neurological dysfunction following a traumatic impact, with most symptoms resolving in 7-10 days; however, a small percentage of patients will suffer protracted symptoms for years after the event and may develop chronic neurodegenerative disease. Rarely, SRCs are associated with complications, such as skull fractures, epidural or subdural hematomas, and edema requiring neurosurgical evaluation. Current standards of care are based on a paradigm of rest and gradual return to play, with decisions driven by subjective and objective information gleaned from a detailed history and physical examination. Advanced imaging techniques such as functional MRI, and detailed understanding of the complex pathophysiological process underlying SRCs and how they affect the athletes acutely and long-term, may change the way physicians treat athletes who suffer a concussion. It is hoped that these advances will allow a more accurate assessment of when an athlete is truly safe to return to play, decreasing the risk of secondary impact injuries, and provide avenues for therapeutic strategies targeting the complex biochemical cascade that results from a traumatic injury to the brain.

    Patients with maxillofacial trauma require a careful evaluation due to the anatomical proximity of the maxillofacial region to the head and neck. Facial injuries can range from soft-tissue lacerations and nondisplaced nasal fractures to severe, complex fractures, eye injuries, and possible brain injury. Though the Advanced Trauma Life Support (ATLS) guidelines provide a framework for the management of trauma patients, they do not provide a detailed reference for many subtle or complex facial injuries. This issue adds a more comprehensive and systematic approach to the secondary survey of the maxillofacial area and emergency department management of injuries to the face. In addition to an overall review of maxillofacial trauma pathophysiology, associated injuries, and physical examination, this review will also discuss relevant imaging, treatment, and disposition plans.

    The goal in this review was to summarize the results of clinical neuroimaging studies performed in patients with sports-related concussion (SRC) who were referred to a multidisciplinar ypediatric concussion program. The authors conducted a retrospective review of medical records and neuroimaging findings for all patients referred to a multidisciplinary pediatric concussion program between September 2013 and July 2014. Inclusion criteria were as follows: 1) age ≤ 19 years; and 2) physician-diagnosed SRC. All patients underwent evaluation and follow-up by the same neurosurgeon. The 2 outcomes examined in this review were the frequency of neuroimaging studies performed in this population (including CT and MRI) and the findings of those studies. Clinical indications for neuroimaging and the impact of neuroimaging findings on clinical decision making were summarized where available. This investigation was approved by the local institutional ethics review board. A total of 151 patients (mean age 14 years, 59% female) were included this study. Overall, 36 patients (24%) underwent neuroimaging studies, the results of which were normal in 78% of cases. Sixteen percent of patients underwent CT imaging; results were normal in 79% of cases. Abnormal CT findings included the following: arachnoid cyst (1 patient), skull fracture (2 patients), suspected intracranial hemorrhage (1 patient), and suspected hemorrhage into an arachnoid cyst (1 patient). Eleven percent of patients underwent MRI; results were normal in 75% of cases. Abnormal MRI findings included the following: intraparenchymal hemorrhage and sylvian fissure arachnoid cyst (1 patient); nonhemorrhagic contusion (1 patient); demyelinating disease (1 patient); and posterior fossa arachnoid cyst, cerebellar volume loss, and nonspecific white matter changes (1 patient). Results of clinical neuroimaging studies are normal in the majority of pediatric patients with SRC. However, in selected cases neuroimaging can provide

    Craniomaxillofacial trauma is one of the most complex clinical conditions in contemporary maxillofacial surgery. Vital structures and possible functional and esthetic sequelae are important considerations following this type of trauma and intervention. Despite the best efforts of the primary surgery, there are a group of patients that will have poor outcomes requiring secondary reconstruction to restore form and function. The purpose of this study is to review current concepts on secondary reconstruction to the maxillofacial complex. The evaluation of a posttraumatic patient for a secondary reconstruction must include an assessment of the different subunits of the upper face, middle face, and lower face. Virtual surgical planning and surgical guides represent the most important innovations in secondary reconstruction over the past few years. Intraoperative navigational surgery/computed-assisted navigation is used in complex cases. Facial asymmetry can be corrected or significantly improved by segmentation of the computerized tomography dataset and mirroring of the unaffected side by means of virtual surgical planning. Navigational surgery/computed-assisted navigation allows for a more precise surgical correction when secondary reconstruction involves the replacement of extensive anatomical areas. The use of technology can result in custom-made replacements and prebent plates, which are more stable and resistant to fracture because of metal fatigue. Careful perioperative evaluation is the key to positive outcomes of secondary reconstruction after trauma. The advent of technological tools has played a capital role in helping the surgical team perform a given treatment plan in a more precise and predictable manner.

    Even though numerous reports on maxillofacial trauma exist, only a few give detailed information about work-related maxillofacial injuries. The purpose of this study was to reveal the significance of maxillofacial injuries related to accidents occurring at work by evaluating a large number of patients with maxillofacial injuries over a 9-year period. Out of the 8704 trauma patients treated between 1991 and 1999 in the Department of Oral and Maxillofacial Surgery at the University of Innsbruck, Austria, 463 (5.4%) were injured at work. All charts were reviewed and analyzed according to age, gender, cause of accident, occupation, type of injury, location and frequency of fractures. The highest incidence of maxillofacial injury was found among construction workers (a total of 124 patients, 26.8%), followed by craftsmen (102 patients, 22.0%) and office employees (69 patients, 14.9%). The sex distribution showed an overall male-to-female ratio of 11.8:1 and those in the age group most affected were between 20 and 29 years of age. The most frequent cause of injury was a blow in 48.4%, followed by falls and falls over obstacles, accounting for 27.9% and 7.1%, respectively. Of all trauma, 45.4% (210 persons) sustained 423 maxillofacial fractures, 31.7% (147 patients) suffered 232 dento-alveolar injuries, and 21.2% (98 people) showed 430 soft-tissue injuries. One-fifth (20.7%) of all patients displayed concomitant injuries with cerebral and cranial trauma being the most common. The probability of sustaining maxillofacial trauma at work is correlated to the nature of the occupation. Individuals (mostly men) using tools or machines at work are exposed to a much higher risk of work-related maxillofacial trauma.

    Sports-related dental injuries, such as tooth fracture, loosening, and avulsion, are a major concern among young athletes because they directly impair oral function. Although the preventive efficacy of mouthguards has been well established, the prevalence of sports-related dental injuries remains high among young athletes. The aim of this study is to identify the variables contributing to the risk of sports-related dental injuries by conducting a survey on large population of young athletes in Miyagi prefecture. A cross-sectional study was conducted with school-aged athletes (aged 6-15 years, n = 5735) using a self-reported questionnaire. The questionnaire examined general variables, including sex, age, and body mass index; sports-related variables, including sports-type, team level, activity schedule, break time, and verbal/physical abuse by coaches; and lifestyle variables related to free time, including screen-time and sleep duration. Their associations with sports-related dental injuries were examined using multivariate logistic regression models. The prevalence of sports-related dental injuries was 13.3% (763 of 5735 young athletes) and was higher in males (14.3%, 592 of 4132) than in females (10.7%, 171 of 1603; adjusted odds ratios [ORs] and 95% confidence intervals [CIs]: 1.48 [1.22-1.79], p sports-related dental injuries were evident for three variables-insufficient break time, verbal abuse, and physical punishment-in males (adjusted ORs [95% CI]: 1.35 [1.03-1.77], p = 0.032; 1.31 [1.05-1.62], p = 0.015; and 1.36 [1.06-1.75], p = 0.016, respectively) but not in females (adjusted ORs [95% CI]: 0.88 [0.53-1.47], p = 0.623; 1.29 [0.87-1.91], p = 0.206; and 0.97 [0.57-1.63], p = 0.894, respectively). Although our results might be based on the individual athlete's self-perception to the sports-related variables, our results suggest that insufficient break time, verbal abuse, and physical punishment from coaches are positively

    The population is rapidly aging and remaining more active over the age of 65. An increasing number of sports related injuries in individuals 65 and older are thus anticipated. The aim of this study is to analyze the epidemiology of sports injuries in the age group aged 65 and older. Data from the medical records of adults aged 65 years and older who were treated for sports-related injuries at a level one trauma center between December 1994 and February 2008 was collected and statistically analyzed. A total of 2635 patients met our inclusion criteria. There were 1647 men (62.5%) and 988 women (37.5%) with a mean age of 70.9 years. The yearly number of injuries doubled during the study period (1996-2007). The most common mechanism of injury was a simple fall from standing height (69%). Nearly 75% of all injuries occurred during alpine skiing, cycling or mountain climbing. The median Injury Severity Score was 4. Minor injuries and wounds (40%) were recorded most commonly followed by fractures (27%), sprains, ligament injuries (19%) and injuries of muscles and tendons (6%). The most frequent diagnoses were minor injuries to the head and ligament injuries around the knee joint. Injuries to the upper extremities occurred in 33.7%, injuries to the lower extremities in 29.4% and injuries to the head occurred in 20% of the patients. Women sustained substantially more fractures than men. Adults aged 65 and older are remaining active in sports, which results in higher numbers of sports related injuries in this age group. Identification of type, mechanism and distribution of the injuries can help with the recognition of risk factors for injury. This may enable us to develop appropriate preventative measures to reduce the incidence, and morbidity of such injuries.

    Concussion, also referred to as mild traumatic brain injury (TBI), is defined as a "complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces." Various symptoms may be observed in patients with concussions. All of these might not be evident at the time of the injury and be intermittent in their nature. It is estimated that 300,000 of the yearly TBIs in the United States are sports-related, the second leading cause for TBIs after motor vehicle accidents among people aged 15 to 24 years old. Due to some recently reported high profile injuries and deaths of sports personalities, sports-related concussion has seen increasing media and public interest in the last decade. We review the role of football in youth concussions and analyze the Nationwide Inpatient Sample from 2007 to 2009 to elucidate the outcome and costs associated with sports-related concussions of the youth in the United States. We also review the latest state legislative efforts to decrease the incidence of dangerous sports-related concussions in youth--the Louisiana Youth Concussion Act.

    Emergency department (ED) visits for sports-related traumatic brain injuries (TBIs) have risen. This study evaluated how the number and severity of admissions have changed as ED visits for sports-related TBIs have increased. A retrospective study of children aged 0 to 19 years at a level 1 trauma center was performed. Patients from 2002 to 2011 with a primary or secondary diagnosis of TBI were identified from the hospital's inpatient and outpatient trauma registries. Frequencies were used to characterize the population, χ(2) analysis was performed to determine differences between groups, and regression analysis looked at relationship between year and injury severity score or length of stay. Sport was responsible for injury in 3878 (15.4%) cases during the study period; 3506 (90.4%) were discharged from the hospital, and 372 (9.6%) were admitted. Seventy-three percent were male patients and 78% Caucasian; mean age was 13 ± 3.5 years. ED visits for sports-related TBIs increased 92% over the study period, yet there was no significant change (χ(2) = 9.8, df = 9, P = .37) in the percentage of children admitted. Mean injury severity score for those admitted decreased from 7.8 to 4.8 (β = -0.46; P = .006); length of stay trended downward (β = -0.05; P = .05). The percentage of children being admitted from the ED with sports-related TBI has not changed over the past 10 years. The severity of admitted sports-related TBI is decreasing. Additional research is needed to correlate these trends with other TBI mechanisms.

    2017-05-01

    Stress injuries (stress fractures and stress reactions) of the lumbosacral region are one of the causes of sports-related lower back pain in young individuals. These injuries can be detected by bone marrow edema lesion on MRI. However, little is known about the prevalence and clinical features of early stage lumbosacral stress injuries. This study aimed to evaluate the epidemiology of lumbosacral stress injuries. A total of 312 patients (under 18 years of age) who complained of sports-related lower back pain that had lasted for ≥7 days underwent magnetic resonance imaging (MRI) scans. We reviewed patients' records retrospectively. MRI showed that 33.0% of the patients had lumbar stress injuries and 1.6% had sacral stress injuries. Lumbar stress injuries were more common in males than in females and were found in 30% of 13- to 18-year-old patients. About 50% of the patients that participated in soccer or track and field were diagnosed with lumbar stress injuries. No clinical patterns in the frequencies of sacral stress injuries were detected due to the low number of patients that suffered this type of injury. Plain radiography is rarely able to detect the early stage lesions associated with lumbosacral stress injuries, but such lesions can be detected in the caudal-ventral region of the pars interarticularis on sagittal computed tomography scans. Thirty-three percent of young patients that complained of sports-related lower back pain for ≥7 days had lumbar stress injuries, while 1.6% of them had sacral stress injuries. Clinicians should be aware of the existence of these injuries. MRI is useful for diagnosing lumbosacral stress injuries.

    Full Text Available Background and Aims: Despite advances in trauma management, treatment of the consequent infections has remained a major challenge. Antibiotic prophylaxis has been widely applied to reduce such infections. Although bacteria are present in most body parts, severe infections after treatment are less frequent in the head and neck of healthy individuals. The aim of the present study was to review the reasonable application of antibiotic prophylaxis in maxillofacial trauma. Materials and Methods: In this review article, PubMed and Google Scholar databases were searched for studies on antibiotic prophylaxis in maxillofacial trauma published during 2000-2014. Conclusion: Antibiotics were not prescribed for tears and small clean wounds in the face and mouth. However, prophylaxis was applied for extensive mouth injuries which involved the facial skin. In case of maxillofacial fractures, 24-hour administration of antibiotics sufficed for compound fractures of the mandible and other parts of the face. Antibiotics were not required in other types of fractures. Prophylaxis should be applied over short pre- or post-operative periods based on the severity and complexity of maxillofacial fractures and their relations with intra- and extraoral environments. Apparently, more detailed studies are warranted to further clarify the subject.

    2008-02-01

    With the increased conditioning, size, and speed of professional athletes and the increase in individuals engaging in sports and recreational activities, there is potential for rising numbers of traumatic brain injuries in sports. Fortunately, parallel strides in basic research technology and improvements in computer and video technology have created a new era of discovery in the study of the biomechanical aspects of sports-related head injuries. Although prevention will always be the most important factor in reducing the incidence of sports-related traumatic brain injuries, ongoing studies will lead to the development of newer protective equipment, improved recognition and management of concussions on the field of play, and modification of rules and guidelines to make these activities safer and more enjoyable.

    The field of sport-related concussion has grown exponentially over the past decade, with more concussion-specific clinics being identified in major hospital systems as well as independent practitioner's offices. To date, there is no standardized in-office protocol for managing ongoing symptoms. The University of Pittsburgh Medical Center (UPMC) Sports Concussion Program, established in 2000, is one of the largest programs in the USA, pioneering the way in clinical management, research, and education of sport-related concussion. This report will outline the essential components of a successful concussion clinic, using the UPMC Sports Concussion Program as a case example of best practice. We will share several case studies illustrating the individualized and complex nature of this injury, as well as review important rehabilitation components. © 2014 S. Karger AG, Basel.

    Although growing awareness about the potential long-term deleterious effects of sport-related concussion has led to increased attention to the risks of collision sports, calls to ban these sports, such as American football, might be premature. Collision sports have a relatively high incidence of concussions, but participation in these sports also confers a host of benefits. In addition, the associated risks of participation, including concussion, have not been definitively shown to outweigh the benefits they provide, and the risk-benefit ratio might vary among individuals. The risks of concussion and repetitive concussions associated with collision sports are unknown in the general population and not well characterized even in elite athlete populations. In this article, we discuss current knowledge on sports-related concussion, its neurological consequences, and implications for regulation of the practice of collision sports.

    Best practice recommendations for sports-related emergency preparation include implementation of venue-specific emergency action plans (EAPs), access to early defibrillation, and first responders-specifically coaches-trained in cardiopulmonary resuscitation and automated external defibrillator (AED) use. The objective was to determine whether high schools had implemented these 3 recommendations and whether schools with a certified athletic trainer (AT) were more likely to have done so. Schools with an AT were more likely to have implemented the recommendations. Cross-sectional study. Level 4. All Oregon School Activities Association member school athletic directors were invited to complete a survey on sports-related emergency preparedness and AT availability at their school. Chi-square and Fisher exact tests were used to analyze the associations between emergency preparedness and AT availability. In total, 108 respondents (37% response rate) completed the survey. Exactly half reported having an AT available. Only 11% (95% CI, 6%-19%) of the schools had implemented all 3 recommendations, 29% (95% CI, 21%-39%) had implemented 2, 32% (95% CI, 24%-42%) had implemented 1, and 27% (95% CI, 19%-36%) had not implemented any of the recommendations. AT availability was associated with implementation of the recommendations (χ 2 = 10.3, P = 0.02), and the proportion of schools with ATs increased with the number of recommendations implemented (χ 2 = 9.3, P Schools with an AT were more likely to implement venue-specific EAPs (52% vs 24%, P schools were inadequately prepared for sports-related emergencies. Schools with an AT were more likely to implement some, but not all, of the recommendations. Policy changes may be needed to improve implementation. Most Oregon high schools need to do more to prepare for sports-related emergencies. The results provide evidence for sports medicine professionals and administrators to inform policy changes that ensure the safety of athletes.

    Although much of the lay media attention surrounding sport-related concussion (SRC) focuses on professional athletes, SRC is a common injury in pediatric sports. The anatomy, biomechanics, and response to injury of the developing pediatric brain differ from those of the adult. Similarly, the neurocognitive abilities of the child are developing more rapidly than in an adult. The effects of concussive brain injury on the life of a child are different from those of an adult. This article focuses on the aspects of SRC that are specific to the younger athletes. Copyright © 2011 Elsevier Inc. All rights reserved.

    Mandible fractures account for a significant portion of maxillofacial injuries and the evaluation, diagnosis, and management of these fractures remain challenging despite improved imaging technology and fixation techniques. Understanding appropriate surgical management can prevent complications such as malocclusion, pain, and revision procedures. Depending on the type and location of the fractures, various open and closed surgical reduction techniques can be utilized. In this article, the authors review the diagnostic evaluation, treatment options, and common complications of mandible fractures. Special considerations are described for pediatric and atrophic mandibles.

    Participation in sports is a popular activity for children across the country. Prevention of sports-related injuries can be improved if details of injuries are documented and studied. A retrospective medical record review of injuries that occurred as a direct result of sports participation (both organized and non-organized play) from November 2006 to November 2007. Because the vast majority of injuries were a result of participation in football or basketball, these injuries were focused upon. The injuries specifically examined were closed head injury (CHI), lacerations and fractures. There were 350 football and 196 basketball injuries (total 546). Comparing injuries between the two groups fractures were found to be more prevalent in football compared to basketball (z = 2.14; p = 0.03; 95%CI (0.01, 0.16)). Lacerations were found to be less prevalent among helmeted patients than those without helmets. (z = 2.39; p = 0.02; 95%CI (-0.17,-0.03)). CHI was more prevalent among organized play compared to non-organized (z = 3.9; pfootball related visits, organized play had a higher prevalence of injury compared to non-organized play (z = 2.87; p = 0.004; 95%CI (0.04.0.21)). No differences in fracture or laceration prevalence were found between organized and non-organized play. Football and basketball related injuries are common complaints in a pediatric Emergency Department. Frequently seen injuries include CHI, fractures and lacerations. In our institution, fractures were more prevalent among football players and CHI was more prevalent among organized sports participants.

    Computed tomography has the ability to evaluate maxillofacial trauma quickly. The well-known contrast resolution capabilities of CT play a role in the usefulness of this modality. However, it is the image manipulation capability which is of singular advantage in these cases. The spatial resolution of computed tomography has matched that of conventional pluridirectional tomography in current generation equipment. Since a set of axial CT sections can be obtained with automatic table incrementation within 12 minutes, the information content per time of study ratio is improved over that of conventional tomography, despite the fact that image reformation requires extra time on the part of the radiologist. Radiation savings are significantly in favor of computed tomography as well. In the authors' experience, computed tomography is the primary diagnostic imaging modality used in the evaluation of complex facial trauma, after routine screening films are obtained

    To review relevant literature regarding the effect of concussion on vestibular function, impairments, assessments and management strategies. REASONING: Dizziness and balance impairments are common following sport-related concussion. Recommendations regarding the management of sport-related concussion suggest including tests of balance within the multifactorial assessment paradigm for concussive injuries. The literature was searched for guidelines and original studies related to vestibular impairments following concussion, oculomotor and balance assessments and treatment or rehabilitation of vestibular impairments. The databases searched included Medline, CINAHL, Sport Discus and the Cochrane Database of Systematic Reviews through October 2013. Dizziness following concussion occurs in ∼67-77% of cases and has been implicated as a risk factor for a prolonged recovery. Balance impairments also occur after concussion and last 3-10 days post-injury. Assessments of balance can be done using both clinical and instrumented measures with success. Vestibular rehabilitation has been shown to improve outcomes in patients with vestibular impairments, with one study demonstrating success in decreasing symptoms and increasing function following concussion. Best practices suggest that the assessment of vestibular function through cranial nerve, oculomotor and balance assessments are an important aspect of concussion management. Future studies should evaluate the effectiveness of vestibular rehabilitation for improving patient outcomes.

    A normally functioning hip joint is imperative for athletes who use their lower extremities with running, jumping, or kicking activities. Sports-related injuries of the hip and groin are far less frequent than injuries to the more distal aspect of the extremity, accounting for less than 10% of lower extremity injuries. Despite the lower incidence, hip and groin injuries can lead to significant clinical and diagnostic challenges related to the complex anatomy and biomechanical considerations of this region. Loads up to 8 times normal body weight have been documented in the joint in common daily activities, such as jogging, with significantly greater force expected during competitive athletics. Additionally, treatment for hip and groin injuries can obviate the participation of medical and surgical specialties, with a multidisciplinary approach frequently required. Delay in diagnosis and triage of these injuries may cause loss of time from competition and, potentially, early onset of degenerative changes. Magnetic resonance imaging (MRI) of the hip has proven to be the gold standard for the diagnosis of sports-related hip and groin injuries in the setting of negative radiographs. With its exquisite soft tissue contrast, multiplanar capabilities, and lack of ionizing radiation, MRI is unmatched in the noninvasive diagnosis of intra-articular and extra-articular pathology, as well as intraosseous processes. This review focuses on MRI of common athletic injuries of the hip and groin, including acetabular labral tears, femoral acetabular impingement syndrome, muscle injuries around the hip and groin (including athletic pubalgia), and athletic osseous injuries.

    Sport-related head injuries are a common clinical problem. Most head injuries in young athletes are mild traumatic brain injuries or concussions. The highest number of sport-related concussions has been reported in American football. In addition to the well described physical and psychosocial growth, there is ongoing neurocognitive development of the brain during childhood and through adolescence. This developmental process has direct implications in the assessment and management of head injuries in young athletes. Research on the management and long-term outcome following brain injuries in young athletes is limited. Traditionally, the assessment of concussion has been based on clinical history and physical and neurological examination. Increasingly, neuropsychological testing, especially computerised testing, is providing objective measures for the initial assessment and follow-up of young athletes following brain injuries. Numerous guidelines have been published for grading and return to play criteria following concussion; however, none of these have been prospectively validated by research and none are specifically applicable to children and adolescents.

  8. Radiologic assessment of maxillofacial, mandibular, and skull base trauma

    Cranio-maxillofacial injuries affect a significant proportion of trauma patients either in isolation or concurring with other serious injuries. Contrary to maxillofacial injuries that result from a direct impact, central skull base and lateral skull base (petrous bone) fractures usually are caused by a lateral or sagittal directed force to the skull and therefore are indirect fractures. The traditional strong role of conventional images in patients with isolated trauma to the viscerocranium is decreasing. Spiral multislice CT is progressively replacing the panoramic radiograph, Waters view, and axial films for maxillofacial trauma, and is increasingly being performed in addition to conventional films to detail and classify trauma to the mandible as well. Imaging thus contributes to accurately categorizing mandibular fractures based on location, into alveolar, mandibular proper, and condylar fractures - the last are subdivided into intracapsular and extracapsular fractures. In the midface, CT facilitates attribution of trauma to the categories central, lateral, or combined centrolateral fractures. The last frequently encompass orbital trauma as well. CT is the imaging technique of choice to display the multiplicity of fragments, the degree of dislocation and rotation, or skull base involvement. Transsphenoid skull base fractures are classified into transverse and oblique types; lateral base (temporal bone) trauma is subdivided into longitudinal and transverse fractures. Supplementary MR examinations are required when a cranial nerve palsy occurs in order to recognize neural compression. Early and late complications of trauma related to the orbit, anterior cranial fossa, or lateral skull base due to infection, brain concussion, or herniation require CT to visualize the osseous prerequisites of complications, and MR to define the adjacent brain and soft tissue involvement.

    Full Text Available Sport-related concussion is known to affect a variety of brain functions. However, the impact of this brain injury on cerebral autoregulation (CA is poorly understood. Thus, the goal of the current study was to determine the acute and cumulative effects of sport-related concussion on indices of dynamic CA. Toward this end, 179 elite, junior-level (age 19.6 ± 1.5 years contact sport (ice hockey, American football athletes were recruited for preseason testing, 42 with zero prior concussions and 31 with three or more previous concussions. Eighteen athletes sustained a concussion during that competitive season and completed follow-up testing at 72 h, 2 weeks, and 1 month post injury. Beat-by-beat arterial blood pressure (BP and middle cerebral artery blood velocity (MCAv were recorded using finger photoplethysmography and transcranial Doppler ultrasound, respectively. Five minutes of repetitive squat–stand maneuvers induced BP oscillations at 0.05 and 0.10 Hz (20- and 10-s cycles, respectively. The BP–MCAv relationship was quantified using transfer function analysis to estimate Coherence (correlation, Gain (amplitude ratio, and Phase (timing offset. At a group level, repeated-measures ANOVA indicated that 0.10 Hz Phase was significantly reduced following an acute concussion, compared to preseason, by 23% (−0.136 ± 0.033 rads at 72 h and by 18% (−0.105 ± 0.029 rads at 2 weeks post injury, indicating impaired autoregulatory functioning; recovery to preseason values occurred by 1 month. Athletes were cleared to return to competition after a median of 14 days (range 7–35, implying that physiologic dysfunction persisted beyond clinical recovery in many cases.

    2006-01-01

    Sports-related shoulder pain and injuries represent a common problem. In this context, glenohumeral instability is currently believed to play a central role either as a recognized or as an unrecognized condition. Shoulder instabilities can roughly be divided into traumatic, atraumatic, and microtraumatic glenohumeral instabilities. In athletes, atraumatic and microtraumatic instabilities can lead to secondary impingement syndromes and chronic damage to intraarticular structures. Magnetic resonance (MR) arthrography is superior to conventional MR imaging in the diagnosis of labro-ligamentous injuries, intrinsic impingement, and SLAP (superior labral anteroposterior) lesions, and thus represents the most informative imaging modality in the overall assessment of glenohumeral instability. This article reviews the imaging criteria for the detection and classification of instability-related injuries in athletes with special emphasis on the influence of MR findings on therapeutic decisions.

    This literature review evaluates the significance of dental injuries and their relationship to specific sports activities. Many studies have been published on individual sports or groups of sports but most pertain to specific age groups or levels of competition. Research suggests that many sports that do not require mouthguards should encourage male and female participants to use orofacial protectors. Athletes, coaches, athletic directors, athletic trainers, parents, and members of the dental community should be aware of how individuals who participate in sporting activities are at risk for dental trauma. Any sport where the potential for dental trauma can exist (such as basketball, soccer, or wrestling) should consider utilizing mouthguards to protect the competitors. The establishment of mouthguard programs for athletes of all ages, genders, and sports may help to reduce the incidence of dental trauma. A sports-related, orofacial/dental trauma reporting system is considered.

    The number of athletes with disabilities participating in organized sports and the popularity of the Paralympic Games is steadily increasing around the world. Despite this growing interest and the fact that participation in sports places the athlete at risk for injury, there are few studies concerning injury patterns, risk factors, and prevention strategies of injuries in disabled athletes. In this systematic literature search and critical review, we summarize current knowledge of the epidemiology of sports-related injuries in disabled athletes and describe their characteristics, incidence, prevalence, and prevention strategies. The outcomes of interest were any injury, either an acute trauma or an overuse event. PubMed, EMBASE, CINAHL, and Google Scholar were systematically searched and 25 of 605 identified studies met the inclusion criteria. Lower extremity injuries were more common in walking athletes, whereas upper extremity injuries were more prevalent in wheelchair athletes. The methodologies and populations varied widely between the studies. Few studies were sports or disability specific, which makes it difficult to determine specific risk factors, and few studies reported injury severity and prevention of injuries. Further longitudinal, systematic sports and disability specific studies are needed in order to identify and prevent injuries in athletes with disabilities. © 2014 John Wiley & Sons A/S.

    2017-06-01

    Concussions are becoming increasingly important to manage properly as sports participation continues to rise. Repeated injuries occurring before the brain has had a chance to recover from an initial insult are particularly dangerous and must be prevented. Although much national media attention has been devoted to concussions in professional sports, it is important to appreciate that athletes in any age group, children and adolescents in particular, are at risk of sports-related concussion. It is crucial to remove an athlete from play any time concussion is suspected. Once removed from play, recovery then begins with a period of cognitive and physical rest, followed by a gradual return to cognitive and athletic activities as symptoms resolve. Children and adolescents pose a unique challenge to the clinician managing their recovery, as the physical and cognitive rest periods required often involve time away from school and sports, which can be academically detrimental and socially isolating. Recently developed sideline assessment tools have greatly aided the urgent sideline assessment of an athlete suspected of having a concussion. In this article, a brief review of current guidelines is presented in tandem with the authors' preferred treatment of concussion.

    The on-field diagnosis of sports-related concussion (SRC) is complicated by the lack of an accurate and objective marker of brain injury. To compare subject-specific changes in the astroglial protein, S100B, before and after SRC among collegiate and semi-professional contact sport athletes, and compare these changes to differences in S100B before and after non-contact exertion. Longitudinal cohort study. From 2009-2011, we performed a prospective study of athletes from Munich, Germany, and Rochester, New York, USA. Serum S100B was measured in all SRC athletes at pre-season baseline, within 3 hours of injury, and at days 2, 3 and 7 post-SRC. Among a subset of athletes, S100B was measured after non-contact exertion but before injury. All samples were collected identically and analyzed using an automated electrochemiluminescent assay to quantify serum S100B levels. Forty-six athletes (30 Munich, 16 Rochester) underwent baseline testing. Thirty underwent additional post-exertion S100B testing. Twenty-two athletes (16 Rochester, 6 Munich) sustained a SRC, and 17 had S100B testing within 3 hours post-injury. The mean 3-hour post-SRC S100B was significantly higher than pre-season baseline (0.099±0.008 µg/L vs. 0.058±0.006 µg/L, p = 0.0002). Mean post-exertion S100B was not significantly different than the preseason baseline. S100B levels at post-injury days 2, 3 and 7 were significantly lower than the 3-hour level, and not different than baseline. Both the absolute change and proportional increase in S100B 3-hour post-injury were accurate discriminators of SRC from non-contact exertion without SRC (AUC 0.772 and 0.904, respectively). A 3-hour post-concussion S100B >0.122 µg/L and a proportional S100B increase of >45.9% over baseline were both 96.7% specific for SRC. Relative and absolute increases in serum S100B can accurately distinguish SRC from sports-related exertion, and may be a useful adjunct to the diagnosis of SRC.

    To summarize the clinical characteristics and outcomes of pediatric sports-related concussion (SRC) patients who were evaluated and managed at a multidisciplinary pediatric concussion program and examine the healthcare resources and personnel required to meet the needs of this patient population. We conducted a retrospective review of all pediatric SRC patients referred to the Pan Am Concussion Program from September 1st, 2013 to May 25th, 2015. Initial assessments and diagnoses were carried out by a single neurosurgeon. Return-to-Play decision-making was carried out by the multidisciplinary team. 604 patients, including 423 pediatric SRC patients were evaluated at the Pan Am Concussion Program during the study period. The mean age of study patients was 14.30 years (SD: 2.32, range 7-19 years); 252 (59.57%) were males. Hockey (182; 43.03%) and soccer (60; 14.18%) were the most commonly played sports at the time of injury. Overall, 294 (69.50%) of SRC patients met the clinical criteria for concussion recovery, while 75 (17.73%) were lost to follow-up, and 53 (12.53%) remained in active treatment at the end of the study period. The median duration of symptoms among the 261 acute SRC patients with complete follow-up was 23 days (IQR: 15, 36). Overall, 25.30% of pediatric SRC patients underwent at least one diagnostic imaging test and 32.62% received referral to another member of our multidisciplinary clinical team. Comprehensive care of pediatric SRC patients requires access to appropriate diagnostic resources and the multidisciplinary collaboration of experts with national and provincially-recognized training in TBI.

    Most high-grade renal injuries (American Association for Surgery of Trauma (AAST) grades III-V) result from motor vehicle collisions associated with numerous concomitant injuries. Sports-related blunt renal injury tends to have a different mechanism, a solitary blow to the flank. We hypothesized that high-grade renal injury is often isolated in sports-related renal trauma. We identified patients with AAST grades III-V blunt renal injuries from four level 1 trauma centres across the United States between 1/2005 and 1/2014. Patients were divided into "Sport" or "Non-sport" related groups. Outcomes included rates of hypotension (systolic blood pressure 110bpm), concomitant abdominal injury, and procedural/surgical intervention between sports and non-sports related injury. 320 patients met study criteria. 18% (59) were sports-related injuries with the most common mechanisms being skiing, snowboarding and contact sports (25%, 25%, and 24%, respectively). Median age was 24 years for sports and 30 years for non-sports related renal injuries (p=0.049). Males were more commonly involved in sports related injuries (85% vs. 72%, p=0.011). Median injury severity score was lower for sports related injuries (10 vs. 27, pinjury scale scores. Sports related trauma was more likely to be isolated without other significant injury (69% vs. 39% (psports and non-sports renal injuries (p=0.30). Sports injuries had lower transfusion (7% vs. 47%, psports vs. 18% non-sports, p=0.95). High-grade sports-related blunt renal trauma is more likely to occur in isolation without other abdominal or thoracic injuries and clinicians must have a high suspicion of renal injury with significant blows to the flank during sports activities.

    Full Text Available Purpose: This study was conducted to find the epidemiological characteristics of maxillofacial trauma in the Western region of Nepal. Materials and Methods: All the trauma patients attending the Department of Oral and Maxillofacial surgery in 4 years period at a tertiary center in Western Nepal were included in the study. The incidence, prevalence, age and sex distribution, etiologies and types as well as seasonal and daily variation of maxillofacial trauma were studied. Results: Maxillofacial trauma with male (71.55% predominance was seen. Road traffic accidents (RTA, 46.5% were the most common cause, and 41.65% of fracture cases due to RTA were under the influence of alcohol. Accidents were more common on the rural roads (38.9%, and majorities (43.3% were due to motorcycle accidents. They were more common on Friday (36.7% and in winter seasons (51.2%. The mandible fractures (65.85% were more common than midface fractures (53.58% and 19.44% of the fractures were combined fractures. Parasymphysis in mandible (32.16% and zygoma (39.09% in midface were the most common type of fracture. Conclusion: The increased incidence of maxillofacial trauma following RTA under the influence of alcohol noted in this study reveals the need for formulating preventive measures in the Western region of Nepal. Need to aware people to avoid drink and drive proper traffic management, prevention of carrying excessive passengers, especially on the rooftop of vehicles on the highway and disposal of out of date vehicles and timely maintenance of faulty roads is a must.

    The objectives of this study were twofold: (1) to examine the prevalence of emotional symptoms among children and adolescents with a sports-related concussion (SRC) who were referred to a multidisciplinary pediatric concussion program and (2) to examine the prevalence, clinical features, risk factors, and management of postinjury psychiatric outcomes among those in this clinical population. The authors conducted a retrospective chart review of all patients with SRC referred to a multidisciplinary pediatric concussion program between September 2013 and October 2014. Clinical assessments carried out by a single neurosurgeon included clinical history, physical examination, and Post-Concussion Symptom Scale (PCSS) scoring. Postinjury psychiatric outcomes were defined as a subjective worsening of symptoms of a preinjury psychiatric disorder or new and isolated suicidal ideation or diagnosis of a novel psychiatric disorder (NPD). An NPD was defined as a newly diagnosed psychiatric disorder that occurred in a patient with or without a lifetime preinjury psychiatric disorder after a concussion. Clinical resources, therapeutic interventions, and clinical and return-to-play outcomes are summarized. One hundred seventy-four patients (mean age 14.2 years, 61.5% male) were included in the study. At least 1 emotional symptom was reported in 49.4% of the patients, and the median emotional PCSS subscore was 4 (interquartile range 1-8) among those who reported at least 1 emotional symptom. Overall, 20 (11.5%) of the patients met the study criteria for a postinjury psychiatric outcome, including 14 patients with an NPD, 2 patients with isolated suicidal ideation, and 4 patients with worsening symptoms of a preinjury psychiatric disorder. Female sex, a higher initial PCSS score, a higher emotional PCSS subscore, presence of a preinjury psychiatric history, and presence of a family history of psychiatric illness were significantly associated with postinjury psychiatric outcomes

    Sports-related violence is a form of interpersonal violence. Violence that occurs in and around the sporting world can have potentially severe physical and psychological repercussions for those involved. Although scholars in a wide range of disciplines have addressed three of the subsets of sports-related violence, they have done so without regard to the interconnected nature of the subsets, choosing instead to look at hazing, brawling, and foul play as independent problems. By separating hazing, brawling, and foul play and failing to recognize that their connection to sport connects them, scholars fail to see how sports-related violence is a broad example of interpersonal violence. This review describes some of the academic literature, primarily from the United States, and identifies similar themes and prevention suggestions that appear across disciplines. It also argues that the three subsets are an interconnected whole of sports-related violence that deserves more detailed study.

    Full Text Available Abstract Background In spite of employing numerous devices improving the safety in motor vehicles, traffic accidents are still among the main reasons of maxillofacial injuries. The maxillofacial injuries remain the serious clinical problem because of the specificity of this anatomical region. The knowledge of etiologic factors and mechanisms of injuries can be helpful in a satisfactory trauma prevention. The aim of this study was to find out the incidence and the pattern of maxillofacial injuries resulting from traffic accidents in the patients treated in the Department of Maxillofacial Surgery (Silesian Medical Academy in Katowice, Poland from January 2001 to December 2005. Methods The material consisted of 1024 case records of patients with maxillofacial injuries treated in the Maxillofacial Surgery Department of Silesian Medical Academy. The detailed analysis was carried out on the case records of 198 patients in the age of 3 to 68 with maxillofacial injuries resulting from traffic accidents. On the basis of data from a history, examination on admission, consultations and radiological examinations, patients' age and gender, we obtained the information on a pattern of injury and detailed description of an accident (the date and the time of an accident, the role of the patient in an accident. Results The traffic accidents were the cause of 19,93% maxillofacial injuries in the analyzed period of time. Most of the patients had injuries to the soft tissues of the face (22,21%, followed by tooth and alveolar process injuries (20,71% and mandibular fractures (18,69%. All the types of injuries were more common in men than in women. The majority of the patients were car drivers followed by car passengers, pedestrians, cyclists and motor cyclists. The peak age of the patients was between 18 to 25 years. The prevalent number of accidents resulting in injuries to this region took place in spring, especially between noon and 4 PM.

    Numerous guidelines to grade and manage sports-related concussions have been published. However, little is known about how frequently they are implemented in the emergency department. This study evaluates the current practices of emergency physicians (EPs) in managing sports-related concussions. To evaluate the current practice of EP evaluation and management of sports-related concussions. All EPs and emergency medicine residents in Kalamazoo County were surveyed regarding their management of sports-related concussions. The surveys obtained demographic data, participants' use of guidelines, and the importance of clinical and non-clinical factors in deciding when to allow a player to return to play. Of the 73 EP respondents, only 23% used a nationally recognized guideline, with no significant difference between attending and resident EPs. The symptomatic complaints of loss of consciousness, amnesia of the event, and difficulty concentrating were ranked most important by EPs in assessing patients with sports-related concussions. Among non-clinical factors, residents were significantly more likely than attendings to report that medical-legal, parental, and players' concerns were more likely to influence their decision in allowing a patient to return to play. EPs take into consideration important clinical factors in assessing patients with sports-related concussion. However, almost 75% do not use any nationally recognized guideline in their evaluation. Residents are more likely than attendings to be influenced by non-clinical factors. Copyright © 2011 Elsevier Inc. All rights reserved.

    Ballistic maxillofacial trauma in the UK is fortunately relatively rare, and generally involves low velocity handguns and shotguns. Civilian terrorist events have, however, shown that all maxillofacial surgeons need to understand how to treat injuries from improvised explosive devices. Maxillofacial surgeons in the UK have also been responsible for the management of soldiers evacuated from Iraq and Afghanistan, and in this review we describe the newer types of treatment that have evolved from these conflicts, particularly that of damage-control maxillofacial surgery.

    2013-01-01

    Full Text Available Myiasis is a rare disease primarily caused by the invasion of tissue by larvae of certain dipteran flies. Oral myiasis is still more "rare" and "unique" owing to the fact that oral cavity rarely provides the necessary habitat conducive for a larval lifecycle. Common predisposing factors are poor oral hygiene, halitosis, trauma, senility, learning disabilities, physically and mentally challenged conditions. Oral myiasis can lead to rapid tissue destruction and disfigurement and requires immediate treatment. Treatment consists of manual removal of maggots from the oral cavity after application of chemical agents. Good sanitation, personal and environmental hygiene and cleanliness and special care for debilitated persons are the best methods to prevent oral myiasis. This case report describes the presentation of oral myiasis caused by musca nebulo (common house fly in a 40-year-old male patient, with recent maxillofacial trauma. The patient was treated by manual removal larvae by topical application of turpentine oil, followed by surgical debridement of the wound and open reduction and internal fixation of the fracture.

    Full Text Available Introduction: Patients with maxillofacial trauma represent a major group of patients in plastic surgery practice. These traumas are often caused by in-car and noncar road accidents and can result in permanent damages. This study aims at providing an epidemiologic analysis of such cases together with their diagnostic procedures, treatment methods, and postoperative complications. Materials and Methods: A total of 1266 maxillofacial trauma cases that were operated on between 2003 and 2017 were studied, and analyzed for fractured bones, etiology, diagnosis and treatment principles, and complications. Results: The major etiologic factor causing maxillofacial trauma in our study is noncar road accidents (25.5%. Mandible fractures were seen to be the most common type of bone fracture (52.2%. Together with physical examination, computerized tomography and orthopantomography are the diagnostic procedures we effectively use in our clinic. Rigid and semi-rigid fixation with plate and screws are the most frequently used treatment methods, and complication rates are seen to be lower (by 6.6% than those reported in the literature. Conclusion: Careful and meticulous processes, as well as effective follow-up of the patient are required to achieve optimal esthetic and functional results in maxillofacial trauma cases. Such approach can help to reduce the possibility of complications and allow for their early identification, hence early intervention.

    Full Text Available In this paper the benefits of using additive manufacturing technologies in maxillofacial reconstruction are highlighted. Based on a real clinical case, the paper describes the manufacture of an implant prototype replacing the right zygomatic bone and a part of maxilla using additive manufacturing technologies. The face is the most expressive part of the human body that makes us unique. It was shown that the maxillofacial prostheses help to improve the psychological state of patients affected by, because low self esteem feeling appears commonly to this patients with the facial defects. The aim of this paper is to show how using additive manufacturing technologies methods within this research, the producing a surgical model will help surgeon to improve the pre-operative planning. For this we used additive manufacturing technologies such as Stereolitography to achieve the biomodel and FDM-fused deposition modelling to obtain a prototype model because these technologies make it possible to obtain prosthesis according to the physical and mechanical requirements of the region of implantation.

    Although injuries related to sports and recreation represent a significant burden to children and youth, few studies have examined the descriptive epidemiology of sports-related injury since 2005, and some sports such as ringette have not been evaluated to date. The primary purpose of this study was to provide the descriptive epidemiology of sports-related injuries treated in emergency departments for children and youth aged 5 - 19. A retrospective data analysis was performed using data from the Canadian Hospitals Injury Reporting and Prevention Program [CHIRPP] from fiscal years (April - March) 2007/08 to 2009/10. CHIRPP is a computerized information system designed by the Public Health Agency of Canada that collects information about injuries to people evaluated in emergency departments across 11 pediatric hospitals and 5 general hospitals in Canada. Thirteen sports or activities were analyzed (baseball, basketball, cycling, football, ice hockey, lacrosse, ringette, rugby, skiing, sledding, snowboarding, soccer, and volleyball). Descriptive statistics, including frequency by sport, age and sex, as well as the percent of concussions within each sport were calculated. Out of a total of 56, 691 reported sports and recreational injuries, soccer accounted for the largest proportion of injuries with 11,941 reported cases over the 3 year time period. Of these, approximately 30% were fractures. The 10 - 14 year age group reported the greatest proportion of injuries in 10 out of the 13 sports analyzed. In addition, males reported a greater number of overall injuries than females in 11 out of the 13 sports analyzed. The largest percentage of concussions was reported in ringette; these injuries accounted for 17.1% of overall injuries within this sport. Injury prevention programs in Canada should focus on improving evidence-based programs to reduce the burden of injuries in all sports.

    To conduct objective assessment of children with balance and vestibular complaints following sports-related concussions and identify the underlying deficits by analyzing laboratory test outcomes. Case series with chart review. Pediatric tertiary care facility. Medical records were reviewed of 42 pediatric patients with balance and/or vestibular complaints following sports-related concussions who underwent comprehensive laboratory testing on their balance and vestibular function. Patients' characteristics were summarized and results analyzed. More than 90% of the children with protracted dizziness or imbalance following sports-related concussion had at least 1 abnormal finding from the comprehensive balance and vestibular evaluation. The most frequent deficit was found in dynamic visual acuity test, followed by Sensory Organization Test and rotational test. Patient's balance problem associated with concussion seemed to be primarily instigated by vestibular dysfunction. Furthermore, semicircular canal dysfunction was involved more often than dysfunction of otolith organs. Yet, sports-related concussion. Vestibular impairment is common among children with protracted dizziness or imbalance following sports-related concussion. Our study demonstrated that proper and thorough evaluation is imperative to identify these underlying deficits and laboratory tests were helpful in the diagnosis and recommendation of following rehabilitations. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

  16. What are the real risks of sport-related concussion, and are they modifiable?

    2009-07-01

    Over the past two decades, the management of sport-related concussion has been the topic of increased attention in the scientific literature and in the popular media. Despite a proliferation of competing guidelines for concussion management, the widespread use of neuropsychological "baseline" testing designed to monitor postinjury recovery, and several prospective controlled studies of the natural history of concussion, there has been virtually no attempt to quantify the risks associated with sport-related concussion or to determine whether these risks are modifiable via management strategies. Using American football as a model, the short- and long-term risks of sport-related concussion are reviewed. It is concluded that serious short-term consequences of sport-related concussion are extremely rare and unlikely to be significantly modified via management strategies that rely on baseline testing. Other less serious short-term adverse outcomes are also quite rare, transient, and not likely to be altered by specific management guidelines. The long-term consequences of multiple sport-related head trauma remain unclear but are potentially of greater public health concern and should be the focus of increased research. Based on available evidence, there is little rationale for the use of rigid strategies or guidelines in the place of individual clinical decision-making in the management of these injuries.

    Nervus abducens is a pure motor nerve located in the pons. It retracts the eyeball laterally by stimulating rectus lateralis muscle. In case of their paralysis, diplopia and restriction in the eye movements while looking sideways, are seen. Since the same signs are seen due to the muscle entrapment in blowout fractures, its differential diagnosis has importance in terms of the treatment protocol and avoiding unnecessary operations. In this article, we present a 22-year-old male patient who was referred to our department due to the prediagnosis of blowout fracture following maxillofacial trauma. However, he was diagnosed with abducens nerve paralysis after the consultations and analysis and his restriction of movement was resolved via systemic steroid treatment instead of unnecessary operation.

    Patient-specific implant (PSI) is a personalized approach to reconstructive and esthetic surgery. This is particularly useful in maxillofacial surgery in which restoring the complex three-dimensional (3D) contour can be quite challenging. In certain situations, the best results can only be achieved with implants custom-made to fit a particular need. Significant progress has been made over the past decade in the design and manufacture of maxillofacial PSIs. Computer-aided design (CAD)/computer-aided manufacturing (CAM) technology is rapidly advancing and has provided new options for fabrication of PSIs with better precision. Maxillofacial PSIs can now be designed using preoperative imaging data as input into CAD software. The designed implant is then fabricated using a CAM technique such as 3D printing. This approach increases precision and decreases or completely eliminates the need for intraoperative modification of implants. The use of CAD/CAM-produced PSIs for maxillofacial reconstruction and augmentation can significantly improve contour outcomes and decrease operating time. CAD/CAM technology allows timely and precise fabrication of maxillofacial PSIs. This approach is gaining increasing popularity in maxillofacial reconstructive surgery. Continued advances in CAD technology and 3D printing are bound to improve the cost-effectiveness and decrease the production time of maxillofacial PSIs.

    In many health services communities the scope of oral and maxillofacial surgery (OMFS) as a discipline is frequently not probably understood. Good awareness towards OMFS among different branches of health services providers is essential for better referral strategies and will be for the benefit of the patient. The cross-sectional study was done using a specially prepared questionnaire distributed randomly to 125 general medical practitioners working in Jazan province. In this questionnaire, there were also some close-ended questions to evaluate awareness regarding a variety of conditions treated by the oral and maxillofacial surgeons. Out of 125 participants, 105 (84%) were aware of the oral and maxillofacial surgery as a speciality branch of dentistry. Only 52 (41.6%) participants were aware of the different treatment modalities coming under the scope of oral and maxillofacial surgery. Also in the referral of cases to the oral and maxillofacial surgeon, 50 (40%) participants referred their oral and maxillofacial region cases to OMS. Tooth removal was the only procedure where most of the medical practitioners knew it is a speciality procedure of the oral and maxillofacial surgeon. For facial fractures, 76 medical practitioners believe it comes under the scope of the orthopaedic surgeon. Similarly, for facial abscesses, 81 and 36 practitioners responded that it is a job of a general surgeon and OMS respectively. There is low awareness toward the scope of oral and maxillofacial surgery in the medical community. Knowledge and awareness of the scope of oral and maxillofacial surgery can improve the success and promptness of delivery of health services.

    At the dental clinic the infrared range radiation spectrum of tissues was used to study the dynamics of local temperature and structure of the skin, subcutaneous fat, and other tissues of the maxillofacial area in adult healthy volunteers and patients. In particular, we studied the dynamics of local temperature of mucous membranes of the mouth, teeth, and places in the mouth and dental structures in the norm and in various pathological conditions of the lips, gums, teeth, tongue, palate, and cheeks before, during and after chewing food, drinking water, medication, and inhalation of air. High safety and informational content of infrared thermography are prospective for the development of diagnostics in medicine. We have 3 new methods for infrared detection protected by patents in Russia.

    Maxillofacial injuries are among the commonest forms of body injuries. There are three divisions, namely, facial bone fractures, soft tissue injuries, and dentoalveolar injuries. Etiologies include motor vehicle accidents, assaults, falls, and sporting injuries. The aim of this study was to determine the profiles including the causes of maxillofacial injuries seen in an urban government hospital in the mainland of Penang State, Malaysia. This was a cross-sectional study that recruited cases reported within a period of 1 year. The source population was maxillofacial injury patients presenting to the Oral and Maxillofacial Surgery Department of an urban hospital in the Penang Mainland, North Malaysia between May 2007 and May 2008. Cases of patients involved in accidents that occurred outside the reference vicinity were excluded. A case report form was developed and completed by the attending clinicians. Data were analyzed using spss version 12.0. A total of 194 cases were studied, with the mean patient age being 27.8 (SD 15.20) years. The majority of patients were Malay men between 20 and 29 years of age. The main cause of injury was motorcycle accident (53.6%). The commonest injury (in isolation/combination with other injuries) involved the soft tissues (87.2%), dentoalveolar region (33.4%), and facial bones (23.9%). Laceration was the commonest soft tissue injury, and crown fracture was the most frequent dentoalveolar injury. The facial bone that was most highly involved in the injury was the zygoma. Subjects involved in motorcycle accidents had a significantly higher incidence of sustaining facial bone fractures. Motorcycle accidents were the commonest cause of maxillofacial injuries in the Penang Mainland, Malaysia. Most patients were young men. Hence, it is prudent to reinforce appropriate road safety and awareness interventions particularly focusing young male motorcyclists so as to reduce the risk of accidents. © 2011 John Wiley & Sons A/S.

    The aim of this study was to assess the incidence and patterns of work-related maxillofacial injuries, identifying worker categories with a high risk of injury. From a systematic computer-assisted database that has continuously recorded patients hospitalized with maxillofacial fractures, only patients with work-related injuries were considered. Occupation, mechanism of injury, and demographic and clinical data were analyzed. Work-related facial injuries represented the fifth most common cause of injury, with a percentage of 6.3 %. Maxillofacial fractures were most often seen in construction workers (37.9 %). The middle third was involved in 67 % of the cases; the mandible was the most frequently injured site. Work-related maxillofacial trauma is rare, but it is often complex and challenging as Facial Injury Severity Scale values show. In agreement with the few published reports, construction workers, together with farm and forestry workers, are at the highest risk of injuries, mainly because of struck by a thrown, projected, or falling object.

    Sport-related concussion affects athletes at every level of participation. The short and long-term effects of concussions that occur during childhood and adolescence are not fully understood. The purpose of this review is to describe the current burden of disease, current practice patterns and current recommendations for the assessment and management of sport-related concussions sustained by United States high school athletes. Millions of high school students participate in organized sports in the United States. Current estimates suggest that, across all sports, approximately 2.5 concussions occur for every 10 000 athletic exposures, in which an athletic exposure is defined as one athlete participating in one game or practice. At schools that employ at least one athletic trainer, most high school athletes who sustain sport-related concussions will be cared for by athletic trainers and primary care physicians. Approximately 40% will undergo computerized neurocognitive assessment. The number of high school athletes being diagnosed with sport-related concussions is rising. American football has the highest number of concussions in high school with girls' soccer having the second highest total number. Fortunately, coaches are becoming increasingly aware of these injuries and return-to-play guidelines are being implemented.

    Full Text Available Negative pressure wound therapy has greatly advanced the field of wound healing for nearly two decades, by providing a robust surgical adjunct technique for accelerating wound closure in acute and chronic wounds. However, the application of negative pressure wound therapy in maxillofacial applications has been relatively under utilized as a result of the physical articulations and contours of the head and neck that make it challenging to obtain an airtight seal for different negative pressure wound therapy systems. Adapting negative pressure wound therapies for maxillofacial applications could yield significant enhancement of wound closure in maxillofacial applications. The current review summarizes the basic science underlying negative pressure wound therapy, as well as specific maxillofacial procedures that could benefit from negative pressure wound therapy.

    OBJECTIVE Sports-related traumatic brain injury (TBI) is an important public health concern estimated to affect 300,000 to 3.8 million people annually in the United States. Although injuries to professional athletes dominate the media, this group represents only a small proportion of the overall population. Here, the authors characterize the demographics of sports-related TBI in adults from a community-based trauma population and identify predictors of prolonged hospitalization and increased morbidity and mortality rates. METHODS Utilizing the National Sample Program of the National Trauma Data Bank (NTDB), the authors retrospectively analyzed sports-related TBI data from adults (age ≥ 18 years) across 5 sporting categories-fall or interpersonal contact (FIC), roller sports, skiing/snowboarding, equestrian sports, and aquatic sports. Multivariable regression analysis was used to identify predictors of prolonged hospital length of stay (LOS), medical complications, inpatient mortality rates, and hospital discharge disposition. Statistical significance was assessed at α sports-related TBIs were documented in the NTDB, which represented 18,310 incidents nationally. Equestrian sports were the greatest contributors to sports-related TBI (45.2%). Mild TBI represented nearly 86% of injuries overall. Mean (± SEM) LOSs in the hospital or intensive care unit (ICU) were 4.25 ± 0.09 days and 1.60 ± 0.06 days, respectively. The mortality rate was 3.0% across all patients, but was statistically higher in TBI from roller sports (4.1%) and aquatic sports (7.7%). Age, hypotension on admission to the emergency department (ED), and the severity of head and extracranial injuries were statistically significant predictors of prolonged hospital and ICU LOSs, medical complications, failure to discharge to home, and death. Traumatic brain injury during aquatic sports was similarly associated with prolonged ICU and hospital LOSs, medical complications, and failure to be discharged to

    Full Text Available In Recent studies underline the fact that adolescents are, at many times, likely to experience serious communication problems with their families and close environments. So, the aim of this study is to determine positive impact of sport-related games, which are performed as extracurricular activities, on high school students’ communication skills. In the study, pre, & post-tests was utilized with the control group’s experimental patterns. Two participant groups were made up of totally 30 high school students, 15 of whom would be in the experimental group and the rest of whom were in the control group. The former group was given sport- related 20 applications for 10 weeks during which the latter group would not deal with any extracurricular activities. Meanwhile, before and after the applications, data was collected by means of “The Communication Skills Scale” which was developed by Korkut (1996 and then analysed through “two-way ANCOVA” test techniques. Results clarify that the considerable gap in scores of the students’ pre, & post-tests perception concerning their communication skills are clearly attributed to sport-related games and it was also established that scores of the students in the experimental group were meaningfully higher than ones in the control group. However, perception of communication skills in the both groups was not significantly different by sex of the students. Moreover, the common effect of sex and participation on sport- related games was not found statistically meaningful in terms of communication skills. Consequently, it could be said that sport-related games impact positively communication skills.

To describe the medical providers and medical studies used when assessing sport-related concussions. To determine the effects of medical provider type on timing of return to play, frequency of imaging, and frequency of neuropsychological testing. Descriptive epidemiology study. All concussions recorded by the High School Reporting Information Online (HS RIO) injury surveillance system during the 2009 to 2010 academic year were included. χ(2) analyses were conducted for categorical variables. Fisher exact test was used for nonparametric data. Logistic regression analyses were used when adjusting for potential confounders. Statistical significance was considered for P sport-related concussions, representing 14.6% of all injuries. Most (94.4%) concussions were assessed by athletic trainers (ATs), 58.8% by a primary care physician. Few concussions were managed by specialists. The assessment of 21.2% included computed tomography. Computerized neuropsychological testing was used for 41.2%. For 50.1%, a physician decided when to return the athlete to play; for 46.2%, the decision was made by an AT. After adjusting for potential confounders, no associations between timing of return to play and the type of provider (physician vs AT) deciding to return the athlete to play were found. Concussions account for nearly 15% of all sport-related injuries in high school athletes. The timing of return to play after a sport-related concussion is similar regardless of whether the decision to return the athlete to play is made by a physician or an AT. When a medical doctor is involved, most concussions are assessed by primary care physicians as opposed to subspecialists. Computed tomography is obtained during the assessment of 1 of every 5 concussions occurring in high school athletes.

    Pediatric spinal cord injury (PSCI) is a devastating injury that can cause significant long-term consequences. The purpose of this study is to calculate and report the prevalence of PSCI, identify risk factors for sports-related PSCI, and evaluate associated factors. The data sets of the Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database (KID) from 2000-2012 were analyzed using ICD-9-CM external cause of injury codes to identify the mechanism of injury contributing to PSCI hospitalization. We then extracted demographic data on each admission including age, gender, race, and year of admission. We further stratified the data by sports-related cases of injury. Multivariate logistic regression analyses were used to identify independent risk factors. Of our study population, 0.8% had a documented diagnosis of spinal cord injury (SCI). The most common documented external cause of injury code was motor vehicle accidents, representing roughly half of all cases in patients 0-9 years-old (p = 0.001). PSCI due to sports as an external cause of injury was more prevalent in patients 10-17 years old, and was especially prevalent in the 10-13 year-old age category in which sports-related PSCI reached a high of 25.6%. Risk factors for traumatic PSCI after a sports-related external cause included being of older age, male, and white. The prevalence of SCI increased with age. Given the popularity of youth sports in the United States, parents and sports officials should be aware of the increased risk of sports-related PSCI among patients 10-17 years old. Level III, retrospective cohort study.

    This study evaluated the prevalence of isolated tympanic fractures and their correlation with mandibular fractures by using maxillofacial computed tomography (CT). We retrospectively evaluated the maxillofacial CT of 1590 patients who presented to our emergency department with maxillofacial trauma between December 2010 and December 2012. Maxillofacial CT was used as the criterion standard for evaluating patients with maxillofacial fractures. The CT images were evaluated by using an electronic picture archiving and communications system and interpreted independently by 2 radiologists. The maxillofacial CT images revealed mandibular fractures in 167 of the patients and isolated tympanic plate fractures in 35 of these 167 patients. Four patients (11%) had a bilateral tympanic plate fracture, and 31 patients (89%) had unilateral tympanic plate fracture. Of all the tympanic plate fractures, 19 (54%) were on the right side and 16 (46%) were on the left side (P > .05). In our results, a significant correlation between the presence of a right-sided tympanic plate fracture and fracture of the ipsilateral condylar process was found (P = .036). However, a statistically significant difference between the presence of a tympanic plate fracture and other mandible fractures, additional soft-tissue findings, or the number of fractures was not determined (P > .05). Sex had no impact on the presence of tympanic plate fracture (P > .05). The frequency of isolated tympanic plate fractures in maxillofacial trauma is low, but it is an important anatomic location. Condyle fractures are significantly associated with isolated tympanic plate fractures. The presence of these injuries should raise suspicion of a concomitant isolated tympanic plate fracture.

    The author has studied maxillo-facial anatomical landmarks using Status X with two methods. The one has performed by application of contrast media on the human dry skull, the other has performed on living human skull as control group. Comparing the panagraphs taken by two methods, the author has drawn following results: 1. The panagraphs revealed the undistorted highly sharp panoramic shadows of each jaw on a film. 2. Diminishing the inserted anode tube to 4 cm (focal incisor distance 3 cm), overlapping-free representation of the in terdental spaces of the premolars and anterior teeth was taken. 3. Alternating the head position of the objects, direction of anode tube and film placing, the shadows of temporomandibular joint and zygomatic arch were taken without overlapping the other bone tissues. 4. In the panagraphs applied various shaped contrast media to each anatomical landmark, a radio-anatomical atlas which is necessary to interpret various bone tissues was taken. 5. In order to interpret panagraphic shadows easily, the author has tried this study by comparing the films of the living human skull with the films of the human dry skull applied contrast media.

    In this study seventeen patients with neurofibromatosis in the maxillofacial region were presented. There was no great difference in the incidence of the disease between males and females. The patient age range was 1 to 75 years with a mean age of 21.5 years. Family history was positive in 5 cases. The spectrum of the clinical manifestations of this disease, known for its protean characteristics, were evident in all of our 17 patients. 14 (82.4%) patients had cafeau-lait spots; 3 (1 7.6%) had multiple cutaneous nodules; malignant transformation was documented in only one case (5.9%). Psychologic depression was recorded in 2 (11.8%) ceases, and one(5.9%) case had grand-mal epilepsy. A rare location of neurofibromatous nodules, i.e. in eye (iris nodules), was reported in only one (5.9%) case. The most frequently performed procedure in our cases was excision of the tumor mass which was, in most instances, incomplete. However, massive bleeding during surgical intervention was prominent in four cases and was overcome with extensive packing removed after approximately two weeks. An interesting finding in this study was the incidence of radiologic findings which was higher (76.4%) than previously reported. All cases of this study were unilateral and involvement of the mandible (65%) was more than that of the maxillae. (author)

  15. Delayed Presentation of Isolated Complete Pancreatic Transection as a Result of Sport-Related Blunt Trauma to the Abdomen

    Andrew J. Healey

    2008-01-01

    Full Text Available Introduction: Blunt abdominal trauma is a rare but well-recognized cause of pancreatic transection. A delayed presentation of pancreatic fracture following sport-related blunt trauma with the coexisting diagnostic pitfalls is presented. Case Report: A 17-year-old rugby player was referred to our specialist unit after having been diagnosed with traumatic pancreatic transection, having presented 24 h after a sporting injury. Despite haemodynamic stability, at laparotomy he was found to have a diffuse mesenteric hematoma involving the large and small bowel mesentery, extending down to the sigmoid colon from the splenic flexure, and a large retroperitoneal hematoma arising from the pancreas. The pancreas was completely severed with the superior border of the distal segment remaining attached to the splenic vein that was intact. A distal pancreatectomy with spleen preservation and evacuation of the retroperitoneal hematoma was performed. Discussion/Conclusion: Blunt pancreatic trauma is a serious condition. Diagnosis and treatment may often be delayed, which in turn may drastically increase morbidity and mortality. Diagnostic difficulties apply to both paraclinical and radiological diagnostic methods. A high index of suspicion should be maintained in such cases, with a multi-modality diagnostic approach and prompt surgical intervention as required.

    OBJECTIVE Traumatic brain injury (TBI) in children is a significant public health concern estimated to result in over 500,000 emergency department (ED) visits and more than 60,000 hospitalizations in the United States annually. Sports activities are one important mechanism leading to pediatric TBI. In this study, the authors characterize the demographics of sports-related TBI in the pediatric population and identify predictors of prolonged hospitalization and of increased morbidity and mortality rates. METHODS Utilizing the National Sample Program of the National Trauma Data Bank (NTDB), the authors retrospectively analyzed sports-related TBI data from children (age 0-17 years) across 5 sports categories: fall or interpersonal contact (FIC), roller sports, skiing/snowboarding, equestrian sports, and aquatic sports. Multivariable regression analysis was used to identify predictors of prolonged length of stay (LOS) in the hospital or intensive care unit (ICU), medical complications, inpatient mortality rates, and hospital discharge disposition. Statistical significance was assessed at α sports-related TBIs were recorded in the NTDB, and these injuries represented 11,614 incidents nationally after sample weighting. Fall or interpersonal contact events were the greatest contributors to sports-related TBI (47.4%). Mild TBI represented 87.1% of the injuries overall. Mean (± SEM) LOSs in the hospital and ICU were 2.68 ± 0.07 days and 2.73 ± 0.12 days, respectively. The overall mortality rate was 0.8%, and the prevalence of medical complications was 2.1% across all patients. Severities of head and extracranial injuries were significant predictors of prolonged hospital and ICU LOSs, medical complications, failure to discharge to home, and death. Hypotension on admission to the ED was a significant predictor of failure to discharge to home (OR 0.05, 95% CI 0.03-0.07, p sports was independently associated with prolonged hospital LOS compared with FIC events (mean increase

    Osseointegrated implants have begun to be used not only in general practice in dentistry but also in various clinical situations in the maxillofacial region. The process has yielded three problems: the spread of application, new materials and diagnostic methods, and management for difficult situations. This paper presents basic data and clinical guidelines for new applications, it investigates the characteristics of the materials and the usefulness of a new diagnostic method, and it studies effective techniques for difficult cases. The results obtained are as follows: Investigations into the spreading application. The lateral and superior orbital rim have sufficient bone thickness and width for the implant body to be placed. Osseointegrated implants, especially by the fixed bridge technique, are not recommended in the craniofacial bone and jaws of young children. Implant placement into bone after/before irradiation must be performed in consideration of impaired osteogenesis, the decrease of trabecular bone, and the time interval between implantation and irradiation. Investigations into materials and diagnostic methods. Hydroxyapatite-coated and titanium implants should be selected according to the characteristics of the materials. A dental simulating soft may also be applicable in the craniofacial region. Investigations into the management of difficult cases. Hyperbaric oxygen therapy (HBO), bone morphogenetic protein (BMP), and tissue engineering should be useful for improving the quality and increasing the quantity of bone where implants are placed. Soft tissue around implants placed in the reconstructed area should be replaced with mucosal tissue. The data obtained here should be useful for increasing the efficiency of osseointegrated implants, but further basic research is required in the future. (author)

    This study reviewed the current state of maxillofacial rehabilitation in resource-limited nations. A rigorous literature review was undertaken using several technical and clinical databases using a variety of key words pertinent to maxillofacial prosthetic rehabilitation and resource-limited areas. In addition, interviews were conducted with researchers, clinicians and prosthetists that had direct experience of volunteering or working in resource-limited countries. Results from the review and interviews suggest rehabilitating patients in resource-limited countries remains challenging and efforts to improve the situation requires a multifactorial approach. In conclusion, public health awareness programmes to reduce the causation of injuries and bespoke maxillofacial prosthetics training programmes to suit these countries, as opposed to attempting to replicate Western training programmes. It is also possible that usage of locally sourced and cheaper materials and the use of low-cost technologies could greatly improve maxillofacial rehabilitation efforts in these localities. Implications for Rehabilitation More information and support needs to be provided to maxillofacial defect/injuries patients and to their families or guardians in a culturally sensitive manner by governments. The health needs, economic and psychological needs of the patients need to be taken into account during the rehabilitation process by clinicians and healthcare organizations. The possibility of developing training programs to suit these resource limited countries and not necessarily follow conventional fabrication methods must be looked into further by educational entities.

    Background Little existing data describe which medical professionals and which medical studies are used to assess sport-related concussions in high school athletes. Purpose To describe the medical providers and medical studies used when assessing sport-related concussions. To determine the effects of medical provider type on timing of return to play, frequency of imaging, and frequency of neuropsychological testing. Study Design Descriptive epidemiology study. Methods All concussions recorded by the High School Reporting Information Online (HS RIO) injury surveillance system during the 2009 to 2010 academic year were included. χ2 analyses were conducted for categorical variables. Fisher exact test was used for nonparametric data. Logistic regression analyses were used when adjusting for potential confounders. Statistical significance was considered for P concussions, representing 14.6% of all injuries. Most (94.4%) concussions were assessed by athletic trainers (ATs), 58.8% by a primary care physician. Few concussions were managed by specialists. The assessment of 21.2% included computed tomography. Computerized neuropsychological testing was used for 41.2%. For 50.1%, a physician decided when to return the athlete to play; for 46.2%, the decision was made by an AT. After adjusting for potential confounders, no associations between timing of return to play and the type of provider (physician vs AT) deciding to return the athlete to play were found. Conclusion Concussions account for nearly 15% of all sport-related injuries in high school athletes. The timing of return to play after a sport-related concussion is similar regardless of whether the decision to return the athlete to play is made by a physician or an AT. When a medical doctor is involved, most concussions are assessed by primary care physicians as opposed to subspecialists. Computed tomography is obtained during the assessment of 1 of every 5 concussions occurring in high school athletes. PMID:21969181

    Sport-related mild traumatic brain injury (mTBI) or concussion is a significant health concern to athletes with potential long-term consequences. The diagnosis of sport concussion and return to sport decision making is one of the greatest challenges facing health care clinicians working in sports. Blood biomarkers have recently demonstrated their potential in assisting the detection of brain injury particularly, in those cases with no obvious physical injury. We have recently discovered plasma soluble cellular prion protein (PrP(C)) as a potential reliable biomarker for blast induced TBI (bTBI) in a rodent animal model. In order to explore the application of this novel TBI biomarker to sport-related concussion, we conducted a pilot study at the University of Saskatchewan (U of S) by recruiting athlete and non-athlete 18 to 30 year-old students. Using a modified quantitative ELISA method, we first established normal values for the plasma soluble PrP(C) in male and female students. The measured plasma soluble PrP(C) in confirmed concussion cases demonstrated a significant elevation of this analyte in post-concussion samples. Data collected from our pilot study indicates that the plasma soluble PrP(C) is a potential biomarker for sport-related concussion, which may be further developed into a clinical diagnostic tool to assist clinicians in the assessment of sport concussion and return-to-play decision making.

    To identify differences and gaps in recommendations to patients for the management of sport-related concussion among FPs, emergency department physicians (EDPs), and pediatricians. A self-administered, multiple-choice survey was e-mailed to FPs, EDPs, and pediatricians. The survey had been assessed for content validity. Two community teaching hospitals in the greater Toronto area in Ontario. Two hundred seventy physicians, including FPs, EDPs, and pediatricians, were invited to participate. Identification of sources of concussion management information, usefulness of concussion diagnosis strategies, and whether physicians use common terminology when explaining cognitive rest strategies to patients after sport-related concussions. The response rate was 43.7%. Surveys were completed by 70 FPs, 23 EDPs, and 11 pediatricians. In total, 49% of FP, 52% of EDP, and 27% of pediatrician respondents reported no knowledge of any consensus statements on concussion in sport, and 54% of FPs, 86% of EDPs, and 78% of pediatricians never used the Sport Concussion Assessment Tool, version 2. Only 49% of FPs, 57% of EDPs, and 36% of pediatricians always advised cognitive rest. This study identified large gaps in the knowledge of concussion guidelines and implementation of recommendations for treating patients with sport-related concussions. Although some physicians recommended physical and cognitive rest, a large proportion failed to consistently advise this strategy. Better knowledge transfer efforts should target all 3 groups of physicians. Copyright© the College of Family Physicians of Canada.

    Full Text Available Sport-related mild traumatic brain injury (mTBI or concussion is a significant health concern to athletes with potential long-term consequences. The diagnosis of sport concussion and return to sport decision making is one of the greatest challenges facing health care clinicians working in sports. Blood biomarkers have recently demonstrated their potential in assisting the detection of brain injury particularly, in those cases with no obvious physical injury. We have recently discovered plasma soluble cellular prion protein (PrP(C as a potential reliable biomarker for blast induced TBI (bTBI in a rodent animal model. In order to explore the application of this novel TBI biomarker to sport-related concussion, we conducted a pilot study at the University of Saskatchewan (U of S by recruiting athlete and non-athlete 18 to 30 year-old students. Using a modified quantitative ELISA method, we first established normal values for the plasma soluble PrP(C in male and female students. The measured plasma soluble PrP(C in confirmed concussion cases demonstrated a significant elevation of this analyte in post-concussion samples. Data collected from our pilot study indicates that the plasma soluble PrP(C is a potential biomarker for sport-related concussion, which may be further developed into a clinical diagnostic tool to assist clinicians in the assessment of sport concussion and return-to-play decision making.

    Oral and maxillofacial surgeons must constantly weigh the risks of surgical intervention for pediatric mandible fractures against the wonderful healing capacity of children. The majority of pediatric mandibular fractures can be managed with closed techniques using short periods of maxillomandibular fixation or training elastics alone. Generally, the use of plate- and screw-type internal fixation is reserved for difficult fractures. This article details general and special considerations for this surgery including: craniofacial growth & development, surgical anatomy, epidemiology evaluation, various fractures, the role rigid internal fixation and the Risdon cable in pediatric maxillofacial trauma. It concludes with suggestions concerning long-term follow-up care in light of the mobility, insurance obstacles, and family dynamics facing the patient population.

    Regenerative nanotechnology is at the forefront of medical research, and translational medicine is a challenge to both scientists and clinicians. Although there has been an exponential rise in the volume of research generated about it for both medical and surgical uses, key questions remain about its actual benefits. Nevertheless, some people think that therapeutics based on its principles may form the core of applied research for the future. Here we give an account of its current use in oral and maxillofacial surgery, and implications and challenges for the future.

    The question of whether or not a patient has consented to treatment has recently become significant to all who practise oral and maxillofacial surgery. It is often linked to professional negligence when the outcome differs from the patient's perception or expectation of the operation. Consent may be oral or written, applies to referred patients and all those with physical and mental handicap and religious restrictions. Examples of procedure in discussing consent assist the surgeon to inform without creating fear. Knowledge of the benefits of informed consent and current legal opinion assist the oral and maxillofacial surgeon to avoid the pitfalls of failure to inform.

    Obturators and facial prostheses are important not only in rehabilitation and aesthetics, but also in patient re-socialisation. The level of reintegration is directly related to the degree of satisfaction with rehabilitation. So, the maxillofacial prosthetics must provide patient satisfaction during treatment. This study aimed to search information in database and conduct a literature review on patient satisfaction with maxillofacial prosthesis. The problems experienced by these patients may decrease when specialists keep the patient on regular inspection. Rehabilitation through alloplasty or prosthetic restoration provides satisfactory conditions in aesthetics and well-being and reinstates individuals in familial and social environment.

    Full Text Available Background: Airway management in maxillofacial injuries presents with a unique set of problems. Compromised airway is still a challenge to the anesthesiologist in spite of all modalities available. Maxillofacial injuries are the result of high-velocity trauma arising from road traffic accidents, sport injuries, falls and gunshot wounds. Any flaw in airway management may lead to grave morbidity and mortality in prehospital or hospital settings and as well as for reconstruction of fractures subsequently. Methods: One hundred and seventy-seven patients of maxillofacial injuries, operated over a period of one and half years during July 2008 to December 2009 in Al-Nahdha hospital were reviewed. All patients were reviewed in depth with age related type of injury, etiology and techniques of difficult airway management. Results: The major etiology of injuries were road traffic accidents (67% followed by sport (15% and fall (15%. Majority of patients were young in the age group of 11-30 years (71 %. Fracture mandible (53% was the most common injury, followed by fracture maxilla (21%, fracture zygoma (19% and pan-facial fractures (6%. Maxillofacial injuries compromise mask ventilation and difficult airway due to facial fractures, tissue edema and deranged anatomy. Shared airway with the surgeon needs special attention due to restrictions imposed during surgery. Several methods available for securing the airway, both decision-making and performance, are important in such circumstances. Airway secured by nasal intubation with direct visualization of vocal cords was the most common (57%, followed by oral intubation (17%. Other methods like tracheostomy and blind nasal intubation was avoided by fiberoptic bronchoscopic nasal intubation in 26% of patients. Conclusion: The results of this study indicated that surgically securing the airway by tracheostomy should be revised compared to other available methods. In the era of rigid fixation of fractures and the

    The purpose of this study was to evaluate the diagnostic efficacy of panoramic radiographs for detection of mandibular fractures. The sample was comprised of 65 patients (55 fractured, 10 non-fractured) with 92 fracture sites confirmed by multi-detector computed tomography (CT). Panoramic radiographs were evaluated for mandibular fractures by six examiners; two oral and maxillofacial radiologists (observer A and B), two oral and maxillofacial surgeons (observer C and D), and two general dentists (observer E and F). Sensitivity of panoramic radiography for mandibular fractures was 95.7% in observer A and B, 93.5% in observer C and D and 80.4% in observer E and F. The lowest sensitivity was shown in symphyseal/parasymphyseal areas, followed by subcondylar/condylar regions. Panoramic radiography is adequate for detection of mandibular fractures. However, additional multidetector CT is recommended to ascertain some indecisive fractures of symphysis and condyle, and in complicated fractures.

    To identify the causes of sports-related eye and adnexal injuries in children in Perth, Western Australia, to determine which sporting activities pose the highest risk of eye and adnexal injury to children. We performed a 12-year retrospective review of children admitted to hospital from 2002 to 2013 with sports-related ocular and adnexal eye injuries. The main outcome measures were the cause and type of ocular and adnexal injuries, age and gender risk factors. A total of 93 cases of sports-related ocular and adnexal injury were identified in the 12-year time period. A peak in injuries occurred for 12- to 14-year-olds with a second peak in 6- to 8-year-olds; the median age was 8.82 years (range = 1.59-16.47). Cycling, football (including soccer and Australian Rules Football), tennis, trampolining, fishing and swimming were the sports responsible for the greatest number of injuries, a total of 63%. More than one-third (35%) of injuries resulted from being struck by a blunt object, and more than a quarter (26%) were as a result of contact with a blunt projectile. Serious ocular and adnexal injuries have occurred in children as a result of participating in sports, with cycling and football being the largest contributors in the 12-year period we assessed. As we continue to encourage children to spend more time participating in sports and recreational activities, identifying associated risk factors will help us develop injury prevention strategies to promote eye safety for children. © 2015 Acta Ophthalmologica Scandinavica Foundation.

    The risk of sport-related concussion (SRC) has emerged as a major public health concern. In rare instances, sport-related head injuries can be even more severe, such as subdural hemorrhage, epidural hemorrhage, or malignant cerebral edema. Unlike SRCs, sport-related structural brain injury (SRSBI) is rare, may require neurosurgical intervention, and can lead to permanent neurologic deficit or death. Data characterizing SRSBI are limited, and many have recognized the need to better understand these catastrophic brain injuries. The goal of the current series is to describe, in detail, the presentation, management, and outcomes of examples of these rare injuries. During the fall of 2015, three high school football players presented with acute subdural hemorrhages following in-game collisions and were treated at our institution within a span of 2 months. For the 2 athletes who required surgical intervention, a previous SRC was sustained within 4 weeks before the catastrophic event. One year after injury, 2 players have returned to school, though with persistent deficits. One patient remains nonverbal and wheelchair bound. None of the athletes has returned to sports. Acute subdural hemorrhage resultant from an in-game football collision is rare. The temporal proximity of the reported SRSBIs to recent SRCs emphasizes the importance of return-to-play protocols and raises questions regarding the possibility of second impact syndrome. Although epidemiologic conclusions cannot be drawn from this small sample, these cases provide a unique opportunity to demonstrate the presentation, management, and long-term outcomes of SRSBI in American high school football.

    We quantified the length of recovery time by week in a cohort of pediatric sports-related concussion patients treated at concussion clinics, and examined patient and injury characteristics associated with prolonged recovery. A retrospective, cohort design. Seven concussion clinics at a Midwest children's hospital. Patients aged 10 to 17 years with a diagnosed sports-related concussion presenting to the clinic within 30 days of injury. Length of recovery by week. Unadjusted and adjusted multinomial logistic regression analyses were used to model the effect of patient and injury characteristics on length of recovery by week. Median length of recovery was 17 days. Only 16.3% (299/1840) of patients recovered within one week, whereas 26.4% took longer than four weeks to recover. By 2 months postinjury, 6.7% of patients were still experiencing symptoms. Higher symptom scores at injury and initial visit were significantly associated with prolonged symptoms by week. Patients who presented to the clinic more than 2 weeks postinjury or who had 2 or more previous concussions showed increased risk for prolonged recovery. Females were at greater risk for prolonged recovery than males (odds ratio = 2.08, 95% confidence interval = 1.49-2.89). Age was not significantly associated with recovery length. High symptom scores at injury and initial visit, time to initial clinical presentation, presence of 2 or more previous concussions, and female sex are associated with prolonged concussion recovery. Further research should aim to establish objective measures of recovery, accounting for treatment received during the recovery. The median length of recovery is 17 days among pediatric sports-related concussion patients treated at concussion clinics. Only 16.3% of patients recovered within one week, whereas 26.4% took longer than 4 weeks to recover.

    Full Text Available Nowadays, sport injuries constitute a major part of social accidents. The aim of the presentstudy, was to investigate the frequency of maxillofacial injuries among athletes-members of differentsports federations in Iran from 1998-2001. For this reason files which was related to sport injuries of men and women athletes-members of sports federations were studied in Medical Federation of the Islamic Republic of Iran Sports Organization. The information were received through 26 medical organizations,located in different states of the country. The results showed that maxillofacial injuries constitute the major part of the sports injuries. In male athletes, football was the most important cause for maxillofacial injuries. However, mountain climbing and skiing play the least role in this field. Among female athletes,karate was the cause of the highest rate of maxillofacial sport injuries. Diving, mountain climbing and skiing cause the least number of maxillofacial accidents. Nasal fracture was the most common sport injury among Iraninan male and female athletes.

    Sports-related injuries of the lower extremity are frequent. Before magnetic resonance (MR) imaging was available, ultrasound, radionuclide scintigraphy and computed tomography were used to evaluate muscle trauma. Although relatively inexpensive, these imaging modalities are limited by their low specificity. The high degree of soft tissue contrast and multiplanar capability of MR imaging, allow direct visualization as well as characterization of traumatic muscle lesions. This pictorial review highlights the spectrum of traumatic muscle lesions on MRI, with emphasis on its typical appearances. (orig.)

    Full Text Available Deep vein thrombosis (DVT is caused by obstruction of blood flow of deep veins in upper and lower limb. One of the precipitating factors for DVT is surgery under general anesthesia exceeding 30 min. However, there are very few reports of DVT associated with surgery of oral and maxillofacial region. In this paper we report two cases of DVT involving left ilio-femoropopliteal deep vein in one patient treated for fractured left angle of mandible and left peroneal vein in the other patient treated for oral sub mucous fibrosis. Clinical and color Doppler examination were performed to diagnose the condition and were referred to vascular surgical unit of higher institute for further management. These cases illustrates any surgery of maxillofacial region is not free from risk of DVT, which can cause fatal pulmonary thromboembolism.

    fracture repair. Almost all the dental classes believed that the specialty of OMS was both medical and dental in nature and that it is a very important dental specialty. Dental student perceptions of OMS change throughout their undergraduate training. The reasons for such a change are multivariate and might include factors such as the amount of didactic training and clinical exposure. It is vital to both recognize and address this change at an undergraduate level of training in an effort to increase educated referrals to a surgeon who might provide the best treatment options for the patient. A stronger understanding of the dental students' perception of OMS provides an opportunity for the oral and maxillofacial academic faculty to better educate students and, ultimately, strengthen our specialty.

    2017-10-01

    Concussion is one of the most common injuries in athletes. Current concussion consensus statements propose that female sex may be a modifying factor in concussion management and recovery. To determine whether female athletes in middle school and high school with a first-time, sports-related concussion remained symptomatic longer than their male counterparts. A retrospective medical record analysis was performed among athletes who sustained a concussion between 2011 and 2013. Inclusion criteria consisted of age between 11 and 18 years and diagnosis of first-time concussion sustained while playing organized sports. Using the documented notes in the medical record, length of time that each athlete was symptomatic from his or her concussion was calculated. A total of 110 male and 102 female athletes (N=212) met the eligibility criteria for the study. A significant difference was found in the median number of days female athletes remained symptomatic (28 days) when compared with male athletes (11 days) (Psports played. Female athletes aged 11 to 18 years with first-time, sports-related concussions remained symptomatic for a longer period when compared with male athletes of similar age, regardless of sport played. The mechanism behind this difference needs to be further elucidated.

    Despite the recognition of sports as a significant contributor in the etiology of spinal cord injury (SCI), no studies have systematically explored the epidemiology of SCI caused by sports. This paper aims to give a systematic overview of the epidemiology of sport-related spinal cord injury around the world. A systematic review was conducted to identify published literature reporting the epidemiology of SCI caused by sports. The literature search was conducted in MEDLINE/PubMed, CINAHL, EMBASE, PsycINFO and Sportdiscus with date limits 1980 through to July 2015. Data from 54 studies covering 25 countries was extracted and collated. Important findings include identification of 6 countries in which sports accounts for over 13% of SCI (highest to lowest: Russia, Fiji, New Zealand, Iceland, France and Canada); individual sports with high risk for SCI (diving, skiing, rugby, and horseback riding); and the most common level of injury for various sports (almost entirely cervical for hockey, skiing, diving and American football, while over half of horseback riding and snowboarding injuries are thoracic or lumbosacral). This paper identifies countries and sports with higher rates of sport-related SCIs where implementation of prevention programs and reporting systems to track SCI epidemiology may be helpful, and highlights gaps in our current knowledge for further investigation. The comparison of SCI occurrence for each sport across countries, as well as examination of the specific characteristics of SCI incurred for individual sports will assist in directing efforts for prevention.

    OBJECTIVE Arachnoid cysts (ACs) are congenital lesions bordered by an arachnoid membrane. Researchers have postulated that individuals with an AC demonstrate a higher rate of structural brain injury after trauma. Given the potential neurological consequences of a structural brain injury requiring neurosurgical intervention, the authors sought to perform a systematic review of sport-related structural-brain injury associated with ACs with a corresponding quantitative analysis. METHODS Titles and abstracts were searched systematically across the following databases: PubMed, Embase, CINAHL, and PsycINFO. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed case reports, case series, or observational studies that reported a structural brain injury due to a sport or recreational activity (hereafter referred to as sport-related) with an associated AC were included. Patients were excluded if they did not have an AC, suffered a concussion without structural brain injury, or sustained the injury during a non-sport-related activity (e.g., fall, motor vehicle collision). Descriptive statistical analysis and time to presentation data were summarized. Univariate logistic regression models to assess predictors of neurological deficit, open craniotomy, and cystoperitoneal shunt were completed. RESULTS After an initial search of 994 original articles, 52 studies were found that reported 65 cases of sport-related structural brain injury associated with an AC. The median age at presentation was 16 years (range 4-75 years). Headache was the most common presenting symptom (98%), followed by nausea and vomiting in 49%. Thirteen patients (21%) presented with a neurological deficit, most commonly hemiparesis. Open craniotomy was the most common form of treatment (49%). Bur holes and cyst fenestration were performed in 29 (45%) and 31 (48%) patients, respectively. Seven patients (11%) received

    The ratio of male and female patients during the study period did not change (men 89%, women — 11 %. Single fractures that do not require surgical treatment were dominated. Operating activities during the study period of fracture increased. For 5 years, the number of complications of traumatic injuries remained the same. Conclusion. Statistical analysis of traumatic injuries of the maxillofacial region shows that the average age of the patients decreased by almost 5 years, reduced average hospital stay. Most of the patients were admitted to the profile department in the early period (up to 3 days after preparation, but 21.6% of the patients were received only with the development of complications. The article concludes that there is a need to find new methods of diagnosis, treatment and prevention of complications of traumatic injuries.

    2017-09-18

    Approximately 1.6 to 3.8 million recreational and sports-related concussions (SRC) occur each year in the Unites States. Research suggest that female athletes are at a greater risk for a SRC compared to male athletes competing in comparable sports (i.e., soccer, basketball). Moreover, female athletes have reported more total symptoms and greater neurocognitive impairments following a SRC. Female athletes have been found to report greater symptom provocation as measured by the Vestibular/Ocular Motor Screening (VOMS), and increased brain activation compared to males. There is a scarcity of research on long-term effects of SRC in male and female athletes. Therefore, the aim of this review article is to summarize the existing literature on sex differences in acute and sub-acute SRC outcomes. Copyright © 2017. Published by Elsevier B.V.

    The decision to advise an athlete to retire from sports following sports-related concussion (SRC) remains a persistent challenge for physicians. In the absence of strong empirical evidence to support recommendations, clinical decision making must be individualized and should involve a multidisciplinary team of experts in concussion and traumatic brain injury. Although previous authors have advocated for a more conservative approach to these issues in child and adolescent athletes, there are few reports outlining considerations for this process among this unique population. Here, the authors use multiple case illustrations to discuss 3 subgroups of clinical considerations for sports retirement among pediatric SRC patients including the following: those with structural brain abnormalities identified on neuroimaging, those presenting with focal neurological deficits and abnormalities on physical examination, and those in whom the cumulative or prolonged effects of concussion are suspected or demonstrated. The authors' evolving multidisciplinary institutional approach to return-to-play and retirement decision making in pediatric SRC is also presented.

    This report based on 300 cases of serious diseases in maxillofacial region by radiograms seen at the department of dental radiodontics, infirmary school of dentistry, Kyung Hee University from October 1971 to August 1974. The maxillofacial diseases were analysed upon the following items, such as 1) the frequency of dominant diseases, 2) sex-ratio of male to female, 3) predominant region of diseases, 4) comparison with the age, 5) the incidence of diseases in relative to the individual teeth. The results were obtained as follows. 1) Among the total of 300 cases of the patients, the frequency of dominant diseases of patients were fractures of facial bone (44.3 {+-} 2.87%), inflammatory diseases (22.7 {+-} 2.39%), cysts (11.1 {+-} 1.62%), tumors(10.7 {+-} 1.77%), maxillary sinusitis (7.9 {+-} 1.56%), temporomandibular joint disorders(3.3 {+-} 1.05%) in the order. 2) The sex ratio of male to female in occurrence of jaw fractures were 7.3 : 1, temporomandibular joint disorders were 2.1 : 1, inflammatory diseases were 1.8:1, maxillary sinusitis were 1.7 : 1, but tumors were 1: 1, while cysts were 1:1 .2 in sex difference.3) The predominant region of mandibular fractures were symphysis (17.3 {+-} 3.27%), canine region (15.0 {+-} 3.09%), and angle region(14.3 {+-} 3.04%) in the order. Inflammatory diseases were occurred frequently in mandible and it's left side were a little dominant. Odontogenic cysts were observed frequently in maxilla, but regardless of right and left. Carcinomas were involved most frequently in maxilla, while sarcomas and ameloblastomas in mandible. Frequency of the maxillary sinusitis w ere dominant in right side and molar area, also temporomandibular joint disorders were dominant in right side. 4) To study comparing with the age, jaw fractures showed the highest ratio at the 2nd decade (32.3 {+-} 4.06%), and 3rd decade (27.8 {+-} 3.89%), 4th decade (19.6 {+-} 3.44%), 6th decade (9.0 {+-} 2.47%), 5th decade(6.0 {+-} 2.06%), lst decade(5.3 {+-} 1

    Elevated levels of the astroglial protein S100B have been shown to predict sport-related concussion. However, S100B levels within an athlete can vary depending on the type of physical activity (PA) engaged in and the methodologic approach used to measure them. Thus, appropriate reference values in the diagnosis of concussed athletes remain undefined. The purpose of our systematic literature review was to provide an overview of the current literature examining S100B measurement in the context of PA. The overall goal is to improve the use of the biomarker S100B in the context of sport-related concussion management. PubMed, SciVerse Scopus, SPORTDiscus, CINAHL, and Cochrane. We selected articles that contained (1) research studies focusing exclusively on humans in which (2) either PA was used as an intervention or the test participants or athletes were involved in PA and (3) S100B was measured as a dependent variable. We identified 24 articles. Study variations included the mode of PA used as an intervention, sample types, sample-processing procedures, and analytic techniques. Given the nonuniformity of the analytical methods used and the data samples collected, as well as differences in the types of PA investigated, we were not able to determine a single consistent reference value of S100B in the context of PA. Thus, a clear distinction between a concussed athlete and a healthy athlete based solely on the existing S100B cutoff value of 0.1 μg/L remains unclear. However, because of its high sensitivity and excellent negative predictive value, S100B measurement seems to have the potential to be a diagnostic adjunct for concussion in sports settings. We recommend that the interpretation of S100B values be based on congruent study designs to ensure measurement reliability and validity.

    To describe epidemiologic features of sports-related genitourinary (GU) injuries and determine patient cohorts and particular sporting activities associated with increased GU injury risk. The National Electronic Injury Surveillance System, a data set validated to provide a probability sample of injury-related US emergency department (ED) presentations, was analyzed to characterize GU injuries between 2002 and 2010. A total of 13,851 observations were analyzed to derive national estimates. Between 2002 and 2010, an estimated 137,525 individuals (95% confidence interval, 104,490-170,620) presented to US EDs with GU injuries sustained during sporting activities. Nearly three-quarters of injuries occurred in the pediatric population. The most common product involved was a bicycle, representing approximately one-third of injuries in both adult and pediatric populations. Injuries related to team sports such as football, baseball or softball, basketball, and soccer were also common, particularly among boys where they represented a combined third of all injuries. Eighty-nine percent of all patients were evaluated and treated in the ED without inpatient admission. The large majority of injuries involved the external genitalia (60%), and significant injuries of paired GU organs (kidneys and testicles) requiring inpatient admission were rare (8.5%). Sports-related GU injuries are most commonly sustained during the use of a bicycle. However, there are other associated activities with identifiable high-risk cohorts, products, and situations. Consumers, practitioners, and injury-prevention experts can use our epidemiologic data to prioritize and develop strategies aimed at the prevention and limitation of such injuries, particularly when counseling at-risk cohorts, such as those with solitary kidneys or testicles.

    In Switzerland, ECG screening was first recommended for national squad athletes in 1998. Since 2001 it has become mandatory in selected high-risk professional sports. Its impact on the rates of sports-related sudden cardiac death (SCD) is unknown. We aimed to study the incidence, causes and time trends of sports-related SCD in comparison to SCD unrelated to exercise in Switzerland. We reviewed all forensic reports of SCDs of the German-speaking region of Switzerland in the age group of 10 to 39 years, occurring between 1999 and 2010. Cases were classified into three categories based on whether or not deaths were associated with sports: no sports (NONE), recreational sports (REC), and competitive sports (COMP). Over the 12-year study period, 349 SCD cases were recorded (mean age 30±7 years, 76.5% male); 297 cases were categorized as NONE, 31 as REC, and 21 as COMP. Incidences of SCD per 100,000 person-years [mean (95% CI)] were the lowest in REC [0.43 (0.35-0.56)], followed by COMP [1.19 (0.89-1.60)] and NONE [2.46 (2.27-2.66)]. In all three categories, coronary artery disease (CAD) with or without acute myocardial infarction (MI) was the most common cause of SCD. Three professional athletes were identified in COMP category which all had SCD due to acute MI. There were no time trends, neither in overall, nor in cause-specific incidences of SCD. The incidence of SCD in young individuals in Switzerland is low, both related and unrelated to sports. In regions, like Switzerland, where CAD is the leading cause of SCD associated with competitions, screening for cardiovascular risk factors in addition to the current PPS recommendations might be indicated to improve detection of silent CAD and further decrease the incidence of SCD.

    Sport-related concussion (SRC) is a clinical diagnosis made after a sport-related head trauma. Inconsistency exists regarding appropriate methods for assessing SRC, which focus largely on symptom-scores, neurocognitive functioning and postural stability. Systematic literature review. MEDLINE, EMBASE, PsycINFO, Cochrane-DSR, Cochrane CRCT, CINAHL, SPORTDiscus (accessed July 9, 2016). Original (prospective) studies reporting on postinjury assessment in a clinical setting and evaluation of diagnostic tools within 2 weeks after an SRC. Forty-six studies covering 3284 athletes were included out of 2170 articles. Only the prospective studies were considered for final analysis (n=33; 2416 athletes). Concussion diagnosis was typically made on the sideline by an (certified) athletic trainer (55.0%), mainly on the basis of results from a symptom-based questionnaire. Clinical domains affected included cognitive, vestibular and headache/migraine. Headache, fatigue, difficulty concentrating and dizziness were the symptoms most frequently reported. Neurocognitive testing was used in 30/33 studies (90.9%), whereas balance was assessed in 9/33 studies (27.3%). The overall quality of the studies was considered low. The absence of an objective, gold standard criterion makes the accurate diagnosis of SRC challenging. Current approaches tend to emphasise cognition, symptom assessment and postural stability with less of a focus on other domains of functioning. We propose that the clinical assessment of SRC should be symptom based and interdisciplinary. Whenever possible, the SRC assessment should incorporate neurological, vestibular, ocular motor, visual, neurocognitive, psychological and cervical aspects. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Recently, female sports participation has increased, and there is a tendency for women to experience more symptoms and variable presentation after sport-related concussion (SRC). The purpose of this study was to determine whether sex differences exist in time to begin a return-to-play (RTP) progression after an initial SRC. After initial SRC, female athletes (11-20 years old) would take longer to begin an RTP progression compared with age-matched male athletes. Retrospective cohort study. Level 3. A total of 579 participants (365 males [mean age, 15.0 ± 1.7 years], 214 females [mean age, 15.2 ± 1.5 years]), including middle school, high school, and collegiate athletes who participated in various sports and experienced an initial SRC were included and underwent retrospective chart review. The following information was collected: sex, age at injury, sport, history of prior concussion, date of injury, and date of initiation of RTP progression. Participants with a history of more than 1 concussion or injury sustained from non-sport-related activity were excluded. Despite American football having the greatest percentage (49.2%) of sport participation, female athletes took significantly longer to start an RTP progression after an initial SRC (29.1 ± 26.3 days) compared with age-matched male athletes (22.7 ± 18.3 days; P = 0.002). On average, female athletes took approximately 6 days longer to begin an RTP progression compared with age-matched male athletes. This suggests that sex differences exist between athletes, ages 11 to 20 years, with regard to initiation of an RTP progression after SRC. Female athletes may take longer to recover after an SRC, and therefore, may take longer to return to sport. Sex should be considered as part of the clinical decision-making process when determining plan of care for this population. © 2016 The Author(s).

    Studies indicate that those participating in sports are a high-risk population for hazardous alcohol use. Previous research identifies psychosocial drivers underpinning this link between sports participation and risky drinking behavior; however, the evidence is restricted to cross-sectional prevalence studies. Theoretical evaluations suggest that psychologically constructed identities are a defining factor for behaviors in this context. Therefore, the present study sought to examine longitudinally the relationships among sports-related identities, well-being, and alcohol behaviors in those participating in sports. Respondents completed self-report questionnaires on their alcohol consumption, drinking motives, athlete identity (personal identity), sports group identification (social identity), and general well-being. A sample of 475 participants (male = 55.6%; mean age = 20.2 years) provided data at Time 1 for cross-sectional analysis. Longitudinal associations were conducted with 92 participants (male = 42.4%; mean age = 20.8 years) who provided follow-up data (Time 1 and 6 months later). Cross-sectional results revealed an association between social identity and alcohol consumption, which was fully mediated by positive reinforcement drinking motives. Correlation analysis found a significant positive relationship between Time 1 alcohol consumption and social identity 6 months later. Furthermore, social identity was positively associated with consumption, whereas athlete identity was negatively associated therewith. Finally, well-being was positively associated only with sports group identification over time. Our findings suggest that sport-related drinking may be an avenue for building group identification, and this identification is linked to well-being.

    The development of new technologies such as three-dimensional (3D) planning has changed the everyday practice in maxillofacial surgery. Rapid prototyping associated with the 3D planning has also enabled the creation of patient specific surgical tools, such as cutting guides. As with all new technologies, uses, practicalities, cost effectiveness and especially benefits for the patients have to be carefully evaluated. In this paper, several examples of 3D planning that have been used in our institution are presented. The advantages such as the accuracy of the reconstructive surgery and decreased operating time, as well as the difficulties have also been addressed.

    To prospectively examine recovery of cognitive function within one month following subconcussive sports related head trauma. A prospective study of New York State licensed professional boxers who underwent testing of cognitive functioning before and after (within days, one week, and one month) a professional bout. Male professional athletes recruited from the New York State Athletic Commission and local boxing gyms. Twenty-six licensed professional boxers were enrolled in the protocol. Data is presented on the 18 participants who completed testing on at least three of the four time points. Serial neuropsychological assessment before and after the athletes engaged in competition. Neuropsychological measures of cognitive functioning, including new learning and memory, information processing speed, and mental flexibility. A series of repeated measures MANOVAS revealed significant within subject differences across testing on complex information processing and verbal fluency. Post hoc analyses indicated significant differences between time 1 (baseline) and time 4 (one month post), with scores one month following the bout indicating significantly improved performance. Memory scores did not change significantly across testing; however, prior boxing exposure measured by total number of professional bouts was associated with poorer memory performance. Cognitive testing one month following participation in a professional boxing bout yielded scores suggestive of recovery to a level above the baseline. We conclude that baseline assessment taken during periods of intense training are likely confounded by other pre-bout conditions (i.e., sparring, rapid weight loss, pre-bout anxiety) and do not represent true baseline abilities. Instability of performance associated with mild head injury may complicate the interpretation of post-injury assessments. Practice effects may also confound the interpretation of serial assessments, leading to underestimation of the effects of sports

    Aetiology of oral and maxillofacial injuries in this country includes motorvehicle accident (MVA), fall, industrial accidents and others. Among these causes, MVA accident is the predominant cause of injury in Malaysia. A retrospective record review was carried out using hospital records of all patients who sustained oral and maxillofacial injury at the Department of Oral Surgery, Seremban Hospital, Negeri Sembilan, Malaysia between 1998 and 2002. Information related to demographics, aetiology of trauma, vehicles involved in collision, location of injuries and treatment modalities were reviewed. Two thousand nine hundred and eighty-six patients sustained oral and maxillofacial injuries. Of these patients, 79.2% were men and the remaining were women. Among all the races, Malays had the highest involvement (50.6%) followed by Indians (24.5%), Chinese (19.6%) and others (5.3%). There were statistically significant results on the association of aetiology and the ethnic groups, in the age group of 30 years or less and male gender (P < 0.001). The most common injury was the soft-tissue injury followed by dental and dentoalveolar injuries and bony fracture. Among all facial fractures, 66.3% were managed conservatively, 13% were treated surgically and 19.7% did not have any intervention. In relation to dental and dentoalveolar injuries, 64.8% had treatment in the form of splinting, restorations or dental extraction. The rest of the patients (35.2%) were referred to their dentists or did not have any active treatment at Seremban Hospital. Most of the dental and facial injuries in Seremban Hospital were caused by MVA and were predominantly managed using conservative methods. © 2011 John Wiley & Sons A/S.

    The utilisation of vascularised and free bone autografts remain the goal standard in maxillofacial reconstructive surgery in Malaysia, but the use of freeze dried bone allograft is still widely practiced in many centres with variable results. This study evaluate the effectiveness and clinical efficacy of using radiation sterilised freeze dried bone allografts in oral and maxillofacial reconstructive surgery. The bone grafts were prepared at the Malaysian National Tissue Bank. Seventy eight patients who had undergone oral and Maxillofacial surgical procedures with reconstruction using bone allografts were included in this study. 50 patients were male and 28 patients were female and their age ranged from 14 to 75 years. Forty two patients underwent enucleation of benign cystic lesions in the jaws, 15 patients underwent repair of orbital floor fractures, 6 patients of jaw fractures with partial loss of bone while 8 patients underwent augmentation of depressed cheek bone. Another 4 patients had partial resection of the mandible because of cancer and 3 patients had facial osteotomies. A follow up period of 12 months up to 4 years was carried out. The patients were assessed both clinically and radiologically throughout their follow up visits. Clinical assessment showed no evidence of rejection of the implanted freeze dried allografts. Bone allografts implanted as inlay grafts demonstrated a better clinical performance than onlay grafts and the poorest results were obtained following bridging bony defects in the jaws. Radiation sterilised freeze dried bone allografts produced at the Malaysian National Tissue Bank are bio-compatible, functional, and provide predictable results when applied to selected areas of the facial skeleton

    2016-04-01

    Dracunculiasis, otherwise known as guinea worm disease (GWD), is caused by infection with the nematode Dracunculus medinensis. This nematode is transmitted to humans exclusively via contaminated drinking water. The transmitting vectors are Cyclops copepods (water fleas), which are tiny free-swimming crustaceans usually found abundantly in freshwater ponds. Humans can acquire GWD by drinking water that contains vectors infected with guinea worm larvae. This disease is prevalent in some of the most deprived areas of the world, and no vaccine or medicine is currently available. International efforts to eradicate dracunculiasis began in the early 1980s. Most dentists and maxillofacial surgeons have neglected this kind of parasite infection. However, when performing charitable work in developing countries near the tropic lines or other regions where GWD is endemic, it is important to consider GWD in cases of swelling or tumors of unknown origin. This paper reviews the pathogenesis, epidemiology, clinical criteria, diagnostic criteria, treatment, and prevention of dracunculiasis. It also summarizes important factors for maxillofacial surgeons to consider.

Outpatient concussion clinic. Twenty athletes aged 12 to 19 years with diagnosed SRC. Prospective study including visit 1 (sleep across recovery. Symptom, neurocognitive, and vestibular/oculomotor scores; sleep and activity data (Actigraph GT3x+) RESULTS:: The maximum intensity of physical activity increased (P = .009) and time in bed decreased throughout recovery (P = .026). Several physical activity metrics from 0 to 6 days postinjury were predictive of worse vestibular/oculomotor scores at visit 2 (P sleep 0 to 6 days postinjury were associated with worse reaction time at visit 2 (P sleep change from the acute to subacute postinjury time period in adolescent SRC patients. In our small sample, excess physical activity and poor sleep the first week postinjury may be associated with worse outcomes at follow-up in the subacute stage of recovery. This study further supported the feasibility of research utilizing wearable technology in concussion patients, and future research in a large, diverse sample of concussion patients examined at concise time intervals postinjury is needed.

Discussion: our results revealed that three clinical balance test batteries-TUG, TG and WOBB tests are the stability measures to assess the sports related concussion. Also, the results of current study showed that the time to perform these tests was slower than the other studies.

    Conceptual models for assessing and treating sport-related concussion (SRC) have evolved from a homogenous approach to include different clinical profiles that reflect the heterogeneous nature of this injury and its effects. There are six identified clinical profiles, or subtypes from SRC, and one such clinical profile is the anxiety/mood profile. Athletes with this profile experience predominant emotional disturbance and anxiety following SRC. The purpose of this targeted review was to present an overview of the empirical evidence to support factors contributing to the anxiety/mood profile, along with methods of evaluation and treatment of this clinical profile following SRC. We discuss the potential underlying mechanisms and risk factors for this clinical profile, describe comprehensive assessments to evaluate concussed athletes with an anxiety/mood clinical profile, and explore behavioral and other interventions for treating these athletes. Although there is limited, but growing empirical evidence for the anxiety/mood clinical profile following SRC, understanding this clinical profile is germane for clinicians who are treating athletes with emotional sequelae after SRC.

    To determine similarities and differences in the performance of female and male athletes on neuropsychological measures of frontal lobe functioning. A cross-sectional study of male and female college-aged athletes involved in one of the following sports: hockey, basketball, softball, lacrosse, soccer, swimming, and track. Division III college. A total of 262 athletes (male, n=157; female, n=105) participated in the study. Controlled Oral Word Association (letters F, A, S), Cognitive Assessment System (Planned Codes, Planned Connections, Number Detection), and WAIS-R-NI Vocabulary were administered to all athletes. MANCOVA was performed with gender and sport as fixed factors. Female athletes displayed faster and more accurate performance on perceptual-motor tasks (Pgender and sport. Gender- and sport-specific performances on perceptual-motor and verbal fluency tasks were found. Adding cognitive components to base functions eliminates gender- and sports-related distinctions, suggesting that existing differences are related to basic, fundamental skills, which are inherent and practiced within the respective sport. Understanding the differences and similarities across sports and gender on various neurocognitive measures is relevant for determining group differences in studies examining the consequences of mild traumatic brain injury among athletes.

    2006-09-29

    Participation in high school sports helps promote a physically active lifestyle. High school sports participation has grown from an estimated 4 million participants during the 1971-72 school year to an estimated 7.2 million in 2005-06. However, despite the documented health benefits of increased physical activity (e.g., weight management, improved self-esteem, and increased strength, endurance, and flexibility), those who participate in athletics are at risk for sports-related injuries. High school athletes account for an estimated 2 million injuries, 500,000 doctor visits, and 30,000 hospitalizations annually. To date, the study of these injuries has been limited by inabilities to calculate injury rates, compare results among groups, and generalize findings from small, nonrepresentative samples. During the 2005-06 school year, researchers at a children's hospital in Ohio used an Internet-based data-collection tool to pilot an injury surveillance system among athletes from a representative national sample of U.S. high schools. This report summarizes the findings of that study, which indicated that participation in high school sports resulted in an estimated 1.4 million injuries at a rate of 2.4 injuries per 1,000 athlete exposures (i.e., practices or competitions). Surveillance of exposure-based injury rates in a nationally representative sample of high school athletes and analysis of injury patterns can help guide activities aimed at reducing these injuries.

    2013-12-01

    Since the late nineties, computerized neurocognitive testing has become a central component of sport-related concussion (SRC) management at all levels of sport. In 2005, a review of the available evidence on the psychometric properties of four computerized neuropsychological test batteries concluded that the tests did not possess the necessary criteria to warrant clinical application. Since the publication of that review, several more computerized neurocognitive tests have entered the market place. The purpose of this review is to summarize the body of published studies on psychometric properties and clinical utility of computerized neurocognitive tests available for use in the assessment of SRC. A review of the literature from 2005 to 2013 was conducted to gather evidence of test-retest reliability and clinical validity of these instruments. Reviewed articles included both prospective and retrospective studies of primarily sport-based adult and pediatric samples. Summaries are provided regarding the available evidence of reliability and validity for the most commonly used computerized neurocognitive tests in sports settings.

    The objective of this systematic review was to evaluate the evidence regarding rest and active treatment/rehabilitation following sport-related concussion (SRC). Systematic review. MEDLINE (OVID), CINAHL (EbscoHost), PsycInfo (OVID), Cochrane Central Register of Controlled Trials (OVID), SPORTDiscus (EbscoHost), EMBASE (OVID) and Proquest DissertationsandTheses Global (Proquest) were searched systematically. Studies were included if they met the following criteria: (1) original research; (2) reported SRC as the diagnosis; and (3) evaluated the effect of rest or active treatment/rehabilitation. Review articles were excluded. Twenty-eight studies met the inclusion criteria (9 regarding the effects of rest and 19 evaluating active treatment). The methodological quality of the literature was limited; only five randomised controlled trials (RCTs) met the eligibility criteria. Those RCTs included rest, cervical and vestibular rehabilitation, subsymptom threshold aerobic exercise and multifaceted collaborative care. A brief period (24-48 hours) of cognitive and physical rest is appropriate for most patients. Following this, patients should be encouraged to gradually increase activity. The exact amount and duration of rest are not yet well defined and require further investigation. The data support interventions including cervical and vestibular rehabilitation and multifaceted collaborative care. Closely monitored subsymptom threshold, submaximal exercise may be of benefit.

    This study evaluated the test-retest reliability of a novel computer-based, portable balance assessment tool, the Equilibrate System (ES), used to diagnose sports-related concussion. Twenty-seven students participated in ES testing consisting of three sessions over 4 weeks. The modified Balance Error Scoring System was performed. For each participant, test-retest reliability was established using the intraclass correlation coefficient (ICC). The ES test-retest reliability from baseline to week 2 produced an ICC value of 0.495 (95% CI, 0.123-0.745). Week 2 testing produced ICC values of 0.602 (95% CI, 0.279-0.803) and 0.610 (95% CI, 0.299-0.804), respectively. All other single measures test-retest reliability values produced poor ICC values. Same-day ES testing showed fair to good test-retest reliability while interweek measures displayed poor to fair test-retest reliability. Testing conditions should be controlled when using computerized balance assessment methods. ES testing should only be used as a part of a comprehensive assessment.

    With increasing participation and intensity of training in youth sports in the United States, the incidence of sports-related injuries is increasing, and the types of injuries are shifting. In this article, the authors review sports injuries of the lower extremity, including both acute and overuse injuries, that are common in or specific to the pediatric population. Common traumatic injuries that occur in individuals of all ages (eg, tears of the acetabular labrum and anterior cruciate ligament) are not addressed, although these occur routinely in pediatric sports. However, some injuries that occur almost exclusively in high-level athletes (eg, athletic pubalgia) are reviewed to increase awareness and understanding of these entities among pediatric radiologists who may not be familiar with them and thus may not look for them. Injuries are described according to their location (ie, hip, knee, or foot and ankle) and pathologic process (eg, apophysitis, osteochondritis dissecans). Examples of abnormalities and normal variants of the anatomy that are often misdiagnosed are provided. The injuries reviewed represent a common and growing subset of pathologic processes about which all pediatric and musculoskeletal radiologists should be knowledgeable. Understanding physeal injury is especially important because missed diagnoses can lead to premature physeal closure and osteoarthritis. © RSNA, 2016.

    To offer an overview of sport-related concussion (SRC) prevention and education strategies in the context of the socioecological framework (SEF). Athletic trainers (ATs) will understand the many factors that interact to influence SRC prevention and the implications of these interactions for effective SRC education. Concussion is a complex injury that is challenging to identify and manage, particularly when athletes fail to disclose symptoms to their health care providers. Education is 1 strategy for increasing disclosure. However, limited information addresses how ATs can integrate the many factors that may influence the effectiveness of SRC education into their specific settings. Public health models provide an example through the SEF, which highlights the interplay among various levels of society and sport that can facilitate SRC prevention strategies, including education. For ATs to develop appropriate SRC prevention strategies, a framework for application is needed. A growing body of information concerning SRC prevention indicates that knowledge alone is insufficient to change concussion-related behaviors. The SEF allows this information to be considered at levels such as policy and societal, community, interpersonal (relationships), and intrapersonal (athlete). The use of such a framework will facilitate more comprehensive SRC prevention efforts that can be applied in all athletic training practice settings. Clinical Applications: Athletic trainers can use this information as they plan SRC prevention strategies in their specific settings. This approach will aid in addressing the layers of complexity that exist when developing a concussion-management policy and plan.

    Although science findings and treatment approaches of a concussion have changed in recent years, there continue to be challenges in understanding the nature of the post-concussion behavior. There is growing a body of evidence that some deficits can be related to an impaired auditory processing. To assess auditory comprehension changes over time following sport-related concussion (SRC) in young athletes. A prospective, repeated measures mixed-design was used. A sample of concussed athletes ( n  = 137) and the control group consisted of age-matched, non-concussed athletes ( n  = 143) were administered Subtest VIII of the Computerized-Revised Token Test (C-RTT). The 88 concussed athletes selected for final analysis (neither previous history of brain injury, neurological, psychiatric problems, nor auditory deficits) were evaluated after injury during three sessions (PC1, PC2, and PC3); controls were tested once. Between- and within-group comparisons using RMANOVA were performed on the C-RTT Efficiency Score (ES). ES of the SRC athletes group improved over consecutive testing sessions ( F  =   14.7, p   2.0, Ps integration and/or motor execution can be compromised after a concussion.

    Maxillofacial trauma in children is not common worldwide. Domestic injuries are frequently seen in younger children while older children are mostly involved in motor vehicle accidents (MVA). The objective of this study was to analyze the pattern of maxillofacial injuries in pediatric patients referred to three government main hospitals in different areas of West Malaysia. Patients' records of three selected hospitals in Malaysia (National University of Malaysia Hospital, Kajang Hospital and Seremban Hospital) from January 1999 to December 2001 were reviewed. Data associated with demographics, etiology of injury in relation to age group, type of injuries whether soft tissues of hard tissue in relation to age group and treatment modalities were collected. A total of 521 pediatric patients' records were reviewed. Malays made up the majority of patients with maxillofacial injuries in the three hospitals. Males outnumbered females in all the three hospitals. Injuries commonly occur in the 11-16 years old. MVA was the most common etiology followed by fall and assault. Soft tissue injuries were the most common type of injuries in all the hospitals. In relation to fractures, mandible was the most common bone to fracture with condyle being the most common site. Orbital fracture was the most common fracture in the midfacial area. Most of the fractures were managed conservatively especially in the younger age groups. Open reduction with or without internal fixation was more frequently carried out in the 11-16 years old group. Children exhibit different pattern of clinical features depending on the etiology and stage of their bone maturation. A dedicated team, who is competent in trauma and aware of the unique anatomy, physical and psychological characteristics of children, should manage pediatric patient with trauma.

    Maxillofacial trauma is rare in children younger than the age of 5 years (range 0.6%-1.2%), and they can require different clinical treatment strategies compared with fractures in the adult population because of concerns regarding mandibular growth and development of dentition. A 5-year-old girl with a history of falling from a bicycle 7 hours earlier was referred to the department of oral and maxillofacial surgery. Multislice computed tomographic examination demonstrated a bilateral fracture of the mandibular condyle neck associated with minimal fracture of the alveolar ridge of the maxilla. The multislice computed tomographic scan also demonstrated dislocation on the right condyle neck and, on the left side, a medial inclination of approximately 45 degrees associated with greenstick fracture of the right parasymphysis region. In this particular case, orthodontic rubber elastics in combination with fixed orthodontic brackets provided good results in the treatment of bilateral condyle neck fractures associated with greenstick fracture of parasymphysis.

    The management of sports-related concussions (SRCs) utilizes serial neurocognitive assessments and self-reported symptom inventories to assess recovery and safety for return to play (RTP). Because postconcussive RTP goals include symptom resolution and a return to neurocognitive baseline levels, clinical decisions rest in part on understanding modifiers of this baseline. Several studies have reported age and sex to influence baseline neurocognitive performance, but few have assessed the potential effect of sleep. We chose to investigate the effect of reported sleep duration on baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) performance and the number of patient-reported symptoms. We hypothesized that athletes receiving less sleep before baseline testing would perform worse on neurocognitive metrics and report more symptoms. Cross-sectional study; Level of evidence, 3. We retrospectively reviewed 3686 nonconcussed athletes (2371 male, 1315 female; 3305 high school, 381 college) with baseline symptom and ImPACT neurocognitive scores. Patients were stratified into 3 groups based on self-reported sleep duration the night before testing: (1) short, sleep duration on baseline ImPACT performance. A univariate ANCOVA was performed to investigate the influence of sleep on total self-reported symptoms. When controlling for age and sex as covariates, the MANCOVA revealed significant group differences on ImPACT reaction time, verbal memory, and visual memory scores but not visual-motor (processing) speed scores. An ANCOVA also revealed significant group differences in total reported symptoms. For baseline symptoms and ImPACT scores, subsequent pairwise comparisons revealed these associations to be most significant when comparing the short and intermediate sleep groups. Our results indicate that athletes sleeping fewer than 7 hours before baseline testing perform worse on 3 of 4 ImPACT scores and report more symptoms. Because SRC management and RTP

    A combination of magnetic resonance imaging (MRI) with real-time high-resolution ultrasound (US) known as fusion imaging may improve visualization of musculoskeletal (MSK) sports medicine injuries. The aim of this study was to evaluate the applicability of MRI-US fusion technology in MSK sports medicine. This study was conducted by the medical services of the FC Barcelona. The participants included volunteers and referred athletes with symptomatic and asymptomatic MSK injuries. All cases underwent MRI which was loaded into the US system for manual registration on the live US image and fusion imaging examination. After every test, an evaluation form was completed in terms of advantages, disadvantages, and anatomic fusion landmarks. From November 2014 to March 2015, we evaluated 20 subjects who underwent fusion imaging, 5 non-injured volunteers and 15 injured athletes, 11 symptomatic and 4 asymptomatic, age range 16-50 years, mean 22. We describe some of the anatomic landmarks used to guide fusion in different regions. This technology allowed us to examine muscle and tendon injuries simultaneously in US and MRI, and the correlation of both techniques, especially low-grade muscular injuries. This has also helped compensate for the limited field of view with US. It improves spatial orientation of cartilage, labrum and meniscal injuries. However, a high-quality MRI image is essential in achieving an adequate fusion image, and 3D sequences need to be added in MRI protocols to improve navigation. The combination of real-time MRI and US image fusion and navigation is relatively easy to perform and is helping to improve understanding of MSK injuries. However, it requires specific skills in MSK imaging and still needs further research in sports-related injuries. Toshiba Medical Systems Corporation.

    To compare the knowledge and use of recommendations for the management of sport-related concussion (SRC) among sport and exercise medicine physicians (SEMPs) and emergency department physicians (EDPs) to assess the success of SRC knowledge transfer across Canada. A self-administered, multiple-choice survey accessed via e-mail by SEMPs and EDPs. The survey had been assessed for content validity. Canada. The survey was completed between May and July 2012 by SEMPs who had passed the diploma examination of the Canadian Academy of Sport and Exercise Medicine and by EDPs who did not hold this diploma. Knowledge and identification of sources of concussion management information, use of concussion diagnosis strategies, and whether physicians use common and consistent terminology when explaining cognitive rest strategies to patients after an SRC. There was a response rate of 28% (305 of 1085). The SEMP and EDP response rates were 41% (147 of 360) and 22% (158 of 725), respectively. Of the responses, 41% of EDPs and 3% of SEMPs were unaware of any consensus statements on concussion in sport; 74% of SEMPs used the Sport Concussion Assessment Tool, version 2 (SCAT2), "usually or always," whereas 88% of EDPs never used the SCAT2. When queried about how cognitive rest could best be achieved after an SRC, no consistent answer was documented. Differences and a lack of consistency in the implementation of recommendations for SRC patients were identified for SEMPs and EDPs. It appears that the SCAT2 is used more in the SEMP setting than in the emergency context. Further knowledge transfer efforts and research should address the barriers to achieving more consistent advice given by physicians who attend SRC patients.

    To determine physician-reported adherence to and support of the 2010 Massachusetts youth concussion law, as well as barriers to care and clinical practice in the context of legislation. Primary care physicians (n = 272) in a large pediatric network were eligible for a cross-sectional survey in 2014. Survey questions addressed key policy and practice provisions: concussion knowledge, state regulations and training, practice patterns, referrals, patient characteristics, and barriers to care. Analyses explored relationships between practice and policy, adjusting for physician demographic and practice characteristics. The survey response rate was 64% among all responders (173 of 272). A total of 146 respondents who had evaluated, treated, or referred patients with a suspected sports-related concussion in the previous year were eligible for analysis. The vast majority (90%) of providers agreed that the current Massachusetts laws regarding sports concussions are necessary and support the major provisions. Three-quarters (74%) had taken a required clinician training course on concussions. Those who took training courses were significantly more likely to develop individualized treatment plans (OR, 3.6; 95% CI, 1.1-11.0). Physician training did not improve screening of youth with concussion for depression or substance use. Most physicians (77%) advised patients to refrain from computer, telephone, or television for various time periods. Physicians reported limited communication with schools. Primary care physicians report being comfortable with the diagnosis and management of concussions, and support statewide regulations; however, adherence to mandated training and specific legal requirements varied. Broader and more frequent training may be necessary to align current best evidence with clinical care and state-mandated practice. Copyright © 2016 Elsevier Inc. All rights reserved.

    Various definitions for concussion have been proposed, each having its strengths and weaknesses. We reviewed and compared current definitions and identified criteria necessary for an operational definition of sports-related concussion (SRC) in preparation of the 5th Concussion Consensus Conference (Berlin, Germany). We also assessed the role of biomechanical studies in informing an operational definition of SRC. This is a systematic literature review. Data sources include MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Clinical Trials and SPORT Discus (accessed 14 September 2016). Eligibility criteria were studies reporting (clinical) criteria for diagnosing SRC and studies containing SRC impact data. Out of 1601 articles screened, 36 studies were included (2.2%), 14 reported on criteria for SRC definitions and 22 on biomechanical aspects of concussions. Six different operational definitions focusing on clinical findings and their dynamics were identified. Biomechanical studies were obtained almost exclusively on American football players. Angular and linear head accelerations linked to clinically confirmed concussions demonstrated considerable individual variation. SRC is a traumatic brain injury that is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces with several common features that help define its nature. Limitations identified include that the current criteria for diagnosing SRC are clinically oriented and that there is no gold/standard to assess their diagnostic properties. A future, more valid definition of SRC would better identify concussed players by demonstrating high predictive positive/negative values. Currently, the use of helmet-based systems to study the biomechanics of SRC is limited to few collision sports. New approaches need to be developed to provide objective markers for SRC. © Article author(s) (or their employer(s) unless otherwise

Risk of bias and level of evidence were evaluated by two authors. Following review of 3819 studies, 47 met inclusion criteria. Some former athletes have depression and cognitive deficits later in life, and there is an association between these deficits and multiple prior concussions. Former athletes are not at increased risk for death by suicide (two studies). Former high school American football players do not appear to be at increased risk for later life neurodegenerative diseases (two studies). Some retired professional American football players may be at increased risk for diminishment in cognitive functioning or mild cognitive impairment (several studies), and neurodegenerative diseases (one study). Neuroimaging studies show modest evidence of macrostructural, microstructural, functional and neurochemical changes in some athletes. Multiple concussions appear to be a risk factor for cognitive impairment and mental health problems in some individuals. More research is needed to better understand the prevalence of chronic traumatic encephalopathy and other neurological conditions and diseases, and the extent to which they are related to concussions and/or repetitive neurotrauma sustained in sports. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    College sport organizations and associations endorse concussion-management protocols and policies. To date, little information is available on concussion policies and practices at community college institutions. To assess and describe current practices and policies regarding the assessment, management, and return-to-play criteria for sport-related concussion (SRC) among member institutions of the California Community College Athletic Association (CCCAA). Cross-sectional study. Web-based survey. A total of 55 head athletic trainers (ATs) at CCCAA institutions. Data about policies, procedures, and practices regarding SRC were collected over a 3-week period in March 2012 and analyzed using descriptive statistics, the Fisher exact test, and the Spearman test. Almost half (47%) of ATs stated they had a policy for SRC assessment, management, and return to play at their institution. They reported being in compliance with baseline testing guidelines (25%), management guidelines (34.5%), and return-to-play guidelines (30%). Nearly 31% of ATs described having an SRC policy in place for academic accommodations. Conference attendance was positively correlated with institutional use of academic accommodations after SRC (r = 0.44, P = .01). The number of meetings ATs attended and their use of baseline testing were also positively correlated (r = 0.38, P = .01). At the time of this study, nearly half of CCCAA institutions had concussion policies and 31% had academic-accommodation policies. However, only 18% of ATs at CCCAA institutions were in compliance with all of their concussion policies. Our findings demonstrate improvements in the management of SRCs by ATs at California community colleges compared with previous research but a need for better compliance with SRC policies.

    Full Text Available It is the god given right of every human being to appear human. Few areas of dentistry offer more challenges to the technical skills or greater satisfaction for the successful rehabilitation of function and esthetics in the patient with gross anatomic defects and deformities of the maxillofacial region. Although remarkable advances in the surgical management of oral and facial defects, but cannot be satisfactorily repaired by plastic surgery alone. Hence, the demand for maxillofacial prosthetic devices for the rehabilitation of patients with congenital or acquired defects has intensified in recent years. This paper gives an insight into the latest innovations and improvisations in the field of maxillofacial prosthodontics.

    Full Text Available Gunshot injuries are rather serious but uncommon type of trauma in India. A 45-year-old male was presented with gunshot (pellets embedded in the maxillofacial area for 22 years. There is no consensus in the literature whether to attempt their removal or leave them in situ. Our patient had no long-term sequela like infection, fistula formation, carcinogenesis or metal poisoning to date except for chill feeling on cold days. Management of this patient presented a dilemma in treatment in view of the effects of foreign bodies in the maxillofacial area. Key words: Maxillofacial injuries; Wounds, gunshot; Firearms

    Fractures in sport are a specialised cohort of fracture injuries, occurring in a high functioning population, in which the goals are rapid restoration of function and return to play with the minimal symptom profile possible. While the general principles of fracture management, namely accurate fracture reduction, appropriate immobilisation and timely rehabilitation, guide the treatment of these injuries, management of fractures in athletic populations can differ significantly from those in the general population, due to the need to facilitate a rapid return to high demand activities. However, despite fractures comprising up to 10% of all of sporting injuries, dedicated research into the management and outcome of sport-related fractures is limited. In order to assess the optimal methods of treating such injuries, and so allow optimisation of their outcome, the evidence for the management of each specific sport-related fracture type requires assessment and analysis. We present and review the current evidence directing management of fractures in athletes with an aim to promote valid innovative methods and optimise the outcome of such injuries. From this, key recommendations are provided for the management of the common fracture types seen in the athlete. Six case reports are also presented to illustrate the management planning and application of sport-focussed fracture management in the clinical setting. PMID:26716081

    Over the past 20 years, clinical neuropsychologists have been at the forefront of both scientific and clinical initiatives aimed at developing evidence-based approaches to the evaluation and management of sport-related concussion. These efforts have directly impacted current policy on strategies for injury assessment and return-to-play by athletes after concussion. Many states are considering legislation requiring (a) education of athletes, parents, coaches, and school/organization officials on the recognition, evaluation, and management of sport-related concussions; (b) removal from play of any youth athlete that is suspected of having sustained a concussion; and (c) not allowing the student to return to participation until the student is evaluated and cleared for return to participation in writing by an appropriate healthcare professional. It is the official position of the American Academy of Clinical Neuropsychology (AACN), American Board of Neuropsychology (ABN), Division 40 (Neuropsychology) of the American Psychological Association (APA), and the National Academy of Neuropsychology (NAN) that neuropsychologists should be included among the licensed health care professionals authorized to evaluate, clinically manage, and provide return to play clearance for athletes who sustain a sport-related concussion.

    Full Text Available The discovery of stem cells is one of the greatest achievements of molecular and cell biology, and associated research has confirmed the possibility of self-renewal and differentiation into specialized tissue stem cells. The use of cellular technologies is an important trend in modern medicine. The aim of this article is to briefly review current findings on the use of stem cells in cardiology, endocrinology, neurology, traumatology, and maxillofacial surgery. All data were retrieved from experimental and clinical studies using various cell technologies. The material is part of ongoing maxillofacial surgery research to investigate the possible use of stem cells in reconstructive maxillofacial surgery for jaw bone pathologies in children. Present tissue engineering methods provide some opportunities for solving difficult clinical problems in oral and maxillofacial surgery. Despite some international achievements of effective application of IC in various diseases, clinical use in reconstructive surgery requires further investigation.

    Full Text Available This study aimed to analyze the effects of power training using traditional vertical resistance exercises versus direction specific horizontal inertial flywheel training on performance in common sport-related tasks. Twenty-three healthy and physically active males (age: 22.29 ± 2.45 years volunteered to participate in this study. Participants were allocated into either the traditional training (TT group where the half squat exercise on a smith machine was applied or the horizontal flywheel training (HFT group performing the front step exercise with an inertial flywheel. Training volume and intensity were matched between groups by repetitions (5-8 sets with 8 repetitions and relative intensity (the load that maximized power (Pmax over the period of six weeks. Speed (10 m and 20 m, countermovement jump height (CMJH, 20 m change of direction ability (COD and strength during a maximal voluntary isometric contraction (MVIC were assessed before and after the training program. The differences between groups and by time were assessed using a two-way analysis of variance with repeated measures, followed by paired t-tests. A significant group by time interaction (p=0.004 was found in the TT group demonstrating a significantly higher CMJH. Within-group analysis revealed statistically significant improvements in a 10 m sprint (TT: −0.17 0.27 s vs. HFT: −0.11 0.10 s, CMJH (TT: 4.92 2.58 cm vs. HFT: 1.55 2.44 cm and MVIC (TT: 62.87 79.71 N vs. HFT: 106.56 121.63 N in both groups (p < 0.05. However, significant differences only occurred in the 20 m sprint time in the TT group (−0.04 0.12 s; p = 0.04. In conclusion, the results suggest that TT at the maximal peak power load is more effective than HFT for counter movement jump height while both TT and HFT elicited significant improvements in 10 m sprint performance while only TT significantly improved 20 m sprint performance.

    Researchers have reported that sleep duration is positively related to baseline neurocognitive performance. However, researchers have yet to examine the effect of preinjury sleep difficulties on postconcussion impairments. To compare neurocognitive impairment and symptoms of athletes with preinjury sleep difficulties to those without after a sport-related concussion (SRC). Cohort study; Level of evidence, 3. The sample included 348 adolescent and adult athletes (age, mean ± SD, 17.43 ± 2.34 years) with a diagnosed SRC. The sample was divided into 2 groups: (1) 34 (10%) participants with preinjury sleep difficulties (sleeping less as well as having trouble falling asleep; SLEEP SX) and (2) 231 (66%) participants without preinjury sleep difficulties (CONTROL). The remaining 84 (24%) participants with minimal sleep difficulties (1 symptom) were excluded. Participants completed the Immediate Postconcussion Assessment and Cognitive Test (ImPACT) and Postconcussion Symptom Scale (PCSS) at baseline and 3 postinjury intervals (2, 5-7, and 10-14 days after injury). A series of repeated-measures analyses of covariance with Bonferroni correction, controlling for baseline non-sleep-related symptoms, were conducted to compare postinjury neurocognitive performance between groups. Follow-up exploratory t tests examined between-group differences at each time interval. A series of analyses of variance were used to examine total PCSS score, sleep-related, and non-sleep-related symptoms across time intervals between groups. Groups differed significantly in PCSS scores across postinjury intervals for reaction time (P SLEEP SX group performing worse than controls at 5-7 days (mean ± SD, 0.70 ± 0.32 [SLEEP SX], 0.60 ± 0.14 [CONTROL]) and 10-14 days (0.61 ± 0.17 [SLEEP SX]; 0.57 ± 0.10 [CONTROL]) after injury. Groups also differed significantly on verbal memory performance (P = .04), with the SLEEP SX (68.21 ± 18.64) group performing worse than the CONTROL group (76.76 ± 14

    Sleep disturbances are a hallmark sign after a sport-related concussion (SRC). Poor sleep has been shown to adversely affect baseline neurocognitive test scores, but it is not comprehensively understood how neurocognitive function is affected by disrupted sleep during recovery from a concussion. To identify the correlation between adolescent athletes' neurocognitive function and their self-reported sleep quantity and sleep disturbance symptoms during recovery from SRC. Cross-sectional study; Level of evidence, 3. Immediate Post-Concussion Assessment and Cognition Testing (ImPACT) data were retrospectively collected for 545 adolescent athletes treated for SRC at a sports medicine concussion clinic. Patients were stratified into groups based on 2 criteria: self-reported sleep duration and self-reported sleep disturbance symptoms during postinjury ImPACT testing. Sleep duration was classified as short (9 hours). Sleep disturbance symptoms were self-reported as part of the Post-Concussion Symptom Scale (PCSS) as either sleeping less than normal, sleeping more than normal, or having trouble falling asleep. One-way analyses of variance were conducted to examine the effects that sleep duration as well as self-reported sleep disturbance symptoms had on composite scores. A total of 1067 ImPACT tests were analyzed: test 1, 545; test 2, 380; and test 3, 142. Sleeping fewer than 7 hours the night before testing correlated with higher PCSS scores (P sleeping longer than 9 hours correlated with worse visual memory (P = .01), visual motor speed (P sleep disturbance symptoms, patients demonstrated worse composite scores during ImPACT testing when they self-reported sleeping more than normal (ImPACT test 1: verbal memory, P sleep had been disrupted. Adolescent patients who perceive that their sleep is somehow disrupted after SRC may report a greater number of concussion symptoms during their recovery. In addition, the study results suggest that sleeping more than normal may

      Without a true criterion standard assessment, the sport-related concussion (SRC) diagnosis remains subjective. Inertial balance sensors have been proposed to improve acute SRC assessment, but few researchers have studied their clinical utility.   To determine if group differences exist when using objective measures of balance in a sample of collegiate athletes with recent SRCs and participants serving as the control group and to calculate sensitivity and specificity to determine the diagnostic utility of the inertial balance sensor for acute SRC injuries.   Cohort study.   Multicenter clinical trial.   We enrolled 48 participants with SRC (age = 20.62 ± 1.52 years, height = 179.76 ± 10.00 cm, mass = 83.92 ± 23.22 kg) and 45 control participants (age = 20.85 ± 1.42 years, height = 177.02 ± 9.59 cm, mass = 74.61 ± 14.92 kg) at 7 clinical sites in the United States. All were varsity or club collegiate athletes, and all participants with SRC were tested within 72 hours of SRC.   Balance performance was assessed using an inertial balance sensor. Two measures (root mean square [RMS] sway and 95% ellipse sway area) were analyzed to represent a range of general balance measures. Balance assessments were conducted in double-legged, single-legged, and tandem stances.   A main effect for group was associated with the root mean square sway measure ( F 1,91 = 11.75, P = .001), with the SRC group demonstrating balance deficits compared with the control group. We observed group differences in the 95% ellipse sway area measure for the double-legged ( F 1,91 = 11.59, P = .001), single-legged ( F 1,91 = 6.91, P = .01), and tandem ( F 1,91 = 7.54, P = .007) stances. Sensitivity was greatest using a cutoff value of 0.5 standard deviations (54% [specificity = 71%]), whereas specificity was greatest using a cutoff value of 2 standard deviations (98% [sensitivity = 33%]).   Inertial balance sensors may be useful tools for objectively measuring balance during acute

    Universities are increasingly implementing programs to effectively respond to and manage sport-related concussions (SRCs). One such effort is to develop common data elements (CDEs) and standardize data collection methods. The objectives of this study were to describe CDEs currently collected by Big Ten and Ivy League universities for SRC studies, and to compare the data collected with the core CDEs recommended by the National Institute of Neurological Disorders and Stroke (NINDS). We conducted an anonymous cross-sectional online survey among medical staff at the 14 Big Ten and 8 Ivy League universities (one per university) between September and October 2015. The survey instrument, including 9 questions corresponding to the concussion data collected before, during, and after a concussion, was developed and pilot-tested before field use. We analyzed patterns of the concussion CDEs being collected, including when, what, and how the data were collected and stored, and compared them with the NINDS' recommended core CDEs. A total of 19 out of 22 universities were included, with 13 from Big Ten and 6 from Ivy-League universities. All 19 participating universities currently collected concussion data with athletes before, during, and after a concussion. Great similarities in data collection were observed at baseline and acutely post-concussion across participating universities. All 19 universities collected at least one of the ten recommended acute symptoms checklists, and 18 universities collected one of the four recommended core neuropsychological function cognitive measures. However, CDEs in the sub-acute and chronic timeframes were limited, with only 9 (47%) universities collecting post-concussion short to long term outcome data. While over 60% of universities collected and stored concussion data electronically, only 17% to 42% of data collected were readily available for research. Significant inter-institutional similarities in acute concussion CDEs were found. Further

    Sports-related injuries can have a substantial impact on the long-term health of student-athletes. The National Collegiate Athletic Association (NCAA) monitors injuries among college student-athletes at member schools. In academic year 2013-14, a total of 1,113 member schools fielded 19,334 teams with 478,869 participating student-athletes in NCAA championship sports (i.e., sports with NCAA championship competition) (1). External researchers and CDC used information reported to the NCAA Injury Surveillance Program (NCAA-ISP) by a sample of championship sports programs to summarize the estimated national cumulative and annual average numbers of injuries during the 5 academic years from 2009-10 through 2013-14. Analyses were restricted to injuries reported among student-athletes in 25 NCAA championship sports. During this period, 1,053,370 injuries were estimated to have occurred during an estimated 176.7 million athlete-exposures to potential injury (i.e., one athlete's participation in one competition or one practice). Injury incidence varied widely by sport. Among all sports, men's football accounted for the largest average annual estimated number of injuries (47,199) and the highest competition injury rate (39.9 per 1,000 athlete-exposures). Men's wrestling experienced the highest overall injury rate (13.1 per 1,000) and practice injury rate (10.2 per 1,000). Among women's sports, gymnastics had the highest overall injury rate (10.4 per 1,000) and practice injury rate (10.0 per 1,000), although soccer had the highest competition injury rate (17.2 per 1,000). More injuries were estimated to have occurred from practice than from competition for all sports, with the exception of men's ice hockey and baseball. However, injuries incurred during competition were somewhat more severe (e.g., requiring ≥7 days to return to full participation) than those acquired during practice. Multiple strategies are employed by NCAA and others to reduce the number of injuries in

    Oral and maxillofacial radiologists may teach, practice, and/or conduct research with regard to any aspect of radiology. They are also responsible for establishing guidelines for radiographic selection criteria, radiation safety, and quality assurance. Some oral and maxillofacial radiologists have joint appointments in medical radiology. This provides a collaborative working environment with medical radiologists, who generally are not conversant with the diagnostic imaging of the jaws

    Paralympic sport provides sporting opportunities for athletes with a disability, with the Paralympic Games as the main event. Participation in sport is, however, associated with a significant risk for sustaining injuries and illnesses. Our knowledge of sports-related injuries and illnesses in Paralympic sport is very limited and there are no large-scale epidemiological cohort studies. The purpose here is to present a protocol for a prospective longitudinal study: The Sports-Related Injuries and Illnesses in Paralympic Sport Study (SRIIPSS). An argument-based method for investigation of design problems was used to structure the study protocol. The primary requirement of the protocol is to allow prospective studies over time and include exposure to both training and competition. To reflect the complexity of Paralympic sport with athletes' pre-existing impairments, use of assistive equipment, pain and other and medical issues, it is required that the data collection system is specifically adapted to Paralympic sport. To allow the collection of data, at the same time as there is limited access to coaches and medical personnel, it is advantageous that data can be collected online directly from the athletes. Based on this a self-report athlete monitoring system will be developed, where the athletes can enter data weekly via their mobile phones or lap-tops. Data will be collected from around 100 Swedish Paralympic athletes for approximately 1 year, which will allow us to i) prospectively estimate the annual incidence of sports-related injuries and illnesses and ii) explore risk factors and mechanisms for sustaining sports-related injuries and illnesses based on athlete exposure and training loads. For effective implementation of injury and illness prevention measures, comprehensive epidemiological knowledge is required. This study will be the first prospective longitudinal self-report study of sports-related injuries and illnesses in Paralympic sport over a longer period

    Full Text Available The aim of the current study was to review the use of fresh frozen bone (FFB in oral and maxillofacial surgery. We performed a review of the articles published in the literature between 1976 and May 2014 analyzing three medical databases (PubMed, Cochrane Library, and Embase and using specific search terms. Literature analysis on FFB applications in oral and maxillofacial surgery revealed 47 articles between 1976 and May 2014. There are 46 clinical articles and one review. Clinical articles are represented by 22 case reports and case series and 24 retrospective studies. Classifying the scientific production by year of publication, it is evident that especially during the last 6 years there was an increase of FFB graft use in oral and maxillofacial approaches. The literature analysis on FFB's use shows that its application in oral and maxillofacial surgery began slowly in 1992 with Perrott and since 2006 it had a real development. The recent significant increase emphasizes the importance of FFB for bone regeneration in oral and maxillofacial surgery. This review found consistent evidence of FFB's use increase in oral and maxillofacial surgery suggesting a valid instrument for bone regeneration. To date, risks connected to the infections' transmission and to the immunogenic potential are extremely low and could be considered practically absent. So, this is an important alternative in the preimplant reconstructive surgery.

    The OOKP (osteo-odonto-keratoprosthesis) is the treatment of choice for conditions like Stevens-Johnson syndrome, ocular cicatricial pemphigoid, trachoma, multiple failed grafts and chemical burns which are not amenable to penetrating keratoplasty. The OOKP is an autograft which replaces the cornea with a polymethacrylate cylinder mounted on a tooth-bone complex. The aim of this paper was to retrospectively analyze the records in 26 patients undergoing OOKP surgery between 2007 and 2011. The paper describes our experience with the procedure, with emphasis on its oral and maxillofacial aspects and management of associated complications. The aetiology of blindness in 23 patients was Stevens-Johnson's syndrome and chemical burns in three. Twenty-two patients had their maxillary canines, two had mandibular canines and two had maxillary first premolars as the choice of donor tooth. An oroantral fistula developed in four patients. One patient needed to undergo a surgical procedure for closure of the same. Roots of adjacent teeth were exposed in 12 patients. Twenty-four patients underwent both stages of the procedure with 19 being visually rehabilitated successfully. There was no improvement in the vision of four patients. One patient was lost to follow-up. Two patients have yet to undergo Stage 2. Copyright © 2012 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

    To implement the database system of oral and maxillofacial radiological images using a commercial medical image management software with personally developed classification code. The image database was built using a slightly modified commercial medical image management software, Dr. Image v.2.1 (Bit Computer Co., Korea). The function of wild card '*' was added to the search function of this program. Diagnosis classification codes were written as the number at the first three digits, and radiographic technique classification codes as the alphabet right after the diagnosis code. 449 radiological films of 218 cases from January, 2000 to December, 2000, which had been specially stored for the demonstration and education at Dept. of OMF Radiology of Dankook University Dental Hospital, were scanned with each patient information. Cases could be efficiently accessed and analyzed by using the classification code. Search and statistics results were easily obtained according to sex, age, disease diagnosis and radiographic technique. Efficient image management was possible with this image database system. Application of this system to other departments or personal image management can be made possible by utilizing the appropriate classification code system.

    Background: Methods from the area of virtual reality are used in oral and maxillofacial surgery for the planning and three-dimensional individual simulation of surgeries. Simulation: In order to simulate complex surgeries with the aid of a computer, the diagnostic image data and especially various imaging modalities (CT, MRT, US) must be arranged in relation to each other, thus enabling rapid switching between the various modalities as well as the viewing of mixed images. Segmenting techniques for the reconstruction of three-dimensional representations of soft-tissue and osseous areas are required. We must develop ergonomic and intuitively useable interaction methods for the surgeon, thus allowing for precise and fast entry of the planned surgical intervention in the planning and simulation phase. Surgery: During the surgical phase, instrument navigation tools offer the surgeon interactive support through operation guidance and control of potential dangers. This feature is already available today. Future intraoperative assistance will take the form of such passive tools for the support of intraoperative orientation as well as so-called tracking systems (semi-active systems) which accompany and support the surgeons' work. The final form are robots which execute specific steps completely autonomously. Discussion: The techniques of virtual reality keep gaining in importance for medical applications. Many applications are still being developed or are still in the form of a prototype. However, it is already clear that developments in this area will have a considerable effect on the surgeon's routine work. (orig.) [de

    Pediatric patients present a unique challenge to maxillofacial surgeons in terms of their treatment planning as well as in their functional and nutritional needs which are different from that of adult patients. Early literature has advocated conservative closed management of pediatric fractures to prevent complications. However recent advances in maxillofacial surgery has enabled us to use biodegradable plates and screws, which overcomes the limitations of metallic plates. We present a comparison of two cases of parasymphysis fracture treated with circum-mandibular wiring and biodegradable plate fixation their outcome in terms of fracture healing and functional stability.

    Mandibular condylar fracture is one of the commonest maxillofacial fractures treated by maxillofacial surgeons. Demography of the patients, causation, and characteristics of the fracture depends on various socio-economic factors. Hence, maxillofacial surgeons should be familiar with epidemiology of mandibular condylar fracture. This study retrospectively describes the demography, etiology, fracture characteristics, and hospital utilization of surgically treated mandibular condylar fractures in a tertiary referral hospital in urban China in past five years. Data of all patients who underwent surgical management between 2011 and 2015 were collected. This included aetiology, characteristics of fracture, time, age, sex, associated injuries, and hospital utilization of 166 patients with 208 mandibular condylar fractures. These patients had undergone open reduction and internal fixation with either miniplates or lag screws. Among the fracture of head of mandibular condyle, 21.28% of the patients had the fracture segments removed. These data were statistically analyzed to describe the epidemiology of mandibular condylar fracture. Most of the patients had unilateral mandibular condylar fractures (74.7%). Male patients (76.51%) outnumbered female patients (23.49%) in this cohort. The average age of the patients was 37 years. The fractures were mostly caused by fall from height (60.84%) and were located at the condylar neck (53.61%). Most of the patients had other associated maxillofacial injuries (71.08%) which were mostly located at symphysis and parasymphysis (44.59%). It took 12.58 +/- 0.35 days of hospitalization for the treatment. Fall from height was the most prevalent cause of mandibular condylar injury in mountainous urban China. The people at highest risk were middle-aged men. Mandibular condylar fracture was mostly located at the condylar neck and was usually associated with fracture at the symphysis and parasymphysis.

    Pediatric patients present a unique challenge to maxillofacial surgeons in terms of their treatment planning as well as in their functional and nutritional needs which are different from that of adult patients. Early literature has advocated conservative closed management of pediatric fractures to prevent complications. However recent advances in maxillofacial surgery has enabled us to use biodegradable plates and screws, which overcomes the limitations of metallic plates. We present a compar...

    Sport-related traumatic brain injuries are a significant public health burden, with hundreds of thousands sustained annually in North America. While sports offer numerous physical and social health benefits, traumatic brain injuries such as concussion can seriously impact a player's life, athletic career, and sport enjoyment. The culture in many sports encourages winning at all costs, placing athletes at risk for traumatic brain injuries. As social media has become a central part of everyday life, the content of users' messages often reflects the prevailing culture related to a particular event or health issue. We hypothesized that Twitter data might be useful for understanding public perceptions and misperceptions of sport-related traumatic brain injuries. We performed a content and sentiment analysis of 7483 Twitter ® tweets related to traumatic brain injuries in sports collected during June and July 2013. We identified five major themes. Users tweeted about personal traumatic brain injuries experiences, reported traumatic brain injuries in professional athletes, shared research about sport-related concussions, and discussed policy and safety in injury prevention, such as helmet use. We identified mixed perceptions of and sentiment toward traumatic brain injuries in sports: both an understanding that brain injuries are serious and disregard for activities that might reduce the public burden of traumatic brain injuries were prevalent in our Twitter analysis. While the scientific and medical community considers a concussion a form of traumatic brain injuries, our study demonstrates a misunderstanding of this fact among the public. In our current digital age, social media can provide useful insight into the culture around a health issue, facilitating implementation of prevention and treatment strategies.

    Full Text Available There is a gap in knowledge about the mechanisms of sports-related brain injuries. The objective of this study was to determine the mechanisms of brain injuries among children and youth participating in team sports.We conducted a retrospective case series of brain injuries suffered by children participating in team sports. The Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP database was searched for brain injury cases among 5-19 year-olds playing ice hockey, soccer, American football (football, basketball, baseball, or rugby between 1990 and 2009. Mechanisms of injury were classified as "struck by player," "struck by object," "struck by sport implement," "struck surface," and "other." A descriptive analysis was performed.There were 12,799 brain injuries related to six team sports (16.2% of all brain injuries registered in CHIRPP. Males represented 81% of injuries and the mean age was 13.2 years. Ice hockey accounted for the greatest number of brain injuries (44.3%, followed by soccer (19.0% and football (12.9%. In ice hockey, rugby, and basketball, striking another player was the most common injury mechanism. Football, basketball, and soccer also demonstrated high proportions of injuries due to contact with an object (e.g., post among younger players. In baseball, a common mechanism in the 5-9 year-old group was being hit with a bat as a result of standing too close to the batter (26.1% males, 28.3% females.Many sports-related brain injury mechanisms are preventable. The results suggest that further efforts aimed at universal rule changes, safer playing environments, and the education of coaches, players, and parents should be targeted in maximizing prevention of sport-related brain injury using a multifaceted approach.

    The use of electronic tools in teaching is growing rapidly in all fields, and there are many options to choose from. We present one such platform, Learning Catalytics (LC) (Pearson, New York, NY, USA), which we utilized in our oral and maxillofacial radiology course for second-year dental students. The aim of our study was to assess the correlation between students' performance on course exams and self-assessment LC quizzes. The performance of 354 predoctoral dental students from 2 consecutive classes on the course exams and LC quizzes was assessed to identify correlations using the Spearman rank correlation test. The first class was given in-class LC quizzes that were graded for accuracy. The second class was given out-of-class quizzes that were treated as online self-assessment exercises. The grading in the self-assessment exercises was for participation only and not accuracy. All quizzes were scheduled 1-2 weeks before the course examinations. A positive but weak correlation was found between the overall quiz scores and exam scores when the two classes were combined (P<0.0001). A positive but weak correlation was likewise found between students' performance on exams and on in-class LC quizzes (class of 2016) (P<0.0001) as well as on exams and online LC quizzes (class of 2017) (P<0.0001). It is not just the introduction of technological tools that impacts learning, but also their use in enabling an interactive learning environment. The LC platform provides an excellent technological tool for enhancing learning by improving bidirectional communication in a learning environment.

    To find out the occurrence of postoperative nausea and vomiting (PONY) in oral and maxillofacial surgery done under general anaesthesia and to evaluate the purpose of using prophylactic antiemetic drugs. Design: Observational study. Place and Duration of the Study: Oral and Maxillofacial Department, KEMU / Mayo Hospital Lahore, from September 20 II to June 2012. Method: The number of patients who were operated in oral and maxillofacial surgery ward irrespective of age and gender for this study were 240. Risk factors related with PONY including gender, anesthetic drug used, surgical procedure, approach' used, total time of surgery and postoperative use of opioids were investigated. A wait and watch scheme was followed in patients with complaint of PONY. Antiemetics to be given in those cases where more than 2 episodes of vomiting took place. Results: It was found out that only II patients experienced from nausea and vomiting in post operative period. A notable relation was seen between PONY and female population, total time of surgery, anesthetic drug, surgery of tumor and temporomandibular joint. The surgical approach and opioids in postoperative period for PONY were found to be insignificant. Conclusion: PONY is not a significant finding in oral and maxillofacial surgery. We find out that there is no logic for the use of prophylactic antiemetic drugs in maxillofacial surgery. (author)

    Intraoperative computer-assisted navigation has gained acceptance in maxillofacial surgery with applications in an increasing number of indications. We adapted a commercially available wireless passive marker system which allows calibration and tracking of virtually every instrument in maxillofacial surgery. Virtual computer-generated anatomical structures are displayed intraoperatively in a semi-immersive head-up display. Continuous observation of the operating field facilitated by computer assistance enables surgical navigation in accordance with the physician's preoperative plans. This case report documents the potential for augmented visualization concepts in surgical resection of tumors in the oral and maxillofacial region. We report a case of T3N2bM0 carcinoma of the maxillary gingival which was surgically resected with the assistance of the Stryker Navigation Cart System. This system was found to be useful in assisting preoperative planning and intraoperative monitoring.

    Full Text Available The purpose of this study was to evaluate the effects of ovariectomy on intramuscular energy metabolism in adult rats. Based on the results, we discussed the skeletal muscle metabolism in female athlete with sports related amenorrhea. Twenty-five adult (20-week-old Sprague-Dawley female rats were used. Fifteen rats underwent ovariectomy (OVX group, and the other ten rats were sham-operated (Sham group. One and four weeks after surgery, muscular oxidative capacity was measured using 31P-MR spectra of the gastrocnemius-plantaris-soleus (GPS muscles group at rest and during electric stimulation. Wet weight and maximum tension of the whole GPS muscles group were also measured. From the MRS measurements, the muscle oxidative capacity in the OVX group was significantly lower than that in the Sham group (p < 0.05 at both one and four weeks after surgery. The muscle's wet weight one week after surgery in the OVX group was the same as the Sham group, while four weeks after surgery it was significantly greater than that in the Sham group (p < 0.05. There were no significant differences in maximum tension among the groups. In conclusion, in adult rats the oxidative capacity decreased due to ovariectomy despite the increase in muscle weight. It is suggested that the muscular endurance capacity in female adult athletes with sports related amenorrhea may deteriorate.

    This study reviews the treatment of facial trauma between October 1986 and December 1990 at a major pediatric referral center. The mechanism of injury, location and pattern of facial fractures, pattern of facial injury, soft tissue injuries, and any associated injuries to other organ systems were recorded, and fracture management and perioperative complications reviewed. The study population consisted of 137 patients who sustained 318 facial fractures. Eighty-one patients (171 fractures) were seen in the acute stage, and 56 patients (147 fractures) were seen for reconstruction of a secondary deformity. Injuries in boys were more prevalent than in girls (63% versus 37%), and the 6- to 12-year cohort made up the largest group (42%). Most fractures resulted from traffic-related accidents (50%), falls (23%), or sports-related injuries (15%). Mandibular (34%) and orbital fractures (23%) predominated; fewer midfacial fractures (7%) were sustained than would be expected in a similar adult population. Three quarters of the patients with acute fractures required operative intervention. Closed reduction techniques with maxillomandibular fixation were frequently chosen for mandibular condyle fractures and open reduction techniques (35%) for other regions of the facial skeleton. When open reduction was indicated, plate-and-screw fixation was the preferred method of stabilization (65%). The long-term effects of the injuries and the treatment given on facial growth remain undetermined. Perioperative complication rates directly related to the surgery were low.

    Avulsion fractures and chronic avulsion injuries of the knee are common lesions in sports-related trauma, especially among adolescents. Magnetic resonance imaging may prove useful in detecting and characterizing such lesions, and has several advantages with regard to other imaging modalities. We review, illustrate, and discuss the MR imaging features of some of the more frequent avulsion fractures and chronic avulsion injuries of the knee, including avulsion fractures of the cruciate ligaments, avulsion fractures of lateral and medial stabilizers, avulsion fractures and chronic avulsion injuries of the extensor mechanism, and avulsive cortical irregularities of the distal femur. The role of MR imaging in evaluating such lesions is emphasized. (orig.)

    Full Text Available Background: Many diseases present themselves in oral and maxillofacial regions and various modalities may be applied for their diagnosis, including intraoral and panoramic radiography, ultrasonography (USG, computer tomography, magnetic resonance imaging, and nuclear medicine methods such as positron emission tomography. Of these modalities, USG is easy to-use for the detection of non-invasive and soft tissue related diseases in oral and maxillofacial regions. USG plays an important role in analyzing normal and abnormal structures. In particular, in oral and maxillofacial regions, the USG may be clinically applied to evaluate lymph nodes, subcutaneous, and oral cavity-related diseases. Aims: The aim was to correlate the findings of USG and histopathology for the diagnosis of oral and maxillofacial pathology and to evaluate whether USG can be used as an adjunct in diagnosing oral and maxillofacial pathology. Materials and Methods: A total of 10 clinically diagnosed patients with intraoral cancerous growths, swellings in maxillary and neck region were included in this study. Incision biopsy was obtained for confirming provisional clinical diagnosis. The selected cases were advised USG. All patients were then posted either for hemi-glossectomy, hemi-mandibulectomy, and partial maxillectomy with or without radical neck dissection. Statistical Analysis: Student′s t-test and coefficient of correlation was used to statistically analyze significant relationship of both the methods. Result: In all 10 cases, USG correlated well with histopathology findings, it could also delineate tumor extent and measure tumor thickness. Conclusion: USG is an excellent method for the diagnosis of soft tissue lesions and can be used as an adjunct in diagnosing oral and maxillofacial pathology.

    Airway management in patients with complex maxillofacial injuries is a challenge to anesthesiologists. Submental intubation is a useful technique that is less invasive than tracheostomy in securing the airways where orotracheal and nasotracheal intubation cannot be performed. This procedure avoids the use of tracheostomy and bypasses its associated morbidities. A flexible and kink-resistant reinforced endotracheal tube with detachable universal connector is commonly used for submental intubation. Herein, we report cases involving submental intubation using a reinforced endotracheal tube with a non-detachable universal connector in patients with complex maxillofacial injuries. PMID:27924286

    Isolated fractures of the hamulus, formerly considered rare, are being seen more frequently. Many of these injuries are sports related, particularly in golf, tennis, racquetball and baseball players. Failure to make an early diagnosis can result in severe pain and sometimes incapacitating disability. The authors studied the clinical and radiological findings in 12 patients who had fracture of the hook of the hamate. The proposed three radiographic signs of fracture that are readily seen on routine PA projections: absence of the hook of the hamate; sclerosis of the hook; and lack of cortical density, i.e., barely visible outline, of the hamulus

    To determine the incidence of mandibular ramus fractures in KLE's PK Hospital and to analyze the outcome of open reduction and internal fixation of these fractures. Using a retrospective study design, records of all trauma patients who reported to the Department of Oral and Maxillofacial Surgery, KLE's PK Hospital Belgaum, between the years January 2006 to October 2011 was obtained from the medical records office. The data variables that were analyzed were the name, age, sex, cause of injury, pretreatment occlusion, treatment given, period of MMF and post-treatment occlusion. Total number of mandibular fracture cases was 298. Ramus fractures were 10 in number which accounted for 3.3% of fractures. The age range of these 10 patients was seen to be between 20 to 80 years with the average age being 35.6 years. Of these 10 patients, 9 were male and 1 was female and 7 patients were treated by open reduction and internal fixation and the remaining 3 by closed reduction. The average period of MMF was 3 days for the patients who underwent open reduction and internal fixation. There was improvement in occlusion in all 10 patients post-treatment and there was no complication reported in any of the cases. Ramus fractures accounted for 3.3% of all mandibular fractures. Open reduction and internal fixation of ramus fractures ensures adequate functional and anatomic reduction. This study makes an attempt to throw a light on the increasing incidence of ramus fractures and a successful management of these fractures by open reduction and internal fixation.

    Previous studies in various medical specialties have shown that fewer than 50% of abstracts presented at meetings are subsequently published. The purpose of the present study was to determine the publication rate of abstracts presented at the annual meetings of the American Association of Oral and Maxillofacial Surgeons. The titles and authors of the abstracts from all oral abstract session presentations and posters by American contributors were collected from the Final Programs of the American Association of Oral and Maxillofacial Surgeons annual meetings for 2006 to 2009. A PubMed search for published articles through December 2010 was then performed using the authors' names, abstract titles, and key words. A total of 311 abstract presentations were done at the 4 annual meetings. Of these, only 85 (24%) were subsequently published. No difference was found between abstracts from oral or poster presentations. Most of the articles were published in the Journal of Oral and Maxillofacial Surgery. Because of deficiencies that can occur in abstracts and the need to disseminate the information they contain, it is important to take the appropriate measures to ensure that full articles are subsequently published.

    Full Text Available Background: The pattern of craniofacial soft-tissue injuries occurring either in isolation or in association with fractures vary in different societies and is multiply influenced. The effects are enormous because of the prominence of the face; therefore, the purpose of this study was to document any changing pattern, severity and management of these craniofacial injuries in our center. Patients and Method: Cranio-maxillofacial region was classified into upper, middle and lower face. The cause, type, and site of the injuries were documented. Gunshot injuries were further categorized as penetrating, perforating or avulsions. Further, classification of injuries into mild, moderate, and severe was carried out based on multiple factors. Result: A total of 126 patients with soft-tissue injuries presented to our hospital out of which 85 (67.5% were males and 41 (32.5 were females. The age range of the patients was between 10 months and 90 years with a mean ± SD of 26.4 ± 15.5 years. Road traffic accident was the most common etiology of which vehicular accidents constituted 50 (54.9% and the motorcycle was 2 (2.2%.

    On-field management and return-to-play guidelines aim to ensure the identification and appropriate management of the concussed athlete. Compliance with current guidelines in many settings is unknown. We assessed whether key components of current concussion guidelines are being followed in child athletes. Prospective observational study. Data were collected from children (5-18 years) presenting to a paediatric emergency department with sport-related concussion via researcher-administered surveys in the emergency department and during a follow up phone call. On hospital discharge all patients received a return to sports fact sheet based on the International Concussion in Sports Group. Ninety-three had sustained a concussion (mean age 12.7 (±0.27) years, 83% male). Sports played included Australian Football (47%), soccer (12%), rugby (9%) basketball (8%), other (25%). 82% participated in organised sports. Concussive signs or symptoms included loss of consciousness (41%), disorientation (36%), vomiting (23%), amnesia (30%), headache (60%). For concussive injury in organised sports (n=76), overall 42% were not managed according to recommended guidelines: 19% were not immediately removed from play, 29% were allowed to return to play on the same day and 27% were not assessed by qualified personnel. 93% of parents and 96% of patients were unaware of concussion or return-to-play guidelines from their organisations. Overall, 72% were compliant with provided return-to-play guidelines. Many children with sports related-concussion are not formally assessed on-field and continue to play. On-field concussion management and return to play practices are often suboptimal. Awareness and education of coaches, teachers, parents and children need to be improved.

    Younger age has been hypothesized to be a risk factor for prolonged recovery after sport-related concussion, yet few studies have directly evaluated age differences in acute recovery. To compare clinical recovery patterns for high school and collegiate athletes. Prospective cohort study. Large, multicenter prospective sample collected from 1999-2003 in a sports medicine setting. Concussed athletes (n = 621; 545 males and 76 females) and uninjured controls (n = 150) participating in high school and collegiate contact and collision sports (79% in football, 15.7% in soccer, and the remainder in lacrosse or ice hockey). Participants underwent evaluation of symptoms (Graded Symptom Checklist), cognition (Standardized Assessment of Concussion, paper-and-pencil neuropsychological tests), and postural stability (Balance Error Scoring System). Athletes were evaluated preinjury and followed serially at several time points after concussive injury: immediately, 3 hours postinjury, and at days 1, 2, 3, 5, 7, and 45 or 90 (with neuropsychological measures administered at baseline and 3 postinjury time points). Comparisons of concussed high school and collegiate athletes with uninjured controls suggested that high school athletes took 1 to 2 days longer to recover on a cognitive (Standardized Assessment of Concussion) measure. Comparisons with the control group on other measures (symptoms, balance) as well as direct comparisons between concussed high school and collegiate samples revealed no differences in the recovery courses between the high school and collegiate groups on any measure. Group-level recovery occurred at or before 7 days postinjury on all assessment metrics. The findings suggest no clinically significant age differences exist in recovery after sport-related concussion, and therefore, separate injury-management protocols are not needed for high school and collegiate athletes.

    We describe the techniques available for retention of implant-supported prostheses: bar-clips, O-rings, and magnets. We present reported preferences and, although this is limited by the heterogeneity of methods used and patients studied, we hope we have identified the best retention systems for maxillofacial prosthetic implants. If practitioners know the advantages and disadvantages of each system, they can choose the most natural and comfortable prosthesis. We searched the PubMed and Scopus databases, and restricted our search to papers published 2001-13. MeSH terms used were Maxillofacial prosthesis and Craniofacial prosthesis OR Craniofacial prostheses. We found a total of 2630 papers, and after duplicates had been removed we analysed the rest and found 25 papers for review. Of these, 12 were excluded because they were case reports or non-systematic reviews. Of the remaining 13, 10 described group analyses and seemed appropriate to find practitioner's choices, as cited in the abstract (n=1611 prostheses). Three papers did not mention the type of prosthetic connection used, so were excluded. The most popular choices for different conditions were analysed, though the sites and retention systems were not specified in all 10 papers. The bar-clip system was the most used in auricular (6/10 papers) and nasal prostheses (4/10). For the orbital region, 6/10 favoured magnets. Non-osseointegrated mechanical or adhesive retention techniques are the least expensive and have no contraindications. When osseointegrated implants are possible, each facial region has a favoured system. The choice of system is influenced by two factors: standard practice and the abilities of the maxillofacial surgeon and maxillofacial prosthetist.

    Additive manufacturing is the process of joining materials to create objects from digital 3-dimensional (3D) model data, which is a promising technology in oral and maxillofacial surgery. The management of lost craniofacial tissues owing to congenital abnormalities, trauma, or cancer treatment poses a challenge to oral and maxillofacial surgeons. Many strategies have been proposed for the management of such defects, but autogenous bone grafts remain the gold standard for reconstructive bone surgery. Nevertheless, cell-based treatments using adipose stem cells combined with osteoconductive biomaterials or scaffolds have become a promising alternative to autogenous bone grafts. Such treatment protocols often require customized 3D scaffolds that fulfill functional and esthetic requirements, provide adequate blood supply, and meet the load-bearing requirements of the head. Currently, such customized 3D scaffolds are being manufactured using additive manufacturing technology. In this review, 2 of the current and emerging modalities for reconstruction of oral and maxillofacial bone defects are highlighted and discussed, namely human maxillary sinus floor elevation as a valid model to test bone tissue-engineering approaches enabling the application of 1-step surgical procedures and seeding of Good Manufacturing Practice-level adipose stem cells on computer-aided manufactured scaffolds to reconstruct large bone defects in a 2-step surgical procedure, in which cells are expanded ex vivo and seeded on resorbable scaffolds before implantation. Furthermore, imaging-guided tissue-engineering technologies to predetermine the surgical location and to facilitate the manufacturing of custom-made implants that meet the specific patient's demands are discussed. The potential of tissue-engineered constructs designed for the repair of large oral and maxillofacial bone defects in load-bearing situations in a 1-step surgical procedure combining these 2 innovative approaches is

    To investigate the distribution and drug resistance of anaerobic bacteria in the patients with oral and maxillofacial infection. Aerobic and anaerobic bacteria cultures from 61 specimens of pus from the patients with oral and maxillofacial infection in the Department of Oral and Maxillofacial Surgery, Peking University School of Stomatology were identified. The culture type was evaluated by API 20A kit and drug resistance test was performed by Etest method. The clinical data and antibacterial agents for the treatment of the 61 cases were collected, and the final outcomes were recorded. The bacteria cultures were isolated from all the specimens, with aerobic bacteria only in 6 cases (9.8%), anaerobic bacteria only in 7 cases (11.5%), and both aerobic and anaerobic bacteria in 48 cases (78.7%). There were 55 infected cases (90.2%) with anaerobic bacteria, and 81 anaerobic bacteria stains were isolated. The highest bacteria isolation rate of Gram positive anaerobic bacteria could be found in Peptostreptococcus, Bifidobacterium and Pemphigus propionibacterium. No cefoxitin, amoxicillin/carat acid resistant strain was detected in the above three Gram positive anaerobic bacteria. The highest bacteria isolation rate of Gram negative anaerobic bacteria could be detected in Porphyromonas and Prevotella. No metronidazole, cefoxitin, amoxicillin/carat acid resistant strain was found in the two Gram negative anaerobic bacteria. In the study, 48 patients with oral and maxillofacial infection were treated according to the results of drug resistance testing, and the clinical cure rate was 81.3%. Mixed aerobic and anaerobic bacteria cultures are very common in most oral and maxillofacial infection patients. Anaerobic bacteria culture and drug resistance testing play an important role in clinical treatment.

    Maxillofacial fractures are uncommon in the pediatric population, and their treatment is unique due to the psychological, physiological, developmental and anatomical characteristics of children. We present the case of a boy who was treated in an outpatient dental clinic using a lingual splint for the reduction, stabilization and fixation of a mandibular body fracture. This technique is a reliable, noninvasive procedure that dentists may consider in selected cases by referral to an oral and maxillofacial surgeon. It also limits the discomfort and morbidity that can be associated with maxillomandibular fixation or open reduction and internal fixation in pediatric patients.

    Blunt trauma to the temporal region can cause fracture of the skull base, loss of hearing, vestibular symptoms and otorrhoea. The most common causes of blunt trauma to the ear and surrounding area are motor vehicle accidents, violent encounters, and sports-related accidents. We present an obscure case of a man who was struck in the ear by a flying fish while wading in the sea with resulting temporal bone fracture, sudden deafness, vertigo, cerebrospinal fluid otorrhoea, and pneumocephalus.

    This systematic review investigates the most common indications, treatments, and outcomes of surgical navigation (SN) published from 2010 to 2015. The evolution of SN and its application in oral and maxillofacial surgery have rapidly developed over recent years, and therapeutic indications are discussed. A systematic search in relevant electronic databases, journals, and bibliographies of the included articles was carried out. Clinical studies with 5 or more patients published between 2010 and 2015 were included. Traumatology, orthognathic surgery, cancer and reconstruction surgery, skull-base surgery, and foreign body removal were the areas of interests. The search generated 13 articles dealing with traumatology; 5, 6, 2, and 0 studies were found that dealt with the topics of orthognathic surgery, cancer and reconstruction surgery, skull-base surgery, and foreign body removal, respectively. The average technical system accuracy and intraoperative precision reported were less than 1 mm and 1 to 2 mm, respectively. In general, SN is reported to be a useful tool for surgical planning, execution, evaluation, and research. The largest numbers of studies and patients were identified in the field of traumatology. Treatment of complex orbital fractures was considerably improved by the use of SN compared with traditionally treated control groups. SN seems to be a very promising addition to the surgical toolkit. Planning details of the surgical procedure in a 3-dimensional virtual environment and execution with real-time guidance can significantly improve precision. Among factors to be considered are the financial investments necessary and the learning curve. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. All rights reserved.

    Three-dimensional CT measurement is put in practice in order to grasp the pathological condition on diseases such as the temporomandibular joint disorder, maxillofacial anomaly, jaw deformity, or fracture which cause the morphologic changes of the maxillofacial bones. On the 3D measurement, the unique system that is obtained by volume rendering 3D images with a simultaneous reference of axial images combined with coronal and sagittal multi-planar reconstruction (MPR) images (we call this MPR referential method), is employed in order to define the measurement points. Our purpose in this report is to indicate the usefulness of this unique method by comparing with the common way to define the measurement points on only 3D reconstruction images without consulting of MPR images. Clinical CT data obtained from a male patient with skeletal malocclusion was used. Contiguous axial images were reconstructed at 4 times magnification, with a reconstruction interval of 0.5 mm, focused on the temporomandibular joint region in his left side. After these images were converted to Digital Imaging and Communications in Medicine (DICOM) format and sent to personal computer (PC), 3D reconstruction image was created using free 3D DICOM medical image viewer. The coordinates of 3 measurement points (the lateral and medial pole of the mandibular condyle, and the left foramen ovale) were defined with MPR images (MPR coordinates) as reference coordinates, and then the coordinates that were defined on only 3D reconstruction image without consulting to MPR images (3D coordinates) were compared to those of MPR coordinates. Three examiners were engaged independently 10 times for every measurement point. In our result, there was no correspondence between 3D coordinates and MPR coordinates, and contribution of 3D coordinates showed a variety in every measurement point and in every observer. We deemed that ''MPR referential method'' is useful to assess the location of the target point of anatomical

    Personal experience in percutaneous maxillary nerve block anesthesia in association with transmucosal anesthesia of the sphenopalatine ganglion in oral and maxillofacial surgery, is presented. Six Caldwell-Luc, 9 anthrotomies and biopsies of maxillary sinus, 8 removals of extensive odontogenic cysts and 12 surgical maxillary expansions were performed from 1994 to 1996 at our Department. Maxillary transcutaneous nerve block in association with transmucosal anesthesia of the sphenopalatine ganglion were performed. Carbocaine without adrenaline in association with NaCO3 1/10 for maxillary nerve block anesthesia and lidocaineoprilocaine cream (EMLA) for transmucosal anesthesia were employed. Intra- and post-operative pain were evaluated by visual analogue scale in all the patients. Anesthesiological procedures revealed to be effective in all surgical interventions and postoperative analgesia allowed easier pain control. The simplicity of execution, the effective pre- and postoperative anesthesia and the absence of side effects make this procedure particularly indicated in oral and maxillofacial surgery.

    Descriptions of several oral, maxillofacial and dental conditions/diseases exist for a variety of captive large felids, but little is reported on the pathology of free roaming large felids. Apart from focal palatine erosions (FPEs) as initially described by Fitch and Fagan (1982) and some reference to absent incisor teeth, few data exist on diseases affecting the oral, maxillofacial and dental structures of cheetahs (Acinonyx jubatus), regardless of their captivity status. This study reports 18 different conditions affecting the teeth, bone and oral cavity soft tissue of cheetahs, based on initial assessment of 256 animals over 11 years (2002-2012) in South Africa and Namibia. This report excludes oral tumours or FPEs, but includes several acquired and developmental conditions never described before. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Orthognathic surgery is this field of the maxillofacial surgery which aims to reposition the jaws or some segments of these jaws when masticatory dysfunctions are evident. This tridimensional repositioning in the craniofacial skeleton allows to restore the masticatory function by means of osteotomies, which must be followed either by preoperative simulated bony displacements or by callus bone distraction. Not only are the functional benefits evident on the dental, articular and neuromuscular levels, but also a facial esthetic harmony can almost be obtained.

    As CT values of hard tissues would pose problems in the application of CT to the maxillofacial area, attenuation coefficients of each oral hard tissue were examined based on the existing data, and the linearity in the area of high x-ray attenuation was examined. We thought that a new contrast scale suitable for each area should be established for measurements of CT values of tissues of high x-ray attenuation such as teeth. (Chiba, N.)

    To determine the perceived utility and demand for the application of telemedicine for improved patient care between nonsurgical dental practitioners (GPs) and oral and maxillofacial surgeons (OMS). Two distinct questionnaires were made, one for GPs and one for OMSs. The GP questionnaire was sent to practicing Virginia Dental Association members on an e-mail list (approximately 2,200). The OMS questionnaire was sent by the Virginia Society of Oral Maxillofacial Surgery to members on an e-mail list (approximately 213). Questionnaires included questions about access to care, benefits of telemedicine consultations, reliability of telemedicine consultations, and perceived barriers against and opportunities for the implementation of telemedicine. The questionnaire was completed by 226 GP and 41 OMS respondents. There was a significant difference among responses of GPs based on practice location: rural patients had a longer average time from referral to OMS consultation (P = .003), rural patients traveled longer distances (P telemedicine, whereas OMS respondents were more neutral. GPs responded they would refer more patients (4.4) if consultations could be performed by telemedicine. OMSs agreed that more referrals would influence their decision to provide telemedicine consultations (51%). Practitioners had neutral perceptions about the reliability of telemedicine. OMS respondents agreed they would implement telemedicine in their practice if it provided equally good consultations as in-office visits. According to the present findings, telemedicine could be an important step in the right direction for overcoming current issues with patient access to care and increasing health care costs. The benefits of telemedicine technology have been documented and will continue to be seen with wider application of its use in other areas of health care such as oral and maxillofacial surgery.

The first independent Department was separated from the Department of Oral Surgery at Seoul National University in 1963. Nowadays, there are 6 national and 5 private dental schools in South Korea. Each dental school has a Department of Oral and Maxillofacial Radiology, which fulfills its role in student education and clinical service. What is specially noteworthy is that 8 of the 11 dental schools have changed or will change from the 2+4 year system to 4+4 year system (postgraduate course). The curriculum has also been or is being amended according to this change. Although the contents of courses for Oral and Maxillofacial Radiology are not much different among dental schools, the methods and structure of education are various. We have to do a systematic and comprehensive analysis of the present educational methods and structure of Oral and Maxillofacial Radiology and need to seek the new and more suitable ones based on competency.

    Oral and maxillofacial surgery, which involves several sharp instruments and fixation materials, is consistently at a high risk for cross-contamination due to perforated gloves, but it is unclear how often such perforations occur. This study aimed to address this issue. The frequency of the perforation of surgical gloves (n=1436) in 150 oral and maxillofacial surgeries including orthognathic surgery (n=45) was assessed by the hydroinsufflation technique. Orthognathic surgery had the highest perforation rate in at least 1 glove in 1 operation (91.1%), followed by cleft lip and palate surgery (55.0%), excision of oral soft tumour (54.5%) and dental implantation (50.0%). The perforation rate in scrub nurses was 63.4%, followed by 44.4% in surgeons and first assistants, and 16.3% in second assistants. The odds ratio for the perforation rate in orthognathic surgery versus other surgeries was 16.0 (95% confidence interval: 5.3-48.0). The protection rate offered by double gloving in orthognathic surgery was 95.2%. These results suggest that, regardless of the surgical duration and blood loss in all fields of surgery, orthognathic surgery must be categorized in the highest risk group for glove perforation, following gynaecological and open lung surgery, due to the involvement of sharp objects.

    To determine the relation between sleep quantity and sleep disturbances on symptoms and neurocognitive ability during the acute phase (sports-related concussion (SRC; >21d). Prospective inception cohort study. General community setting of regional middle and high schools. A sample (N=971) including youth athletes with SRC (n=528) and controls (n=443) (age, 10-18y). Not applicable. Athletes completed the Immediate Post-Concussion Assessment and Cognitive Testing battery. Partial correlation analyses and independent t tests were conducted to assess sleep quantity the night before testing. Multivariate analysis of covariance was used to assess sleep disturbances and their interaction with age. Less sleep quantity was correlated with greater report of cognitive (P=.001) and neuropsychological (P=.024) symptoms specific to prolonged recovery from SRC. Sleep disturbances significantly affect each migraine, cognitive, and neuropsychological symptoms (Psleep disturbances and age (P=.04) at >21 days post-SRC. Findings emphasize that the continued presence of low sleep quantity and sleep disturbances in youth athletes with SRC should be a specific indicator to health professionals that these athletes are at an increased risk of protracted recovery. Further research should identify additional factors that may interact with sleep to increase the risk of protracted recovery. Copyright © 2018 American Congress of Rehabilitation Medicine.

    Intercollegiate athletes report greater alcohol consumption and more alcohol-related problems than their non-athlete peers. Although college athletes share many of the same problems faced by non-athletes, there are some consequences that are unique to athletes. Studies have demonstrated that alcohol negatively affects athletic performance including increased dehydration, impeded muscle recovery, and increased risk for injury. Beyond risk factors for alcohol misuse that may affect college students in general, research has begun to examine risk factors that are unique to collegiate athletes. For example, research has found that off-season status, the leadership role, and athlete-specific drinking motives are associated with increased alcohol use. Given these findings, it is possible that other athlete-specific variables influence alcohol misuse. One such variable may be sport achievement orientation. The purpose of the current study was to examine the relationship between sport achievement orientation and alcohol outcomes. Given previous research regarding seasonal status and gender, these variables were examined as moderators. Varsity athletes (n=263) completed the Sport Orientation Questionnaire, which assesses sport-related achievement orientation on three scales (Competitiveness, Win Orientation, and Goal Orientation). In addition, participants completed measures of alcohol use and alcohol-related problems. Results indicated that Competitiveness, Win Orientation, and Goal Orientation were all significantly associated with alcohol use, but not alcohol-related problems. Moreover, these relationships were moderated by seasonal status and gender. These interactions, clinical implications, and limitations are discussed. © 2013.

    In the last decade, evidence regarding chronic pain has developed exponentially. Numerous studies show that many chronic pain populations show specific neuroplastic changes in the peripheral and central nervous system. These changes are reflected in clinical manifestations, like a generalized hypersensitivity of the somatosensory system. Besides a hypersensitivity of bottom-up nociceptive transmission, there is also evidence for top-down facilitation of pain due to malfunctioning of the endogenous descending nociceptive modulatory systems. These and other aspects of modern pain neuroscience are starting to be applied within daily clinical practice. However, currently the application of this knowledge is mostly limited to the general adult population with musculoskeletal problems, while evidence is getting stronger that also in other chronic pain populations these neuroplastic processes may contribute to the occurrence and persistence of the pain problem. Therefore, this masterclass article aims at giving an overview of the current modern pain neuroscience knowledge and its potential application in post-cancer, paediatric and sports-related pain problems.

    Very few studies examined the prevalence and sport-related predictors of disturbed eating attitudes and behaviors (DEABs) among adolescents involved in sport practice, and their results are mixed and inconclusive. These inconsistencies are most likely due to their methodological heterogeneity and to the fact that none of these studies took into consideration the potentially relevant characteristics of the sport practice context. This study attempts to answer this limitation among French adolescents not involved or involved in various sports contexts defined based on their organization, leanness-centration, and competitive level. Participants were 335 adolescents involved in sport practice, and 435 adolescents not involved in any form of regular sport practice. The DEABs were measured using the Eating Attitudes Test-26. Global results do not showed any significant association between the status of the participants and DEAB. However, these results drastically changed when we considered the potential moderating role of sex and age on these relations. Indeed, sports involvement in general, and involvement in leanness and competitive sports were found to exert sex- and age-differentiated effects on the risks of presenting clinically significant levels of DEAB. This study suggests the importance of monitoring, preventive, and early intervention mechanisms within the context of practice, particularly for adolescent girls. © 2013 John Wiley & Sons A/S.

    To review the diagnostic tests and investigations used in the management of sports concussion, in the adult and paediatric populations, to (a) monitor the severity of symptoms and deficits, (b) track recovery and (c) advance knowledge relating to the natural history and neurobiology of the injury. Qualitative literature review of the neuroimaging, balance testing, electrophysiology, blood marker and concussion literature. PubMed and Medline databases were reviewed for investigations used in the management of adult and paediatric concussion, including structural imaging (computerised tomography, magnetic resonance imaging, diffusion tensor imaging), functional imaging (single photon emission computerised tomography, positron emission tomography, functional magnetic resonance imaging), spectroscopy (magnetic resonance spectroscopy, near infrared spectroscopy), balance testing (Balance Error Scoring System, Sensory Organization Test, gait testing, virtual reality), electrophysiological tests (electroencephalography, evoked potentials, event related potentials, magnetoencephalography, heart rate variability), genetics (apolipoprotein E4, channelopathies) and blood markers (S100, neuron-specific enolase, cleaved Tau protein, glutamate). For the adult and paediatric populations, each test has been classified as being: (1) clinically useful, (2) a research tool only or (3) not useful in sports-related concussion. The current status of the diagnostic tests and investigations is analysed, and potential directions for future research are provided. Currently, all tests and investigations, with the exception of clinical balance testing, remain experimental. There is accumulating research, however, that shows promise for the future clinical application of functional magnetic resonance imaging in sport concussion assessment and management.

  5. Atypical femoral neck stress fracture in a marathon runner: a case report and literature review.

    LENUS (Irish Health Repository)

    2012-02-01

    BACKGROUND: Femoral neck stress fractures are relatively rare and may present as sports-related injuries. The presentation is variable, and prompt diagnosis facilitates the earliest return to pre-morbid functional activity levels. Delayed detection may precipitate femoral non-union or avascular necrosis, resulting in long-term functional deficit. AIMS: We present the case of a basicervical femoral neck stress fracture occurring in a 23-year-old marathon runner. The pathophysiology and practical management issues related to this unusual injury pattern are discussed. CONCLUSION: The growing interest in amateur athletic activities should raise the index of suspicion for stress fractures of the femoral neck in healthy adults with atypical hip pain. Increased levels of patient education and physician awareness can reduce the incidence of long-term morbidity in cases of this unusual sports-related injury.

An open reduction and internal fixation  (ORIF and enucleation of globe occular sinistra was performed.  Intraoral vestibular incision is made in the upper and lower vestibular region. Mucoperiosteal flap elevation of vestibular will exposure of the anterior maxilla and mandibular fractures. Intermaksilary fixation within 3 week and restore aesthetic with prosthesis fitting eyeball and denture. Discusion. The goal of  treatment of  panfacial fracture is to restore both the functions and pre-injury 3-dimensional facial contours. To achieve this goal two common  sequences of management of Panfacial fractures are proposed, “Bottom up and inside out” or “Top down and outside in”. Other sequences exist but there are variations of these two major approaches. Conclusion. A minimally invasive approach to  the fracture site is an alternative method  to manage panfacial fracture with a simple, effective and lower complication rate.

    Cone-beam computed tomography (CBCT) is making inroads into dental practice worldwide, both in terms of adding the third dimension to diagnosis, and also in terms of enabling image-guided treatment strategies. This article reports trends in the early referral pattern of patients to a CBCT facility in the United States. With institutional review board approval, a retrospective study was made of sequential CBCT radiographic reports made by a specialist oral and maxillofacial radiology service from May 2004 through January 2006 (n=329). Demographic and referral data were extracted from the reports. Descriptive statistics identified referral patterns, trends, and indications for CBCT. Comparisons were made with the Rogers' Product Innovation Adoption curve. The mean age of referred patients was 45±21 years, and there was a predominance of women (62%). Oral and maxillofacial surgeons (51%) and periodontology specialists (17%) made most patient referrals. The listed reasons for CBCT referrals were dental implant planning (40%), suspected surgical pathology (24%), and temporomandibular joint analysis (16%). Other uses included planning extraction of impacted teeth and orthodontic assessment. Over the period of the study, the numbers of pathology diagnosis cases remained relatively constant, while adoption of CBCT for dental implant planning followed closely the first three stages of the Rogers' Product Innovation Adoption curve. Alongside this increased CBCT adoption for dental implant planning, there was an associated increased demand for use of Digital Imaging and Communications in Medicine (DICOM) image sets for laser modeling and provision of surgical guides. Diagnosis will probably remain a constant source of referral for CBCT examination by oral and maxillofacial radiologists. Nevertheless, more specialized applications such as laser-guided model fabrication and image-guided surgery are expanding indications for CBCT referrals by dentists and also expanding the

    Full Text Available Introduction. The frequency of patellar fractures is approximately 0.5% to 1.5% of all skeletal injuries. The following types of fractures can be distinguished: avulsive, transverse, longitudinal, and comminuted. In cases of displacement of more than 2–3 mm and quadriceps tendon injuries open reduction and internal fixation with the restoration of the articular surface is more preferable. In cases of longitudinal fractures, arthroscopy is regarded as a highly effective method of surgical treatment. Materials and methods. Using arthroscopy, we have operated on 4 patients with longitudinal fracture of the patella. The average age of the injured persons was 15.4 years (14–17. These were 3 males and 1 female. All patients had sport-related injuries. Because of the longitudinal fracture of the patella, the lateral knee extensor mechanism remained intact, and arthrosopy-assisted surgical intervention with closed reposition of fragments and transcutaneous wire fixation was performed without wire suturing. Results and discussion. Minimal invasiveness, the possibility of visual control over the recovery quality of patellar surface, the reliability of fragment fixation, and a significant reduction in the subsequent rehabilitation make arthroscopy a highly effective method of surgical treatment for patellar fractures.

    Baseball and softball are leading causes of sports-related facial trauma in the United States. We review our institutional experience (Strong Memorial Hospital, Rochester, NY) with these injuries and discuss measures to reduce their incidence. We review our institutions experience with facial fractures sustained during the course of a softball or baseball game over a 12-year period. A total of 38 patients were identified and medical records analyzed for patient demographics, type of impact, and fracture location. The male-to-female ratio was 3.2:1; mean age was 24.2 years, with 17 (45%) of the injuries occurring in the pediatric population. The majority of the injuries were caused by direct impact with the ball (68%), while player-player collisions (18%) and impact from a swung bat (13%) were responsible for the remaining injuries. There were a total of 39 fractures; 18 fractures (46%) involved the midface (level 2), skull (level 1) fractures accounted for 12 (31%), while 9 (23%) were mandibular (level 3) fractures. With 68% of the injuries resulting from a ball impact, we endorse the recommendations of the Consumer Product Safety Commission for the use of low-impact National Operating Committee on Standards for Athletic Equipment-approved baseballs and softballs for youth and recreational leagues.

    This review aims to provide information on the time athletes will take to resume sports activity following ankle fractures. We systematically searched Medline (PubMED), EMBASE, CINHAL, Cochrane, Sports Discus and Google scholar databases using the combined keywords 'ankle fractures', 'ankle injuries', 'athletes', 'sports', 'return to sport', 'recovery', 'operative fixation', 'pinning', 'return to activity' to identify articles published in English, Spanish, French, Portuguese and Italian. Seven retrospective studies fulfilled our inclusion criteria. Of the 793 patients, 469 (59%) were males and 324 (41%) were females, and of the 356 ankle fractures we obtained information on, 338 were acute and 18 stress fractures. The general principles were to undertake open reduction and internal fixation of acute fractures, and manage stress fractures conservatively unless a thin fracture line was visible on radiographs. The best timing to return to sports after an acute ankle fracture is still undefined, given the heterogeneity of the outcome measures and results. The time to return to sports after an acute stress injury ranged from 3 to 51 weeks. When facing athletes with ankle fractures, associated injuries have to be assessed and addressed to improve current treatment lines and satisfy future expectancies. The best timing to return to sports after an ankle fracture has not been established yet. The ideas of the return to activity parameter and surgeon databases including sports-related information could induce research to progress.

    The victim of orofacial cancer is frequently subjected to severe morphological and functional disturbance: a condition which the maxillofacial prosthetist can do much to alleviate through the use of various prosthetic devices. The successful rehabilitation of these patients, however, is often compromised by the presence of psychosocial and other problems, the solution of which extends beyond the limits of a single clinical discipline. The modern approach to orofacial cancer, therefore, is organised within the context of interdisciplinary co-operation: each phase of patient management being planed and executed according to the co-ordinated efforts of the various members of a head and neck cancer team

    Sports-related concussions and repetitive subconcussive exposure are increasingly recognized as potential dangers to paediatric populations, but much remains unknown about the short-term and long-term consequences of these events, including potential cognitive impairment and risk of later-life dementia. This Expert Consensus Document is the result of a 1-day meeting convened by Safe Kids Worldwide, the Alzheimer's Drug Discovery Foundation, and the Andrews Institute for Orthopaedics and Sports Medicine. The goal is to highlight knowledge gaps and areas of critically needed research in the areas of concussion science, dementia, genetics, diagnostic and prognostic biomarkers, neuroimaging, sports injury surveillance, and information sharing. For each of these areas, we propose clear and achievable paths to improve the understanding, treatment and prevention of youth sports-related concussions.

    Fractures of the mandible are relatively less frequent in children when compared to adults. The anatomic features of children are protected. Children have a higher adaptation to maxillofacial fractures compared to adults. Treatment principles of mandibular fractures in children differ from that of adults due to concerns regarding mandibular growth and the developing dentition. A case of a 6-year-old boy with fractured mandibular symphysis managed by closed reduction using a vacuum formed thermoplastic splint and circummandibular wiring is presented. This article also provides a review of the literature regarding the management of mandibular fracture in young children.

    Adherence to rehabilitation is widely accepted as vital for recovery and return to play following sports injuries. Medical management of concussion is centered around physical and cognitive rest, a theory largely based on expert opinion, not empirical evidence. Current research on this topic focuses on factors that are predictive of adherence to rehabilitation, but fails to examine if patient adherence leads to a better outcome. The purpose of this study was to determine the adherence tendencies of adolescents to treatment recommendations provided by a sports-medicine physician after a concussion and to determine if adherence to each recommendation was a predictor of treatment duration. Observational. Participants were enrolled in the study at their initial visit to the Sports-Medicine Center for medical care after a sports-related concussion. Individual treatment recommendations provided by a sports-medicine physician for concussion were recorded over the course of each participant's care. Once released from medical care, each participant was contacted to complete an online questionnaire to measure self-reported adherence tendencies to each treatment recommendation. Adherence was measured by two constructs: 1) the reported receptivity to the recommendation and 2) the frequency of following the recommendation. Exploratory univariate Poisson regression analyses were used to describe the relationship between adherence behaviors and the number of days of treatment required before the participant was returned to play. Fifty-six questionnaires were completed, by 30 male and 26 female adolescent athletes. The self-reported adherence tendencies were very high. None of the measures of adherence to the treatment recommendations were significant predictors of the number of days of treatment; however, there was a clear tendency in five of the six rest parameters (physical rest, cognitive rest with restrictions from electronics, and cognitive rest with restrictions from school

    Estimated base rates of invalid performance on baseline testing (base rates of failure) for the management of sport-related concussion range from 6.1% to 40.0%, depending on the validity indicator used. The instability of this key measure represents a challenge in the clinical interpretation of test results that could undermine the utility of baseline testing. To determine the prevalence of invalid performance on baseline testing and to assess whether the prevalence varies as a function of age and validity indicator. This retrospective, cross-sectional study included data collected between January 1, 2012, and December 31, 2016, from a clinical referral center in the Midwestern United States. Participants included 7897 consecutively tested, equivalently proportioned male and female athletes aged 10 to 21 years, who completed baseline neurocognitive testing for the purpose of concussion management. Baseline assessment was conducted with the Immediate Postconcussion Assessment and Cognitive Testing (ImPACT), a computerized neurocognitive test designed for assessment of concussion. Base rates of failure on published ImPACT validity indicators were compared within and across age groups. Hypotheses were developed after data collection but prior to analyses. Of the 7897 study participants, 4086 (51.7%) were male, mean (SD) age was 14.71 (1.78) years, 7820 (99.0%) were primarily English speaking, and the mean (SD) educational level was 8.79 (1.68) years. The base rate of failure ranged from 6.4% to 47.6% across individual indicators. Most of the sample (55.7%) failed at least 1 of 4 validity indicators. The base rate of failure varied considerably across age groups (117 of 140 [83.6%] for those aged 10 years to 14 of 48 [29.2%] for those aged 21 years), representing a risk ratio of 2.86 (95% CI, 2.60-3.16; P indicator and the age of the examinee. The strong age association, with 3 of 4 participants aged 10 to 12 years failing validity indicators, suggests that the

    Background The incidence of sport-related concussion (SRC) in high school football is well documented. However, limited prospective data are available regarding how player characteristics and protective equipment affect the incidence of SRC. Purpose To determine whether the type of protective equipment (helmet and mouth guard) and player characteristics affect the incidence of SRC in high school football players. Design Cohort study; Level of evidence, 2. Methods Certified athletic trainers (ATs) at each high school recorded the type of helmet worn (brand, model, purchase year, and recondition status) by each player as well as information regarding players’ demographics, type of mouth guard used, and history of SRC. The ATs also recorded the incidence and days lost from participation for each SRC. Incidence of SRC was compared for various helmets, type of mouth guard, history of SRC, and player demographics. Results A total of 2081 players (grades 9–12) enrolled during the 2012 and/or 2013 football seasons (2287 player-seasons) and participated in 134,437 football (practice or competition) exposures. Of these players, 206 (9%) sustained a total of 211 SRCs (1.56/1000 exposures). There was no difference in the incidence of SRC (number of helmets, % SRC [95% CI]) for players wearing Riddell (1171, 9.1% [7.6%–11.0%]), Schutt (680, 8.7% [6.7%–11.1%]), or Xenith (436, 9.2% [6.7%–12.4%]) helmets. Helmet age and recondition status did not affect the incidence of SRC. The rate of SRC (hazard ratio [HR]) was higher in players who wore a custom mouth guard (HR = 1.69 [95% CI, 1.20–2.37], P football players. Players who had sustained an SRC within the previous 12 months were more likely to sustain an SRC than were players without a history of SRC. Sports medicine providers who work with high school football players need to realize that factors other than the type of protective equipment worn affect the risk of SRC in high school players.

    Full Text Available The purpose of the study was to test the utility of unique panel of blood biomarkers as a means to reflect one’s recovery process after sport-related neurotrauma. We established a panel of biomarkers that reacted positive with CD81 (extracellular vesicle marker and various neuron- and glia-specific antigens [e.g., neurofilament light polypeptide (NF-L, tau, synaptosome-associated protein 25 (SNAP25, glial fibrillary acidic protein, and myelin basic protein]. We first evaluated test–retest reliabilities of brain-derived exosome markers, followed by an application of these markers in eight professional ice hockey players to detect cumulative neuronal burden from a single ice hockey season. During the season, two players were diagnosed with concussions by team physician based on an exhibition of symptoms as well as abnormality in balance and ocular motor testing. One player reached symptom-free status 7 days after the concussion, while the other player required 36 days for symptoms to completely resolve. Blood samples and clinical assessments including balance error scoring system and near point of convergence throughout recovery process were obtained. Biomarkers indicative of axonal damage, neuronal inflammation, and glial activation showed excellent test–retest reliabilities (intraclass correlation coefficient: 0.713–0.998, p’s < 0.01. There was a statistically significant increase in the NF-L marker at post-season follow-up compared to pre-season baseline (Z = −2.100, P = 0.036; however the statistical significance did not withstand Bonferroni correction for multiple comparisons. In concussion cases, neuronal and microglia markers notably increased after concussions, with the unique expression patterns being similar to that of concussion recovery process. These longitudinal data coupled with excellent test–retest reliabilities of novel array of blood biomarkers potentially reflect the damage in neural cell

    The studies of maxillofacial gunshot injuries mainly focused on evaluating the surgical interventions and physical outcomes of the procedures. In this study we aimed to analyze the pre- and post-injury psychiatric status of the patients with self-inflicted gunshot wounds to the face. This study is based on 12 subjects who attempted suicide resulting in extensive maxillofacial injuries using guns placed beneath their chins. The psychiatric evaluation was conducted by interview and using SCID-I, SCID-II, MMPI, Rosenberg Self-Esteem Scale and Suicide Probability Scale. Two subjects were healthy, 1 had bereavement, 6 had current and 5 had previous MDD (major depressive disorder), 2 had dysthymic disorder, 3 had alcohol abuse, 2 had drug abuse and 4 had antisocial personality disorder. The suicidal group was more socially introverted according to MMPI. According to Rosenberg self-esteem subscale, self esteem, the constancy of self respect and depressive mood subtests were statistically significant in the suicide group compared to the healthy controls (P suicide. The changes in the physical facial appearance after the suicide attempt caused impairment of self-esteem and the constancy of self-respect. Similar to other studies, none of our patients reattempted suicide and all tried to return to their pre-injury lifestyle and appeared to accommodate to the stigma of their physical deformities. Early diagnosis and treatment should be considered as a factor to reduce the risk for suicide attempt.

    The aim of this study was to determine the prevalence of burnout syndrome among Brazilian oral and maxillofacial surgeons and its relationship with socio-demographic, clinical, and habit variables. The sample of this study comprised 116 surgeons. The syndrome was quantified using the Maslach Burnout Inventory (General Survey), which defines burnout as the triad of high emotional exhaustion, high depersonalization, and low personal accomplishment. The criteria of Grunfeld et al. were used to evaluate the presence of the syndrome (17.2%). No significant differences between the surgeons diagnosed with and without the syndrome were observed according to age (P=0.804), sex (P=0.197), marital status (P=0.238), number of children (P=0.336), years of professional experience (P=0.102), patients attended per day (P=0.735), hours worked per week (P=0.350), use of alcohol (P=0.148), sports practice (P=0.243), hobbies (P=0.161), or vacation period per year (P=0.215). Significant differences occurred in the variables sex in the emotional exhaustion subscale (P=0.002) and use or not of alcohol in the personal accomplishment subscale (P=0.035). Burnout syndrome among Brazilian surgeons is average, showing a low personal accomplishment. Copyright © 2014 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    Full Text Available Abstract Background The aim of this study was to describe practice activity trends among oral and maxillofacial surgeons in Australia over time. Methods All registered oral and maxillofacial surgeons in Australia were surveyed in 1990 and 2000 using mailed self-complete questionnaires. Results Data were available from 79 surgeons from 1990 (response rate = 73.8% and 116 surgeons from 2000 (response rate = 65.1%. The rate of provision of services per visit changed over time with increased rates observed overall (from 1.43 ± 0.05 services per visit in 1990 to 1.66 ± 0.06 services per visit in 2000, reflecting increases in pathology and reconstructive surgery. No change over time was observed in the provision of services per year (4,521 ± 286 services per year in 1990 and 4,503 ± 367 services per year in 2000. Time devoted to work showed no significant change over time (1,682 ± 75 hours per year in 1990 and 1,681 ± 94 hours per year in 2000, while the number of visits per week declined (70 ± 4 visits per week in 1990 to 58 ± 4 visits per week in 2000. Conclusions The apparent stability in the volume of services provided per year reflected a counterbalancing of increased services provided per visit and a decrease in the number of visits supplied.

  9. Maxillofacial trauma patient: coping with the difficult airway

    2009-05-01

    Full Text Available Abstract Establishing a secure airway in a trauma patient is one of the primary essentials of treatment. Any flaw in airway management may lead to grave morbidity and mortality. Maxillofacial trauma presents a complex problem with regard to the patient's airway. By definition, the injury compromises the patient's airway and it is, therefore, must be protected. In most cases, the patient undergoes surgery for maxillofacial trauma or for other, more severe, life-threatening injuries, and securing the airway is the first step in the introduction of general anaesthesia. In such patients, we anticipate difficult endotracheal intubation and, often, also difficult mask ventilation. In addition, the patient is usually regarded as having a "full stomach" and has not been cleared of a C-spine injury, which may complicate airway management furthermore. The time available to accomplish the task is short and the patient's condition may deteriorate rapidly. Both decision-making and performance are impaired in such circumstances. In this review, we discuss the complexity of the situation and present a treatment approach.

  10. Laser tumor treatment in oral and maxillofacial surgery

    Science.gov (United States)

    Neukam, F. W.; Stelzle, F.

    Cancer treatment is an integral part of oral and maxillofacial surgery. Oral cancer in particular is a highly prevalent neoplasm. Standard treatment for most of the tumors is radical surgery combined with stage-based neo-/adjuvant therapy. Laser surgery has become a reliable treatment option for oral cancer as well as for precancerous lesions. Widely used lasers in oral and maxillofacial tumor surgery are the CO2 laser, the Er:YAG laser, the Nd:YAG laser and the KTM laser. The use of lasers in tumor surgery has several advantages: remote application, precise cutting, hemostasis, low cicatrization, reduced postoperative pain and swelling, can be combined with endoscopic, microscopic and robotic surgery. However, laser surgery has some major drawbacks: In contrast to conventional incisions with scalpels, the surgeon gets no feedback during laser ablation. There is no depth sensation and no tissue specificity with a laser incision, increasing the risk of iatrogenic damage to nerves and major blood vessels. Future prospects may solve these problems by means of an optical feedback mechanism that provides a tissue-specific laser ablation. First attempts have been made to perform remote optical tissue differentiation. Additionally, real time optical tumor detection during laser surgery would allow for a very precise and straight forward cancer resection, enhancing organ preservation and hence the quality of life for patients with cancer in the head and neck region.

    Full Text Available A systematic review of the literature concerning surgical engineering in cranio-maxillofacial surgery was performed. APubMed search yielded 1721 papers published between 1999 and 2011. Based on the inclusion/exclusion criteria, 1428 articles were excluded after review of titles and abstracts. Atotal of 292 articles were finally selected covering the following topics: finite element analysis (n = 18, computer-assisted surgery (n = 111, rapid prototyping models (n = 41, preoperative training simulators (n = 4, surgical guides (n = 23, image-guided navigation (n = 58, augmented reality (n = 2, video tracking (n = 1, distraction osteogenesis (n = 19, robotics (n = 8, and minimal invasive surgery (n = 7. The results show that surgical engineering plays a pivotal role in the development and improvement of cranio-maxillofacial surgery. Some technologies, such as computer-assisted surgery, image-guided navigation, and three-dimensional rapid prototyping models, have reached maturity and allow for multiple clinical applications, while augmented reality, robotics, and endoscopy still need to be improved.

    The ever-evolving medical field continues to trend toward less invasive approaches to the diagnosis and treatment of pathological conditions. Basic sciences research has allowed for improved technologies that are translated to the clinical sciences. Similarly, advancements in imaging modalities continue to improve and their applications become more varied. As such, surgeons and pathologists are able to depend on smaller samples for tissue diagnosis of pathological disease, where once large sections of tissue were needed. Optical coherence tomography (OCT), a high-resolution imaging technique, has been used extensively in different medical fields to improve diagnostic yield. Its use in dental fields, particularly in oral and maxillofacial surgery, remains limited. Our goal is to assess the use of OCT for improving soft tissue analysis and diagnosis, particularly for its applications in the field of oral and maxillofacial surgery. Optical coherence tomography is a modality that uses an optical signal using safe near-infrared light which is reflected off the sub-surface structures. This allows for high-resolution cross-sectional images of the tissue morphology to be obtained. Ophthalmologists have been using OCT to obtain images of the retina to assess for age-related macular degeneration. More recently, OCT has been used by Interventional Cardiology to image coronary arteries, and assess plaque thickness and morphology. This technology is now being investigated in several medical fields as a form of optical biopsy, providing in situ images with high-resolution morphology of tissues. We are particularly interested in its use on epithelial tissues, and therefore performed a literature review on the use of OCT for assessing epithelium. Evaluation of histologically-diagnosed actinic keratosis, for example, was found to correlate well with the imaging discrepancies found on OCT; and the in vivo assessment of atypical keratinocytes was firmly established.

    OBJECT Sport-related concussion (SRC) is a major public health problem. Approximately 90% of SRCs in high school athletes are transient; symptoms recover to baseline within 1 week. However, a small percentage of patients remain symptomatic several months after injury, with a condition known as postconcussion syndrome (PCS). The authors aimed to identify risk factors for PCS development in a cohort of exclusively young athletes (9-18 years of age) who sustained SRCs while playing a sport. METHODS The authors conducted a retrospective case-control study by using the Vanderbilt Sports Concussion Clinic database. They identified 40 patients with PCS and matched them by age at injury and sex to SRC control patients (1 PCS to 2 control). PCS patients were those experiencing persistent symptoms at 3 months after an SRC. Control patients were those with documented resolution of symptoms within 3 weeks of an SRC. Data were collected in 4 categories: 1) demographic variables; 2) key medical, psychiatric, and family history; 3) acute-phase postinjury symptoms (at 0-24 hours); and 4) subacute-phase postinjury features (at 0-3 weeks). The chi-square Fisher exact test was used to assess categorical variables, and the Mann-Whitney U-test was used to evaluate continuous variables. Forward stepwise regression models (Pin = 0.05, Pout = 0.10) were used to identify variables associated with PCS. RESULTS PCS patients were more likely than control patients to have a concussion history (p = 0.010), premorbid mood disorders (p = 0.002), other psychiatric illness (p = 0.039), or significant life stressors (p = 0.036). Other factors that increased the likelihood of PCS development were a family history of mood disorders, other psychiatric illness, and migraine. Development of PCS was not predicted by race, insurance status, body mass index, sport, helmet use, medication use, and type of symptom endorsement. A final logistic regression analysis of candidate variables showed PCS to be

    Full Text Available In day to day practice, the radiographic techniques used individually or in combination suffer from some inherent limits of all planar two-dimensional (2D projections such as magnification, distortion, superimposition, and misrepresentation of anatomic structures. The introduction of cone-beam computed tomography (CBCT, specifically dedicated to imaging the maxillofacial region, heralds a major shift from 2D to three-dimensional (3D approach. It provides a complete 3D view of the maxilla, mandible, teeth, and supporting structures with relatively high resolution allowing a more accurate diagnosis, treatment planning and monitoring, and analysis of outcomes than conventional 2D images, along with low radiation exposure to the patient. CBCT has opened up new vistas for the use of 3D imaging as a diagnostic and treatment planning tool in dentistry. This paper provides an overview of the imaging principles, underlying technology, dental applications, and in particular focuses on the emerging role of CBCT in dentistry.

    Fibrous dysplasia is believed to be a hamartomatous developmental lesion of unknown origin. This disease is divided into monostotic and polyostotic fibrous dysplasia. Polyostotic type can be divided into craniofacial type, Lichtenstein-Jaffe type, and McCune-Albright syndrome. In this case, a 31-year-old female presented spontaneous loss of right mandibular teeth before 5 years and has shown continuous expansion of right mandibular alveolus. Through the radiographic view, the coarse pattern of the mixed radiopaque-lucent lesion was seen on the right mandibular body, and there was diffuse pattern of the mixed radiopaque-lucent lesion with ill-defined margin in the left mandibular body. In the right calvarium, the lesion had cotton-wool appearance. Partial excision for contouring, multiple extraction, and alveoloplasty were accomplished under general anesthesia for supportive treatment. Finally we could conclude this case was polyostotic fibrous dysplasia of cranio-maxillofacial area based on the clinical, radiologic finding, and histopathologic examination.

    2013-04-01

    Botulinum toxin has a wide range of use in maxillo-facial surgery due to its action on muscles, on the glandular system, and against pain. It already has been given several market authorizations as indicated for: blepharospasm, spasmodic stiff neck, and glabellar lines. Furthermore, several studies are ongoing to prove its effectiveness and usefulness for many other pathologies: treatment of pain following cervical spine surgery; action on salivary glands after trauma, hypertrophy, or hyper-salivation; analgesic action (acknowledged but still being experimented) on neuralgia, articular pain, and keloids scars due to its anti-inflammatory properties. Botulinum toxin injections in the cervico-facial area are more and more used and should be to be correctly assessed. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available Maxillofacial prostheses is a dental medicine specialty aimed at restoring anatomical facial defects caused by cancer, trauma or congenital malformations through an artificial device, which is commonly attached to the skin with the help of an adhesive. The purpose of our research was to develop a pressure-sensitive adhesive (PSA based on acrylic monomers, characterizing and determining its drying kinetics, that is to say the time it takes to lose 50 to 90% of its moisture. The adhesive synthesis was realized by means of emulsion polymerization; the composition of formulations was: (AA‑MMA‑EA and (AA‑MMA‑2EHA with different molar ratios. The formulation based on (AA‑MMA‑2EHA with 50 w% of solids, presented good adhesive properties such as tack, bond strength, and short drying time. We propose this formulation as a PSA, because it offers an alternative for systemically compromised patients, by less irritation compared to organic solvent-based adhesives.

    Best, Al M; Laskin, Daniel M

    2013-01-01

    The purpose of this study was to evaluate residents' understanding of biostatistics and interpretation of research results. A questionnaire previously used in internal medicine residents was modified to include oral and maxillofacial surgery (OMS) examples. The survey included sections to identify demographic and educational characteristics of residents, attitudes and confidence, and the primary outcome-knowledge of biostatistics. In 2009 an invitation to the Internet survey was sent to all 106 program directors in the United States, who were requested to forward it to their residents. One hundred twelve residents responded. The percentage of residents who had taken a course in epidemiology was 53%; biostatistics, 49%; and evidence-based dentistry, 65%. Conversely, 10% of OMS residents had taken none of these classes. Across the 6-item test of knowledge of statistical methods, the mean percentage of correct answers was 38% (SD, 22%). Nearly half of the residents (42%) could not correctly identify continuous, ordinal, or nominal variables. Only 21% correctly identified a case-control study, but 79% correctly identified that the purpose of blinding was to reduce bias. Only 46% correctly interpreted a clinically unimportant and statistically nonsignificant result. None of the demographic or experience factors of OMS residents were related to statistical knowledge. Overall, OMS resident knowledge was below that of internal medicine residents (Pbiostatistics and the interpretation of research and are thus unprepared to interpret the results of published clinical research. Residency programs should include effective biostatistical training in their curricula to prepare residents in evidence-based dentistry.

    Byzantine physicians (4th-7th and 8th-12th centuries A.D.), especially those interested in Surgery, developed a number of interesting concepts, views and opinions referring to the field now recognized as Oral and Cranio-maxillofacial Surgery and Pathology. The original texts of Byzantine physicians, written in ancient Greek, and now preserved in the electronic platform Thesaurus Linguae Graecae, at the University of California, Irvine, CA, USA, were investigated in relation to Oral and Cranio-maxillofacial Surgery and Pathology. The most eminent physicians of the Early (4th-7th century A.D.) and Middle (8th-12th century A.D.) Byzantine Period, in particular Oribasius Pergamenus, Aëtius Amidenus, Alexander Trallianus, Theophilus Protospatharius, Paulus Aegineta, Meletius Monachos, and Leo Medicus, in their works deal with topographic and surgical anatomy of the head and neck, and a large list of related topics, including dentoalveolar surgery, oral and cervicofacial infections, trauma of viscerocranium and neurocranium as well as the biomechanics of traumatic brain injuries, temporomandibular joints dysfunction as a consequence of mandibular dislocation, surgical oncology and reconstructive surgery of the head and neck, oral pathology, surgical pathology of salivary glands, therapeutic management of facial nerve dysfunction, preprosthetic surgery, craniofacial surgery, and deformities of the facial skeleton involving anthropologic and craniometric observations. Clinical examination of patients presenting corresponding functional and esthetic problems is considered, using recognizable orthodontic and orthognathic surgical approaches. Finally, specific bandages of the head and neck are described, for treating traumatic injuries of the viscerocranium and neurocranium, diastasis of the cranial sutures, dislocations of the mandible (unilateral and bilateral), as well as inflammatory diseases of the parotids and the neck. Byzantine physicians had been particularly

    To analyze the release of metal into the adjacent tissues from stressed and nonstressed titanium and stainless steel miniplates and screws. Two miniplates were inserted into the cranial vaults of 12 beagle dogs while they were under general endotracheal anesthesia. One miniplate was shaped to fit the curvature of the skull (control). Another miniplate, made of the same material, was bent in a curve until the midpoint was raised 3 mm above the ends. Screws were inserted and tightened until the plate conformed to the skull curvature, creating stresses in the system. Four animals (2 each, having titanium or stainless steel plates and screws) were killed after 4, 12, and 24 weeks. Metallosis of adjacent soft tissues was assessed qualitatively. Miniplates and screws were removed, and adjacent soft tissue and bone was excised. Titanium, iron, chromium, nickel, and aluminum levels were assayed by ultraviolet/visible light and atomic absorption spectrophotometry. Nonparametric statistical methods were used for data analysis. There was no clear relationship between pigmentation of soft tissue adjacent to the miniplates and screws and the concentrations of metal present. The data did not demonstrate any consistent differences in the concentrations of metallic elements next to stressed and nonstressed (control) miniplates and screws of either material. Stresses arising through poor contouring of miniplates do not appear to influence the extent of release of metal into the adjacent tissues.

    Full Text Available Trauma management has evolved significantly in the past few decades thereby reducing mortality in the golden hour. However, challenges remain, and one such area is maxillofacial injuries in a polytrauma patient. Severe injuries to the maxillofacial region can complicate the early management of a trauma patient owing to the regions proximity to the brain, cervical spine, and airway. The usual techniques of airway breathing and circulation (ABC management are often modified or supplemented with other methods in case of maxillofacial injuries. Such modifications have their own challenges and pitfalls in an already difficult situation.

    Efficient responses to emergencies in the oral and maxillofacial surgery office require preparation, communication, and thorough documentation of the event and response. The concept of team anesthesia is showcased with these efforts. Emergency medical services training and response times vary greatly. The oral and maxillofacial surgery office should be prepared to manage the patient for at least 15 minutes after making the call to 911. Patient outcomes are optimized when providers work together to manage and transport the patient. Oral and maxillofacial surgery offices should develop and rehearse emergency plans and coordinate these protocols with local Emergency medical services teams. Copyright © 2018 Elsevier Inc.

    This paper provides an overview of the epidemiology of sport-related concussion and associated costs in New Zealand requiring medical treatment from 2001 to 2011 in seven sports codes. A retrospective review of injury entitlement claims by seven sports from 2001 to 2011. Data were analyzed by sporting code, age, ethnicity, gender and year of competition for total and moderate-to-severe (MSC) Accident Compensation Corporation (ACC) claims and costs. A total of 20,902 claims costing $NZD 16,546,026 were recorded over the study period of which 1330 (6.4%) were MSC claims. The mean yearly number and costs of MSC claims were 133 ± 36 and $1,303,942 ± 378,949. Rugby union had the highest number of MSC claims per year (38; 95% CI 36-41 per 1000 MSC claims). New Zealand Māori recorded the highest total ($6,000,759) and mean cost ($21,120) per MSC claim. Although MSC injury claims were only 6.4% of total claims, they accounted for 79.1% of total costs indicating that although the majority of sport-related concussions may be minor in severity, the related economic costs associated with more serious sport-related concussion can be high. The finding that rugby union recorded the most MSC claims in the current study was not unexpected. Of concern is that rugby league recorded a low number of MSC claims but the highest mean cost per claim. Due to the high mean cost per concussion, and the high total and mean cost for New Zealand Māori, further investigation is warranted. Copyright © 2013 Sports Medicine Australia.

    Maxillofacial fractures are encountered less commonly during childhood period due to anatomic, social, cultural, and environmental factors. Although the incidence of all maxillofacial fractures is 1% to 15% among pediatric and adolescent patients, this rate drops to less than 1% in children below 5 years age. Two hundred thirty-five cases (mandibular fracture were evaluated retrospectively. Patients records were examined in terms of age, gender, cause of fracture, fracture localization, number of fractures, fracture pattern, accompanying injuries, applied treatment methods, and complications. Mean age of cases was 9.2 years and 165 cases were male, 70 were female. Traffic accidents as the most common etiologic cause in all ages. Falls is the second most common cause which particularly affects children above age of 2 years. All cases had 333 fractures and the most common fracture localization was parasymphysis region (34%). The other most common fracture localizations were as follows: condyle (19%), corpus (13%), dentoalveolar region (12%), angulus (11%), symphysis region (9%), and ramus (2%). There was only a single fracture line in 145 cases, 40 cases had unilateral multiple and 50 cases had bilateral fracture lines. We applied symptomatic (conservative) treatment in 20 (8%) of our cases; fracture fixation with interdental wires or closed reduction methods were employed in 122 patients. Internal fixation with open reduction (OR) was performed on 51 (22%) patients. Both closed and OR techniques were carried out in 30 (13%) patients. Pediatric mandibular fractures, which are seen less frequently compared with those of adults, require a specific and different treatment. Although mostly less invasive methods are preferred, we believe that ORs should be considered when required.

    The surgical treatment of mandibular condylar fractures is commonly performed. We had for aim to present the latest trends in the surgical management of condylar fractures in France, between 2005 and 2012. A survey was performed among the 49 members of the French college of oral and maxillofacial surgeons between January and September 2012, with a questionnaire sent by email. We analyzed the therapeutic management, the surgical indications; the techniques used according to the fracture, and the postoperative treatment protocols. The data was compared to that of a similar study performed in 2005. The overall reply rate was 86%. Low subcondylar fractures were operated on in all institutions (100%), compared to 76% in 2005. The most popular technique was the high submandibular approach with intraoral miniplate fixation osteosynthesis. High subcondylar and diacapitular fractures were operated on in respectively 82% and 35% of the cases compared to 29% and 10% in 2005 with various surgical techniques and postoperative management. French maxillofacial surgeons operated on more mandibular condylar fractures in 2012 than in 2005. As observed in 2005, the lower and the more dislocated the fractures were, the more they were operated on. The high submandibular approach has become the most popular approach. The use of miniplates for bone fixation has become common. Diacapitular fractures were usually treated functionally. The postoperative management varied greatly from one team to the other.

    Recently, there has been a trend towards the search for new, safe and effective methods of reconstruction of maxillofacial defects after tumor excision. Among various materials used for bone defect reconstruction, ceramics has attached a great deal of attention. The purpose of our study was to develop a technique for personified approach to the reconstruction of maxillofacial bone defects with bioactive ceramic implants. In our study we used the technique of virtual implant planning for maxillofacial reconstruction using preoperative CT data of the patient's facial skeleton. Bioactive ceramic implant materials meet all the requirements for medical materials used in reconstructive surgery. The technique described in this paper to customize prefabricated bioactive ceramic implants enables surgeons to perform reconstruction of large postoperative defects in the maxillofacial region, thereby making custom implants suitable for any patient. The use of this technique decreases surgical time, reduces time needed for postoperative recovery, lowers overall patient morbidity and optimizes aesthetic and functional results.

    Nicholoff, T J; Del Castillo, C B; Velmonte, M X

    Maxillofacial injuries resulting from trauma can be a challenge to the Maxillo-Facial Surgeon. Frequent causes of these injuries are attributed to automobile accidents, physical altercations, gunshot wounds, home accidents, athletic injuries, work injuries and other injuries. Motor vehicle accidents tend to be the primary cause of most midface fractures and lacerations due to the face hitting the dashboard, windshield and steering wheel or the back of the front seat for passengers in the rear. Seatbelts have been shown to drastically reduce the incidence and severity of these injuries. In the United States seatbelt laws have been enacted in several states thus markedly impacting on the reduction of such trauma. In the Philippines rare is the individual who wears seat belts. Metro city traffic, however, has played a major role in reducing daytime MVA related trauma, as usually there is insufficient speed in traffic areas to cause severe impact damage, the same however cannot be said for night driving, or for driving outside of the city proper where it is not uncommon for drivers to zip into the lane of on-coming traffic in order to overtake the car in front ... often at high speeds. Thus, the potential for severe maxillofacial injuries and other trauma related injuries increases in these circumstances. It is however unfortunate that outside of Metro Manila or other major cities there is no ready access to trauma or tertiary care centers, thus these injuries can be catastrophic if not addressed adequately. With the exception of Le Fort II and III craniofacial fractures, most maxillofacial injuries are not life threatening by themselves, and therefore treatment can be delayed until more serious cerebral or visceral, potentially life threatening injuries are addressed first. Our patient was involved in an MVA in Zambales, seen and stabilized in a provincial primary care center initially, then referred to a provincial secondary care center for further stabilization

    Full Text Available History of present illness: A 77-year-old female presented to her primary care physician (PCP with right hip pain after a mechanical fall. She did not lose consciousness or have any other traumatic injuries. She was unable to ambulate post-fall, so X-rays were ordered by her PCP. Her X-rays were concerning for a right acetabular fracture (see purple arrows, so the patient was referred to the emergency department where a computed tomography (CT scan was ordered. Significant findings: The non-contrast CT images show a minimally displaced comminuted fracture of the right acetabulum involving the acetabular roof, medial and anterior walls (red arrows, with associated obturator muscle hematoma (blue oval. Discussion: Acetabular fractures are quite rare. There are 37 pelvic fractures per 100,000 people in the United States annually, and only 10% of these involve the acetabulum. They occur more frequently in the elderly totaling an estimated 4,000 per year. High-energy trauma is the primary cause of acetabular fractures in younger individuals and these fractures are commonly associated with other fractures and pelvic ring disruptions. Fractures secondary to moderate or minimal trauma are increasingly of concern in patients of advanced age.1 Classification of acetabular fractures can be challenging. However, the approach can be simplified by remembering the three basic types of acetabular fractures (column, transverse, and wall and their corresponding radiologic views. First, column fractures should be evaluated with coronally oriented CT images. This type of fracture demonstrates a coronal fracture line running caudad to craniad, essentially breaking the acetabulum into two halves: a front half and a back half. Secondly, transverse fractures should be evaluated by sagittally oriented CT images. By definition, a transverse fracture separates the acetabulum into superior and inferior halves with the fracture line extending from anterior to posterior

    3D printing seems to have more and more applications in maxillofacial surgery (MFS), particularly since the release on the market of general use 3D printers several years ago. The aim of our study was to answer 4 questions: 1. Who uses 3D printing in MFS and is it routine or not? 2. What are the main clinical indications for 3D printing in MFS and what are the kinds of objects that are used? 3. Are these objects printed by an official medical device (MD) manufacturer or made directly within the department or the lab? 4. What are the advantages and drawbacks? Two bibliographic researches were conducted on January the 1st, 2017 in PubMed, without time limitation, using "maxillofacial surgery" AND "3D printing" for the first and for the second "maxillofacial surgery" AND "computer-aided design" AND "computer-aided manufacturing" as keywords. Articles in English or French dealing with human clinical use of 3D printing were selected. Publication date, nationality of the authors, number of patients treated, clinical indication(s), type of printed object(s), type of printing (lab/hospital-made or professional/industry) and advantages/drawbacks were recorded. Two hundred and ninety-seven articles from 35 countries met the criteria. The most represented country was the People's Republic of China (16% of the articles). A total of 2889 patients (10 per article on average) benefited from 3D printed objects. The most frequent clinical indications were dental implant surgery and mandibular reconstruction. The most frequently printed objects were surgical guides and anatomic models. Forty-five percent of the prints were professional. The main advantages were improvement in precision and reduction of surgical time. The main disadvantages were the cost of the objects and the manufacturing period when printed by the industry. The arrival on the market of low-cost printers has increased the use of 3D printing in MFS. Anatomic models are not considered to be MDs and do not have

    Full Text Available According to the Advanced Trauma Life Support recommendations for managing patients with life-threatening injuries, securing the airway is the first task of a primary caregiver. Airway management of patients with maxillofacial trauma is complex and crucial because it can dictate a patient’s survival. Securing the airway of patients with maxillofacial trauma is often extremely difficult because the trauma involves the patient’s airway and their breathing is compromised. In these patients, mask ventilation and endotracheal intubation are anticipated to be difficult. Additionally, some of these patients may not yet have been cleared of a cervical spine injury, and all are regarded as having a full stomach and having an increased risk of regurgitation and pulmonary aspiration. The requirements of the intended maxillofacial operation may often preclude the use of an oral intubation tube, and alternative methods for securing the airway should be considered before the start of the surgery. In order to improve the clinical outcome of patients with maxillofacial trauma, cooperation between maxillofacial surgeons, anesthesiologists, and trauma specialists is needed. In this review, we discuss the complexity and difficulties of securing the airway of patients with maxillofacial trauma and present our approach for airway management of such patients.

    Full Text Available Background and Objective: The incidence of maxillofacial trauma is increasing at a very fast pace in developing countries like India and poses a major health burden. Hence, the epidemiological data of maxillofacial trauma during a 6 year period, was analyzed to study the characteristics, factors predisposing, and aid in advocating strict guidelines to prevent the same. Materials and Methods: Data related to 638 cases with maxillofacial trauma, from January 2008 to December 2014 were reviewed retrospectively and the data regarding gender, age, etiology, anatomic location of fracture, alcohol consumption, associated head and other injuries, modality of treatment rendered and associated complications were analyzed with descriptive statistics. Results: A total of 638 patients presenting with 869 maxillofacial fractures were analyzed. Most of them [344 (53.9%] were young adults aged 18-40, whereas, 123 (19.2% were 11 to 17 years, and 97(15.2% adults. Men (79.4% were more affected than women. Road traffic accidents remain the main etiology causing fractures in 470 (73.6%, whereas 397 (62.2% had history of consumption of alcohol. Those with alcohol intoxication had multiple injuries. Mandible was more frequently involved with 360 (41.4% fractures, and condyle being the most common site. A total of 374 (58.6% underwent open reduction with internal fixation under general anesthesia. Prevalence of other injuries was noted in 207 (32.4% and complications of fracture treatment in 41(6.4% cases. Conclusion: Road traffic accidents under alcohol influence were most commonly associated with comminuted facial fractures with head injuries, frequently leading to death. Mandible was the most commonly fractured facial bone followed by zygoma

    This study was performed to evaluate the reliability of the identification of anatomical landmarks in panoramic and lateral cephalometric radiographs on a standard medical grade picture archiving communication system (PACS) monitor and a tablet computer (iPad 5). A total of 1000 radiographs, including 500 panoramic and 500 lateral cephalometric radiographs, were retrieved from the de-identified dataset of the archive of the Section of Oral and Maxillofacial Radiology of the University Of Connecticut School Of Dental Medicine. Major radiographic anatomical landmarks were independently reviewed by two examiners on both displays. The examiners initially reviewed ten panoramic and ten lateral cephalometric radiographs using each imaging system, in order to verify interoperator agreement in landmark identification. The images were scored on a four-point scale reflecting the diagnostic image quality and exposure level of the images. Statistical analysis showed no significant difference between the two displays regarding the visibility and clarity of the landmarks in either the panoramic or cephalometric radiographs. Tablet computers can reliably show anatomical landmarks in panoramic and lateral cephalometric radiographs.

    The purpose of this study was to obtain the cephalometric maxillofacial soft tissue measurements and to define the differences that exist between male and female on the soft tissue profile who had normal occlusion in mixed dentitions. For the object of this study, cephalometric radiographs were obtained from the centric occlusion with the relaxed lip position. Copper filter was designed to obtain both hard and soft tissue structure on the same film. The subjects consist of 100 male and 100 female from 8 to 12.4 years with the normal occlusion and acceptable profiles. The author measured facial depth, vertical height from the cephalometric soft tissue profiles in the mixed dentitions. The significant test was performed to compare male with females. The following results were obtained from the study 1. In facial convexity, much more larger female than that of male. 2. Inclination of the lip posture was more larger in maxilla (male) and in female more larger in the mandible. 3. The thickness of soft tissue was thicker in male, the height of nose was more prominent in female. 4. There were no significant differences in both sexes.

    The aim of this study was to determine the circumstances of aggressions and patterns of maxillofacial injuries among victims of interpersonal violence. This was a cross-sectional and exploratory study conducted from the analysis of 7,132 medical-legal and social records of interpersonal violence victims seen in a Forensic Medicine and Dentistry Center. Descriptive and multivariate statistics were performed using Multiple Correspondence Analysis. Three groups with different victimization profiles were identified. The first group was mainly composed of men of different age groups, victims of community violence that resulted in facial bones or dentoalveolar fracture. The second group was mainly composed of adolescents (10-19 years) of both sexes, victims of interpersonal violence and without specific pattern of injuries. The third group was composed of adult women (≥ 20 years) victims of domestic violence that resulted in injuries of soft tissues of face or other body regions. The results suggest that sociodemographic and circumstantial characteristics are important factors in victimization by maxillofacial injuries and interpersonal violence.

    Aim . This study aims to explain the main steps that characterize the implant-prosthetic rehabilitation in complex combined dental and maxillofacial trauma. Material and Methods . A 20-year-old patient reported an extensive facial trauma which also involved the alveolar process of the maxillary bone. The patient reported a maxillofacial fracture and the loss of teeth 1.3, 1.2, 1.1, and 2.1. A "Le Fort" type 2 fracture was also reported, with the malar bone involvement. After reduction and containment of bone fractures, through appropriate mounting plates, appropriate functional and aesthetic rehabilitation of the patient were replaced thanks to a temporary removable prosthesis. After 6 months, the patient performed numerous clinical investigations, aimed at a proper planning of implant-prosthetic rehabilitation of the upper dental arch. Conclusion . With the planning of the case, as well as respecting the surrounding biological structures, the surgery of implants can be carried out with the most appropriate procedure. Lastly, new dental implants with highly bioactive surfaces have been developed, providing an excellent and rapid bone integration.

    Internal bone fixation devices made with permanent metals are associated with numerous long-term complications and may require removal. We hypothesized that fixation devices made with degradable magnesium alloys could provide an ideal combination of strength and degradation, facilitating fracture fixation and healing while eliminating the need for implant removal surgery. Fixation plates and screws were machined from 99.9% pure magnesium and compared with titanium devices in a rabbit ulnar fracture model. Magnesium device degradation and the effect on fracture healing and bone formation were assessed after 4 weeks. Fracture healing with magnesium device fixation was compared with that of titanium devices using qualitative histologic analysis and quantitative histomorphometry. Micro-computed tomography showed device degradation after 4 weeks in vivo. In addition, 2-dimensional micro-computed tomography slices and histologic staining showed that magnesium degradation did not inhibit fracture healing or bone formation. Histomorphology showed no difference in bone-bridging fractures fixed with magnesium and titanium devices. Interestingly, abundant new bone was formed around magnesium devices, suggesting a connection between magnesium degradation and bone formation. Our results show potential for magnesium fixation devices in a loaded fracture environment. Furthermore, these results suggest that magnesium fixation devices may enhance fracture healing by encouraging localized new bone formation.

    The aim of this study is to retrospectively analyze the incidence of facial fractures along with age, gender predilection, etiology, commonest site, associated dental injuries, and any complications of patients operated in Craniofacial Unit of SDM College of Dental Sciences and Hospital. This retrospective study was conducted at the Department of OMFS, SDM College of Dental Sciences, Dharwad from January 2003 to December 2013. Data were recorded for the cause of injury, age and gender distribution, frequency and type of injury, localization and frequency of soft tissue injuries, dentoalveolar trauma, facial bone fractures, complications, concomitant injuries, and different treatment protocols.All the data were analyzed using statistical analysis that is chi-squared test. A total of 1146 patients reported at our unit with facial fractures during these 10 years. Males accounted for a higher frequency of facial fractures (88.8%). Mandible was the commonest bone to be fractured among all the facial bones (71.2%). Maxillary central incisors were the most common teeth to be injured (33.8%) and avulsion was the most common type of injury (44.6%). Commonest postoperative complication was plate infection (11%) leading to plate removal. Other injuries associated with facial fractures were rib fractures, head injuries, upper and lower limb fractures, etc., among these rib fractures were seen most frequently (21.6%). This study was performed to compare the different etiologic factors leading to diverse facial fracture patterns. By statistical analysis of this record the authors come to know about the relationship of facial fractures with gender, age, associated comorbidities, etc.

    Full Text Available Abstract Objective To compare periapical radiograph (PR and cone-beam computed tomography (CBCT in the diagnosis of alveolar and root fractures. Material and Methods Sixty incisor teeth (20 higid and 40 with root fracture from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 with alveolar fracture of 15 macerated canine maxillae. Each fractured socket had a root fractured tooth inserted in it. Afterwards, each maxilla was submitted to PR in two different vertical angulation incidences, and to CBCT imaging with a small field of view (FOV and high-definition protocol. Images were randomized and posteriorly analyzed by two oral and maxillofacial radiologists two times, with a two-week interval between observations. Results Sensitivity and specificity values were good for root fractures for PR and CBCT. For alveolar fractures, sensitivity ranged from 0.10 to 0.90 for PR and from 0.50 to 0.65 for CBCT. Specificity for alveolar fractures showed lower results than for root fractures for PR and CBCT. Areas under the ROC curve showed good results for both PR and CBCT for root fractures. However, results were fair for both PR and CBCT for alveolar fractures. When submitted to repeated measures ANOVA tests, there was a statistically significant difference between PR and CBCT for root fractures. Root fracture intraobserver agreement ranged from 0.90 to 0.93, and alveolar fracture intraobserver agreement ranged from 0.30 to 0.57. Interobserver agreement results were substantial for root fractures and poor/fair for alveolar fractures (0.11 for PR and 0.30 for CBCT. Conclusion Periapical radiograph with two different vertical angulations may be considered an accurate method to detect root fractures. However, PR showed poorer results than CBCT for the diagnosis of alveolar fractures. When no fractures are diagnosed in PR and the patient describes pain symptoms, the subsequent exam of choice is CBCT.

    The increasing popularity of participating in sports activities among children and adolescents has increased the risk of sports-related orofacial and dental injuries. Therefore, it is important to establish efficient preventive strategies regarding sports-related dental trauma. The aim of this study was to evaluate the occurrence of sports-related dental injuries in young athletes and to compare the frequency of such injuries between high-risk and medium-risk sports, along with assessing athletes' attitudes and habits regarding mouthguard use. A total of 229 young athletes from four different sports (water polo (n = 59), karate (n = 58), taekwondo (n = 57) and handball (n = 55)) participated in this study. A standardized questionnaire about the frequency of orofacial and dental injuries was used. Questions were also asked about athletes' habits related to mouthguard use. Mean age of the participants was 12.9 ± 3.2 years, and the average time of playing experience was 4.8 ± 3.1 years. Orofacial injury had been experienced by 58 athletes (25.3%), while 31 athletes (13.5%) suffered dental injury. Higher rate of dental injuries was observed in water polo (18.6%), karate (17.2%) and handball (21.8%) than in taekwondo (3.5%) (P = .035). Most participants were aware of mouthguards for dental trauma prevention and considered them efficient for preventing dental injuries during sports activities, but only 94 (41%) used them. There was a statistically significant difference in the use of mouthguards between taekwondo (73.7%) and karate (70.7%) players compared to handball (14.5%) and water polo players (5.1%) (P art sport. Therefore, the classification of sports according to the risk of dental trauma should be reconsidered. It would be beneficial to make wearing a mouthguard mandatory in all high-risk sports, as well as in those with medium-risk for dental injuries. © 2018 John Wiley & Sons A/S.

    To analyze the incidence and severity of maxillofacial injuries in the Second Lebanon War, that occurred during the summer of 2006, among Israeli soldiers and civilians. This is a retrospective cohort study of patients recorded in the Israel National Trauma Registry during the Second Lebanon War. Data refer to all general hospitals throughout the country. Data were analyzed according to the etiology of the injury, severity of trauma using the Injury Severity Score, trauma location, and duration of hospital stay. Cases with multiple injuries that included maxillofacial injuries were separated and further analyzed according to the above parameters. Patients with only dental injuries and superficial facial soft tissue lacerations were excluded because they were referred to the military dental clinics and not to general hospitals. Maxillofacial injuries were found in 36 (6.4%) of the 565 wounded. Patients with maxillofacial injuries ranged in age from 20 to 44 years (mean age, 25.5 +/- 5.7 years). Greater than 50% of the injuries required more than 3 hospitalization days. Mortality rate of the maxillofacial injured was 2.8%. Most of the maxillofacial injuries (33; 91.7%) were combined with other organ injuries; 9 (25%) patients also had dental injuries. In the Second Lebanon War, the incidence and severity of true maxillofacial injuries, without dental injuries alone, were relatively low compared with previous reports of other conflicts. However, because most injuries involved multiple organs, special attention is required when planning and providing emergency, as well as secondary and tertiary medical care to war wounded.

    This study analyses the different parts of the upper airway space and the changes in hyoid position. The results provide a clinical reference for developing timely and effective treatment programmes for patients with mandibular fractures caused by maxillofacial trauma. Standard X-cephalometric measurements of the lateral skull of 210 subjects were taken. The subjects were divided into four fracture groups: condylar, mandibular angle, mandibular body, and parasymphyseal. The radiographs of the mandibular fracture groups were compared with the normal occlusion group to analyse the upper airway space and the changes in hyoid position. Different types of fractures have different effects on the upper airway space. Bilateral mandibular body fracture and the parasymphyseal fracture have a significant influence on the lower oropharyngeal and laryngopharyngeal airway spaces, with serious obstructions severely restricting the ventilatory function of patients. Fractures at different parts of the mandibular structure are closely related to the upper airway and hyoid position.

    With the advent of CAD/CAM and rapid prototyping (RP), a technical revolution in oral and maxillofacial trauma was promoted to benefit treatment, repair of maxillofacial fractures and reconstruction of maxillofacial defects. For a patient with zygomatico-facial collapse deformity resulting from a zygomatico-orbito-maxillary complex (ZOMC) fracture, CT scan data were processed by using Mimics 10.0 for three-dimensional (3D) reconstruction. The reduction design was aided by 3D virtual imaging and the 3D skull model was reproduced using the RP technique. In line with the design by Mimics, presurgery was performed on the 3D skull model and the semi-coronal incision was taken for reduction of ZOMC fracture, based on the outcome from the presurgery. Postoperative CT and images revealed significantly modified zygomatic collapse and zygomatic arch rise and well-modified facial symmetry. The CAD/CAM and RP technique is a relatively useful tool that can assist surgeons with reconstruction of the maxillofacial skeleton, especially in repairs of ZOMC fracture.

    Badminton players of varying skill levels viewed normal and point-light video clips of opponents striking the shuttle towards the viewer; their task was to predict in which quadrant of the court the shuttle would land. In a whole-brain fMRI analysis we identified bilateral cortical networks sensitive to the anticipation task relative to control stimuli. This network is more extensive and localised than previously reported. Voxel clusters responding more strongly in experts than novices were associated with all task-sensitive areas, whereas voxels responding more strongly in novices were found outside these areas. Task-sensitive areas for normal and point-light video were very similar, whereas early visual areas responded differentially, indicating the primacy of kinematic information for sport-related anticipation.

    Sports-related concussion among professional, collegiate, and, more recently, high school athletes has received much attention from the media and medical community. To our knowledge, there is a paucity of research regarding parental knowledge of sports-related concussion. The aim of this study was to evaluate parental knowledge of concussion in young children who participated in recreational tackle football. Parents of children aged 5 years to 15 years attending recreational tackle football games were asked to complete an anonymous questionnaire based on the Centers for Disease Control and Prevention's Heads Up: Concussion in Youth Sports Quiz. The parents were asked about their level of agreement regarding statements that represent definition, symptoms, and treatment of concussion. A total of 310 of 369 parents (84% response rate) voluntarily completed the questionnaire, with 94% believing that their child had never had a concussion. However, only 13% (n = 41) could correctly identify all seven statements. Most did not identify that a concussion is considered a mild traumatic brain injury and can be achieved from something other than a direct blow to the head. Race, sex, and zip code had no significant association with correctly answering statements. Education (r = 0.24, p child played (r = 0.11, p = 0.049) had a small association. Fifty-three percent and 58% of the parents reported that someone had discussed the definition and the symptoms of concussion with them, respectively, with only about half reporting that information came from their health care provider. No parent was able to classify all symptoms listed as correctly related or not related to concussion. However, identification of correct concussion statements correlated with identification of correct symptoms (r = 0.25, p < 0.001). While most parents of young athletes demonstrated some knowledge regarding concussion, important misconceptions remain regarding the definition, symptoms, and treatment of

    The aim of this study was to evaluate the clinical outcome of patients with mandibular angle fractures treated by intraoral access and a rectangular grid miniplate with 4 holes and stabilized with monocortical screws. This study included 45 patients with mandibular angle fractures from the Department of Oral and Maxillofacial Surgery São Paulo State University, Araraquara, Brazil, and from the Clinic of Oral and Maxillofacial Surgery at the University of Frankfurt, Germany. The 45 fractures of the mandibular angle were treated with a rectangular grid miniplate of a 2.0-mm system by an intraoral approach with monocortical screws. Clinical evaluations were postoperatively performed at 15 and 30 days and 3 and 6 months, and the complications encountered were recorded and treated. The infection rate was 4.44% (2 patients), and in 1 patient it was necessary to replace hardware. This patient also had a fracture of the left mandibular body; 3 patients (6.66%) had minor occlusal changes that have been resolved with small occlusal adjustments. Before surgery, 15 patients (33.33%) presented with hypoesthesia of the inferior alveolar nerve; 4 (8.88%) had this change until the last clinical control, at 6 months. The rectangular grid miniplate used in this study was stable for the treatment of simple mandibular angle fractures through intraoral access, with low complication rates, easy handling, and easy adjustment, with a low cost. Concomitant mandibular fracture may increase the rate of complications. This plate should be indicated in fractures with sufficient interfragmentary contact.

    Full Text Available Background: The choice of reconstruction options for maxillectomy defects varies significantly. Factors affecting it range from the type of defect to the surgeon's expertise. This study aims to evaluate the practice of Nigerian Oral and Maxillofacial surgeons in the reconstruction of post-maxillectomy defects. Materials and Methods: The survey was conducted by use of questionnaires administered at the annual scientific meeting of the oral and maxillofacial surgeons of Nigeria in Ibadan 2012. Results: A response rate of 66.7% was achieved. All of our respondents are consultant oral and maxillofacial surgeons, 80% of whom practice in a teaching hospital. All but one of them perform maxillectomies, however only 25% of them offer surgical reconstruction of the resulting defects to patients. Flaps have been used by 25% of the respondents, while none of them has employed microvascular reconstruction. Prosthetic rehabilitation of patients is pervasive among the respondents. Conclusion: Maxillectomy defects have far-reaching consequences on patients' quality of life and attempts should be made to reconstruct such defects. Although maxillectomy is a commonly performed procedure among oral and maxillofacial surgeons in Nigeria, especially for malignancies of the oral and paranasal sinuses, surgical reconstruction of resulting defects is not so frequently done. Microvascular surgery, which is becoming a frequently utilized option among surgeons in developed nations, is still infrequently used in our environment. There is a need for oral and maxillofacial surgeons in our climes to improve their skills so as to increase the range of reconstructive options offered.

    Publication bias (PB) diminishes the full distribution of research, distorts and discredits the scientific record, and thus compromises evidence-based practice. The objective of this study was to analyse published controlled trials with regard to PB in leading oral and maxillofacial surgery (OMS) journals. All controlled trials published in the International Journal of Oral and Maxillofacial Surgery, Journal of Cranio-Maxillofacial Surgery, Journal of Oral and Maxillofacial Surgery, and British Journal of Oral and Maxillofacial Surgery in 2008 were analysed for a primary outcome, country of authors, sample size, gender of the first author, funding source and location of the study. Of 952 published articles, 53 controlled trials (5.7%) were identified. The OMS journals preferentially published controlled trials with a positive outcome (77.4%) and from high-income countries (73.6%). Single-centred trials (86.8%) with low sample size (njournals should establish measures to eliminate PB to uphold scientific integrity. However, this study was an observation based on the published articles. An analysis of all submitted manuscripts would provide more accurate estimates of PB. Ethical considerations on PB are also discussed.

    This retrospective observational study investigated the frequency of reporting ethical approval and informed consent in recently published oral and maxillofacial surgery (OMS) research involving human subjects. All research involving human subjects published in the International Journal of Oral and Maxillofacial Surgery, Journal of Oral and Maxillofacial Surgery, British Journal of Oral and Maxillofacial Surgery, and Journal of Cranio-Maxillofacial Surgery during January to June 2005-2007 were analysed for disclosure of ethical approval by a local ethical committee and obtaining informed consent from the subjects. 534 articles were identified; ethical approval was documented in 118 (22%) and individual patient consent in 135 (25%). 355 reports (67%) did not include a statement on ethical approval or informed consent and only 74 reports (14%) disclosed statements of both. Ethical documentation in retrospective and observational studies was scant; 12% of randomised controlled trials and 38% of non-random trials did not report both of ethical protections. Most recent OMS publications involving humans failed to mention ethical review or subjects' consent. Authors must adhere to the international research ethics guidelines and journal instructions, while editors should play a gatekeeper role to protect research participants, uphold scientific integrity and maintain public trust in the experimental process and OMS profession.

    Computer-assisted surgical (CAS) planning tools have become widely available in craniomaxillofacial surgery, but are time consuming and often require professional technical assistance to simulate a case. An initial oral and maxillofacial (OM) surgical user experience was evaluated with a newly developed CAS system featuring a bimanual sense of touch (haptic). Three volunteer OM surgeons received a 5-minute verbal introduction to the use of a newly developed haptic-enabled planning system. The surgeons were instructed to simulate mandibular fracture reductions of 3 clinical cases, within a 15-minute time limit and without a time limit, and complete a questionnaire to assess their subjective experience with the system. Standard landmarks and linear and angular measurements between the simulated results and the actual surgical outcome were compared. After the 5-minute instruction, all 3 surgeons were able to use the system independently. The analysis of standardized anatomic measurements showed that the simulation results within a 15-minute time limit were not significantly different from those without a time limit. Mean differences between measurements of surgical and simulated fracture reductions were within current resolution limitations in collision detection, segmentation of computed tomographic scans, and haptic devices. All 3 surgeons reported that the system was easy to learn and use and that they would be comfortable integrating it into their daily clinical practice for trauma cases. A CAS system with a haptic interface that capitalizes on touch and force feedback experience similar to operative procedures is fast and easy for OM surgeons to learn and use.

    Maxillofacial injuries are most commonly associated with falls, motor and vehicle accidents, sports-related trauma, and interpersonel violence. The complexity of mandibular condyle region and its anatomic proximity to other craniofacial structures complicate diagnosis and treatment. Thus, treatment approaches of mandibular condyle fracture are still controversial. In the literature, different success rates are reported about observation versus treatment, closed reduction versus open reduction...

    To describe the application of 3-dimensional (3D) printing in advanced oral and maxillofacial surgery (OMFS) and to discuss the benefits of this modality in surgical planning, student and resident training, and client education. Retrospective case series. Client-owned dogs (n = 28) and cats (n = 4) with 3D printing models of the skulls. The medical records of 32 cases with 3D printing prior to major OMFS were reviewed. Indications for 3D printing included preoperative planning for mandibular reconstruction after mandibulectomy (n = 12 dogs) or defect nonunion fracture (n = 6 dogs, 2 cats), mapping of ostectomy location for temporomandibular joint ankylosis or pseudoankylosis (n = 4 dogs), assessment of palatal defects (n = 2 dogs, 1 cat), improved understanding of complex anatomy in cases of neoplasia located in challenging locations (n = 2 dogs, 1 cat), and in cases of altered anatomy secondary to trauma (n = 2 dogs). In the authors' experience, 3D printed models serve as excellent tools for OMFS planning and resident training. Furthermore, 3D printed models are a valuable resource to improve clients' understanding of the pet's disorder and the recommended treatment. Three-dimensional printed models should be considered viable tools for surgical planning, resident training, and client education in candidates for complex OMFS. © 2017 The American College of Veterinary Surgeons.

    Full Text Available BACKGROUND Mandible fractures are a frequent injury because of the mandible's prominence and relative lack of support. The purpose of this study is to clinically determine the most common sites and the prevalence of isolated fracture mandible in our scenario and determine most common traumatic aetiology factor responsible for fracture mandible. Numerous investigators have reported studies on populations on all continents; fractures of the mandible have been reported to account for 36-70% of all maxillofacial fractures. All reports apparently show a higher frequency in males aged 21-30 yrs. There is an emerging trend towards an increase in the frequency of violent mechanisms of fracture and in the proportion of adolescents and young adults sustaining such injuries. MATERIALS AND METHODS Patients treated at the Otorhinolaryngology Head and Neck Surgery Department of B.D.B.A. Hospital from a period between January 2014 to January2016 were (retrospectively evaluated with respect to age groups, gender, aetiology, localisation, type of fractures and treatment. RESULTS Total number of patients 38, 2 patients had bilateral fracture, males 27 (71.05%, females 11 (28.95%. Anatomical location symphysis and parasymphysis 14 (35%, condylar 12 (30%, body 7 (17.5%, angle 6 (15%, coronoid 1 (2.5%. Aetiological factors road traffic accidents 19 (50%, assault 13 (34.24%, fall 3 (7.89%, work-related trauma 2 (5.26%, sports trauma 1 (2.6%. CONCLUSION This study indicates that most common fracture in adult patient were symphysis and parasymphysis, second most common were condylar followed by body fracture and angle fracture. The most common cause of the injury maybe road traffic accidents, second most common assault followed by work related injuries, fall and sports injuries.

    Fractures are not only the weak planes of a rock mass, but also the easy passages for the fluid flow. Their spacing, orientation, and aperture will affect the deformability, strength, heat transmittal, and fluid transporting properties of the rock mass. To understand the thermomechanical and hydrological behaviors of the rock surrounding the heater emplacement borehole, the location, orientation, and aperture of the fractures of the rock mass should be known. Borehole television and borescope surveys were performed to map the location, orientation, and aperture of the fractures intersecting the boreholes drilled in the Prototype Engineered Barrier System Field Tests (PEBSFT) at G-Tunnel. Core logging was also performed during drilling. However, because the core was not oriented and the depth of the fracture cannot be accurately determined, the results of the core logging were only used as reference and will not be discussed here

    After reading this article, the participant should be able to: 1. Demonstrate an understanding of some of the changes in aspects of facial fracture management. 2. Assess a patient presenting with facial fractures. 3. Understand indications and timing of surgery. 4. Recognize exposures of the craniomaxillofacial skeleton. 5. Identify methods for repair of typical facial fracture patterns. 6. Discuss the common complications seen with facial fractures. Restoration of the facial skeleton and associated soft tissues after trauma involves accurate clinical and radiologic assessment to effectively plan a management approach for these injuries. When surgical intervention is necessary, timing, exposure, sequencing, and execution of repair are all integral to achieving the best long-term outcomes for these patients.

    Fractures of the pisiform are often missed due to improper radiographic evaluation and a tendency to focus on other, more obvious injuries. Delayed diagnosis may result in disabling sequelae. A high index of clinical suspicion and appropriate radiographic examination will establish the correct diagnosis. Ten patients with pisiform fracture are presented. The anatomy, mechanism of injury, clinical presentation, radiographic features, and evaluation of this injury are discussed. (orig.)

    The diagnosis of a stress fracture should be considered in patients presented with pain after a change in activity, especially if the activity is strenuous and the pain is in the lower extremities. Since evidence of the stress fracture may not be apparent for weeks on routine radiographs, proper use of other imaging techniques will allow an earlier diagnosis. Prompt diagnosis is especially important in the femur, where displacement may occur

    There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India.

    Full Text Available Entanglement injury from local milling/grinding machine with a conveyor belt is a rare etiology of maxillofacial injuries. While there is abundant literature on industrial cause of trauma, entanglement injury as a mechanism has not been reported in the literature. We present two cases of maxillofacial injury secondary to entanglement of the loose apparel into the conveyor belt of the local grinding machine. The community should be aware of this rare cause of trauma, and adequate protection of children using these facilities should be enforced. One of such measure is to provide physical barriers to guard against these machines.

    Multifocal central giant cell granulomas (CGCG) in the maxillofacial region are suggestive of systemic disease such as hyperparathyroidism or an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome. Only 5 cases of multifocal CGCGs in the maxillofacial region without any concomitant systemic disease have currently been reported. We report here on an unusual case of 17-year-old man who presented with multifocal CGCGs of the bilateral posterior mandible and right maxilla and he was without any concomitant systemic disease

    There are few data available on the experience of minority surgeons in the field of oral and maxillofacial surgery (OMS). Therefore, the purpose of this study was to 1) explore factors that contribute to African Americans choosing OMS as a career, 2) examine satisfaction among minority oral and maxillofacial surgeons with the residency application and training process, 3) report on practice patterns among minority oral and maxillofacial surgeons, and 4) identify perceived bias for or against minority oral and maxillofacial surgeons in an attempt to aid the efforts of OMS residency organizations to foster diversity. A 19-item survey was sent to 80 OMS practitioners by use of information from the mailing list of the National Society of Oral and Maxillofacial Surgeons, an American Association of Oral and Maxillofacial Surgeons-affiliated organization. All surveys were sent by mail and were followed by a reminder mailing after 8 weeks. Responses returned within 16 weeks were accepted for analysis. Of the 80 mailed surveys, 41 were returned within the 16-week parameter, representing a return rate of 51%. Most of the minority surgeon respondents were married men with a mean age of 60 years who worked as private practitioners. Most respondents practiced on the eastern and western coasts of the United States. Exposure in dental school was the most important factor in selecting OMS as a specialty. Location and prestige were the most important factors in selecting a residency program. Most respondents reported that race did not affect the success of their application to a residency program and did not currently affect the success of their practice. However, 25 to 46% of participants experienced race-related harassment, and 48 to 55% of participants believed there was a bias against African Americans in OMS. Our data suggest that a substantial number of minority oral and maxillofacial surgeons subjectively perceive race-based bias in their career, although it does not

    The anatomic complexity of the maxillofacial region makes the retrieval of foreign bodies a daunting task for the maxillofacial Surgeon. Moreover the inability of 2-dimensional imaging to precisely locate foreign bodies makes it challenging. The anatomic proximity of critical structures and esthetic considerations limits the access and thus poses a greater challenge for the surgeon in cases of foreign body retrieval. Hereby we propose a simple technique and a case report to support, the retrieval of small (mobile C arm Fluoroscopy and a needle triangulation method to precisely locate a loosened miniplate screw in the mandibular angle region.

    Gender discrimination continues to be a challenge faced by women in oral and maxillofacial surgery. The discrimination itself is perpetrated by a small number of individuals, but it is lack of support and intervention by other surgeons that allows this to continue. The social norms approach is one means to break this cycle: first by identifying misperceptions and then by encouraging individuals to intervene instead of remaining bystanders. To move forward as a specialty, we must actively intervene when discrimination and harassment occur. Copyright © 2018 American Association of Oral and Maxillofacial Surgeons.

    The advance of clinical diagnosis and treatment in oral and maxillofacial-head and neck tumors has been through the process of specialization and multidisciplinary cooperation. In most cases, a single discipline cannot meet the requirements of diagnosis and treatment, which needs the cooperation of oral and maxillofacial surgery, otolaryngology and oncology approach and therapeutic method such as surgery, radiotherapy and chemotherapy. Holistic integrative medicine aims at integrating the most effective clinical practice experience and patients' individual situation and prognosis, establishing new medical mode conforming to the modern concept and fulfilling the medical system adapting to the specific characteristics of the diseases.

    Full Text Available History of present illness: A 25-year-old, right-handed male presented to the emergency department with left wrist pain after falling from a skateboard onto an outstretched hand two-weeks prior. He otherwise had no additional concerns, including no complaints of weakness or loss of sensation. On physical exam, there was tenderness to palpation within the anatomical snuff box. The neurovascular exam was intact. Plain films of the left wrist and hand were obtained. Significant findings: The anteroposterior (AP plain film of this patient demonstrates a full thickness fracture through the middle third of the scaphoid (red arrow, with some apparent displacement (yellow lines and subtle angulation of the fracture fragments (blue line. Discussion: The scaphoid bone is the most commonly fractured carpal bone accounting for 70%-80% of carpal fractures.1 Classically, it is sustained following a fall onto an outstretched hand (FOOSH. Patients should be evaluated for tenderness with palpation over the anatomical snuffbox, which has a sensitivity of 100% and specificity of 40%.2 Plain films are the initial diagnostic modality of choice and have a sensitivity of 70%, but are commonly falsely negative in the first two to six weeks of injury (false negative of 20%.3 The Mayo classification organizes scaphoid fractures as involving the proximal, mid, and distal portions of the scaphoid bone with mid-fractures being the most common.3 The proximal scaphoid is highly susceptible to vascular compromise because it depends on retrograde blood flow from the radial artery. Therefore, disruption can lead to serious sequelae including osteonecrosis, arthrosis, and functional impairment. Thus, a low threshold should be maintained for neurovascular evaluation and surgical referral. Patients with non-displaced scaphoid fractures should be placed in a thumb spica splint.3 Patients with even suspected scaphoid fractures should be placed in a thumb spica splint and re

    In maxillofacial surgery, children represent a special group of patients, as they have significant differences from adults as far as the facial skeleton is concerned. The etiology and epidemiology of pediatric trauma involving the facial skeleton has been reported in a large series of patients. Nevertheless, few of these reports review large numbers of pediatric patients, and little is known about treatment protocols for fractures in children. The aims of this study were to retrospectively analyze the treatment methods and outcomes of pediatric mandibular fractures in children and young adolescents up to the age of 15 years, to discuss the findings, and to propose treatment protocols for maxillofacial fractures in childhood. The present study retrospectively analyzed the treatment methods and outcome of the pediatric mandibular fractures in children and young adolescents' up to the age of 15 years over a period of 5 years. All patients were followed up for an average period of 18 months, with a maximum follow-up of 2 years. A total of 74 patients were treated for mandibular and dentoalveolar fractures in children upto the age of 15 years at the Department of Oral and Maxillofacial Surgery at Nair Hospital Dental College, Mumbai from 2007 to 2012. AND CONCLUSIONS: The treatment methods used at our centre had satisfactory outcomes at the end of a follow-up period of 2 years. Reported complications were minimal. Our results confirm the usefulness of open reduction and plate fixation in older children (>12 years of age) and a conservative approach in younger children (≤12 years of age) in treating mandibular fractures.

    Ibuprofen is used for the treatment of non-serious pain. This study assessed the efficacy and safety of a new ibuprofen plaster for the treatment of pain associated with acute sports impact injuries/contusions. In this randomised, double-blind, multi-centre, placebo controlled, parallel group study, adults (n = 130; 18-58 years of age) diagnosed with acute sports-related blunt soft tissue injury/contusion were randomized to receive either ibuprofen 200 mg plaster or placebo plaster. Plasters were administered once daily for five consecutive days. The primary assessment was area under the visual analogue scale (VAS) of pain on movement (POM) over 0 to three days (VAS AUC 0-3d ). Other endpoints included algometry AUC from 0 to three days (AUC 0-3d ) and 0 to five days (AUC 0-5d ), to evaluate improvement of sensitivity at the injured site, and patient and investigator global assessment of efficacy. Safety was monitored throughout the study. The ibuprofen plaster resulted in superior reduction in AUC 0-3d compared with placebo; the Least Squares (LS) mean difference was 662.82 mm*h in favour of the ibuprofen 200mg plaster (P = 0.0011). The greater improvement in VAS AUC of POM was also observed after 12 h, 24 h, and five days of therapy. Tenderness also significantly improved with the ibuprofen plaster compared with placebo; LS mean difference in algometry/tenderness AUC 0-3d was 1.87 N/cm 2 *d and AUC 0-5d was 1.87 N/cm 2 *d (P values ≤0.0004). At all study timepoints, a greater percentage of patients and investigators rated the effectiveness of the ibuprofen 200 mg plaster as good/excellent than the placebo plaster. Treatment-emergent adverse events for the ibuprofen plaster were few (≤1.5%) and were mild in severity. The results of this study indicate 200 mg plaster is effective and safe for the treatment of pain due to acute sports-related traumatic blunt soft tissue injury/contusion in adults.

    Full Text Available Incidence rate of symphysis mandible fracture in children was about 15 – 20%. Boys are effected twice as frequently as girls. The pattern of craniomaxillofacial fractures seen in children varies with evolving skeletal anatomy and socioenvironmental factors. The treatment of pediatric maxillofacial fractures is due to physiological, developmental, and anatomical characteristic of children. Management of pediatric mandible fracture by anatomic reduction is combine with stabilization adequate to maintain it until bone union has occured. This case report is aimed to explain about the management of simphysis mandible fracture in pediatric using erich arch bar. A 12 years old boy has fracture in mandible due to accident with mechanisme the chin hit the touching motorcyle tank. Clinically, was a deformity at the anterior of mandible and malocclusion has occured. Patient also complaint a  pain with swelling and bleeding at the regio of fracture and lip. Suturing was done  in wound area intra and extra oral, followed by application of arch bar in maxilla and mandible. Control at the third day was found a vague fracture line in panoramic radiograph. Management of emergency trauma in oral and maxillofacial surgery was based on principle of ATLS was done in this case. Following treatment was application of erich arch bar for mobility reducing the fracture of mandible symphisis. Management of mandibular symphisis fracture in 12 years old children with full eruption of teeth has been given a good healing  due to the teeth  was act to develop retention and stabilize the erich arch bar. Management of pediatric simphysis mandible fracture for 12 years old children with full eruption of teeth using erich bar revealed a healed fracture.

  9. Connectomic markers of symptom severity in sport-related concussion: Whole-brain analysis of resting-state fMRI

    Full Text Available Concussion is associated with significant adverse effects within the first week post-injury, including physical complaints and altered cognition, sleep and mood. It is currently unknown whether these subjective disturbances have reliable functional brain correlates. Resting-state functional magnetic resonance imaging (rs-fMRI has been used to measure functional connectivity of individuals after traumatic brain injury, but less is known about the relationship between functional connectivity and symptom assessments after a sport concussion. In this study, rs-fMRI was used to evaluate whole-brain functional connectivity for seventy (70 university-level athletes, including 35 with acute concussion and 35 healthy matched controls. Univariate analyses showed that greater symptom severity was mainly associated with lower pairwise connectivity in frontal, temporal and insular regions, along with higher connectivity in a sparser set of cerebellar regions. A novel multivariate approach also extracted two components that showed reliable covariation with symptom severity: (1 a network of frontal, temporal and insular regions where connectivity was negatively correlated with symptom severity (replicating the univariate findings; and (2 a network with anti-correlated elements of the default-mode network and sensorimotor system, where connectivity was positively correlated with symptom severity. These findings support the presence of connectomic signatures of symptom complaints following a sport-related concussion, including both increased and decreased functional connectivity within distinct functional brain networks.

    Title IX, the commercialization of sports, the social change in sports participation, and the response to the obesity epidemic have contributed to the rapid proliferation of participation in both competitive organized sports and nontraditional athletic events. As a consequence, emergency physicians are regularly involved in the acute diagnosis, management, disposition, and counseling of a broad range of sports-related pathology. Three important and highly publicized mechanisms of injury in sports relevant to emergency medicine (EM) include concussion, heat illness, and sudden cardiac death. In conjunction with the 2014 Academic Emergency Medicine consensus conference "Gender-specific Research in Emergency Care: Investigate, Understand, and Translate How Gender Affects Patient Outcomes," a consensus group consisting of experts in EM, emergency neurology, sports medicine, and public health convened to deliberate and develop research questions that could ultimately advance the field of sports medicine and allow for meaningful application in the emergency department (ED) clinical setting. Sex differences in injury risk, diagnosis, ED treatment, and counseling are identified in each of these themes. This article presents the consensus-based priority research agenda. © 2014 by the Society for Academic Emergency Medicine.

    Regular participation in sport, exercise and physical activity is associated with positive health outcomes and form a mainstay of British public health policies. However, regular participation in sport and exercise can result in sport related injury (SRI) which, in turn, is a key cause of exercise cessation. The integration of Sport and Exercise Medicine (SEM) in the English National Health Service (NHS) aims to provide a specialist service for public populations and thus reduce the impact of SRI on exercise cessation and associated negative health outcomes. More broadly it aims to both support physical activity health promotion policies and improve healthcare organisations efficiencies through providing the most condition-appropriate treatment. This qualitative interview study examines patients' (n=19) experiences of accessing and receiving SEM treatment within the English NHS. The research demonstrates that referral pathways into SEM were often prolonged, characterised by multiple General Practitioner (GP) visits and referrals into other musculoskeletal services, demonstrating an inefficient use of healthcare resources. Prolonged pathways fostered only limited recovery back to previous physical activity levels and other negative health behaviours, yet on accessing the SEM clinic, patients experienced progressive rehabilitation back into sport and exercise participation. This study highlights the importance of more fully integrating SEM services into public healthcare as a way of improving the organisational capacity of healthcare in treating SRI and ensuring that citizens comply with state interventions which orchestrate health management through raising physical activity levels across the population.

    Recent guidelines advocate sports medicine professionals to use balance tests to assess sensorimotor status in the management of concussions. The present study sought to determine whether a low-cost balance board could provide a valid, reliable, and objective means of performing this balance testing. Criterion validity testing relative to a gold standard and 7 day test-retest reliability. University biomechanics laboratory. Thirty healthy young adults. Balance ability was assessed on 2 days separated by 1 week using (1) a gold standard measure (ie, scientific grade force plate), (2) a low-cost Nintendo Wii Balance Board (WBB), and (3) the Balance Error Scoring System (BESS). Validity of the WBB center of pressure path length and BESS scores were determined relative to the force plate data. Test-retest reliability was established based on intraclass correlation coefficients. Composite scores for the WBB had excellent validity (r = 0.99) and test-retest reliability (R = 0.88). Both the validity (r = 0.10-0.52) and test-retest reliability (r = 0.61-0.78) were lower for the BESS. These findings demonstrate that a low-cost balance board can provide improved balance testing accuracy/reliability compared with the BESS. This approach provides a potentially more valid/reliable, yet affordable, means of assessing sports-related concussion compared with current methods.

    Dagfinn Aarksog first described faciodigitogenital syndrome in 1970. Its inheritance is X linked and autosomally recessive. Currently, the diagnosis of Aarskog-Scott syndrome (ASS) is based on clinical dysmorphologic findings and can be supported by genetic examination. This report describes 3 brothers already diagnosed with ASS who were referred for examination of oral and maxillofacial malformations associated with ASS. They presented classic features of ASS, such as digital and genital (shawl scrotum) anomalies. More specifically, in terms of orbitopalpebral malformations, they showed marked ptosis with hypertelorism and antimongoloid palpebral fissure that gave them the characteristic facies. Concerning their oral and maxillofacial malformations, they had dental and skeletal major discrepancies and some dental agenesia. ASS is a rare X-linked syndrome composed of numerous morphologic facial, digital, and genital anomalies. The diagnosis is established genetically with the FGD1 mutation but there is no phenotypic and genotypic correlation with FGD1 mutations. Concerning maxillofacial malformations, maxillary and mandibular hypoplasia with jaw discrepancies can be found, as can teeth anomalies. It seems that these anomalies are widely underestimated.

    Four hundred and thirty trochanteric factures operated upon with McLaughlin, Ender or Richard's osteosynthesis were divided into 6 different types based on their radiographic appearance before and immediately after reposition with special reference to the medial cortical support. A significant correlation was found between the fracture type and subsequent mechanical complications where types 1 and 2 gave less, and types 4 and 5 more complications. A comparison of the various osteosyntheses showed that Richard's had significantly fewer complications than either the Ender or McLaughlin types. For Richard's osteosynthesis alone no correlation to fracture type could be made because of the small number of complications in this group. (orig.)

    Full Text Available Fracture blisters are a relatively uncommon complication of fractures in locations of the body, such as the ankle, wrist elbow and foot, where skin adheres tightly to bone with little subcutaneous fat cushioning. The blister that results resembles that of a second degree burn.These blisters significantly alter treatment, making it difficult to splint or cast and often overlying ideal surgical incision sites. Review of the literature reveals no consensus on management; however, most authors agree on early treatment prior to blister formation or delay until blister resolution before attempting surgical correction or stabilization.

    Citation analysis helps to identify the research trends within a research field and helps to identify the most frequently occurring parameters. The aim of this study was to identify the 100 most-cited articles in the field of dental, oral, and maxillofacial traumatology over the past 64 years. A comprehensive list of the most-cited articles in dental, oral, and maxillofacial trauma was compiled using 'All Databases' section of the ISI Web of Knowledge. Related articles were considered to be those articles in which part or all of the experiment or study was related to dental and/or oral and maxillofacial trauma. In case reports, if a part of a treatment plan was related to the topic, that article was considered to be relevant. The characteristics analyzed included number of citations, authors, journals, institution, country of origin, publication year, article type, study material, and topic. The number of citations for each article ranged from 69 to 229. The journal Dental Traumatology was the most represented, followed by the journal Oral and Maxillofacial Surgery. Of the 100 articles, 83% were original articles, 15% were review articles, and 2% were case report/case series. Therapy and prognosis-related topics were the most common topics. Most articles came from institutions in the United States, followed by the Scandinavian countries. University Hospital of Copenhagen was the source of the highest number (34) of the most-cited articles; the same author wrote or co-wrote 22 of the 100 most-cited articles. The list of most-cited articles in the field of dental, oral, and maxillofacial traumatology gives a good scientometric picture of trauma research in the world. A large number of the most-cited articles are mainly from the field of dental traumatology and originate from a few research teams. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The aim of this retrospective study was to assess recovery of mouth opening after closed treatment of fractures of the mandibular condyle, and analyse which characteristics might influence recovery. We measured mouth opening in 142 patients (mean (SD) age 30 (14) years, 96 of whom were male) during follow-up at 3, 6, 13, 26, and 52 weeks after the injury. Fractures were assessed on radiographs. Data were analysed using a multilevel analysis. Half the fractures were of the low condylar neck (n=71). Thirty-seven patients had bilateral condylar fractures, 29 had dislocated fractures, and in 80 the fracture was displaced. One or more additional mandibular fractures were present in 68. During follow-up mean (SD) mouth opening increased to: 33.6 (9.6) at 3 weeks, 40.1 (10.0) at 6 weeks, 45.1 (9.6) at 13 weeks, 49.8 (9.5) at 26 weeks, and 52.6 (7.5) at 52 weeks. Older age, female sex, displaced fracture, bilateral fractures, additional mandibular fractures, and the interaction between follow-up time and additional mandibular fractures, were predictors of a less favourable recovery of mouth opening. Clinicians can use the results of this study to predict recovery of mouth opening after closed treatment of fractures of the mandibular condyle at first consultation.

    We evaluated the usefulness of the unsharp masking technique as a preprocessing filter to improve 3D-CT images of bony structure in the maxillofacial region. The effect of the unsharp masking technique with several combinations of mask size and weighting factor on image resolution was investigated using a spatial frequency phantom made of bone-equivalent material. The 3D-CT images were obtained with scans perpendicular to and parallel to the phantom plates. The contrast transfer function (CTF) and the full width at half maximum (FWHM) of each spatial frequency component were measured. The FWHM was expressed as a ratio against the actual thickness of phantom plate. The effect on pseudoforamina was assessed using sliced CT images obtained in clinical bony 3D-CT examinations. The effect of the unsharp masking technique on image quality was also visually evaluated using five clinical fracture cases. CTFs did not change. FWHM ratios of original 3D-CT images were smaller than 1.0, regardless of the scanning direction. Those in scans perpendicular to the phantom plates were not changed by the unsharp masking technique. Those in parallel scanning were increased by mask size and weighting factor. The area of pseudoforamina decreased with increases in mask size and weighting factor. The combination of mask size 3 x 3 pixels and weighting factor 5 was optimal. Visual evaluation indicated that preprocessing with the unsharp masking technique improved the image quality of the 3D-CT images. The unsharp masking technique is useful as a preprocessing filter to improve the 3D-CT image of bony structure in the maxillofacial region. (author)

    The management of pediatric mandibular fractures is challenging for maxillofacial surgeons due to ongoing mandibular growth involving tooth buds. The treatment of such fractures has been a topic of much research. Generally accepted methods for the treatment of mandibular parasymphyseal or symphyseal fractures in children are conservative approaches involving the use of acrylic splints, lateral compression with an open-cap splint stabilized by circummandibular wiring, and maxillomandibular fixation with an arch bar and eyelet wiring. The aim of this technical note was to describe a straightforward approach to the treatment of pediatric mandibular fractures, in which an occlusal splint is secured to prevent trauma to the soft tissue, without the need for general anesthesia.

    Sport participation is associated with a risk of sports-related injuries and illnesses, and Paralympic athletes' additional medical issues can be a challenge to health care providers and medical staff. However, few prospective studies have assessed sports-related injuries and illnesses in Paralympic sport (SRIIPS) over time. Advances in mobile phone technology and networking systems offer novel opportunities to develop innovative eHealth applications for collection of athletes' self-reports. Using eHealth applications for collection of self-reported SRIIPS is an unexplored area, and before initiation of full-scale research of SRIIPS, the feasibility and usability of such an approach needs to be ascertained. The aim of this study was to perform a 4-week pilot study and (1) evaluate the monitoring feasibility and system usability of a novel eHealth application for self-reported SRIIPS and (2) report preliminary data on SRIIPS. An eHealth application for routine collection of data from athletes was developed and adapted to Paralympic athletes. A 4-week pilot study was performed where Paralympic athletes (n=28) were asked to weekly self-report sport exposure, training load, general well-being, pain, sleep, anxiety, and possible SRIIPS. The data collection was followed by a poststudy use assessment survey. Quantitative data related to the system use (eg, completed self-reports, missing responses, and errors) were analyzed using descriptive statistics. The qualitative feasibility and usability data provided by the athletes were condensed and categorized using thematic analysis methods. The weekly response rate was 95%. The athletes were of the opinion that the eHealth application was usable and feasible but stated that it was not fully adapted to Paralympic athletes and their impairments. For example, it was difficult to understand how a new injury or illness should be identified when the impairment was involved. More survey items related to the impairments were

    Limited data exist comparing the performance of computerized neurocognitive tests (CNTs) for assessing sport-related concussion. We evaluated the reliability and validity of three CNTs-ANAM, Axon Sports/Cogstate Sport, and ImPACT-in a common sample. High school and collegiate athletes completed two CNTs each at baseline. Concussed (n=165) and matched non-injured control (n=166) subjects repeated testing within 24 hr and at 8, 15, and 45 days post-injury. Roughly a quarter of each CNT's indices had stability coefficients (M=198 day interval) over .70. Group differences in performance were mostly moderate to large at 24 hr and small by day 8. The sensitivity of reliable change indices (RCIs) was best at 24 hr (67.8%, 60.3%, and 47.6% with one or more significant RCIs for ImPACT, Axon, and ANAM, respectively) but diminished to near the false positive rates thereafter. Across time, the CNTs' sensitivities were highest in those athletes who became asymptomatic within 1 day before neurocognitive testing but was similar to the tests' false positive rates when including athletes who became asymptomatic several days earlier. Test-retest reliability was similar among these three CNTs and below optimal standards for clinical use on many subtests. Analyses of group effect sizes, discrimination, and sensitivity and specificity suggested that the CNTs may add incrementally (beyond symptom scores) to the identification of clinical impairment within 24 hr of injury or within a short time period after symptom resolution but do not add significant value over symptom assessment later. The rapid clinical recovery course from concussion and modest stability probably jointly contribute to limited signal detection capabilities of neurocognitive tests outside a brief post-injury window.

    Adolescence is considered to be the most important period for the prevention of substance use and misuse (SUM). The aim of this study was to investigate the problem of SUM and to establish potentially important factors associated with SUM in Kosovar adolescents. Multi-stage simple random sampling was used to select participants. At the end of their high school education, 980 adolescents (623 females) ages 17 to 19 years old were enrolled in the study. The prevalence of smoking, alcohol consumption (measured by Alcohol Use Disorder Identification Test-AUDIT), and illegal drug use (dependent variables), as well as socio-demographic, scholastic, familial, and sports-related factors (independent variables), were assessed. Boys smoke cigarettes more often than girls with daily-smoking prevalence of 16% among boys and 9% among girls (OR = 1.85, 95% = CI 1.25-2.75). The prevalence of harmful drinking (i.e., AUDIT scores of >10) is found to be alarming (41% and 37% for boys and girls, respectively; OR = 1.13, 95% CI = 0.87-1.48), while 17% of boys and 9% of girls used illegal drugs (OR = 2.01, 95% CI = 1.35-2.95). The behavioral grade (observed as: excellent-average-poor) is the factor that was most significantly correlated with SUM both in boys and girls, with lower behavioral grades among those adolescents who consume substances. In girls, lower maternal education levels were associated with a decreased likelihood of SUM, whereas sports achievement was negatively associated with risky drinking. In boys, sports achievement decreased the likelihood of daily smoking. Information on the factors associated with SUM should be disseminated among sports and school authorities.

    To investigate the efficacy and safety of a recently developed ibuprofen medicated plaster in the treatment of acute sports impact injuries/contusions. In this double-blind, multi-center, placebo-controlled, parallel group, phase 3 study (EudraCT Number: 2012-003257-2) patients (n = 132; ages 18 to 60 years) diagnosed with acute sports-related traumatic blunt soft tissue injury/contusion to the upper or lower limbs were randomized to receive either ibuprofen 200 mg plaster (n = 64) or placebo plaster (n = 68). Plasters were administered once daily for five consecutive days. The primary assessment was the area under the curve (AUC) of the visual analogue scale (VAS) of pain on movement (POM) over 0 to 72 h (VAS 0-72 ). The ibuprofen medicated plaster was associated with a reduction in pain on movement (POM) based on lower VAS AUC 0-72h (2399.4 mm*h) compared with placebo (4078.9 mm*h) (least squares mean difference: - 1679.5 mm*h; P ibuprofen medicated plaster compared with placebo at 12, 48, 24, and 120 h (P ibuprofen medicated plaster was associated with greater reduction in tenderness/pain than placebo at each timepoint (P values ibuprofen plaster, and n = 6 [8.8%] for placebo). All drug-related AEs were administration site reactions and were mild in intensity. The results of this study indicate that ibuprofen medicated plaster results in rapid and clinically relevant reduction of pain in patients suffering from blunt musculoskeletal injuries or recurrent pain. The ibuprofen medicated plaster was well tolerated.

    Full Text Available Fracture of mandible can be classified according to its anatomical location, in which condylar fracture is the most common one overall and is missed on clinical examination. Due to the unique geometry of the mandible and temporomandibular joint, without treatment the fractures can result in marked pain, dysfunction, and deformity. The condylar fracture may be further classified depending on the sides involved: unilateral/bilateral, depending on the height of fracture: intracapsular (within the head of condyle, extracapsular - head and neck (high condyle fracture, and subcondylar (low condyle fracture, and depending on displacement: nondisplaced, displaced (anteromedially, medially, and lateral, and dislocated. The clinical features include swelling and tenderness over the temporomandibular joint region, restricted mouth opening, and anterior open bite. A 34-year-old male patient reported to the Department of Oral and Maxillofacial Surgery at Madha Dental College and Hospital; suffered fall trauma resulting in bilateral condyle fracture, dentoalveolar fracture in mandible with restricted mouth opening, and anterior open bite.

    Le Fort-type fractures are very rare in children, and there is a paucity of literature presenting their frequency and characteristics. The purpose of this study was to determine the etiology, frequency, and fracture patterns of children with severe facial trauma associated with pterygoid plate fractures in a pediatric cohort. We performed a retrospective cohort study of all children aged younger than 16 years with pterygoid plate and facial fractures who presented to our institute between 1990 and 2010. Patient charts and radiologic records were reviewed for demographic and fracture characteristics. Patients were categorized into 2 groups as per facial fracture pattern: non-Le Fort-type fractures (group A) and Le Fort-type fractures (group B). Other variables including dentition age, frontal sinus development, mechanism of injury, injury severity, and concomitant injuries were recorded. Univariate methods were used to compare groups. We identified 24 children; 25% were girls, and 20.8% were of nonwhite race. Most presented with Le Fort-type fracture patterns (group B, 66.7%). Age was significantly different between group A and group B (mean, 5.9 years and 9.9 years, respectively; P = .009). No significant differences in Injury Severity Score, rate of operative repair, and length of stay were found between groups. Most children with severe facial fractures and pterygoid plate fractures presented with Le Fort-type fracture patterns in our cohort. The mean age of children with Le Fort-type fractures was greater than in those with non-Le Fort-type patterns. However, Le Fort-type fractures did occur in younger children with deciduous and mixed dentition. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

    To investigate the operative method and short-term effectiveness in the surgical treatment of Maisonneuve fracture. Between January 2010 and February 2013, 23 patients with Maisonneuve fracture were treated. There were 14 males and 9 females with an average age of 40.3 years (range, 30-68 years). The causes of injuries were falling injury in 11 patients, sports related injury in 5 patients, traffic accident injury in 4 patients, and falling injury from height in 3 patients. The interval between injury and operation was 7-10 days (mean, 8.5 days). All of fractures were closed. Three patients had combined injury of deltoid ligament. The surgical procedures included surgical reduction and fixation of medial malleolus fracture and posterior malleolus fracture, repair of the deltoid ligament with ground anchor suture, and fixation of the disrupted distal tibiofibular syndesmosis. All incisions achieved primary healing, no postoperative complications such as infection occurred. Twenty-one patients were followed up 24-36 months (mean, 26.5 months). No patients complained of pain, tenderness, and obvious swelling of the ankle. At 3-6 months (mean, 4.6 months) after operation, X-ray films showed bony union of fractures and normal mortises in 21 patients. And no traumatic arthritis was observed with reliable fixation. The range of motion of ankle dorsi flexion and plantar flexion was 30-40 degrees) (mean, 34.5 degrees) Baird-Jackson anide functional score was 85-100 (mean, 94); 16 cases were rated as excellent, 4 as good, and 1 as fair with an excellent and good rate of 95.2%. Surgical treatments of Maisonneuve fracture include surgical reduction and fixation of the medial malleolus and posterior malleolus, repair of the deltoid ligament and fixation of the disrupted distal tibiofibular syndesmosis, and good effectiveness can be achieved.

    This book entitle ''Fracture Mechanics'', the first one of the monograph ''Materiologie'' is geared to design engineers, material engineers, non destructive inspectors and safety experts. This book covers fracture mechanics in isotropic homogeneous continuum. Only the monotonic static loading is considered. This book intended to be a reference with the current state of the art gives the fundamental of the issues under concern and avoids the developments too complicated or not yet mastered for not making reading cumbersome. The subject matter is organized as going from an easy to a more complicated level and thus follows the chronological evolution in the field. Similarly the microscopic scale is considered before the macroscopic scale, the physical understanding of phenomena linked to the experimental observation of the material preceded the understanding of the macroscopic behaviour of structures. In this latter field the relatively recent contribution of finite element computations with some analogy with the experimental observation is determining. However more sensitive analysis is not skipped

    3-dimensional models (3D) appeared in the medical field 20 years ago. The recent development of consumer 3D printers explains the renewed interest in this technology. We describe the technical and practical modalities of this surgical tool, illustrated by concrete examples. The OsiriX(®) software (version 5.8.5, Geneva, Switzerland) was used for 3D surface reconstruction of the area of interest, the generation and export of ".stl" file. The NetFabb(®) software (Basic version 5.1.1, Lupburg, Germany) provided the preparation of ".stl" file. The 3D-printer was an Up plus 2 Easy 120(®) (PP3DP, Beijing Technology Co. TierTime Ltd., Chine). The printer used fused deposition modeling. The softwar Up!(®) allowed the 3d impression as required. The first case illustrated the value of 3D printing in the upper (frontal sinus and orbital roof). The second case concerned the preconfiguration of the osteosynthesis material for a complex fracture of the midface through the "mirroring" system. The third case showed the conformation of a prereconstruction for segmental mandibulectomy. Current 3D-printers are easy to use and represent a promising solution for medical prototyping. The 3D printing will quickly become undeniable because of its advantages: information sharing, simulation, surgical guides, pedagogy. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    The objective of this study was to evaluate spiral-computed tomography (3D-CT) images of 20 patients presenting with cysts and tumors in the maxillofacial complex, in order to compare the surface and volume techniques of image rendering. The qualitative and quantitative appraisal indicated that the volume technique allowed a more precise and accurate observation than the surface method. On the average, the measurements obtained by means of the 3D volume-rendering technique were 6.28% higher than those obtained by means of the surface method. The sensitivity of the 3D surface technique was lower than that of the 3D volume technique for all conditions stipulated in the diagnosis and evaluation of lesions. We concluded that the 3D-CT volume rendering technique was more reproducible and sensitive than the 3D-CT surface method, in the diagnosis, treatment planning and evaluation of maxillofacial lesions, especially those with intra-osseous involvement.

    Full Text Available Central giant cell granuloma (CGCG is a benign proliferation of fibroblasts and multinucleated giant cells that almost exclusively occurs in the jaws. It commonly occurs in young adults showing a female predilection in the anterior mandible. Multifocal CGCGs in maxillofacial region are very rare and suggestive of systemic diseases such as hyperparathyroidism, an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome or other disorders. Only 10 cases of multifocal CGCGs in the maxillofacial region without any concomitant systemic disease have been reported in the English literature. Here, we report an unusual case of 36 year-old female presented with non-syndromic synchronous, multifocal CGCGs in the left posterior mandible and left posterior maxilla without any concomitant systemic disease. Relevant literature is reviewed and the incidence, clinical features, radiological features, differential diagnosis and management of CGCGs are discussed.

    2012-01-31

    The objective of this 10 year, retrospective study is to evaluate the indications for the removal of titanium miniplates following osteosynthesis in maxillofacial trauma and orthognathic surgery. All patients who had miniplates placed in a Regional Oral and Maxillofacial Department between January 1998 and October 2007 were included. The following variables were recorded: patient gender and age, number of plates inserted, indications for plate placement, location of plates, number and location of plates removed, indications for plate removal, time between insertion and removal, medical co-morbidities, and the follow-up period. During the 10 years of the study, 1247 titanium miniplates were placed in 535 patients. A total of 32 (3%) plates were removed from 30 patients. Superficial infection accounted for 41% of all plates removed. All complications were minor and most plates were removed within the first year of insertion. A low removal rate of 3% suggests that the routine removal of asymptomatic titanium miniplates is not indicated.

    Review of a case of paraosseous extramedullary hematopoiesis (EMH) affecting the maxillary sinuses and retro-orbital spaces imitating bilateral orbital cellulitis. Maxillofacial EMH causes diagnostic/therapeutic challenges. This case report describes a 4-year-old African American male with sickle cell disease (HbSS) who presented with bilateral orbitofacial swelling. Diagnosis was made with imaging and confirmed with tissue sampling. Partial exchange transfusion was utilized to stop the progression of maxillofacial EMH and to treat the patient's chronic anemia. Follow-up MRI showed regression of orbital and retro-orbital involvement. Early treatment with conservative modalities and close observation may prevent need for more invasive treatments.

    For many procedures, lasers are now becoming the treatment of choice by both clinicians and patients, and in some cases, the standard of care. This clinical study was carried out at Department of Maxillofacial Surgery, Ramadi Teaching Hospital, Rashid Private Hospital and Razi Private Hospital, Anbar Health Directorate, Anbar Province, Iraq. A total of 32 patients including 22 (≈ 70%) male and 10 (≈ 30%) female with age range from 5 months to 34 years old. Chirolas 20 W diode laser emitting at 980 nm was used. Our preliminary clinical findings include sufficient hemostasis, coagulation properties, precise incision margin, lack of swelling, bleeding, pain, scar tissue formation and overall satisfaction were observed in the clinical application. The clinical application of the diode (980 nm) laser in maxillofacial surgery proved to be of beneficial effect for daily practice and considered practical, effective, easy to used, offers a safe, acceptable, and impressive alternative for conventional surgical techniques.

    Currently, oral and maxillofacial surgery (OMFS) still poses a significant challenge for surgeons due to the anatomic complexity and limited field of view of the oral cavity. With the great development of computer technologies, he computer-aided surgery has been widely used for minimizing the risks and improving the precision of surgery. Areas covered: The major goal of this paper is to provide a comprehensive reference source of current and future development of computer-aided OMFS including surgical planning, simulation and navigation for relevant researchers. Expert commentary: Compared with the traditional OMFS, computer-aided OMFS overcomes the disadvantage that the treatment on the region of anatomically complex maxillofacial depends almost exclusively on the experience of the surgeon.

    2009-01-01

    Extensive maxillofacial defects resulting from trauma or oncologic resection present reconstructive challenges. Various autografts and alloplastic materials in conjunction with standard soft-tissue techniques have been used in the reconstruction of these types of defects. Polyetheretherketone (PEEK) is a semicrystalline polyaromatic linear polymer exhibiting an excellent combination of strength, stiffness, durability, and environmental resistance. Recent investigations of PEEK as a biomaterial resulted in the successful treatment of cervical disk disease. We describe a series of 4 patients whose defects were reconstructed using customized PEEK implants. All had excellent postoperative aesthetic and functional results without complications such as infections or extrusions. Because PEEK implants are customizable, easily workable, inert, and nonporous, they represent an ideal alloplastic material for maxillofacial reconstruction.

    We present a new model of guided surgery, exclusively using computer assistance, from the preoperative planning of osteotomies to the actual surgery with the aid of stereolithographic cutting guides and osteosynthetic miniplates designed and made preoperatively, using custom-made titanium miniplates thanks to direct metal laser sintering. We describe the principles that guide the designing and industrial manufacturing of this new type of osteosynthesis miniplates. The surgical procedure is described step-by-step using several representative cases of dento-maxillofacial dysmorphosis. The encouraging short-term results demonstrate the wide range of application of this new technology for cranio-maxillofacial surgery, whatever the type of osteotomy performed, and for plastic reconstructive surgery.

    The aim of the present study was to perform a bibliometric analysis of the gender distribution of first and senior authorships in important oral and maxillofacial journals over the 30-year period from 1980 to 2010. Articles published in three representative oral and maxillofacial surgery journals were selected. The years 1980, 1990, 2000, and 2010 were chosen as representative points in time for article selection. Original research, case reports, technical notes, and reviews were included in the analysis. Case reports and technical notes were pooled in one group. For each article, the gender of the first author as well as that of the senior author was determined, based on the inspection of their first name. The type of article was determined and the country of origin of the article was documented. A total 1412 articles were subjected to the data analysis. A significant increase in female authorship in oral and maxillofacial surgery could be identified over the chosen 30-year period. However, the number of publications by male authors was still significantly higher at all points of time, exceeding those of female authors by at least 3.8 fold in 2010. As there is a trend towards feminization of medicine and dentistry, the results of the present study may serve as the basis for further analysis of the current situation, and the identification of necessary actions to accelerate the closure of the gender gap in publishing in oral and maxillofacial surgery.

    Citation rate is one of several tools to measure academic productivity. The purposes of this study were to estimate and identify factors associated with citation rates in the oral and maxillofacial surgery (OMS) literature. This was a retrospective longitudinal study of publications in the Journal of Oral and Maxillofacial Surgery (JOMS), International Journal of Oral and Maxillofacial Surgery (IJOMS), and Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology (OOOO) from January through December 2012. The predictor variables were author- and article-specific factors. The outcome variable was the citation rate, defined as the total number of citations for each article over a 4-year period. Descriptive, bivariate, and multiple regression statistics were computed. The authors identified 993 articles published during 2012. The mean number of citations at 4 years after publication was 5.6 ± 5.3 (median, 4). In bivariate analyses, several author- and article-specific factors were associated with citation rates. In a multiple regression model adjusting for potential confounders and effect modifiers, first author H-index, number of authors, journal, OMS focus area, and Oxford level of evidence were significantly associated with citation rate (P ≤ .002). The authors identified 5 factors associated with citation rates in the OMS literature. These factors should be considered in context when evaluating citation-based metrics for OMS. Studies that focus on core OMS procedures (eg, dentoalveolar surgery, dental implant surgery), are published in specialty-specific journals (eg, JOMS or IJOMS), and have higher levels of evidence are more likely to be cited.

    Biomedical prototyping has resulted from a merger of rapid prototyping and imaging diagnosis technologies. However, this process is complex, considering the necessity of interaction between biomedical sciences and engineering. Good results are highly dependent on the acquisition of computed tomography images and their subsequent manipulation by means of specific software. The present study describes the experience of a multidisciplinary group of researchers in the acquisition and manipulation of computed tomography images of the maxillofacial region aiming at biomedical prototyping for surgical purposes.

    Maxillofacial and dental defects often have detrimental effects on patient health and appearance. A holistic approach of restoring lost dentition along with bone and soft tissue is now the standard treatment of these defects. Recent improvements in reconstructive techniques, especially osseointegration, microvascular free tissue transfer, and improvements in bone engineering, have yielded excellent functional and aesthetic outcomes. This article reviews the literature on these modern reconstructive and rehabilitation techniques.

    Mandibular fractures represent a substantial portion of facial fractures in the pediatric population. Pediatric mandibles differ from their adult counterparts in the presence of mixed dentition. Avoidance of injury to developing tooth follicles is critical. Simple mandibular fractures can be treated with intermaxillary fixation (IMF) using arch bars or bone screws. This report describes an alternative to these methods using silk sutures and an algorithm to assist in treating simple mandibular fractures in the pediatric population. A retrospective chart review was performed and the records of 1 surgeon were examined. Pediatric patients who underwent treatment for a mandibular fracture in the operating room from 2011 to 2015 were identified using Common Procedural Terminology codes. Data collected included age, gender, type of fracture, type of treatment used, duration of fixation, and presence of complications. Five patients with a mean age of 6.8 years at presentation were identified. Fracture types were unilateral fractures of the condylar neck (n = 3), bilateral fractures of the condylar head (n = 1), and a unilateral fracture of the condylar head with an associated parasymphyseal fracture (n = 1). IMF was performed in 4 patients using silk sutures, and bone screw fixation was performed in the other patient. No post-treatment complications or malocclusion were reported. Average duration of IMF was 18.5 days. An algorithm is presented to assist in the treatment of pediatric mandibular fractures. Silk suture fixation is a viable and safe alternative to arch bars or bone screws for routine mandibular fractures. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

    Microvascular surgery following tumor resection has become an important field of oral maxillofacial surgery (OMFS). Following the surveys on current reconstructive practice in German-speaking countries and Europe, this paper presents the third phase of the project when the survey was conducted globally. The DOESAK questionnaire has been developed via a multicenter approach with maxillofacial surgeons from 19 different hospitals in Germany, Austria and Switzerland. It was distributed in three different phases to a growing number of maxillofacial units in German-speaking clinics, over Europe and then worldwide. Thirty-eight units from Germany, Austria and Switzerland, 65 remaining European OMFS-departments and 226 units worldwide responded to the survey. There is wide agreement on the most commonly used flaps, intraoperative rapid sections and a trend towards primary bony reconstruction. No uniform concepts can be identified concerning osteosynthesis of bone transplants, microsurgical techniques, administration of supportive medication and postoperative monitoring protocols. Microsurgical reconstruction is the gold standard for the majority of oncologic cases in Europe, but worldwide, only every second unit has access to this technique. The DOESAK questionnaire has proven to be a valid and well accepted tool for gathering information about current practice in reconstructive OMFS surgery. The questionnaire has been able to demonstrate similarities, differences and global inequalities. Copyright © 2015 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

    Academic promotion is linked to research productivity. The purpose of this study was to assess the correlation between quantitative measures of academic productivity and academic rank among academic oral and maxillofacial surgeons. This was a cross-sectional study of full-time academic oral and maxillofacial surgeons in the United States. The predictor variables were categorized as demographic (gender, medical degree, research doctorate, other advanced degree) and quantitative measures of academic productivity (total number of publications, total number of citations, maximum number of citations for a single article, I-10 index [number of publications with ≥ 10 citations], and h-index [number of publications h with ≥ h citations each]). The outcome variable was current academic rank (instructor, assistant professor, associate professor, professor, or endowed professor). Descriptive, bivariate, and multiple regression statistics were computed to evaluate associations between the predictors and academic rank. Receiver-operator characteristic curves were computed to identify thresholds for academic promotion. The sample consisted of 324 academic oral and maxillofacial surgeons, of whom 11.7% were female, 40% had medical degrees, and 8% had research doctorates. The h-index was the most strongly correlated with academic rank (ρ = 0.62, p research activity.

    The aim of this study was to evaluate whether inexpensive 3D models can be suitable to train surgical skills to dental students or oral and maxillofacial surgery residents. Furthermore, we wanted to know which of the most common filament materials, acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA), can better simulate human bone according to surgeons' subjective perceptions. Upper and lower jaw models were produced with common 3D desktop printers, ABS and PLA filament and silicon rubber for soft tissue simulation. Those models were given to 10 blinded, experienced maxillofacial surgeons to perform sinus lift and wisdom teeth extraction. Evaluation was made using a questionnaire. Because of slightly different density and filament prices, each silicon-covered model costs between 1.40-1.60 USD (ABS) and 1.80-2.00 USD (PLA) based on 2017 material costs. Ten experienced raters took part in the study. All raters deemed the models suitable for surgical education. No significant differences between ABS and PLA were found, with both having distinct advantages. The study demonstrated that 3D printing with inexpensive printing filaments is a promising method for training oral and maxillofacial surgery residents or dental students in selected surgical procedures. With a simple and cost-efficient manufacturing process, models of actual patient cases can be produced on a small scale, simulating many kinds of surgical procedures. © 2018 John Wiley & Sons A/S.

    The role of botulinum toxin as a therapeutic agent for several conditions is expanding. We sought to determine if botulinum toxin is safe and effective in treating patients with cervical dystonia and maxillofacial conditions. Our purpose was to establish a safety and efficacy profile to determine whether or not this treatment may be used prophylactically in patients undergoing dental implant therapy. We performed a systematic search of the literature to identify randomized clinical trials evaluating patients treated with botulinum toxin as an adjunct to dental implant therapy, maxillofacial conditions including temporomandibular disorders (TMD), and cervical dystonia. Four randomized controlled trials (RCTs) met our search criteria in the area of cervical dystonia and chronic facial pain. No RCTs were identified evaluating dental implant therapy. Patients with cervical dystonia exhibited significant improvements in baseline functional, pain, and global assessments compared to placebo. Adverse events were mild and transient with numbers needed to harm (NNH) ranging from 12 to 17. Patients with chronic facial pain improved significantly from baseline in terms of pain compared to placebo. Rates of adverse events were less than 1%. Botulinum toxin appears relatively safe and effective in treating cervical dystonia and chronic facial pain associated with masticatory hyperactivity. No literature exists evaluating its use in dental implantology. Randomized clinical trials are warranted to determine its safety and efficacy in dental implantology and other maxillofacial conditions such as bruxism.

    The purpose of this in vitro study was to evaluate the cytotoxicity of three maxillofacial silicone elastomers at 24, 48, and 72 h on L-929 cells and to determine the effect of accelerated aging on the cytotoxicity of these silicone elastomers. Disc-shaped test samples of maxillofacial silicone elastomers (Cosmesil, Episil, Multisil) were fabricated according to manufacturers' instructions under aseptic conditions. Samples were then divided into three groups: (1) not aged; (2) aged for 150 h with an accelerated weathering tester; and (3) aged for 300 h. Then the samples were placed in Dulbecco's Modified Eagle Medium/Ham's F12 (DMEM/F12) for 24, 48, and 72 h. After the incubation periods, cytotoxicity of the extracts to cultured fibroblasts (L-929) was measured by MTT assay. The degree of cytotoxicity of each sample was determined according to the reference value represented by the cells with a control (culture without sample). Statistical significance was determined by repeated measurement ANOVA (p test (p test materials in each group demonstrated high survival rates in MTT assay (Episil; 93.84%, Multisil; 88.30%, Cosmesil; 87.50%, respectively); however, in all groups, Episil material demonstrated significantly higher cell survival rate after each of the experimental incubation periods (p Accelerated aging for 150 and 300 h had no significant effect on the biocompatibility of maxillofacial silicone elastomers tested (p > 0.05).

    The aim of this study was to investigate the prevalence of oral and maxillofacial lesions among children from representative regions of Brazil. A retrospective descriptive study was conducted. Biopsy records comprising the period from 2000 to 2015 were obtained from the archives of three Brazilian oral pathology referral centers. A total of 32,506 biopsy specimens were analyzed, and specimens from 1,706 children aged 0-12 years were selected. Gender, age, anatomical location and histopathological diagnosis were evaluated. Descriptive statistics was carried out. Likelihood ratio tests were used to evaluate the association between the categorical variables. The level of significance was set at 0.05. The post-hoc test was used to identify the subgroups that significantly differed from one another, and the Bonferroni correction was applied. A total of 1,706 oral and maxillofacial lesions were diagnosed in pediatric patients, including 51.9% girls. Oral mucocele was the most prevalent reactive/inflammatory lesion (64%). The most commonly affected sites were the lips (34.5%) and mandible (19.9%). A significant association was observed between age and the group of lesions of the oral cavity (p oral and maxillofacial lesions were frequent and showed wide diversity, with the prevalence of mucocele. Knowledge of oral lesions is important for pediatric dentists worldwide, since it provides accurate data for the diagnosis and oral health of children.

    Full Text Available Abstract Background Little is known about the procedures used by German dental and maxillofacial surgeons treating patients suffering from chronic orofacial pain (COP. This study aimed to evaluate the ambulatory management of COP. Methods Using a standardized questionnaire we collected data of dental and maxillofacial surgeons treating patients with COP. Therapists described variables as patients' demographics, chronic pain disorders and their aetiologies, own diagnostic and treatment principles during a period of 3 months. Results Although only 13.5% of the 520 addressed therapists returned completely evaluable questionnaires, 985 patients with COP could be identified. An orofacial pain syndrome named atypical odontalgia (17.0 % was frequent. Although those patients revealed signs of chronification, pain therapists were rarely involved (12.5%. For assessing pain the use of Analogue Scales (7% or interventional diagnostics (4.6% was uncommon. Despite the fact that surgical procedures are cofactors of COP therapists preferred further surgery (41.9% and neglected the prescription of analgesics (15.7%. However, most therapists self-evaluated the efficacy of their pain management as good (69.7 %. Conclusion Often ambulatory dental and maxillofacial surgeons do not follow guidelines for COP management despite a high prevalence of severe orofacial pain syndromes.

    Surgical treatment of maxillofacial injuries has historically been associated with low reimbursements, mainly because of the high proportion of uninsured patients. The Affordable Care Act, implemented in January of 2014, aimed to reduce the number of uninsured. If the Affordable Care Act achieves this goal, surgeons may benefit from improved reimbursement rates. The authors' purpose was to evaluate the effects of the Affordable Care Act on payor distribution and surgeon reimbursements for maxillofacial trauma surgery at their institution. A review of all patients undergoing surgery for maxillofacial trauma between January of 2012 and December of 2014 was conducted. Insurance status, and amounts billed and collected by the surgeon, were recorded. Patients treated before implementation of the Affordable Care Act were compared to those treated after. Five hundred twenty-three patients were analyzed. Three hundred thirty-four underwent surgery before implementation of the Affordable Care Act, and 189 patients underwent surgery after. After implementation of the Affordable Care Act, the proportion of uninsured decreased (27.2 percent to 11.1 percent; p reimbursement rate increased from 14.3 percent to 19.8 percent (p reimbursement rate increased. These trends should be followed over a longer term to determine the full effect of the Affordable Care Act.

    Full Text Available Having standard tools for measuring pain in infants is essential. The aim of this study is to review the scale of pain in newborns under maxillofacial surgery Admitted to the surgical ward. Integrative review study of articles published from 2000 to 2015, carried out in the following databases: Scopus, PubMed, CINAHL, LILACS, Cochrane, medscape and google scholar. The sample consisted of 17 articles. MeSH headings searched included pain measurement, pain scale, newborn pain, infant pain scale, maxillofacial surgery and pain perception. 16 neonatal pain assessment tools were found. Of the 232 original articles, 17 review articles in the field of pain assessment tools in infant under maxillofacial surgery who had inclusion criteria were selected. The most studied was the Premature Infant Pain Profile (PIPP, The CRIES and the Neonatal Infant Pain Scale (NIPS. Infant pain assessment is not universally standardized. Practitioners may assess pain; however, they may not consistently use the same criteria to do so. The use of Neonatal Facial Coding System, the Neonatal Infant Pain Scale and the Premature Infant Pain Profile Can accurately show the amount of pain in newborns.

    Patients are usually left in a vulnerable state after an accident. Because of this, they long for a good encounter when they are brought to the hospital. Physical impairment and psychological morbidities are some of the complications that can occur to them. Traditionally, surgeons tend to pay little attention to a patient's emotional and psychological perspective. The aim of this study was to understand the experience of oral and maxillofacial trauma patients due to road traffic accident right from immediate after the accident till the end of definitive treatment. Phenomenological approach of qualitative study was used to explore these patients' experience. Twenty subjects involved in road traffic accidents without any cognitive impairment aged 18 and above were recruited. Purposive sampling was used to include maximal variation sample regarding age, gender, types of injury, and types of treatment received. Semi-structured and open-ended interview approach was used to obtain in-depth information. Seven themes were identified to describe the patients' response to and experience after meeting with a road traffic accident; they are unreal experiences, emotional responses, need to inform and need for information, need for assistance, their perception toward the maxillofacial injury, their experience on treatment and staff-patient interaction. This qualitative study has provided an in-depth understanding of patients experience during maxillofacial trauma and treatment, which otherwise cannot be obtained by the use of surveys and test questions.

    Hemangioma and vascular malformations in the field of oral and maxillofacial surgery is a pathology more often found in recent years in patients. The aim of this study was to evaluate the efficacy of the laser photocoagulation performed with a diode laser (Ga-Al-As) 980 nm wavelength in the treatment of vascular lesions which are located on the oral and maxillofacial areas, using color Doppler ultrasonography for evaluation of the results. We also made a comparison between laser therapy and sclerotherapy in order to establish treatment protocols and recommendations associated with this pathology. We conducted a controlled study on a group of 92 patients (38 male and 54 female patients, with an average age of 36 years) having low flow hemangioma and vascular malformations. Patients in this trial received one of the methods of treatment for vascular lesions such as hemangioma and vascular malformations: laser therapy or sclerotherapy. After laser therapy we have achieved a reduction in size of hemangioma and vascular malformations treated with such a procedure, and the aesthetic results were favorable. No reperfusion or recanalization of laser treated vascular lesions was observed after an average follow-up of 6 to 12 months. In case of sclerotherapy a reduction in the size of vascular lesions was also obtained. The 980 nm diode laser has been proved to be an effective tool in the treatment of hemangioma and vascular malformations in oral and maxillofacial area. Laser therapy in the treatment of vascular lesions was more effective than the sclerotherapy procedure.

    The incidence of sport-related concussion (SRC) in high school football is well documented. However, limited prospective data are available regarding how player characteristics and protective equipment affect the incidence of SRC. To determine whether the type of protective equipment (helmet and mouth guard) and player characteristics affect the incidence of SRC in high school football players. Cohort study; Level of evidence, 2. Certified athletic trainers (ATs) at each high school recorded the type of helmet worn (brand, model, purchase year, and recondition status) by each player as well as information regarding players' demographics, type of mouth guard used, and history of SRC. The ATs also recorded the incidence and days lost from participation for each SRC. Incidence of SRC was compared for various helmets, type of mouth guard, history of SRC, and player demographics. A total of 2081 players (grades 9-12) enrolled during the 2012 and/or 2013 football seasons (2287 player-seasons) and participated in 134,437 football (practice or competition) exposures. Of these players, 206 (9%) sustained a total of 211 SRCs (1.56/1000 exposures). There was no difference in the incidence of SRC (number of helmets, % SRC [95% CI]) for players wearing Riddell (1171, 9.1% [7.6%-11.0%]), Schutt (680, 8.7% [6.7%-11.1%]), or Xenith (436, 9.2% [6.7%-12.4%]) helmets. Helmet age and recondition status did not affect the incidence of SRC. The rate of SRC (hazard ratio [HR]) was higher in players who wore a custom mouth guard (HR = 1.69 [95% CI, 1.20-2.37], P football players. Players who had sustained an SRC within the previous 12 months were more likely to sustain an SRC than were players without a history of SRC. Sports medicine providers who work with high school football players need to realize that factors other than the type of protective equipment worn affect the risk of SRC in high school players. © 2014 The Author(s).

    To provide epidemiological data and related costs for sport-related injuries of five sporting codes (cricket, netball, rugby league, rugby union and football) in New Zealand for moderate-to-serious and serious injury claims. A retrospective analytical review using detailed descriptive epidemiological data obtained from the Accident Compensation Corporation (ACC) for 2012-2016. Over the 5 years of study data, rugby union recorded the most moderate-to-serious injury entitlement claims (25 226) and costs (New Zealand dollars (NZD$)267 359 440 (£139 084 749)) resulting in the highest mean cost (NZD$10 484 (£5454)) per moderate-to-serious injury entitlement claim. Rugby union recorded more serious injury entitlement claims (n=454) than cricket (t (4) =-66.6; P<0.0001); netball (t (4) =-45.1; P<0.0001); rugby league (t (4) =-61.4; P<0.0001) and football (t (4) =66.6; P<0.0001) for 2012-2016. There was a twofold increase in the number of female moderate-to-serious injury entitlement claims for football (RR 2.6 (95%CI 2.2 to 2.9); P<0.0001) compared with cricket, and a threefold increase when compared with rugby union (risk ratio (RR) 3.1 (95%CI 2.9 to 3.3); P<0.0001). Moderate-to-serious concussion claims increased between 2012 and 2016 for netball (RR 3.7 (95%CI 1.9 to 7.1); P<0.0001), rugby union (RR 2.0 (95% CI 1.6 to 2.4); P<0.0001) and football (RR 2.3 (95%CI 1.6 to 3.2); P<0.0001). Nearly a quarter of moderate-to-serious entitlement claims (23%) and costs (24%) were to participants aged 35 years or older. Rugby union and rugby league have the highest total number and costs associated with injury. Accurate sport exposure data are needed to enable injury risk calculations. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

    Fractures of the proximal femur include fractures of the head, neck, intertrochanteric, and subtrochanteric regions. Head fractures commonly accompany dislocations. Neck fractures and intertrochanteric fractures occur with greatest frequency in elderly patients with a low bone mineral density and are produced by low-energy mechanisms. Subtrochanteric fractures occur in a predominantly strong cortical osseous region which is exposed to large compressive stresses. Implants used to address these fractures must be able to accommodate significant loads while the fractures consolidate. Complications secondary to these injuries produce significant morbidity and include infection, nonunion, malunion, decubitus ulcers, fat emboli, deep venous thrombosis, pulmonary embolus, pneumonia, myocardial infarction, stroke, and death.

    Perioperative antibiotic prophylaxis in patients undergoing surgery for maxillofacial fractures is standard practice. However, the use of postoperative antibiotic prophylaxis remains controversial. This systematic review and meta-analysis sought to evaluate the effect of postoperative antibiotic therapy on the incidence of surgical site infection (SSI) in patients with maxillofacial fractures. MEDLINE, Embase, and the Cochrane Library were searched from inception through October 2017. Randomized controlled trials (RCTs) and cohort studies evaluating the efficacy of pre-, peri-, and postoperative antibiotic prophylaxis in preventing SSI in maxillofacial fractures were included. Data were extracted from studies using a standardized data collection form, with two reviewers independently performing extraction and quality assessment for each study. Risk ratios (RRs) for SSI were pooled using a random-effects model. Among 2,150 potentially eligible citations, 13 studies met inclusion criteria and provided data to be included in a meta-analysis. The addition of postoperative antibiotic prophylaxis to a standard preoperative and/or perioperative antibiotic regimen showed no significant difference in the risk of SSI (RR = 1.11 [95% CI: 0.86-1.44], P > .1). There were also no differences in the risk of SSI when restricting the analysis to mandibular fractures (eight studies, RR = 1.22 [95% CI: 0.92-1.62]) or open surgical techniques (eight studies, RR = 1.02 [95% CI: 0.62-1.67]). A sensitivity analysis did not find any significant differences in risk when restricting to RCTs (seven trials, RR = 1.00 [95% CI: 0.61-1.67]) or cohort studies (six studies, RR = 1.21 [95% CI: 0.89-1.63]). Our findings, along with the available evidence, does not support the routine use of postoperative antibiotic prophylaxis in patients with maxillofacial fractures. Avoiding the unnecessary use of antibiotic therapy in the postoperative period could have important

    Clavicle fractures in children occur twice as often as in adults. During a child's growth period they account for 10-15% of all fractures sustained. The questions which should be asked are how these fractures are sustained and under which circumstances are the children injured. In the study 256 children with clavicle fractures treated during the period 2008-2013 were analyzed. The underlying cause and place of injuries were classified using the ICD-10 classification system, using environmental causes of injury. The circumstances were in each case accidental injury. Environmental causes were traffic accidents (V01-V99) or mishaps/accidents (W00-X59). Fracture injuries were caused in traffic accidents in 24 (9.4%), and in mishaps/accidents in 232 (90.6%) children. Of the injuries caused by mishaps/accidents, in 204 children these were caused by falls (W00-W19). In 123 of them the injuries were caused by falls from a ground level, and in 81 were from a greater height. Direct blow injuries, caused by another person or a blunt instrument, weere the causes of fractures seen in 28 children. Place of fracture sustainment was dominantly at home. This was followed by injuries sustained outside in recreational areas, while least were suffered at school or kindergarden facilities. Bicycle riding was the cause of clavicle fractures in 48 children, which was 18.7% of all fractures seen. Sports related injuries and fractures were seen in 47 (18.4%) out of 256 children: 30 in football, 10 in defensive sports (wrestling, judo, karate), three in hockey, while basketball and gymnastics accounted for two each. Preschool children were injured more often while in the care of their parents while school aged children were adaquately protected, but in after-school activities they were often injured. The most common injuries after school were those suffered in traffic accidents and recreational sports activities. In the adolescent period, the most common injuries seen were again those in

    Mandibular fracture is the most common bone fracture of maxillo-facial trauma. Up to now the main method for examination of the mandible is radiography. The aim of the issue is to present an algorithm of imaging modalities for investigation of patients in cases of mandibular trauma. It consists of series of X ray techniques and views of the facial skull named mandibulo-facial. This standardizes mandibulo-facial series includes exactly determined four projections done by conventional X ray techniques: posterior-anterior view of skull (PA or AP), oblique view of the left mandible; oblique view of the right mandible; occipito-mental view. Using these four planned radiograms is obligatory for each mandibular trauma. Panoramic X-ray is obligatory in cases of apparatus availability; this abolish only oblique views (left and right). Occipito-mental view of the skull gives anatomically better the coronoid process of the mandible, the zygoma complex, the orbital edges and maxillar sinus than Waters projection. So mandibulo-facial series of four planned radiograms is not only for diagnostic of mandibular fractures, but as a screening of mandibulo-facial trauma too. Thus using algorithm of imaging modalities in cases of mandibular fracture leads to optimization of diagnostic process in patients with mandibular trauma. (author)

    Three-dimensional (3-D) printing has been identified as an innovative manufacturing technology of functional parts. The 3-D model was produced based on CT-Scan using Osyrix software, where automatic segmentation was performed and convert into STL format. This STL format was then ready to be produced physically, layer-by-layer to create 3-D model.

    Men who receive bone-targeted therapy for metastatic prostate cancer are at increased risk of osteonecrosis of the jaw (ONJ). Development of ONJ has been associated with the administration of bone-targeted therapies in association with other risk factors. ONJ can be distressing for a patient because it can cause pain, risk of jaw fracture, body image disturbance, difficultly eating, and difficulty maintaining good oral hygiene. The aim of this article is to report results of an audit of prior assessment by oral and maxillofacial surgeons (OMFS) before initiation of bone-targeted therapies and whether it may reduce the risk of ONJ in patients receiving bone-targeted therapies for advanced cancers.

    Small nonossifying fibromas (ie, fibrocortical defects) are incidental findings commonly seen on radiographs of young patients evaluated for extremity pain or sport-related trauma. Although pathological fractures have been reported in larger lesions, the subcentimeter, intracortical defects are not generally thought to predispose to pathological fractures. The authors report on 2 young athletes who presented with knee pain after initiating conditioning exercise programs (cross-training). Both were diagnosed with transverse metaphyseal stress fractures involving fibrous cortical defects of the distal femur. Initial radiographs were interpreted without evidence of fractures. However, subsequent magnetic resonance imaging was informative, suggesting that magnetic resonance imaging may have value in identifying potential stress reactions in young athletes. In addition, subsequent plain radiographs of both patients showed subperiosteal new bone formation in these nondisplaced fractures, suggesting that serial radiographs and close clinical follow-up are warranted for patients with persistent symptoms. The authors propose that, in the appropriate clinical setting, the presence of a small nonossifying fibroma may be a clinical indication that further evaluation is needed when plain radiographs show normal findings, as the defect could be an unrecognized area of fracture initiation.

    The use of titanium mesh in communited mandibular fractures has been substantially documented. However, the use of stainless steel mesh for routine fixation in mandibular fractures has not been widely reported. The aim of the present study was to evaluate the efficacy of stainless steel mesh for routine osteosynthesis of mandibular fractures. A total of 252 patients who had been diagnosed with 287 single or multiple mandibular fractures at Guru Nanak Institute of Dental Science and Research from 2002 to 2009 were selected for the present study. Those with condylar fractures and other maxillofacial injuries were excluded from the study. The patients were evaluated preoperatively, intraoperatively, and postoperatively at 1 day, 6 weeks, and 3 and 6 months. The local complications, occlusion (for static function), and chewing (for dynamic function) were evaluated postoperatively. The intraoperative time taken for implant fixation (from site exposure to fixation of the last screw) was 32 minutes. Of the 252 patients, 40 (15.8%) had local complications and 24 patients required implant removal. Of the 252 patients, 82% had bilaterally satisfactory occlusion according to the surgeon at 6 months postoperatively. Discomfort in chewing unilaterally or bilaterally was reported by 17% of the patients. The results of our study have shown that stainless steel mesh has acceptable complication rates and the ability to maintain occlusion and chewing postoperatively compared with the present standards of care of mandibular fractures using miniplates. The lower cost and versatile placement of screws were the principal advantages. However, placement near the mental foramen with an extraoral approach for certain sites is the primary disadvantage.

    Fractures are a common complication of osteoporosis. Although osteoporosis is defined by bone mineral density at the femoral neck, other sites and validated techniques can be used for fracture prediction. Several clinical risk factors contribute to fracture risk independently of BMD. These include age, prior fragility fracture, smoking, excess alcohol, family history of hip fracture, rheumatoid arthritis and the use of oral glucocorticoids. These risk factors in conjunction with BMD can be integrated to provide estimates of fracture probability using the FRAX tool. Fracture probability rather than BMD alone can be used to fashion strategies for the assessment and treatment of osteoporosis.

    Unilateral fracture of the condylar neck in immature subjects might lead to mandible asymmetry and condyle remodelling. A rat model was used to investigate mandibular deviation and condylar remodelling associated with condyle fracture. 72 4-week-old male rats were randomly divided into three groups: an experimental group (unilateral transverse condylar fracture induced surgically), a sham operation group (surgical exposure but no fracture), and a non-operative control group (no operation). The rats were killed at intervals up to 9weeks after surgery, and outcomes were assessed using various measures of mandible deviation, histological and X-ray observation, and immunohistochemical measures of expression levels of connective tissue growth factor (CTGF) and type II collagen (Col II). The fracture led to the degeneration of mandibular size, associated with atrophy of fractured condylar process. Progressive remodelling of cartilage and increasing expression levels of CTGF and Col II were found. The authors conclude that condylar fracture can lead to asymmetries in mandible and condyle remodelling and expression of CTGF and Col II in condylar cartilage on both the ipsilateral and the contralateral sides.

    In the treatment of mandibular condyle fracture, conservative treatment using closed reduction or surgical treatment using open reduction can be used. Management of mandibular condylar fractures remains a source of ongoing controversy in oral and maxillofacial trauma. For each type of condylar fracture,the treatment method must be chosen taking into consideration the presence of teeth, fracture height, patient'sadaptation, patient's masticatory system, disturbance of occlusal function, and deviation of the mandible. In the past, closed reduction with concomitant active physical therapy conducted after intermaxillary fixation during the recovery period had been mainly used, but in recent years, open treatment of condylar fractures with rigid internal fixation has become more common. The objective of this review was to evaluate the main variables that determine the choice of an open or closed method for treatment of condylar fractures, identifying their indications, advantages, and disadvantages, and to appraise the current evidence regarding the effectiveness of interventions that are used in the management of fractures of the mandibular condyle.

    Injuries due to traffic accidents are frequent in childhood, and they have high mortality and morbidity. Laryngeal injury due to a traffic accident is a rare pathology and might be missed if not suspected. Here we present a laryngeal fracture in a child after a blunt chest trauma during a traffic accident that presented with pneumomediastinum and pneumothorax. A 14-year-old girl was referred for pneumomediastinum. Her physical examination was normal except subcutaneous emphysema, edema and tenderness in the cervical area, hoarseness, facial and extremity abrasions and ecchymoses. Chest tomography revealed pneumothorax and pneumomediastinum, and cranial tomography revealed maxillofacial fractures. Upper airway damage was suspected, flexible endoscopy revealed right vocal cord paralysis and cervical tomography revealed thyroid cartilage fracture. The fracture was repaired and tracheotomy was performed. She was discharged on postoperative day 6. Facial fractures were repaired in another center. Tracheotomy was removed on postoperative day 20. Her hoarseness, although decreased, still persists. Pneumomediastinum is a rare result of a laryngeal fracture and if not suspected, the fracture can easily be missed. It should be kept in mind after blunt cervical trauma with pneumomediastinum and/or pneumothorax. Direct endoscopy and cervical tomography may be necessary for the differential diagnosis.

    Previous retrospective analyses prove that impacted mandibular third molars (M3s) increase the risk of angle fractures and decrease the risk of concomitant fractures to the condyle. A retrospective cohort was designed for patients reported to the Department of Oral and Maxillofacial Surgery from January 2011 till June 2013. The study variables are presence or absence of third molar, if it is present, their position, classified using the Pell and Gregory system; angulation, classified using Shiller's method. The outcome variables were angle and condyle fractures. Hospital records and panoramic radiographs were used to determine and classify these variables. The study sample comprised of 118 mandibular angle and condyle fractures in 110 patients. Database was constructed and analysed using SPSS version 10.0. This present retrospective study concluded that the presence of impacted third molar predisposes the angle to fracture and reduces the risk of a concomitant condylar fracture. However absence of impacted third molar increases the risk of condylar fracture. The highest incidence of angle fracture was observed in position A impacted mandibular third molars. And there is no significant relationship, concerning ramus position and angulation of impacted mandibular third molars with the angle fracture.

    Full Text Available Complicated crown-root fracture of maxillary central and lateral incisors is common in case of severe trauma or sports-related injury. It happens because of their anterior positioning in oral cavity and protrusive eruptive pattern. On their first dental visit, these patients are in pain and need emergency care. Because of impaired function, esthetics, and phonetics, such patients are quite apprehensive during their emergency visit. Successful pain management with immediate restoration of function, esthetics and phonetics should be the prime objective while handling such cases. This paper describes immediate treatment of oblique crown root fracture of maxillary right lateral incisor with reattachment procedure using light transmitting fiber post. After two and half years, the reattached fragment still has satisfying esthetics and excellent function.

    While virtual learning environments (VLE) can be used in medical education as stand-alone educational interventions, they can also be used in preparation for traditional "face-to-face" training sessions as part of a "flipped classroom" model. We sought to evaluate the introduction of this model in a single module on maxillofacial radiology from a course on trauma skills. Course delegates were randomised into two groups: one was given access to an e-learning resource (test group) and the other attended a traditional didactic lecture (control group). Knowledge and confidence were assessed before and after the course with a 20-question single-best-answer paper and a 10-situation 100mm visual analogue scale (VAS) paper, respectively. All participants were then given free access to the VLE for 30days and were invited to take part in an e-survey. Neither group showed improvements in the single-best-answer scores, but both groups showed comparable improvements in VAS (control: median (range) values improved from 40.8 (17.7-82.5) mm to 62.8 (35.3-88.7) mm, p=0.001; test group: from 47.7 (10.9-58.1) mm to 60.5 (32.4-75.6) mm, p=0.005). Half of the respondents stated that they preferred the "flipped classroom" approach, and 22/22 stated that they would be "likely" or "very likely" to use an e-learning resource with expanded content. The "flipped classroom" approach was well received and there were comparable improvements in confidence. As maxillofacial radiology lends itself to online instruction with its reliance on the recognition of patterns, and problem-based approach to learning, a piloted e-learning resource could be developed in this area.

    Yearly surveys among the undergraduate students in oral and maxillofacial surgery at Karolinska Institutet have conveyed a wish for increased clinical training, and in particular, in surgical removal of mandibular third molars. Due to lack of resources, this kind of clinical supervision has so far not been possible to implement. One possible solution to this problem might be to introduce simulation into the curriculum. The purpose of this study was to investigate undergraduate students' perception of two different simulation methods for practicing clinical reasoning skills and technical skills in oral and maxillofacial surgery. Forty-seven students participating in the oral and maxillofacial surgery course at Karolinska Institutet during their final year were included. Three different oral surgery patient cases were created in a Virtual Patient (VP) Simulation system (Web-SP) and used for training clinical reasoning. A mandibular third molar surgery simulator with tactile feedback, providing hands on training in the bone removal and tooth sectioning in third molar surgery, was also tested. A seminar was performed using the combination of these two simulators where students' perception of the two different simulation methods was assessed by means of a questionnaire. The response rate was 91.5% (43/47). The students were positive to the VP cases, although they rated their possible improvement of clinical reasoning skills as moderate. The students' perception of improved technical skills after training in the mandibular third molar surgery simulator was rated high. The majority of the students agreed that both simulation techniques should be included in the curriculum and strongly agreed that it was a good idea to use the two simulators in concert. The importance of feedback from the senior experts during simulator training was emphasised. The two tested simulation methods were well accepted and most students agreed that the future curriculum would benefit from

    Post graduate learning and assessment is an important responsibility of an academic oral and maxillofacial surgeon. The current method of assessment for post graduate training include formative evaluation in the form of seminars, case presentations, log books and infrequently conducted end of year theory exams. End of the course theory and practical examination is a summative evaluation which awards the degree to the student based on grades obtained. Oral and maxillofacial surgery is mainly a skill based specialty and deliberate practice enhances skill. But the traditional system of assessment of post graduates emphasizes their performance on the summative exam which fails to evaluate the integral picture of the student throughout the course. Emphasis on competency and holistic growth of the post graduate student during training in recent years has lead to research and evaluation of assessment methods to quantify students' progress during training. Portfolio method of assessment has been proposed as a potentially functional method for post graduate evaluation. It is defined as a collection of papers and other forms of evidence that learning has taken place. It allows the collation and integration of evidence on competence and performance from different sources to gain a comprehensive picture of everyday practice. The benefits of portfolio assessment in health professions education are twofold: it's potential to assess performance and its potential to assess outcomes, such as attitudes and professionalism that are difficult to assess using traditional instruments. This paper is an endeavor for the development of portfolio method of assessment for post graduate student in oral and maxillofacial surgery.

    Full Text Available Background. Victims of motor vehicle accidents may suffer multiple lesions, including maxillofacial injuries. The aim of this study was to evaluate the prevalence and factors associated with head, facial, and maxillofacial injuries in child and adolescent victims of automobile accidents. A cross-sectional study was carried out with analysis of forensic medical reports from the Legal Medical Institute of Campina Grande, Brazil, between January 2008 and December 2011. Descriptive and inferential statistical analysis was conducted using the chi-square test (α = 0.05. From 1613 medical reports analyzed, the sample is composed 232 (14.4% reports referring to child and adolescent victims of automobile accidents aged 0–19 years of both sexes. Victims were mostly adolescents aged from 15 to 19 years (64.2%, males (73.7%, and motorcyclists (51.3%. More than half of the victims had single lesions (54.3% located in the head (20.7% and face (21.6%. Head injuries occurred more frequently in children aged 0–4 years (53.8%, PR = 5.065, 95% CI = 1.617–5.870 and pedestrians (30.4%, PR = 2.039, 95% CI = 1.024–4.061, while facial and maxillofacial injuries occurred in higher proportion among females (31.1%, PR = 0.489, 95% CI = 0.251–0.954. Our findings suggest that accidents involving motorcyclists are the most prevalent, affecting male adolescents aged from 15 to 19 years, resulting in a high frequency of injuries in the head and face regions.

Retrospectively, the clinical records of patients with a primary diagnosis of DLBCL of the oral cavity and maxillofacial region treated at the A.C. Camargo Hospital for Cancer, São Paulo, Brazil, between January 1980 and December 2005 were evaluated to determine (A overall survival (OS at 2 and 5 years and the individual survival percentage for each possible prognostic factor by means of the actuarial technique (also known as mortality tables, and the Kaplan Meier product limit method (which provided the survival value curves for each possible prognostic factor; (B prognostic factors subject to univariate evaluation with the log-rank test (also known as Mantel-Cox, and multivariate analysis with Cox's regression model (all the variables together. The data were considered significant at p ≤ 0.05. From 1980 to 2005, 3513 new cases of lymphomas were treated, of which 151 (4.3% occurred in the oral cavity and maxillofacial region. Of these 151 lesions, 48 were diffuse large B-cell lymphoma, with 64% for OS at 2 years and 45% for OS at 5 years. Of the variables studied as possible prognostic factors, multivariate analysis found the following variables have statistically significant values: age (p = 0.042, clinical stage (p = 0.007 and performance status (p = 0.031. These data suggest that patients have a higher risk of mortality if they are older, at a later clinical stage, and have a higher performance status.

    This study was designed to evaluate clinical photographs published in the Journal of Oral and Maxillofacial Surgery (JOMS) and understand the current status of oral and maxillofacial surgery. A total of 1,317 photographs from the JOMS Volume 69 were assessed. These photographs were scored from 1 to 10 for the following parameters: sharpness; depth of field; exposure; composition; color or grayscale; background; position; distortion; label consistency; and white balance. Then, the distributions of scores were analyzed. Each score was compared with the average score. The effects of different subjects; emergency or nonemergency situations; and intraoperative, preoperative, or postoperative conditions on the quality of photographs were analyzed by conducting a nonparametric Kruskal-Wallis test. The total score of each photograph showed a left-skewed distribution, varying from 3 to 10, with an average score of 6.82. Four parameters, including sharpness, depth of field, exposure, and white balance, scored less than the average score. Photographs with an intraoral subject yielded the lowest score, with a significant difference (P photographs taken during a nonemergency situation was significantly higher than that during an emergency situation (6.84 vs 6.03; P Photographs of an intraoperative condition yielded a score significantly lower than those of pre- and postoperative conditions (6.53 vs 7.11 and 6.75, respectively; P photographs (148 of 325) displayed uncovered eyes and 57.1% of specimens (40 of 70) did not appear with a plotting scale. Sharpness, depth of field, exposure, and white balance should be considered to a greater extent than the other parameters when oral and maxillofacial photographs are taken, particularly for intraoral conditions, emergency situations, and intraoperative conditions. Enhanced parameters and protection of a patient's identity may significantly improve the average level of photographic quality. Crown Copyright © 2014. Published by

    Full Text Available Context: Maxillofacial prostheses need frequent refabrication due to degradation of color and deterioration of physical properties of the elastomer. Aims: This study attempted to evaluate the change in color stability, Shore A hardness, and surface roughness of two maxillofacial silicones, A-2186 and Cosmesil M511, when submitted to chemical disinfection and accelerated aging. Settings and Design: This was a comparative in vitro study. Subjects and Methods: The materials included two silicone elastomers – A-2186 and Cosmesil M511 (Factor II Incorporated – functional intrinsic red pigment and three disinfectants – Fittydent tablet, chlorhexidine gluconate 4%, and neutral soap. The specimens in each group of elastomer were evaluated initially for color, hardness, and surface roughness, which were further divided into subgroups and subjected to disinfection and accelerated aging. The evaluation of color was performed with the help of an ultraviolet reflectance spectrophotometer. Shore A hardness was evaluated using a durometer and surface roughness, with a digital roughness tester followed by scanning electron microscopy analysis. Statistical Analysis Used: Analysis of variance and Tukey's multiple comparison test were used for statistical analysis. Results: Accelerated aging caused a significant decrease in color, increase in Shore A hardness, and variation in surface roughness in both silicone elastomer groups. Chemical disinfection presented significant changes in color and surface roughness whereas no significant effect on Shore hardness, irrespective of the disinfectant used. Conclusions: The maxillofacial silicone elastomers presented deterioration in color, hardening, and significant variations in surface roughness when subjected to chemical disinfection and accelerated aging, which provides a valid baseline for future research.

    Full Text Available Objectives: The purpose of the study was to establish the role of ultrasonography in determining the involvement of specific fascial spaces in maxillofacial region and the stage of infection, in indicating the appropriate time for surgical intervention and to compare clinical and ultrasonographic findings.Material and Methods: Twenty five patients with fascial space infection in maxillofacial region were subjected to ultrasonographic examination following a detailed clinical and radiological examination. Ultrasonography guided needle aspiration was performed. Based on the findings, patients diagnosed with abscess were subjected to incision and drainage and those with cellulitis were subjected to medical line of treatment.Results: More than one fascial space was involved in all patients. On clinical examination 64 spaces were involved, of them 34 spaces had abscess formation and 30 spaces were in the stage of cellulitis. On ultrasonography examination, 28 spaces were reported to have abscess formation and 36 spaces were diagnosed to be in the stage of cellulitis. On comparative analysis of both clinical and ultrasonographic findings, ultrasonography was found to be sensitive in 65% of the cases and having specificity of 80%. It was registered statistically significant (P < 0.001 agreement between these two methods of assessment (kappa index = 0.814.Conclusions: Ultrasonography is a quick, widely available, relatively inexpensive, and painless procedure and can be repeated as often as necessary without risk to the patient. Thus ultrasonography is a valuable diagnostic aid to the oral and maxillofacial surgeon for early and accurate diagnosis of fascial space infection, their appropriate treatment and to limit their further spread.

    Full Text Available Electronic cigarettes (also known as e-cigarettes or e-cigs are becoming a popular method of recreational nicotine use over recent years. The growth of new brands and devices has been outpacing the FDA’s ability to regulate them. As a result, some of these devices fail without warning, most likely from malfunction of the lithium-ion batteries that are in close proximity to volatile compounds within the device. Failures have occurred during both use and storage of the devices or their components. The subsequent injuries from several of these events, including full thickness burns requiring grafting and blast injuries, have been observed at Arrowhead Regional Medical Center, a regional trauma and burn center in southern California. One severe case resulted in several maxillofacial fractures, blurred vision, and pneumocephalus after a device failed catastrophically during use. The patient required close monitoring with serial imaging by neurosurgery in the intensive care unit and multiple procedures by oral maxillofacial surgery to reconstruct his facial bones and soft tissue. Ultimately, the patient recovered with minimal permanent damage, but the potential for further injury or even death was apparent. Cases such as this one are becoming more frequent. It is important to increase awareness of this growing problem for both medical professionals and the general public in order to curb this concerning new trend.

    We present an assessment of the dental and maxillofacial pathology in a medieval population in southwestern France. One hundred and ninety eight mandibles and 29 craniofacial complexes were analysed. Dental and periodontal infectious pathology predominated. Third molar agenesia was quite frequent, concerning 25% of the mandibles. Third molar eruption was almost constant and in a normal position. Condylar process degeneration concerned 6% of the population. Three cases of traumatic pathology were observed, one case of long mandible was noted, and two cases of hypertrophic inferior alveolar process. Dento-mandibular maladjustment was uncommon. No unwedging of the maxillo-mandibular bone basis was observed.

    Dose reduction on CT scans for surgical planning and postoperative evaluation of midface and orbital fractures is an important concern. The purpose of this study was to evaluate the variability of various low-dose and iterative reconstruction techniques on the visualization of orbital soft tissues. Contrast-to-noise ratios of the optic nerve and inferior rectus muscle and subjective scores of a human cadaver were calculated from CT with a reference dose protocol (CT dose index volume = 36.69 mGy) and a subsequent series of low-dose protocols (LDPs I-4: CT dose index volume = 4.18, 2.64, 0.99, and 0.53 mGy) with filtered back-projection (FBP) and adaptive statistical iterative reconstruction (ASIR)-50, ASIR-100, and model-based iterative reconstruction. The Dunn Multiple Comparison Test was used to compare each combination of protocols (α = .05). Compared with the reference dose protocol with FBP, the following statistically significant differences in contrast-to-noise ratios were shown (all, P ≤ .012) for the following: 1) optic nerve: LDP-I with FBP; LDP-II with FBP and ASIR-50; LDP-III with FBP, ASIR-50, and ASIR-100; and LDP-IV with FBP, ASIR-50, and ASIR-100; and 2) inferior rectus muscle: LDP-II with FBP, LDP-III with FBP and ASIR-50, and LDP-IV with FBP, ASIR-50, and ASIR-100. Model-based iterative reconstruction showed the best contrast-to-noise ratio in all images and provided similar subjective scores for LDP-II. ASIR-50 had no remarkable effect, and ASIR-100, a small effect on subjective scores. Compared with a reference dose protocol with FBP, model-based iterative reconstruction may show similar diagnostic visibility of orbital soft tissues at a CT dose index volume of 2.64 mGy. Low-dose technology and iterative reconstruction technology may redefine current reference dose levels in maxillofacial CT. © 2017 by American Journal of Neuroradiology.

    Maxillofacial injuries can result in psychological derangement, leading to post-traumatic stress disorder (PTSD), which is characterized by continual re-experiencing of any traumatic event in addition to numerous systemic complications. The objective of this study was to assess the incidence and severity of "PTSD-related depression" in patients with maxillofacial injuries and to identify the risk factors involved. This prospective study involved 88 patients with maxillofacial trauma who had only cosmetic deficits (group A), only functional deficits (group B), or cosmetic and functional deficits (group C). The psychological status of all patients was assessed before and after surgery using Zung's Self-Rating Depression Scale. Remission time also was analyzed. Data were analyzed with SPSS 22.0 using parametric methods. Comparison of mean values among groups was performed using 1-way analysis of variance followed by Tukey honest significance difference post hoc tests for multiple pairwise comparisons. To compare proportions, the χ 2 test was applied. The number of patients in groups A, B, and C was 11, 34 and 43, respectively. In the immediate post-trauma stage, all patients in group A showed severe depression; the percentages of patients with severe depression in groups B and C were 8.8 and 81.4%, respectively, which was statistically relevant. Depression scores of patients of all groups decreased gradually in the postsurgical phase. Patients with cosmetic defects consistently recorded higher depression scores at all intervals. The time taken for recovery from depression (remission time) was shorter for patients with only functional deficits (group B). Patients with maxillofacial injuries are prone to PTSD-related depression from functional and cosmetic deficits. The objectives of trauma management must be aimed at restoring pre-trauma form and function of the maxillofacial skeleton and the patient's psychological status.

    We assessed the frequency and types of ankle fractures that frequently occur during parachute landings of special operation unit personnel and analyzed the causes. Fifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute landings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications. Follow-up surveys were performed with respect to the American Orthopedic Foot and Ankle Society ankle-hindfoot score, patient satisfaction, and return to preinjury activity. The patients were all males with a mean age of 23.6 years. There were 28 right and 28 left ankle fractures. Twenty-two patients had simple fractures and 34 patients had comminuted fractures. The average number of injury and fractures sites per person was 2.07 (116 injuries including a syndesmosis injury and a deltoid injury) and 1.75 (98 fracture sites), respectively. Twenty-three cases (41.07%) were accompanied by posterior malleolar fractures. Fifty-five patients underwent surgery; of these, 30 had plate internal fixations. Weber type A, B, and C fractures were found in 4, 38, and 14 cases, respectively. Based on the Lauge-Hansen classification, supination-external rotation injuries were found in 20 cases, supination-adduction injuries in 22 cases, pronation-external rotation injuries in 11 cases, tibiofibular fractures in 2 cases, and simple medial malleolar fractures in 2 cases. The mean follow-up period was 23.8 months, and the average follow-up American Orthopedic Foot and Ankle Society ankle-hindfoot score was 85.42. Forty-five patients (80.36%) reported excellent or good satisfaction with the outcome. Posterior malleolar fractures occurred in 41.07% of ankle fractures sustained in parachute landings. Because most of the ankle fractures in parachute injuries were compound fractures, most cases had to

    Maxillofacial traumas with long-barreled guns may sometimes cause catastrophic results by means of smashing in facial structures. In these patients, reconstruction strategies of both fragmented/lost soft and hard tissues still remain controversial. In their clinic, the authors treated 5 patients with severely injured face after failed suicide attempt between 2008 and 2013. In this study, the authors aimed to present their clinical experiences on these severely injured maxillofacial gunshot traumas and offer a treatment algorithm to gain a result as possible as satisfactory in terms of functionality and appearance.

    Surgical correction is central to current team-approached cleft treatment. Cleft surgeons are always concerned about the impact of their surgical maneuver on the growth of the maxilla. Hypoplastic maxilla, concaved mid-face and deformed dental arch have constantly been reported after cleft treatments. It is very hard to completely circumvent these postoperative complications by current surgical protocols. In this paper, we discussed the factors that inhibit the maxillofacial growth on cleft patients. These factors included pre-surgical intervention, the timing of cleft palate and alveolae repair, surgical design and treatment protocol. Also, we made a review about the influence on the maxillary growth in un-operated cleft patients. On the basis of previous researches, we can conclude that most of scholars express identity of views in these aspects: early palatoplasty lead to maxilla growth inhibition in all dimensions; secondary alveolar bone graft had no influence on maxilla sagittal growth; cleft lip repair inhibited maxilla sagittal length in patients with cleft lip and palate; Veau's pushback palatoplasty and Langenbeck's palatoplasty with relaxing incisions were most detrimental to growth; Furlow palatoplasty showed little detrimental effect on maxilla growth; timing of hard palate closure, instead of the sequence of hard or soft palate repair, determined the postoperative growth. Still, scholars hold controversial viewpoints in some issues, for example, un-operated clefts have normal growth potential or not, pre-surgical intervention and pharyngoplasty inhibited maxillofacial growth or not.

    This study explored how residents who intend to enter private practice versus academic careers differ in their background and educational characteristics, engagement in different professional activities, professional values, and satisfaction. Survey data were collected from 257 residents in oral and maxillofacial surgery programs in the United States. The responses of the respondents who planned a career in private practice (65%) and who considered academia (35%) were compared with χ(2) and independent-sample t tests. Residents who considered academia were more likely to be women (29% vs 8%; P career compared with residents interested in private practice. Future clinicians placed a higher value on having manageable hours and more time performing outpatient procedures than future educators. These findings showed, first, that the characteristics at the beginning of residency programs that are likely to indicate an increased interest in academic careers are being a woman, from a non-European American background, and having an interest in research. Second, once residents are admitted, different types of surgeries and different types of professional activities tend to appeal to residents who want to practice in private practice settings versus work in academia. Third, residents interested in academia have a relatively lower level of satisfaction compared with residents interested in practicing outside of academia.

    Clinical coding has important financial implications, and discrepancies in the assigned codes can directly affect the funding of a department and hospital. Over the last few years, numerous oversights have been noticed in the coding of oral and maxillofacial (OMF) procedures. To establish the accuracy and completeness of coding, we retrospectively analysed the records of patients during two time periods: March to May 2009 (324 patients), and January to March 2014 (200 patients). Two investigators independently collected and analysed the data to ensure accuracy and remove bias. A large proportion of operations were not assigned all the relevant codes, and only 32% - 33% were correct in both cycles. To our knowledge, this is the first reported audit of clinical coding in OMFS, and it highlights serious shortcomings that have substantial financial implications. Better input by the surgical team and improved communication between the surgical and coding departments will improve accuracy.

    The eruption of the first and second permanent molar teeth may influence the size of the retromolar space. In this study we evaluated the adequacy of the retromolar space for retromolar intubation and any effect of eruption of the first and second permanent molar teeth on this space in children. Children 3-15 yr of age, undergoing surgery other than facial surgery were included for evaluation of the retromolar space. After standard oral tracheal intubation, the endotracheal tube was shifted to the retromolar space and the mandible was slowly closed to achieve centric occlusion. At the same time, any increase in airway resistance or decrease in oxygen saturation was noted. In the second part of the study, the feasibility of retromolar intubation in pediatric patients undergoing maxillofacial surgery with intraoperative maxillomandibular fixation was assessed. There was enough space for endotracheal tube placement in the retromolar region. The eruption of the first and second permanent molar teeth did not affect intubation. It was possible to achieve centric occlusion in 79 of 80 children with the endotracheal tube positioned in the retromolar space. Retromolar intubation was successfully accomplished in six pediatric patients undergoing maxillomandibular fixation and maxillofacial surgery. The retromolar space can be safely used for intubation in children when intraoperative maxillomandibular fixation, and simultaneous access to the nose and oral cavity are needed.

    Augmented reality systems can combine virtual images with a real environment to ensure accurate surgery with lower risk. This study aimed to develop a novel registration and tracking technique to establish a navigation system based on augmented reality for maxillofacial surgery. Specifically, a virtual image is reconstructed from CT data using 3D software. The real environment is tracked by the augmented reality (AR) software. The novel registration strategy that we created uses an occlusal splint compounded with a fiducial marker (OSM) to establish a relationship between the virtual image and the real object. After the fiducial marker is recognized, the virtual image is superimposed onto the real environment, forming the "integrated image" on semi-transparent glass. Via the registration process, the integral image, which combines the virtual image with the real scene, is successfully presented on the semi-transparent helmet. The position error of this navigation system is 0.96 ± 0.51 mm. This augmented reality system was applied in the clinic and good surgical outcomes were obtained. The augmented reality system that we established for maxillofacial surgery has the advantages of easy manipulation and high accuracy, which can improve surgical outcomes. Thus, this system exhibits significant potential in clinical applications.

    Open access (OA) publication has become an increasingly common route for dissemination of scientific research findings. However, it remains a contentious issue with continued debate as to its impact on the peer-review process and a potential change in the quality of subsequent evidence published. There is little research that looks into OA in oral and maxillofacial surgery. We investigated the OA policy in the 30 relevant journals listed in the Institute for Scientific Information Web of Knowledge journal citation report, comparing bibliometric data and quality of evidence produced in journals offering OA and those with subscription-only policies. 3474 articles were graded for evidence level and the results correlated to journal OA status. 76.7 % of journals offered authors OA services. There was no difference between impact factor, self-citation rate, total citations or quality of evidence between OA and subscription journals. These findings should send clear messages to both clinicians and researchers and should re- assure readers that scientific findings that are disseminated in open access form do not differ in quality to those in subscription-only format. It should reinforce that open access formats are a credible way to display research findings in oral and maxillofacial surgery.
