    Full Text Available AIM: To investigate the epidemiological characteristics of maxillofacial fractures and associated fractures in patients seen in the Oral Surgery Unit of Mulago Hospital, Kampala, Uganda. METHODOLOGY: A six-month prospective study was conducted. Data collected included socio-demographic factors, type and etiology of injury, additional fractures, and post-surgery complications. RESULTS: One hundred thirty-two (132 cases ranging from 5-70 yrs of age were reported, with a male: female ratio of 7.7:1. The 21-30 yr age group was the largest, comprising 51.51% of cases (n=68. Road traffic accidents contributed to 56.06% (n=74 of fractures. In total, 66% of the sample (n=87 suffered isolated mandibular fractures. Symphyseal and maxillary fractures were the most common mandibular and mid-facial fractures, respectively. Among associated fractures, the femur was most affected. A total of 39 (29.54% of patients had post-operative complications, of which infection accounted for 48.71% (n= 19, and malocclusion accounted for 17.94% (n=7. CONCLUSIONS: Anticipated changes in maxillofacial trauma trends necessitate regular epidemiologic studies of facial fractures to allow for development and implementation of timely novel preventive measures.

    Pediatric oral and maxillofacial surgery is rarely seen as a separate entity from adult oral and maxillofacial surgery. Many procedures are similar on adults and children; however, children have unique behavioral, anatomic, and physiologic considerations. Children also have a propensity for certain injuries and pathologic lesions. Children born with congenital anomalies may also have a special subset of needs. This article is a brief review of oral and maxillofacial surgery on the pediatric population.

    Background The etiology, demographics, fracture site in facial injury patients have been reported worldwide. However, few studies have attempted to identify changes in maxillofacial fractures over time periods and between countries. The statistics are vastly different due to variations in social, environmental, and cultural factors.

    Full Text Available Introduction Severity and complexity of combined maxillofacial trauma require not only multidisciplinary approach, but prevention of trauma is also of extreme importance, as this may reduce direct and indirect social economic losses. Understanding the trauma etiology, types, and severity may support clinical priorities determination, increase treatment effectiveness, and also may achieve certain trauma prevention. In polytrauma patients, omissions in early injury diagnostics is often observed, especially in uncooperative and intoxicated patients, as well as in patients in unconscious state. MFS is important in multiple trauma patients and is essential for exact and correct diagnosis, as well as for adequate maxillofacial trauma treatment. Purpose The aim of this study is to identify the maxillofacial fractures in patients with multiple trauma or polytrauma and to analyze whether there are any factors related to associated injuries. Material and methods A total of 352 traumatic patients were retrospectively and prospectively examined for the period of 6 years (05.2005 - 12.2011, treated at Department of Oral and Maxillofacial surgery at the St. Anna University Hospital , Sofia, on grounds of the accurately kept hospital documents in conformity with accepted standards and with ethical requirements for performing such studies. Results Associated injuries were observed in 129 patients (36%. In combined maxillofacial trauma (СMFT, the most common maxillofacial fracture is lower jaw fracture (46.5%, followed by zygomatic bone trauma (34.9% and nasal bones trauma (21.7%. The occurrence of associated injury correlated significantly with trauma mechanism and fracture type; high-speed accidents and severe facial fractures were significant predictors of associated injury. Alcohol plays a key role in maxillofacial trauma appearance, whereas the alcohol relation is significant with interpersonal injuries (42%, with falling (20% and with motor vehicle

  8. Oral myiasis in a maxillofacial trauma patient

    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.

    Although not previously reported, experience suggests that dentoalveolar injury is -common among patients with maxillofacial fractures. The objective of this study was to evaluate and describe the prevalence and nature of dentoalveolar injuries in patients identified with maxillofacial fractures. Medical records of 43 dogs and cats diagnosed with maxillofacial fractures between 2005 and 2012 were reviewed to identify patients with concurrent dentoalveolar injury. Medical records of patients with dentoalveolar injury were abstracted for the following information: signalment (including sex, age and skull type), mechanism of maxillofacial trauma, location and number of maxillofacial fractures, dentoalveolar injury type and location and the number of dentoalveolar injury per patient. Statistical evaluation was performed to determine associations between signalment, mechanism of trauma, location and number of maxillofacial fractures and the prevalence and nature of concurrent dentoalveolar injury. Dentoalveolar injuries are common among patients with maxillofacial trauma. Age and mechanism of trauma are significant predictors of the presence of dentoalveolar injuries in patients with maxillofacial trauma. The findings of this study serve to encourage veterinarians to fully assess the oral cavity in patients with maxillofacial fractures as dentoalveolar injuries are common and can be predicted by age and mechanism of trauma. © 2012 British Small Animal Veterinary Association.

    Full Text Available The aim of this research was to assess oral and maxillofacial trauma in urban and rural populations of the same region. The data collected included age, gender, year and month of trauma occurrence, origin (rural and urban, cause of injury, and the type of oral and maxillofacial trauma. Records from 1121 patients with 790 instances of oral and maxillofacial trauma were evaluated. Statistical analysis was performed with the Statistical Package for Social Sciences (SPSS version 17.0 software and involved descriptive statistics and Pearson's chi-squared test. Male patients were more prone to maxillofacial trauma (n = 537; 68%, and the patients were mostly from urban areas (n = 534; 67.6%. The male-to-female ratio was found to be 2.12:1 (urban zone, 1.72:1; rural zone, 3.49:1. The average age was 25.7 years (SD = 14.1. A traffic accident was the most common cause of oral and maxillofacial trauma (27%. The jaw (18% was the most commonly fractured bone in the facial skeleton, followed by the zygoma (12.9%. Avulsion (8.5% was the most common dental trauma. A significant statistical relationship was found between place of origin and gender (p < 0.001. Accidents involving animals were more frequent in rural areas (P < 0.001. Zygomatic fractures (p < 0.001, contusion (p = 0.003, and abrasion (p = 0.051 were the most common injuries among individuals from rural areas. Nasal fracture (p = 0.011 was the most frequent type of trauma in individuals from urban areas. According to these data, it seems reasonable to assume that specific preventive public policy for urban and rural areas must respect the differences of each region.

    The aims of this study were to provide an overview of maxillofacial trauma and its relationship to patient's demographic data and alcohol consumption within the state of Sabah. It was a retrospective study of maxillofacial trauma cases treated by Oral and Maxillofacial Surgery Department, Queen Elizabeth Hospital, Kota Kinabalu, Sabah, from January 1, 2009, until December 31, 2013. A total of 630 maxillofacial trauma cases were included. Details of the trauma were collected from patients' record, including patients' cause of injuries, injuries suffered, treatment indications, and treatment received. Patients' demographic data (age, gender), alcohol consumption in relation to causes, and type of maxillofacial injury were analyzed. There were 538 male (85.4%) and 92 female (14.6%) patients (ratio: 5.8:1), with mean age of 31.0 years. Most common causes of maxillofacial injury were motor vehicle accident (MVA; 66.3%), followed by fall (12.4%) and assault (11.6%). Motorcyclists made up more than half of the total cases (53.1%). Cases referred were primarily due to soft-tissue injury (458 cases). Other cases were dentoalveolar and maxillofacial bone fractures. Treatment provided for the fractures included open reduction and internal fixation (22.9%), closed reduction (28.7%), and conservative management (48.4%). Toilet and suturing were done for all patients with soft-tissue injury. Maxillofacial trauma is a major problem in Sabah. It affects mostly males in the age group of 21 to 30 years. Most of the MVA patients were motorcyclists. Mandibular fracture with parasymphysis involvement recorded the highest number. Most of the patients preferred conservative management, probably due to financial and logistic issue.

    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.

    Objective:To investigate the effect of straight wire appliance in the treatment of children emergency oral-maxillofacial fracture. Method .-Fifty patients with simple fracture of jaws were included in the study, 28 cases were male and 22 cases were female. The average age was 10. 5 years old. 23 cases were treated by technique of straight wire appliance, 6 cases by fixation, and 21 cases by traditional retainers. Simple condylar fracture in children was evaluated. Result: There was no infection and fracture in the 13 cases treated by technique of straight wire appliance. The healing of the fracture surface was classified to class-1 and occlusion was normal. In the following one month to two years, no abnormal eruption and secondary oral-maxillofacial deformity occurred. Two cases a-mong the 6 cases treated by fixation had abnormal eruption and malocclusion. In group treated by traditional retainers, 4 cases were infected, 2 cases had malocclusion and 1 case had limitation of mouth opening. In group with condylar fracture, oral hygiene and pain during treatment was significantly better than control group using traditional retainers. Conclusion: The fixed orthodontic appliance has obvious advantages in the treatment of children with oral maxillo/acial fracture, convinced by complete healing of fracture surface, normal occlusion and less complications. The fixed orthodontic appliance is the preferred option to treat children with oral maxillofacial fracture.%目的:探讨急诊时应用直丝弓技术治疗儿童颌骨骨折的可靠性和临床效果.方法:儿童单纯性颌骨骨折、无明显错化患者50例,男28例,女22例,平均年龄10.5岁.其中23例急诊时应用直丝弓技术,6例应用可吸收夹板作坚固内固定,21例作传统牙弓夹板固定,对3种方法的骨折愈合情况、张口度、骨折区牙齿咬合状况等进行疗效观察和对比,并对儿童单纯髁状突骨折疗效及治疗疼痛和口腔卫生做对比评价.结果:直

    Full Text Available Nowadays the trend is not to interrupt an- ticoagulants or antiplatelet drugs for minor oral surgery; They can be safely performed when the INR is 2-4. The suturing of the wound and the use of hemostatic agents reduces the possibility of postoperative bleeding. In cases of major maxillofacial interventions, the shortest possible interruption of anticoagulants is recommended in order to avoid the risk of thrombosis. The same applies to as- pirin, and in cases of dual therapy (aspirin and clopido- grel discontinuation of clopidogrel and low dose of as- pirin are recommended. In case of excessive bleeding, administration of clotting factors or fresh platelets is rec- ommended when the patient is on anticoagulants or an- tiplatelets respectively. In this literature study we report the older and the newer anticoagulants (dabigatran and rivaroxaban and an- tiplatelet drugs (prasugrel as well as the surgical man- agement of patients who take them.

    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.

    Background: Assault, though a major cause of maxillofacial injuries in the developed nations, has not been adequately investigated among Nigerian population. This study aimed to analyze the pattern of maxillofacial injuries caused by assault in our institution. Methods: A descriptive clinical survey of patients with assault-induced oral and maxillofacial injuries presenting to our maxillofacial surgery clinic/emergency ward was carried out. Demographic data and pattern of injuries obtained from patients’ record and department trauma database were analyzed. Results: 156 patients presented with oral and maxillofacial injuries between October 2009 and December 2010. Thirty-four cases were due to assault and male to female ratio was 1.8:1. The mean age of the patients was 21.4±6.26 years (age range 2–48 years). 23.6% (n=8) of the injuries were due to domestic violence between spouses while 35.3% (n=12) resulted from fight. Students unrest and armed robbery attack accounted for six cases each (17.7%, n=6), while there were two cases due to child battering. 64.3% (n=22) of the injuries sustained involved soft tissues while 35.7% involved hard tissues. Contusion was the most common isolated soft tissue injury accounting for 56% (n=10) while dentoalveolar fracture was the most encountered hard tissue injury (62.5%, n=16). Conclusion: There is need for preventive strategies to reduce the incidence of assault-induced maxillofacial injuries. PMID:24027401

    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.

    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.

    Objectives This study investigated patients with oral and maxillofacial lacerations who visited the emergency room over a three-year period in an effort to determine the optimal treatment for these injuries. Materials and Methods This study examined 1,742 patients with oral and maxillofacial lacerations with 2,014 different laceration locations who visited the emergency room of Pusan National University Hospital (Busan, Korea) over three years, from January 2011 to December 2013. Patients were classified by sex, age, visit day, cause of injury, injury site, and the presence or absence of soft tissue and tooth injuries. Results The male to female ratio was 2.50:1. Patients under 10 years old were seen most frequently. Most emergency room visits were on weekends. Among intra-oral lacerations, the lip area was the most vulnerable site; among extra-oral lacerations, the chin area was most frequently injured. The most frequent etiology was a slip down. Most lacerations occurred without bone fracture or tooth damage. Conclusion Laceration may differ in large part as compared with the fracture. Therefore, it is necessary to continue collecting data on oral and maxillofacial lacerations to establish optimal emergency room diagnosis and treatment strategies. PMID:26568926

    Obesity is defined as the accumulation of fatty tissue to such a level that overall health might be adversely affected. It is a complex, multifactorial metabolic condition which develops from interactions of genetic and environmental factors. The prevalence of obesity is increasing at an alarming rate in many parts of the world including developing countries. Subsequently, increasing number of obese patients is expected to present for oral and maxillofacial treatment. Such treatment includes routine oral and maxillofacial procedures (teeth extraction, fracture fixation, biopsies), specific corrective procedures for snoring and obstructive sleep apnea, and intermaxillary fixation for weight reduction. Obese patients provide a unique challenge because of their body habitus, medical conditions, and physiologic, response to treatment, all of which have significant consequences on the surgical procedure being performed. Therefore, the oral and maxillofacial surgeon needs to be aware of these associated medical and surgical issues and take them into consideration when treating these patients. This article reviews the clinical and surgical implications that obesity has on the delivery of oral and maxillofacial surgical and anaesthetic care.

    Sport diving has witnessed explosive growth in the past decade, as 8.5 million people are certified in the United States alone. Even though scuba diving is a relatively safe sport, there are serious risks that all divers must consider. Beyond the better-known sequelae such as decompression sickness, middle ear dysfunction, and potential central nervous system effects, scuba diving also carries inherent risk to the maxillofacial region. Atypical facial pain, temporomandibular joint dysfunction, sinus barotraumas, and barodontalgia have all been reported by dentists and physicians treating military, commercial, and sport divers. Additionally, clinicians must address anatomic concerns for would-be divers, including cleft lip and palate, edentulism, or patients with pre-existing temporomandibular dysfunction, midfacial trauma, or craniomaxillofacial surgery. Health care professionals should have a thorough understanding of the implications of scuba diving for consultation and recommendation regarding diving fitness and the treatment of adverse effects of scuba diving to the maxillofacial region.

    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.

    The fractures of the gnathic condyle are constantly increasing due to the violent impact on the chine. The functional treatment is essential for good results whereas the restitution of a functional joint, i.e. teeth that engage into one another, is satisfactory for the patient as it can also justify a possible surgical reduction in such cases when significant shifts of fragments resulting from the fractures are present.

    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

    Understanding the credentialing and privileging process is important for all practitioners. Whether applying to a medical staff for the first time, participating in the reappointment process, applying for new privileges, or challenging a clinical privilege denial, the practitioner needs to understand the process and know his or her rights. This article should assist the oral and maxillofacial surgeon and the organizations providing credentials and privileges to make the process less difficult and more efficient.

    The aim of this study was to present a large series of motorcycle- and bicycle-related traumas to the face in an attempt to identify the injury pattern in motorcyclists and bicyclists. Data were collected from patients during a 10-year period (1999 through 2009), which included demographic data, diagnosis of facial fractures, use of protective devices, dentoalveolar trauma, and facial soft tissue injuries. There were 556 patients with bicycle accidents and 367 with motorcycle accidents. Men were involved in 79% (436) of bicycles accidents and 82% (299) of motorcycle accidents. Young male patients were more frequent in bicycle and motorcycle accidents. Two hundred fifty bicyclists showed 311 maxillofacial fractures. Two hundred twenty-one motorcyclists showed 338 maxillofacial fractures. Motorcycle accidents caused multiple fractures in more patients. Seventy-six percent of motorcyclists were using helmets at the time of the accidents, whereas 6% of cyclists were using helmets. Motorcyclists showed a larger number of lacerations, whereas bicyclists showed a larger number of abrasions. Avulsion was the most common dentoalveolar injury for these accident types. Hospital stays were 3.8 days for motorcyclists and 1.3 days for bicyclists. The high-impact collisions typically observed in motorcycle accidents is directly related to larger percentages of soft tissue lacerations and facial fractures. The low-impact trauma that is observed in bicycle accidents is more commonly associated with soft tissue abrasion, hematoma, and dentoalveolar fractures. This stresses the need for compulsory legislation for helmet use with face-guards for cyclists and motorcyclists. It is important to take measures to alert the public regarding the severity of injuries likely to occur in bicycle- and motorcycle-related accidents and ways to prevent them.

  18. Oral and maxillofacial tumours in children: a review.

    Science.gov (United States)

    Sato, M; Tanaka, N; Sato, T; Amagasa, T

    1997-04-01

    This retrospective review presents our experience of oral and maxillofacial tumours in children. The subjects were 250 children under the age of 15 years (out of a total of 2747 patients with oral and maxillofacial tumours), who were treated after histopathological confirmation of their diagnoses during the 28 years 1965-92. Diagnosis, incidence, and age at presentation were the main outcome measures and the results showed that 232 patients (93%) had benign tumours and 18 (7%) were malignant. The most common benign tumour was haemangioma (n = 69) and the most common malignant tumour sarcoma (n = 14). The most common odontogenic tumour was odontoma (n = 47) and non-odontogenic tumour ossifying fibroma (n = 5). The most common site of soft tissue tumours was the tongue (n = 65) and of bony tumours the mandible (n = 62). About a third of the tumours developed in patients between the ages of 6 and 11 years. Most of the angiomas developed in patients less than 6 years old, and most of the ameloblastomas in those over 12 years of age. Children accounted for 55% of patients with lymphangoma, 41% of those with odontoma, and 22% of those with haemangioma. It is concluded that most of these lesions were probably developmental malformations rather than neoplasms, and that the definition of oral and maxillofacial tumours in children should be reconsidered.

    Oral and maxillofacial surgeons traditionally have musculoskeletal pain. The aim of this study was to determine the postural preferences of oral and maxillofacial surgeons and their effect on musculoskeletal pain. The authors designed and implemented a cross-sectional study. The association of demographic characteristics with postural preferences and use of loupes was explored. Then, the relation of demographic characteristics, postural preferences, and use of loupes to painful musculoskeletal complaints was analyzed. Contingency analysis was used to compare participants' responses and multiple logistic regression analysis was used to identify relevant predictor variables. The sample was composed of 153 oral and maxillofacial surgeons, of which 32% indicated that they had ever had pain attributable to their practice that lasted longer than 2 weeks. Practitioners reported neck and back pain as being most common. Eighty-four percent of practitioners stood for extractions and placement of implants. Those who stood did so for visibility. Practitioners who sat indicated they did so for orthopedic reasons (P < .001). Thirty-one percent of practitioners indicated loupes use. Those who used loupes were more likely to report pain (P = .022). Most respondents stood and did not use loupes. Those who did use loupes were more likely to report pain. Those who stood did so for visibility; those who sat did so for orthopedic reasons. Almost one third of respondents reported pain lasting at least 2 weeks during practice. Copyright © 2017.

    A retrospective study was performed to assess maxillofacial fractures in patients treated at the public "S.M. Goretti Hospital" hospital from 2011 to 31/8/2012. Data were prospectively recorded including age and sex, cause and mechanisms of injury, soft tissue injuries, dentoalveolar trauma, facial bone fractures and type of treatment. The pre-surgical and post-surgical hospitalization days were also analysed. Causes were grouped into five categories: road traffic collision, sports accidents, occupational accidents, assaults and domestic accidents. The analyses involved descriptive statistics. Records from 83 patient sustaining 95 maxillofacial fractures were evaluated. The zygoma was the most fractured anatomical site in both males and females, accounting for 32% of injuries, followed by isolated fracture of the orbital floor (blow-out and blow-in) with 11%. The age group between 18 and 39 years showed the highest rate of incidence of maxillofacial fractures. Men were more involved than women in all cases with a male:female ratio of 5,4:1. Accidents were the most frequent cause of maxillofacial fractures in the age group between 18 and 39 years and interpersonal violence was the most frequent cause of maxillofacial fractures in the age group between 40 and 59 years. Facial fractures occurred primarily among men under 30 years of age, and the most common sites of fractures in the face were the mandible and the zygomatic complex. Road traffic collisions were the main aetiologic factor associated with maxillofacial trauma.

    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 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.

  4. Laser tumor treatment in oral and maxillofacial surgery

    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 OBJECTIVE: This study aimed to evaluate oral and maxillofacial trauma caused by falls during epileptic seizures. METHOD: A prospective case-control study was carried out among patients recruited from both the Epileptic Outpatient Clinic and the Emergency Room of Hospital de Base during 2006. The study group was composed of patients with epilepsy that had been diagnosed by a specialist. Oral and maxillofacial trauma was diagnosed using a questionnaire together with physical and radiographic examinations. A control group was formed from non-epileptic relatives or neighbors of the patients. The two groups were compared with regard to the number and type of oral and maxillofacial trauma events suffered. Odds ratios with a 95% confidence interval, dependency analysis and the Pearson c² test were used for statistical analysis, and the significance level was set at p≤0.05. RESULTS: A total of 159 patients with epilepsy (91 males; 57.3% and 68 control individuals (28 males; 41.1% were enrolled in the study. The frequencies of oromaxillary trauma in the study and control groups were 23.9% and 4.4%, respectively. Generalized tonic-clonic, generalized and non-classified seizures were strongly associated with trauma. The commonest lesions were fractures of dental tooth crowns (32.9%, followed by tooth avulsion (7.6%, tooth luxation (5% and fracturing of prostheses in edentulous patients (3.8%. CONCLUSION: This work shows that injuries to the face and teeth are statistically more common in patients with epilepsy than in the general population, and that individuals who suffer seizures without aura are the most affected.

    The incidence of facial trauma is high. This study has the primary objective of documenting and cataloging maxillofacial fractures in polytrauma patients. From a total of 1229 multiple trauma cases treated at the Emergency Room of the Santo Antonio Hospital - Oporto Hospital Center, Portugal, between August 2001 and December 2007, 251 patients had facial wounds and 209 had maxillofacial fractures. Aged ranged form 13 to 86 years. The applied selective method was based on the presence of facial wound with Abbreviated Injury Scale ≥1. Men had a higher incidence of maxillofacial fractures among multiple trauma patients (86.6%) and road traffic accidents were the primary cause of injuries (69.38%). Nasoorbitoethmoid complex was the most affected region (67.46%) followed by the maxilla (57.42%). The pattern and presentation of maxillofacial fractures had been studied in many parts of the world with varying results. Severe multiple trauma patients had different patterns of maxillofacial injuries. The number of maxillofacial trauma is on the rise worldwide as well as the incidence of associated sequelae. Maxillofacial fractures on multiple trauma patients were more frequent among males and in road traffic crashes. Knowing such data is elementary. The society should have a key role in the awareness of individuals and in prevention of road traffic accidents.

    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.

    Whether new to private practice or a seasoned practitioner, an oral and maxillofacial surgeon (OMS) needs to understand how to handle complicated and often stressful negotiations of contracts for which he or she usually is untrained. This article is designed to give a general understanding of certain common contractual language. It is not comprehensive in scope, but it attempts to cover contracts that are most often seen by an OMS in practice. It is a general discussion of common legal concepts that could face an OMS, but it is not, nor is it intended to be, legal advice.

    Hemophilia will be encountered in the oral and maxillofacial surgeon's office. A thorough understanding of hemophilia is necessary to safely care for these patients. One must understand the severity of the patient's hemophilia as well as whether or not inhibitors are present. The patient's surgical management will be influenced by these two factors. In addition to the possible need to transfuse factors or desmopressin, special care must be taken perioperatively to avoid bleeding complications. This article reviews the overall management of hemophilia A and B as well as the specific perioperative management of these patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    2005-08-01

    Improvised explosive devices have created a new class of casualties that presents a unique surgical challenge for oral and maxillofacial surgeons. The injury pattern and severity are different from those seen in conventional trauma patients. Because of battlefield circumstances, patients are sometimes delayed significantly in their transport to a trauma center, and they frequently arrive at a trauma center with hypotension, hypothermia, and acidosis. Definitive care is delayed while the hemodynamic status and life-threatening injuries are stabilized. Hospital triage protocols must be well established in advance to prepare a timely response to the mass casualty event. Proper resource use is an ever-evolving challenge for hospital staff during these times.

  12. Submandibular intubation as an alternative for intra-operative airway management in maxillofacial fractures - our institutional experience

    Praveer K Banerjee

    2016-01-01

    Full Text Available Background and Aims: Airway management in anaesthesia for maxillofacial surgical procedures is tricky at times when the nasal/oral routes are contraindicated or are impossible. Tracheostomy as an alternative inherits its own complications. We present a case series of the submandibular route for tracheal intubation as an alternative. Methods: The procedure was performed in ten selected adult patients with maxillofacial/mandibular fractures associated with a fracture of skull base or nasal bone. All of them were medically stable with no need of intensive care or mechanical ventilation in post-operative period. Results: Submandibular intubation in all ten patients of panfacial fractures allowed uninterrupted surgical techniques with a secured airway. All patients were reverted to oro-tracheal tube at the end of surgery as immediate maxillomandibular fixation was not necessary. The patients were extubated after recovery from anaesthesia before they left the operating theatre. One patient in the post-operative period had a superficial infection of incision site that responded well to local treatment. No other complications were encountered in the intra-operative or post-operative period. Conclusion: In complex maxillofacial injuries, when oral or nasal intubation hampers surgeon′s field of view, submandibular intubation offers an effective alternative to short-term tracheostomy along with small risk potential. There is a need to emphasise its regular application in such cases so that technique can be mastered by both surgeons and anaesthesiologist.

    In 2006, it was 50 years ago that the oral and maxillofacial surgery was officially recognized as a dental speciality in The Netherlands. During those five decades, oral and maxillofacial surgery significantly evolved, which is nicely reflected by the changes in the name of the scientific society su

    Oral and maxillofacial surgeons have shown curiosity and concern for their present and future patterns of practice and workforce needs. Few oral and maxillofacial surgeons would not have an understanding of how they came to be, or opinions on where the specialty is and appears to be going. Such opinions, however, need to be rigorously tested against the best available information. Quantitative information is the substantive input to decisions on whether oral and maxillofacial surgeons wish to go where they appear to be going, and if so why, and if not, why not? The Oral and Maxillofacial Surgeons 1990 Workforce Study* aimed to provide information relevant to these questions. Oral and maxillofacial surgeons are surprising in both their heterogeneity in patterns of practice and homogeneity in most of the content of services provided. Projections of the workforce indicate that a status quo in recruitment is actually a steady decline in capacity to serve the community, a picture in contrast to the international comparative data and opinion that supports a broadening in the service role of oral and maxillofacial surgeons. The Oral and Maxillofacial Surgeons 1990 Workforce Study offers insights into present and future patterns of practice and workforce needs. Ultimately, however, decision-making in the specialty will reflect additional social, economic and dento-political factors to which the Australian and New Zealand Association of Oral and Maxillo-Facial Surgeons must be the major contributor.

    This review examines the effect of publishing case reports on journal impact factor and future research. All case reports published in the four major English language oral and maxillofacial surgery journals in the two year period, 2007-2008, were searched manually. The citation data of each case report were retrieved from the ISI online database. The number, percentage and mean citations received by case reports and their relation to the 2009 journal impact factor were analysed. Case reports which received more than 5 citations were also identified and all of the citing articles retrieved and analysed. Thirty-one percent of all articles published in major oral and maxillofacial journals in 2007-2008 were case reports. Case reports had a low citation rate with a mean citation of less than 1. There were 38 (7.2%) case reports with more than 5 citations and 30% of the citing articles were also case reports. The publication of case reports negatively affected journal impact factor which correlated directly with the percentage of case reports published within a journal. Case reports reporting recent topics, describing new treatment/diagnosis method and with a literature review were more likely to receive citations.

    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.

    Using the international organonymy is mandatory as well for daily clinical practice as for research and teaching our students. The international organonymy, Nomina Anatomica, is in Latin. A rather unsuccessful attempt at using a French version of the international organonymy in clinical practice has been made in France. Eponyms have been systematically contraindicated; the definitions of general anatomy are applied, as well as a systematic Gallicization of the Latin terminology. Despite a stringent observance of these rules, some terms remain inappropriate because they are misleading or inaccurate. Furthermore, using this language used worldwide remains uneasy in daily clinical practice. We had for objective to focus on the main anatomical terms used routinely in oral and maxillofacial surgery, and to justify their use in clinical practice, research, and education.

    2016-03-01

    The use of synthetic materials to repair craniofacial defects is increasing today and will increase further in the future. Because of the complexity of the anatomy in the head and neck region, reconstruction and augmentation of this area pose a challenge to the surgeon. This review discusses key facts and applications of traditional reconstruction bone substitutes, also offering comparative information. It then describes the properties and clinical applications of bioactive-glass (B-G) and its variants in oral and maxillofacial surgery, and provides clinical findings. The discussion of each compound includes a description of its composition and structure, the advantages and shortcomings of the material, and its current uses in the field of osteoplastic and reconstructive surgery. With a better understanding of the available alloplastic implants, the surgeon can make a more informed decision as to which implant would be most suitable in a particular patient.

    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.

    The use of smartphones has soared among healthcare professionals in recent years, with estimated figures reporting that the majority of clinicians own and use smartphones in the workplace. Smartphones allow the clinician to carry textbooks in their pocket, write documents on the move and use email and internet to enhance productivity and clinical decision making. These advances in smartphone technology have enabled access to healthcare information for the clinician and transfer of data between team members, giving rise to the phenomenon of telemedicine. With the ability to instantly transfer clinical data to the off-site surgeon, combined with purpose-built medical apps, the smartphone is rapidly becoming an invaluable tool for the modern surgeon. Many studies have linked the benefits of smartphones and apps in other surgical specialities, but no article to date has highlighted the merits and full scope of this technology to the Oral and Maxillofacial Surgeon. We report that 94 % of British maxillofacial surgery trainees own a smartphone, with 61 % owning an iPhone. 89 % of trainees questioned had downloaded medical apps and used them regularly during clinical activities. We discuss the clinical application of the smartphone in the field of oral and maxillofacial surgery and review a list of useful and relevant apps for the modern maxillofacial surgeon using the iPhone as an example platform.

    The current scope of oral and maxillofacial surgery in Australia and New Zealand was explored with a survey of full members of the Australian and New Zealand Association of Oral and Maxillofacial Surgeons resident in the region. There was an 83 per cent usable response rate and the objectivity of the data was confirmed by check questions and material from other sources. The study showed that oral and maxillofacial surgery is the surgical specialty of dentistry with the core of referral and surgical services being dento-alveolar. However, the essential knowledge of the anatomy, pathology, and surgery of the orofacial region forms the basis for the wider scope of modern oral and maxillofacial surgery. Current surgery includes management of trauma, pathology, dentofacial deformity, and a wide range of reconstructive surgery including grafts and implants.

    Full Text Available Pediatric soft tissue sarcomas of the oral/maxillofacial region are rare neoplasms that present significant difficulty with respect to treatment and local control measures. We report four cases of pediatric oral/maxillofacial soft tissue sarcomas from our tertiary care pediatric hospital and emphasize the rarity of these malignancies and the challenges encountered in treating these lesions, and suggest areas for further research. We conclude that multimodal therapy and interdisciplinary cooperation are paramount to successful management of these lesions.

    2014-12-01

    Full Text Available Objectives: In several epidemiological studies of maxillofacial trauma, falls were one of the most frequent causes of facial injury. The aim of this study is to analyse the patterns of fall-related maxillofacial injuries based on the height of the fall. Material and Methods: Using a systematic computer-assisted database of patients hospitalised with maxillofacial fractures, only those with fall-related injuries were considered. The falls were divided into four groups: falls from slipping, tripping or stumbling (STSF, loss of consciousness (LOCF, stairs (SAF, and height (HF. Data on the age, gender, fracture site, Facial Injury Severity Scale (FISS, facial lacerations, associated lesions, type of treatment, and length of hospital stay were also analysed. Results: This study included 557 patients (338 males, 219 females; average age 51.5 years [range 4 - 99 years]. In the over 60 age group, females were more prevalent in STSF than males. According to aetiology, STSF was the most frequent cause of maxillofacial fractures (315 patients; 56.5% followed by LOCF (157; 28.2%, HF (55; 9.9%, and SAF (30; 5.4%. The middle third of the face was affected most frequently. After LOCF, however, the inferior third was prevalently involved. The majority of associated fractures, as well as the most severe injuries and greatest rate of facial lacerations, occurred secondary to HF. Conclusions: This study showed that fracture severity and site are influenced not only by patient age, but also by the nature of the fall.

    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.

    Background The epidemiology of facial injuries varies in different countries and geographic zones. Population concentration, lifestyle, cultural background, and socioeconomic status can affect the prevalence of maxillofacial injuries. Therefore, in this study, we evaluated the maxillofacial fractures epidemiology and treatment plans in hospitalized patients (2012-2014) which would be useful for better policy making strategies. Material and Methods In this retrospective study, the medical records of 386 hospitalized patients were evaluated from the department of maxillofacial surgery at Bahonar Hospital of Kerman, Iran. The type and cause of fractures and treatment plans were recorded in a checklist. For data analysis, ANOVA, t-test, Chi-square, and Fisher’s exact test were performed, using SPSS version 21. Results The majority of patients were male (76.5%). Most subjects were within the age range of 20-30 years. Fractures were mostly caused by accidents, particularly motorcycle accidents (MCAs), and the most common site of involvement was the mandible (parasymphysis). There was a significant association between the type of treatment and age. In fact, the age group of 16-59 years under went open reduction internal fixation (ORIF) more than other age groups (P=0.02). Also, a significant association was observed between gender and the occurrence of fractures (P=0.01). Conclusions Considering the geographic and cultural indices of the evaluated population, it can be concluded that patients age and gender and trauma causes significantly affect the prevalence of maxillofacial traumas and fracture kinds and treatment plans. Key words:Epidemiology, treatment, facial injuries, face fractures, maxillofacial trauma, trauma. PMID:26116845

    The risk of bias is important in the interpretation of the results of research. The aim of this review was to evaluate the risk of bias in randomised controlled trials (RCTs) in oral and maxillofacial surgery (OMFS) over a 10-year period. We searched databases of publications for RCTs published between January 2000 and January 2010. Papers were assessed with 2 up-to-date logical quality lists, the Delphi list and the Jadad scale. Those papers with a low risk of bias were given a Jadad score ≥4 (range 0-5) and a Delphi score ≥6 (range 0-9). A total of 230 papers met the inclusion criteria, and only 41 (18%) were assessed as being at low risk. Most of those included did not correctly describe such important items for risk of bias as method of randomisation (n=124, 54%), concealment of allocation (n=143, 62%), blinding (n=175, 76%), and intention-to-treat analyses (n=182, 79%). In the fields of implantology, traumatology, obstructive sleep apnoea syndrome, and extractions, no paper had a low risk of bias. This systematic review has shown a shortage of research in OMFS with a low risk of bias published over a 10-year period. Further research should concentrate on better describing items at important risk of bias.

    Tissue engineering is a rapidly advancing discipline that combines the attributes of biochemical and biomaterial engineering with cell transplantation to create bio-artificial tissues and organs. For the oral and maxillofacial surgeon, the reconstruction of maxillofacial defects in hard and soft tissues is an ongoing challenge. While autologous grafts and vascularised free flaps are the current gold standard, they are not without complications at both the donor and reconstructed sites. Tissue engineering, which aims to create tissue-matched, prefabricated, prevascularised bony or soft tissue composite grafts, or both, therefore has the potential to revolutionise practice in maxillofacial surgery. We review the technology of tissue engineering and its current and future applications within the specialty, and discuss contemporary obstacles yet to be overcome.

The present study aimed at investigating the frequency of oral and maxillofacial pediatric and adolescent biopsies in Zahedan (southeast Iran, and compare the results with other epidemiologic studies.Methods and Materials This retrospective study reviewed oral and maxillofacial lesions in patients with 0-18 years old referring to the treatment centers of Zahedan University of Medical Sciences during 12-years period. Patients’ demographic information including age, gender and location of the lesion were collected and statistically analyzed.ResultsIn general, among 1112 oral and maxillofacial lesions, 154 (13.9% cases were related to children and adolescents younger than 18 years old. The average age of patients was 11.4 ± 4.9, 53.2% and 46.8% of them were boys and girls, respectively. The most frequent sites of lesions were the gingiva and lip. The most prevalent lesions included inflammatory/reactive, cystic and neoplastic lesions, respectively. Benign and malignant tumors comprised 12.3% and 4.5% of cases. Moreover, pyogenic granuloma and peripheral giant cell granuloma (PGCG were the most frequent lesions.ConclusionThe most prevalent oral and maxillofacial lesions in patients under 18 years old were inflammatory/reactive lesions in gingiva and in the 13-18 age range. Determining the characteristics of these lesions in the children and adolescents population provides a firm groundwork for proper diagnosis and treatment.

    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.

    Molecular biology is an exciting, rapidly expanding field, which has enabled enormously greater understanding of the biology of diseases and malfunctions in many fields. It chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interrelationship of DNA, RNA and protein synthesis and how these interactions are regulated. Since the introduction of molecular biology into modern science, numerous other fields have been enabled to go "molecular". Advanced molecular biological techniques showed us new avenue towards finding answers to the questions asked for decades. The first part of this article described the history of molecular biology.It started as a joined discipline of other areas of biology, i.e. genetics and biochemistry in the 1930s and 1940s, and enjoyed its classical period and became institutionalized in the 1950s and 1960s. Major molecular techniques manipulating proteins, DNA and RNA were introduced and their mechanisms were concisely illustrated. The current knowledge of molecular biology and their applications in orthodontic and oral and maxillofacial surgery, i.e. osteoclast differentiation and function, regulation of tooth movement, mechanotransduction/cell-signalling, bone fracture healing, oral cancer as well as craniofacial/dental anomalies and distraction osteogenesis were discussed. Although the problems of introducing molecular technologies are still substantial, it is anticipated that the future of medicine/dentistry will be "molecular": molecular prevention, molecular diagnosis and molecular therapy.

    China is currently in the process of establishing formal residency training programs in oral and maxillofacial surgery and other medical and dental specialties. Regulatory agencies, and educational and academic institutions in China are exploring mechanisms, goals and standards of residency training that meet the needs of the Chinese healthcare system. This article provides an introduction of residency training in oral and maxillofacial surgery in the United States, with emphasis on the accreditation standard by the Commission on Dental Accreditation. As there are fundamental differences in the medical and dental education systems between China and United States, the training standards in the United States may not be entirely applicable in China. A competency-based training model that focus on overall competencies in medical knowledge, clinical skills and values at the time of graduation should be taken into consideration in a Chinese residency training program in oral and maxillofacial surgery.

    2014-10-01

    Research in oral and maxillofacial surgery has focused mainly on principles founded in the biological and chemical sciences, which have provided excellent answers to many questions. However, recent technologic advances have begun to gain prominence in many of the medical sciences, providing clinicians with more effective tools for diagnosis and treatment. The era of modern physics has led to the development of diagnostic techniques that could provide information at a more basic level than many of the current biochemical methods used. The goal of this report is to introduce 2 of these methods and describe how they can be applied to oral and maxillofacial surgery.

    For the oral and maxillofacial surgeon, many patients will be on heparin products during surgery. So far, there is no standardized approach to treating anticoagulated patients during oral and maxillofacial surgical procedures. When a patient is on heparin therapy, heparin may be stopped 4 to 6 hours before surgery and resumed once hemostasis is achieved, usually within 24 hours. If low-molecular-weight heparin is administered, the treatment is generally stopped at least 12 hours before surgery and then resumed in a similar fashion. Local measures are generally enough to provide adequate hemostasis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Objective To introduce the concept and rational regimens and present the latest development of combined treatment of oral and maxillofacial malignancies.Data sources The related published literature was searched through the CNKI database and MEDLINE using the terms of oral cancer, oral and maxillofacial malignancies, combined and sequential therapy, multidisciplinary approach.Study selection The available related literature was read and evaluated. Studies that met the inclusion criteria were selected.Results The results show that oral and maxillofacial malignancies diagnosed at an eady stages (stages Ⅰ and Ⅱ) can be well treated with surgery alone and/or radiotherapy with optimal outcome, but advanced or recurrent diseases should be treated with rational combined and sequential treatment modalities. The use of concomitant chemoradiotherapy,taxane-containing, three-drug induction regimens and Cetuximab in combination with chemotherapy or radiotherapy demonstrated favorable results in previously untreated patients with head and neck squamous cell carcinoma.Conclusions The concept of combined and sequential treatment of advanced oral and maxillofacial malignancies should be widely accepted, and the rational regimen for individual and each type of entity should be determined based on the anatomical site and the patient's performance status.

    Flipped classroom is a new teaching model which is different from the traditional teaching method. The history and characteristics of flipped classroom teaching model were introduced in this paper. A discussion on how to establish flipped classroom teaching protocol in oral and maxillofacial surgery education was carried out. Curriculum transformation, construction of education model and possible challenges were analyzed and discussed.

    Sedation is an important component of day care oral and maxillofacial surgical procedures under local anesthesia. Although various sedative drugs in different regimens have been used for sedation, an ideal agent and regimen are yet to be established. The aim of this study is to compare the efficacy of intravenous (IV) dexmedetomidine and midazolam as a sedative agent for day care oral and maxillofacial surgical procedures. The study was conducted in the Department of Oral and Maxillofacial Surgery, SCB Dental College and Hospital, Cuttack, Odisha, India. A total of sixty adult patients of age group 18-65 years, of either sex were randomly selected equally in two groups for the study. One group named Group D received dexmedetomidine and the other named Group M received midazolam. Patients were evaluated for oxygen saturation (SPO2), respiration rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), Ramsay sedation score, bispectral index (BIS) score, amnesia, Aldrete score, relaxation during the surgery, and drug preference. Midazolam was associated with greater amnesia. Dexmedetomidine was associated with lower heart rate, SBP, and DBP. There was no significant difference in SPO2, RR, Aldrete score, Ramsay sedation score, and BIS score between the two drugs. Patient preference and relaxation were more in dexmedetomidine group. IV dexmedetomidine is a comparable alternative to midazolam for sedation in day care oral and maxillofacial surgery under local anesthesia. It is the preferred drug when a lower heart rate and blood pressure or less amnesia is needed without any serious side effects.

    As duplicate publication is unethical, our aim was to find out how common it is among published papers on oral and maxillofacial surgery. We used PubMed to identify index articles published in 2010 in the Journal of Oral and Maxillofacial Surgery, the British Journal of Oral and Maxillofacial Surgery, and the European Journal of Cranio-Maxillo-Facial Surgery, and searched for possible duplicate publications from 2008 to 2012 using the first or second and last authors' names. Suspected duplicates were categorised into "non-duplicate" (no overlap), "duplicate" (identical results and conclusions), or "salami-sliced" publications (part of the index article repeated or continued). Of the 589 index articles, 17 (3%) had some form of duplication, but specifically, we found 3 duplicate, and 15 salami-sliced publications. Most redundant articles originated from China (n=4), followed by Italy, Japan, and Germany (3 from each) and the United States and Denmark (2 each). Of the 18 redundant publications, 9 did not reference the related index article. Duplicate material is still being published, and salami-slicing is relatively common among publications on oral and maxillofacial surgery. Further research is required into the extent and impact of this finding.

    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.

    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.

    2011-09-01

    This is the first national audit of Fellows of the British Association of Oral and Maxillofacial Surgeon with the specific purpose of supporting consultant revalidation. The audit was performed online. There were 127 responses from 275 email invitations. The audit reflects the range of activity by consultants with over 90% being involved in dento-alveolar, trauma and oral medicine. 78% of consultants performing head and neck oncology had a database and 75% of cleft lip and palate surgeons. Contributions to audits in the last 3 years were least common in oral medicine (7%), skull base (7%), aesthetic surgery (8%), and paediatric maxillofacial surgery (12%). There were many different audits reflected in consultants responses and there is merit in focusing on specific audits suitable for national comparison and benchmarking.

    Full Text Available Background: Despite advancements in airway management, treatment of fractures in the maxillofacial region under general anesthesia remains a unique anesthetic challenge. We reviewed the pattern of airway management in patients with maxillofacial fractures and assessed those challenges associated with the different airway management techniques employed. Materials and Methods: The anesthetic chart, theatre and maxillofacial operations records of patients who had reduction and immobilization of various maxillofacial fractures over a 2-year period were reviewed. Information obtained included the patient demographics, mechanisms of injury, types of fractures and details about airway management. Statistical Package for Social Sciences, SPSS version 17.0 was utilized for all data analysis. Results: Fifty-one patients were recruited during the 2-year study period. Mask ventilation was easy in 80-90% of the patients, 80% had Mallampati three or four, while 4 (7.8% had laryngoscopy grading of 4. There was no statistically significant difference between the fracture groups in terms of the laryngoscopy grading (P = 0.153 but there was statistical significant difference in the technique of airway management (P = 0.0001. Nasal intubation following direct laryngoscopy was employed in 64.7% of the patients, fiber-optic guided nasal intubation was utilized in only 7.8%. None of the patients had tracheostomy either before or during operative management. Conclusion: Laryngoscopic grading and not adequacy of mouth opening predicted difficult intubation in this group of patients in the immediate preoperative period. Despite the distortions in the anatomy of the upper airway that may result from maxillofacial fractures, nasal intubation following direct laryngoscopy may be possible in many patients with maxillofacial fractures.

    Science.gov (United States)

    2015-01-01

    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

  14. Administration of Coagulation-Altering Therapy in the Patient Presenting for Oral Health and Maxillofacial Surgery.

    Halaszynski, Thomas M

    2016-11-01

    Oral health care providers are concerned with how to manage patients prescribed coagulation-altering therapy during the perioperative/periprocedural period for dental and oral surgery interventions. Management and recommendation can be based on medication pharmacology and the clinical relevance of coagulation factor levels/deficiencies. Caution should be used with concurrent use of medications that affect other components of the clotting mechanisms; prompt diagnosis and any necessary intervention to optimize outcome is warranted. However, evidence-based data on management of anticoagulation therapy during oral and maxillofacial surgery/interventions is lacking. Therefore, clinical understanding and judgment are needed along with appropriate guidelines matching patient- and intervention-specific recommendations.

    2016-06-01

    Despite constituting a minority of senior house officers (SHO) in oral and maxillofacial surgery (OMFS), the number of singly-qualified medical trainees is growing. We describe the experience of a singly qualified medical trainee in OMFS and the unique benefits and opportunities for potential trainees and the department. Overall, the advantages of synergistic training outweigh any deficiencies in knowledge, and in our experience, having both medical and dental trainees in our unit has maximised training opportunities and provided a more holistic approach to patient care. Increased exposure to conditions in the head and neck also benefits trainees who wish to pursue careers in other specialties such as ear, nose, and throat (ENT), neurosurgery, ophthalmology, and plastic surgery.

    Endovascular techniques are essential for controlling acute head and neck bleeding that cannot be controlled by local or systemic measures. Detailed knowledge of the head and neck vascular anatomy, advances in catheterization techniques, and the availability of new embolic materials have improved the safety, efficacy, and predictability of these procedures. To improve patient safety, the oral and maxillofacial surgeon must be familiar with these techniques. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

  19. The evidence base for oral and maxillofacial surgery: 10-year analysis of two journals.

    2012-01-01

    All articles published in the British Journal of Oral and Maxillofacial Surgery (BJOMS) and the International Journal of Oral and Maxillofacial Surgery (IJOMS) between January 1999 and December 2009 were classified by study design and evaluated to find the evidence base in oral and maxillofacial surgery (OMFS). Those in related specialties, and the impact factor of related dental journals were also compared. From a total of 3294 articles (1715 (52%) BJOMS; and 1579 (48%) IJOMS) most of the studies were observational or descriptive (36% BJOMS; and 31% IJOMS). Review articles constituted 5% in the British Journal and 6% in the International Journal. Analytical (non-controlled) studies made up 6% and 7% of the studies in the British Journal and the International Journal, respectively. There were 28 randomised controlled trials (RCT) (2%) in the British Journal and 40 (3%) in the International Journal. One meta-analysis was recorded in the International Journal, and one closed loop audit was recorded in the British Journal. Forty percent of the papers in both journals were non-clinical, scientific, or animal studies. The number of RCTs published in OMFS is low and is comparable with the related specialties of ear, nose, and throat (ENT) (1%) and plastic surgery (4%). Greater effort is required to carry out quality research if we are to provide the best possible evidence to patients for our interventions.

    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.

  1. A review of oral and maxillofacial surgery journals' contribution to undergraduate surgical education.

    Ologunde, Rele; Sykes, Mark

    2014-12-01

    We searched the Medline database of 4 leading international journals of oral and maxillofacial surgery (OMFS) for all articles containing the terms "undergraduate", "medical student", or "dental student" in the abstract, title, or keywords, from the earliest paper to 2013, to identify and review publications that related to the education of undergraduate medical and dental students. We found 130 articles, of which 22 (17%) met the inclusion criteria. Most were published by teams based in the United States, followed by those from the United Kingdom and Germany. The earliest was published in 1986. Since then, most have been published in the Journal of Oral and Maxillofacial Surgery (0.33/year) and the least in the International Journal of Oral and Maxillofacial Surgery (0.11/year). Eleven original research articles concerned dental students and 4 concerned medical students. Three studies looked at both groups and compared them with their qualified counterparts. There is a relative paucity of articles relating to the education of undergraduates, particularly medical students, in OMFS journals, although the number has increased over the last decade. There is a need for more educational papers to be aimed at students interested in pursuing OMFS as a career.

    2011-06-01

    Objective-To describe clinical features of oral and maxillofacial osteomas in cats. Design-Retrospective case series. Animals-7 cats with oral or maxillofacial osteoma or both. Procedures-Medical records were reviewed for information on signalment, history, clinical signs, physical examination findings, diagnostic imaging findings, results of serum biochemical analyses and histologic testing, surgical procedures performed, and perioperative complications. Outcome was determined on the basis of follow-up telephone interviews of owners. Results-Cats ranged from 1 to 23 years of age. Clinical signs were observed in 5 cats and were attributed to the presence of the mass. Diagnostic imaging (radiography and computed tomography) and histologic examination confirmed the diagnosis of osteoma. Three cats were euthanatized; 1 cat was treated by mandibulectomy, 1 was treated by maxillectomy, and 2 were treated by debulking. At the time of follow-up at least 1 year after surgery, all 4 treated cats were alive, with owners reporting an acceptable quality of life. Conclusions and Clinical Relevance-Osteoma of the oral and maxillofacial regions is an uncommon tumor in cats. Most cats are examined during an advanced stage of the disease, when treatment options may be limited. Although osteoma is a benign tumor, the recommendation is to perform a clinical evaluation, diagnostic imaging, biopsy, and treatment early in the disease process, when less invasive surgical approaches may be feasible.

  3. Alcohol-related violence and the role of oral and maxillofacial surgeons in multi-agency prevention.

    Warburton, A L; Shepherd, J P

    2002-12-01

    The maxillofacial region is by far the most frequently selected target in assaults on adults. There is a causal link between alcohol intoxication and injury. Therefore, oral and maxillofacial surgery is, in effect, the lead speciality for those injured in violence and has a responsibility to orchestrate holistic care that takes into account mental health needs. Recent years have also seen a determined effort by oral and maxillofacial surgeons to get involved in wider issues of prevention, exemplified by the national UK BAOMS Facial Injuries Awareness Week. Multi-agency prevention, not just with mental health professionals in the case of individual patients, but also with emergency medicine, public health, local government, the police and the voluntary sector is key to success. Given the potential complexity of collaborations like this, it is important to understand what works in multi-agency prevention. This paper reviews successful interventions: their rationale and how oral and maxillofacial surgeons can contribute to local injury prevention.

    The study objectives were to characterize maxillofacial injuries and assess the safety of in-theater facial fracture repair in U.S. military personnel with severe combat trauma from Iraq and Afghanistan. We performed a retrospective chart review of the Expeditionary Medical Encounter Database from 2004 to 2010. 1,345 military personnel with combat-related maxillofacial injuries were identified. Injury severity was quantified with the Abbreviated Injury Scale and Injury Severity Score. Service members with maxillofacial injury and severe combat trauma (Injury Severity Score ≥ 16) were included. The distribution of facial fractures, types, and outcomes of surgical repairs, incidence of traumatic brain injury, concomitant head and neck injuries, burn rate/severity, and rates of Acinetobacter baumannii colonization and surgical site infection were analyzed. The prevalence of maxillofacial injury in the Expeditionary Medical Encounter Database was 22.7%. The most common mechanism of injury was improvised explosive device (65.7%). Midface trauma and facial burns were common. Approximately 64% of the study sample sustained traumatic brain injury. Overall, 45.6% (109/239) had at least one facial bone fracture. Of those with facial fractures, 64.2% (n = 70) underwent surgical repair. None of the service members who underwent in-theater facial fracture repair developed A. baumannii facial wound infection or implant extrusion.

    This study evaluated the failure and complication rates of sedation in ambulatory patients undergoing oral and maxillofacial surgery. This retrospective cohort study was carried out among 619 patients who had undergone maxillofacial surgical procedures under intravenous sedation with midazolam and fentanyl. Each patient's age, American Society of Anesthesiologists (ASA) classification, systemic condition, surgical procedure, complications, and failures were recorded for evaluation. A total of 400 patients with ASA I, 199 with ASA II, and 20 with ASA III between the ages of 9 months and 84 years were included in the study. The most common systemic disorders in our patients were mental retardation (35%), hypertension (19%), and epilepsy (15%). Evaluation of the cases revealed 9 complications (1.4%) and 9 sedation failures (1.4%). The complications were bradycardia, postoperative agitation and hallucination, drug reaction, vomiting and nausea, desaturation, and hypotension. Our results in the oral and maxillofacial surgery clinic revealed low complication and failure rates. Crown Copyright © 2012. Published by Mosby, Inc. All rights reserved.

    Oral and maxillofacial surgery in veterinary medicine carries the risk of severe hemorrhage due to the great vascular supply of the head. Temporary hemostasis can be achieved with the application of pressure or hemostatic agents, but more definitive treatment may be needed to ensure bleeding will not resume once the patient is awake and normotensive. (1 , 2) Actively bleeding vessels encountered during maxillofacial surgery may be inaccessible, and vessels may recoil into bone, sometimes preventing definitive ligation. These scenarios may require ligation of the common carotid artery. (1) The purpose of this paper is to describe how to perform ligation of the common carotid artery in a step-by-step fashion. Both temporary and permanent ligation techniques are described.

    Scrivani, Steven J; Spierings, Egilius L H

    2016-08-01

    Pain in the orofacial region is a common presenting symptom. The majority of symptoms are related to dental disease and the cause can readily be established, the problem dealt with, and the pain eliminated. However, pain may persist and defy attempts at treatment. Intractable oral or facial pain can be diagnostically challenging. To make a definitive diagnosis and initiate proper treatment, a rigorous protocol for evaluation includes a thorough history and an appropriate comprehensive clinical examination and diagnostic testing, including chief complaint, history of present illness, medical history, physical examination, diagnostic studies, including imaging, and psychosocial evaluation.

  10. Portfolio: a comprehensive method of assessment for postgraduates in oral and maxillofacial surgery.

    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.

    Lymph node density is defined as the number of positive lymph nodes per total number of excised lymph nodes. In oral and maxillofacial cancer, there are recent data showing that increased lymph node density leads to worse outcomes for patients. However, data correlating lymph node density with other known risk parameters are lacking. This study investigated whether a direct correlation exists among cervical lymph node density, depth of invasion, perineural invasion, and extracapsular tumor spread. A retrospective chart review was undertaken to include all patients who underwent neck dissection with resection of primary oral and maxillofacial squamous cell carcinoma from January 2009 through July 2014. After applying the exclusion criteria, 286 patients were identified. Primary tumor depth of invasion, perineural invasion, and lymph node status, including extracapsular spread, were obtained from the standard pathology report. Descriptive statistics were applied. The association between 2 continuous tumor characteristics was summarized with the Pearson correlation coefficient, and the association between a continuous and a binary tumor characteristic was summarized with 2-sample t test. Statistical significance for the study was set at a P value less than .05. Mean age at time of surgery was 63.9 ± 12.5 years. The final study included 169 men and 117 women (N = 286). The mean depth of invasion was 12.3 ± 11 mm (range, 1 to 69 mm). Mean lymph node density was 0.04 ± 0.1 (range, 0 to 0.81). There was a positive association between lymph node density and depth of tumor invasion (Pearson correlation coefficient, r = 0.21; P negative; P negative; P correlated with other known prognostic features that lead to poor outcomes. Lymph node density could be an important feature to capture in future prospective trials. Pathology standards would be crucial in this endeavor.

    Aim of this study was to survey the knowledge, attitude and awareness of the subject of oral and maxillofacial surgery speciality amongst the consultants and practitioners of medicine in district of Vadodara. List of members of various specialities in medical faculty were obtained from Indian Medical Association, Baroda branch and staff members of medical colleges of Vadodara district. A questionnaire survey was made which was distributed and their options were noted. Surgical removal of third molar, oral submucous fibrosis and implants were the problems where oral surgeons were preferred. For maxillofacial trauma plastic surgeons and orthopaedic surgeons were preferred than oral surgeons. For maxillofacial pathology E.N.T surgeons were mostly preferred. There is low awareness regarding oral and maxillofacial surgery amongst the general practitioners and medical consultants in Vadodara district. Survey shows that our training needs to be upgraded and revamped so that our trainees (post graduates in oral surgery) and have a greater "hands-on" exposure during their postgraduate training. They will then be able to handle increasingly complex cases in a multispecialty setup when they graduate and earn the mutual respect of the medical and dental fraternity and also the general public. MBBS students during their dental postings should be made aware of the depth and scope of oral surgery branch.

    Every general dental practitioner and oral and maxillofacial surgeon needs a thorough knowledge of the diagnosis and management of medical emergencies. Cardiopulmonary arrest is the most urgent of emergencies and diagnosis must be done as soon as possible. This paper discusses the importance of the International Liaison Committee on Resuscitation which forms the guidelines for cardiopulmonary resuscitation (CPR), highlighting the important changes in the guidelines of CPR from the year 2000 to 2010, the basic sequence of performing CPR and also the role of defibrillation and the use of automated external defibrillators. Finally the five part chain of survival which is of utmost importance to dental health care professionals and oral and maxillofacial surgeons. All dental health care personnel and oral & maxillofacial surgeons should recognize the importance of the changes in the guidelines of CPR, be trained and allowed to use a properly maintained defibrillator, to respond to cardiac arrest victims.

    The purpose of this study was to develop a stent-based image guided surgery system and to apply it to oral and maxillofacial surgeries for anatomically complex sites. We devised a patient-specific stent for patient-to-image registration and navigation. Three dimensional positions of the reference probe and the tool probe were tracked by an optical camera system and the relative position of the handpiece drill tip to the reference probe was monitored continuously on the monitor of a PC. Using 8 landmarks for measuring accuracy, the spatial discrepancy between CT image coordinate and physical coordinate was calculated for testing the normality. The accuracy over 8 anatomical landmarks showed an overall mean of 0.56 {+-} 0.16 mm. The developed system was applied to a surgery for a vertical alveolar bone augmentation in right mandibular posterior area and possible interior alveolar nerve injury case of an impacted third molar. The developed system provided continuous monitoring of invisible anatomical structures during operation and 3D information for operation sites. The clinical challenge showed sufficient accuracy and availability of anatomically complex operation sites. The developed system showed sufficient accuracy and availability in oral and maxillofacial surgeries for anatomically complex sites.

    There may be significant variation amongst oral and maxillofacial surgeons (OMFS) in the identification and placement of cephalometric landmarks for orthognathic surgery, and this could impact upon the surgical plan and final treatment outcome. In an effort to assess this variability, 10 lateral cephalometric radiographs were selected for evaluation by 16 OMFS with different levels of surgical knowledge and experience, and the position of 21 commonly used cephalometric landmarks were identified on radiographs displayed on a computer screen using a computer mouse on a pen tablet. The database consisted of real position measurements (x, y) to determine the consistency of landmark identification between surgeons and within individual surgeons. Inter-examiner analysis demonstrated that most landmark points had excellent reliability (intra-class correlation coefficient >0.90). Regardless of the level of surgeon experience, certain landmarks presented consistently poor reliability, and intra-examiner reliability analysis demonstrated that some locations had a higher average difference for both x and y axes. In particular, porion, condylion, and gonion showed poor agreement and reliability between examiners. The identification of most landmarks showed some inconsistencies within different parameters of evaluation. Such variability among surgeons may be addressed by the consistent use of high-quality images, and also by periodic surgeon education of the definition of the specific landmarks.

    Full Text Available Abstract Background Laser surgery lacks haptic feedback, which is accompanied by the risk of iatrogenic nerve damage. It was the aim of this study to investigate diffuse reflectance spectroscopy for tissue differentiation as the base of a feedback control system to enhance nerve preservation in oral and maxillofacial laser surgery. Methods Diffuse reflectance spectra of nerve tissue, salivary gland and bone (8640 spectra of the mid-facial region of ex vivo domestic pigs were acquired in the wavelength range of 350-650 nm. Tissue differentiation was performed using principal component (PC analysis followed by linear discriminant analysis (LDA. Specificity and sensitivity were calculated using receiver operating characteristic (ROC analysis and the area under curve (AUC. Results Five PCs were found to be adequate for tissue differentiation with diffuse reflectance spectra using LDA. Nerve tissue could be differed from bone as well as from salivary gland with AUC results of greater than 88%, sensitivity of greater than 83% and specificity in excess of 78%. Conclusions Diffuse reflectance spectroscopy is an adequate technique for nerve identification in the vicinity of bone and salivary gland. The results set the basis for a feedback system to prevent iatrogenic nerve damage when performing oral and maxillofacial laser surgery.

    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.

    Thirty-two cases of sarcomas involving the oral and maxillofacial region over a period of 25 years were reviewed. The age range was from 5 months to 77 years with a mean age of 42. The male to female ratio was 3:1. The sarcomas were located in the maxilla including the maxillary sinus (n= 13), mandible (n= 13), buccal mucosa (n= 3), temporomandibular fossa (n= 2), and submandibular region (n= 1). Histologically sarcomas were classified as osteosarcoma (n= 9), malignant fibrous histiocytoma (n= 7), rhabdomyosarcoma (n= 5), fibrosarcoma (n= 3), plasmacytoma (n= 2), leiomyosarcoma (n= 2), angiosarcoma (n= 2), liposarcoma (n= 1), and ameloblastic fibrosarcoma (n= 1). Surgical resection was performed in 29 cases. Local recurrence was found in 10 patients and metastasis in 11 patients. Metastases included five regional lymph node metastases and eight distant metastases. The survival of patients with local recurrence or metastasis was poor. Surgery is the most reliable treatment for sarcomas of the oral and maxillofacial region. Adequate excision with safety surgical margin as the initial therapy is important for better survival. The value of radiation therapy and/or chemotherapy is uncertain. The 5-year survival rate of primary cases was 61%.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions The two tested simulation methods were well accepted and most

    To investigate the attitudes of maxillofacial surgeons in the treatment and dental rehabilitation of oral cancer patients in the UK. The survey was conducted by postal questionnaires with 17 close-ended questions. A total of 229 questionnaires were sent to members of the British Association of Oral and Maxillofacial Surgeons over a one week period. A follow-up was sent if a reply was not received within 12 weeks. These results were compared to a similar study that was carried out approximately 15 years ago. The response rate was 65.5% (150/229). Overall 62% of respondents (92/150) carried out maxillary resections, which represents a decline of 23% on the previous study. There has been an increase in surgeons reconstructing the maxillary defect from 38% in the 1995 study to 91% in the present study. Ninety-eight percent of respondents had their patients seen in a multidisciplinary team (MDT) clinic, but in only 30% of the cases was a restorative dentist present on these clinics. There has been an improvement in the accessibility of a restorative dentist for this patient cohort, from 65% to 90%. The use of implants for dental rehabilitation post-cancer surgery has increased from 43% to 93%. This study highlights the changes in the dental and oral rehabilitation of patients undergoing resective surgery for oral cancer and especially those undergoing a maxillectomy procedure. It illustrates the increased use of implants for post-surgery rehabilitation and shows the different trends in which these implants are placed. An important aspect of this study is the input of the dental team. Current national guidelines state that a consultant restorative dentist needs to be a member of the MDT; this survey shows that this was the case in only 30% of responses.

    Full Text Available Introduction: Oral and maxillofacial malignancies (OMMs consist of a wide range of lesions, which constitute varying proportions of the total incidence of malignancies in the human population. Available epidemiological data vary across racial, geographical, gender, and occupational divides. They are often associated with significant impairment of patients' quality of life. Materials and Methods: A review of hospital records of patients with histologically diagnosed primary OMM, who presented to the Department of Dental and Maxillofacial Surgery, Usmanu Danfodiyo University Teaching Hospital, over a 5-year period, was done. Data including age, gender, site, and type of tumor, and histological grade of tumor were retrieved and analyzed with the SPSS version 20.0. Results: A total of 77 cases of OMMs were identified with a male/female ratio of 1:1.03. The mean (±standard deviation age was 50.1 (17.8 years. Squamous cell carcinoma was the most frequently seen epithelial malignancy constituting 35.1% of all malignancies, with most patients in advanced stages of the disease. Osteosarcoma was the most frequently diagnosed sarcoma, constituting 11.7% of all malignancies seen. Salivary gland malignancies constituted 29 (37.7%. Other malignancies seen include, malignant peripheral nerve sheath tumor, leiomyosarcoma, and malignant melanoma. Conclusion: OMMs constitute a significant health burden in our region. Thus, adequate resources should be allocated toward improving awareness among the populace. Policy shifts and regular dental visits which may increase the likelihood of early intervention should be instituted.

    Full Text Available Introduction: The accidents of motorcyclists constitute a growing cause of dead and injuries in the cities being most of them attack if they are fulfilled the effective traffic norms and it is used a helmet of facial protection appropriately. Objective: The main objective of the investigation is the relationship that exists among fractures of the maxillofacial area and the use of a helmet adapted in motorcyclists in the city of Cali to settle down. Study design: We design a prospective study gathering the information in the emergency rooms of the University Hospitals of the Valley, San Juan of God and Clinical Rafael Uribe Uribe of the city of Cali, Colombia. The period of the study was of one year with a field work carried out among November from 2.001 to June of 2.002. The statistical package EPIINFO version was used 6.04. Results and conclusion: The size of the sample belonged to 108 people, 88 men (81.5% and 20 women (18.5%. The most important conclusion in this investigation is that most (57=52.8% of the motorcyclists that had fractures they didn’t use helmet in the moment of the collision, and that the 51 motorcyclists that if they used it, only 3 (5.8% they used a helmet that fulfills the effective norms and that he/she allows to give appropriate protection to the user. It is for this reason that the causes should be investigated of the why don’t use of a helmet adapted in uneven motorcyclists to implement massive campaigns directed to counteract this behavior with the purpose of diminishing remarkable.

    There are many similarities between flying commercial aircraft and surgery, particularly in relation to minimising risk, and managing potentially fatal or catastrophic complications, or both. Since 1979, the development of Crew Resource Management (CRM) has improved air safety significantly by reducing human factors that are responsible for error. Similar developments in the operating theatre have, to a certain extent, lagged behind aviation, and it is well recognised that we can learn much from the industry. An increasing number of publications on aviation factors relate to surgery but to our knowledge there is a lack of research in our own specialty. We discuss how aviation principles related to human factors can be translated to the operating theatre to improve teamwork and safety for patients. Clinical research is clearly needed to develop this fascinating area more fully. Copyright © 2011 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    Increasing numbers of medics are applying to dental school to pursue a career in oral and maxillofacial surgery (OMFS), particularly in the aftermath of Modernising Medical Careers (MMC), but their perspectives, experience, and training up to this point differ widely. We aimed to characterise these differences in the light of MMC and beyond by doing a survey of 20 dentists and 24 medics who were applying for their second degree. They were questioned about factors that influenced their choice of career and university, the motivation to pursue specialty training, and were asked for their opinions on suggested measures for workforce planning. The medics were subdivided into those who had trained before MMC (n=18), and those who had not (n=6). Dentists had considerably more OMFS experience than medics (mean 22 months compared with 4.2 months), and 46% (11/24) of medics had no substantive OMFS experience. Of those who had trained before MMC 3/18 considered OMFS as their first choice of career, compared with 4/6 who have trained since, and 15/20 of dentists. Eighty-three percent (20/24) of medics admitted that MMC had influenced their choice of career, and 54% (13/24) had applied for training in a specialty other than OMFS, notably otolaryngology. The most favoured method of workforce planning among all respondents (25/44) was "roughly matching" places on a second degree to projected OMFS training posts.

    The purpose of this article is to describe the process of transitioning a traditional face-to-face oral and maxillofacial radiology (OMR) lecture course to a case-based, team-based learning model for students ready to enter their fourth and final year of dental school. Data were collected from 294 new fourth-year students (Classes of 2009, 2010, and 2011) who participated in the newly formatted OMR course. At the time the course was taken, students had completed one year of clinical experience in taking and evaluating radiographic images on patients with various clinical conditions. Each class of approximately 100 students was divided into ten teams of ten each, and a topic on oral and maxillofacial lesions was assigned to each team. The teams researched their assigned topics, created PowerPoint presentations, and posted them on the course management system Blackboard site. The instructor posted on Blackboard eight to ten cases representing various lesions on that topic. Minimal clinical history was released at that point. Students reviewed the teams' PowerPoint presentations and the cases, answered the questions for each case, and turned in written assignments to be graded. The diagnoses were discussed in class. An end-of-course survey found that 71 percent of the students felt the case-based instruction helped them learn the content in a more comprehensive manner and 77 percent felt the in-class discussion increased their knowledge of radiographic interpretation. Some students said they felt uncomfortable being called on randomly during the class discussion. National Board Dental Examination results for the classes of 2009 and 2010 showed slight improvement when compared to national scores. As a result of student feedback, the course continues to be offered in the case-based, team-based format.

    In polymorbid or anaemic patients who receive preoperative radiotherapy or undergo long duration surgery involving potentially infectious sites, perioperative antibiotic prophylaxis (PAP) that is effective against normal oral bacterial flora is mandatory and plays an important role in preventing postoperative infection. In a four-year retrospective analysis, the incidence, outcome, and the efficacy of PAP were evaluated in patients treated at the Department of Oral and Maxillofacial Surgery and Otorhinolaryngology at Kecskemét Hospital. The results were compared with data from the literature to determine if the use of PAP was adequate at the Department.During the study period (between 01/09/2007 and 31/01/2011) 108 patients were evaluated. The mean duration of prophylactic antibiotic treatment was 8.3 ± 5.2 days, with cefotaxime+metronidazole being the most commonly used combination. Surgical site infection occurred in 8 patients (7.5%) in the clean-contaminated category.Our results showed that the perioperative antibiotic prophylaxis administered at our Department was efficient and effective against the oral bacterial flora of patients. Its use is recommended in head and neck microsurgery. To avoid development of antibiotic resistance and to reduce costs, it seems that the duration of antibiotic regimen for primary surgery can be reduced from 8.3 ± 5.2 days to 3 days.

    To evaluate the accessibility to editorial information in Oral & Maxillofacial Surgery journals. A cross-sectional study using the WOS-Web of Science database in three categories: "Surgery," "Otorhinolaryngology," and "Dentistry, Oral Surgery & Medicine" was designed. Journals were filtered by title and classified under three headings: OMFS specialty; OMFS subspecialty and related sciences; and multidisciplinary journals. Specialty scope (OMFS vs. other); impact factor; path for the manuscript; blinding policy; accessibility to reviewers' criteria; and percentage of acceptance. Only 46 of 330 journals met the inclusion criteria. All OMFS journals provided comprehensive information about the review process, compared to 5 of 27 (18.5%) of Oral Surgery and related sciences periodicals. Most specialty journals do not inform about the blind review mode used (20 of 33; 60.6%). Generally, information about the reviewers' assessment criteria is scarce, but is available from all OMFS journals, which also state the percentage of manuscript acceptance (100% vs. 14.8%). OMFS JCR journals provide adequate information about their editorial process in terms of path for the manuscript, accessibility to reviewers' criteria, and percentage of acceptance. Additional efforts are needed to increase accessibility to information about blinding policy and average time from submission to acceptance.

    The use of the Carbon dioxide Laser to perform surgical procedures in the oral cavity has been described as a successful method for the treatment of several conditions affecting the maxillofacial region. Several benefits of the use of the CO2 Laser have been reported and includes reduction of postoperative pain and edema, local hemosthasis, reduction of scaring and wound contraction and infection. The aim of this work is to present our clinical experience in performing several surgical procedures using the CO2 Laser to treat soft tissue pathologies of both benign and malign origin as well as on performing pre-prosthetic surgery, apical surgery and on the treatment of pre-malignancies. Our experience demonstrate that the use of the Carbon dioxide Laser in treating oral soft-tissue pathology presents advantages over conventional techniques and local discomfort and pain are the most common complaints after Laser surgery. The Carbon dioxide Laser does not offer any enhanced cure-rate for oral pathology, but rather it is a precise means of removing soft tissue lesions with little upset afterwards.

    Objectives The aim of this study was to determine the level of evidence that is published in the oral and maxillofacial radiology (OMR) literature. Methods OMR papers published in Dentomaxillofacial Radiology and Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology between 1996 and 2005 were classified using epidemiological study design and diagnostic efficacy hierarchies. The country of origin and number of authors were noted. Results Of the 725 articles, 384 could be classified with the epidemiological study design hierarchy: 155 (40%) case reports/series and 207 (54%) cross-sectional studies. The distribution of study designs was not statistically significant across time (Fisher's exact test, P = 0.06) or regions (P = 0.89). The diagnostic efficacy hierarchy was applicable to 246 articles: 71 (29%) technical efficacy and 166 (67%) diagnostic accuracy studies. The distribution of efficacy levels was not statistically significant across time (P = 0.22) but was significant across regions (P < 0.01). Authors from Japan produced 26% of the papers with a mean ± standard deviation of 5.78 ± 1.98 authors per paper (APP); American authors, 23% (3.78 ± 1.72 APP); and all others, 51% (3.76 ± 1.51 APP). Conclusion The OMR literature consisted mostly of case reports/series, cross-sectional, technical efficacy and diagnostic accuracy studies. Such studies do not provide strong evidence for clinical decision making nor do they address the impact of diagnostic imaging on patient care. More studies at the higher end of the study design and efficacy hierarchies are needed in order to make wise choices regarding clinical decisions and resource allocations. PMID:21697152

    Introduction: Radiofrequency ablation (RFA) refers to a high-frequency current that heats and coagulates tissue. In the standard RFA setup, three components are used: a generator, an active electrode, and a dispersive electrode. RFA has garnered support in many of the surgical fields as an alternative to traditional procedures used in tumor removal. Other methods can prove to be more invasive and disfiguring to the patient, in addition to the unwarranted side effects; however, RFA provides a more localized treatment, resulting in decreased co-morbidity to the patient. Currently, its use in the field of oral and maxillofacial surgery is limited, as its technology has not reached our field. By describing its limited use to the optics community, we hope to expand its uses and provide patients with one more alternative treatment option. Methods and Uses: We will describe the use of RFA on three types of pathology: lymphangioma, rhabdomyoscarcoma, oral squamous cell carcinoma, and neoplastic osseous metastasis. The majority of treatments geared towards these pathologies involve surgical resection, followed by reconstruction. However, damage to vital structures coupled with esthetic disfigurement makes RFA a more valuable alternative. In many of the cases, the tumors were successfully removed without recurrence. Conclusion: While the use of RFA has been scarce in our field, we believe that with more exposure it can gain momentum as an alternative to current treatment options. However, there are improvements that we feel can be made, helping to maximize its effectiveness.

    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.

    Temporomandibular joint disorders (TMJD) are the most common debilitating conditions of the stomatognathic system. Although they exist in the community they are not mentioned in the literature as an endemic health problem. Their prevalence does not seem to be clear enough for the health system in Tanzania to give them priority as other health problems.

    The purpose of this study was to evaluate the level of confidence that senior-level oral and maxillofacial surgery (OMS) residents have in the management of temporomandibular joint (TMJ) disorders, determine their exposure to various invasive TMJ procedures during training, and assess their confidence in performing those procedures on completion of residency. A questionnaire was designed, and a link to a University of Illinois at Chicago Qualtrics Survey platform (Qualtrics, Provo, UT) was e-mailed to all program directors at Commission on Dental Accreditation-accredited OMS training programs in the United States. The program directors were asked to forward the 20-multiple-choice question anonymous survey to their senior-level residents for completion. The survey included the program's demographic characteristics, resident's confidence in assessing and managing patients with temporomandibular disorders (TMDs), resident's experience performing various invasive TMJ procedures, and whether the resident believed he or she had received sufficient education and clinical experience in the management of TMJ disorders. The data were collected and summarized by use of a standard spreadsheet analysis, as well as appropriate descriptive and analytical statistical tests. The response rate was 28.0%. Of the 56 respondents, 52 (92.9%) reported having received instruction in nonsurgical management of TMDs. All respondents confirmed that invasive TMJ procedures were performed in their program. The most commonly performed procedure was TMJ arthrocentesis (mean rating, 3.11), followed by open TMJ surgery (mean rating, 2.82). The least-performed invasive surgical procedure was autogenous total TMJ replacement surgery (mean rating, 1.39). Eighty percent of residents reported being comfortable managing the TMD patient. The only procedure with which the respondents were highly confident was TMJ arthrocentesis (mean rating, 3.89). This study suggests that confidence levels in the

    Background Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. Material and Methods The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. Results 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT, 1case of DVT and PE. The mean age of these patients was 62.07 years. Reconstruction was performed in 12 patients of these cases, most of which were diagnosed as malignance. Mean length of surgery was 8.74 hours, and lower extremity deep venous cannula (DVC) was performed in all these patients. Conclusions We analyzed several characters of oral and maxillofacial surgery and suggested pay attention to lower extremity DVC which had a high correlation with DVT according to our data. Key words:Venous thromboembolism, pulmonary embolism, deep vein thrombosis, oral and maxillofacial surgery. PMID:27918738

    One hundred years ago the Great War, also known as the first world war, started. Historians consider the attack on the Austrian Archduke Franz Ferdinand on June 18, 1914 as the cause of the catastrophe. The initial war of movement turned into a 'Sitz Krieg', trench warfare. Many hundreds of thousands of military casualties were treated for a wide variety of facial wounds that resulted from the conflict. The origin of the specialisation oralmaxillofacial surgery is considered to be a consequence of these treatments. Several treatments dating from the first world war are still in use, such as the application of the 'dental splint' in fracture treatment, intra-oral transposition flaps for sealing small injuries and bone transplants from the iliac crest to restore defects of the jaw. In the Netherlands, which was neutral, experiences from the Great War were retained by the appointment in 1919 of a Lecturer in Oral Diagnosis and Oral Surgery at the University of Utrecht.

    Oral and maxillofacial surgery has not been benefitting from image guidance techniques owing to the limitations in image registration. A real-time markerless image registration method is proposed by integrating a shape matching method into a 2D tracking framework. The image registration is performed by matching the patient's teeth model with intraoperative video to obtain its pose. The resulting pose is used to overlay relevant models from the same CT space on the camera video for augmented reality. The proposed system was evaluated on mandible/maxilla phantoms, a volunteer and clinical data. Experimental results show that the target overlay error is about 1 mm, and the frame rate of registration update yields 3-5 frames per second with a 4 K camera. The significance of this work lies in its simplicity in clinical setting and the seamless integration into the current medical procedure with satisfactory response time and overlay accuracy.

    A key aspect of recruiting and retaining the best trainees is identification of the factors that attracted them to OMFS. Although such factors have been examined for medicine in general, we know of no previous study that has looked at those that are specific to OMFS. We distributed a survey online to roughly 1500 people who had registered an interest in OMFS over the past seven years. Personal data, and those about education and employment, were recorded, together with particular factors that drew them to OMFS. Of the 251 trainees who responded, 177 (71%) were interested in a career in OMFS. Differences among sub-groups related to dual qualification, sex, and relationships. Open comments identified the following attractive factors: variety of work, intellectually interesting work, collegiate atmosphere within OMFS, and making a difference to patients. The personalities of those who continued with OMFS training placed high value on achievement, and were more conscientious. The factors identified suggest that the positioning of OMFS as a complex, challenging, and varied hospital-based surgical specialty is key to attracting trainees, and these will be used in future research so that we can move forward from identifying preferences to assessing the relative value placed on those preferences. The data will be useful in the development of strategies to attract new trainees and retain them in the specialty. Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons.

    Full Text Available Abstract Background The aim of this study was to evaluate the ability of oral/maxillofacial surgeons (OMFSs and orthodontists to predict third molar eruption by examining a simple panoramic radiograph in cases where full spontaneous eruption occurred. Methods Panoramic radiographs of 17 patients, 13–16 years of age, were obtained just after orthodontic treatment (T1, when the third molars were intraosseous. The radiographs at T1 were presented to 28 OMFSs and 28 orthodontists—who were asked to give a prognosis for the lower third molars on both sides (n = 34. The full spontaneous eruption of all third molars was clinically observed when patients were older than 18 years (T2. These teeth were clinically asymptomatic at T1 and T2. Results OMFSs decided by extractions in 49.6 % of cases while orthodontists in 37.8 % (p < 0.001, when the radiographs were examined at T1. Agreement between OMFSs and orthodontists was excellent (Kappa = 0.76, p < 0.0001, as well as intragroup agreement for both OMFSs (Kappa = 0.83 and orthodontists (Kappa = 0.96. Conclusions Despite a remarkable agreement for third molar prognosis, orthodontists and OMFSs were unable to predict lower third molar eruption by examining a simple panoramic radiograph. Both indicated extractions of a considerable number of spontaneously erupted asymptomatic teeth.

    2013-10-01

    Most dental foundation year 2 (DF2) training takes place in oral and maxillofacial surgery (OMFS) units. We did a survey of DF2 trainees in these units by telephone interviews and an online questionnaire to find out about their experience of training and their career aspirations. A total of 123 responded, which is roughly 41% of the total estimated number of trainees. Trainees applied for these posts mainly to improve their dentoalveolar skills (50%), and this was cited as the best aspect of the training. Most (81%) were on-call at night and this was generally thought to be a valuable training experience (77%), but 20% thought that it was the worst aspect of the job. Most did not regret taking up the post although the experience had caused 75% to alter their intentions about their future career; general dental practice was the commonest choice. In conclusion, trainees are generally satisfied with their training and these positions have guided their choices about future careers.

    It is estimated that, in the United States, more than 40,000 patients are injured each day because of preventable medical errors. Although numerous studies examine the causes of medical trainee errors and efforts to mitigate patient injuries in this population, little research exists on adverse events experienced by oral and maxillofacial surgery (OMFS) residents or strategies to improve patient safety awareness in OMFS residency programs. The authors conducted a retrospective literature review of contemporary studies on medical trainees' reported risk exposure and the impact of integrating evidence-based patient safety training into residency curricula. A review of the literature suggests that OMFS residents face similar risks as medical trainees in medical, surgical, and anesthesia residency programs and may benefit from integrating competency-based safety training in the OMFS residency curriculum. OMFS trainees face particular challenges when transitioning from dental student to surgical resident, particularly related to their limited clinical exposure to high-reliability organizations, which may place them at higher risk than other medical trainees. OMFS educators should establish resident competence in patient safety principles and system improvement strategies throughout the training period.

    A faculty shortage crisis exists in oral and maxillofacial surgery (OMS) education affecting dental students, OMS residents, and OMS full-time faculty. This report was designed to help nonacademic OMS practitioners better understand the problem and appreciate the potential benefits of volunteering as a part-time faculty member. Volunteer part-time faculty can help bolster the efforts of the faculty leaders (full-time and part-time) by taking on some of the dental student and/or resident educational responsibilities. They can also help free up some of the full-time faculty members' time to allow them to complete the scholarly activities required of full-time academicians. Volunteer part-time faculty can greatly benefit from their involvement in dental education. Exposure to faculty leaders and dental students and residents can be educationally enriching and stimulating for volunteer part-time faculty. Students and residents will benefit from learning the differing approaches to patient management that volunteer part-time faculty can provide. In addition, volunteer part-time faculty can have a scope of practice or practice emphasis that differs from and complements that of the faculty leaders. Finally, residents can also benefit from exposure to private practice management strategies that volunteer part-time faculty share. The present report explores how all parties can benefit from OMS faculty volunteerism.

    300 cases of non-melanoma cutaneous lesion procedures carried out by the Oral and Maxillofacial Surgery and Dermatology departments in a North West London hospital over a 6 month period between September 2011 and February 2012 were included in a retrospective case control study. The results from each speciality were compared. The mean age of the OMFS group was 75.8 years compared to 69.9 years in the dermatology group. There was no statistically significant difference in gender between the 2 groups. The OMFS group treated a higher proportion of atypical (17%) and malignant (64.9%) cases compared to the dermatology group (11.3% and 50.5% respectively). This could also account for the fact that the OMFS group carried out a higher number of full excisions compared to dermatology. Both groups had a similar number of false positives (a benign lesion initially diagnosed as malignant) and a similar proportion of false negatives (a malignant lesion initially diagnosed as benign). Overall, the results show that both specialities had similar outcomes when managing non-melanoma cutaneous lesions. Both groups adhere to the guidelines set out by the British Association of Dermatologists and the National Institute of Clinical Excellence when managing such lesions.

    To determine prevalence, distribution, and associated factors of maxillofacial fractures (MFs) among third-party insurance plan patients. A cross-sectional and descriptive study with data of patients from Oral and Maxilofacial Surgery Department (January 1994 to December-1999) at the Instituto Mexicano del Seguro Social in Campeche, Mexico, was carried out. Daily registries, surgical programming lists' and charts of 1,611 patients were used to determine presence of MFs, age, sex, and status of the insured. Analysis was made in STATA 7 using X2. Odds ratio (OR) with confidence intervals to 95% were calculated (1C95%). The prevalence of MFs was 9.4%. The age average was 31.04+/-15.49 years old. The major percentage of MFs were dentoalveolar fractures (26.3%), followed by mandibular angle (20.4%) and mandibular body (13.2%). Being a male was strongly associated with presence of MFs (OR=6.1; 1C95% 4.08, 9.12). The groups of age with greater association to MFs were those of 41-50 (RM=3.30 1C95% 1.57, 6.96) and those of 31-40 (RM=2.87 1C95% 1.53, 5.55). The workers category displayed a superior association (RM=6.25 1C95% 3.21, 13.56) to the other groups of the insured category. The epidemiologic characteristics of MFs were similar to those reported in the specialized literature. Appearing mainly in men and intermediate age groups ages. The patterns of fractures in the studied patients were different according to the age group to which they belonged.

    This study was designed to evaluate the variations in decision making among Brazilian oral and maxillofacial surgeons (OMFS) and trainees in relation to third molar surgery. A survey on 18 diverse clinical situations related to the assessment and treatment of the third molar surgeries was conducted during the 20th Brazilian National OMFS meeting. Participants were divided into three groups according to their level of training. Another variable studied was length of experience. Correlation between the question answers and the variables was analysed using the chi-square test and the f test. The mean age of participants was 32.68 years, and their mean length of experience was 5.24 years. There were no statistical differences between the level of training and number of years of experience and the responses to 15 of the 18 questions on clinical situations. However, differences were found in responses to prophylactic extraction of asymptomatic third molars, use of non-steriodal anti-inflammatory drugs (NSAIDs) during the preoperative surgical period and the use of additional imaging to plan extractions. The group with shorter time of experience (3.8 ± 3.94 years) tended to recommend extractions of asymptomatic third molars more frequently compared with the more experienced surgeons (P = 0.041). More experienced surgeons used NSAIDs in the preoperative surgical period, whereas the majority of the youngest surgeons (4.1 ± 5.96 years of experience) did not (P = 0.0042). The certificated trained and in practice group tended to treat deep lower third molar impactions based on the findings of a panoramic radiograph, without obtaining additional imaging [cone beam computed tomography (CBCT)] before treatment (P = 0.0132). Decision making regarding third molar treatment differs according to the level of training and is influenced by the number of years of experience. Therefore, further continuous education programmes in this area are warranted to make recommendations regarding

    Full Text Available Abstract Background The etiology of maxillofacial injuries varies from one country to another and even within the same country depending on the prevailing socioeconomic, cultural and environmental factors. Periodic verification of the etiology of maxillofacial injuries helps to recommend ways in which maxillofacial injuries can be averted. The aim of the present study is therefore to analyse the characteristics and trends of maxillofacial injuries in Nigeria based on a systematic review of the literature. Methods A literature search using MEDLINE was conducted for publications on maxillofacial injuries in Nigeria. The relevant references in these publications were manually searched for additional non-Medline articles or abstracts. Forty-two studies met the inclusion criteria and the full-texts of these articles were thoroughly examined. Due to lack of uniformity and consistency in assessment and measurement variables, and treatment modalities in most of the studies, it was impossible to apply the traditional methods of a systematic review. Therefore, a narrative approach was conducted to report the findings of the included studies. Results Although, other causes like assaults, sport injuries, and industrial accidents increased in numbers, throughout the period between 1965 and 2003, road traffic crashes remained the major etiological factor of maxillofacial injuries in all regions, except northeastern region where assault was the major cause. A significant increase in motorcycles related maxillofacial injuries was observed in most urban and suburban centres of the country. Animal attacks were not an unusual cause of maxillofacial injuries in most parts of northern Nigeria. Patients in the age group of 21–30 years were mostly involved. A strong tendency toward an equal male-to-female ratio was observed between earlier and later periods. Conclusion Road traffic crashes remain the major cause of maxillofacial injuries in Nigeria, unlike in most

    Full Text Available Purpose: The aim was to understand dental students’ experiences with oral and maxillofacial surgery (OMS teaching, their confidence levels in performing routine dento-alveolar operations, and the relationship between the students’ confidence level and the number of teeth extracted during the clinical practice. Methods: The survey questionnaire was distributed to 32 students at Aljouf University College of Dentistry, Saudi Arabia during their fourth and fifth year in 2015. Respondents were asked to rate 19 items, which represent a student’s confidence in performing routine surgical interventions, using a four-point Likert scale (1=very little confidence, 4=very confident. A multivariate regression was computed between average confidence and the variables: weekly hours devoted to studying oral and maxillofacial surgery, college grade point average, and the total number of teeth extracted. Results: The response rate was 100%. Students revealed the highest level of confidence in giving local anesthesia (96.9%, understanding extraction indications (93.8%, and performing simple extractions (90.6%. Less confidence was shown with handling difficult extractions (50.0%, extracting molars with separation (50.0% or extracting third molars (56.3%. The average confidence in performing surgical procedures was 2.88 (SD=0.55, ranging from 1.79 to 3.89. A given student’s confidence increased with an increase in the total number of teeth extracted (P=0.003. Conclusion: It reveals a significant impact of undergraduate clinical training on students’ confidence in performing oral and maxillofacial surgery clinical procedures: The more clinical experience the students had, the more confidence they reported.

    Regenerative medicine is an emerging field of biotechnology that combines various aspects of medicine, cell and molecular biology, materials science and bioengineering in order to regenerate, repair or replace tissues. The oral surgery and maxillofacial surgery have a role in the treatment of traumatic or degenerative diseases that lead to a tissue loss: frequently, to rehabilitate these minuses, you should use techniques that have been improved over time. Since 1990, we started with the use of growth factors and platelet concentrates in oral and maxillofacial surgery; in the following period we start to use biomaterials, as well as several type of scaffolds and autologous tissues. The frontier of regenerative medicine nowadays is represented by the mesenchymal stem cells (MSCs): overcoming the ethical problems thanks to the use of mesenchymal stem cells from adult patient, and with the increasingly sophisticated technology to support their manipulation, MSCs are undoubtedly the future of medicine regenerative and they are showing perspectives unimaginable just a few years ago. Most recent studies are aimed to tissues regeneration using MSCs taken from sites that are even more accessible and rich in stem cells: the oral cavity turned out to be an important source of MSCs with the advantage to be easily accessible to the surgeon, thus avoiding to increase the morbidity of the patient. The future is the regeneration of whole organs or biological systems consisting of many different tissues, starting from an initial stem cell line, perhaps using innovative scaffolds together with the nano-engineering of biological tissues.

It is difficult to diagnose the exact cause of post-operative psychosis. We report three cases, which developed psychosis post-operatively after undergoing major oral and maxillofacial surgeries. All the three patients were administered dexamethasone peri-operatively. Dexamethasone is used to prevent or reduce post-operative edema. The exact dose of dexamethasone, which can cause psychosis, is unknown. It is important to raise awareness about this potential complication so that measures for management can be put in place in anticipation of such an event.

    Commonly occurring extensive osseous defects in the oral and maxillofacial area are seen following complete or partial resection of the mandible and other facial bones in oncologic surgery or following traumatic injury. Autogenous osseous grafts have been used to restore these defects. Additionally, bone graft substitute materials and autogenous osseous grafts are applied to congenital defects such as cleft palate, facial clefts, and facial asymmetry. We have simulated these types of defects in appropriately aged Macaca fascicularis and Macaca mulatta monkeys to study the efficacy of using bone morphogenetic protein (BMP) as an osseous inductor. The objective of these studies was to obtain information on the feasibility of employing bone inductors to regenerate large continuity critical-sized maxillofacial defects without using bone grafts. In one study, involving eight animals, the body of the mandible was removed, simulating hemi-mandibulectomy defects following traumatic bone loss or oncologic surgery. Recombinant human (rh) BMP-2 (Genetics Institute, Cambridge, Massachusetts) in a collagen carrier (Colla-Tec Inc., Plainsboro, New Jersey) then was placed in the hemi-mandibulectomy defect with use of titanium orthopaedic mesh fixation (Sofamor Danek-Medtronic, Memphis, Tennessee). Entire bone regeneration of the defect was observed 5 and 6 months postoperatively. In another group of subhuman primates, the restored area was functionally stimulated at the 5-month post-BMP implantation level by placement of intraoral titanium implants. The animals were allowed to function for 8 months with these titanium implants. Microscopic results showed increased density, bone volume, and thickness of the trabecular bone pattern. The bone cortex in the restored defect also increased in thickness compared with the nonsurgical areas. To evaluate the effect of rhBMP-2 in aging individuals, a group of six Macaca animals over 20 years of age received the same type of mandibular

    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.

    Objectives The objective of this study was to compare the accuracy of contrast-enhanced CT (CECT) and contrast-enhanced MRI (CEMRI) in the detection of perineural spread (PNS) of adenoid cystic carcinoma (ACC) in the oral and maxillofacial regions. Methods This study consisted of 13 ACCs from 13 patients, all of which were histopathologically diagnosed. Both CECT and CEMRI were performed in all patients before the treatment. The images of each patient were retrospectively evaluated for the detection of PNS. The definitions of PNS included abnormal density/signal intensity, contrast enhancement or widening of the pterygopalatine fossa, palatine foramen, incisive canal, mandibular foramen and mandibular canal, and enlargement or excessive contrast enhancement of a nerve. Results 11 out of 13 cases were proven to exhibit PNS histopathologically. 8 of the 11 cases for which PNS was histopathologically proven exhibited PNS on MR images. Six of the eight cases for which PNS was exhibited on MR images also exhibited PNS on CT images. The sensitivity, specificity and accuracy for the detection of PNS were 55%, 100% and 62% on CT images and 73%, 100% and 77% on MR images, respectively. Although the accuracy of PNS on MR images was slightly superior to that on CT images, there were no statistically significant differences between the detection of PNS on CT images and on MR images. Conclusions CT and MR images are equally useful for the detection of PNS of ACC in the oral and maxillofacial regions. PMID:22301639

    2014-02-01

    The Internet is a powerful method of acquiring and sharing information. In marketing and business, online visibility is vital for publicity and the reputation of an organisation. To our knowledge, the importance of such visibility in medicine in general, and in Oral and Maxillofacial Surgery (OMFS) services in the UK, has not previously been investigated. We aimed to provide a better understanding of the way that patients use the Internet by asking 450 patients to complete a questionnaire when they attended outpatient OMFS departments at 2 centres. We also assessed the online visibility of the British Association of Oral and Maxillofacial Surgeons (BAOMS) and investigated the correlation between the strength of online visibility and professional reputation. Results from the self-administered, anonymous, validated questionnaires showed that 82% of patients agreed that the Internet was a powerful source of information, and two-thirds associated online visibility with a good reputation. However, the perceived online visibility of the BAOMS was poor (2%). This study mirrors findings in business publications, and confirms the link between online visibility and professional reputation. It also shows that there is a gap between patients' perceptions and the level of uptake of professional resources. We propose various strategies to bridge this gap and to promote the online visibility and professional reputation of the BAOMS and of OMFS services in the UK.

    The aims of this study were to determine whether male vs. female oral and maxillofacial surgery (OMS) residents, academic surgeons (i.e., faculty members), and private practitioners in the U.S. differed in their general career satisfaction and job/professional satisfaction. Survey data were collected in 2011-12 from 267 OMS residents (response rate 55%), 271 OMS academic surgeons (response rate 31%), and 417 OMS private practitioners (response rates 13% web-based survey and 29% postal mail survey). The results showed that while the male vs. female OMS private practitioners and academic surgeons did not differ in their career satisfaction, the female residents had a lower career satisfaction than the male residents (on four-point scale with 4=most satisfied: 3.03 vs. 3.65; pcareer, and were more likely to consider a career change in the next five years than the male residents. While these male and female oral and maxillofacial surgeons in private practice and academia did not differ in their career and job satisfaction, the male and female residents differed significantly, with female residents reporting a significantly poorer career and job satisfaction than male residents. Future research needs to explore ways to improve career and professional satisfaction of female OMS residents.

    Developments in oral and maxillofacial radiology affect almost every aspect of dentistry: some change the legal framework in which Canadian dentists practise; some re-emphasize established standards of care, such as the dental radiologist's mantra, ALARA (using a dose that is as low as reasonably achievable) and viewing images in reduced ambient lighting. Developments in the legislation that regulates the use of radiology, such as Health Canada"s Safety Code 30 for radiation safety in dentistry and the Healing Arts Radiation Protection Act, also affect the practice of dental radiology. Some technical developments, such as charge-coupled devices and photostimulatable phosphors, are already well-known to the profession. Teleradiology, currently used in hospitals, but unfamiliar to most dentists (especially those working in urban communities), may soon have an impact on dentistry when it is used for Canada"s electronic health record, now under development. In this first of 2 articles about dental digital technology, we discuss the legal impact of developments in oral and maxillofacial radiology on dental practice and patient care.

    Full Text Available Objectives: To evaluate the amount and nature of adult facial trauma in Aberdeen, Scotland’s third largest city, that requires referral to Aberdeen Royal Infirmary oral and maxillofacial surgery department by the Emergency Department and Grampian’s telemedicine service over a six month period.Material and Methods: A retrospective audit using oral and maxillofacial surgery trauma clinic and theatre records to identify Emergency Department (ED notes for those patients presenting with facial trauma. ED notes were examined to extract demographic data on each patient as well as information on the nature and outcomes of the facial trauma. This data was compared with previously published national and international statistics.Results: 137 patients were identified with a mean age of 33.7 years with a standard deviation of 16.7. 83.2% of facial trauma victims were male and 62% of facial injuries were caused by alleged assault. Only 1 patient was referred to Aberdeen Royal Infirmary by telemedicine. Conclusions: Aberdeen has a high number of injuries caused by interpersonal violence. Telemedicine is an underused resource in the referral and review of facial trauma at Aberdeen Royal Infirmary.

    Background and purpose: This retrospective study was to evaluate the local control and survival of {sup 125}I brachytherapy for recurrent and/or locally advanced adenoid cystic carcinoma (ACC) of the oral and maxillofacial region. Patients and methods: A total of 38 patients with recurrent and/or locally advanced ACC of the oral and maxillofacial region received {sup 125}I brachytherapy alone from 2001-2010. Twenty-nine were recurrent cases following previous surgery and radiation therapy. The other 9 cases involved primary tumors. Overall, 12 tumors were located in the major salivary glands, 12 in the minor salivary glands, and 14 in the paranasal region, the nasal cavity or the skull base. The prescribed dose was 100-160 Gy. Results: Patients were followed for 12-122 months (median 51 months). The 2-, 5-, and 10-year local tumor control rates were 86.3, 59, and 31.5 %, respectively. The 2-, 5-, and 10-year overall survival rates were 92.1, 65 and 34.1 %, respectively. Tumors > 6 cm had significantly lower local control and survival rates. No severe complications were observed during follow-up. Conclusion: {sup 125}I brachytherapy is a feasible and effective modality for the treatment of locally advanced unresectable or recurrent ACC.

    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.

    Strategies for management of patients with, or at risk for, medication-related osteonecrosis of the jaw (MRONJ) were set forth in the American Association of Oral and Maxillofacial Surgeons (AAOMS) position papers in 2007 and 2009. The position papers were developed by a special committee appointed by the board and composed of clinicians with extensive experience in caring for these patients and basic science researchers. The knowledge base and experience in addressing MRONJ has expanded, necessitating modifications and refinements to the previous position paper. This special committee met in September 2013 to appraise the current literature and revise the guidelines as indicated to reflect current knowledge in this field. This update contains revisions to diagnosis, staging, and management strategies and highlights current research status. The AAOMS considers it vitally important that this information be disseminated to other relevant health care professionals and organizations.

    This review summarises all orthognathic and related papers published between January 2011 and December 2012 in the British Journal of Oral and Maxillofacial Surgery (BJOMS). A total of 36 articles were published, a high proportion of which (78%) were full-length papers. The remainder consisted of short communications and technical notes. The topics included operative planning and postoperative outcomes, and there was a strong focus on distraction osteogenesis. There were fewer orthognathic articles published in BJOMS than articles on other subspecialties such as trauma or head and neck oncology. Only 8 (29%) of the full-length articles were prospective studies or randomised trials, which highlights a need for well-designed clinical studies in orthognathic research.

    2009-06-01

    This study reviewed the literature on cone-beam computerized tomography (CBCT) imaging of the oral and maxillofacial (OMF) region. A PUBMED search (National Library of Medicine, NCBI; revised 1 December 2007) from 1998 to December 2007 was conducted. This search revealed 375 papers, which were screened in detail. 176 papers were clinically relevant and were analyzed in detail. CBCT is used in OMF surgery and orthodontics for numerous clinical applications, particularly for its low cost, easy accessibility and low radiation compared with multi-slice computerized tomography. The results of this systematic review show that there is a lack of evidence-based data on the radiation dose for CBCT imaging. Terminology and technical device properties and settings were not consistent in the literature. An attempt was made to provide a minimal set of CBCT device-related parameters for dedicated OMF scanners as a guideline for future studies.

    The aim of this review was to assess the workload of theatres in the role 3 Multinational Field Hospital in Kandahar, Afghanistan and to identify what period of day most emergency admissions arrived. During the period 05 August 2006 to 21 December 2006, 288 operations were performed on 259 patients and comprised 393 individually quantifiable procedures. 98% of these operations were to treat acute injuries. Oral and Maxillofacial surgeons were involved in 24% of operations. 63% of procedures done at these operations involved upper or lower limbs, 19% the head and neck and 18% involved the torso. An analysis of emergency admissions in November 2006 showed that most occurred between 18.00 and midnight. Although theatre timetabling made provision for this, whenever possible, elective surgery was scheduled for the following morning when emergency injury admissions were at their lowest.

    A total of 2193 tumours of the mouth and jaw diagnosed at the Laboratorium Patologi Anatomi Fakultas Kedokteran Universitas Airlangga, Indonesia from 1987 to 1992, inclusive, was studied. Malignant tumours constituted 45.3% of the lesions. Almost 71% of the malignant tumours were squamous cell carcinomas. The remainder were salivary gland tumours (21.5%) and sarcomas (4.5%). The male to female ratio for malignant tumours was 5.1:4.7. The incidence of malignant tumours per 100,000 population over the 6-year study period was 2.64. The yearly incidence seemed to increase except in 1990, when it dropped. The incidence of squamous cell carcinoma over the 6 years was 2.1. Calculation of the odds ratio suggested that people aged 40 and over are 5.8 times more likely to develop squamous cell carcinoma.

    Guillaine-Barré Syndrome (GBS), also known as post-infectious polyneuropathy or acute idiopathic polyneuritis, is an infrequent disorder of the peripheral nervous system. The cause of GBS is unknown. It has been associated in the past with microbial infections, vaccinations, surgical procedures and debilitation of the patient. The classic signs of GBS occurring in the two patients being reported here are muscle weakness, motor and sensory impairment and ascending paralysis with respiratory involvement. The documented cases involved GBS syndrome following oral and maxillofacial surgery in which allogeneic-banked freeze-dried bone have been utilized along with autogenous grafting. There were no incidents of viral infection, vaccination or the other prodromal incidents involved in these cases. It is believed that the description of these two cases would be of interest in that it may stimulate the reporting of similar anecdotal occurrences by other surgeons. Both patients fully recovered from the GBS and are presently alive and well. PMID:26261679

    The treatment of maxillofacial injuries forms a substantial part of the work in oral and maxillofacial units, but injuries sustained in work-related incidents are uncommon, mainly because of the strict enforcement of Health and Safety policies. We used data from the Health and Safety Executive in the United Kingdom to review the incidence and aetiology of maxillofacial injuries that result from industrial accidents in the UK, and highlight the case of a worker who sustained an isolated fracture of the nasoethmoidal complex when he was trapped in a cheese press. In 2010-2011, roughly 115,379 accidents or incidents at work were reported in the UK, and of the 1623 (1%) that were maxillofacial, 81% occurred in the service sector. The most common mechanism of injury was assault (37%) and the most common injury was contusion (30%). Since the introduction of the Health and Safety Act, work-related accidents in the UK have decreased considerably. However, they will continue to occur because of human error.

    Full Text Available Introduction: As a result of aging process, oral mucosa becomes susceptible to oral diseases. Having knowledge about prevalence and distribution of geriatric oral diseases is essential for prevention and treatment planning. This study aimed to evaluate the prevalence of geriatric patients’ oral biopsies in specimens obtained in medical centers of Zahedan University of Medical Sciences. Methods: This cross-sectional study was conducted on 2496 cases of biopsied oral lesions found in pathology archive of medical centers of Zahedan University of Medical Sciences throughout a 20-year period.  Information about age, gender, lesion location and type of oral lesions of patients over 60 years old were collected and analyzed using SPSS software. Results: In this cross-sectional study, 412 (16.5% biopsy samples were taken from patients over 60 years old. Most subjects were in their seventh decade (59.5%, male (56.1% and soft tissue (96.6%. Two hundred and sixty (63.1% cases were neoplastic lesions and 152 (36.9% were non-neoplastic. There was no significant relationship between the type of lesions (neoplastic and non-neoplastic and age, gender and their location. The most prevalent lesions were oral squamous cell carcinoma (42.5%, non-specific inflammatory lesions (7.8%, irritation fibroma (3.4% and oral verrucous carcinoma (3.4%. Conclusion: Since the malignant lesions were the most common oral lesions in the studied geriatric patients, oral health care must be prioritized in the general health policies.

    Full Text Available Background: A progressive increase in the incidence and mortality of oral cancer is expected in Sudan. However, updated information on the epidemiology and pattern of the disease in the country is needed to draw the attention of the local authorities. Aim: The aim of this study has been to describe the pattern of cancer cases attending a referral oral and maxillofacial hospital in Sudan during the period 2006-2007. Settings and Design: The investigation was conducted as a cross-sectional study using the hospital records. Materials and Methods: From the hospital database, all cancer cases registered during the study period have been reported and their demographic characteristics, clinical information and history of oral habits were included. Statistics: Statistical Package for Social Sciences (version 12 was used for data analysis. Frequency distributions of the study variables were made and the association between pairs of variables was examined using the Chi-square test with a level of significance of 0.01. Results and Conclusion: Of the 261 cases included in this study, the most common pattern was found to be an intraoral squamous cell carcinoma (73.6%. The male to female ratio was approximately 3:2. Dropout rates were alarmingly high regardless of the patient′s state of residence. The observation of this study indicated that most of the patients seek treatment when the tumor reaches late stage. More public health efforts are therefore needed to investigate the current impact of the problem as well as for prevention and early detection of the cases.

    How many incorrect response options (known as distractors) to use in multiple-choice questions has been the source of considerable debate in the assessment literature, especially relative to influence on the likelihood of students' guessing the correct answer. This study compared distractor use by second-year dental students in three successive oral and maxillofacial pathology classes that had three different examination question formats and scoring resulting in different levels of academic performance. One class was given all multiple-choice questions; the two other were given half multiple-choice questions, with and without formula scoring, and half un-cued short-answer questions. Use by at least 1 percent of the students was found to better identify functioning distractors than higher cutoffs. The average number of functioning distractors differed among the three classes and did not always correspond to differences in class scores. Increased numbers of functioning distractors were associated with higher question discrimination and greater question difficulty. Fewer functioning distractors fostered more effective student guessing and overestimation of academic achievement. Appropriate identification of functioning distractors is essential for improving examination quality and better estimating actual student knowledge through retrospective use of formula scoring, where the amount subtracted for incorrect answers is based on the harmonic mean number of functioning distractors.

    As the new millennium approaches, it seems appropriate to look back at where we have been and where we are going with the care of patients with facial deformities. None of us can deny that although changes have been made, many current treatment modalities are no more than modifications of old techniques. We are, however, poised to make dramatic improvements in the management of facial abnormalities as we enter the new century and millennium. Biotechnology, genetic manipulation, and new surgical technology will become pervasive, and perhaps we will move from "modification" of the old into a completely new era of therapeutic approaches to the care of dentofacial deformities. "Opportunities multiply as they are seized" (from Sun Tzu), and the time of opportunity is approaching. This review will attempt to look at the state of the art in cleft care and in oral and maxillofacial surgery: where we have been and where we are going. It will be clear that there is overlap between specialties and that these overlaps will become greater as new regimens in the care of facial deformities come to the forefront.

    Two thousand-two hundred-forty-three cases of various lesions of the oral and maxillofacial region in children under 16 years of age were reviewed. The lesions were classified by 10 groups, osteomyelitis, cysts, benign tumors, malignant tumors, fibro-osseous lesions, developmental disturbances, antral lesions, TMJ lesions, salivary gland lesions, and other lesions. The obtained results were as follows; 1. Developmental disturbances, especially cleft alveolus and palate, was the most common lesions (25.7%), followed by cysts (22.5%), antral lesions (12.7%), benign tumors (11.9%) and osteomyelitis (9.3%). 2. With the time, the incidence of osteomyelitis and malignant tumors has been decreased, but that of developmental disturbances, cysts and antral lesions has been increased. 3. The sex distribution was relatively equal for the entire series, with male predominence in cysts, malignant tumors, developmental disturbances and salivary gland lesions and with female predominance in TMJ lesions. 4. Children with malignant tumors and osteomyelitis were somewhat younger and those with TMJ lesions were somewhat older. 5. Heading the list of each group except osteomyelitis was dentigerous cyst, odontoma, malignant lymphoma, fibrous dysplasia, cleft alveolus and palate, inflammatory change, degenerative change of condylar process, sialolithiasis and simple bone cyst respectively.

    This article describes the transition of an oral and maxillofacial radiology course from a traditional lecture format to an interactive case-based, team-based, interdisciplinary, and intraprofessional learning model in advanced dental education. Forty-four postdoctoral dental students were enrolled in the course over a twelve-week period in the fall semester 2012. The class consisted of U.S.- and foreign-trained dentists enrolled in advanced education programs in various dental disciplines. The course faculty preassigned interdisciplinary teams with four or five students in each. The class met once a week for an hour. Ten of the twelve sessions consisted of a team presentation, individual quiz, team quiz, and case discussion. Each member of a team completed peer evaluation of other team members during weeks six and twelve of the course. The final course grade was a composite of individual and team quiz grades, team presentation, and peer evaluation grades. The overall class average was 90.43. Ninety-five percent of the class (42/44) had total team grades equal to or greater than total individual quiz grades. The objective of creating a new case-based, team-based, interdisciplinary, intraprofessional learning model in advanced dental education was achieved, and the initial student perception of the new format was positive.

    The influence of funding on the main outcome of a random control trial (RCT) is important, as it could potentially lead to bias towards industry, and results that are too optimistic. We investigated the association between funding, the published outcome, and the risk of bias in trials in oral and maxillofacial surgery (OMFS) published from January 2000 to May 2013 listed in PubMed. The methods used were scored using the risk of bias items given in a Delphi List. Sources of funding were recorded and categorised five ways: not funded, funded by industry, not funded by industry, supported by industry, and source of funds not clear. A total of 390 RCT met the inclusion criteria, and there was a correlation between funding and favourable main outcomes, although this was not significant. There was no correlation between the risk of bias and favourable results of the main outcome of a trial, or between the risk of bias and the reported source of funding in post-hoc analysis. We were unable to show a significant correlation between funding and a higher likelihood of a favourable result for the primary outcome in RCT in OMFS. We also failed to show a significant correlation between the risk of bias of a trial and its main outcome. In contrast, the source of funding proved to affect the risk of bias of a trial significantly, although not in post-hoc analysis. Funded trials were better organised, and so had a lower risk of bias.

  6. Nanostructured Guidance for Peripheral Nerve Injuries: A Review with a Perspective in the Oral and Maxillofacial Area

    Full Text Available Injury to peripheral nerves can occur as a result of various surgical procedures, including oral and maxillofacial surgery. In the case of nerve transaction, the gold standard treatment is the end-to-end reconnection of the two nerve stumps. When it cannot be performed, the actual strategies consist of the positioning of a nerve graft between the two stumps. Guided nerve regeneration using nano-structured scaffolds is a promising strategy to promote axon regeneration. Biodegradable electrospun conduits composed of aligned nanofibers is a new class of devices used to improve neurite extension and axon outgrowth. Self assembled peptide nanofibrous scaffolds (SAPNSs demonstrated promising results in animal models for central nervous system injuries, and, more recently, for peripheral nerve injury. Aims of this work are (1 to review electrospun and self-assembled nanofibrous scaffolds use in vitro and in vivo for peripheral nerve regeneration; and (2 its application in peripheral nerve injuries treatment. The review focused on nanofibrous scaffolds with a diameter of less than approximately 250 nm. The conjugation in a nano scale of a natural bioactive factor with a resorbable synthetic or natural material may represent the best compromise providing both biological and mechanical cues for guided nerve regeneration. Injured peripheral nerves, such as trigeminal and facial, may benefit from these treatments.

    This paper provides a summary of the 95 papers related to oncology that were published in the British Journal of Oral and Maxillofacial Surgery (BJOMS) during 2007-2008. They include full length articles on clinical studies, radiology, basic science, and reconstruction in oral, and head and neck cancer. The journal also publishes technical notes and short communications. It encompasses the whole remit of the specialty and it is encouraging that authors choose to submit their work to BJOMS, but to improve the quality and status of the journal, we need to increase the ratio of full length articles to other submissions. Reviews of other subspecialties will be published in due course.

    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.

    The purpose of this study was to find out the rate of peer-reviewed publication of full papers of abstracts presented at the annual meeting of the Oral and Maxillofacial Surgery Society of Turkey, and to identify the time taken for publication, subspecialty, and study design. All abstracts accepted for presentation at the meetings in 2007-12 were identified from the books of abstracts, and evidence of publication was sought from PubMed and Google Scholar. The following variables were evaluated: publication rate, type of presentation (oral or poster), time to publication, subspecialty, study design, name of the journal in which the paper was published, impact factor of the journal, author affiliation, change in number of authors and origin of the study. A total of 1322 abstracts were presented between 2007 and 2012. Of these, 246 (19%) were subsequently published in peer-reviewed journals, including 110/390 oral presentations (28%) and 136/932 poster presentations (15%). Oral presentations were more likely to be published than poster presentations (p=0.000). The mean (SD) time from presentation to publication was 17 (15) months. Anatomical presentations had the highest publication rate (8/11), whereas orthognathic surgery had the lowest (5/67, 7%). Technical notes (5/9) and animal studies (32/70, 46%) were the most common types of publication. Only 246 of the 1322 abstracts (19%) were subsequently published as full papers, which is lower than previously reported in oral and maxillofacial surgery.

    Accurate and timely collection of clinical records is of utmost importance in planning, evaluating, and auditing orthognathic operations. The minimum dataset guidelines of the British Orthodontic Society (BOS) and the British Association of Oral and Maxillofacial Surgeons (BAOMS) were published in an attempt to standardise the collection of clinical records of patients having orthognathic operations. This multicentre retrospective audit aimed to assess and compare compliance with the guidelines in 3 maxillofacial units over a 1-year period. A total of 105 cases were reviewed. Compliance varied. Documentation of altered sensation was consistently poor and too many unnecessary radiographs were taken. There may be a need to circulate the guidelines again to increase awareness and reduce variability between centres.

    2013-08-01

    To summarize the potential benefits and risks of maxillofacial cone beam computed tomography (CBCT) use in orthodontic diagnosis, treatment and outcomes and to provide clinical guidance to dental practitioners. This statement was developed by consensus agreement of a panel convened by the American Academy of Oral and Maxillofacial Radiology (AAOMR). The literature on the clinical efficacy of and radiation dose concepts associated with CBCT in all aspects of orthodontic practice was reviewed. The panel concluded that the use of CBCT in orthodontic treatment should be justified on an individual basis, based on clinical presentation. This statement provides general recommendations, specific use selection recommendations, optimization protocols, and radiation-dose, risk-assessment strategies for CBCT imaging in orthodontic diagnosis, treatment and outcomes. The AAOMR supports the safe use of CBCT in dentistry. This position statement is periodically revised to reflect new evidence and, without reapproval, becomes invalid after 5 years. Copyright © 2013.

    Full Text Available SUMMARY: The Father of Maxillofacial Surgery is General Surgery and not Oral Surgery, as it may seem from a clinical point of view. General Surgery was the precursor of the specialty of Maxillofacial Surgery since the era of the Hippocratics and up to the end of the 18th century and the begining of the 19th century, having as pioneers eminent general surgeons, such as Heister, von Graefe, C. Langenbeck, Syme, Dupuytren,Roux, Chassaignak, Hulihen, Mott, Billroth, B. Langen -beck, Kocher, Macewen, Albert, Broca, and others.The range of action of the a forementioned surgeons included mostly (in 80% of the cases surgical procedures in the maxillofacial area, mainly in the fields of Traumatology (facial fractures, Osteoplasty, reconstructive surgery (cleft lip and cleft palate operations,and the treatment of tumors.In the present article the historical elements connected with the roots of Oncologic Surgery in the maxillofacial area are outlined, an activity developed by the general surgeons of these eras, which are at the same time the pioneers of modern Maxillofacial Surgery.

    Hutchinson-Guilford progeria is a rare genetic condition showing the stigmata of accelerated ageing combined with severe growth retardation. Patients with this condition show a classical facies and clinical features with an average age of death of 13, usually due to atherosclerotic changes. Craniofacial and dental manifestations include mandibular and maxillary hypoplasia, both vertically and horizontally. Delayed and abnormal tooth eruption and morphology are commonly present. The long-term medical prognosis and eruption potential of individual teeth is important when considering treatment. In addition to this, surgical planning and surgical technique must be modified by the abnormal facial morphology, dermal inelasticity, potential anaesthetic difficulties, and ongoing deterioration in the medical condition. These factors mandate early and definitive intervention for oral surgical conditions. We report the case of a 13-year-old male treated for pericoronitis and oral pain relating to delayed eruption of first permanent molars.

    Injuries and violence are one of the leading causes of mortality worldwide. A substantial portion of these injuries involve the maxillofacial region. Among the concomitant injuries, injuries to the head and cervical spine are amongst those that demand due consideration on account of their life threatening behaviour. Studies have shown that facial fractures have a strong association with traumatic brain injury. Knowledge of the types and mechanisms of traumatic brain injury is crucial for their treatment. Many a times, facial fractures tend to distract our attention from more severe and often life threatening injuries. Early diagnosis of these intracranial haemorrhage leads to prompt treatment which is essential to improve the outcome of these patients. An oral and maxillofacial surgeon should be able to suspect and diagnose head injury and also provide adequate initial management. PMID:26894193

    Full Text Available Craniorofacial trauma often manifests itself as a multisystem injury in 20-50% of the cases. Midface and zygomatic bone fractures are the most commonly occurring injuries together in developing countries due to inadequate road traffic legislations while mandible fractures are common due to its most predominant position in face and also due to interpersonal conflicts/assaults. Neurosurgeons and oral & maxillofacial surgeons play a very vital role along with neurologists and ophthalmologists in managing a craniorofacial trauma patient. The emergency physicians must be an expertise to manage the situation and stabilize a patient with severe traumatic injuries of craniorofacial region.

    The British Journal of Oral and Maxillofacial Surgery (BJOMS) publishes many types of papers including original articles, review articles, and short communications. Many of the latter are isolated case reports of rare or interesting diseases or of difficult or unexpected complications. While case reports are sometimes considered to be of little educational or clinical value, and as such do little to advance medical knowledge, they do have an important role, and many trainees begin their publishing careers writing such papers. There is increasing pressure for space in paper medical journals and, for this reason, some journals either limit or do not publish short publications in print copy but instead put them online. Using established criteria, we previously evaluated all 142 short communications published in the BJOMS during 2008-2009 and found that 48% of them had little or no educational value. As a result, the editorial board of BJOMS took the decision to publish most short communications online only. We have now analysed 48 short communications that were published online only during 2010-2011. Most (80%) were single case reports that covered virtually the whole remit of the specialty, and over half (56%) were published by authors based in the UK. While many of these papers did not add important new information to existing knowledge, these types of article are clearly of value both for trainees and for experienced surgeons. We think that these should continue to be supported as, in addition to their educational value, they are an excellent way for trainees to start to write.

    The aim of this study was to describe the implementation of one form of social media (Twitter) in an oral radiology course and evaluate dental students' use and perceptions of this technology for teaching and learning. An author-developed questionnaire was used to solicit second-year students' knowledge, use, and perceptions of Twitter for teaching and learning in an oral radiology course at one U.S. dental school. A combination of Likert scales, multiple allowable answers, and an open-ended comment question was employed. The questionnaire was piloted in spring 2010 followed by data collection in spring 2011. Out of 45 students, 40 (88.9%) completed the questionnaire. Of the respondents, 95% reported having not used Twitter prior to their second year of dental school; 55% of them created an account for the course. The top two reasons they gave for creating an account were viewing radiographic examples and staying informed about questions and answers that were posted. The top two reasons they gave for not creating an account were that the content was viewable online without an account and not wanting another online account. The students perceived the Twitter sessions as helpful and reported it improved accessibility to the instructor. The results of this study challenged the assumption that dental students are well versed in all forms of social media, but overall, these students agreed that the use of Twitter had enhanced the learning environment in the radiology course.

    The social, financial, and health implications of adult alcohol-related oral and maxillofacial trauma have been recognized for several years. Affordability and widespread accessibility of alcohol and issues of misuse in the pediatric trauma population have fostered concerns alcohol may be similarly implicated in young patients with orofacial trauma. The aim of this study was to review data of pediatric facial injuries at a regional maxillofacial unit, assess the prevalence of alcohol use, and review data of patients sustaining injury secondary to interpersonal violence. This study is a retrospective, 3-year review of a Regional Maxillofacial Unit (RMU) trauma database. Inclusion criterion was consecutive facial trauma patients under 16 years of age, referred to RMU for further assessment and/or management. Alcohol use and injuries sustained were reviewed. Of 1,192 pediatric facial trauma patients, 35 (2.9%) were associated with alcohol intake. A total of 145 (12.2%) alleged assault as the mechanism of injury, with older (12-15 years) (n = 129; 88.9%), male (n = 124; 85.5%) (p role of alcohol in the pediatric trauma population is essential.

    Full Text Available Despite the large number of published cases about oral and maxillofacial pediatric lesions, the literature is scarce on epidemiological studies regarding the prevalence of these entities. This study retrieved oral and maxillofacial pediatric lesions from the Center of Diagnosis of Oral Diseases (CDDB at the Dental School of the Federal University of Pelotas (UFPEL, comprising a 20-year period (1983-2002. From the total of 9,465 biopsies received in this period, 625 (6.6% were from children aged 0 to 14 years. Regardless of the histopathological diagnosis, patient data referring to lesion location, sex and age were collected. Diagnoses were grouped in 13 categories. As much as 89% of the cases occurred in patients aged 7 to 14 years (53% in females and 47% in males. Mucocele (17.2% was the most common type of lesion, followed by dentigerous cyst (8.6%. In the category of odontogenic tumors, odontoma was the most frequent lesion (64.2%. Malignant lesions were observed in a small section of the sample (1.2%. Generally, the results of the present study are in line with those reported in the literature concerning the most prevalent lesions in the pediatric population. Most lesions were benign, and malignant lesions were diagnosed in a very small part of the sample.

    Knowing what patients think about their care is fundamental to the provision of an effective, quality service, and it can help to direct change and reduce costs. Much of the work in oral and maxillofacial departments concerns the treatment of outpatients, but as little is known about what they think about their care, we aimed to find out which aspects were associated with satisfaction. Consecutive patients (n=244) who attended the oral and maxillofacial outpatient department at Southampton University Hospital NHS Foundation Trust over a 7-day period were given a questionnaire to complete before and after their consultation. It included questions with Likert scale responses on environmental, procedural, and interactive aspects of the visit, and a 16-point scale to rank their priorities. A total of 187 patients (77%) completed the questionnaires. No association was found between expected (p=0.93) or actual (p=0.41) waiting times, and 90% of patients were satisfied with their visit. Seeing the doctor, having confidence in the treatment plan, being listened to, and the ability of the doctor to recognise their personal needs, were ranked as important. Environmental and procedural aspects were considered the least important. These findings may be of value in the development of services to improve patient-centred care.

    Dental procedures are often performed on patients who present with some level of medical fragility. In many dental schools, the exercise of taking a medical history is all too often a transcription of information to the dental chart, with little emphasis on the presurgical risk assessment and the development of a treatment plan appropriate to the medical status of the dental patient. Changes in dentistry, driven by an increasingly medically complex population of dental patients, combined with treatment advances rooted in the biomedical sciences necessitate the adaptation of our dental education to include a stronger background in systemic health. Many predoctoral educators in the American Association of Oral and Maxillofacial Surgeons (AAOMS) have expressed concern about the medical preparedness of our dental students; therefore, the AAOMS and its Committee on Predoctoral Education and Training have provided recommendations for improving the medical curriculum in predoctoral dental education, including a strengthening of training in clinical medicine and biomedical sciences, with specific recommendations for improved training of our dental students and dental faculty.

    Facial trauma in children and adolescents is reported to range from 1% to 30%. Because of many anatomical, physiological, and psychological characteristics of the pediatric population, maxillofacial injuries in children should be treated with special consideration that is attributable to certain features inherent in facial growth patterns of children. This study evaluated maxillofacial injuries in 726 children in terms of incidence, patterns of injury, causes, and treatment modalities and compared these parameters among 3 pediatric age groups. Intergroup differences were analyzed using Z test for 2 populations' proportion. The results showed that the incidence of pediatric maxillofacial injuries and fractures is higher than that reported elsewhere with male predominance. Soft tissue injuries are more frequently encountered in younger individuals, whereas the incidence of skeletal injuries increases with age. This study also revealed that certain etiologies, namely road traffic accidents, violence, bicycle, missiles, and industrial injures, increase with age; on the other hand, falls and puncture wounds are more common in younger children.

    Full Text Available Abstract Background To improve the accuracy of catheter navigation, it is important to develop a method to predict shifts of carotid artery (CA bifurcations caused by intraoperative deformation. An important factor affecting the accuracy of electromagnetic maxillofacial catheter navigation systems is CA deformations. We aimed to assess CA deformation in different head and neck positions. Methods Using two sets of computed tomography angiography (CTA images of six patients, displacements of the skull (maxillofacial segments, C1–C4 cervical vertebrae, mandible (mandibular segment, and CA along with its branches were analyzed. Segmented rigid bones around CA were considered the main causes of CA deformation. After superimposition of maxillofacial segments, C1–C4 and mandible segments were superimposed separately for displacement measurements. Five bifurcation points (vA–vE were assessed after extracting the CA centerline. A new standardized coordinate system, regardless of patient-specific scanning positions, was employed. It was created using the principal axes of inertia of the maxillofacial bone segments of patients. Position and orientation parameters were transferred to this coordinate system. CA deformation in different head and neck positions was assessed. Results Absolute shifts in the center of gravity in the bone models for different segments were C1, 1.02 ± 0.9; C2, 2.18 ± 1.81; C3, 4.25 ± 3.85; C4, 5.90 ± 5.14; and mandible, 1.75 ± 2.76 mm. Shifts of CA bifurcations were vA, 5.52 ± 4.12; vB, 4.02 ± 3.27; vC, 4.39 ± 2.42; vD, 4.48 ± 1.88; and vE, 2.47 ± 1.32. Displacements, position changes, and orientation changes of C1–C4 segments as well as the displacements of all CA bifurcation points were similar in individual patients. Conclusions CA deformation was objectively proven as an important factor contributing to errors in maxillofacial navigation. Our study results suggest that

    Establishment and maintenance of fluent re-spiratory tract is important in management of general anesthe-sia in surgery for oral and maxillofacial injuries. Patients with oral and maxillofaeial injuries are likely to have obstruction of respiratory tract, especially patients with coma, massive hem-orrhage, foreign bodies in respiratory tract and wallowing tongue base. Studies showed that the mortality caused by re-spiratory problems is higher than that caused by injury itself in patients with oral and maxiUofacial injuries. Along with the in-novation of anesthesia, in-depth understanding of difficult re-spiratory tract and development of new anesthetic or instru-ment, more and more methods can be attained for management of the respiratory tract in surgery for oral and maxillofacial in-juries. The pivot of maintenance of fluent respiratory tract is taking effective steps to avoid lack of oxygen in pre-operation period. It is also important to use all kinds of intubation meth-ods and technologies skillfully.%维持气道通畅是口腔颌面创伤麻醉处理的重要课题.观察显示口腔颌面部外伤容易并发呼吸道梗阻,尤其是合并颅脑外伤者、昏迷状态、颌面部大出血、各种异物、舌根后坠等.相关报道合并颅脑外伤昏迷时,呼吸道问题引起的死亡,往往高于创伤本身.随着麻醉学技术的进步和对困难气道的深入认识以及麻醉药品器械的研制,解决问题的手段也日益增多.但每种解决办法都有自身特点,即适应证或禁忌证,尚需深入研究.颌面创伤气道的安全性关键在于围术期如何避免缺氧,有防范策略;其次是如何熟练应用各种插管方法.

    In dentistry and oral and maxillofacial surgery, the development of implantable biomaterials and the understanding of their molecular, cellular and pharmaceutical aspects are currently major fields of research and education, with a considerable impact on the daily clinical practice and the evolution of therapeutic strategies. In the era of globalized economy of knowledge and science, this scientific domain needs the development of global cooperation and a paradigm evolution in the organizational culture of the dental sciences and related dental industry. Despite political pressure and theoretical efforts, the internationalization of higher education and research today in dentistry and biomaterials remains in general quite superficial and mostly dependent on the efforts of a few leaders of internationalization working through their personal networks, as it was assessed through the FAST scores (Fast Assessment Screening Test) calculated in various dental schools and groups worldwide through the ISAIAS program (Intercultural Sensitivity Academic Index &Advanced Standards). Cooperation in a multipolar multicultural community requires the development of strong intercultural competences, and this process remains limited in most institutions. These limits of international scientific cooperation can be observed through different markers, particularly the difficult and limited production of ISO standards (International Organization for Standardization) and the relatively low SCIENTI scores (Scientific Cooperation Internationalization Effort &Network Test &Index) of the specialized dental literature, particularly in comparison to the most significant medical literature. However, as an analytical tool to assess the scientific international cooperation effort between fields and periods, the SCIENTI screening system also highlighted a significant increase of the internationalization effort in the last years in the best dental biomaterials publications. Finally, an

    2012-01-31

    The emergence of a new variant of subtrochanteric stress fractures of the femur, affecting patients on oral bisphosphonate therapy, has only recently been described. This fracture is often preceded by pain and distinctive radiographic changes (lateral cortical thickening), and associated with a characteristic fracture pattern (transverse fracture line and medial cortical spike). A retrospective review (2007-2009) was carried out for patients who were taking oral bisphosphonates and who sustained a subtrochanteric fracture after a low velocity injury. Eleven fractures were found in 10 patients matching the inclusion criteria outlined. All were females, and taking bisphosphonates for a mean of 43 years. Five of the 10 patients mentioned prodromal symptoms, for an average of 9.4 months before the fracture. Although all fractures were deemed low velocity, 5 of 11 were even atraumatic. Two patients had previously sustained contralateral subtrochanteric fractures. Plain radiographs of two patients showed lateral cortical thickening on the contralateral unfractured femur; the bisphosphonate therapy was stopped and close surveillance was started. Patients taking oral bisphosphonates may be at risk of a new variant of stress fracture of the proximal femur. Awareness of the symptoms is the key to ensure that appropriate investigations are undertaken.

    To compare the re-exposure rates of dental radiographs taken over a period of 1 year between dental students and trained dental assistants at a university-based oral and maxillofacial radiology clinic. Detailed records of the number and type of intraoral radiographs taken by the students and staff members and the number of re-exposures that were required from July 2003 to July 2004 were used. Statistical analyses were performed on the data. A chi2 test showed that re-exposure rates of radiographic series between students and staff were statistically different. When comparing the students' re-exposure rates during each of the four quarters of their radiology rotation, one-way analysis of variance test showed that the results were not statistically significant for reduction in the number of re-exposures over the entire year. There were significant differences in the re-exposure rates between staff dental assistants and students. Film re-exposure rates for the students during the four quarters were expected to decrease with time. Instead, the consistency of the re-exposure rates of the students during the four quarters demonstrates the need to recognize why the students did not perform better as the year progressed. The percentage of films that needed to be re-exposed by either group (students or the staff dental assistants) was not extremely high.

    Over the last 5 years, the medical profession has relied on the Bolam test for their defence in cases of clinical negligence. While still a matter of controversy between health professionals and legal experts, the Bolam test has been tried and criticised not only by the English courts but also in the United States, Canada, and Australia. In the medical profession the concept of the law of consent has moved away from a doctrine of professional paternalism towards patient-focused paternalism, and has increased the emphasis on human rights and the autonomy and choice of the patient. These changes present a challenge to health professionals, and a lack of effective recognition and interpretation can result in non-compliance. We review the developments in the law of consent since Bolam and discuss how they affect patients with incapacity, and highlight the importance of being familiar with them.

    By analyzing sports-related maxillofacial fractures, we sought to describe preventive measures and recovery times until sporting activities could be resumed. Between January 2001 and December 2006, 1241 patients were hospitalized as a result of maxillofacial fractures. The patients with sports-related maxillofacial fractures were analyzed based on age, sex, type of sport, injury mechanism, trauma site, presence of associated fractures, hospitalization, treatment method, and recovery time until the resumption of sporting activities. One hundred thirty-eight patients (11.4%) sustained sports-related maxillofacial fractures: 121 males and 17 females (ratio 8:1), aged between 11 and 72 years. The sport producing the greatest number of injuries was soccer (62.3%), followed by skiing (14.5%), and horseback riding (6.5%). The injuries involved mainly the middle third of the face (71.6%), and the mandible was the most affected site (27.2%), followed by the maxillary-zygomatic-orbital complex (25.9%). Treatment was surgery in 93.5% of the patients, with an average hospitalization period of 3.5 days. The protocol created to manage the follow-up of maxillofacial injury patients advised resuming sports activities at least 40 days after the trauma, except in the case of combat sports, when a period of 3 months was required. Although the results of this study indicate a reduction in the total incidence of sports-related maxillofacial injuries, they also show an alarming secondary increase in trauma resulting from the most popular sport in Italy-soccer. Therefore, stricter regulations are needed to discourage violent play, rather than relying on the use of protective equipment. Moreover, patients should be advised when they can resume sports activities, particularly in the case of professionals and semiprofessionals.

    Esthesioneuroblastoma is a rare malignant tumor of the sinonasal tract. Oral and maxillofacial pathologists rarely encounter this tumor in their daily practice. Because of their complex anatomic location, non-specific symptoms, varied histomorphology and unfamiliarity, most of the times, the tumor is diagnosed as benign tumor and thereby conservative treatment results in multiple recurrences. A recurrent case of esthesioneuroblastoma in a 24-year-old female patient describing the clinical, histopathological and immunohistochemical features along with differential diagnosis is discussed.

    Since its formation in June 2001, the Royal Centre for Defence Medicine (RCDM) at Birmingham University Hospitals NHS Foundation Trust has treated most of the British military personnel who have sustained serious maxillofacial injuries while serving abroad. We retrospectively analysed all recorded maxillofacial injuries of personnel evacuated to the RCDM between June 2001 and December 2007. We know of no existing papers that describe oral and maxillofacial injuries of military personnel, or workload in the 21st century. During the period 119 personnel with maxillofacial injuries were evacuated to the RCDM for treatment 83% of whom were injured in Iraq or Afghanistan. In total 61% (72/119) of injuries were caused by improvised explosive devices, 9% (11/119) were gun shot wounds, and 1% were caused by aircraft incidents. A further 29% (35/119) of patients had injuries not associated with battle. The most common injuries were facial lacerations (106/119). There were 54 facial fractures of which 17 primarily affected the maxilla, and 15 the mandible. Associated injuries were to the brain (24%), torso (26%), upper limb (39%), and lower limb (31%). The number of maxillofacial injuries has risen over the last 7 years, and has also increased in proportion to the total number of injured soldiers evacuated between 2005 and 2007.

    To determine how accurate and reliable oral maxillofacial radiologists (OMFRs) are in screening for adenoid hypertrophy when using cone-beam computed tomography (CBCT) imaging compared with nasopharyngoscopy (NP). CBCT scans of 10 patients with distinct levels of adenoid hypertrophy were randomly selected. Fourteen board-certified OMFRs classified the levels of hypertrophy. The intraclass correlation coefficient (ICC) was used to assess accuracy by comparing their diagnosis against an NP diagnosis, which is the reference standard. OMFRs' interreliability was assessed. Kappa statistics were used to analyze dichotomous data from healthy and unhealthy patients. Overall, the reliability among OMFRs was good (ICC = 0.79 with confidence interval [CI] 0.63-0.93). The "statistical mode" was very good (ICC = 0.81; CI 0.43-0.94). The accuracy of OMFRs against NP was good (ICCmean = 0.69; CI 0.43-0.94). On average, the Kappa statistics (Kmean = 0.77; CI 0.62-0.92) demonstrated a good agreement between OMFRs and NP diagnoses. The individualized results from each evaluator were presented and investigated according to their performance. Compared with the reference standard, the accuracy of OMFRs to classify adenoid hypertrophy on a four-level scale was moderate to strong and improved when adenoid hypertrophy was classified as healthy or unhealthy. The reliability of the OMFRs was greater than 80%, assuring their consistency and reliability on screening adenoids hypertrophy via CBCT. Copyright © 2016 Elsevier Inc. All rights reserved.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed analgesic agents in surgical outpatients. Major limitations of NSAIDs are their gastrointestinal (GI) adverse events (perforation, ulceration, and bleeding), impairment of hemostatic function, and renal failure (with long-term therapy). A new class of NSAIDs, the COX-2 selective inhibitors (CSIs or Coxibs), have been developed with the aim of reducing the GI adverse events of traditional NSAIDs while maintaining their effective anti-inflammatory and analgesic properties. This is a narrative review of the literature aimed to discuss analgesic efficacy, clinical safety and cost-benefit ratio of CSIs in the treatment of post-oral surgery pain. Relevant drug and clinical studies of analgesic efficacy and safety of CSIs in the management of postoperative dental pain were identified through searches of MEDLINE/PubMed, in peer-reviewed journals of medicine and dentistry. The Food and Drug Administration Web site was searched for data of tolerability. Hand-searching included several dental journals and bibliographies of relevant studies. The last electronic search was conducted in April 2003. Data from well-designed, randomized, controlled trials of CSIs on the management of post-oral surgery pain indicate that these drugs are as well-effective analgesic agents as traditional NSAIDs and offer clinical advantages in terms of GI safety and unimpaired platelet function. CSIs do not offer advantages of renal safety over traditional NSAIDs. Although CSIs display analgesic efficacy similar to that of traditional NSAIDs in the treatment of acute, post-oral surgery pain, there is reasonable evidence that these new drugs are preferable in patients who are at an increased risk of developing serious upper-GI complications, in patients who take aspirin for cardiovascular comorbid conditions, and in those allergic to aspirin. Furthermore, CSIs may be given more safely than NSAIDs in perioperative settings

    Full Text Available There has been considerable increase in maxillofacial and orbital injuries due to road traffic accidents, falls and assaults. There is need for accurate detection of these maxillofacial bony fractures. MDCT is the method of choice in the evaluation of maxillofacial traumas, as it allows accurate determination of the presence, location and extent of fractures especially in cases of communited fractures, rotational deformities and multiple bone fractures also having advantage to diagnose even in patients with facial edema, lacerations and altered sensorium. PURPOSE: The objective of the study is to compare axial, coronal and 3D reformatted CT images for the study of maxillofacial and orbital fractures. MATERIALS AND METHODS: Multislice CT scan was done for 131 patients attending BTGH Gulbarga with history of maxillofacial and orbital trauma during the period of December 2012 to September 2014 using Philips Brilliance 6 slice CT scanner. RESULTS : Majority of the patients were males (85.5% belonged to age group of 21 - 30 years (42%. Most common cause of maxillofacial trauma was road traffic accident (78.6%. Fractures of nasal bones were most common followed by walls of maxillary sinuses and least common fractured bone was cribriform plate. Most common type of complex fracture was naso - ethmoido - orbital complex fracture followed by zygomaticomaxillary complex. Lateral wall of the orbit was most commonly fractured followed by medial wall and floor. DISCUSSION : Axial CT was better in diagnosing anterior maxillary wall, zygomatic arch fractures. Coronal CT was better in detecting orbital floor, O rbital roof, P terygoid plate fractures, C lassification of Le Fort fractures and orbital floor blow out fractures. 3D CT was slightly better to 2D CT in evaluating anterior maxillary wall fractures and frontal bone fractures. 2D and 3D CT were almost similar in evaluating fractures of nasal bone, zygomatic bone and zygomatic arch fractures. 3D CT was

    Background: The aim of this study is to evaluate the various applications of cortical bone screws in oral and maxillofacial surgery. Materials & Methods: The study was conducted in a teaching hospital located in, Bangalore, India, on 20 patients. These patients were categorized into three groups depending on the applications of these screws like, for achieving intermaxillary fixation in Group-1, for treatment of simple, undisplaced fractures by “Tension wire” method in Group-2, and further application of these screws were evaluated in Group-3. Different parameters were used to evaluate the efficacy of these screws. Results: In Group-1(n=12) there was satisfactory occlusion in all the patients with minimal incidence of complications. In Group-2 (n=4) post-operative reduction and fixation was satisfactory and in Group-3 (n=4) the function of these screws was satisfactory when it was used for vestibuloplasty and also as a suspension wiring in treatment of comminuted fracture of zygoma with minimal incidence of complications. Conclusion: Use of cortical bone screws is a valid alternative for achieving intermaxillary fixation, reduction and fixation of simple, undisplaced or minimally displaced fractures through Tension wire method owing to its simplicity, economy and ease of use, and as a fixation method for apically positioned flap in vestibuloplasty procedure.

    We present an unusual dentoalveolar fracture case who had displacement of teeth into maxillary sinus cavity. This patient was 15 years old. He had oral bleeding and lost teeth after falling from the top of a building. Examination of maxillofacial region showed that there were left maxillary teeth lost, alveolar fracture, gingival bleeding and laserations. Maxillofacial bones were found intact. Canine, both premolars and the first molar teeth on left maxilla were lost. Pantomographic evaluation viewed two teeth in the left maxillary sinus. In addition, computerized tomography clearly showed oroantral fistula, alveolar fracture and teeth into maxillary sinus. Extraction of teeth from sinus cavity was performed as well as repair of oroantral fistula and alveolar fracture. This patient is thought that dentoalveolar injury may be more serious than expected according to the oral examination and it requires careful evaluation, even if dentoalveolar trauma does not pose a significant morbid risk.

    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

    Full Text Available Esthesioneuroblastoma is a rare malignant tumor of the sinonasal tract. Oral and maxillofacial pathologists rarely encounter this tumor in their daily practice. Because of their complex anatomic location, non-specific symptoms, varied histomorphology and unfamiliarity, most of the times, the tumor is diagnosed as benign tumor and thereby conservative treatment results in multiple recurrences. A recurrent case of esthesioneuroblastoma in a 24-year-old female patient describing the clinical, histopathological and immunohistochemical features along with differential diagnosis is discussed.

    Epilepsy is a relatively common neurological disorder with incidence in both developed and developing countries. Head, facial, and oral injuries can result from seizures experienced by the epileptic patient. Patients with severe epilepsy often experience other dental disease due to their inability to properly maintain their oral hygiene. This paper presents a case of a chronic mandibular fracture following an episode of seizures in a patient with epilepsy in whom the fracture was discovered when he developed a fistula in the submandibular region.

    Maxillofacial reconstruction by prosthetic means is a valuable contribution that medicine offers to the public. Materials design and properties are the main problems faced by scientists in this field. Materials used for intraoral prostheses are not ideal, but they have been perfected to the point of practical use. Denture resins, gold, chromium-cobalt alloys, and porcelain are widely used and produce acceptable results in the oral cavity. In this review, the properties and performance of some polymeric materials used in maxillofacial prosthetics are discussed, and new trends in research and development are also reported.

    Bisphosphonates are the primary therapy for postmenopausal and glucocorticoid-induced osteoporosis. Case series suggest a potential link between prolonged use of bisphosphonates and low-energy fracture of subtrochanteric or diaphyseal femur as a consequence of oversuppression of bone resorption. Using health care utilization data, we conducted a propensity score-matched cohort study to examine the incidence rates (IRs) and risk of subtrochanteric or diaphyseal femur fractures among oral bisphosphonate users compared with raloxifene or calcitonin users. A Cox proportional hazards model evaluated the risk of these fractures associated with duration of osteoporosis treatment. A total of 104 subtrochanteric or diaphyseal femur fractures were observed among 33,815 patients. The estimated IR of subtrochanteric or diaphyseal femur fractures per 1000 person-years was 1.46 [95% confidence interval (CI) 1.11-1.88] among the bisphosphonate users and 1.43 (95% CI 1.06-1.89) among raloxifene/calcitonin users. No significant association between bisphosphonate use and subtrochanteric or diaphyseal femur fractures was found [hazard ratio (HR) = 1.03, 95% CI 0.70-1.52] compared with raloxifene/calcitonin. Even with this large study size, we had little precision in estimating the risk of subtrochanteric or diaphyseal femur fractures in patients treated with bisphosphonates for longer than 5 years (HR = 2.02, 95% CI 0.41-10.00). The occurrence of subtrochanteric or diaphyseal femur fracture was rare. There was no evidence of an increased risk of subtrochanteric or diaphyseal femur fractures in bisphosphonate users compared with raloxifene/calcitonin users. However, this study cannot exclude the possibility that long-term bisphosphonate use may increase the risk of these fractures.

    Platelet concentrates for surgical use are innovative tools of regenerative medicine, and were widely tested in oral and maxillofacial surgery. Unfortunately, the literature on the topic is contradictory and the published data are difficult to sort and interpret. In bone graft, implant and reconstructive surgery, the literature is particularly dense about the use of the various forms of Platelet-Rich Plasma (PRP) - Pure Platelet-Rich Plasma (P-PRP) or Leukocyte- and Platelet-Rich Plasma (L-PRP) - but still limited about Platelet-Rich Fibrin (PRF) subfamilies. In this second article, we describe and discuss the current published knowledge about the use of PRP and PRF during implant placement (particularly as surface treatment for the stimulation of osseointegration), the treatment of peri-implant bone defects (after peri-implantitis, during implantation in an insufficient bone volume or during immediate post-extraction or post-avulsion implantation), the sinuslift procedures and various complex implant-supported treatments. Other potential applications of the platelet concentrates are also highlighted in maxillofacial reconstructive surgery, for the treatment of patients using bisphosphonates, anticoagulants or with post-tumoral irradiated maxilla. Finally, we particularly insist on the perspectives in this field, through the description and illustration of the use of L-PRF (Leukocyte- and Platelet-Rich Fibrin) clots and membranes during the regeneration of peri-implant bone defects, during the sinus-lift procedure and during complex implant-supported rehabilitations. The use of L-PRF allowed to define a new therapeutic concept called the Natural Bone Regeneration (NBR) for the reconstruction of the alveolar ridges at the gingival and bone levels. As it is illustrated in this article, the NBR principles allow to push away some technical limits of global implant-supported rehabilitations, particularly when combined with other powerful biotechnological tools

    A very popular sport worldwide, soccer generates a great number of maxillofacial injuries, mainly fractures, resulting in esthetic or functional problems. The aim of this retrospective study was to contribute to the knowledge of soccer-related maxillofacial injuries, and call attention to the risk factors that favor these injuries. A total of 108 patients, who attended hospital because of maxillofacial injuries during soccer within a period of 8 years, were included in this study. The relationship of the patients with soccer, the type, the site, the severity, the mechanism of the injuries and the applied treatment were analyzed. The injured were all males, and were principally amateurs. Around 89.8% of the patients suffered maxillofacial fractures while 10.2% presented only soft tissue injuries; 13.9% had multiple fractures; 50% of the maxillofacial fractures concerned the zygomatic complex and 38.2% the mandible where the majority occurred at the angle. The prevailing mechanism was the direct impact of players. Head to head impact outnumbered. Elbow to head impact caused contusions of the temporomandibular joint. Kick to head impact was the main cause of multiple fractures. The treatment of fractures was mainly surgical (68.2%). These findings support the fact that maxillofacial injuries sustained during soccer tend to be severe, demanding surgical treatment. The mandibular angle is in danger due to the usual existence of impacted and semi-impacted third molars. There should be a preventive intervention on the above contributors, and mainly coaches and sports physicians should be properly informed about the specificity of the maxillofacial injuries.

    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.

    Mandibular angle fractures continue to be a common type of facial injury. The objectives in treatment are to effect rapid healing by anatomic reduction and fixation and to restore function and appearance with minimal disability and complications. Traditionally, when open techniques are utilised, the extra-oral approach is performed through a skin incision concealed in the submandibular crease. However, patients develop unsightly scars and there is a risk of injury to the marginal mandibular nerve. In comparison, the trans-oral approach, performed through an oral mucosal incision, results in minimal external scarring or injury to the marginal mandibular nerve and allows direct visualisation and confirmation of the desired occlusion during the placement of the miniplates. The basic aim of the study was to provide a treatment for the mandibular fractures which results in minimal scarring and fulfills all the functional needs of the patient. Patients coming to KLES PK Hospital and MRC with mandibular angle fractures requiring open reduction and internal fixation admitted under OMFS were taken for the study. The sample size of the study was 15. In one group, the patients were treated by extra-oral approach and the other group by transbuccal approach. In patients treated by transbuccal approach, special armamentarium consisting of trocar, cannula, and cheek retractor were used; and in both the groups, semirigid fixation was done using two miniplates with around a distance of 1cm. Total of 15 patients were treated, 10 with transbuccal approach and 5 with submandibular approach. It has been found that both techniques fulfill the functional requirements of the patients. Patients treated with submandibular approach developed obvious unsightly scars, whereas transbuccal approach results in minimal scarring. The results associated with clinical observations suggest that transbuccal approach is a superior and less time consuming approach than extraoral approach, but it requires

    The purpose of the study was to evaluate the structure of maxillofacial trauma associated with brain injury in Stavropol to elaborate the diagnostic approach. We analyzed 2,604 case records of patients with maxillofacial trauma in the Stavropol region in the period from 2008 to 2012. Only 345 (13.2%) cases were diagnosed with maxillofacial trauma associated with mild brain injury. The analysis of case records showed that the incidence of brain damage depends on the location and type of fracture of the facial bones. It is noted that emotional and stress factors often mask neurological symptoms that are important in the diagnosis of traumatic brain injury. To ensure the treatment success and reduce the duration of disability patients with maxillofacial trauma must be provided with special treatment with a more thorough analysis of possible neurological deficit followed by mandatory therapy for neurological symptoms.

    The purpose of this study was to determine whether a relation exists between the presence of mandibular third molars (M3s) and mandibular angle and condylar fractures and whether the risk of these fractures varies with M3 position. A retrospective cohort study was conducted in patients with mandibular fractures presenting to the oral and maxillofacial surgery service from April 2007 to March 2012. Data sources were patients' hospital charts and panoramic radiographs. Predictor variables were the presence and position of M3s. M3 position was based on the Pell and Gregory classification and angulation was determined by measuring the angle between the long axis of the M3 and the mandibular occlusal plane. Outcome variables were the presence of angle and condylar fractures. Other study variables included age, gender, and fracture etiology. Data were analyzed using the χ(2) test and Student t test. The study sample consisted of 446 patients with 731 mandibular fractures. Results showed that the risk of mandibular angle fracture was significantly higher in patients and mandible sides with impacted M3s (P .05). The presence of impacted M3s increased the risk of angle fracture and simultaneously decreased the risk of condylar fracture. However, no relation appeared to exist between M3 position and fracture pattern. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

    2016-08-01

    Full Text Available Background & Objectives: Complex maxillofacial trauma is a common occurrence with high velocity road traffic accidents. Multiple facial bone fracture with loss of reference point for bony reduction requires use of intra-operative intermaxillary fixation to obtain good occlusion which precludes oral intubation. Fractures of nasal bones and ethmoid bones with complex distorted anatomy lead to inability to perform a nasal intubation. In such cases sub-mental intubation can be a safe and easy method of securing the intra-operative airway thus avoiding  tracheotomy and its complications.Materials & Methods: Retrospective clinical analytical study was planned in which 25 patients were included. Patient’s age, sex, type of trauma, time taken for procedure and complications were taken as study variables. Results: Average time taken for the procedure was nine minutes and only four out of 25 cases had complications. Conclusion: Sub-mental intubation requires simple skills, less time and is relatively complication free compared to tracheotomy in securing intra-operative airway during surgeries for complex maxillofacial trauma.JCMS Nepal. 2016;12(2:55-9

    The management of cranio-maxillofacial trauma includes treatment of facial bone fractures, dentoalveolar trauma, and soft tissue injuries. Integration of several specialties is often needed due to the proximity of the cranial bones to important organs such as the eyeballs, the nose, the ears, and the brain. The epidemiology of facial fractures varies in type, severity, and cause depending on the population studied. The differences between populations in the causes of maxillofacial fractures may be the result of risk factors and cultural differences between countries but are more likely to be influenced by the injury severity. Many epidemiologic investigations of maxillofacial fractures have appeared in the scientific literature over the years. Six main causes of injury were identified: motor vehicle accidents, occupational accidents, sport accidents, falls, assaults, and gun shot wounds. However, few reports, representing continuous long-term data on maxillofacial fractures in the state of Israel, are to be found. This study was undertaken to provide information regarding gender, age, etiology and diagnosis of patients with maxillofacial fractures, gleaned from our experience in the last 10 years (1996-2005), and to compare this information to the findings from the years 1985-1995, at the Department of Oral and Maxillofacial Surgery in the Chaim Sheba Medical Center, Tel Hashomer. The present study reviews retrospectively hospital records of 775 patients. Data regarding the 753 patients treated at the department in the years 1985-1995 was taken from previous publication. The diagnosis was based on radiographic data and clinical examination. The statistical analysis was carried out by the Statistics Department of Tel Aviv University. The majority of patients (74.2%) were males, the average age was 33.4 years, and the largest subgroup of patients (34%) was in the third decade of life. The most common cause of injury was falls (35%), followed by motor vehicle

    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.

    The purpose of this paper is to investigate the impact of a commercial lead apron on patient skin dose delivered during maxillofacial CBCT in five critical regions by means of solid-state-dosimetry. Five anatomical regions (thyroid gland, left and right breast, gonads, back of the phantom torso) in an adult female anthropomorphic phantom were selected for dose measurement by means of the highly sensitive solid-state dosimeter QUART didoSVM. Ten repeated single exposures were assessed for each patient body region for a total of five commercial CBCT devices with and without a lead apron present. Shielded and non-shielded exposures were compared under the paired Wilcoxon test, with absolute and relative differences computed. Reproducibility was expressed as the coefficient of variation (CV) between the 10 repeated assessments. The highest doses observed at skin level were found at the thyroid (mean shielded ± SD: 450.5 ± 346.7 μGy; non-shielded: 339.2 ± 348.8 μGy, p = 0.4922). Shielding resulted in a highly significant (p shielded dose of approximately 35 μGy. Dose reduction was also significantly lower for the back-region (mean: -65%, p shielded situation. Reproducibility was inversely correlated to skin dose (Rspearman = -0.748, p lead apron, which did not shield this region. Dose reduction by means of a commercial lead apron was significant in all other regions, particularly in the region of the female breast.

    It was recently demonstrated that ~80% of Merkel cell carcinomas (MCCs) harbour a novel polyomavirus, Merkel cell polyomavirus (MCPyV). MCPyV has been detected in various human tissue samples. However, previous studies on the prevalence of MCPyV in oral tumours or tumour-like lesions are incomplete. To address this issue, we measured MCPyV DNA quantity using quantitative polymerase chain reaction (qPCR) in 327 oral tumours or tumour-like lesions and 54 jaw tumours or cyst lesions from 381 immunocompetent patients, as well as in 4 oral lesions from 4 immunosuppressed patients. qPCR revealed a low MCPyV prevalence (25/381, 6.6%) with low viral loads (0.00024-0.026 copies/cell) in oral and maxillofacial tumours and tumour-like lesions from immunocompetent patients. The prevalence was 7/176 (4.0%) in invasive squamous cell carcinomas (SCCs) [2/60 (3.33%) SCCs of the tongue, 4/52 (7.7%) SCCs of the gingiva and 1/19 (5.3%) SCCs of the floor of the mouth], 1/10 (10%) in dysplasias, 1/5 (20%) in adenocarcinomas, 2/13 (15.4%) in adenoid cystic carcinomas, 1/10 (10%) in non-Hodgkin's lymphomas, 3/10 (30%) in lipomas, 3/5 (60%) in neurofibromas, 1/3 (33.3%) in Schwannomas, 2/12 (16.7%) in Warthin's tumours, 2/11 (18.2%) in pyogenic granulomas, 1/14 (7.1%) in radicular cysts and 1/12 (8.3%) in ameloblastomas. The prevalence in lesions from immunosuppressed patients (1/4, 25%) was higher compared with that in lesions from immunocompetent patients (25/381, 6.6%), but the difference was not statistically significant. To the best of our knowledge, this study was the first to report prevalence data of MCPyV in tumours and cysts of the jaws (2/54, 3.7%). These data indicated absence of MCPyV-related tumours or tumour-like lesions in the oral cavity and jaws and suggested that the detected MCPyV DNA was derived from non-neoplastic background tissues with widespread low-level MCPyV infection.

    2006-08-01

    Full Text Available Background and Aim: In recent years, CT scan has become available as an alternative to conventional radiography. To date, the utility of Waters view in detecting midface fractures has been rarely evaluated. The aim of this study was to compare the diagnostic accuracy and reliability of Waters radiography with CT scan in detecting midface fractures. Materials and Methods: In this tests evaluation study, waters view and CT scan were performed for 42 patients with midface fracture admitted to maxillofacial surgery department of Shariati hospital. All images were observed and interpreted by an oral and maxillofacial radiologist and an oral and maxillofacial surgeon. Sensitivity, specificity and reliability for Waters view in detecting midface fractures were assessed by Cohen’s kappa test. Results: Sensitivity and specificity for Waters view in detection of midface fratures by the radiologist were 31.79% and 95.35% and by the surgeon were 29.59% and 93.75% respectively. The highest reliability in CT scan and Waters view (in nasal fractures by the radiologist was 66.67% and was 58.33% by the surgeon in buttress of zygoma. The highest agreement rate between the radiologist and the surgeon for CT scan was in zygomatic arch (78.95% and for Waters view was in nasal fracture (62.5%. Conclusion: Based on the results of this study, the specificity of Waters view is sufficient to diagnose fractures of lateral orbital wall, infraorbital rim, orbital floor, zygomatic arch, frontozygomatic suture, lateral wall of maxillary sinus and Lefort II fracture. The specificity is not sufficient to diagnose fractures of medial orbital wall and anterior, posterior and medial wall of maxillary sinus. Detection of these midface fractures needs other conventional radiographies or CT scan.

    These clinical studies reflect the experience of the author in managing 673 patients treated during the last 8 years. All patients were treated in the Maxillofacial Unit, Surgical Specialties Hospital, Medical City, Baghdad, and in the author's private clinic. Included patients were 530 males and 143 females; patients' age ranged between 1 year and 75 years (mean, 38 y). Distribution of injuries was as follows: fracture of the mandible, 287 (42.64%); middle third injuries, 39 (5.79%); orbital injuries, 236 (35.07%; including 12 cases with cranioorbital injuries); injuries in children, 27 (4.0%); fracture of the zygoma, 52 (7.73%); and fracture of the nose, 40 (5.94%).Maxillofacial injuries in this study were classified as follows: (1) craniomaxillofacial with head injuries and cerebrospinal fluid leak; (2) fracture of the middle third including Le Fort I, II, and III and midline split in the face; (3) fracture of the mandible as an isolated injury or as part of a facial skeleton injury; and (4) isolated complex injuries of the zygoma, the orbital skeleton, and the nasoethmoidal region.The technique used for treating middle third injuries was external fixation either by halo frame (with vertical rods and cheek wires) or by box frame (using 4 external pins connected by rods) or internal fixation by suspending the middle third with internal wires (0.5 mm stainless steel) from the zygomatic process of the frontal bone beneath the zygomatic arch down the lower arch bar. Fractures of the mandible were treated by gunning splint with intermaxillary fixation (IMF) or with open reduction and fixation by stainless steel wire with IMF or by IMF screw or by an arch bar and IMF. Other fractures such as fracture of the orbit were treated by bone graft, sialastic, or lyophilized dura with open reduction. Fractures of the zygoma were treated by open reduction and fixation with stainless steel wire and bone graft or by reduction without fixation. Fractures of the nose were treated

    Full Text Available Objectives: This study aimed to identify the occurrence, type and severity of body injuries associated in patients with facial trauma, referred to the Hospital São Vicente de Paulo (HSVP in the city of Passo Fundo - RS, Brazil.Material and Methods: The study analyzed medical records of 1385 patients who were treated in the Department of Oral and Maxillofacial Surgery at HSVP during the period from 1991 to 2010.Results: According to the results of this study we observed that 35% of cases of facial fractures were associated with a body injury. It was recorded a higher incidence of facial fractures in the male population (82.6%, aged between 20 and 39 years. The main etiologic factors for this association were car accidents, falls and assaults. Most fractures were recorded in the mandible and the main body injury found was the abrasion associated in some region of the body, however, when considering fractures of the face middle third the main body injury was more associated with cranioencephalic trauma.Conclusions: Concomitant injuries in areas other than the face should be expected first and foremost after high-speed trauma mechanisms and in association with severe facial fractures. The results underscore the importance of multiprofessional collaboration in diagnosis and sequencing of treatment who have sustained facial fractures.

    OBJECTIVE To explore the new methods for oral care. METHODS According to the date of surgery, 86 patients receiving plastic and reconstructive surgery for maxillofacial reconstruction were divided into two groups. The oral flushing was used in the experimental group with 44 cases. The traditional oral care was used in the control group with 42 cases. The patients' subjective feeling of comfort, assessment by nurses, and bacterial cultures of oral secretions in two groups were compared after the surgery. The gender, age and pathogenetic condition of the 86 patients had no statistical significance. RESULTS After the treatment, the effect of oral care in the experimental group was better than that in the control group. The positive rate of the experimental group was 2. 3% , the control group was 28. 6%. The difference was statistically significant (P<0. 05).

    Cranio-maxillofacial trauma management requires pertinent documentation. Using a large computerized database, injury surveillance and research data describe the whole spectrum of injuries. The goal of this study was to assess the effect of the five main causes of accidents resulting in facial injury on the severity of cranio-maxillofacial trauma. During a period of 10 years (1991-2000) 9,543 patients were admitted to the Department of Oral and Maxillofacial Surgery, University Hospital of Innsbruck with cranio-maxillofacial trauma. Data of patients were prospectively recorded including cause of injury, age and gender, type of injury, injury mechanisms, location and frequency of soft tissue injuries, dentoalveolar trauma, facial bone fractures and concomitant injuries. Statistical analyses performed included descriptive analysis, chi square test, Fisher's exact test, and Mann-Whitney's U test. This was followed by logistic regression analyses for the three injury types to determine the impact of the five main causes on the type of injury at different ages in facial trauma patients. Five major categories/mechanisms of injury existed: in 3,613 (38%) cases it was activity of daily life, in 2991 (31%) sports, 1170 (12%) violence, in 1,116 (12%) traffic accidents, in 504 (5%) work accidents and in 149 (2%) other causes. A total of 3,578 patients (37.5%) had 7,061 facial bone fractures, 4,763 patients (49.9%) suffered from 6,237 dentoalveolar, and 5,968 patients (62.5%) from 7,769 soft tissue injuries. Gender distribution showed an overall male-to-female ratio of 2.1 to 1 and the mean age was 25.8+/-19.9 years; but both varied greatly depending on the injury mechanism (facial bone fractures: 35.4+/-19.5 years, higher risk for males; soft tissue injuries: 28.7+/-20.5, no gender preference; dentoalveolar trauma: 18+/-15.6, elevated risk for females). For patients sustaining facial trauma, logistic regression analyses revealed increased risks for facial bone fractures (225

    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.

    PURPOSE: To study the definitive surgical timing and indications in clinical comprehensive management of oral and maxillofacial trauma patients associated with multiple systemic injuries. METHODS: A total of 4869 patients with oral and maxillofacial trauma treated over a 20-year period in four general hospitals were retrospectively reviewed. The clinical conditions of associated multiple systemic injuries with oral and maxillofacial trauma and the specific definitive surgical timing were analyzed. RESULTS: 3364 patients had facial fractures, 1505 patients had soft tissue injuries. 1524 (31.3%) patients had injuries in other parts of the body, among which 570 (37.4%) were cranio-cerebral injuries, 545(35.8%) were orthopedic injuries, 170(11.2%) were thoracic injuries, 151(9.9%) were ophthalmic injuries, 54 (3.3%) were spinal injuries and 34 (2.2%) were abdominal injuries. There were 422 (74%) patients associated cranio-cerebral injuries in whom maxillofacial fractures surgery within 4 weeks after trauma, 115(76.2%) patients had associated ophthalmic injuries in whom maxillofacial fractures surgery was performed within the first 7 days after trauma. The maxillofacial definitive surgical treatment in some other associated patients including orthopedic, thoracic, abdominal and spinal injuries was delayed in different times. CONCLUSION: Clinical comprehensive management in maxillofacial trauma patients associated with multiple systemic injuries needs cooperation within multiple specialties and departments. A large number of oral and maxillofacial trauma patients with multiple systemic injuries are amenable to definitive maxillofacial surgery in early lime after trauma, or surgical management of other injuries of the body, if the conditions of respiratory and circulatory system were stable.%目的:研究伴发身体其他部位创伤的颌面伤患者综合救治中专科确定性手术时机和适应证.方法:回顾性统计4所大型综合医院口腔科病房近20

    Platelet concentrates for surgical use are innovative tools of regenerative medicine, and were widely tested in oral and maxillofacial surgery. Unfortunately, the literature on the topic is contradictory and the published data are difficult to sort and interpret. In periodontology and dentoalveolar surgery, the literature is particularly dense about the use of the various forms of Platelet-Rich Plasma (PRP) - Pure Platelet-Rich Plasma (P-PRP) or Leukocyte- and Platelet-Rich Plasma (L-PRP) - but still limited about Platelet-Rich Fibrin (PRF) subfamilies. In this first article, we describe and discuss the current published knowledge about the use of PRP and PRF during tooth avulsion or extraction, mucogingival surgery, Guided Tissue Regeneration (GTR) or bone filling of periodontal intrabony defects, and regeneration of alveolar ridges using Guided Bone Regeneration (GBR), in a comprehensive way and in order to avoid the traps of a confusing literature and to highlight the underlying universal mechanisms of these products. Finally, we particularly insist on the perspectives in this field, through the description and illustration of the systematic use of L-PRF (Leukocyte- and Platelet- Rich Fibrin) clots and membranes during tooth avulsion, cyst exeresis or the treatment of gingival recessions by root coverage. The use of L-PRF also allowed to define new therapeutic principles: NTR (Natural Tissue Regeneration) for the treatment of periodontal intrabony lesions and Natural Bone Regeneration (NBR) for the reconstruction of the alveolar ridges. In periodontology, this field of research will soon find his golden age by the development of user-friendly platelet concentrate procedures, and the definition of new efficient concepts and clinical protocols.

    Background The aim of this study was to analyzed the characteristics and treatment of maxillofacial injuries in the elder patients with maxillofacial injuries in central China. Material and Methods We retrospectively analyzed the characteristics and treatment of maxillofacial injuries in the patients over the age of 60 to analyze the trends and clinical characteristics of maxillofacial trauma in elder patients from the First Affiliated Hospital of Zhengzhou University (from 2010 to 2013) in central China and to present recommendations on prevention and management. Results Of the 932 patients with maxillofacial injuries, 126 aged over 60 years old accounting for 13.52% of all the patients (male:female, 1.74:1; mean age, 67.08 years old). Approximately 52% of the patients were injured by falls. The most frequently observed type of injuries was soft tissue injuries (100%), followed by facial fractures (83.05%). Of the patients with soft tissue injuries, the abrasions accounted the most, followed by lacerations. The numbers of patients of midface fracture (60 patients) were almost similar to the number of lower face fractures (66 patients). Eighty two patients (65.08%%) demonstrated associated injuries, of which craniocerebral injuries were the most prevalent. One hundred and four patients (82.54%) had other systemic medical conditions, with cardiovascular diseases the most and followed by metabolic diseases and musculoskeletal conditions. Furthermore, the study indicated a relationship between maxillofacial fractures and musculoskeletal conditions. Only 13 patients (10.32%) sustained local infections, of whom had other medical conditions. Most of the facial injuries (85.71%) in older people were operated including debridement, fixing loose teeth, reduction, intermaxillary fixation and open reduction and internal fixation (ORIF). Conclusions Our analysis of the characteristics of maxillofacial injuries in the elder patents may help to promote clinical research to

Meanwhile, nutritional support was given after screening and the effect was evaluated. METHODS: Fifty-nine patients with oral and maxillofacial cancers were enrolled in this study. The medical history and the intake condition of all patients were recorded, body weight and height were measured.The serum hemoglobin(Hb), lymphocyte count(LC), albumin(Alb), pre-albumin(PA) of the patients were detected. According to the requirements of NRS2002, the patients were screened before and after surgery. The patients with nutritional risks were divided into experimental group and control group randomly. The blood biochemical parameters in the two groups were compared after nutritional intervention. The data was analyzed by student's t test and Chi-square test with SPSS11.5 software package. RESULTS: Nutritional risk pre-operatively was 27.1% while the figure increased to 71.2% after operation (P<0.05). Compared to pre-operation, nutritional risk increased significantly. Hb, LC,Alb and PA decreased significantly (P<0.01). Before nutritional intervention,there was no difference of the biochemical stats between the patients in the experimental group and the control group (P>0.05). After 7 days' treatment, the biochemical parameters except Hb and PA increased significantly in the control group. In the experimental group, LC, Alb and PA increased significantly (P< 0.05), .especially Alb (P<0.01), but Hb decreased. Compared with the control group, the NRS 2002 score decreased significantly in the experimental group after nutritional intervention. CONCLUSIONS: NRS2002 can reflect the nutritional risk of the patients with oral and maxillofacial cancers conveniently and swiftly. Nutritional support after operation can significantly increase the nutritional status of the patients, reduce the infectious complications and

    3D image registration aims at aligning two 3D data sets in a common coordinate system, which has been widely used in computer vision, pattern recognition and computer assisted surgery. One challenging problem in 3D registration is that point-wise correspondences between two point sets are often unknown apriori. In this work, we develop an automatic algorithm for 3D maxillofacial models registration including facial surface model and skull model. Our proposed registration algorithm can achieve a good alignment result between partial and whole maxillofacial model in spite of ambiguous matching, which has a potential application in the oral and maxillofacial reparative and reconstructive surgery. The proposed algorithm includes three steps: (1) 3D-SIFT features extraction and FPFH descriptors construction; (2) feature matching using SAC-IA; (3) coarse rigid alignment and refinement by ICP. Experiments on facial surfaces and mandible skull models demonstrate the efficiency and robustness of our algorithm.

    There is an upward trend in facial injuries following changes in population pattern, increasing industrialization and urbanization, hence maxillofacial trauma is becoming a burden and a leading medical problem in emergency rooms worldwide. This study was performed to evaluate the pattern of maxillofacial fractures, associated injuries, and treatment used at Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences (AIIMS), New Delhi, India, between January 2007 and June 2010. The study provides basis for establishment of trauma as major etiology of maxillofacial injuries and planning for preventive strategies. A retrospective study of patients seen and treated at JPNATC, AIIMS, New Delhi, between January 2007 and June 2010 was performed. Data extracted from patient records included etiology, age, sex, types and sites of fractures, treatment modality, and concomitant injuries. There were 795 fractures of the maxillofacial skeleton and 86 concomitant injuries from 542 patients. Road traffic accident (RTA) (56.8%) was the most common etiologic factor, followed by falls (22.3%) and fights (18.5%). The age range was from 3 to 75 years (mean, 34.7 years) with a peak incidence in the third decade with a male-to-female ratio of 3.7:1. The most common location of maxillofacial fractures was the mandible 615 (77%) and middle third 180 (23%). With regard to mandibular fractures, the body (29.6%) was the most common site, followed by the angle (24.4%), ramus (19.5%), dentoalveolar (14.6%), symphysis (11.0%), condyle (0.8%) while in the middle third, the nasal bone (36.7%) was the most common, followed by zygomatic bone (27.8), Lefort II (14.4), Lefort I (7.8%), dentoalveolar (10.0%), and Lefort III (3.3%). Majority of the patients were treated by open reduction and internal fixation (70.6). Concomitant injuries were 84 (10.8%) with orthopedic injuries accounting for the majority (63.9%).

    Full Text Available   "nThe 3D cone beam volume/computed tomography (CBVT/CBCT has been designed for imaging the hard tissues of the maxillofacial region, although it has been used in some era of medical imaging for many years. CBVT is capable of providing a sub-millimeter resolution with the short scanning time of mostly less than 20 seconds and radiation dosages reportedly up to 15 times lower than those of spiral CT scans. In less than a decade, CBVT has revolutionized oral and maxillofacial radiology and is known as the “Standard of Care”. Although development was initially directed towards multiplanar viewing for dental implant and orthodontic treatment planning, secondary applications in other areas continue to expand such as maxillo-facial trauma, temporomandibular joint disorders, sinuse pathosis and upper airway evaluation. The intent of this presentation is to provide an overview of CBVT technology, advantages and disadvantages compared to the other modalities such as 2D images and medical CT and examples of justified cases in the oral & maxillofacial region.

    Seizure-related injuries are common and are a major cause of morbidity in subjects with epilepsy. To determine the frequency and types of oro-facial injuries in epileptic patients attending a tertiary hospital. A structured questionnaire was used to obtain information about injuries to the oral and maxillofacial region in epileptic patients at the Neurology Clinic of the Lagos University Teaching Hospital over a period of two years. Information sought included patient's sociodemographics, type of seizure, self-management of seizures, and history of injuries during seizures. Of the 138 epileptic patients seen, 87 (63.0%) reported the occurrence of oral and maxillofacial injuries. Mean age of these patients (29.6±12.1 years) was not significantly different from that of those who had no injuries (33.5±15.6 years). Prevalence of seizure-related injuries was not significantly different in males and females (50 [58.8%] vs 37 [71.2%]). Injuries were more likely in those who had convulsive seizures than in those who had non-convulsive seizures. Patients who had hard objects forced between their clenched teeth during seizure episodes were more likely to sustain injuries. Soft tissue injuries were more common than injuries to the facial bones and teeth. Of these, the tongue was the most commonly injured. Majority of those with soft tissue injuries did not receive treatment in hospital. Although fractures of the cheek and jaw bones were not so common, all such cases received surgical treatment in hospital. A high proportion of epileptic patients in Lagos appear to suffer seizure-related oro-facial injuries. Measures for the prevention and management of these injuries are needed to help reduce the morbidity caused by such injuries.

    Oral bisphosphonates (BPs) are highly effective in preventing fractures and are recommended first-line therapies for patients with osteoporosis. We identified the incidence and predictors of oral BP treatment failure, defined as the incidence of two or more fractures while on treatment (≥2 FWOT) among users with high adherence. Fractures were considered from 6 months after treatment initiation and up to 6 months after discontinuation. Data from computerized records and pharmacy invoices were obtained from Sistema d'Informació per al Desenvolupament de l'Investigació en Atenció Primària (SIDIAP; Catalonia, Spain) and Danish Health Registries (Denmark) for all incident users of oral BPs in 2006-2007 and 2000-2001, respectively. Fine and Gray survival models using backward-stepwise selection (p-entry 0.049; p- exit 0.10) and accounting for the competing risk of therapy cessation were used to identify predictors of ≥2 FWOT among patients having persisted with treatment ≥6 months with overall medication possession ratio (MPR) ≥80%. Incidence of ≥2 FWOT was 2.4 (95% confidence interval [CI], 1.8 to 3.2) and 1.7 (95% CI, 1.2 to 2.2) per 1000 patient-years (PYs) within Catalonia and Denmark, respectively. Older age was predictive of ≥2 FWOT in both Catalonian and Danish cohorts: subhazard ratio (SHR) = 2.28 (95% CI, 1.11 to 4.68) and SHR = 2.61 (95% CI, 0.98 to 6.95), respectively, for 65 to history of recent or older fracture, SHR = 3.40 (95% CI, 1.50 to 7.68) and SHR = 2.08 (95% CI: 1.04-4.15), respectively (Denmark). Even among highly adherent users of oral BP therapy, a minority sustain multiple fractures while on treatment. Older age was predictive of increased risk within both study populations, as was history of recent/old fracture and dementia within one but not both populations. Additional and/or alternative strategies should be investigated for these patients. © 2015 American Society for Bone and Mineral Research.

    Full Text Available Background: Trauma remains a leading cause of maxillofacial injury globally. Changing etiological factors and patterns of maxillofacial injury continue to be reported and are largely modulated by socio-geographic and environmental factors. It is important to have an in-depth understanding of the pattern and etiology in a particular region before effective preventive measures can be developed. Aim: The aim was to evaluate the patterns, etiological factors, and management of maxillofacial injuries in Ogun state, Nigeria. Materials and Methods: A prospective descriptive cohort study of all consecutive patients that presented with maxillofacial injuries at our center between January and December 2013. Information about demographic data, types of maxillofacial and associated injury, etiology of injury, treatment received and complications were collected and analyzed. Results: Seventy patients presented with maxillofacial injury during the study period with a male to female ratio of 4:1. The age range was 9 months to 60 years with a mean of 30.11 ΁ standard deviation 14.97 years. Majority of the facial fractures were due to motorcycle related crashes. There were 57.1% mandibular fractures and 55.7% middle third fractures. Closed reduction with maxillo-mandibular fixation was the major method of treatment of facial fractures. Postoperative complications were observed in 11.4% of patients. Conclusion: Road traffic crashes (RTCs remain the leading etiological factor of maxillofacial injuries in our center. Enforcement of stricter traffic regulations and possibly replacement of motorcycles with tricycles for commercial transportation may help to reduce the incidence of RTCs.

    Full Text Available The treatment of condylar process fractures has generated a great deal of discussion and controversy in oral and maxillofacial trauma and there are many different methods to treat this injury. For each type of condylar fracture, the techniques must be chosen taking into consideration the presence of teeth, fracture height, patient's adaptation, patient's masticatory system, disturbance of occlusal function, deviation of the mandible, internal derangements of the temporomandibular Joint (TMJ and ankylosis of the joint with resultant inability to move the jaw, all of which are sequelae of this injury. Many surgeons seem to favor closed treatment with maxillomandibular fixation (MMF, but in recent years, open treatment of condylar fractures with rigid internal fixation (RIF has become more common. The objective of this review was to evaluate the main variables that determine the choice of method for treatment of condylar fractures: open or closed, pointing out their indications, contra-indications, advantages and disadvantages.

    In Hungary, the number and structure of the maxillofacial surgery departments underwent significant changes in recent decades. The aim of our study was to present the actual performance indicators of maxillofacial inpatient departments and based on the available data to compare the departments. The study was based on the number of beds founded by the National Health Insurance Fund. Performance data were supplied by the National Health Insurance Fund Administration. The assessment included the following indicators: number of beds institutional breakdown by type, number of reimbursed cases, the weighted case number, hospital stay, bed occupancy rates and average length of stay. In the examined period 40% of active beds (65) were in university hospitals. The distribution of reimbursed cases was similar.

    Condyle fractures are common in children and are increasingly treated with open reduction. Three-dimensional printing has developed into an important method of assisting surgical treatment. This report describes the case of a 14-year-old patient treated for a right condyle fracture at the authors' hospital. Preoperatively, the authors designed a surgical guide using 3-dimensional printing and virtual surgery. The 3-dimensional surgical guide allowed accurate alignment of the fracture using Kirschner wire without additional dissection and tissue injury. Kirschner wire fixation augmented by 3-dimensional printing technology produced a good outcome in this adolescent condyle fracture.

    Full Text Available Distraction osteogenesis (DO, firstly introduced to the medical world by Russian scientist Ilizarov"nfor long bone lenghtening in orthopedics can be considered as an appropriate substitute in the treatment of"nmaxillofacial deformities. Natural events occuring during the repair of a fractured bone segment not only lead"nto the desired bone length but also prevent from the undesired disadvantages of osteotomies and bone"ngrafting. Recently a lot of investigations have been conducted to evaluate the efficacy of DO in the treatment"nof maxillofacial deformities, which in some cases have lead to successful results. In the present article a lot of"nissues in maxillofacial surgery and different treatment goals associated with DO are discussed.

  16. Management of tripod fractures (zygomaticomaxillary complex 1 point and 2 point fixations: A 5-year review

    2015-01-01

    Full Text Available The zygomaticomaxillary complex (ZMC plays a key role in the structure, function, and esthetic appearance of the facial skeleton. They can account for approximately 40% of mid-face fractures. They are the second most common facial bone fracture after nasal bone injuries. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma. In addition, the fracture components may result in impingement of the temporalis muscle, trismus (difficulty with mastication and may compromise the infraorbital foramen/nerve resulting in hypesthesia within its sensory distribution. A 4-year retrospective review of all patients treated with ZMC fractures at oral and maxillofacial surgery department, sree balaji dental college and hospital was performed. Computed tomography scans were reviewed. Demographics, treatment protocols, outcomes, complications, reoperations, and length of follow-up were identified. A total of 245 patients was identified by the Current Procedural Terminology codes for ZMC fractures. Closed or open reduction methods were performed with the goal of treatment being preservation of normal facial structure, sensory function, globe position, and mastication functionality. Unacceptably poor surgical outcomes are uncommon. Significant facial asymmetry requiring surgical revision occurs in 3-4% of patients. Postoperative infection rates are extremely low, and these infections nearly always resolve with oral antibiotics. In general, the long-term prognosis after repair of ZMC fractures is very good.

    Full Text Available Statement of Problem: Information about etiology and incidence of maxillofacial trauma is important for prevention and appropriate treatments of such injuries. Purpose: The purpose of this retrospective study was to conduct an analysis of maxillofacial injuries transferred and/or referred to the department of maxillofacial Surgery at Chamran emergency hospital, Shiraz, over a 6-year-period with special reference to age, gender, occupation, date, type, site, etiology and clinical management. Materials and Method: The data for this study were collected and reviewed retrospec-tively from the records and radiographs of 768 patients who were treated for maxillofacial trauma in the department of maxillofacial surgery at the Shiraz Chamran Emergency Hospital, Iran, between 2004 and 2010. Results: A total of 730 of the subjects were the patients with fractures of the facial skeleton. The mean age was 26.6± 12.6 years, ranging from 2 to 81 years. Traffic accident was the most frequent etiological factor of maxillofacial fractures irrespective of gender (69.9% for men and 54.2% for women, whereas the second most frequent cause of injuries was falling down (9.8% for men and 21.5% for women .The other etiologies were assault (5.2%, sport related injuries (1.3% and firearm injuries (1%. Regarding the head injuries in patients with maxillofacial fractures, brain contusion was seen in 227(29.6% patients and 13.5% of patients had lacerations in the facial soft tissue. The monthly distribution peaked in October, with 81 cases (10.5%, which seems to have been due to schools opening. The next highest incidence was in December, with 80 cases (10.4%, probably because of the changing weather's effect on road traffic. Conclusion: Isolated mandibular fracture due to the road traffic accident was the most common type of maxillofacial injuries in the city of Shiraz.

    2007-08-01

    Biomaterials science and technology have been expanding tremendously the recent years. The results of this evolution are obvious in maxillofacial applications especially with the contemporary development of Nanotechnology. Among biomaterials, bioceramics possess a specific field due to various interactions with the biological tissues. The combination of bioceramics and nanotechnology has resulted in enhanced skeletal interactions in maxillofacial applications. Nanotechnology secures better mechanical properties and more effective biological interactions with jaws. The main production methods for the synthesis of nanostructured materials include plasma arcing, chemical vapour deposition, sol-gel and precipitation. The bioceramics in Dentistry comprise inert, bioactive, resorbable and composite systems. The purpose of the present article is to describe the available nanotechnology methods and how these could be addressed to synthesise maxillofacial bioceramics with advanced properties for better biological applications. Additionally, it describes specific clinical applications in maxillofacial surgery of these biomaterials--either by themselves or in combination with others--that can be promising candidates for bone tissue engineering. Such applications include replacement of lost teeth, filling of jaws defects or reconstruction of mandible and temporomandibular joint.

    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.

    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.

    Hip fracture patients represent a large part of the elderly surgical population and face severe postoperative morbidity and excessive mortality compared to adult surgical hip fracture patients. Low antioxidant status and taurine deficiency is common in the elderly, and may negatively affect postoperative outcome. We hypothesized that taurine, an antioxidant, could improve clinical outcome in the elderly hip fracture patient. A double blind randomized, placebo controlled, clinical trial was conducted on elderly hip fracture patients. Supplementation started after admission and before surgery up to the sixth postoperative day. Markers of oxidative status were measured during hospitalization, and postoperative outcome was monitored for one year after surgery. Taurine supplementation did not improve in-hospital morbidity, medical comorbidities during the first year, or mortality during the first year. Taurine supplementation lowered postoperative oxidative stress, as shown by lower urinary 8-hydroxy-2-deoxyguanosine levels (Generalized estimating equations (GEE) analysis average difference over time; regression coefficient (Beta): -0.54; 95% CI: -1.08--0.01; p = 0.04), blunted plasma malondialdehyde response (Beta: 1.58; 95% CI: 0.00-3.15; p = 0.05) and a trend towards lower lactate to pyruvate ratio (Beta: -1.10; 95% CI: -2.33-0.12; p = 0.08). We concluded that peri-operative taurine supplementation attenuated postoperative oxidative stress in elderly hip fracture patients, but did not improve postoperative morbidity and mortality.

    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.

    Full Text Available The purpose of this study was to evaluate the incidence of trauma victims of age 60 years and older who required maxillofacial intervention. The study analyses the pattern of injuries and the various factors that predict the treatment plan of these patients. A retrospective study was carried out in 1820 trauma patients who reported to the Sri. Ramachandra Dental College and Hospital and required maxillofacial intervention, over a period of 5 years (October 2000 and September 2005. Of the total trauma victims, 185 patients were found to be aged 60 years more. In the majority of the patients, the injury was due to road traffic accidents (79.4%. Males (72.4% sustained more injuries than females (27.6%. Soft tissue injuries were seen in 49.1% of the patients, while 14% had mandibular fractures. People in their early 60s were injured more often than their older counterparts. The findings of this study highlight the present situation with regard to maxillofacial trauma in patients aged 60 years and older and its management in this part of the country.

    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.

    Incidence and etiology of facial fractures vary from region to region due to various constituents. This study was carried to evaluate the patterns and distribution of fractures in the facial region among different age groups of patients in both males and females caused due to various etiologies. This is a retrospective epidemiological study, which was performed on patients with fractures in the maxillofacial region during a period of 2005 to 2013 at Mamata Dental College and Hospital, Khammam, India. A total of 1,015 patients with 1,545 fractures were referred for treatment to department of oral and maxillofacial injuries surgery, of Mamata Dental College and Hospital, with a mean age of 31.19. The ratio of males (859):females (156) is 5.5:1. Injuries caused by motorbike injuries (34.9%) are highest. The highest frequency of fractures caused by various reasons is seen more in third decade (39%). Mandible (43.81%) is the most common fracture site in the face. Among soft tissue injuries most commonly seen are lacerations (43%). This study differentiates the etiological factors causing facial trauma in several age groups. Results of this study suggest outcomes indicate that more reliance on individual transport on motor vehicles has increased the frequency of facial bone fractures. Regardless of age, motor vehicle accidents were high in all age groups except the first decade of life and above 60 years of age when traffic accidents dominated. Thus effectiveness of current preventive measures is to be assessed, followed by instituting new guidelines for prevention and inflexible traffic rules shall be levied. More epidemiological surveys can, if encouraged to measure the frequency of fractures, better the world. PMID:26576235

    Objectives This retrospective study aims to evaluate the prevalence of maxillofacial trauma in a developing country, along with its pattern, etiology and management. Data for the present study were collected from the Department of Dentistry, ESIC Medical College and Post Graduate Institute of Medical Sciences and Research, Chennai in India. Materials and Methods The medical records of patients treated for maxillofacial injuries between May 2014 and November 2015 were retrospectively retrieved and analyzed for prevalence, pattern, etiology, and management of maxillofacial trauma. SPSS software version 16.0 was used for the data analysis. Results Maxillofacial fractures accounts for 93.3% of total injuries. The mean and standard deviation for the age of the patients were 35.0±11.8 years and with a minimum age of 5 years and maximum age of 75 years. Adults from 20 to 40 years age groups were more commonly involved, with a male to female ratio of 3:1. There was a statistically significantly higher proportion of males more commonly involved in accident and injuries (P <0.001). Conclusion The most common etiology of maxillofacial injury was road traffic accidents (RTA) followed by falls and assaults, the sports injuries seem to be very less. In RTA, motorized two-wheelers (MTW) were the most common cause of incidents. The majority of victims of RTA were young adult males between the ages of 20 to 40 years. The malar bone and maxilla were the most common sites of fracture, followed by the mandible. The right side of the zygomatic complex was the predominant side of MTW injury. The majority of the zygomatic complex fractures were treated by conservative management. Open reduction and internal fixation were performed for indicated fracture patients. PMID:27595083

  6. The role of maxillofacial radiologists in gunshot injuries: a hypothesized missile trajectory in two case reports

    Sansare, K; Khanna, V; Karjodkar, F

    2011-01-01

    Gunshot injuries are an emerging form of trauma that oral radiologists increasingly have to deal with. There are two main types of gunshot injuries: high-velocity and low-velocity bullet injuries. The outcome of high-velocity gunshot injury is usually fatal; however, a non-fatal low-velocity injury to the maxillofacial region is more likely to be encountered by the oral and maxillofacial radiologist. It is therefore important to up-to-date knowledge of ballistic science and its implications in the field of maxillofacial radiology. The ability of oral and maxillofacial radiologists to predict the missile trajectory will aid the assessment and localization of the damage caused by the bullet and its splinters. Predicting the missile trajectory may also be of help to law enforcement agencies and forensic scientists in determining the type of firearm used and direction of fire. This article, which examines two cases, attempts to highlight to the oral radiologist this emerging form of trauma and its implications. PMID:21159916

  7. Avoiding occlusal derangement in facial fractures: An evidence based approach

    Directory of Open Access Journals (Sweden)

    Derick Mendonca

    2013-01-01

    Full Text Available Facial fractures with occlusal derangement describe any fracture which directly or indirectly affects the occlusal relationship. Such fractures include dento-alveolar fractures in the maxilla and mandible, midface fractures - Le fort I, II, III and mandible fractures of the symphysis, parasymphysis, body, angle, and condyle. In some of these fractures, the fracture line runs through the dento-alveolar component whereas in others the fracture line is remote from the occlusal plane nevertheless altering the occlusion. The complications that could ensue from the management of maxillofacial fractures are predominantly iatrogenic, and therefore can be avoided if adequate care is exercised by the operating surgeon. This paper does not emphasize on complications arising from any particular technique in the management of maxillofacial fractures but rather discusses complications in general, irrespective of the technique used.

    Full Text Available Submental intubation is an interesting alternative to tracheostomy, especially when short-term postoperative control of airway is desirable with the presence of undisturbed access to oral as well as nasal airways and a good dental occlusion. Submental intubation with midline incision has been used in 10 cases from October 2008 to March 2010 in the Department of Oral and Maxillofacial Surgery, Manipal College of Dental Sciences, Mangalore. All patients had fractures of the jaws disturbing the dental occlusion associated with fracture of the base of the skull, or/and a displaced nasal bone fracture. After standard orotracheal intubation, a passage was created by blunt dissection with a haemostat clamp through the floor of the mouth in the submental area. The proximal end of the orotracheal tube was pulled through the submental incision. Surgery was completed without interference from the endotracheal tube. At the end of surgery, the tube was pulled back to the usual oral route. There were no perioperative complications related to the submental intubation procedure. Average duration of the procedure was less than 6 minutes. Submental intubation is a simple technique associated with low rates of morbidity. It is an attractive alternative to tracheotomy in the surgical management of selected cases of panfacial trauma.

    Recent epidemiological studies have demonstrated that significant associations exist between oral disease and diseases involving non-oral tissues. Occasionally, the roles may be reversed and the oral cavity can be severely affected by systemic disease originating in another part of the body. Renal secondary hyperparathyroidism is a common endocrinopathy that occurs as a consequence of chronic azotemic kidney disease. Renal osteodystrophy, the most dramatic clinical consequence of renal secondary hyperparathyroidism is uncommon, but can result in demineralization of maxillofacial bones, loosening of teeth, and pathological jaw fractures. The purpose of this report is to update the current understanding of the pathophysiology of this endocrine disease and to compare the oral manifestations of renal secondary hyperparathyroidism in humans and companion animals. A 50-year review of the veterinary literature was undertaken to examine the clinical presentation of renal osteodystrophy in dogs, and to determine what clinical consequences of renal secondary hyperparathyroidism have been reported in domestic cats.

    This study assessed the impact of oral and maxillofacial trauma and surgical treatment on the quality of life of patients. The study included 66 patients (age range 18-65 years) with facial fractures; 33 required surgical treatment and 33 required conservative (non-surgical) treatment. Quality of life was evaluated by applying the Oral Health Impact Profile questionnaire (OHIP-14) immediately after diagnosis of the trauma (T1), 30 days after surgery or trauma (T2), and 90 days after surgery or trauma (T3). For the control group (conservative treatment), there was a change in quality of life at T1 and T2. A change in quality of life was found for all of the surgical patients, regardless of the type of fracture and the observation period analyzed. There was no statistical difference when T1, T2, and T3 were compared in cases of zygomatic, Le Fort I, and nasal fractures, however there was an improvement in the quality of life of patients with mandibular fractures (P=0.0102) and multiple facial fractures (P=0.0097) at T3. Facial trauma caused the greatest impact on the quality of life of surgical patients at T1. The surgical treatment significantly improved quality of life for patients with mandibular and multiple facial fractures.

    Full Text Available Abstract Background Maxillofacial injuries pose a therapeutic challenges to trauma, maxillofacial and plastic surgeons practicing in developing countries. This study was carried out to determine the etiology, injury characteristics and management outcome of maxillofacial injuries at our teaching hospital. Patients and Methods A prospective hospital based study of maxillofacial injury patients was carried out at Bugando Medical Centre from November 2008 to October 2009. Data was collected using a structured questionnaire and analyzed using SPPS computer software version 11.5. Results A total of 154 patients were studied. Males outnumbered females by a ratio of 2.7:1. Their mean age was 28.32 ± 16.48 years and the modal age group was 21-30 years. Most injuries were caused by road traffic crushes (57.1%, followed by assault and falls in 16.2% and 14.3% respectively. Soft tissue injuries and mandibular fractures were the most common type of injuries. Head/neck (53.1% and limb injuries (28.1% were the most prevalent associated injuries. Surgical debridement (95.1% was the most common surgical procedures. Closed reduction of maxillofacial fractures was employed in 81.5% of patients. Open reduction and internal fixation was performed in 6.8% of cases. Complications occurred in 24% of patients, mainly due to infection and malocclusion. The mean duration of hospital stay was 18.12 ± 12.24 days. Mortality rate was 11.7%. Conclusion Road traffic crashes remain the major etiological factor of maxillofacial injuries in our setting. Measures on prevention of road traffic crashes should be strongly emphasized in order to reduce the occurrence 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.

    Despite the progress made in tumor and reconstructive surgery of the maxillofacial region, postoperative problems, such as malnutrition and dysfunction of the oral-oesophageal tract are still encountered. Nutrition via a nasogastric tube often complicates the rehabilitation process of these patients. Percutaneous endoscopic gastronomy (PEG), as opposed to nasogastral feeding, is presented. The technique, possible long-term complications, and the easy usage of the mechanical pump system, are presented. In our study of 40 patients, PEG, objectively, proved useful for functional, esthetic, practical, economical, and psychological reasons.

    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.

    The purpose of this article is to analyze the incidence, demographic distribution, type, and etiology of all facial fractures treated by the Department of Oral and Maxillofacial Surgery in A Coruña University Hospital (Spain) from 2001 to 2008. A descriptive and analytic retrospective study evaluated 643 patients treated for facial fracture (excluding nasal and dento-alveolar) by the Department of Oral and Maxillofacial Surgery in A Coruña University Hospital from January 2001 to December 2008. Five parameters were studied: year of the injury, gender, age, fracture type, and etiology. Six hundred and forty-three patients with 793 fractures were included. Of these, 83.2% were males and 16.8% were females. The patients' age ranged between 18 months and 89 years, with a mean of 37.6 and a median of 33. The major cause of injury was traffic accidents (27%), followed by assaults (20.5%), accidental traumas (20.1%), sports (11%), syncopes (7.8%), rural accidents (6.1%), industrial accidents (5.1%), and suicide attempts (0.3%). In 1.1% of the patients, it was impossible to verify the etiology. The etiology of facial fractures varies from one country to another, depending on the cultural, environmental, and socioeconomic factors. In our study, the most common cause was traffic accidents, closely followed by assaults. The number of fractures due to traffic accidents has decreased in the last 3 years. Rural accidents accounted for a significantly higher percentage of fractures than that observed in other series. The number of fractures receiving a surgical treatment from 2005 to 2008 has progressively decreased.

    The aim of this study was to assess the characteristics of patients with coronoid fractures treated in two European centres over 10 years and to briefly review the literature. This study is based on 2 systematic computer-assisted databases that have continuously recorded patients hospitalized with maxillofacial fractures and surgically treated in two European centres between 2001 and 2010. During the 10 years, 1818 patients and 523 patients with maxillofacial fractures were admitted to the two centres respectively: 21 patients (16 males, 5 females) were admitted with 21 coronoid fractures and 28 associated maxillofacial fractures. A mean age of 42.1 years was observed. The fractures were mainly the result of motor vehicle accidents, followed by assaults and falls. The most frequently observed associated maxillofacial fracture was a zygomatic fracture (13 fractures). In both centres, mandibular coronoid fractures are treated unless a severe dislocation of the fractured coronoid is observed or a functional mandibular impairment is encountered. Conservative treatment can be used, together with the open reduction and internal fixation of associated fractures. The crucial point is to prevent ankylosis, which may be prevented by correct and early postoperative physiotherapy and mandibular function.

    There is clearly a need for maxillofacial prosthetic materials with improved properties. The chlorinated polyethylenes are thermoplastic elastomers which have particularly promising properties, and were used by us to prepare improved maxillofacial prostheses. Suitable CPE resins were compounded with other polymers and with pigments on a heated rubber mill to form thin sheets in a variety of shades. These were heated at 190 degrees C for 10 min and placed between heated linotype mold halves. The prosthesis was formed in a hand press. Sometimes heating and pressing were repeated. After cooling in water, the prosthesis was removed and hand-shaded with oil-soluble dyes. Physical properties were evaluated using standard techniques; skin irritation studies were conducted by 14-day insult patch tests on rabbits. Clinical evaluations were conducted on human volunteers. Parallel evaluations were conducted on commerically available materials for comparison. The CPE was superior to all of the three commerical materials in most properties, and comparable to the better of the three in the remaining properties. On balance, CPE was significantly superior. Early results indicate that the materials and techniques required are easily handled in the dental lab and that the final prosthesis has excellent aesthetic and patient acceptability.

    Full Text Available In the treatment of mandibular condyle fracture, conservative treatment using closedreduction or surgical treatment using open reduction can be used. Management of mandibularcondylar 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 intoconsideration the presence of teeth, fracture height, patient’sadaptation, patient’s masticatorysystem, disturbance of occlusal function, and deviation of the mandible. In the past, closedreduction with concomitant active physical therapy conducted after intermaxillary fixationduring the recovery period had been mainly used, but in recent years, open treatment ofcondylar fractures with rigid internal fixation has become more common. The objectiveof this review was to evaluate the main variables that determine the choice of an open orclosed method for treatment of condylar fractures, identifying their indications, advantages,and disadvantages, and to appraise the current evidence regarding the effectiveness ofinterventions that are used in the management of fractures of the mandibular condyle.

    Full Text Available Abstract Background Malnutrition is a problem for many older people recovering from a hip and other major fractures. Oral supplementation with high calorie high protein nutrients is a simple intervention that may help older people with fractures to improve their recovery in terms of rehabilitation time, length of hospital stay and mortality. This paper reports a pilot study to test the feasibility of a trial initiated in a hospital setting with an oral supplement to older people with recent fractures. Method A randomized controlled trial with 44 undernourished participants admitted to a hospital following a fracture. The intervention group (n = 23 received a high calorie high protein supplement for forty days in addition to their diet of choice. The control group (n = 21 received high protein milk during their hospital stay in addition to their diet of choice and their usual diet when discharged from hospital. Results All participants were women and their mean age was 85.3 (± 6.1 years. Twenty nine (65% participants had a hip fracture. At baseline no differences were measured between the two groups regarding their nutritional status, their cognitive ability or their abilities in activities of daily living. There were no significant differences between the intervention and control group with reference to nutritional or functional parameters at 40 day and 4 month follow-ups. Median length of stay in hospital was 18.0 days, with 12 participants being readmitted for a median of 7.0 days. Conclusion It is feasible to perform a randomised trial in a hospital and community setting to test the effect of an oral high energy high protein supplement for older people. Due to the limited number of participants and incomplete adherence with use of the supplements no conclusion can be drawn about the efficacy or effectiveness of this intervention.

    2015-01-01

    Bisphosphonate-related osteonecrosis of the maxillae may be an important complication of long-term osteoporosis treatment. The possibility of osteonecrosis of the maxillae in patients exposed to nitrogenated bisphosphonates was first described in 2003. Since then, case reports and retrospective studies have demonstrated higher percentages of occurrence of osteonecrosis in patients who have used or are using bisphosphonates. Although this complication may be spontaneous, invasive oral procedures have a role as risk factors associated with dental procedures such as tooth extractions and other bone operations. In addition, tooth infections and periodontal disease have been reported to be the main risk factors for development of bisphosphonate-induced osteonecrosis of the maxillae. For this reason, dentists, general clinicians, orthopedists, geriatricians and oral-maxillofacial surgeons need to be aware of this problem and work in a multidisciplinary environment, thereby stimulating early diagnosis and prevention of further potential cases.

    2016-09-01

    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.

    During a 33 month period, maxillofacial injuries resulting from terrorist attacks in Israel were compared with non-terror trauma maxillofacial injuries. Files of patients hospitalized from October 1, 2000 to June 30, 2003 were obtained from the Israel National Trauma Registry. Data were evaluated and compared with a hospitalized non-terror related trauma population within the same period. A literature survey was also conducted. Terror casualties totaled 1,811. In 493 patients with facial injuries, 322 had soft facial tissue injuries (excluding eyes and ears), and 104 had hard tissue injuries of the maxillofacial complex. A significantly higher prevalence was found in terror casualties (explosions and gunshots) compared with non-terror related casualties. Most suffered multiple injuries. Maxillofacial terror casualties experience a unique epidemiology, with more severe injuries and higher prevalence of soft and hard tissue injuries. Preparedness and awareness to the unique pattern of injuries are needed when terrorists strike.

    Full Text Available BACKGROUND Anaesthetic management of patients with oromaxillofacial surgeries poses quite a few challenges to both anaesthesiologist and operating surgeons. This is because the corrective procedure demands fixation of fractures, repair of soft tissue injuries and maintaining occlusion all without compromising the cosmetic aspect. Though securing the airway takes the precedence, it is of paramount importance that it should not interfere with the surgical techniques. METHODS Seventy one patients of maxillofacial injuries, operated over a period of five years between February 2011 and December 2015 in Indira Gandhi Medical College Hospital at Puducherry were reviewed. All patients were reviewed in relation to age, type of injury, etiology, bones involved and method of airway management. RESULTS The major etiology of injuries were road traffic accidents (79%. Majority of patients were young in the age group of 21-40 years (55%. Fracture mandible (46% was the most common injury. Airway secured by nasotracheal route with direct visualization of vocal cords was the most common (90%, followed by submental route (10%. CONCLUSION This analysis showed in maxillofacial procedures, trauma is the leading cause in this part of India also. Male preponderance, maximum injuries are seen in third and fourth decade of life and other findings that are correlating well with other studies. Nasotracheal intubation is the method of choice in securing the airway during the maxillofacial procedures. Submental intubation can be considered as a viable option when nasotracheal intubation is not possible due to the involvement of base of the skull or midfacial fractures.

    Establish the panorama of primitive oto-rhino-laryngology and cervico-maxillofacial tumors diagnosed at a reference center in Togo. We conducted a retrospective, descriptive study of cancers diagnosed at the ORL and cervico-maxillofacial surgery department of the CHU Sylvanus Olympio of Lomé. It was conducted over a period of 10 years (1 January 2005 - 31 December 2014). ORL and cervico-maxillofacial tumors account for 0.48% of consultations and 15.3% of all ORL tumors. The average age of patients was 47 years, ranging from 3 months to 86 years. We noted a male predominance; the sex ratio was 1.45. Drinking alcohol and smoking tobacco prevailed in the cancer of the larynx. Upper aerodigestive tract (UAT) tumors accounted for 64,8%, with a prevalence of cancers of the oral cavity (36,2% of UAT), followed by cancers of the oropharynx (18,5% of UAT) and finally by cancers of the larynx (18,1% of UAT). Primary malignant cervical adenopathies accounted for 18%. The rarest lesions were cancers of the ear and of maxillomandibular bone tissue (2.24% each). Histology was dominated by squamous cell carcinoma (61.4%) followed by non-Hodgkin lymphoma (23.2%). ORL and cervico-maxillofacial tumors are frequent in Togo and can be diagnosed at any age. The predominant tumor types reported are those of the oral cavity, pharynx and primary malignant cervical adenopathies.

    Full Text Available The aim of the current investigation was to evaluate the fracture resistance of one-piece zirconia oral implants with and without all-ceramic incisor crowns after long-term thermomechanical cycling. A total of 48 implants were evaluated. The groups with crowns (C, 24 samples and without crowns (N, 24 samples were subdivided according to the loading protocol, resulting in three groups of 8 samples each: Group “0” was not exposed to cyclic loading, whereas groups “5” and “10” were loaded with 5 and 10 million chewing cycles, respectively. This resulted in 6 different groups: C0/N0, C5/N5 and C10/N10. Subsequently, all 48 implants were statically loaded to fracture and bending moments were calculated. All implants survived the artificial aging. For the static loading the following average bending moments were calculated: C0: 326 Ncm; C5: 339 Ncm; C10: 369 Ncm; N0: 339 Ncm; N5: 398 Ncm and N10: 355 Ncm. To a certain extent, thermomechanical cycling resulted in an increase of fracture resistance which did not prove to be statistically significant. Regarding its fracture resistance, the evaluated ceramic implant system made of Y-TZP seems to be able to resist physiological chewing forces long-term. Restauration with all-ceramic single crowns showed no negative influence on fracture resistance.

    Currently, imaging techniques such as Computed Tomography with three-dimensional reconstruction (3D) and Magnetic Resonances are being routinely used in pre-surgical planning in all fields of medicine. Nowadays, virtual three-dimensional images, commonly displayed on two-dimensional surfaces, such as the computer screen, can be used to produce rapidly prototyped models, with excellent dimensional accuracy and fine reproduction of anatomical structures, providing professionals with the ability to use the biomodel in planning and simulating medical and dental procedures (oral and maxillofacial surgery, making individualized facial implants and prostheses, measurements and previous adaptations of prefabricated fixation plates), thus contributing to considerable reductions in surgical time and consequently the duration of anesthesia, minimizing infection risks and reducing hospital costs. In this report, we describe a case of surgical planning and treatment of bilateral atrophic mandibular fracture, in which, for surgical planning, authors used Rapid Prototyping as an adjunct tool, considering the advantages already outlined.

    From 2002 to 2006, more than 117,000 facial fractures were recorded in the U.S. National Trauma Database. These fractures are commonly treated with open reduction and internal fixation. While in place, the hardware facilitates successful bony union. However, when postoperative complications occur, the plates may require removal before bony union. Indications for salvage versus removal of the maxillofacial hardware are not well defined. A literature review was performed to identify instances when hardware may be salvaged. Articles considered for inclusion were found in the PubMed and Web of Science databases in August 2014 with the keywords maxillofacial trauma AND hardware complications OR indications for hardware removal. Included studies looked at human patients with only facial trauma and miniplate fixation, and presented data on complications and/or hardware removal. Fifteen articles were included. None were clinical trials. Complication data were presented by patient, fractures, and/or plate without consistency. The data described 1,075 fractures, 2,961 patients, and 2,592 plates, nonexclusive. Complication rates varied from 6 to 8% by fracture and 6 to 13% by patient. When their data were combined, 50% of complications were treated with plate removal; this was consistent across the mandible, midface, and upper face. All complications caused by loosening, nonunion, broken hardware, and severe/prolonged pain were treated with removal. Some complications caused by exposures, deformities, and infections were treated with salvage. Exposed plates were treated with flaps, plates with deformities were treated with secondary procedures including hardware revision, and hardware infections were treated with antibiotics alone or in conjunction with soft-tissue debridement and/or tooth extraction. Well-designed clinical trials evaluating hardware removal versus salvage are lacking. Some postoperative complications caused by exposure, deformity, and/or infection may be

    Full Text Available Fractures of severely atrophic (height < 10 mm edentulous mandibles are infrequent and challenging to manage. Factors such as sclerotic bone and decreased vascularity combined with systemic diseases complicate the management of such fractures. Osteogenesis imperfecta (OI is a heterogeneous group of inherited disorders of type I collagen metabolism. Patients with OI characteristically present with histories of long bone fractures, deformities, blue sclerae, and opalescent dentin. However, fractures of the facial skeleton are rare. Bisphosphonate therapy has been proven to effectively reduce the fracture risk in patients with OI. The purpose of this clinical report is to present an unusual case of spontaneous fracture of the atrophic mandible in a patient with OI. Despite open reduction and internal fixation (ORIF with miniplate osteosynthesis, the patient developed a second fracture at a screw placement site distal to the first fracture. The patient was successfully treated with ORIF using locking reconstruction plates fixed in the symphyseal and angle regions. Bone healing following ORIF was normal, and no clinical sign of osteonecrosis as a result of bisphosphonate therapy was observed. Patients with OI can present with spontaneous fractures of already weakened mandibles. Although such fractures can be managed with care using established protocols, further research is required to examine the effects of concomitant medication, such as bisphosphonates.

    Full Text Available Kite flying is a popular sport among children. Most of the injuries sustained during kite flying are due to falls, cuts, head injuries, or fractures. Injury with innocent-looking kite string in the maxillofacial region is rare. A 4½-year-old male patient with a clean cut, deep incised wound exposing the fat and muscle was treated with primary closure. Kite flying is associated with injuries ranging from simple cuts to grave lacerations or head trauma. The severity of lacerations depends on the abrasive material that is often placed on the string of the kite to increase its ability to cut. Injuries related to kite flying are preventable. Preventive measures include choosing a safe location and the need for increasing awareness about the possible effects of such a sport.

    2014-11-01

    Maxillofacial and traumatic dentoalveolar injuries can cause pain and inflammation, and reduce function of the mouth, impacting a cat's quality of life. Many traumatically induced feline fractures have been reported to involve the mandible or skull and, in cats with maxillofacial trauma, traumatic dentoalveolar injuries are particularly prevalent. Traumatic dentoalveolar injuries can also often be found in otherwise healthy cats. Some traumatic dentoalveolar injuries require emergency treatment; timely recognition and managment is therefore important for achieving the optimal outcome. Multiple approaches exist for the management and repair of maxillofacial traumatic injuries. However, those for traumatic dentoalveolar injuries may be more limited. This review is aimed at feline and general practitioners, as well as veterinarians with expertise in dentistry. The authors draw on their clinical experience and evidence from the literature, where appropriate, to produce an overview of foundation guidelines. It is hoped that this will serve as a stimulus for deeper consideration as to what constitutes 'best practice' principles for cats with traumatic dentoalveolar and maxillofacial injuries. © ISFM and AAFP 2014.

    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.

    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.

    It is a difficult to carry biological tissue regeneration and functional reconstruction for oral and maxillofacial deformities,especially for dental tissue defects. This project was designed to regenerate tooth , repair the defects of facial bones and reconstruct the function of salivary glands that providing the support for oral cavity. By using gene transfer and salivary gland endoscopy, the new techniques were developed for diagnosis and treatment of obstructive salivary gland diseases and for recovery of irradiation-induced salivary gland dysfunction. We proposed a new concept called as “biological roots” by using of stem cells and tissue engineering technology, the biological roots with mastication function was successfully regenerated in the swine; based on tooth development strategy, new ways for whole tooth regeneration were established and the new seed cells was discovered. Key technologies, parameters and new devices were obtained for development of jaw osteodistraction to improve the complex maxillofacial defects effectively by endogenous jaw bone regeneration. This research and its application in clinic improved tissue regeneration and restoration of oral and maxillofacial tissue,normalized the diagnosis and treatment, and promoted the development of oral and maxillofacial surgery and translational medicine.%针对以牙齿为中心的口腔颌面组织缺损畸形缺乏生理性修复及功能重建困难的问题,"口腔颌面组织修复及功能重建技术的研究及应用"项目组,围绕牙齿,颌面骨及提供口腔支撑环境分泌唾液的涎腺进行了较系统、全面的专题研究.利用涎腺内镜及基因转导技术诊治阻塞性涎腺疾病,恢复涎腺功能,重建放射损伤涎腺功能.提出"生物牙根"理念,利用干细胞与组织工程技术,成功再生了具有咀嚼功能的生物牙根;基于牙发育提出牙再生新方式并发现种子细胞.确立颌骨牵张成骨关键技术及参数,通过数字测量

    Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

    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.

    The basic principles of expert medical witness testimony of the maxillofacial region are described. The specific anatomic characteristics of the region are emphasized, especially in view of the fact that face is the most exposed part of the human body. Post-traumatic deformities of the maxillofacial region involve soft tissues of the face and mouth as well as bony structures of the viscerocranium and teeth. Endured physical pain, lessening of life activities, disfigurement and requirement of assistance by third person are separately described as an important part of expert medical witness testimony of the maxillofacial region. The number of lawsuits raised against physicians has significantly increased in the past several years, more often in cases where the patients are dissatisfied with the results of cosmetic surgery, especially when these procedures are performed on the face.

    Color information from different color-measuring systems varies during color matching in maxillofacial prosthetics. We studied the hypothesis that a non-contact measuring system and 4 contact color-measuring instruments perform comparably in accuracy and precision on measurements of pigmented maxillofacial elastomer specimens having human skin colors. Measurement comparisons in accuracy on opaque standard color patches were made in Phase I. In Phase II, the system with the best accuracy was used as the reference instrument, and comparisons in accuracy and precision on elastomer specimens were made. The CIEDE2000 color difference formula was used. Repeated-measures ANOVA with Tukey testing and linear regression analysis for CIELAB and color differences among the instruments were performed. The contact measuring systems perform differently in accuracy, possibly due to edge loss and other factors, but performed comparably in precision with the non-contact measuring instrument. This non-contact system is recommended for color measurement of maxillofacial prosthetic materials.

Among the non-OMFS patients with such fractures, 42 (48.3% patients had trismus preoperatively and two retained trismus postoperatively. Lack of proper preoperative CT images, inadequate postoperative follow-up protocol, and/or neglect by patients and medical staff could influence the outcomes of ZMC fracture involving the TMJ. We make recommendations for reducing the risk of complications subsequent to ZMC fracture involving the TMJ.

The following variables were analyzed: gender, age range, time of occurrence (date and hour, etiology, presence of associated fractures, type of treatment and time of hospitalization. Results: The results showed that males were more frequently affected than females (83.1%, with predominance in the 21-30 age range (40.7%. Most cases were treated on Saturdays and Sundays (40.6% and at night (30.5%. Falls, (28.8%, interpersonal violence (23.7% and motorcycle accidents (23.7% were the main etiologies. Five patients (8.5% presented fractures in other facial bones and the most frequent treatment was the intermaxillary retention with stainless steel wire (50.8%. The mean hospitalization time was 5.28 days.Conclusions: The prevalence of mandibular fractures is higher in the male gender, during the third decade of life; falls were the main etiologic factor and most cases occurred during the weekend.

    The skull base is uniquely placed to absorb anteriorly directed forces imparted either via the midfacial skeleton or cranial vault. A variety of skull base fracture classifications exist. Less well understood, however, is fracture extension beyond the anterior cranial fossa (ACF) into the middle and posterior cranial fossae. The cases of 81 patients from two UK major trauma centres were studied to examine the distribution of fractures across the skull base and any relationship between the vector of force and extent of skull base injury. It was found that predominantly lateral force to the craniofacial skeleton produced a fracture that propagated beyond the ACF into the middle cranial fossa in 77.4% of cases, significantly more (P<0.001) than for predominantly anterior force (12.0%). Fractures were significantly more likely to propagate into the posterior fossa with a lateral vector of impact compared to an anterior vector (P=0.049). This difference in energy transfer across the skull base may, in part, be explained by the local anatomy. The more delicate central ACF acts as a 'crumple zone' in order to absorb force. Conversely, no collapsible interface exists in the lateral aspect of the ACF, thus the lateral ACF behaves like a 'buttress', resulting in increased energy transfer.

    Dental intrusion and avulsion, crown fracture and mandibular fractures are important dentofacial complications in patients with epilepsy-related traumas. The objective of the present study was to describe the occurrence of orofacial injuries in patients with epilepsy. One hundred and nine consecutive patients (60 women; mean age 38.81 ± 14 years), treated for refractory epilepsy (45 with extratemporal epilepsy and 64 with temporal epilepsy) at the outpatient clinic of our University Hospital, were included in the present study. Orofacial injury occurring as a direct result of a seizure was determined by clinical examination and interview. In addition, seizure frequency, use of medication, and the occurrence and type of injury to other parts of the body, were documented. We employed regression analyses to investigate the association between teeth fractures and frequency of seizures. The majority of injuries were crown fractures (42 subjects), followed by mandibular fractures (eight subjects) and tooth avulsion (eight subjects). Sixteen patients had more than two fractured teeth. Patients with mandibular trauma also suffered concomitant injuries (teeth fracture, avulsion and dislocation). The number of fractured teeth was associated with seizure frequency (r(2) = 0.59, p dentoalveolar and maxillofacial injuries in patients with poorly controlled epileptic seizures.

    We explored the relation between the causes of facial injuries in equestrians and the presence or absence of associated injuries. Over a 5-year period we retrospectively reviewed all patients who presented to the John Hunter Hospital, New South Wales, with facial injuries that had resulted from activity with horses. We analysed the rates of hard and soft tissue injuries, and of associated injuries by sex and mechanism. A total of 85 patients were included (50 female and 35 male) with an age range of 2-88 years. There was a significant difference in the rate of maxillofacial and associated injuries when groups were analysed for sex and mechanism of injury. Facial injuries caused by falling from a horse were more often associated with other injuries in men than in women (p<0.05), and men were 4 times more likely to present with associated injuries than women (OR 3.9; 95% CI 1.1 to 14) We also found significant differences in the rates of facial fracture. Women who had been kicked by a horse were more likely to sustain bony injuries than men (p<0.05). Our data confirm the association between kicks and facial fracture, and this may provide an impetus for the development of appropriate protective equipment. Patients who sustain facial injuries when falling from a horse often present with associated injuries and this has practical implications for clinicians involved in their management.

    Patients surgically treated for infection after extremity fractures are typically discharged with a 6- to 12-week antibiotic regimen. Intravenous (IV) antibiotics are associated with significant cost and potential complications of deep vein thrombosis, line clotting, and sepsis. Many of the pathogens that cause musculoskeletal infection have both oral (PO) and IV antibiotic options with adequate bioavailability and antibacterial effect, yet IV antibiotics remain the standard of care absent evidence that PO options are clinically as efficacious. The POvIV study is a prospective, multicenter, randomized trial to compare PO with IV antibiotic therapy in patients with postoperative wound infections after extremity fractures. Patients between the ages of 18 and 84 who have a culture-positive surgical site infection after internal fixation for fracture repair or arthrodesis are approached for this study, and if they provide consent, are randomly assigned to receive either PO or IV antibiotics. Antibiotic selection is based on culture and sensitivity results. Randomization determines the route of administration. Patients are followed for 1 year after study enrollment. This study will be the largest prospective randomized trial to evaluate the safety and effectiveness of PO antibiotic use for treatment of postoperative wound infections. Results will inform clinician decisions on antibiotic delivery in patients with postoperative wound infections.

    To evaluate the frequency and causes of dental and maxillofacial trauma in hospitalized patients. From January 1, 2000 to December 31, 2003, data from hospitalized trauma patients in a level 1 trauma center in Israel were analyzed according to age, gender, time, place, and cause of injury. Maxillofacial and tooth injuries were separated and further analyzed according to the above parameters. The analysis was based on data from the Israel Trauma Registry (ITR). Of all 14 040 trauma patients, 1038 (7.4%) involved maxillofacial or dental injuries. Common causes of injury were motor vehicle crashes (41%), falls (27%) and intentional injuries (23%). Fifty percent occurred on the street/road, 17% at home and 14% in public buildings. Surgery was required in 55.5% of all maxillofacial injuries. Males were hospitalized three times more than females, and young people, ages 19-28, were at greatest risk (30.2%). Oral and maxillofacial trauma is common, requiring dental health training for primary caregivers.

    Full Text Available Maintenance of proper oral hygiene by dental plaque elimination is one of the most important factors affecting the healing process in postoperative oral wounds. Propolis is a substance produced by bees. Ethanolic extract of propolis has bactericidal, fungicidal, anti-inflammatory, and antioxidative properties. Moreover, it can scavenge free radicals. The purpose of this paper is to demonstrate the efficacy of a gel containing 3% of ethanolic extract of Brazilian green propolis (EEP-B when used for maintaining oral hygiene in patients with postoperative oral mucosal wounds. The hygiene was assessed using API, OHI, and SBI followed by microbiological examinations. The patients were divided into two groups. Group 1 consisted of those who used a gel containing EEP-B for oral hygiene, and group 2 consisted of those who used a gel without EEP-B. Although improved oral hygiene was noted in both groups, the improvement was markedly greater in the group using gel containing EEP-B. Summing up the results of microbiological examinations, EEP-B has beneficial effect on mouth microflora in postoperative period. Propolis preparations used for oral hygiene allow eliminating microorganisms of pathogenic character and physiological flora microorganisms considered as being opportunistic, with no harmful influence on physiological microflora in oral ecosystem.

  15. Circummandibular Wires for Treatment of Dentoalveolar Fractures Adjacent to Edentulous Areas: A Report of Two Cases.

    Maloney, Karl

    2015-09-01

    In general, dentoalveolar fractures are a common injury seen in emergency departments, dental offices, and oral and maxillofacial surgery practices. These injuries can be the result of direct trauma or indirect trauma. Direct trauma more often causes trauma to the maxillary dentition due to the exposure of the maxillary anterior teeth. Indirect trauma is usually the result of forced occlusion secondary to a blow to the chin or from a whiplash injury. Falls are the most common mechanism of injury seen in the pediatric group. In adolescents, many of these fractures are sustained during sporting activities. However, the use of mouth guards and other protective equipment has decreased this number. Most adult injuries are caused by motor vehicle accidents, contact sports, falls, bicycles, interpersonal violence, medical/dental mishaps, and industrial accidents. Early intervention to reduce and stabilize the fracture is required to establish a bony union and ensure correct function. Most dentoalveolar fractures have bilateral stable adjacent dentition and are treated with a closed technique utilizing an acid-etch/resin splint followed by splint removal at 4 weeks. Other inferior stabilization treatments used are arch bars and other wiring techniques. It is widely accepted that semirigid stabilization techniques, such as an acid-etch/resin splint or wiring procedures, are adequate to treat dentoalveolar fractures. This is in contrast to the treatment of mandible fractures where AO principles of rigid fixation are often followed. Fractures that are unable to be reduced sometimes necessitate an open reduction followed by internal fixation, sometimes using a secondary splint for mobile teeth. In those rare cases when there are not stable adjacent teeth bilaterally other modalities must be considered. In the present report, two cases are presented where circummandibular wires were used to treat fractured mandibular dentoalveolar segments adjacent to edentulous areas.

    Condyle fractures represent 20% to 30% of all mandibular fractures and are thus among the most common facial fractures. The fracture pattern can vary greatly and may occur anywhere along the line from the sigmoid notch to the mandibular angle. The main problems are access, difficulty in repositioning the extremely slender fragments, and fixation of the condyle.Eighty-seven patients were diagnosed with condylar neck or condylar base fractures from January 2007 to December 2009 in the Department of Oral & Maxillofacial Surgery of Kyung Hee University Dental Hospital. In this study, we included 35 patients who underwent open surgery and a total of 28 patients who were treated using a retromandibular transparotid approach.Surgical treatment aims were anatomic repositioning and rigid fixation of the fragments, occlusal stability, rapidly return to function, maintenance of vertical ramus dimension, no airway compromise, and reduced long-term temporomandibular joint dysfunction. Considering the high rate of occurrence of condylar fracture and the importance of the condylar as a growth center of the mandible, extraoral approaches for the open reduction of condylar fractures are considered effective and can be used widely.Short access route, easy reduction, short operating time, and stable postoperative occlusion are the advantages of the retromandibular transparotid approach. Also, there was no permanent damage from facial nerve injury, salivary leakage, or preauricular hypoesthesia. Therefore, the retromandibular transparotid approach is considered a safe and effective method for patients with a condylar neck or condylar base fracture classified according to the Strasbourg Osteosynthesis Research Group's classification, who require surgical treatment with an extraoral approach.

    Diplopia is a symptom that is frequently associated with orbital wall fractures. The aim of this article was to present the incidence and patterns of diplopia after orbital wall blow-out fractures in 2 European centers, Turin and Amsterdam, and to identify any correlation between this symptom and such fractures. This study is based on 2 databases that have continuously recorded data of patients hospitalized with maxillofacial fractures between 2001 and 2010. On the whole, 447 patients (334 males, 113 females) with pure blow-out orbital wall fractures were included. The most frequently involved orbital site was the floor (359 fractures), followed by medial wall (41 fractures) and lateral wall (5 fractures). At presentation, 227 patients (50.7%) had evidence of diplopia. In particular, in most patients, a diplopia in all directions was referred (78 patients). Statistically significant associations were found between diplopia on eye elevation and orbital floor fractures (P diplopia and medial wall fractures (P diplopia on eye elevation and horizontal diplopia at presentation could be useful clinical indicators orbital floor and medial wall fractures, respectively.

    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.

    Full Text Available In this paper we present the aspect of a mandibular giant cell granuloma in spiral computed tomography-based three-dimensional (3D-CT reconstructed images using computer graphics, and demonstrate the importance of the vascular protocol in permitting better diagnosis, visualization and determination of the dimensions of the lesion. We analyzed 21 patients with maxillofacial lesions of neoplastic and proliferative origins. Two oral and maxillofacial radiologists analyzed the images. The usefulness of interactive 3D images reconstructed by means of computer graphics, especially using a vascular setting protocol for qualitative and quantitative analyses for the diagnosis, determination of the extent of lesions, treatment planning and follow-up, was demonstrated. The technique is an important adjunct to the evaluation of lesions in relation to axial CT slices and 3D-CT bone images.

    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.
