Full Text Available Thorough planning and execution is the key for successful treatment of dentofacial deformity involving surgical orthodontics. Presurgical planning (paper surgery and model surgery are the most essential prerequisites of orthognathic surgery, and orthodontist is the one who carries out this procedure by evaluating diagnostic aids such as crucial clinical findings and radiographic assessments. However, literature pertaining to step-by-step orthognathic surgical guidelines is limited. Hence, this article makes an attempt to provide an insight and nuances involved in the planning and execution. The diagnostic information revealed from clinical findings and radiographic assessments is integrated in the "paper surgery" to establish "surgical-plan." Furthermore, the "paper surgery" is emulated in "model surgery" such that surgical bite-wafers are created, which aid surgeon to preview the final outcome and make surgical movements that are deemed essential for the desired skeletal and dental outcomes. Skeletal complexities are corrected by performing "paper surgery" and an occlusion is set up during "model surgery" for the fabrication of surgical bite-wafers. Further, orthodontics is carried out for the proper settling and finishing of occlusion. Article describes the nuances involved in the treatment of Class III skeletal deformity individuals treated with orthognathic surgical approach and illustrates orthodontic-orthognathic step-by-step procedures from "treatment planning" to "execution" for successful management of aforementioned dentofacial deformity.

Impaction of maxillary canines is a common orthodontic anomaly that causes facial and dentoalveolar system problems, both functional and esthetic. A combination of surgery and orthodontics is important in bringing impacted canines to their ideal position in the dental arch. In this case report of a 14-year-old patient with impacted right and left maxillary canines, the crowns of these teeth were surgically exposed, brackets were bonded, and light orthodontic forces were delivered for 2 years to align the teeth in the dental arch.

To describe a multidisciplinary treatment approach that includes corticotomy, orthodontic force and orthognathic surgery for the management of skeletal Class III surgical cases. The main advantage of the combined techniques is a reduction in treatment time for young adult patients. Accelerated Osteogenic Orthodontics (AOO) was delivered to three young adult patients during their pre-surgical orthodontic treatment. After aligning and levelling the dental arches, a piezosurgical corticotomy was performed to the buccal aspect of the alveolar bone. Bone graft materials were used to cover the decorticated area and soft tissue flaps were replaced. The mean time for extraction space closure was 5.4 ± 1.3 months and the mean time for pre-surgical orthodontic treatment was 12.0 ± 0.9 months. The average total treatment time was 20.4 ± 2.4 months. A pre-existing bony fenestration in the buccal cortex adjacent to the right lateral incisor root apex of Case 1 was corrected. The facial aesthetics of three patients improved following multidisciplinary treatment. This approach may be an efficient method for the orthognathic patient who desires a reduced treatment time, but further clinical research is required.

This article reports a clinical case involving an 8-year-old boy with two mesiodentes. The supernumerary teeth caused both a functional alteration (malocclusion) and an esthetic one (interincisal diastema), both of which affected his quality of living. Surgical removal of the supernumerary teeth and orthodontic follow-up was proposed, in agreement with the treatment established in the literature. This treatment produced satisfactory results in terms of both esthetics and functionality.

Noonan syndrome, characterized by short stature, facial anomalies, and congenital heart defects, may also be associated with hematopoietic disorders. Craniofacial anomalies in affected patients include hypertelorism and severe open bite associated with masticatory dysfunction. We treated a Noonan syndrome patient with a skeletal open bite. Surgical orthodontic treatment including two-jaw surgery established a good occlusal relationship after correction of severe anemia. Both upper and lower incisors were moved to upright positions, while clockwise rotation of the palatal plane and decreased mandibular plane angle were accomplished. Lower masticatory activity may affect posttreatment occlusion in such cases.

A case of bilateral 'double teeth' is described. The patient, aged 8 at initial presentation, was unhappy with the appearance of his two abnormally large upper central incisor teeth. Endodontic treatment was carried out on both teeth followed by surgical splitting and the removal of half of each so as to leave two reasonably-shaped central incisors. Comprehensive orthodontic treatment was then carried out to align the teeth and reduce the overjet, following which the central incisors exhibited no increased mobility or any periodontal problems.

This article describes the treatment of an adult male with vertical maxillary excess, excessive gingival display on smiling, a convex profile, proclined upper and lower incisors, and crowded lower anteriors with severe lip incompetence. The therapy included stages: (1) Pre surgical orthodontics- leveling and aligning of the maxillary and mandibular arch with closure of all extraction spaces. (2) Surgical phase-Lefort I osteotomy for superior maxillary impaction, 5 mm of anterior and 3 mm of posterior impaction ofmaxilla was done. (3) Post surgical orthodontics for finishing and detailing. The treatment lasted 16 months; improved facial esthetics significantly; and resulted in a normal occlusion, overjet, and overbite.
Full Text Available This case report describes the surgical-orthodontic treatment of a 26-year-old post-pubertal male patient with a Class III dentofacial deformity. In the pre-surgical orthodontic phase of treatment, a reverse overjet of 5.5 mm was created and arch compatibility was obtained. A mandibualr set back with BSSO was performed during surgery to restore ideal overjet, overbite, occlusion and optimal esthetics. After 1 year of treatment, the results remained stable.
Full Text Available Maxillary permanent incisors impaction is not a frequent case in dental practice, but its treatment is challenging because of its importance to facial esthetics. Supernumerary teeth are the main cause of impaction of upper incisors. Supernumerary teeth when present can cause both esthetic and pathologic problems. Early detection of such teeth is most important if complications are to be avoided. In this reported case, the orthopantamogram of a 9-year-old boy revealed two impacted supernumerary teeth in the maxillary anterior region, which was interfering with the eruption of the permanent central incisors. The impacted supernumerary teeth were surgically removed, 11 was repositioned in the arch as it was situated very high in the arch, close to the nasal floor. Twenty-one erupted spontaneously but orthodontic force was applied over 11 to bring it into the occlusion and alignment was achieved with 0.014 mm NiTi wire.

Corticotomy and dental distraction have been proposed as effective and safe methods to shorten orthodontic treatment duration in adolescent and adult patients. A systematic review was performed to evaluate the evidence supporting these claims. PubMed, Embase, and Cochrane databases were searched until April 2013 for randomized controlled trials, controlled clinical trials, and case series with 5 or more subjects that focused on velocity of tooth movement, reduction of treatment duration, or complications with various surgical protocols. There were no language restrictions during the search phase. Publications were systematically assessed for eligibility, and 2 observers graded the methodologic quality of the included studies with a predefined scoring system. Eighteen articles met the inclusion criteria. Seven studies were clinical trials, with small investigated groups. Only studies of moderate and low values of evidence were found. Surgically facilitated treatment was indicated for various clinical problems. All publications reported temporarily accelerated tooth movement after surgery. No deleterious effects on the periodontium, no vitality loss, and no severe root resorption were found in any studies. However, the level of evidence to support these findings is limited owing to shortcomings in research methodologies and small treated groups. No research concerning long-term stability could be included. Evidence based on the currently available studies of low-to-moderate quality showed that surgically facilitated orthodontics seems to be safe for the oral tissues and is characterized by a temporary phase of accelerated tooth movement. This can effectively shorten the duration of orthodontic treatment. However, to date, no prospective studies have compared overall treatment time and treatment outcome with those of a control group. Well-conducted, prospective research is still needed to draw valid conclusions. Copyright © 2014 American Association of Orthodontists

In this report we describe a combined orthodontic and surgical treatment for a 14-year-old boy with severe skeletal class III deformity and dental problem. His upper posterior primary teeth in the left side were over-retained and 6 maxillary teeth (bilateral central incisors and canines, left first and second premolars) were impacted, together with 5 supernumerary teeth in both arches. The treatment protocol involved extraction of all the supernumerary and deciduous teeth, surgical exposure and orthodontic traction of the impacted teeth, a bimaxillary orthognathic approach including Lefort I osteotomy. Bilateral sagittal split ramus osteotomy (BSSRO) and genioplasty was performed to correct skeletal problem. After treatment, all of the impacted teeth were brought to proper alignment in the maxillary arch. A satisfied profile and good posterior occlusion was achieved. Treatment mechanics and consideration during different stages are discussed.

Full Text Available The aim of the present case report is to describe the orthodontic-surgical treatment of a 17-year-and-9-month-old female patient with a Class III malocclusion, poor facial esthetics, and mandibular and chin protrusion. She had significant anteroposterior and transverse discrepancies, a concave profile, and strained lip closure. Intraorally, she had a negative overjet of 5 mm and an overbite of 5 mm. The treatment objectives were to correct the malocclusion, and facial esthetic and also return the correct function. The surgical procedures included a Le Fort I osteotomy for expansion, advancement, impaction, and rotation of the maxilla to correct the occlusal plane inclination. There was 2 mm of impaction of the anterior portion of the maxilla and 5 mm of extrusion in the posterior region. A bilateral sagittal split osteotomy was performed in order to allow counterclockwise rotation of the mandible and anterior projection of the chin, accompanying the maxillary occlusal plane. Rigid internal fixation was used without any intermaxillary fixation. It was concluded that these procedures were very effective in producing a pleasing facial esthetic result, showing stability 7 years posttreatment.

This paper reviews the incidence, etiology and location of supernumerary teeth with emphasis on premolar supernumeraries and examines the management of supernumerary premolars of three patients undergoing orthodontics. These cases demonstrate that the management of premolars is assessed individually and treatments based on potential complications, which may occur during the orthodontic and surgical management of the dentition. Progress and posttreatment radiographs are recommended for the assessment of late forming supernumerary teeth.
Full Text Available Canine impaction is a dental problem very often encountered in orthodontic practice. After the third molar, the canine is the most frequently impacted tooth. Bringing the impacted canine into a normal position is important for functional occlusion and the final esthetics of the orthodontic treatment. This article illustrates a peculiar case, in which all four permanent canines maintained their unerupted status at age of 16 years. All four impacted canines were surgically exposed, attachment bonded, traction given with K-9 spring and ideally positioned with fixed orthodontic mechanotherapy.

To evaluate the treatment time and the anterior and posterior teeth movement pattern as closing extraction space for the Class III surgical patients facilitated by accelerated osteogenic orthodontic treatment. There were 10 skeletal Class III patients in accelerated osteogenic orthodontic group (AOO) and 10 patients in control group. Upper first premolars were extracted in all patients. After leveling and alignment (T2), corticotomy was performed in the area of maxillary anterior teeth to accelerate space closing.Study models of upper dentition were taken before orthodontic treatment (T1) and after space closing (T3). All the casts were laser scanned, and the distances of the movement of incisors and molars were digitally measured. The distances of tooth movement in two groups were recorded and analyzed. The alignment time between two groups was not statistically significant. The treatment time in AOO group from T2 to T3 was less than that in the control group (less than 9.1 ± 4.1 months). The treatment time in AOO group from T1 to T3 was less than that in the control group (less than 6.3 ± 4.8 months), and the differences were significant (P 0.05). Accelerated osteogenic orthodontic treatment could accelerate space closing in Class III surgical patients and shorten preoperative orthodontic time. There were no influence on the movement pattern of anterior and posterior teeth during pre-surgical orthodontic treatment.

Demineralization of a thin layer of bone over a root prominence after corticotomy surgery can optimize the response to applied orthodontic forces. This physiologic response is consistent with the regional acceleratory phenomenon process. When combined with alveolar augmentation, one is no longer strictly at the mercy of the original alveolar volume and osseous dehiscences, and fenestrations can be corrected over vital root surfaces. This is substantiated with computerized tomographic and histologic evaluations. Two case reports are presented that demonstrate the usefulness of the accelerated osteogenic orthodontics technique in de-crowding and space closing for the correction of dental malocclusions. Orthodontics is combined with full-thickness flap reflection, selective alveolar decortication, ostectomy, and bone grafting to accomplish complete orthodontic treatment. Rapid tooth movement was demonstrated in both cases and stability up to 8 years of retention. The accelerated osteogenic orthodontics technique provides for efficient and stable orthodontic tooth movement. Frequently, the teeth can be moved further in one third to one fourth the time required for traditional orthodontics alone. This is a physiologically based treatment consistent with a regional acceleratory phenomenon and maintaining an adequate blood supply is essential.
Full Text Available A 13-year-old female patient reported with the chief complaint of irregular front teeth. She had a skeletal Class III and Angle′s Class I malocclusion with hyperdivergent growth pattern and bilateral impaction of maxillary canines. Surgical exposure of the impacted teeth and orthodontic alignment was planned. The surgical exposure was done by a minimally invasive modified window technique. Orthodontic treatment of impacted canines without causing significant morbidity to the adjacent teeth and periodontium is a challenge. The bilaterally impacted maxillary canines were successfully aligned and leveled. The depth of the gingival sulcus and clinical crown heights of disimpacted teeth were normal post-treatment and after 1 year of retention.

This case report describes the treatment of a patient with a horizontally impacted maxillary central incisor, a canine in the same quadrant, and an inclusion tendency. Due to severe crowing in the maxilla and the Class II molar relationship on the impaction side, a 2-stage treatment plan was developed. In the first stage, the right first premolar and deciduous canine were extracted; this allowed enough space for the eruption of the maxillary right permanent canine. The second stage included surgical exposure and traction of the impacted central incisor with a fixed orthodontic appliance. An excisional uncovering technique was needed to expose the impacted incisor. After it erupted, an apically positioned partial-thickness flap was used to add keratinized attached gingiva in the area surrounding the crown, initially located in an area of unattached gingiva. The patient finished treatment with a normal and stable occlusion between the maxillary and mandibular arches and an adequate width of attached gingiva.

This case report reiterates the fact that selective alveolar decortication in conjunction with periodontal alveolar augmentation with a bone graft indubitably and efficaciously produces rapid orthodontic tooth movement. A 29-year-old woman presented with a Class I malocclusion and increased bidentoalveolar protrusion with increased spacing between the maxillary and mandibular incisors. She readily agreed to selective alveolar decortication in conjunction with periodontal alveolar augmentation with a bone graft when presented with the proposal that her malocclusion could be corrected in one-third the treatment time required for conventional orthodontics. A preadjusted edgewise appliance (Roth prescription, 0.022 x 0.028-inch slot) was placed prior to the surgical procedure. One week later, full-thickness labial and lingual flaps were reflected in the maxillary and mandibular arches. The alveolar bone was selectively decorticated and periodontally augmented with a bone graft. Starting 1 week postsurgically, orthodontic adjustments were carried out every 2 weeks. From bracketing to debracketing, the entire orthodontic treatment took 7 months. The rapid orthodontic tooth movement was attributed to the regional acceleratory phenomenon, triggered by selective alveolar decortication. The subsequent periodontal alveolar augmentation with the bone graft repaired the bony dehiscences and enhanced the bone volume and dramatically improved the patient's soft tissue profile.

The lingual technique was introduced in the late '70s and, just like orthodontics, it has developed significantly in the past few years. Adult and young adult have been attracted to such alternative aesthetic treatment. Despite their need of orthodontic treatment, they want to have an aesthetic alternative, as "invisible" as possible--something that can be achieved with the lingual technique. Nevertheless, many treatment or re-treatment cases also demand correction through orthognathic surgery, a process which is nowadays much simpler and considered an effective auxiliary method for the malocclusion correction. Having posed that, this study aims to show correction of malocclusion and discrepancy between dental arches through lingual orthodontic technique associated to orthognathic surgery. This study shows that it is possible to provide the patient who suffers frJom malocclusion with proper correction, achieving the desired aesthetics by using lingual braces and pe?forming lingual orthognathic surgery.

Introduction. "Dens invaginatus" is a dental anomaly which originates from the invagination of the ameloblastic epithelium into the lingual surface of the dental crown during the odontogenesis. It can cause early pulpal necrosis, abscesses, retention or dislocation of contiguous elements, cysts, and internal resorptions. It normally affects the upper lateral incisors. In the following study the authors will discuss the etiology, the physiopathology, and the surgical-orthodontic management of a rare case of impacted canine associated with dens invaginatus and follicular cyst, with the aim of highlighting the importance of taking any therapeutic decision based on the data available in the literature. Case Report. The present study describes a combined surgical-orthodontic treatment of an impacted canine associated with a lateral incisor (2.2) suffering from type III dens invaginatus with radicular cyst, in a 15-year-old patient. Discussion. When treating a dens invaginatus there are different therapeutic solutions: they depend on the gravity of the anomaly and on the association with the retention of a permanent tooth. The aesthetic and functional restoration becomes extremely important when performing a surgical-orthodontic repositioning.

Our aims were to assess the perceptions of orthodontic case complexity among orthodontists, general dentists, orthodontic residents, and dental students and to compare their perceptions with the American Board of Orthodontics Discrepancy Index (DI). Orthodontists, general dentists, orthodontic residents, and dental students (n = 343) participated in a Web-based survey. Pretreatment orthodontic records of 29 cases with varying DI scores were obtained. Respondents were asked to evaluate case complexity on a 100-point visual analog scale. Additional information was collected on participants' orthodontic education and orthodontic treatment preferences. Pearson correlation coefficients were used to assess the relationship between the average complexity score and the DI score. Repeated measures analysis with linear mixed models was used to assess the association between the average complexity score and the DI score and whether the association between the 2 scores varied by level of difficulty or panel group. The level of significance for all analyses was set at P clear aligners. DI score was significantly associated with complexity perceptions (P = 0.0168). Associations between average complexity and DI score varied significantly by provider group (P = 0.0033), with orthodontists and residents showing the strongest associations. When the DI score was greater than 15, orthodontists and residents perceived cases as more complex than did the other provider groups. Orthodontists and orthodontic residents had better judgments for evaluating orthodontic case complexity. The high correlation between orthodontic professionals' perceptions and DI scores suggested that additional orthodontic education and training have an influence on the ability to recognize case complexity.

Full Text Available Various anomalies in the size, shape, number, structure and eruption of the teeth are often observed clinical conditions. Supernumerary teeth can be found in almost any region of the dental arch, and most of the times they are asymptomatic, and are routinely found during radiographic evaluation. The most common cause of impacted maxillary incisors is the presence of the supernumerary teeth. This paper describes a case of multiple supernumerary teeth associated with an impacted permanent maxillary central incisor in an 11-year old child along with its surgical and orthodontic management.

Fusion is one of the developmental dental anomalies in which two adjacent teeth are joined at the crown level forming a single tooth with an enlarged crown. Fusion causes some clinical problems such as unaesthetic appearance, pain, caries, and malocclusion. The management of fusion often needs multidisciplinary approach to give best possible esthetic and functional outcome. This paper reports a case of 9-year-old boy with fused maxillary left central and lateral incisors who was treated with 2 × 4 fixed orthodontic appliances after surgical separation of fused teeth.

To conduct a systematic review of randomised controlled trials (RCTs) evaluating the effect of surgical and non-surgical procedures on the acceleration of orthodontic tooth movement (OTM) as an adjunct to orthodontic therapy (OT) in order to estimate the efficacy of these procedures and the benefit of their use in everyday orthodontic practice. Literature search was performed on PubMed, Scopus, Web of Science and Cochrane databases up to July 2014. Inclusion criteria were: (1) RCTs; (2) orthodontic therapy on permanent dentition; (3) application of adjunctive surgical or non-surgical procedures for accelerating OTM; (4) measurement of tooth movement. The primary outcome measure was tooth movement expressed as cumulative tooth movement (CTM), rate of tooth movement (RTM) or time of tooth movement (TTM). Pain and discomfort, periodontal health, anchorage loss, bone and root changes, and undesired tooth movement were evaluated as secondary outcomes. Literature research identified 184 studies. After screening of titles, abstracts and full-text studies, fifteen fulfilled the inclusion criteria and were included in this review. Six of the included studies investigated the effect of corticotomies, one of interseptal bone reduction, four of lowlevel laser therapy (LLLT), three of intraoral/extraoral devices releasing extracorporeal shock waves (ESWT), pulsed electromagnetic field (PEMF) and electrical current, respectively, and one of injected substances (relaxin) as an adjunct to OT. Three studies resulted of high methodological quality, six of medium, and six of low quality. Interseptal bone reduction was reported to increase RTM during the first 2 months (P = 0.002) and CTM at 3 months (P = 0.003). Studies investigating corticotomy reported significantly increased RTM (up to 2.3 times) during the first months after intervention, whereas results on TTM and CTM were quite controversial ranging from non-significant to highly significant (up to three times of TTM increase
Full Text Available Aim: The aim of this study was to compare the periodontal status of impacted canines after 5 years following completion of the combined surgical and orthodontic treatment. Materials and methods: We examined 20 labially impacted canines and 20 palatally impacted canines at 5 years after the end of treatment. We assessed the periodontal status of these teeth. Results: Different outcomes were found regarding the probing depth and the amount of keratinized gingiva in the two mentioned groups of teeth. Conclusions: The assessed periodontal indices may signal the appearance of a periodontal disease around the teeth that were surgically and orthodontically treated
Full Text Available Contact dermatitis is an inflammatory reaction of the skin and mucosa to either external or internal factors. It can be divided to two forms of irritant contact dermatitis and allergic contact dermatitis. Nickel is one of the most common materials that causes allergic contact dermatitis and is widely used in orthodontic appliances. The inflammatory reaction to this metal in orthodontics is usually stomatitis and angular cheilitis is very rare.

Interdisciplinary treatment planning is an essential part of orthodontic therapy for patients with partial edentulism, especially when dental implants are to serve initially as anchorage and ultimately as prosthetic abutments for the definitive fixed restoration. A technique is presented for designing and fabricating a computed tomography-based surgical guide to place definitive implants before orthodontic therapy. First, the diagnostic cast and the orthodontic tooth arrangement and diagnostic waxing cast are scanned with a 3-dimensional optical scanner. Three-dimensional renderings of these scans are then merged and superimposed onto the cone beam computed tomography (CBCT) image with implant planning software to develop definitive implant positions. A custom surgical guide is fabricated from these data. Copyright © 2015 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc. All rights reserved.

To evaluate if the improved accelerated osteogenic orthodontics (IAOO) procedure could speed Class III surgical patients' preoperative orthodontic treatment duration and, if yes, to what extent. This study was also designed to determine whether or not an IAOO procedure affects the tooth-moving pattern during extraction space closure. The samples in this study consisted of 24 Class III surgical patients. Twelve skeletal Class III surgery patients served as an experimental group (group 1) and the others as a control group (group 2). Before treatment, the maxillary first premolars were removed. For group 1, after the maxillary dental arch was aligned and leveled (T2), IAOO procedures were performed in the maxillary alveolar bone. Except for this IAOO procedure in group 1, all 24 patients experienced similar combined orthodontic and orthognathic treatment. Study casts of the maxillary dentitions were made before orthodontic treatment (T1) and after extraction space closure (T3). All of the casts were laser scanned, and the amount of movement of the maxillary central incisor, canine, and first molar, as well as arch widths, were digitally measured and analyzed by using the three-dimensional model superimposition method. The time durations T3-T2 were significantly reduced in group 1 by 8.65 ± 2.67 months and for T3-T1 were reduced by 6.39 ± 2.00 months (P teeth movement in the sagittal, vertical, and transverse dimensions between the two groups (P > .05). The IAOO can reduce the surgical orthodontic treatment time for the skeletal Class III surgical patient by more than half a year on average. The IAOO procedures do not save anchorage.

One of the prime concerns of both the orthodontist and the oral surgeon must be the final soft tissue profile and the esthetic appearance of the patient. The purpose of this study was to evaluate the amount, direction, and predictability of the soft tissue changes associated with simultaneous skeletal changes. The authors analyzed the recent 22 cases with skeletal class II maloclusion in Orthodontic Department, College of Stomatology, West China University of Medical Sciences with 7 male and 15 female from 20 to 30 years old. Each patient was taken standardized lateral cephalograms before the treatment and 6-12 months after the treatment. A total of 16 hard and soft tissue landmarks were evaluated in both horizontal and vertical directions. In the horizontal directions, the soft tissue maxillary landmarks (superior labial sulcus, labrale superius, and upper lip stomion) moved posterior with a range of 2.17 to 2.33 mm. The strongest correlations were found between the posterior movement of the upper incisal edge and the three soft tissue parameters: superior labial sulcus r = 0.78, labrale superius r = 0.81, upper lip stomion r = 0.75. The soft/hard tissue ratios of the mandible anterior movement is 0.83:1 between inferior labial sulcus and B point, and 0.95:1 for Pog' to Pog. In the vertical directions, all the soft tissue mandible landmarks (Pog', inferior labial sulcus, labrale inferius, lower lip stomion) moved upward more than 2 mm. And the soft/hard tissue ratio is from 1.07:1 to 1.34:1. The combined orthodontic and surgical treatment is an efficient way to cure skeletal class II malocclusion. All the patients regained satisfactory face appearance and profile. Although the soft tissue movement is less than the hard tissue in both jaws in the horizontal direction, the vertical movement of the mandibular soft tissue is greater than that of the underlying hard tissue.

Full Text Available Mandibular incisor extraction for orthodontic treatment is considered an unusual treatment option because of the limited number of patients that meet the criteria for such treatment. Accurate diagnosis and treatment planning is essential to achieve the desired results. Adult orthodontic patients are increasingly motivated by esthetic considerations and reject the idea of conventional fixed appliances. In recent years, Invisalign appliances have gained tremendous attention for orthodontic treatment of adult patients to meet their esthetic demands. In this case report, a case of Class I malocclusion was treated with mandibular incisor extraction using the Invisalign appliance system. Successful tooth alignment of both arches was achieved. The use of Invisalign appliance is an effective treatment option in adult patients with Class I malocclusion that requires incisor extraction due to moderate to severe mandibular anterior crowding.

An anterior open bite is a challenge to orthodontic treatment; it has a multifactorial etiology and a wide range of intervention options. Temporomandibular joint (TMJ) disorders are a risk factor for the development of malocclusions such as the anterior open bite, especially in patients who have TMJ osteoarthritis with disc displacement. Articular disc repositioning surgery is an available option for treating this pathology, and it contributes to maintaining the condyles in a more stable position. The aim of this article was to report the case of a 20-year-old woman diagnosed with anterior open bite and TMJ osteoarthritis with bilateral disc displacement. The patient received both orthodontic treatment and TMJ disc repositioning surgery. Cone-beam computed tomography was used to create 3-dimensional models of the condyles with regional superposition, and assessment of bone remodeling was performed at different time intervals. Complete orthodontic and surgical treatment time was approximately 12 months. The results provided a stable correction of the patient's anterior open bite with a 2-year follow-up and favorable bone remodeling of the condyles due to functional improvement of the TMJ.

Full Text Available INTRODUCTION: Orthodontic-surgical treatment was performed in patient with skeletal Class III malocclusion due to exceeding mandibular growth. Patient also presented upper and lower dental protrusion, overjet of -3.0 mm, overbite of -1.0 mm, congenital absence of tooth #22, teeth #13 and supernumerary impaction, tooth #12 with conoid shape and partly erupted in supraversion, prolonged retention of tooth #53, tendency to vertical growth of the face and facial asymmetry. The discrepancy on the upper arch was -2.0 mm and -5.0 mm on the lower arch. METHODS: The pre-surgical orthodontic treatment was performed with extractions of the teeth #35 and #45. On the upper arch, teeth #53, #12 and supernumerary were extracted to accomplish the traction of the impacted canine. The spaces of the lower extractions were closed with mesialization of posterior segment. After aligning and leveling the teeth, extractions spaces closure and correct positioning of teeth on the bone bases, the correct intercuspation of the dental arch, with molars and canines in Angle's Class I, coincident midline, normal overjet and overbite and ideal torques, were evaluated through study models. The patient was submitted to orthognathic surgery and then the post-surgical orthodontic treatment was finished. RESULTS: The Class III malocclusion was treated establishing occlusal and facial normal standards.

The aim of this prospective study was to evaluate the effectiveness of an innovative, minimally invasive, flapless corticotomy procedure in orthodontics. The STROBE guidelines were followed. Ten patients with severe dental crowding and a class I molar relationship were selected to receive orthodontic treatment with clear aligners and corticotomy-facilitated orthodontics. The mean age of these patients was 21 years (range 17-28, standard deviation 6.08 years); the male to female ratio was 2:1. The main outcome was a reduction in the total treatment time to correct dental crowding. The secondary outcomes were periodontal index changes, the degree of root resorption, and patient perceptions of the method used, assessed using the short-form Oral Health Impact Profile (OHIP-14). The occurrence of early surgical complications or unexpected events was also recorded. All patients completed the treatment to correct dental crowding. The average treatment time was reduced by two-thirds. The procedure did not significantly modify the periodontal indices or oral health-related quality of life. No early surgical complications or unexpected events were observed. In short, the results indicate that this new procedure is safe and accelerates tooth movement without periodontal complications or discomfort. However, the efficacy of this procedure must be confirmed in controlled clinical trials. Copyright © 2016 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

We explored the gene expression profile altered by orthodontic tooth movement (OTM) during the healing of surgical alveolar defects in beagles. An OTM-related healing model was established where a maxillary second premolar was protracted into the critical-sized defect for 6 weeks (group DT6). As controls, natural healing models without OTM were set at 2 weeks (group D2) and at 6 weeks (group D6) after surgery. Total RNAs were extracted from dissected tissue blocks containing the regenerated defects and additionally from sound alveolar bone as a baseline (group C). mRNA profiling was performed using microarray analysis. Functional annotations of gene clusters based on differentially expressed genes among groups indicated that the gene expression profile of group DT6 had a stronger similarity to that of group D2 than to group D6. The genes participating in high woven-bone fraction in group DT6 could be identified as TNFSF11, MMP13, SPP1, and DMP1, which were verified by quantitative real-time polymerase chain reactions. We investigated at the gene level that OTM can affect the healing state of surgical defects serving as favorable matrices for OTM with defect regeneration. It would be a basis on selecting putative genes to be therapeutically applied for tissue-friendly accelerated orthodontics in the future. Copyright © 2017 American Association of Orthodontists.

The aim of this study was to compare electromyographic data of two groups of patients (open and deep skeletal bite) before and after surgical orthodontic treatment. All patients who underwent orthognathic surgery at the Department of Orthodontics (University of Milan) were subjected to periodic electromyographic evaluation of the masticatory muscles (masseter and anterior temporal muscles) and to electrokinesiographic evaluation of mandibular movements. The sample comprised 72 patients (35 open skeletal bite patients and 37 deep skeletal bite patients) at the end of craniofacial growth. The electromyographic instruments used in the study included a Freely and a K6-I electromyograph. Statistical evaluation was carried out with Student's t tests for independent samples. Lots of differences between open and deep skeletal bite patients have been underlined by the analysis of the electromyographic data obtained. These results have been obtained with both electromyographic systems. Muscular activity in microvolts is higher in deep skeletal bite patients at the beginning of the treatment than in open bite ones, but during the following phases of the treatment, the two values became similar. Morphologic differences between open and deep bite patients can also be demonstrated by instrumental examinations, and their correction after surgical treatment is observable on electromyographic and electrognatographic exams.

Accelerating the rate of tooth movement may help to reduce the duration of orthodontic treatment and associated unwanted effects including root resorption and enamel demineralisation. Several methods, including surgical and non-surgical adjuncts, have been advocated to accelerate the rate of tooth movement. Non-surgical techniques include low-intensity laser irradiation, resonance vibration, pulsed electromagnetic fields, electrical currents and pharmacological approaches. To assess the effect of non-surgical adjunctive interventions on the rate of orthodontic tooth movement and the overall duration of treatment. We searched the following databases on 25 November 2014: the Cochrane Oral Health Group's Trials Register (November 2014), the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library 2014, Issue 10), MEDLINE via OVID (1946 to November 2014), EMBASE via OVID (1980 to November 2014), LILACS via BIREME (1980 to November 2014), metaRegister of Controlled Trials (November 2014), the US National Institutes of Health Trials Register (ClinicalTrials.gov; November 2014) and the WHO International Clinical Trials Registry Platform (November 2014). We checked the reference lists of all trials identified for further studies. There were no restrictions regarding language or date of publication in the searches of the electronic databases. We included randomised controlled trials (RCTs) of people receiving orthodontic treatment using fixed appliances along with non-surgical adjunctive interventions to accelerate tooth movement. We excluded non-parallel design studies (for example, split-mouth) as we regarded them as inappropriate for assessment of the effects of this type of intervention. Two review authors were responsible for study selection, risk of bias assessment and data extraction; they carried out these tasks independently. Any disagreements were resolved by discussion amongst the review team to reach consensus. The review authors contacted

Patients who have malocclusions caused by bone diseases come to see the dentist for the orthodontic treatment. One of these diseases is fibrous dysplasia. The aim of this study was to present the patient with the active form of fibrous dysplasia who reported to the Orthodontic Department of Pomeranian Medical University in Szczecin for treatment. We used the patient's own documentation, photos, radiological view and histopathological investigations. The extraoral, clinical examination revealed the asymmetry of the face on the left side, while the intraoral examination showed the convex lesion similar to an egg on the palate which crosses the medial line and clear "distension" of the alveolar bone in the direction of the oral vestibule. The dysplastic lesions are extensive and cause numerous malocclusions and disorders of the symmetry. The radiological and histopathological examinations were added to the clinical examination. The panoramic radiographs have shown the asymmetry and heterogenic structure of the bone with areas of"ground glass". Computer tomography demonstrated bumpy thickening of the zygomatic bone, maxilla, and a great wing of the sphenoid bone and almost completely filled maxillary sinus. The histopathological examination is the confirmation of the diagnosis of fibrous dysplasia. It demonstrates immature bone. The diagnosis of fibrous dysplasia commands the periodic observation and the postponement of the orthodontic treatment in the stage of active development of lesions, but when the overgrowth impairs the function, there is the necessity to use surgical and radical excision to remove lesions. We must pay particular attention to the possibility of malignant transformation of these lesions.

This case report describes a 13-year-old boy with alveolar bony defect resulted from surgical removal of impacted upper canine transposed in the anterior region. The boy had a normal occlusion with malposition of upper central and lateral incisors. The treatment objectives were to align teeth, close spaces by mesial movement of the buccal segments in the upper jaw to repair bone loss. Fixed appliance with palatal root torque was used for the mesial movements, levelling, and alignment of teeth.Orthodontic tooth movement consisted of a sequence of root movement in a direction to increase the thickness of the labial cortical plate of bone, could ensure healthier periodontium. A healthier periodontium prior to space closure ensured repair of alveolar bony defect after surgical intervention. Orthodontic tooth movement should be added to our armamentarium for the repair of alveolar bony defect.

Invasive cervical resorption (ICR), a destructive form of external root resorption, is characterized by invasion of the fibrovascular tissue. This phenomenon is very rare and appears in 0.02% of the general population where the leading factors are orthodontics in addition to trauma, restorations, and bleaching. Heavy orthodontic force may increase the incidence to 1%. One of the main concerns regarding ICR is that it is often misdiagnosed with conventional diagnostic tools. In recent decades, a cone beam computed tomography (CBCT) imaging technique has become more common and can lead to a more accurate diagnosis and treatment plan. This case report describes a possible association between orthodontic treatment and ICR of a 14-year-old male, 18 months post orthodontic treatment. ICR in the mandibular right canine was diagnosed and verified by CBCT, and underwent combined endodontic-periodontal treatment. However, after orthodontic forced eruption was performed on this tooth to improve the bone defect, ICR was diagnosed on the mandibular right second premolar. The possible association between orthodontic treatment and ICR is discussed, as ICR was noted following orthodontic treatment on both occasions. This case report stresses the importance of ICR early detection by close attention to periodic radiographic checkups during orthodontic treatment. The use of modern diagnostic tools is highly recommended in suspicious cases. A case is described in which the patient underwent two types of orthodontic treatment in the mandible at different time periods and developed ICR in two different teeth.

This case report describes the healing of gingival recessions on mandibular incisors resulting from orthodontic treatment of a deep bite malocclusion at a 30-year follow-up observation. The marked improvement in the severe recessions was a consequence of the elimination of the direct trauma, orthodontic intrusion of the affected teeth, and subsequent creeping attachment over time. No periodontal treatment was performed before or after orthodontic treatment.

Pubmed, Embase, Google scholar beta and the Cochrane Databases. Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) reporting on results or treatment parameters related to accelerated orthodontic tooth movement were considered. Data abstraction and quality assessment using the Cochrane risk of bias tool were carried out independently by two reviewers. A meta-analysis and narrative synthesis was presented. Eighteen studies (342 patients ) were included. Eight involved low intensity laser, seven corticotomy, and interseptal bone reduction, pulsed electromagnetic fields and photobiomodulation were each investigated by a single trial. Twelve RCTs and six CCTs were included. Two RCTs were considered to be at low risk of bias, five at unclear risk and five at high risk of bias. Three CCTS were at high risk of bias and three at unclear risk. Two studies on corticotomy and two on low intensity laser were combined in a random effects model. Higher canine retraction rate was evident with corticotomy during the first month of therapy (WMD=0.73; 95% CI: 0.28, 1.19, ppulsed electromagnetic fields. Overall, the results should be interpreted with caution given the small number of studies, allied to limited quality and heterogeneity of the included studies. Further research is required in this field with additional attention to application protocols, adverse effects and cost-benefit analysis.

Introduction Conventional treatments are sometimes not possible in certain alveolar cleft cases due to the severity of the gap which separates the fragments. Various management strategies have been proposed, including sequential surgical interventions or delaying treatment until adulthood to then carry out maxillary osteotomies. A further alternative approach has also been proposed, involving the application of bone transport techniques to mobilise the osseous fragments and thereby reduce the gap between lateral fragments and the premaxilla. Case Report We introduce the case of a 10-year-old patient who presented with a bilateral alveolar cleft and a severe gap. Stable occlusion between the premaxilla and the mandible was achieved following orthodontic treatment, making it inadvisable to perform a retrusive osteotomy of the premaxilla in order to close the alveolar clefts. Faced with this situation, it was decided we would employ a bone transport technique under orthodontic guidance using a dental splint. This would enable an osseous disc to be displaced towards the medial area and reduce the interfragmentary distance. During a second surgical intervention, closure of the soft tissues was performed and the gap was filled in using autogenous bone. Conclusions The use of bone transport techniques in selected cases allows closure of the osseous defect, whilst also preserving soft tissues and reducing the amount of bone autograft required. In our case, we were able to respect the position of the premaxilla and, at the same time, generate new tissues at both an alveolar bone and soft tissue level with results which have remained stable over the course of time. Key words:Alveolar cleft, bone transport, graft. PMID:26855699
Full Text Available Background: Traditionally, maxillofacial deformities are corrected surgically after an initial orthodontic treatment phase. However in, this article, the authors emphasize the postsurgical therapeutic protocol which is extremely important for determining the final and permanent retention of the corrected occlusion.Methods: A 55 year old female with severe skeletal Class II malocclusion is presented. Combined surgical and orthodontic correction of the malocclusion was used.Results: The step-by-step procedure the authors followed for the postsurgical therapy is described. The goals of the postoperative therapy were to restore and rehabilitate neuromuscular function, obtain occlusal stabilization, grind teeth selectively, and final occlusion retention. The importance of a surgical occlusal splint for rehabilitating stomatognathic neuromuscular function postoperatively was demonstrated. Furthermore, the orthodontic-prosthodontic treatment ensured occlusion stability after the surgical correction. The long-term results confirmed the efficacy of the treatment protocol presented here from both functional and aesthetical perspectives.Conclusions: Postsurgical orthodontic treatment is an important step in the surgical and orthodontic therapy of maxillofacial deformities.

Extensive intraosseous lesions represent a clinical challenge for the periodontist. Sites with bone defects have been shown to be at higher risk of periodontitis progression in patients who had not received periodontal therapy. Thus, the aim of this case report was to describe a novel approach for the treatment of 1-walled intraosseous defect by combining nonsurgical periodontal therapy and orthodontic movement toward the bone defect, avoiding regenerative and surgical procedures. A 47-year-old woman underwent the proposed procedures for the treatment of her left central incisor with 9 mm probing depth and 1-walled intraosseous defect in its mesial aspect. Initially, basic periodontal therapy with scaling and root planning was accomplished. Two months later, an orthodontic treatment was planned to eliminate the intraosseous lesion and to improve the interproximal papillary area. Orthodontic root movement toward the osseous defect was performed for 13 months with light forces. After 6 years postoperative it was concluded that combined basic periodontal therapy and orthodontic movement was capable of eliminating the intraosseous defect and improve the esthetics in the interproximal papillary area between the central incisors.

The use of orthodontic treatment in adult patients is becoming more common and these patients have more specific objectives and concerns related to facial and dental aesthetics, specially regarding duration of treatment. Dentists are on the lookout for techniques for increased efficiency in orthodontic treatment. Alveolar Corticotomy-assisted orthodontic treatment is a recent orthodontic technique that is recently gaining wide acceptance and is recorded as effective means of accelerating orthodontic treatment. A 17-year-old female patient was undergoing orthodontic treatment for the past one year but during her space closure, a visual examination confirmed a buccal thickening that was encountered in the buccal plate between premolars and canine. Periodontal intervention involved elective alveolar decortication in the form of dots performed around the teeth that were to be moved. This was carried out to induce a state of increased tissue turnover and a transient osteopenia, which further helps in faster rate of orthodontic tooth movement. Its main advantages are reduction of treatment time and post-orthodontic stability. PMID:26894189

In adult interdisciplinary treatments with using dental implants, limited orthodontic treatment, especially orthodontic extrusion (OE), offers many benefits by both correcting teeth alignment and by contributing to the regeneration of periodontal tissues. However, orthodontic procedures carry some risks and unpredictabilities that might compromise tooth and/or periodontal tissue health. Especially in complex cases, it is difficult to decide which orthodontic treatment modalities should be combined, in what sequences they should be applied, and what their force systems and treatment times are.To achieve optimum results, some cases require two or more OEs to the same site being carried out at different times while taking the treatment effects into consideration. Such staged OE offers minimum intervention and maximum efficiency. In this case report, OE was first applied for orthodontic extraction. After bone regeneration followed by an implant placement and another surgical operation, a second OE was applied to align the inclination of an adjacent tooth. As a result, a predictable prognosis of implants as well as greatly improved esthetics and periodontal tissue health were achieved.

The approach to skeletal dysmorphisms in the maxillofacial area usually requires an orthodontic treatment by means of fixed appliances, both before and after the surgical phase. Since its introduction, Invisalign system has become a popular treatment choice for the clinicians because of the aesthetics and comfort of the removable clear aligners compared with the traditional appliances. Therefore, the aim of the present report was to illustrate the management of a malocclusion by means of Invisalign system associated with the traditional surgical technique. The present paper shows a case of a 23-year-old male patient characterized by a Class III malocclusion with lateral deviation of the mandible to the left side and cross-bite on teeth 2.2, 2.3, and 2.4. Invisalign system was used during the pre- and postsurgical phases rather than fixed appliances. The posttreatment cephalometric analysis emphasized the stability of the dental and skeletal symmetry corrections, occlusion and functional balance, over a 6-year follow-up. The results achieved at the end of the treatment showed how Invisalign can be effective in the management of the orthodontic phases in orthognathic surgery. The follow-up after 6 years emphasizes the stability of the treatment over time.

This article describes the treatment of a patient with periodontally "hopeless" teeth by conservative periodontal therapy combined with subgingival chlorhexidine irrigation and orthodontic tooth movement. The 3-year follow-up post-treatment shows the relative success of the treatment, without the use of surgical modality or the extraction of any teeth.
Background A reduction in orthodontic treatment time can be attained using corticotomies. The aggressive nature of corticotomy due to the elevation of muco-periosteal flaps and to the duration of the surgery raised reluctance for its employ among patients and dental community. This study aims to provide detailed information on the design and manufacture of a 3D-printed CAD-CAM (computer-aided design and computer-aided manufacturing) surgical guide which can aid the clinician in achieving a minimally-invasive, flapless corticotomy. Material and Methods An impression of dental arches was created; the models were digitally-acquired using a 3D scanner and saved as STereoLithography ( STL ) files. The patient underwent cone beam computed tomography (CBCT): images of jaws and teeth were transformed into 3D models and saved as an STL file. An acrylic template with the design of a surgical guide was manufactured and scanned. The STLs of jaws, scanned casts, and acrylic templates were matched. 3D modeling software allowed the view of the 3D models from different perspectives and planes with perfect rendering. The 3D model of the acrylic template was transformed into a surgical guide with slots designed to guide, at first, a scalpel blade and then a piezoelectric cutting insert. The 3D STL model of the surgical guide was printed. Results This procedure allowed the manufacturing of a 3D-printed CAD/CAM surgical guide, which overcomes the disadvantages of the corticotomy, removing the need for flap elevation. No discomfort, early surgical complications or unexpected events were observed. Conclusions The effectiveness of this minimally-invasive surgical technique can offer the clinician a valid alternative to other methods currently in use.

Full Text Available Aim. Orthodontic elastic bands were proposed as being the source of gingival abscesses that can rapidly lead to bone loss and teeth exfoliation. We report an adolescent, otherwise, healthy patient whose periodontal status was sound. Shortly after undergoing preparations for orthodontic treatment consisting of orthodontic separators, he presented with a periodontal abscess for which there was no apparent etiology. A non-orthoradial X-ray was inconclusive, but an appropriate one revealed a subgingival orthodontic separator as the cause of the abscess. Removal of the separator and thorough scaling led to complete resolution of the abscess, but there was already residual mild damage to the alveolar bone. Summary. Failure to use appropriate imaging to reveal the cause of gingival abscesses can result in the delay of implementing treatment and halting irreversible alveolar bone loss. An inflammatory process restricted to the gingiva and refractive to conventional therapy should raise the possibility of a foreign body etiology.
Full Text Available Multiple idiopathic external root resorption is a rare pathological condition usually detected as an incidental radiographic finding. External root resorption of permanent teeth is a multifactorial process related to several local and systemic factors. If an etiological factor cannot be identified for root resorption, the term "idiopathic" is applied. This report presents a case of multiple idiopathic apical root resorption. The condition was found in a young female patient seeking orthodontic treatment due to malocclusion. This kind of resorption starts apically and progresses coronally, causing a gradual shortening and rounding of the remaining root. Patients with this condition are not the ideal candidates for orthodontic treatment; however, the aim of this report is to describe an unusual case of idiopathic root resorption involving the entire dentition, and to present the orthodontic treatment of this patient. It describes the progress and completion of orthodontic therapy with satisfactory end results.

One of the most common oral surgical procedures is the extraction of the lower third molar (LTM). Postoperative complications such as paresthesia due to inferior alveolar nerve (IAN) injury are commonly observed in cases of horizontal and vertical impaction. The present report discusses a case of a vertically impacted LTM associated with a dentigerous cyst. An intimate contact between the LTM roots and the mandibular canal was observed on a panoramic radiograph and confirmed with cone-beam computed tomographic (CBCT) cross-sectional cuts. An orthodontic miniscrew was then used to extrude the LTM prior to its surgical removal in order to avoid the risk of inferior alveolar nerve injury. CBCT imaging follow-up confirmed the success of the LTM orthodontic extrusion.

The aim of the study was to collect information about the oral health-related quality of life (OHRQoL) after combined orthodontic and maxillofacial surgical treatment as well as its influence on health-related quality of life (HRQoL). The study includes data from a total of 130 subjects, 65 of whom (21 male, 44 female, mean age at baseline: 24 years, mean age at the time of surgery: 26 years) were compared with control subjects matched on the basis of gender and age. The set of questionnaires used consisted of a questionnaire advanced by the authors including 35 general and treatment-specific questions, and the German version of the validated "Orthognathic Quality of Life Questionnaire" (OQLQ) to analyze the specific OHRQoL, and the SF-36 to measure HRQoL. The main reason for treatment was most often a combination of esthetic and functional complaints. In most cases, the treatment results met the expectations of subjects well or very well, particularly in the areas of aesthetics and masticatory function. Postoperative numbness or paresthesia were present in 59% of patients, especially in the chin and lower lip areas. In all, 20% of subjects considered the temporary restriction of mouth opening as very bothersome. A decrease in HRQoL was noted as compared with the control group in the subscales of "role physical" (p oral function" (p maxillofacial surgical treatment. However, even after combined orthodontic and maxillofacial surgical treatment of malocclusion patients, it is possible to detect smaller limitations with regard to the specific OHRQoL, which may have a negative impact on HRQoL. Based on the results, a participatory decision-making process focusing on the individual therapy-related expectations, desires, and psychological factors of the patient concerning the improvements effected by the treatment appears to be advisable.

The lingual orthodontic therapy though started in 1972, could not be popular till the beginning of 1990. In Nepal it does not have a history of more than a year. It is started in Dhulikhel Hospital for the first time in Nepal. Usually orthodontic therapy is meant for putting braces on the labial surface of the teeth which is called labial orthodontic system. Lingual orthodontic system is a purely invisible kind of orthodontic therapy in which braces are placed behind the teeth. The advantages of lingual orthodontic therapy are: invisibility, better biomechanics and improved patient compliance. On the other hand it is difficult to master and costlier than labial orthodontics. We have presented six adjunctive orthodontic cases treated by lingual system with the same end result comparable to labial orthodontic system.

Full Text Available Orthodontic treatments involving missing or compromised first permanent molars are often challenging cases to treat considering the loss of potential anchor tooth. The case series presents orthodontic treatment in three patients with mutilated/absent first permanent molars. The treatment goals were to be accomplished by extraction of compromised teeth and retention of healthy dentition. The diagnosis and problem list needed extractions to accomplish the treatment goals. The possibility of extracting compromised first permanent molars instead of other healthy teeth was considered. A setup was done to determine the final occlusion in asymmetric extraction cases. Fixed appliances were used with simple mechanics without any additional anchorage devices. Case-based retention protocols were followed. All the three patients achieved the predetermined treatment objectives of improved esthetics and healthy and stable functional occlusion. The simple and efficient mechanics and finishing techniques for comprehensive orthodontic treatment with first molar extractions presented in the report should help clinicians when treating similar patients.

Although surgical treatment protocols for cleft lip and palate patients have been established, many patients still have some soft tissue defects after complete healing from surgical interventions. These are excess soft tissue, high attached fraena and firmed tethering scares. These soft tissue defects resulted shallowing of vestibule, restricted tooth movement, compromised periodontal health and trended to limit the maxillary growth. The aim of this case report was to present a method of correcting soft tissue defects after conventional surgery in cleft lip and palate patient by using combined laser surgery and orthodontic appliance. A bilateral cleft lip and palate patient with a clinical problem of shallow upper anterior vestibule after alveolar bone graft received a vestibular extension by using CO 2 laser with ablation and vaporization techniques at 4 W and continuous wave. A customized orthodontic appliance, called a buccal shield, was placed immediately after surgery and retained for 1 month to 3 months until complete soft tissue healing. The procedures were performed 2 episodes. Both interventions used the same CO 2 laser procedure. The first treatment resulted in partial re-attachment of soft tissue at surgical area. The second laser operation with the proper design of buccal shield providing passive contact with more extended flange resulting in a favorable outcome from 1 year follow up. Then the corrective orthodontic treatment could be continued effectively. The CO 2 laser surgery was a proper treatment for correcting soft tissue defects and the design of buccal shield was a key for success in molding surgical soft tissue.

Full Text Available The relationship between occlusion and TMJ has been the subject of considerable controversy. It is widely believed that the TMJ signs and symptoms such as Joint pain, clicking, locking and headaches are secondary to abnormalities of occlusion, with actual derangement being uncommon. This case report is to put forward the hypothesis that, type I TMD is often due primarily to occlusal interferences for which orthodontic treatment is generally effective. This case report underlines the significance of fixed orthodontic appliance along with the anterior bite plane splint used in correction of type I TMD.
Full Text Available The aim of this case presentation is to outline some of the advantages that an adjunct orthodontic treatment can offer in a comprehensive oral rehabilitation of an adult patient. Adjunctive orthodontic treatment is usually limited to a dental arch or to a group of teeth within an arch. The purpose of dental movements in this case will be to position the teeth in a way that makes the restoration or replacement of damaged or missing teeth as easy as possible and with minimal dental tissue sacrifice. In addition, the improved position of the teeth will create a healthier periodontal environment that is easier to maintain over time.

To investigate the expression of osteocalcin during rapid orthodontic tooth movement aided by alveolar surgery in beagle dogs. Eight male beagles were used, and bilateral mandibular second premolars were extracted for distalization of the first premolars against the third premolars by orthodontic NiTi coil spring with a force of 100 gm. Right and left mandibular sides were randomly assigned to experimental and sham sides, and alveolar surgery was performed only on the experimental side to reduce the osteal resistance on the mesial side of the extraction socket. Distance of tooth movement was measured once a week during the first 4 weeks. Two beagles were sacrificed after 1, 2, 4, and 8 weeks of orthodontic force application, and expression of osteocalcin was demonstrated by immunohistochemistry and quantified with computer-aided image analysis. The average total movement of the first premolars in 4 weeks on the experimental side (1.868 +/- 0.022 mm) was approximately double that on the sham side (1.008 +/- 0.057 mm). As regards the average total anchorage loss, no significant difference (P > .05) was revealed. Dynamic osteocalcin concentrations presented at 4 time periods (P osteocalcin on the experimental sides was higher than the corresponding sham sides, and that on the compression sites higher than the corresponding tension sites (P orthodontic tooth movement, and promote the rate of bone remodeling as revealed by the expression of osteocalcin.

Corticotomy found to be effective in accelerating orthodontic treatment. The most important factors in the success of this technique is proper case selection and careful surgical and orthodontic treatment. Corticotomy facilitated orthodontics advocated for comprehensive fixed orthodontic appliances in conjunction with full thickness flaps and labial and lingual corticotomies around teeth to be moved. Bone graft should be applied directly over the bone cuts and the flap sutured in place. Tooth movement should be initiated two weeks after the surgery, and every two weeks thereafter by activation of the orthodontic appliance. Orthodontic treatment time with this technique will be reduced to one-third the time of conventional orthodontics. Alveolar augmentation of labial and lingual cortical plates were used in an effort to enhance and strengthen the periodontium, reasoning that the addition of bone to alveolar housing of the teeth, using modern bone grafting techniques, ensures root coverage as the dental arch expanded. Corticotomy facilitated orthodontics is promising procedure but only few cases were reported in the literature. Controlled clinical and histological studies are needed to understand the biology of tooth movement with this procedure, the effect on teeth and bone, post-retention stability, measuring the volume of mature bone formation, and determining the status of the periodontium and roots after treatment.

In this, the third part of the series, aesthetic orthodontic treatment will be considered. The previous two articles have looked at invisible orthodontics with Invisalign and lingual brackets. This article will discuss the properties and use of aesthetic brackets, along with examples of orthodontic treatment cases using the aesthetic brackets. Increasing demand for aesthetics during orthodontic treatment has resulted in a significant increase in the use of aesthetic brackets. Clinicians need to be aware of the benefits and drawbacks of aesthetic brackets.
Full Text Available Introduction: About 0.1% of the population suffers from necrotizing ulcerative gingivitis, a disease of rapid progression and acute manifestation, which may progress to necrotizing ulcerative periodontitis and eventually to bone sequestration and loss of gingival tissue. Case report: A 21-year-old female patient undergoing orthodontic treatment for six months, diagnosed with necrotizing ulcerative gingivitis due to acute pain in the gingival tissue, spontaneous bleeding, halitosis and abundant plaque. The treatment was conservative and effective, obtaining total remission of the lesion after seven days and three months of postoperative follow-up. Conclusion: Today there are no epidemiological or clinical reports that support the relationship of necrotizing ulcerative gingivitis and orthodontic treatment. Prevention is critical to the success of the treatment, which is why the dentist should recognize the clinical features of necrotizing ulcerative gingivitis to raise awareness of its risks in the orthodontic patient.

With an increasing number of adult patients coming to the orthodontic clinic, the orthodontic professional is constantly looking for ways to accelerate tooth movement. Surgical intervention to affect the alveolar housing and tooth movement has been described in various forms for over a hundred years. However, it is the spirit of interdisciplinary collaboration in orthodontics has expanded the realm of traditional orthodontic tooth movement protocols. Periodontal accelerated osteogenic orthodontics (PAOO) is a clinical procedure that combines selective alveolar corticotomy, particulate bone grafting, and the application of orthodontic forces. This procedure is theoretically based on the bone healing pattern known as the regional acceleratory phenomenon (RAP). PAOO results in an increase in alveolar bone width, shorter treatment time, increased post treatment stability, and decreased amount of apical root resorption. Tooth movement can be enhanced and cases completed with increased alveolar volume providing for a more intact periodontium, decreased need for extractions, degree of facial remodeling and increased bone support for teeth and overlying soft tissues, thereby augmenting gingival and facial esthetics.The purpose of this article is to describe the history, biology, clinical surgical procedures, indications, contraindications and possible complications of the PAOO procedure. Key words:Periodontics, corticotomy, osteogenic, orthodontics.

Whereas the psychosocial benefits of orthognathic treatment for the individual patient are established, there is little data relating to social perceptions in relation to changes in facial appearance as a result of combined orthodontic and orthognathic treatment. This study aimed to investigate the social impact of combined orthodontic-orthognathic surgical correction for class III malocclusion in Caucasian subjects. This cross-sectional study compared perceptions of facial appearance prior to and after orthognathic correction of class III malocclusion. Eighty undergraduate students were shown photographs of four Caucasian subjects (2 male and 2 female) pre- and post-orthognathic class III correction. Observers were asked to rate these subjects in relation to four different outcomes: (i) social competence (SC); (ii) intellectual ability (IA); (iii) psychological adjustment (PA); (iv) attractiveness. A mixed-model analysis of variance (ANOVA) was calculated to determine the effect of each variable. Statistically significant differences were found in ratings of the same face before and after treatment. After treatment, faces were rated as more psychologically adjusted, more sociable, more likely to be successful and more attractive; with the mean psychological adjustment rating being associated with the most change (before treatment=8.06 [SD 2.30]; after treatment=6.64 [SD 2.03], t=2.04, pclass III malocclusion in Caucasians, individuals are rated by young adults as being better adjusted both psychologically and socially, more likely to be successful and more attractive.

Each case is complemented by information on the disease affecting the patient and the management of the case shown, including therapy and follow-up. This educational text is targeted at all medical professionals faced with a variety of diagnostic and therapeutic problems affecting infants and children. (orig.)
Full Text Available Today orthodontic treatment is in growing demand and is not limited to a specific age or social group. The nature of orthodontic treatment is such that the orthodontic wires and appliances, which are used to apply force and move the teeth, are exposed to the oral cavity. Shaping and replacing these wires in oral cavity are the major assignments of orthodontist on appointments. Therefore, we can say that orthodontic treatment requires working with dangerous tools in a sensitive place like oral cavity which is the entrance of respiratory and digestive systems. In this paper, a case of ingesting a broken orthodontic wire during eating is reported, and also necessary remedial measures at the time of encountering foreign body ingestion or aspiration are provided.

Implant placement is often necessitated for replacement of teeth with pathologically damaged alveolar bone due to periodontitis or traumatic injury. Surgical augmentation of resorbed bone has many limitations, including lower efficacy of vertical augmentation than horizontal augmentation, as well as morbidity associated with grafting procedure. Orthodontic therapy has been proposed as a useful method for augmenting the resorbed alveolar bone and reforming aesthetically appealing gingival margin, prior to implant placement. This narrative review summarizes the available evidence for the application of orthodontic strategies that can be used as adjunct in selected cases to augment bone volume for the future implant site and maintain space for the prosthetic parts of the implant. These are (1) orthodontic extrusion of compromised teeth to generate vertical bone volume and enhance gingival architecture, (2) tooth preservation and postponing orthodontic space opening to maintain bone volume in future implant site, (3) orthodontic implant site switching to eliminate the deficient bone volume or risky implant sites, and (4) the provision of a rigid fixed-bonded retainer to maintain the implant site. Although there are no randomized controlled clinical trials to evaluate the efficacy of orthodontic therapy for implant site development, clinical case reports and experience document the efficacy of orthodontic therapy for this application.

Iatrogenic trauma though not serious is very common in dental practice. Orthodontic treatment can inflict such injuries as they are prolonged over a long period of time. Ill-fabricated orthodontic appliances, such as wires and brackets, or the patients' habits such as application of constant pressure over the appliance can traumatize the adjacent oral soft tissues. In rare cases, these appliances can get embedded into the mucosa and gingival tissues. This case report describes one such case of iatrogenic trauma to the palatal mucosa due to entrapment of a tongue spike appliance and its surgical management.

Impacted canines require a combination of both surgical and orthodontic management. In this study, patients treated for bone-impacted canines of the hard palatal were evaluated to assess which radiographic factors influenced the feasibility to move impacted maxillary permanent canines from the hard palate into the alveolar arch. Eighty patients aged 12 to 24 (average 16 years) were treated surgically and orthodontically to align 146 bone-impacted canines of the hard palate (from 1994 to 2008). Factors such as age, sex, angulation of the canine to the midline (CAM), anomaly of the canine root (RA), overlap of the adjacent lateral incisor root (OALIR), and ratio of root formation (RRF) upon treatment were documented. Radiographic records and demographic data were assessed. The following radiographic measurements of canine position were made from the orthopantomogram (OPG): (1) angulation to the midline, (2) anteroposterior position of the root, (3) overlap of the adjacent incisor. RA or dilaceration was assessed from the OPG, maxillary occlusal (MO), and periapical (PA) radiographs. Whether the impacted canine had responded to surgical exposure and was orthodontically aligned, or surgically removed and discarded was also recorded. The data were analyzed to assess and correlate significance. Eighty patients aged 12 to 24 (19 males and 61 females) with 146 bone-impacted permanent canines of the hard palatal were treated. One hundred and three teeth (70.54%) had responded to surgical exposure and orthodontic alignment within 9 to 12 months. Forty-three impacted canine teeth (29.46%) had to be surgically removed because of ankylosis and no movement after 8 to 9 months using 50 to 60 g of traction force via elastic chains. Data analysis via chi-square and Pearson correlation tests showed that as the CAM increased (> 45 degrees), the canine was more likely to be unresponsive to treatment (P half the root) of the adjacent lateral incisor root (OALIR) via the canine crown

Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior area. Direct resin bonding along with orthodontic movement of teeth allows space closure and midline correction, consequently, creating a better esthetic result.

Full Text Available INTRODUCTION: Torus palatinus is a specific name to identify exostoses developed in the hard palate along the median palatine suture. Despite of not being a pathological condition, its presence requires attention and knowledge regarding its management. Surgical removal of exostoses is indicated when the patient frequently traumatizes the area of palatine torus during mastication and speech or when it is necessary for the rehabilitation of the upper arcade with complete dentures. OBJECTIVE: The aim of this article is to present three cases of Torus palatinus and to discuss the management of them. CASE REPORT: In the first case, a 57-year-old Caucasian man sought oral rehabilitation of his edentulous maxilla but presented a hard nodules in the hard palate; in the second case, a 40-year-old Caucasian woman was referred for frequent trauma of palatal mucosa during mastication, aesthetic complaint, and discomfort caused by the trauma of her tongue in this area; and in the third case, a 45-year-old Caucasian woman presented with a lesion on the palate that caused difficulty swallowing. When the Torus palatinus was impairing the basic physiological functions of the patients, all cases were surgically treated, improving the patients' quality of life. FINAL CONSIDERATION: The dentist should be properly prepared to choose the best from among the existing surgical approaches for each individual lesion in order to improve the results and avoid possible complications.

The aim of this retrospective cohort study was to evaluate the postoperative stability of sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy (IVRO) in pre-orthodontic orthognathic surgery (POGS) for skeletal Class III malocclusion. Thirty-seven patients (SSRO, n = 18; IVRO, n = 19) who underwent bimaxillary surgery were divided into two groups according to the type of surgery. During the postoperative period, there were no significant differences in anterior and superior movements of the mandible at point B between the two groups, but occlusal plane angle of the SSRO group significantly decreased more than that of the IVRO group (P = 0.003). Only the SSRO group showed a linear relationship between the amount of postoperative horizontal and vertical movements of the mandible (R(2) = 0.254; P = 0.033), indicating that the amount of postoperative upward movement of the mandible increased as the amount of postoperative forward movement increased (r = -0.504; P = 0.033). The mandible after SSRO in POGS rotated counterclockwise due to rigid fixation between two segments, whereas the mandible after IVRO without rigid fixation in POGS moved mainly in a superior direction. These differences must be considered before surgery to ensure postsurgical stability for patients with mandibular prognathism. Copyright © 2016. Published by Elsevier Ltd.

Orthodontic preparation for orthognathic surgery requires correcting mal-occlusions and coordination of arcades. In addition to improving the aesthetics, these treatments can ensure the achievement and sustainability of prosthetics and/or implants. Nevertheless, periodontal structures are easily damaged. Orthodontic displacement can only be applied in the absence of inflammation or weakened periodontal structure. An early detection of periodontal risk should be achievable by prescribers of a surgical-orthodontic treatment. Simplified periodontal examination, with easily detectable warning signs, will help to identify the periodontal risk. Although periodontal treatment follows current "non invasive" trend, some procedures remain necessary to prevent and/or remedy periodontal defects or diseases, such as mineral periodontal reinforcement corticotomy. It is essential that the patient meets all the practitioners to plan and assess the extent of the constraints necessary to optimize results, before starting orthodontic treatment combined with orthognathic surgery. Any periodontal complication (even minor) will be considered as a failure, regardless of good aesthetic and functional results. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

This article describes the complex dental treatment of a 43-year-old man with skeletal Class II, mandibular asymmetry, severe brachyfacial pattern, Class II Division 2, canting of the occlusal plane, and an increased curve of Spee. To achieve optimal results, we adopted a multidisciplinary approach to treatment, involving periodontics, oral surgery, orthodontics, maxillofacial surgery, and prosthetics specialists. After periodontal treatment, miniscrews were placed to correct the occlusal plane canting and the excessive curve of Spee with orthodontic treatment. The surgical treatment plan consisted of a bilateral asymmetric sagittal split osteotomy for mandibular advancement and genioplasty. The patient had an infection after the surgery at the site of the right fixation plate, so the plate was removed, and active orthodontic treatment was continued and finished. Mandibular first molar implants and maxillary ceramic crowns using the Digital Smile Design method (Digital Smile Design, Doral, FL) were placed at the end of orthodontic treatment. The patient was satisfied with the treatment results and with his facial and dental appearance, as well as his oral function. The 2-year follow-up pictures show a stable result both esthetically and functionally. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

The authors describe their experience with surgical treatment of benign rare lymph proliferation - Castlemans disease (CD). It occurs in unicentric and multicentric forms. The very low incidence of the disease makes it very difficult to design larger prospective studies. Cases of two leading localizations of the unicentric form of CD - intrathoracic and retroperitoneal with special emphasis on the preoperative diagnosis and imaging options are described. This article underlines the curative potential of surgical treatment where a complete resection of the affected lymph node leads to eradication in almost 100% of the cases. The discussion is focused on the forms of CD - different localization, clinical symptoms and course of disease. It discusses the differential diagnosis, particularly difficult in the multicentric form, emphasizing the need to exclude malignant lymphoma. The etiopathogenesis of the disease is presented, mentioning its association with HIV (Human Immunodeficiency Virus) infection and HHV-8 (Human herpers virus 8) infection and the importance of overproduction of proinflammatory cytokines. The importance of surgical therapy for the unicentric form of CD is highlighted as compared to the multicentric form, where the surgeon´s task involves taking a biopsy - required for an accurate diagnosis.Key words: Castlemans disease - lymphoproliferation - lymphadenopathy - surgical treatment.

Aesthetic improvement is an essential goal of treatment of facial asymmetry, and it is often difficult to achieve. Reliable three-dimensional measurements are required to support outcome studies. In this study, 15 white adult subjects, 9 females and 6 males, with maxillomandibular asymmetry and malocclusion were studied. The patients were treated with orthodontics and different surgical procedures in single or multiple steps. All patients received double-jaw surgery, except 1 patient who underwent only maxillary osteotomy. Nine of the 15 patients received additional procedures (genioplasty and rhinoplasty) to achieve better symmetry. Posterior-anterior and lateral cephalometry and three-dimensional facial surface data were obtained before (T0) and 1 year (T1) after surgery. Scan data at T0 and T1 were pooled by electronic surface averaging to obtain the mean pretreatment and posttreatment facial model. A symmetric model was constructed by averaging the actual T0 scans and their mirrored models to obtain the virtual optimal symmetric face. Different linear and angular measurements were then calculated for comparison of the mean T0 and T1 models. The normalization of facial proportion and a high increase in symmetry were evident. Residual defects were documented in the postoperative symmetry of the chin. Treatment of facial asymmetry, combined with dental occlusion problems, is still a challenge for maxillofacial surgeons. Orthognathic surgery provides an important improvement of symmetry, but further refinements of technique are still required. Three-dimensional evaluation results in an effective method to support outcome studies on the surgical correction of complex facial deformities.

Despite the growing number of adults interested in improving their smiles through orthodontic treatment, the visual impact and the duration of the treatment itself are frequently obstacles to patient acceptance. A treatment that is fast and less visible is a desirable option that adult patients often request of their orthodontists. Presented in this case report, which involves a young woman who wanted treatment completed in a limited amount of time, is a new application of a minimally invasive surgical approach to accelerate orthodontic movement combined with a simplified 2-dimensional lingual orthodontic treatment to resolve mild crowding in the anterior region, otherwise known as the "social six.".
Full Text Available Background: Periodontally accelerated osteogenic orthodontics is a clinical procedure that combines selective corticotomy, particulate grafting, and application of orthodontics. It reduces treatment time, increases stability of teeth, and prevents relapse of orthodontic tooth moment. The present study was aimed to explore the clinical and radiographic comparison of bone density changes, retraction time differences in buccal and palatal corticotomy with buccal corticotomy which was done by surgical bur. Materials and Methods: A split-mouth was designed in 16 patients and divided into right (buccal and palatal corticotomy (Group I, left (buccal corticotomy (Group II sides. In both groups, decortication was done with surgical bur. Clinical parameters such as gingival bleeding index and probing pocket depth were recorded at baseline, 1 month, 3 months, and 6 months. Bone density changes were measured by computed tomography at baseline and after 6 months after surgery and also used for evaluating differences in bone density changes between two groups. Retraction time differences were also measured in both groups. Results: In both groups, there was significant difference between bone density changes at baseline and 6 months after surgery. However, the difference between two groups was not significant. The difference in clinical parameters between two groups was not significant. The difference in retraction time differences was not significant. Conclusion: Within limits of the study, it may be concluded that there was difference between bone density changes before and 6 months after surgery. Difference in total treatment time found to be no significant between two groups.

The effect of the Twin Block functional orthodontic appliances is mostly dento-alveolar with small skeletal effect. There are certain clinical indications where functional appliances can be used successfully in class II malocclusion e.g. in a growing patient. The use of these appliances is greatly dependent on the patient’s compliance and they simplify the fixed appliance phase. In this case, a 13-year old adolescent was treated with Twin Block appliance followed by fixed appliance to detail the occlusion. The design and treatment effects were demonstrated in this case report. PMID:24151413

Functional and esthetic results can improve significantly when a combined prosthodontic-orthodontic treatment approach is employed in cases requiring extensive oral rehabilitation. The patient presented in this case report was treated in his late teens with dental implants as a replacement for his maxillary incisors. Ten years later, the entire maxillary anterior segment was in infraocclusion compared to the rest of the dentition and lip line. Since prosthodontic follow-up treatment alone could not achieve an optimal functional and esthetic outcome, the patient was treated orthodontically prior to renewing the restoration. A fixed appliance was used to intrude the mandibular anterior teeth as well as vertically align the infrapositioned maxillary lateral incisors.

Background: The specialization of forensic odontology is fast emerging as a branch that helps in personal identification of both living as well as dead individuals and also in crime scene investigations. Establishing a person’s identity can be a challenging task in cases of road accidents or acts of terrorism or mass disaster scenario. It is an established fact that palatal rugae are unique for each individual and can be reliably used in the forensic field for personal identification. The present study was undertaken to evaluate the post-treatment stability of palatal rugae pattern in individuals subjected to orthodontic treatment with and without extractions and palatal expansion. Materials and Methods: A total of 137 pre- and post-orthodontically treated casts of patients were obtained from our institute, which were divided into 50 cases each of extraction and non-extraction, 37 cases of palatal expansion involving both extraction and non-extraction. Palatal rugae patterns of all the cases were compared pre- and post-treatment. Results: Chi-square test was applied for comparison of changes with respect to shape of rugae patterns. Maximum changes were seen in palatal expansion and extraction group and minimum changes in non-extraction group both on right and left sides. All three groups were compared involving all three parameters by Chi square test. About 89.19% and 84% of the study group showed changes in palatal expansion and extraction cases respectively. Although, a 62% of study subjects showed changes in non-extraction group with a P = 0.00041. Conclusion: Orthodontic treatment has an impact on the stability of palatal rugae so investigator should be aware of this fact when analyzing for identification reasons. PMID:25395801

Full Text Available Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior area. Direct resin bonding along with orthodontic movement of teeth allows space closure and midline correction, consequently, creating a better esthetic result.

This case report refers to an 11-year-old boy with avulsion of the upper left central and lateral incisors. The teeth were replanted after 4 h, splinted with a semi-rigid splint for 12 days, and then endodontically treated. Severe progressive root resorption was seen after 2 years and the teeth were extracted. The boy had a normal occlusion with spacing in both jaws and slight protrusion of the anterior teeth. The treatment objectives were to close some of the spaces by mesial movement of the buccal segments in the upper jaw to minimize bone loss for a future single osseointegrated implant. Fixed appliance in combination with a removable plate was used for the mesial movements, levelling, and alignment of the upper jaw. Fixed appliance in the lower jaw and Class II traction were used for the final adjustment of the occlusion. A good occlusion with coincident upper and lower midlines and up-righted anterior teeth were achieved. A Maryland bridge was performed as a temporary solution for a future osseointegrated implant.

The Hasund cephalometry gives important information about the position of the mandible and maxilla to each other and to the cranium in horizontal and vertical plane, and about the expecting mandibular growth. The aim of the study was to examine the reliability of the Hasund growth analysis on the basis of cephalogramms. The data of eighteen children having been treated with four premolar extraction in the growing period were compared. At the start of treatments the children's average age was 10 (8.5-11.5) years. Figures from the cephalometry were analysed by an orthodontic diagnostic program. According to our results the predicted growth was justified in 14 cases and contrary mandibular development was found in 4 cases. Beyond the limits of this study we concluded that the Hasund growth analysis gives mainly a reliable prognosis on predicting mandibular development. In diagnostic procedures this analysis should be followed for a successful decision-making in treatment plan. However, during the orthodontic treatment the prognostic results have to be monitored by using further cephalometric evaluations in a time-scales of a year.

Fusion is one of the developmental dental anomalies in which two adjacent teeth are joined at the crown level forming a single tooth with an enlarged crown. Fusion causes some clinical problems such as unaesthetic appearance, pain, caries, and malocclusion. The management of fusion often needs multidisciplinary approach to give best possible esthetic and functional outcome. This paper reports a case of 9-year-old boy with fused maxillary left central and lateral incisors who was treated with ...
It is a commonly held misconception among Irish dentists that only minor malocclusions can be treated with lingual appliances. This article demonstrates the use of contemporary completely customised lingual orthodontic appliances to treat a diverse range of malocclusions, to a satisfactory level, and thereby may disabuse clinicians of the belief that only minor malocclusions can be treated with lingual appliances.

We present a case of bialveolar protrusion treated with second premolar extraction. The patient did not agree to placement of a visible labial appliance or to the use of a headgear. Therefore, a lingual orthodontic appliance was used, and titanium screws were placed into the buccal alveolar bone for orthodontic absolute anchorage and support of en masse retraction of the anterior teeth. Cephalometric superimposition and panoramic radiographs showed little anchorage loss and good occlusion at the end of treatment. Our results suggest that lingual treatment combined with a screw-type implant anchorage provides reliable and comfortable results for those seeking invisible treatment.

A revascularization procedure was shown to be the best alternative therapy for immature teeth with necrotic pulp and apical infection. A 12 year old female with a history of trauma to her upper central incisor and a sinus tract was referred for endodontic treatment. She was an active orthodontic patient and had undergone regenerative endodontic treatment for the past 2 years. Clinical examination revealed no response to sensibility, percussion, and palpation tests. The preoperative radiograph showed an open apex and apical rarefaction. The case was diagnosed as previously treated tooth with asymptomatic apical periodontitis. Regenerative endodontic retreatment was performed, and the case was followed for 3 years. Clinical, radiographic, and cone-beam computed tomography follow-up examination revealed an asymptomatic tooth, with evidence of periapical healing and root maturation.

Full Text Available The aim of this case report was to introduce an appliance for correcting severe rotation of anterior teeth in the mixed dentition period. A 9-year-old Iranian boy with a mixed dentition Class I malocclusion complained of a severely rotated of upper right central incisor. There was a mesiodens between the central incisors. The supernumerary tooth was first extracted and then a Whip appliance which is composed of a removable plate, a cantilever spring and a central bracket on the rotated tooth was utilized. After 8 months, the upper right central incisor was orthodontically brought into proper alignment. Circumferential supracrestal fibrotomy was performed on the overcorrected tooth. One week after surgery, the device was removed and the retention was started. The whip appliance is a removable appliance that can effectively correct severe rotation of anterior teeth especially during the mixed dentition period.

Full Text Available Moderate induced hypothermia has become standard of care for children with peripartum hypoxic ischaemic encephalopathy. However, children with congenital abnormalities and conditions requiring surgical intervention have been excluded from randomised controlled trials investigating this, in view of concerns regarding the potential side effects of cooling that can affect surgery. We report two cases of children, born with congenital conditions requiring surgery, who were successfully cooled and stabilised medically before undergoing surgery. Our first patient was diagnosed after birth with duodenal atresia after prolonged resuscitation, while the second had an antenatal diagnosis of left-sided congenital diaphragmatic hernia and suffered an episode of hypoxia at birth. They both met the criteria for cooling and after weighing the pros and cons, this was initiated. Both patients were medically stabilised and successfully underwent therapeutic hypothermia. Potential complications were investigated for and treated as required before they both underwent surgery successfully. We review the potential side effects of cooling, especially regarding coagulation defects. We conclude that newborns with conditions requiring surgery need not be excluded from therapeutic hypothermia if they might benefit from it.

Full Text Available Orthodontic implants have become a reliable method in orthodontic practice for providing temporary additional anchorage. These devices are useful to control skeletal anchorage in less compliant patients or in cases where absolute anchorage is necessary. There are a great number of advantages in this new approach which include easy insertion, decreased patient discomfort, low price, immediate loading, reduced diameter, versatility in the forces to be used, ease of cleaning, and ease of removal. However, a proper management of the screws by the practitioner is necessary in order to increase the success rate of the technique. The purpose of this paper is to update practitioners on the current concepts of orthodontic implants and orthodontic mechanics.

This case report discusses a rare side effect associated with the use ofa fixed quad helix orthodontic appliance. A 14-year-old healthy girl presented with a painful enlarging mass on her tongue, which was causing distress to both her and her parents. Investigations confirmed that the mass was a pyogenic granuloma and management involved surgical excision of the mass and removal of the quad helix appliance. At least once previous case associated with an orthodontic quad helix appliance has been reported in the literature.

There are 2 major drawbacks to the classic orthodontic-surgical approach for resolution of impacted teeth in adults: appearance and duration of treatment. This case report illustrates the lingual orthodontic treatment of an adult with an impacted maxillary canine; absolute anchorage was achieved with a miniscrew placed in the palate. The combination of invisible appliances and a nondental anchorage system is particularly useful in adults and should make treatment available to more patients.

The use of orthodontic treatment in adult patients is becoming more common and these patients have different requirements specially regarding duration of treatment and facial and dental aesthetics. Alveolar corticotomy is an effective means of accelerating orthodontic treatment. This literature revision include an historical background, biological and orthodontic fundamentals and the most significant clinical applications of this technique. Orthodontic treatment time is reduced with this technique to one-third of that in conventional orthodontics. Alveolar bone grafting of labial and palatal/lingual surfaces ensures root coverage as the dental arch is expanded. Corticotomy-assisted orthodontics has been reported in a few clinical cases, and seems to be a promising adjuvant technique, indicated for many situations in the orthodontic treatment of adults without active periodontal pathology. Its main advantages are reduction of treatment time and postorthodontic stability. Further controlled prospective and histological studies are needed to study tooth movement, post-retention stability, and microstructural features of teeth, periodontium, and regenerated bone after using this procedure. Key words:Corticotomy, osteotomy, accelerated orthodontics.

An orthodontic treatment usually involves a long process which often represents an obstacle for patients. To overcome this problem, surgical techniques have been developed to support and accelerate the orthodontic treatment. Two systematic reviews of the literature on clinical research and animal experiments were carried out in order to draw reliable conclusions about the effectiveness of the various surgical techniques. A total of 18 clinical studies and 22 animal experimental studies were analysed. In both reviews of the literature, a study was made of whether the surgical techniques resulted in an accelerated rate of tooth movement and which complications may be observed. In addition, which biological mechanisms take place during surgically facilitated orthodontics was investigated. Both reviews reported accelerated tooth movement with minimal complications after surgical procedures in comparison to conventional orthodontics. An increase in catabolic and anabolic activities was observed. It has to be concluded that based on the quality of the current literature there is still insufficient information for general conclusions and that more standardised prospective research is necessary for a reliable conclusion about the optimal method of treatment.
Full Text Available Context: An accurate method for assessing the contour, symmetry, and stability of the dental arches is a prerequisite for investigations of form-function relationship. Various approaches to the study of arch shape have been described, but they were either best suited for simple visual analysis or when maximal accuracy was desired. The cost and complexity of the techniques and the equipment employed for assessing the arch shape preclude their general application. Hence, the present study was undertaken to evaluate the changes in palatal contour in orthodontically treated cases using scanned maxillary casts. Aims: The aim of the study was to evaluate the changes in palatal contour in orthodontically treated cases using scanned maxillary casts. Settings and Design: Retrospective study. Subjects and Methods: One hundred pre- and post-treatment maxillary casts of fifty completed cases in permanent dentition phase managed with fixed mechanotherapy were included in the present study. The landmarks were identified; scanning of the casts was done using flatbed scanner, and the palatal contoural changes were measured in three-dimensions after superimposing the pre- and post-treatment scanned images on medial points of the third palatal rugae which were considered as stable landmark. Statistical Analysis Used: Paired t-test. Results and Conclusions: There is statistically significant difference between the pre- and post-treatment width, anteroposterior length, and depth of the palate in orthodontically treated cases.

Full Text Available Appearance is the most important motivating factor for patients seeking orthodontic treatment and is self-evident that these patients would prefer an appliance that is less visible. Lingual "invisible" Appliances offer the best option to the patient seeking aesthetic correction for their malocclusion. A group of such patients who do not want their appliances to be visible also require surgical correction. Lingual appliance being comparable to the labial counterpart provides the opportunity of hiding appliances for patients requiring Orthognathic surgical correction for their condition. This case report depicts the successful treatment of a patient using lingual appliance in conjunction with anterior maxillary osteotomy.

The management of open bite malocclusions creates controversy when treatment approach and long-term stability are considered. Tongue size, posture and habits have been associated as aetiologic and compounding factors. Reduction tongue surgery has therefore been advocated as an aid in treatment, especially when the open bite is accompanied by perceived macroglossia. The present article describes a clinical case of a 10-year-old girl who started treatment in the mixed dentition with an excessive open bite and speech defects. A combination of orthodontics and a partial glossectomy was necessary to successfully address the open bite associated with an enlarged tongue. The need for orthognathic surgery treatment was eliminated and the patient was satisfied with the post-treatment aesthetics, function and speech. After 13 years of follow-up, a stable occlusion was maintained with only minor relapse.

External apical root resorption is an adverse effect of orthodontic treatment. It reduces the length of root and breaks the integrity of teeth and dental arch. Orthodontics is the only dental specialty that clinically uses the inflammatory process to correct the mal-aligned teeth. Hence, it is necessary to know the risk factors of root resorption and do everything to reduce the rate of root resorption. Hence, all predisposing factors which are systemic as well as local should be considered be...
The limits of an orthodontic treatment are often set by the lack of suitable anchorage. The mini-implant is used where conventional anchorage cannot be applied and not as a replacement for conventional anchorage. In patients with lack of teeth and reduced periodontium, skeletal anchorage allows...... the optimal positioning of the teeth following rehabilitation. Patients with need for inconsistent tooth movements, borderline surgical cases, can benefit from the use of the mini-implant and regeneration of alveolar process by tooth movement in edentulous molar regions and using mini-implants as anchorage...... will improve the reconstruction possibilities. The mini-implant has widened the orthodontic possibilities....

Turner syndrome is caused by complete or partial absence of one X chromosome. These patients usually have a delay in growth and altered body proportions, causing sexual infantilism, short stature, delayed bone maturation, and variations in craniofacial morphology, among other systemic complications. The skeletal features associated with this syndrome include maxillary growth reduction with midface hypoplasia; mandibular micrognathia; high, narrow palate; V-shaped maxillary arch; and open bite. This case report shows a two-phase orthodontic treatment in a patient with Turner syndrome with a Class II malocclusion and severe deep bite, which is an unusual feature in patients with this disease. A conventional orthodontic treatment was performed, and after 20 months in retention the patient remains stable.

There has always been concern in determining the relationship between orthodontic tooth movement and the consequent biological costs to the periodontium and tooth root. The possibility of evaluating the tooth and bone morphology by CBCT allows more accurate analysis of qualitative and quantitative aspects of these processes. This paper presents a case report of a 20-year-old male patient with Class III malocclusion and hyperdivergent facial pattern, who was surgically treated. A significant amount of labial movement of mandibular incisors was performed during orthodontic treatment before surgery. CBCT was used for evaluation of buccal and lingual bone plates before and after tooth decompensation. The changes in the bone insertion level of maxillary and mandibular incisors in the present case encourage a reflection on the treatment protocol in individuals with dentoskeletal discrepancies.

Retrospective analysis. The objective of this study was to describe the microbiology of surgical site infection (SSI) in spine surgery and relationship with surgical management characteristics. SSI is an important complication of spine surgery that results in significant morbidity. A comprehensive and contemporary understanding of the microbiology of postoperative spine infections is valuable to direct empiric antimicrobial treatment and prophylaxis and other infection prevention strategies. All cases of spinal surgery associated with SSI between July 2005 and November 2010 were identified by the hospital infection control surveillance program using Centers for Disease Control National Health Safety Network criteria. Surgical characteristics and microbiologic data for each case were gathered by direct medical record review. Of 7529 operative spine cases performed between July 2005 and November 2010, 239 cases of SSI were identified. The most commonly isolated pathogen was Staphylococcus aureus (45.2%), followed by Staphylococcus epidermidis (31.4%). Methicillin-resistant organisms accounted for 34.3% of all SSIs and were more common in revision than in primary surgical procedures (47.4% vs. 28.0%, P = 0.003). Gram-negative organisms were identified in 30.5% of the cases. Spine surgical procedures involving the sacrum were significantly associated with gram-negative organisms (P spine. Cefazolin-resistant gram-negative organisms accounted for 61.6% of all gram-negative infections and 18.8% of all SSIs. Although gram-positive organisms predominated, gram-negative organisms accounted for a sizeable portion of SSI, particularly among lower lumbar and sacral spine surgical procedures. Nearly half of infections in revision surgery were due to a methicillin-resistant organism. These findings may help guide choice of empiric antibiotics while awaiting culture data and antimicrobial prophylaxis strategies in specific spine surgical procedures. 3.

Removable orthodontic appliance may be indicated in the management of anterior proclination and increased overjet especially in the younger age group. Generally, proclined maxillary incisors are prone to trauma in young active children. This makes prompt preventive and interceptive intervention very necessary. This condition is complicated in the event of associated trauma to such tooth/teeth that could require orthodontic tooth movement. The first report involves a 12-year-old boy who presented three years ago with loss of his two central incisors due to traumatic avulsion. The second report is a 10- year-old boy who presented a year ago with a dento alveolar abscess in relation to a long standing Ellis class III and class II fractures on the maxillary right and left central incisors, respectively. In both cases two different innovative management procedures were undertaken which combined restorative and orthodontic procedures concurrently, which helped the children psychologically in school. The first has been discharged to continue with the appliance as both a retainer and a denture while the second has completed an acceptable dental restoration and is still receiving orthodontic care with satisfactory progress. These innovative procedures yielded good results. Both patients and parents were very co-operative and appreciative of the outcomes.

Restoration of a traumatically injured tooth presents a clinical challenge for a predictable aesthetic outcome. This case report describes a multidisciplinary approach of a subgingivally fractured permanent maxillary central incisor. A removable orthodontic appliance was used for orthodontic extrusion of root, and surgical gingival recontouring was done with electrocautery to reestablish the biological width. Form and function were restored establishing biological width and esthetics was repaired with porcelain fused to metal crown.

The palatal rugae have been used as a reference landmark and identification marker by orthodontists and forensic analysts. However, the reliability of palatal rugae as a forensic marker remains questionable once an individual is subjected to orthodontic treatment. This study aimed at evaluating the changes in the rugae pattern after nonextraction, extraction, and maxillary expansion orthodontic treatment. The lengths and shapes of palatal rugae were evaluated on the pretreatment and post-treatment dental casts of 168 subjects using the Thomas and Kotze classification. Extraction treatment significantly reduced the second and third rugae lengths (p rugae length was significantly increased after palatal expansion (p rugae remained consistent in all the study groups which may be used as a reliable forensic marker in subjects undergoing orthodontic treatment. However, the use of the lengths of palatal rugae in forensic odontology must be made with caution. © 2016 American Academy of Forensic Sciences.

Full Text Available Dysplastic coxarthrosis is dominate among children orthopedic cases, and its surgical alignment continues to be peracute. Despite the application of advanced therapies and medical treatment, the patients of surgical state case constitute a significant percentage of the total patient number, i. e. from 19 to 35 %. In this article a detailed literature review of surgical alignment methods for deficiency acetabular roof by applying different implants has been described. The authors have proposed applying titanium nickelide materials in the surgical alignment method, as such materials possess the following properties: high corrosion stability, full compatibility with the body tissues, as well as, sufficient porosis providing radial border structure regeneration of acetabular roof, which in its turn, improves the support ability of extermity. In the event of progression of coxarthrosis iliac segment is reserved for the upcoming replacement.
Full Text Available Impaction is an eruptive disturbance characterized by the inability of the teeth to reach from its place of formation to the place of its function. Maxillary central incisor impactions are usually rare as it is one of the first permanent teeth to erupt in the oral cavity. The etiologic factors include the presence of mesiodens, dilacerations of roots, odontomas, fibrous gingiva etc. Impaction of central incisor usually poses a functional as well as an esthetic problem. Treatment options might include surgical intervention or prosthetic rehabilitation, but the best modality would be its orthodontic management. Orthodontic disimpaction in such situations provides a solution to an otherwise long-term esthetic and functional problem. This case report provides a detailed descriptive overview on the orthodontic management of an unfavorably impacted maxillary central incisor (sickle incisor.

Full Text Available Multiple treatment options are available for patients who have impacted incisor. This paper shows a case in which orthodontic as well as surgical considerations in 10-year-old female child were presented in the management of impacted central incisor. The orthodontic treatment plan included three steps – creation of space, exposure of crown, and forced eruption. A unique and innovative technique for orthodontic traction (0.017 × 0.025 TMA wire with palatal extension was employed to move the maxillary incisor into arch, with minimum injury to neighboring soft tissue. After the successful management of impacted teeth, it is very important to periodically review the periodontal condition and stability.

Full Text Available A 16-year-old girl reported with the complaint of missing upper left front teeth and large alveolar cleft defect. The patient was an operated case of cleft lip and palate, managed with primary surgical treatment protocol at age 5 and 11 months and secondary alveolar grafting at 11 years. However, the grafting failed to achieve desired result leaving large residual defect (20 mm. The orthodontic treatment aimed at reduction of alveolar cleft defect, followed by grafting. This was a reverse, innovative plan as usually grafting precedes controlled tooth eruption. A moving tooth carries along its periodontium, and this physiological phenomenon was used to reduce the size of the cleft. Nine months of orthodontics resulted in the eruption of canine through the cleft defect, reducing defect by 12 mm, and the tertiary alveolar grafting obliterated the residual 8 mm defect. Thereafter, orthodontic treatment was completed, and fixed prosthesis provided for missing left lateral incisor for optimal function and esthetics.

Full Text Available A displaced orthodontic elastic separator was proposed as being the source of a gingival abscess that progressed to severe bone loss and exfoliation in a healthy adolescent patient with sound periodontal status prior to commencement of orthodontic treatment. After 1 year of undergoing orthodontic treatment, the patient presented with dull pain and mobility in the left upper permanent molar for which there was no apparent etiology. On clinical examination, the patient had gingival inflammation, associated with a deep pocket and severe mobility (grade III in relation to the same teeth. Radiographic examination of an orthopantomogram and intraoral periapical radiography (IOPAR revealed a chronic periodontal abscess with severe necrosis of the periodontal ligament and severe alveolar bone loss. A radiopaque mass on the distal surface below the cementoenamel junction (CEJ was also observed. The patient was referred to the department of periodontics for assessment and appropriate treatment. On curettage, it was found that there was orthodontic elastic separator which was displaced subgingivally.

Surgical procedures were performed on 25 patients suffering from late-phase intestinal tract disorders induced by irradiation. The primary diseases of these cases were almost exclusively gynecological in nature, such as cancer of the uterine cervix. Symptoms observed in these cases were overwhelming ileus followed by melena, fistulation and free perforation, as well as combination thereof. The most common portion involved was the recto-sigmoidal colon, followed by the ileo-cecum and ileum. As for the relationship of symptoms to the disordered portion, ileus was seen mainly in cases of disorders at the ileocecal portion; melena was observed exclusively in cases of disorders at the rectosigmoidal colon; fistulation was manifested mainly as recto-vaginal fistula or ileo-sigmoidal fistula; free perforation was observed at both the ileum and sigmoidal colon. Colostomy was the most frequent surgical method applied. Only 3 cases were able to undergo enterectomy. Other cases were subjected to enteroanastomosis or enterostomy. In most cases it was nearly in possible to excise the disordered portions. As for the effect of surgical procedures on symptoms, cases of melena or fistulation were all subjected to colostomy; the majority of these cases showed improvement in symptoms. Moreover, a high improvement ratio was obtained in cases of ileus which were subjected to enterectomy and enteroanastomosis. Cases of free perforation showed high improvement ratio irrespective of the surgical procedure given. As for postoperative complications, one case of free perforation at the ileum showed anastomotic leakage after partial resection. For cases suffering from late-phase intestinal tract disorders induced by irradiation, immediate resection of the disordered intestinal tract and anastomosis are ideal. However, conservative operations must be considered, based on the focal condition. (author).

The recently introduced new nosological category, Gastro Intestinal Stromal Tumors, brought the Authors to a revision of their series and to a critical analysis of surgical behaviour for the treatment of that pathology. A series of 23 cases of GIST, observed between 1977 and 1999 has been taken into account. In the earlier cases, histopathological classification has been reviewed according to the most used criterions in international scientific literature. 17 of 23 observed tumors were located on the stomach, 4 on the duodenum and 2 on the jejunum. 20 of these cases derived from muscular tissue and 3 cases derived both from muscular and neural tissues. In 7 cases (30%) tumors were accidentally discovered during surgical intervention or diagnostic procedures for other causes. Surgical treatment was performed in all cases and consisted in 6 gastric resections, 14 gastric free-margin excisions, 2 duodenal resections and 1 jejunal resection. The follow-up (performed on 18 patients, with a minimum of 1 year, a maximum of 17 years and a median of 6 years) showed 2 deaths (11%) due to oncological causes, while 2 of the patients (11%) died for other causes. The only treatment for that group of tumors is, at the moment, surgery. Although that kind of neoplasms has mainly non-aggressive biological behaviour, a radical resection must be performed, due to the absence of macroscopic criterions to help distinguishing, during surgical intervention, aggressive tumors from non-aggressive ones.
Full Text Available Paradigms have started to shift in the orthodontic world since the introduction of mini-implants in the anchorage armamentarium. Various forms of skeletal anchorage, including miniscrews and miniplates, have been reported in the literature. Recently, great emphasis has been placed on the miniscrew type of temporary anchorage device (TAD. These devices are small, are implanted with a relatively simple surgical procedure, and increase the potential for better orthodontic results. Therefore, miniscrews not only free orthodontists from anchorage-demanding cases, but they also enable clinicians to have good control over tooth movement in 3 dimensions. The miniplate type also produces significant improvements in treatment outcomes and has widened the spectrum of orthodontics. The purpose of this paper is to update clinicians on the current concepts and versatile uses and clinical applications of skeletal anchorage in orthodontics.

Adult orthodontics poses a challenge for practitioners as it involves unique biomechanical considerations due to biologic age related changes and lack of skeletal growth potential. Dental risks in adult orthodontics include, amongst others, root resorption and periodontal complications. As modern life calls for quick and efficient orthodontic treatments, a novel orthodontic modality was developed utilizing adjunctive periodontal surgery that includes bone corticotomy combined with bone augmentation. This multidisciplinary team approach: Periodontally Accelerated Osteogenic Orthodontics (PAOO) or Wilckodontics seems to be promising not only for reducing orthodontic treatment duration, but also for biological aspects during and after orthodontic treatment. PAOO enhances bone remodeling and augmentation, accelerates tooth movement and significantly reduces the duration of treatment. The presented cases manifest the biologic benefit of profound enlargement in the envelope of motion reducing the need for extraction and eliminating the need for aggressive intervention of surgically-assisted rapid maxillary expansion. PAOO serves as a reasonable and safe option for the growing demand of shortened treatment duration of adult teeth movement in three dimensions. Further research is recommended for an in depth evaluation of the long-term stability claimed to be advantageous in this modality.
Full Text Available Introduction: Molar incisor hypomineralization (MIH is a developmental condition resulting in defects in the enamel characterized by demarcated opacities mainly affecting first permanent molars and occasionally permanent incisors in 1 of every 6 children worldwide. Affected molars have greater susceptibility to post eruptive breakdown, extensive caries and, in severe cases, are difficult to restore. When the MIH-affected molar presents severe crown destruction, it is necessary to perform an intermediate restoration to preserve the remaining dental structure in order to maintain occlusion, proper hygiene and periodontal health. The case of an 11-year-old patient with severe MIH is reported. The patient had extensive crown destruction by caries in tooth 1.6 without clinical or radiographic signs of pulp pathology. After an initial preventive intervention, enamel without dentin support and carious dentin were removed from tooth 1.6. Subsequently, crown restoration was performed with resin-modified glass ionomer, followed by the cementation of an orthodontic band. After 18 months of follow-up, the patient reported no pain or discomfort. The restoration was preserved intact, maintaining occlusal functionality, pulp and gingival health. Conclusion: The interim treatment, cementing an orthodontic band over a tooth restored with glass ionomer seems to favor retention and compressive strength, keeping the MIH-affected molar asymptomatic for at least 18 months. Further studies evaluating this treatment option in similar clinical situations are recommended.

The aim of this paper is to propose a single stage global treatment of endodontic, periapical and periodontal lesions in a lateral maxillary incisor with dens invaginatus. A 24 year-old woman presenting a lateral maxillary incisor with dens invaginatus in association with periapica1 and periodontal lesions underwent simultaneous surgical, endodontic and periodontal regenerative procedures. At 2, 6, 12, 18 months follow-up the radiographic healing appeared to be improved and the periapical lesion healed completely 1 year after surgical intervention. Surgery in association with endodontic and periodontal procedures represents the treatment of choice to maximize long term prognosis in cases of dens invaginatus with chronic periapical and periodontal lesions.
Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

In this case report, we describe the successful long-term treatment of a patient with dental agenesis. The initial treatment plan included an orthodontic phase to provide adequate space for replacing missing lateral incisors with implants. However, because of some complications encountered after 2 years of orthodontic treatment, a revised treatment plan was considered to achieve functional and esthetic goals. The patient was completely satisfied 5 years after being treated with two 2-unit cantilevered resin-bonded fixed partial dentures supported by the cuspids. This conservative treatment plan was cost-effective without having any significant biological cost.

Full Text Available Despite increasing demand for lingual orthodontics, the technique is not very popular among the orthodontists in general. Lingual orthodontics differs from the conventional labial technique in all aspects. Lack of comprehensive training in this field is a major obstacle in popularizing this science of invisible orthodontics. At present, short-term courses and part-time degree programs are the means to learn this technique and the demand for more comprehensive lingual orthodontic education is on a rise among orthodontists. Lingual orthodontics as a super specialty discipline with full-time residency program can be a step forward. This will groom orthodontists to acquire the finest skills to finish lingual cases but also help to the science to grow with dedicated research work.

Full Text Available Objectives. Distal biceps tendon rupture affects the functional upperextremity movement, impairing supination and flexion strength. According to age, profession and additional risks treatment might be nonoperative or surgical. Methods. We describe the case of a 43 years old male patient who sustained an injury to his right distal biceps and was diagnosed with acute right distal biceps rupture. Surgical treatment was decided and biceps tendon was reinserted to the radius tuberosity using a combination of a cortical button fixation associated with an interference screw. Results. Postoperative functional result was favorable with no complications and with no movement limitation after one month. Conclusions. When possible, distal biceps tendon repair should be realized surgically because this permits restoring of the muscle strength to near normal levels with no loss of motion. Nerve complications are common; therefore the surgery should be realized by experienced upper extremity surgeons.

In dental practice, low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) are mainly used for dental surgery and biostimulation therapy. Within the Orthodontic specialty, while LLLT has been widely used to treat pain associated with orthodontic movement, accelerate bone regeneration after rapid maxillary expansion, and enhance orthodontic tooth movement, HILT, in turn, has been seen as an alternative for addressing soft tissue complications associated to orthodontic treatment. The aim of this study is to discuss HILT applications in orthodontic treatment. This study describes the use of HILT in surgical treatments such as gingivectomy, ulotomy, ulectomy, fiberotomy, labial and lingual frenectomies, as well as hard tissue and other dental restorative materials applications. Despite the many applications for lasers in Orthodontics, they are still underused by Brazilian practitioners. However, it is quite likely that this demand will increase over the next years - following the trend in the USA, where laser therapies are more widely used.
Full Text Available In the modern day dental practice, synergy is fundamental. This synergistic effect must exist among various disciplines of dentistry for proper diagnosis, treatment planning, sequencing and execution of treatment in complex and challenging dental situations. Such collaborative effect between an orthodontist and a periodontist is essential as both works with same element, the tooth as crown-root unit with its supporting tissues. The orthodontic treatment is carried out through the medium of periodontium, so a healthy tooth supporting system is an essential prerequisite. Every potential candidate for orthodontic treatment should undergo a thorough periodontal examination. Any lousily diagnosed or conducted orthodontic treatment could be a facilitator of periodontal inflammatory or infectious process especially when the patient's oral hygiene is explicitly deficient. This case report demonstrates a challenging situation to a periodontist where patient had completed her orthodontic treatment but ended up with severe periodontal disease. The patient was thoroughly examined and a comprehensive treatment was planned and executed. Regenerative surgical procedures were done using platelet rich fibrin and hydroxyapitatite bone graft. Patient was followed up for 2 years. As sequelae of surgical procedures, patient had developed black triangles in the anterior region. The patient was unwilling for further perioplastic surgical procedures and further orthodontic treatment, so a gingival prosthesis using valplast was fabricated addressing her esthetic concerns.

Presurgical orthodontic treatment before secondary alveolar bone grafting (SABG) is widely performed for cleft lip/palate patients. However, no randomized controlled trial has been published comparing SABG outcomes in patients with, and without, presurgical orthodontic treatment. This randomized, prospective, single-blinded trial was conducted between January 2012 and April 2015 to compare ABG volumes 6 months postoperatively between patients with and without presurgical orthodontic treatment. Twenty-four patients were enrolled and randomized and 22 patients completed follow-up. Patients who had presurgical orthodontics before SABG had significantly improved inclination (p < 0.001) and rotation (p < 0.001) of the central incisor adjacent to the defect, significantly improved ABG fill volume (0.81 ± 0.26 cm3 at 6 months compared to 0.59 ± 0.22 cm3 p < 0.05) and less residual alveolar bone defect (0.31 ± 0.08 cm3 at 6 months compared to s 0.55 ± 0.14 cm3 p < 0.001) compared to patients who did not have presurgical orthodontic treatment. In conclusion, orthodontic treatment combined with SABG results in superior bone volume when compared with conventional SABG alone.

ígida pode ser utilizada com bastante propriedade no tratamento ortodôntico qunado for requerida uma ancoragem máxima.It is needless to say that anchorage control is necessary to a successful orthodontic treatment. Without it, it would be impossible to obtain an ideal occlusion through orthodontic mechanics in the majority of cases. The utilization of rigid devices, originated from face traumatology and implant dentistry principles, to obtain rigid anchorage in orthodontics revolutionized the way of treating cases with an unsatisfactory prognosis. Specially in cases where a lot of anchorage is needed and it is difficult or impossible to get it. The objective of this article was to revise the literature related to the use of mini-screw implant systems, to report a case where it was utilized and to discuss some aspects related to the usage of rigid anchorage orthodontics. The rigid anchorage was used in a 39 year old female patient, who had the upper left molars with a relevant extrusion due to the absence of the lower left molars. Fixed appliances were placed on the upper arch with a TPA connecting the second bicuspids. The TPA was used to anchor the intrusion of the upper left molars. A quad-helix appliance was used to correct the upper right third molar crossbite. Since the orthodontic intrusion with only dental anchorage did not have a satisfactory result, an "L" shaped titanium plate was placed on the maxilla, at the apical region of the upper first and second left molars, with the purpose of obtaining a rigid orthodontic anchorage to intrude them. Elastics were used during five months with intrusive force,the obtained intrusion was 6 millimeters. After the removal of the appliance, upper and lower dental bleaching was made and final prosthesis were placed over the implants. Through the literature reviewed and the case reported, it can be concluded that rigid anchorage can be indicated in orthodontic treatments where there is lack of anchorage or the need of an absolute

Three cases of symptomatic extradural arachnoid cyst were treated by surgery. Total excision of the cyst followed by tight closure of the fistula by suture was achieved in all 3 cases. Surgery improved the neurological deficits but urinary incontinence persisted in all three patients. Obliteration of the fistula is considered to be important at surgery from the etiological perspective of the cyst. There are many surgical options, but surgical removal of the cyst and obliteration of the communication usually leads to prompt improvement in neurological deficits. Instability, malalignment, and worsening scoliosis are well-recognized postoperative complications of excessive laminotomy, but the exposure should be wide enough to cover the cyst completely at the operation. Wide exposure of the entire cyst is preferable to avoid missing the fistula and to identify any adhesions or fistula between the cyst and the dura. Identification of the fistula location based on preoperative imaging studies is also important.

Sacroiliac syndrome is characterized by buttock and lower limb pain that is associated with decreased mobility and tenderness of the sacroiliac joints. It can occur concomitantly with disorders of the lumbar spine and may go unrecognized until these other conditions are successfully treated. It may sometimes be associated with post-surgical immobilization of the spine and pelvis. A case is presented illustrating successful treatment by chiropractic manipulation.

Gossypiboma or retained surgical sponge is an infrequently encountered surgical complication, more so in the head and neck region. A literature search did not reveal a previously reported case of retained or concealed surgical sponge after microscopic ear surgery. We present a unique and previously unreported case of a 25-year-old male who presented with a cystic swelling in the right supra-aural region 5 months post-modified radical mastoidectomy of the right ear. Surgical excision of the swelling revealed a retained surgical sponge. We emphasise the importance of counting surgical sponges after every surgical step to minimise the incidence of such retained surgical items.

Generalized gingival enlargement is characterized by massive and exuberant gingival overgrowth that poses social, aesthetic, phonetic and functional problems for the patient. Therefore, it requires meticulous management. Objective: To describe the surgical management of generalized gingival enlargement by electrosurgical excision of patients presenting to a tertiary care centre. Study Design: Case series. Materials and Methods: The study was conducted at the Department of Oral and Maxillofacial Surgery, de'Montmorency College of Dentistry, Lahore, from January 2010 to December 2012. A total of sixteen patients were operated by using electrosurgical approach under general anaesthesia for surgical excision of generalized gingival enlargement. Results: All of the sixteen patients, 11 males and 5 females, showed excellent healing postoperatively without any recurrent gingival overgrowth. Discussion: To the best of our knowledge, the current study presents the largest case series of generalized gingival enlargement. Most of these cases were with massive disease due to lack of information of the study population about their disease, delay in referral by the general dental practitioners, painless and innocent nature of the problem. Early referral of such patients to tertiary care centers can prevent the patients from social and psychological embarrassment. Conclusion: Electrosurgical excision is an excellent surgical technique for management of generalized gingival enlargement. Moreover, cross comparative studies are required to establish some diagnostic and therapeutic standards for such patients. (author)

Full Text Available Perianal fistula, usually has a criptoglandular etiology, developing from a perianal abscess and communicating the anal mucosa with the perianal skin. The aim of this paper is to study retrospectively 241 cases of perianal fistula (172 men and 69 women; 2,5:1 aging from 7 and 80 years old (average: 37,4 years, operated on at the Hospital da Clínicas - UFMG, from 1977 to 1996. The surgical techniques and post-operative outcome have been analysed. Perianal abscesses with spontaneous drainage were the predominant etiology (132 patients; 54,8%. Eighty percent were submitted to fistulectomy as the first surgical treatment. Among early complications (78; 32,4%, local pain was the most frequent (60; 24,9%. Among the late complications (136; 56,4% fistula recurrence (101; 41,9% was the most frequent. There were 141 reoperations in 80 patients. Fistulectomy was the predominant surgical technique employed for the treatment (101; 71,6%. The average hospitalization time was 6,3 days until 1990 and 1,5 day from 1991 to 1996, after the advent of day-surgery beds in HC-UFMG. The surgical treatment of perianal fístula has a significant rate of post-operative complications and a high recurrence rate, in spite of the short stay in hospital.
Full Text Available Introduction: Rhinophyma is a tumour-like enlargement of the skin of the nose, affecting dorsum nasi and the apex. While the aetiology is unknown, dermatosis rosacea can be indicated as one of the main causes. Rhinophyma is characterized by reddish, swollen bumpy surface of the nose, overgrowing of scar-like tissue and augmentation of the sebaceous glands. Epidemiologically, rhinophyma affects mainly men between the ages of 50 and 70. Purpose of the study: To present an overview of the disease based on our personal experience with the condition and the associated surgical treatment. Materials and methods: Our findings are based on the cases of four patients over a period of two years, diagnosed with the condition rhinophyma, who underwent surgical treatment in “Saint Marina” hospital. The excision was made using the “Coblator II system”. Results: Due to unresponsiveness to conventional treatment, surgical removal of the rhinophyma was necessary. Conclusion: Rhinophyma is a rare condition, causing discomfort to the patient and deforming the nose. Surgical intervention shows most effective results in the treatment of this disease.

Demand for shorter treatment time is common in orthodontic patients. Periodontally Accelerated Osteogenic Orthodontics (PAOO) is a somewhat new surgical procedure which allows faster tooth movement via combining orthodontic forces with corticotomy and grafting of alveolar bone plates. Leukocyte and Platelet-Rich Fibrin (L-PRF) possess hard- and soft-tissue healing properties. Further, evidence of pain-inhibitory and anti-inflammatory potential is growing. Therefore, this study explores the feasibility, intra- and post-operative effects of using L-PRF in PAOO in terms of post-operative pain, inflammation, infection and post-orthodontic stability. A pilot prospective observational study involving a cohort of 11 patients was carried out. A Wilcko's modified PAOO technique with L-PRF (incorporated into the graft and as covering membrane) was performed with informed consent. Post-surgical pain, inflammation and infection were recorded for 10 days post-operatively, while the overall orthodontic treatment and post-treatment stability were followed up to 2 years. Accelerated wound healing with no signs of infection or adverse reactions was evident. Post-surgical pain was either "mild" (45.5%) or "moderate" (54.5%). Immediate post-surgical inflammation was either "mild" (89.9%) or "moderate" (9.1%). Resolution began on day 4 where most patients experienced either "mild" or no inflammation (72.7% and 9.1%, respectively). Complete resolution was achieved in all patients by day 8. The average orthodontic treatment time was 9.3 months. All cases were deemed stable for 2 years. L-PRF is simple and safe to use in PAOO. Combination with traditional bone grafts potentially accelerates wound healing and reduces post-surgical pain, inflammation, infection without interfering with tooth movement and/or post-orthodontic stability, over a 2 years period; thus alleviating the need for analgesics and anti-inflammatory medications.

Study Design Cross-sectional survey using a national database. Setting Academic otolaryngology residency programs. Subjects and Methods Review of otolaryngology resident national data reports from the Accreditation Council for Graduate Medical Education (ACGME) resident case log system performed from 2004 to 2015. Minimum, mean, standard deviation, and maximum values for total number of supervisor and resident surgeon cases and for specific surgical procedures were compared. Results The mean total number of resident surgeon cases for residents graduating from 2011 to 2015 ranged from 1833.3 ± 484 in 2011 to 2072.3 ± 548 in 2014. The minimum total number of cases ranged from 826 in 2014 to 1004 in 2015. The maximum total number of cases increased from 3545 in 2011 to 4580 in 2015. Multiple key indicator procedures had less than the required minimum reported in 2015. Conclusion Despite the ACGME instituting required minimum numbers for key indicator procedures, residents have graduated without meeting these minimums. Furthermore, there continues to be large variations in the minimum, mean, and maximum numbers for many procedures. Variation among resident case numbers is likely multifactorial. Ensuring proper instruction on coding and case role as well as emphasizing frequent logging by residents will ensure programs have the most accurate data to evaluate their case volume.

Full Text Available This case report demonstrates an orthodontic method that offers short treatment time and the ability to simultaneously reshape and increase the buccolingual thickness of the supporting alveolar bone. A 23-year-old female with Angle′s Class I moderately to severely crowded malocclusion with periodontal pocket with 31 and reduced thickness of the buccal cortical plate of lower anteriors, requested shortened orthodontic treatment time. This surgery technique included buccal full-thickness flaps, selective partial decortication of the cortical plates, concomitant bone grafting/augmentation, and primary flap closure. Following the surgery, orthodontic adjustments were made approximately every 2 weeks. From bracketing to debracketing, the case was completed in approximately 7 months and 3 weeks. Posttreatment evaluation of patient revealed good results. Preexisting thin labial bony cortical plate with lower anteriors was covered. This finding suggests credence to the incorporation of the bone augmentation procedure into the corticotomy surgery because this made it possible to complete the orthodontic treatment with a more intact periodontium. The rapid expansive tooth movements with no significant apical root resorption may be attributed to the osteoclastic or catabolic phase of the regional acceleratory phenomenon.

Calcaneal fractures are infrequent but, more often, serious. We report a series of 29 cases of calcaneal fractures surgically treated in the Orthopaedics and Traumatology in the University Hospital (CHU) Hassan II of Fez. This retrospective study aims to present the principles and to evaluate the results of surgical treatment for articular fractures of the calcaneus, in comparison with conservative treatment. Our study included 21 men and 8 women, the average age was 21-61 years. Etiology was dominated by road traffic accidents as wel as by falls from a high place. The evaluation of the lesions was based on the classification of Duparc. The treatment was based on open reduction associated with Y-plate osteosynthesis or one-third tubular plate osteosynthesis using triangulation. Clinical results were evaluated on the basis of kitaoka score, with an average follow-up period of 24 months. 86% of patients have had good medium-term results.

Ankylosis is the abnormal adhesion of alveolar bone to dentin or cementum and commonly seen after traumatic dental injuries. Treatment of impacted and ankylosed teeth solely by orthodontics alignment may be challenging. Consequently, several treatment alternatives have been proposed...... for the management of ankylosed teeth involving extraction, surgical luxation, and osteotomy followed by dentoalveolar distraction or conventional orthodontic treatment. This case report describes a 55-year-old female who was referred by her orthodontist due to an impacted and ankylosed maxillary upper left canine...

Full Text Available Corticotomy facilitated orthodontics has been practising for longer periods, but a novel approach of a periapical incision to make horizontal cuts 5 mm above the apex of the maxillary anteriors along with vertical cuts requires a detailed investigation. The purpose of this study was to assess the outcome of skeletal cases with spacing in the anteriors using a novel method of modified surgical approach utilizing the corticotomy facilitated orthodontics. Patients for this study were randomly selected from a very intensive screening in the Department of Orthodontics, Saveetha Dental College and Hospital, Chennai, out of which seven patients were selected for this procedure. The patients were subjected for corticotomy procedure under local anesthesia after the leveling and aligning stage (0.019" × 0.025" stainless steel wire, and the retraction was continued still the space was closed. AutoCAD and palatal rugae assessment programs were used to assess the orthodontic tooth movement. The results of the study demonstrated that when compared to conventional orthodontics alone, the corticotomy facilitated approach produced faster tooth movements in all the seven patients reducing the overall treatment time by 60%. The use of this modified technique of labial, palatal and apical cuts could be beneficial for adult patients with difficult surgical access from the lingual side.
Full Text Available Profunda femoris artery aneurysm (PFAA is an extremely rare entity, with most cases being asymptomatic, which makes obtaining an early diagnosis difficult. We herein report a case series of PFAA, in which more than half of the PFAAs, which presented with no clinical symptoms, were discovered incidentally. All PFAAs were treated surgically with aneurysmectomy with or without vascular reconstruction. In cases involving a patent superficial femoral artery (SFA, graft replacement of the profunda femoris artery (PFA is not mandatory; however, preserving the blood flow of the PFA is necessary to maintain lower extremity perfusion in patients with occlusion of the SFA. Therefore, the treatment of PFAAs should include appropriate management of both the aneurysmectomy and graft replacement, if possible.
Full Text Available Our case-based review focuses on limb salvage through operative management of Charcot neuroarthropathy of the diabetic foot. We describe a case, when a below-knee amputation was considered in a patient with chronic Charcot foot with a rocker-bottom deformity and chronic plantar ulceration. Conservative treatment failed. Targeted antibiotic therapy and operative management (Tendo-Achilles lengthening, resectional arthrodesis of Lisfranc and midtarsal joints, fixation with large-diameter axial screws, and plaster cast were performed. On the basis of this case, we discuss options and drawbacks of surgical management. Our approach led to healing of the ulcer and correction of the deformity. Two years after surgery, we observed a significant improvement in patient’s quality of life. Advanced diagnostic and imaging techniques, a better understanding of the biomechanics and biology of Charcot neuroarthropathy, and suitable osteosynthetic material enables diabetic limb salvage.

The use of surgical drains in abdominal surgery is still today controversial. While accepting their role in certain circumstances, their systematic use advocated by other schools, is not fully accepted. We present a case of secondary blind drilling drainage tube perineum following an abdominoperineal amputation of the rectum that forced a surgical repair in a neoplastic patient This is a patient who underwent abdomino perineal resection for rectal neoplasia. It was decided to leave a silicone-type drain tube for perineum and in late postoperative he presented cecum perforation due to traumatic introduction thereof into the cecal light, which forced his reoperation and surgical repair. There is a tendency to use less and less drains in abdominal surgery, although there are certain occasions when it becomes inevitable. On the other hand it entails morbidity associated with its use that significantly complicates and delays the recovery of the patient. It is accepted that is not useful to prevent the occurrence of fistulas, although it contributes to its early detection. The cecal perforation due to drain is a rare complication which must always be taken into account, and that perhaps could be avoided by using soft and less rigid drains. Copyright © 2015.

Full Text Available These days, as a consequence of the improvement in technology and increase in the use of motor vehicles, spine injuries have become common. Spine traumas, which often occur after motor vehicle accidents, are observed mostly in cervical regions, particularly in the subaxial cervical region, which is also known as the subcervical region, and neurological damage occurs in 70% of the patients. Despite still being controversial, the common ranging for neurological evaluation is the American Spinal Injury Association ranging, which includes the motor and sensory loss and accordingly, the impairment rate. In subaxial cervical traumas, acute neurological deterioration is an indication and therefore requires urgent surgical treatment. The choice of anterior or posterior approach substantially depends on the traumatization mechanism, affected tissues, and neurological deterioration occurring after. The state of patient and instability are the most two important factors affecting the treatment decision. Although the anterior approach is accepted as a routinely available and easily applicable surgical technique, it lacks in the burst fractures involving the three colons, which shows a stabilization disorder. The anterior plate screw technique and posterior lateral mass screw application applied in our clinic are reviewed in literature and are discussed in two cases. Although the best clinical results are achieved in cases where only anterior surgery is performed and in cases where instability is excessive, in unstable compression and blow-out fractures, even if neurological deficit and three colon involvement are not observed in the patient, the requirement of posterior fusion is observed.

This case report documents the first use of particulate autogenous bone graft with the corticotomy-assisted rapid orthodontic procedure known as periodontally accelerated osteogenic orthodontics (PAOO). A 41-year-old man, with class II, division 2 crowded occlusion, was treated with the PAOO procedure. Buccal mucoperiosteal flaps were reflected, and selected vertical and horizontal corticotomy was performed around the roots in both the maxillary and mandibular arches. Particulate bone graft was harvested from the rami and exostosis for alveolar ridge augmentation. Orthodontic movement was initiated immediately after the surgical intervention and adjusted every 2 weeks. Eight months after corticotomy surgery, total active orthodontic treatment was completed. No detrimental periodontal effects or root resorption were observed. The alveolar ridges of both the maxilla and mandible maintained the original thickness and configuration despite facial tipping of the incisors. It was concluded that PAOO is an effective treatment approach in adults to decrease treatment time and reduce the risk of root resorption. Selected corticotomy limited to the buccal and labial aspects also significantly reduces treatment time. More clinical studies with additional patients and long-term follow-up are needed to determine the optimal amount of autogenous bone graft.

The purpose of this long-term follow-up study was twofold-firstly, to assess prevalence of relapse after treatment of deep bite malocclusion and secondly, to identify risk factors that predispose patients with deep bite malocclusion to relapse. Sixty-one former patients with overbite more than 50% incisor overlap before treatment were successfully recalled. Clinical data, morphometrical measurements on plaster casts before treatment, after treatment and at long-term follow-up, as well as cephalometric measurements before and after treatment were collected. The median follow-up period was 11.9 years. Patients were treated by various treatment modalities, and the majority of patients received at least a lower fixed retainer and an upper removable bite plate during retention. Relapse was defined as increase in incisor overlap from below 50% after treatment to equal or more than 50% incisor overlap at long-term follow-up. Ten per cent of the patients showed relapse to equal or larger than 50% incisor overlap, and their amount of overbite increase was low. Among all cases with deep bite at follow-up, gingival contact and palatal impingement were more prevalent in partially corrected noncompliant cases than in relapse cases. In this sample, prevalence and amount of relapse were too low to identify risk factors of relapse. © The Author 2012.

Twenty-one surgical cases out of 31 thoracic were discussed in comparison with computed tomography (CT), conventional chest x-ray film and findings on operation. CT was found useful in several respects. Azygo-esophageal recess (AER), which is normally seen between the vertebra and the carina, disappeared in the cases with enlarged lymph nodes around the carina. But AER was kept in the same fashion as normal in all cases free from those nodes enlargement. A low density line between tumor shadow and the mediastinum was good information to know preoperatively whether it was resectable or not. There were no resected cases of which CT films failed to show the border of the tumor shadow. Though CT is often used to evaluate mediastinal tumor, because of its horizontal cross picture, it is seldom diagnostic. Enlarged thoracic aorta and a minimum amount of calcium on its wall, and fat tissue in the retrosternal space which conventional x-ray films failed to reveal in both cases were definitive signs of aneurysm of thoracic aorta and foramen of Morgagni hernia respectively. CT is also able to demonstrate a small pulmonary nodules in the fields in much more early stage than conventional x-ray film is, which must be good adjunct to detect lung cancer. (author)

occurrence. OBJECTIVE: this article reports two cases of simple bone cyst found in routine radiographic examination of orthodontic treated patients. CASE REPORT AND DISCUSSION: in both cases, the clinical diagnosis was confirmed by biopsy and histological examination. The patients underwent surgical exploration and a radiographic follow up showed evidence of local healing. This study discuss if there is a relationship between the orthodontic trauma and the occurrence of simple bone cyst in these patients, or if it represents an incidental finding, since they are most frequently submitted to radiographic examination.

The acute abdomen (AA) still remains a challenging situation for surgeons. New pathological conditions have been imposed to our attention in this field in recent years. The definition of abdominal compartmental syndrome (ACS) in surgical practice and the introduction of new biological matrices, with the concepts of tension-free (TS) repair of incisional hernias, prompted us to set up new therapeutic strategies for the treatment of patients with AA. Thus we reviewed the cases of AA that we observed in recent years in which we performed a laparostomy in order to prevent or to treat an ACS. They are all cases of acute abdomen (AA), but from different origin, including chronic diseases, as in the course of inflammatory bowel disease (IBD), and acute pancreatitis. In all the cases, the open abdominal cavity was covered with a polyethylene sheet. The edges of the wound were sutured to the plastic sheet, and a traction exerted by a device that causes a negative pressure was added. This method was adopted in several cases without randomization, and resulted in excellent patient's outcomes. Abdominal compartmental syndrome, Acute abdomen, Laparostomy.

The aim of this study was to examine the esthetic parameters that are applied, more or less unconsciously, in deciding for or against orthodontic space closure in the case of aplasia or traumatic loss of lateral incisors. The width-height index for teeth 13 to 23 was measured on 200 dental students. The VITA Easyshade system was used to determine the components of the tooth color (L, C, h) and to identify differences between each tooth. Eight investigators subjectively assessed digital photographs of the subjects, opting for or against space closure. The Spearman correlation coefficients were calculated for the parameters measured. A comparison of the parameters showed that not one factor alone was responsible for the decision for or against space closure for esthetic reasons. Orthodontists were more likely to favor space closure when the canine was slightly wider and had a less pointed shape and the differences were very small between canine and central incisor in terms of hue, chroma, and lightness. We observed that the subjective decision on the esthetic aspects of space closure correlates closely with the objective criteria.

Nickel hypersensitivity is a common problem, especially among young females, with a prevalence of 5 to 10%, increasing to 30%. In comparison with the oral mucosa, skin is more sensitive to an allergic reaction. The oral mucosa is less sensitive to nickel due to the difference in anatomical structure and the presence of pellicle. Nickel is used in many orthodontic appliances. Due to corrosion nickel ions can be released into the oral cavity. The extent of the corrosion of the appliance depends on the pH, the composition of saliva and plaque, temperature and mechanical loading. In spite of the relatively high amount of nickel processed in orthodontic appliances nickel allergies are rare. In cases of nickel-hypersensitivity, nickel-free appliances should be used.

Periodontally accelerated osteogenic orthodontic procedure has become useful adjunct to reduce orthodontic treatment time as compared with conventional orthodontics. This case demonstrates the use of Piezosurgery ® to facilitate rapid tooth movement with relatively shorter treatment time. A 23-year-old male with Angles Class I malocclusion having spaced anterior teeth and protrusion requested orthodontic treatment with reduced time period. Before surgery, presurgical orthodontic treatment was done to do initial alignment of the teeth. This was followed by piezosurgical corticotomy and final space closure was achieved by active orthodontic tooth movement. The total treatment time required to complete the orthodontic treatment was 5 months. 1-year follow-up revealed no evidence of any adverse periodontal effects or relapse. Thus, Piezosurgery ® -assisted corticotomy may prove to be a noble and effective treatment approach to decrease the orthodontic treatment time.

To present a novel orthodontic approach for minimally invasive extraction of impacted mandibular third molars (M3s) close to the inferior alveolar nerve (IAN). Eight patients (8 M3s) requiring extraction of M3s were included in this study; there were 2 cases of horizontal impaction, 4 of mesioangular impaction, and 2 of vertical impaction. Cone-beam computed tomogram showed that the roots of impacted M3s in 2 cases interrupted the cortices of the mandibular canal, and those in the other 6 cases were very close to the IAN. Orthodontic treatment was performed in this study. The crowns of 5 impacted teeth were surgically exposed before the application of the orthodontic device, whereas bonding was performed directly to the occlusal surface of the other 3 M3s, which had partially erupted. The opposing maxillary M3s were removed in 3 cases. One-step orthodontic extraction was applied to vertically impacted M3s and 2-step treatment was applied to horizontally or mesioangularly impacted M3s. Success was defined as the separation of the impacted tooth from the IAN as visualized on cone-beam computed tomogram. After orthodontic treatment, all impacted M3s were extruded and separated from the IAN (mean, 6.6 months; range, 4 to 10 months), without any neurologic consequences. The average time of extraction was 5 minutes. In all 8 cases, new bone formation occurred distal to the adjacent second molar. This orthodontic technique may be a minimally invasive approach for the extraction of impacted M3s adjacent to the IAN, with a decreased risk of paresthesias and with osteoperiodontal advantages.

The purpose of this article is to report on the five-year follow-up of a case involving treatment of gingival recession with a subepithelial connective tissue graft prior to orthodontic tooth movement. Gingival recession has a global prevalence that varies from 3 to 100 percent depending on the population studied and the method of analysis. In addition, the frequency of recession seems to be positively correlated with age. Planned orthodontic tooth movement is not necessarily an etiological factor for gingival recession, so long as it does not move the tooth out of its alveolar process. When the tooth is shifted without adequate biomechanical control, bone dehiscence can develop, and the recession can occur as a consequence of the orthodontic treatment. A 19.6-year-old female patient was referred for orthodontic treatment due to severe anterior-inferior dental crowding and a mandibular right lateral incisor in linguoverson and 4.0 mm of gingival recession on the labial surface. Normal gingival architecture was restored with a subepithelial connective tissue graft used to cover the 4.0 mm defect, after which orthodontic treatment repositioned the malposed incisor into its correct occlusal alignment. Individualized torque was applied to the mandibular right central incisor during the orthodontic treatment. The patient was reevaluated five years after completion of the orthodontic treatment. At the five-year recall appointment, the patient exhibited normal tooth alignment and generalized normal gingival architecture; however, 2 mm of gingival recession was noted on the graft site. This case demonstrated that periodontal surgical correction of facial gingival recession with a subepithelial graft may be performed prior to initiating orthodontic treatment.

Conclusion: Based on result of this study, corticotomy can accelerates the rate of orthodontic tooth movement about two times faster than conventional orthodontics and it is significant in early stages after surgical porsedure. Therefore Buccal corticotomy is a useful adjunct technique for accelerating orthodontic tooth movement.

Oxidative stress is a pathologic event induced by a prevalence of oxidant agents on the antioxidant ones, with a consequent alteration of oxide-reducing balance. Freeradicals produce damages both in cellular and extra-cellular components; phospholipid membranes, proteins, mitochondrial and nuclear DNA, are the target of the oxidative stress, that can finally cause cellular death due to apoptosis. Orthodontic appliances such as brackets, wires, resins and soldering have some components that can be considered as potential allergen, carcinogenic, cytotoxic and gene mutation factors. The primary aim of this research is to evaluate oxidative stress in the saliva of patients treated with multibracket self-ligating vestibular orthodontic appliances; the secondary purpose is to investigate the influence of orthodontic multibracket therapy on oral hygiene and the consequent effect on oxidative stress. Salivary specimens has been collected in a sample of 23 patients were enrolled (12 Female, 11 Male) between 12 and 16 years of age (mean age 14.2). For each patient has been collected a salivary specimen at the following time points; before orthodontic bonding (T1), five weeks (T2) and ten weeks (T3) after orthodontic appliance bonding. Samples has been analysed with a photometer due to SAT Test (Salivary Antioxidant Test). Data obtained show a mean of 2971 mEq/l of anti-oxidant agents before orthodontic treatment, and after five weeks from the bonding the mean was decreased to 2909 mEq/l, instead at ten weeks was increased to 3332 mEq/l. Repeated measures ANOVA did not reveal statistically significant differences between the time points ( P = 0.1697). The study did not reveal any correlation between the level of dental hygiene and that of oxidative stress (Pearson Correlation Coefficient R = 0). Orthodontic treatment with multibrackets vestibular metallic appliance seems to be not able to affect oxidative stress during the first ten weeks of therapy.

The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy. The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal treatment. Dens invaginatus is a rare dental anomaly that can give rise to many complex anatomical forms. The complete removal of the diseased pulp tissue can be a challenge for clinicians due to the complexity of internal canal anatomy and may require either non-surgical endodontic therapy alone or that therapy may have to be combined with surgical endodontics to achieve an adequate sealing of the root canal system. A 22-year-old male presented for evaluation of a recurrent painless sinus tract in the attached gingiva adjacent to the maxillary right lateral incisor. The tooth responded negatively to vitality tests while the right central incisor responded normally. Clinically an anatomical malformation in the crown was detected in the form of an abnormal bulbous contour of the tooth in the palatal region above the cingulum. Radiograph evaluation confirmed the presence of dens invaginatus and a periapical radiolucent lesion. The patient received combined non-surgical and surgical endodontic therapy to achieve a favorable outcome. Complications presented by Type III dens invaginatus and acute periapical abscess necessitated the use of combined non-surgical and surgical endodontic therapy to attain a favorable seal of the root canal. The prognosis at a six-month post-treatment evaluation appeared to be good. Dens invaginatus requires an early diagnosis and treatment. It may result in radicular and periapical pathosis requiring a combined non-surgical and surgical endodontic approach to treatment.

Intramuscular myxoma (IM) is a benign, soft tissue neoplasm of mesenchymal origin. We report our experience with this tumour. This clinical study comprised 11 cases of IM that were operated on between March 2008 and June 2016. Tumour location and size, results of pre-operative radiological studies, preop-erative biopsies, pathology examinations, applied surgical method and post-operative complications were reported for all patients. In total, nine patients with 11 IMs with a mean age of 60.0 years were assessed. Mean follow-up was 39.2 months. Tumours were located in the right thigh (5 patients, 7 IM), left gluteal area (2 patients, 2 IM), right gluteal area (1 IM) and left thigh (1 IM) ranging from 2 × 1 cm to 10 × 17 cm Pre-operative radiological diagnoses were cystic lesion, abscess, bursitis, fibrosarcoma, fibroma, lipoma, malign mesenchymal tumour and IM. Pre-operative biopsy was performed for five cases. All tumours were removed via simple excision and were pathologically consistent with IM. No complication or recurrence was observed during the follow-up period. IM is a relatively rare benign tumour, the pre-operative diagnosis of which using radiological and clinical methods is quite difficult, creating pre-operative diagnostic confusion. It is generally diagnosed by microscopic examination. Simple excision with a small margin of surrounding tissue is considered to be sufficient for its treatment.
Full Text Available Catamenial pneumothorax (CP is a rare entity of spontaneous, recurring pneumothorax in females. Although it has been known to be associated with thoracic endometriosis, varying clinical course and the lack of consistent intraoperative findings have led to conflicting etiological theories. We herein discuss the etiology, clinical course, and surgical treatment of three patients with CP. Three females (aged 40 years, 28 years, and 34 years had recurrent right-sided spontaneous pneumothoraces that coincided with their menses. They had undergone video-assisted thoracoscopic surgery (VATS previously. Blueberry spots in the right diaphragm were detected in all three cases. Two patients had recurrence, postoperatively. The other patient, who received luteinizing hormone-releasing hormone analog therapy for an abdominal endometriosis in the perioperative period and postoperative chemical pleurodesis to prevent recurrence, has been free of recurrence for 15 months, postoperatively. However, pelvic endometriosis was detected in this patient only. Therefore, CP should be suspected in ovulating females with spontaneous pneumothorax, even in the absence of any symptoms associated with pelvic endometriosis. In addition, while performing VATS, careful inspection of the diaphragmatic surface is important. In complicated cases, hormonal suppression therapy and chemical pleurodesis might also be helpful adjunct modalities.

Surgeons, like other doctors, practice their profession within a framework of contractual liability defined by statute in 1936. This established that the doctor was subject to a contractual obligation to provide appropriate and diligent care. Care and technical acts should conform to those which would have been provided by a prudent doctor within the standards of knowledge and practice of his field; care which deviates from this standard would be considered medical error or fault. This standard of care is referred to as "sound professional conduct". However, while not calling this basic principle into question, civil jurisdictions have progressively held surgeons liable whenever injury has occurred following surgical acts, without considering whether care deviates from sound professional conduct. Since 2000, judges have begun to attribute a requirement for absolute safety of results in cases where the surgeon had injured an organ unrelated to the planned operation. However it seems that the rare judgments given on this topic in the last 2-3 years have become less frequent. The creation of a compensation regime for medical accidents, via the law dated March 4, 2002, has contributed to this evolution. It is to be hoped that the flaws described in this system do not encourage jurisdictions to reconsider previous case law decisions.

The syndrome X is a clinical disease characterised by anginous pain with the absence of significant and angiographically visible stenosis of the coronary tree. D. P. M., a 61-year-old woman suffering from biliary lithiasis, underwent cholecystectomy. During the immediate postoperative period, the patient showed difficulty in regaining consciousness and there were electrocardiographic signs of extensive anterior ischemia; prior to the operation only a 1st degree atrio-ventricular block and a positive history of occasional precordial pain had been reported. On the 2nd postoperative day the patient complained of violent retrosternal pain irradiated to the left shoulder. Given that the signs of ischemia had regressed, various instrumental tests were performed: echocardiogram, cycloergometric test, dipyridamole test, cold pressure test, Holter's dynamic ECG, all of which were within the normal; moreover, selective coronarography did not reveal significant stenosis of the coronary tree. The patient was therefore diagnosed as suffering from syndrome X. In the light of the present case, the authors conclusion may be summarised as follows: the diagnosis of syndrome X, which is by definition not easy, may sometimes become critical, as in the present case, since rapid intervention would have enabled prophylactic therapy to be performed to combat surgical stress.

This study seeks to establish the failure rate of sterilizations in the Profamilia pilot clinic in Bogota, and analyzes the chronology of the resulting pregnancies and their possible causes and the reactions of the women who became pregnant. 31,828 sterilizations were performed in the clinic between 1973 and 1980, 8% of them minilaparotomies. 272 of 290 pregnancies diagnosed after sterilization were method failures, the other 18 having begun before the operation. Almost 60% of the pregnancies occurred within 1 year of the operation, and all but 4% occurred within 4 years. The rate calculated on the basis of the 1st 12,000 sterilizations, 142 of which were followed by pregnancies due to method failure, was 1.18%, or 1 case per 85 operations. The average age of the women who became pregnant was 31.0 years, compared to the average of 33.4 years for all women undergoing sterilization. Possible reasons for the failures are discussed, including incomplete follow-up, defective materials, surgical skill, and the performance of operations by students. Analyses of 157 cases of reinterventions indicate that 27% of the failures resulted from human error and the rest from method imperfections including incomplete occlusion of the tube, recanalization, and refistulization. 7.35% of the pregnancies were ectopic. 33.8% of the women who became pregnant bore children, 11.7% had spontaneous abortions, and 54.5% sought induced abortions.

It is complicated to decide the treatment plan of hopeless anterior teeth in esthetic zone due to severe periodontitis, periodontal-endodontic combined lesion or teeth trauma. The optional treatment plan for this kind of teeth includes retention after periodontal treatment, extraction and implant treatment, extraction and prosthodontic treatment and so on. To make an appropriate treatment plan, patients' periodontal conditions, periodontal biotype, local anatomy, esthetic demand, economic condition and social psychological status should be comprehensively considered. A combine of periodontal, endodontic and orthodontic therapy may achieve a good treatment effect in hopeless anterior teeth with severe periodontal destruction, tooth extrusion and occlusal trauma. In this case, a 20-year-old female who presented with symptoms of bleeding on brushing and upper incisors loosening for 1 month came to the Department of Periodontology, Peking University School and Hospital of Stomatology. The clinical examinations revealed that the patient's right upper incisor had signs of mobility (III°), intrusion of 1-2 mm, and probing depth (PD) of 9-10 mm. The periapical radiograph showed that the alveolar bone of right upper incisor absorbed horizontally to the apex. And the patients showed Angle II° malocclusion with II° overbite in anterior teeth and maxillary protrusion. A diagnosis of aggressive periodontitis and Angle II° malocclusion was made. The treatment of this patient lasts for 5 years which include periodontal initial therapy, orthodontic therapy, guided tissue regeneration (GTR) of right upper incisor and supportive periodontal therapy and the clinical result is fine. A hopeless upper incisor was successfully retained and the longtime clinical condition was stable. The strategy of retention of hopeless upper anterior teeth, the relationship of periodontal treatment and orthodontic treatment, and the indications of periodontal and orthodontic combined therapy were

A 45-year-old woman presented with an anterior open-bite complaining chiefly of her unpleasant smile esthetics and masticatory and speech problems. Treatment included speech therapy initiated immediately after bonding. Lingual spurs were positioned on the mandibular incisors in order to help tongue rehabilitation. During the working phase, temporary anchorage devices (TADs) were used at the mandibular anterior segment to intrude the lower left premolars. A splint was used to ensure retention in the upper and lower arches; an enveloppe linguale nocturne (ELN) was provided. Non-surgical open-bite treatment could offer a valid alternative to orthognanthic surgery when cephalometric evaluation shows no vertical growth pattern; patient compliance is essential to prevent relapse.

Full Text Available Introduction: Pyoderma gangrenosum is a chronic neutrophilic dermatosis which can occur following trauma or surgery and can mimic infection. Surgical intervention can lead to progression of disease. Presentation of cases: This case series describes 3 cases of post-surgical pyoderma gangrenosum with delayed diagnosis from two large medical centers. Discussion: Epidemiology, pathogenesis, clinical and histopathologic presentation, and management of post-surgical pyoderma gangrenosum are discussed with a review of the literature. Conclusion: Post-surgical pyoderma gangrenosum (PSPG can mimic ulcerative disorders including bacterial infection. The diagnosis should be suspected in post-operative wounds with negative bacterial cultures which progress despite broad-spectrum antibiotics and surgical debridement. Recognizing the clinical features of PSPG is fundamental to prevent severe destruction and deformity. Keywords: Post-surgical, Pyoderma gangrenosum, Necrotizing fasciitis, Case report
Full Text Available Special needs individuals are children or adults pre‐ vented by a physical or mental condition permitting their full participation to the normal range of activities of their age groups. They usually exhibit high orthodontic treat‐ ment needs because of an increased prevalence and seve‐ rity of malocclusions. These conditions often require a coordinated craniofacial orthodontic and surgical treat‐ ment in a team setting, to achieve optimal outcome. Ort‐ hodontic treatments for patients born with facial differences tend to be more complex than ordinary ortho‐ dontics. This multidisciplinary treatment often starts from birth and extends up to the late teen years. The young patient may require treatment by multiple specialists, including a craniofacial surgeon, pediatrician, geneticist, neurosurgeon, ENT, speech and language therapist, pedi‐ atric dentist, oral surgeon and prosthodontist. The objec‐ tive of this paper is to summarize protocols of orthodontic treatment and to present various orthodontic management protocols regarding the children with special needs.

A case is presented of a 14-year-old female undergoing orthodontic fixed appliance treatment who presented with right facial swelling in the parotid region. An initial diagnosis of acute infective parotitis was made by her primary care clinician. However, after clinical examination and ultrasonographic imaging, a diagnosis of salivary stasis secondary to inflammatory occlusion of Stensen's ductal orifice was made. The ductal orifice had been traumatized by the adjacent orthodontic appliance. This has not been described before in the literature. The differential diagnosis of parotid enlargement in children is discussed.

Aim: To investigate radiological and clinical characteristics of pathologically proven cases of intrathymic cysts. Materials and methods: The study population consisted of 18 patients (five males, 13 females; median age 56 years) with pathologically confirmed intrathymic cysts who underwent thymectomy and had preoperative chest computed tomography (CT) available for review. The patient demographics, clinical presentation, and preoperative radiological diagnoses were reviewed. CT images were evaluated for shape, contour, location of the cysts and the presence of adjacent thymic tissue, mass effect, calcifications, and septa. The size and CT attenuations of the cysts were measured. Results: The most common CT features of intrathymic cysts included oval shape (9/18; 50%), smooth contour (12/18; 67%), midline location (11/18; 61%), the absence of visible adjacent thymic tissue (12/18; 67%), and the absence of calcification (16/18; 89%). The mean longest diameter and the longest perpendicular diameter were 25 mm (range 17–49 mm) and 19 mm (range 10–44 mm), respectively. The mean CT attenuation was 38 HU (range 6–62 HU) on contrast-enhanced CT, and was 45 HU (range 26–64 HU) on unenhanced CT (p = 0.41). The CT attenuation was >20 HU in 15 of 18 patients (83%). Preoperative radiological diagnosis included thymoma in 11 patients. Conclusion: In surgically removed, pathologically proven cases of intrathymic cyst, the CT attenuation was >20 HU in most cases, leading to the preoperative diagnosis of thymoma. Awareness of the spectrum of imaging findings of the entity is essential to improve the diagnostic accuracy and patient management. - Highlights: • The most frequent features of intrathymic cysts were oval shape, smooth contour located at midline. • CT attenuation of the cysts was >20HU in most cases and were often diagnosed as thymoma on imaging. • Awareness of the imaging spectrum of intrathymic cyst is essential for better diagnostic accuracy

During the past two decades the incidence of allergies against dental materials has been rising. The most common allergens are nickel, mercury, benzoxyl-peroxide, formaldehyde, MMA, HEMA, EGDMA and TEGDMA. Contact allergy develops in predisposed individuals as a consequence of environmental exposures to allergens. Although the relatively high frequency of contact allergies in children is well documented, its importance during orthodontic treatments is still often underestimated. The most common metal to cause dental allergic reactions is nickel. Nickel-containing metal alloys, such as nickel-titanium, are widely used in orthodontics because of their favorable physical properties. Coated wires (epoxi coating, teflon, etc.) are not only more aesthetic, but can play a role in the orthodontic treatment of patients with nickel allergy. In our case report we present two patients with nickel allergy, and their treatment with alternative orthodontic appliances. During the orthodontic treatment our patients did not have any objective or subjective allergy-related symptoms.

Objectives: To systematically review the literature to assess the quality of evidence related to corticotomy-assisted orthodontic treatment (CAOT) as adjunctive treatment in orthodontics. Methods: The study was conducted in the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia between 2013 and 2014. Various electronic databases were searched and abstracts were retrieved. Defined inclusion criteria were then applied to the obtained original articles for further evaluation by 2 examiners independently. The criteria of selection included human, or animal studies, which assessed some aspects of CAOT and/or the biological principles behind it. Case reports and series were excluded. The quality of the studies was evaluated by the methodological score for clinical trials developed. Results: Fourteen articles were retrieved initially, but only 12 articles were finally selected for the study. The CAOT was found to accelerate tooth movement by 2-2.5 folds when compared with conventional orthodontic tooth movement. The CAOT was found safe on periodontal health and exhibits no or little risk of root resorption. A localized turnover of alveolar spongiosa and the absence of a hyalinized zone was the acceptable biological explanation of CAOT. There is no evidence to support that CAOT enhances the movement of ankylosed teeth, closing old extraction sites, post-orthodontic stability, or transverse expansion. Conclusions: Corticotomy-assisted orthodontic treatment should be considered with caution. Long term randomized clinical trials are still needed. PMID:26108582

Full Text Available Adult patients show reluctance for labial fixed orthodontic treatment owing to poor esthetics. This increased esthetic demand even during treatment led to the development of invisible bracket systems. The best appliance to meet the esthetic requirements and to give complete three-dimensional control to correct any kind of malocclusion is a fixed lingual appliance. However, one of the challenging aspects of lingual orthodontics is anterior torque control. This torque control can be achieved by lever arms in conjunction with mini-implants. The current article presents a case report using customized lingual appliance, lever arms, and mini-implants.

This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

Full Text Available Orthodontic treatment of individuals with metal hypersensitivity is a matter of concern for the orthodontist. Orthodontic appliances contain metals like Nickel, Cobalt and Chromium etc. Metals may cause allergic reactions and are known as allergens. Reaction to these metals is due to biodegradation of metals in the oral cavity. This may lead to the formation of corrosion products and their exposure to the patient. Nickel is the most common metal to cause hypersensitivity reaction. Chromium ranks second among the metals, known to trigger allergic reactions. The adverse biological reactions to these metals may include hypersensitivity, dermatitis and asthma. In addition, a significant carcinogenic and mutagenic potential has been demonstrated. The orthodontist must be familiar with the best possible alternative treatment modalities to provide the safest, most effective care possible in these cases. The present article focuses on the issue of metal hypersensitivity and its management in orthodontic

The application of minimally invasive surgery (MIS) has become increasingly common in urology training programs and clinical practice. Our objective was to review surgical case data from all 12 Canadian residency programs to identify trends in resident exposure to MIS and open procedures. Every year, beginning in 2003, an average of 41 postgraduate year 3 to 5 residents reported surgical case data to a secure internet relational database. Data were anonymized and extracted for the period 2003 to 2009 by measuring a set of 11 predefined index cases that could be performed in both an open and MIS fashion. 16,687 index cases were recorded by a total of 198 residents. As a proportion, there was a significant increase in MIS from 12% in 2003 to 2004 to 32% in 2008 to 2009 (P=0.01). A significant decrease in the proportion of index cases performed with an open approach was also observed from 88% in 2003 to 2004 to 68% in 2008 to 2009 (P=0.01). The majority of these shifts were secondary to the increased application of MIS for nephrectomies of all type (29%-45%), nephroureterectomy (27%-76%), adrenalectomy (15%-71%), and pyeloplasty (17%-54%) (Pfashion during the study period. MIS constitutes an increasingly significant component of surgical volume in Canadian urology residencies with a reciprocal decrease in exposure to open surgery. These trends necessitate ongoing evaluation to maintain the integrity of postgraduate urologic training.

The purpose of this study was to present early and adult cases of anterior open bite that were treated efficiently using different treatment approaches and mechanics. Five patients of different age groups (from 7 to 27 years), suffering from a clear Anterior open bite deformity, were properly diagnosed and relevant treatment modality for each was selected. Positive overbite was efficiently achieved for all patients. Patient compliance is a key factor in using removable habit breakers. However, fixed palatal crib gave the same results but in shorter time. Anterior open bite of skeletal components should be thoroughly evaluated before selecting camouflage or orthognathic surgery treatment modality.

Impaction of mandibular third molars predisposes to pathological conditions including periodontal disease. Extraction of these teeth also may lead to damage to the nerve and to periodontal involvement of the second molars. This report describes a series of cases in which the third molars were orthodontically induced to erupt to prevent the sequelae associated with extraction. Impacted mandibular third molars in 18 patients were surgically exposed following placement of an orthodontic appliance. Depending on the individual case, 1 of 3 approaches was used: attachment of a bracket, placement of a post in the root canal, or placement of an orthodontic wire through a bucco-lingual canal. After suturing the mucoperiosteal flap, the orthodontic appliance was activated. After the tooth erupted, it was removed and periodontal parameters were measured on the second molar. No damage to the inferior alveolar nerve was found. Probing depths on the second molar were reduced from 7.9 +/- 1.6 mm on the buccal and 7.4 +/- 1.0 mm on the lingual to 1.8 +/- 0.7 mm and 1.9 +/- 0. 7 mm, respectively. There was an average gain of 5.0 mm in attachment. Keratinized tissue increased from 2.9 +/- 0.7 to 3.8 +/- 0.6 mm. The interdisiplinary use of periodontics and orthodontics results in non-surgical removal of impacted mandibular third molars without damage to the inferior alveolar nerve and iatrogenic periodontal sequelae to the second molars.

Orthodontics came into being in 1728. Previously, practitioners were at a loss when confronted with crooked teeth. A Latin philosopher had an ingenious flash of orthodontic inspiration. Other authors were content to either extract the malposed teeth or to modify their shape. However, interest in an approach to preventive orthodontics had now begun. © EDP Sciences, SFODF, 2015.

To evaluate the effect of orthodontic stainless steel brackets and two different types of archwires on the diagnostic quality of 3-T MR images. This prospective, case-control study was conducted following Strengthening the Reporting of Observational Studies in Epidemiology guidelines. The recruitment was conducted among orthodontic patients. 80 subjects, requiring MRI for the presence of temporomandibular disorders, were enrolled and divided into four groups: 20 patients using aligners (control group); 20 patients with stainless steel brackets without archwires; 20 patients with stainless steel brackets and nickel-titanium archwires; and 20 patients with stainless steel brackets and stainless steel archwires. Two experts in neuroradiology evaluated the images to determine the amount of distortion in 6 regions and 48 districts. A score was subjectively assigned according to a modified receiver operating characteristic method of distortion classification. Any disagreement was resolved through consensus seeking; when this was not possible, a third neuroradiologist was consulted. The following statistical methods were used: descriptive statistics, Cohen's kappa coefficient (k), Kruskal-Wallis test, pairwise comparisons using the Dunn-Bonferroni approach. The significance was set at p ≤ 0.05. The presence of stainless steel brackets with or without archwires negatively influenced MRI of the cervical region, paranasal sinuses, head and neck region, and cervical vertebrae but did not influence MRI of brain and temporomandibular joint regions. Patients with a stainless steel multibracket orthodontic appliance should remove it before cervical vertebrae, cervical region, paranasal sinuses, and head and neck MRI scans. The brain and temporomandibular joint region MRI should not require the removal of such appliances.
The dentigerous cyst (DC) is the most common type of developmental odontogenic cyst. It is usually asymptomatic and associated with the crown of an unerupted or impacted tooth. However, after a long duration, it is likely to cause significant bone resorption, cortical expansion, and tooth displacement. This report presents a large infected DC in the mandible of a 12-year-old female patient. The DC was located inferior to badly decayed primary molars and surrounded three impacted permanent teeth: canine, first premolar, which had a dilacerated root, and second premolar. The DC was treated successfully by marsupialization and extrusion of the impacted teeth. In conclusion, the combination of marsupialization with orthodontic extrusion is a conservative, efficient protocol that stimulates bone healing and promotes the eruption of cyst-associated teeth even if they are deeply impacted, crowded, or have a dilacerated root. Key words:Dentigerous cyst, marsupialization, impacted teeth, orthodontic extrusion, dilacerated root. PMID:29075422

Full Text Available ABSTRACT Introduction: In dental practice, low-level laser therapy (LLLT and high-intensity laser therapy (HILT are mainly used for dental surgery and biostimulation therapy. Within the Orthodontic specialty, while LLLT has been widely used to treat pain associated with orthodontic movement, accelerate bone regeneration after rapid maxillary expansion, and enhance orthodontic tooth movement, HILT, in turn, has been seen as an alternative for addressing soft tissue complications associated to orthodontic treatment. Objective: The aim of this study is to discuss HILT applications in orthodontic treatment. Methods: This study describes the use of HILT in surgical treatments such as gingivectomy, ulotomy, ulectomy, fiberotomy, labial and lingual frenectomies, as well as hard tissue and other dental restorative materials applications. Conclusion: Despite the many applications for lasers in Orthodontics, they are still underused by Brazilian practitioners. However, it is quite likely that this demand will increase over the next years - following the trend in the USA, where laser therapies are more widely used.

Hormonal and enzymatic factors may render certain individuals more susceptible to orthodontically induced inflammatory root resorption (OIIRR). The objectives of this study are (1) to identify biochemical key markers in blood and saliva that may be correlated to the trend of extensive OIIRR and (2) to utilise these markers to predict a susceptible patient-receiving orthodontic treatment. Nine patients (mean age 23 + 2.9 years) who had moderate to severe OIIRR that assessed via orthopantomograms and met the inclusion criteria were classified as the root resorption group (RRG). Blood chemistry was evaluated using the collection of fasting blood and unstimulated saliva samples. Multiplex enzyme-linked immunosorbent assay (ELISA) arrays were used to screen blood and saliva samples for human cytokines, chemokines and several key enzymes that may play a role in root resorption following orthodontic force application. Biochemical findings from 16 matching subjects were used as the control (CG) for comparative measurements. Patients with moderate to severe OIIRR showed a significant increase in salivary cytokines including interleukin (IL) 7, IL-10, IL-12p70 and interferon-gamma (IFN-γ) level as well as a significant decrease in IL-4 level. Osteocalcin and procollagen type I N-terminal peptide (P1NP) appeared to be the only blood factors that showed a significant difference, more in the CG than the RRG. Saliva might be a more valuable way of measuring changes in cytokine expression than blood secondary to orthodontic treatment. Although the increased expression of pro-inflammatory and anti-inflammatory cytokines may be determinants in the development of moderate to severe OIIRR, cytokine expression may be affected by several potential inflammations in another part of the body. Future research could investigate the cause/effect relationship of different cytokines, in a larger group of patients and at different time intervals, using digital subtraction radiography

Background Rectovaginal fistulas (RVFs) have multiple causes, size and location on which the surgical treatment depends. Description The Authors consider different approaches to RVFs and describe a clinical case of recurrent high RVF. Conclusions Most RVFs can be successfully repaired, although many interventions may be necessary. A colostomy with delayed repair may improve RVFs outcome. Moreover, several authors indicate Mucosal Advancement Flap and Babcock-Bacon technique as the treatments of choice respectively for low and high RVFs (complex and recurrent) and emphasize the placement of endoscopic prothesis in cases of difficult healing of the anastomosis.

The demand and accessibility of orthodontic care has increased but has also been accompanied by patient requests for shorter treatment times. Longer orthodontic treatment increases the risk of decalcification, gingival recession, and root resorption and so shorter treatment times have multiple advantages as well as appealing to patient's desires. Numerous techniques and materials have been suggested to reduce treatment times but, in most cases, are based upon selected case reports with no prospective clinical trials to validate claims. The present review examines many of the current options purported to accelerate orthodontic tooth movement and the level of evidence presently available. There is some evidence to suggest that low-level laser therapy and a corticotomy involving the raising of a muco-periosteal flap are associated with accelerated orthodontic tooth movement; however, the current level of evidence is low to moderate in quality. For this reason, further research is required before routine application could be recommended. © 2017 Australian Dental Association.

Treatment of twins each with one impacted maxillary central incisor and a mesiodens is described. Treatment included rapid expansion, extraction of the mesiodens, surgical exposure of the impacted central incisor, and its forced eruption. The impacted incisor was brought into functional position in one patient but was lost in the other because of insufficient root length and high mobility. Orthodontic, genetic, and periodontal considerations of these 2 cases are evaluated.

Extramedullary hematopoiesis affects about 15% of the patients treated for thalassemia intermedia. Usually seen in adulthood, the most common location is the paraspinal region. Diagnosis and treatment of extramedullary hematopoiesis located in the pelvis of a young 15-year-old girl is discussed. The young age of the patient and the uncommon site of the mass first lead to the diagnosis of an ovarian dermoid cyst. Because of the clinical history and the typical feature on computed tomography scan, extramedullary hematopoiesis was concluded. A specific treatment based on blood transfusion and hydroxyurea was first proposed but remained inefficient. Surgical excision was thus successfully performed. Whereas surgery is limited to spinal cord compression in paraspinal extramedullary hematopoiesis, this observation argues for surgical treatment in symptomatic intraabdominal extramedullary hematopoiesis when medical treatment fails.

Supernumerary teeth are the most common developmental dental anomalies in the maxillary anterior region causing interference to the developing permanent incisors resulting in poor dental and facial esthetics. Two different opinions regarding the timing for surgical removal of the supernumerary teeth are presented. In this case report, three brothers with supernumerary teeth in the maxillary anterior region are presented, their surgical and orthodontic management and outcome are discussed.
Full Text Available Melorheostosis is a rare disease that usually burdens the patient with painful disability or soft tissue compromise. The treatment is usually symptomatic and conservative. Patients with severe and complicated forms of the disease may require surgery. Involvement of the distal part of a limb usually carries more morbidity, such as tumefaction pain, cosmetic and psychosocial or functional problems that render conservative treatment unsatisfactory to patients. In our series, surgical debulking or decompression of the mass effect provided prompt symptom relief.

The aim of the study was to evaluate the effect of post- treatment critical evaluation on the quality of orthodontic care in a postgraduate orthodontic clinic. Orthodontic treatment outcome of 109 consecutively treated cases was evaluated in Phase-I evaluation. Following Phase-I evaluation, PTCE of each case was made mandatory. After 6-years of implementation of compulsory PTCE for each case, orthodontic treatment outcome of all consecutively treated cases (n = 126) was evaluated (Phase-II). The treatment outcome was evaluated by American Board of Orthodontics Model Grading System (ABO MGS) and Subjective evaluation (Visual Analogue Scale, VAS). Based on the ABO scores, the cases were divided into three grades, that is, Grade-I, Grade-II, and Grade-III. The mean total ABO score was improved significantly in Phase-II evaluation (P evaluation (P quality of orthodontic care in a postgraduate orthodontic clinic. Grading one's own treatment improves the quality of future treatment.

Full Text Available This case report presents a patient who is undergoing orthodontic treatment with upper and lower fixed appliance. An interesting point on this case is that the patient only uses Miswak as her oral hygiene tool due to her religious belief. The oral hygiene protocol was allowed and her oral health was closely monitored throughout her orthodontic treatment.
Full Text Available Herein we report treatment for a 19-year-old female patient with severe osteoarthritis of the temporomandibular joint. The patient had severe open bite with a Class II molar relationship. She had limited mouth opening and pain. Clinical examination and magnetic resonance imaging revealed that she had anterior disc displacement without reduction. By splint therapy, limited mouth opening and pain was eliminated, but an anterior open bite developed after the treatment. By orthodontic treatment, an acceptable occlusion was achieved with a Class I molar relationship.
The orthodontic records of 685 patients referred for surgical exposure of an unerupted impacted maxillary canine tooth were examined. The condition was more common among females than males, slightly less than 2:1. The impacted teeth had a palatal-labial ratio of 3:1. All of the teeth were exposed using the open surgical technique and in 98% of cases the tooth erupted and was orthodontically aligned. In 2% of cases ankylosis occurred and the teeth were subsequently extracted. The presence of peg-shaped lateral incisors associated with the impacted maxillary canine tooth was 3.4% of the total number of impacted teeth and congenital absence was found in 1.7% of impacted teeth.

Assess the impact of the implementation of a data-driven scheduling strategy that aimed to improve the access to care of nonelective surgical patients at Massachusetts General Hospital (MGH). Between July 2009 and June 2010, MGH experienced increasing throughput challenges in its perioperative environment: approximately 30% of the nonelective patients were waiting more than the prescribed amount of time to get to surgery, hampering access to care and aggravating the lack of inpatient beds. This work describes the design and implementation of an "open block" strategy: operating room (OR) blocks were reserved for nonelective patients during regular working hours (prime time) and their management centralized. Discrete event simulation showed that 5 rooms would decrease the percentage of delayed patients from 30% to 2%, assuming that OR availability was the only reason for preoperative delay. Implementation began in January 2012. We compare metrics for June through December of 2012 against the same months of 2011. The average preoperative wait time of all nonelective surgical patients decreased by 25.5% (P reason for delay. Rigorous metrics were developed to evaluate its performance. Strong managerial leadership was crucial to enact the new practices and turn them into organizational change.
Full Text Available Background: percutaneous dilatational tracheostomy was invented by ciaglia in 1985. With advent of various instruments, various methods such as Fantoni, Grigges and etc, it became a widesepreadly used method of tracheostomy, especially in intensive care unit wards. In our country this was began in 2005, along with many work shops conducted by anesthesiology department of Tehran University of Medical sciences, with help of specialist from Turin University from ITALY. Case report: In this report two patients who underwent percutaneous dilatational tracheostomy are presented, and are compared with patients who had undergo surgical tracheostomy. Their long and short term complications such as bleeding, injury extents, and recovery was studied and presented. Conclusion: Tracheostomy is an opening in front of neck, in to the trachea, through which breathing is made possible. Percutaneous Dilatational Ttracheostomy (PDT is a method of tracheostomy, in which the need for surgery and transfer of patient to operation room is alleviated. Dispite various benefits, PDT has a few short term and long term drawbacks, which are cartilage fracture, injury to vital structures, perforation of posterior wall, sever bleeding displacement of tube, tracheo-esophageal fistula and trache-oinnominate fistula. Incidence of these complications are lower than surgical tracheostomy. Global reports, especialllly from countries with large scale experiences present a different statistic regarding its success as an alternative method for patients with long surveillance and under mechanical ventilation.

Impaction of deciduous teeth is an uncommon event. The purpose of this report is to describe two unusual eruption failures of a second primary molar and their treatment management. The diagnostic and therapeutic protocol of two cases selected at the Unit of Paediatric Dentistry, Department of Oral and Maxillofacial Science, "Sapienza" University of Rome, Italy, are presented. In both cases, the second deciduous molar was impacted, while no mechanical obstacle like odontomas or supernumerary teeth were present. The two case reports presented in this work are of scientific relevance, due to the rarity of this type of pathology.

Odontomas represent the most prevalent odontogenic tumors in the jaw. The treatment of choice is surgical removal, usually performed by conventional techniques involving ostectomies to expose the tumor. In this paper, the authors describe, through the report of a case of complex odontoma located in the mandibular angle, a more conservative surgical technique called corticotomy, in which the bone removed for access to the tumor (buccal cortical) is repositioned and fixed by titanium plates of 1.5 mm.

Orthodontic treatment for patients with congenitally missing mandibular second premolars can be challenging. Treatment options include keeping the deciduous second molar, extracting the molars and allowing the space to close spontaneously, autotransplantation, prosthetic replacement, and orthodontic space closure. Space closure with orthodontic appliances is demonstrated in this case report.
Full Text Available The present study was conducted on two dogs, one pug and one mongrel presented with the history of swelling at the base of neck. In one of the cases there was ulceration of the skin around the enlarged mass and in the second case there was gradual increase in size of the mass along with bending of neck to one side and reduced appetite. Further, the physical and radiographical examinations were conducted that confirmed the occurrence of tumour in both the cases. Under physical restraint and general anaesthesia the excision of the tumour mass was done along with the proper control of haemorrhage. Both the cases recovered well without any critical symptoms there of up to one year after surgery.

During a seven year period, 51 cases of acquired inguinal herniation in 50 stallions were treated surgically. In 25 cases the herniated loop was ileal, in the other 26 it was jejunal. In cases of strangulation, the vaginal ring was enlarged by incising the peritoneum and transverse fascia. Closure of the superficial inguinal ring was advisable to prevent the hernia recurring. In all cases unilateral castration was performed. Laparotomy was carried out in 33 cases; 22 required intestinal resection and in four cases a bypass was made. Follow-up at least six months postoperatively indicated that surgery had been successful in 76 per cent of the cases treated.

Pheochromocytoma and paraganglioma (PPGL) are rare neoplasms; about 10% are malignant. Literature regarding possible benefit from resection is extremely limited. A 20 year review of all patients undergoing surgery for malignant PPGL at the Mayo Clinic Rochester Campus between 1994 and June 2014 was performed. We identified 34 patients undergoing surgery for malignant PPGL. Median follow up was 6 and 5 years survival was 90% (median 11 years). Complete resection (R0) was achieved in 14 patients (41%). Median disease-free survival was 4.6 years for patients with R0 resection (up to 12 years). Only eight patients (23%) were disease-free on last follow up. Elevated preoperative fractionated metanephrines or catecholamines were documented in 23 patients (68%); these normalized in 13 of 23 patients (56%) postoperatively-with symptom relief in 15 of 18 preoperatively symptomatic patients (79%). Among 23 patients with hormone-producing tumors, significant reduction in number of antihypertensive medications was also noted postoperatively; 11 patients have remained off all antihypertensives, 6 required 1 medication, 1 required 2, while 5 required full blockade with phenoxybenzamine and a beta-adrenergic blocker. Surgery plays a significant role in the management of selected malignant PPGL. Resection can be effective in normalizing or significantly reducing levels of catecholamines and metanephrines, and can improve hormone-related symptoms and hypertension. Surgical resection, either complete or incomplete, is associated with durable survival despite a high rate of tumor recurrence.

Full Text Available Background: Globally, the major causes of neonatal deaths are birth asphyxia, prematurity and severe infections. Little attention is paid to deaths contributed by surgically amenable conditions. This study was undertaken to determine the burden and types of surgical problems encountered in the neonatal period, their outcome and challenges encountered. Patients and Methods: This was a retrospective study. The case notes of all neonates admitted into the newborn unit of our centre between April 2002 and March 2010 with surgical conditions were retrieved and the following information extracted: Sex, diagnosis, age at presentation, surgical intervention and outcome. Results: Out of 7,401 neonates admitted within the study period, 460 (6.2% had a surgical condition. Of the 1,657 babies that died within the same period, 196 (11.8% of them were those with surgical conditions. Congenital abnormalities accounted for 408 (88.7% of all the surgical cases. Intestinal obstruction 129 (31.6%, neural tube defects 101 (24.8% and anterior abdominal wall defect 58 (14.2% were the commonest congenital abnormalities, while fracture of the long bones following birth trauma 15 (28.8% and perforated NEC 14 (26.9% were the commonest acquired conditions. Surgery was performed in 166 (36.1% and 98 (59% had postoperative complications. Significantly, more deaths occurred in preterms than in term babies (P = 0.003 and in those delivered outside the hospital than in in-born babies (P = 0.02. The major cause of death was infection in 92 (47%. Conclusion: Neonatal surgical conditions contributed significantly to both neonatal admissions and overall neonatal mortality and thus highlights the need for investments in newborn surgical care in developing countries.
Full Text Available Background: Extraction in orthodontics are carried out in the cases where there is space deficiency to align the teeth. The elective extraction of first or second premolars has been discussed in the literature for more than 50 years. In the 1940s and 1950s Nance, Dewel and Carey reviewed this as a useful option, and in the 1970s Logan and other leading orthodontists favoured the extraction as choice. It is not always the elective extraction of premolar is a smooth drive for the surgeon as well as to patient. Sometimes the elective extraction of premolar result in complications, which might be due to both anatomical and surgical factors. Methodology: The study sample consisted of 100 patients referred for one or more orthodontic extractions to the department of oral and maxillofacial surgery were included in this retrospective study at the vivekanandha dental college for women tiruchengode between November 2014 and May 2016. All referrals were from the department of orthodontics. A survey was carried out to record the intraoperative risks and correlated with its morbidity as when occured. All intraoperative morbities were managed appropriately as required. Result and Conclusion: Between November 2014 and May 2016, 100 patients had one or more premolar teeth removed by the oral surgeons. The sample size was 100 patients who had a total of 334 premolars removed. The sample's mean age was 11.4+\\- 8.4 years, and 57.0% were male. The average number of teeth extracted per patient was 2.34 +\\- 1.46, and 73.8% had complete root development. More than 93.4% of subjects had normal root and bone morphology, whereas 35.65% had variations in root forms and bone texture. The intra-operative and post operative complication rates were 7.4% and 1.9%, respectively. Complications were generally minor (91.9% and were managed nonoperatively on an outpatient basis. There were no case of oral antral communication.

The aim of this article was to present a new method of analysis using a three dimensional (3D) model of an actual patient with facial asymmetry, for the assessment of her facial changes and the quantification of the deformity. This patient underwent orthodontic and surgical treatment to correct a severe facial asymmetry. The surgical procedure was complex and the case was challenging. The treatment procedure required an orthodontic approach followed by Le Fort I osteotomy, bilateral sagittal split osteotomy, septorhinoplasty and chin advancement. The imaging devices used in this paper is the 3dMDface system (Atlanta, GA) and the Kodak 9500 Cone Beam 3D system device (Atlanta, GA). 3D digital stereophotogrammetric cameras were used for image acquisition and a reverse modeling software package, the Rapidform 2006 Software (INUS Technology, Seoul, Korea) was applied for surface registration. The images were also combined and analyzed using the 3dMD vultus (Atlanta, GA) software and InVivoDental 5.2.3 (San Jose, CA). All data gathered from previously mentioned sources were adjusted to the patient's natural head position. The 3D images of the patient were taken and analyzed in three time frames; before orthodontics and surgical treatment (T1), at the end of orthodontic therapy and before surgery (T2) and about 2 months after surgery (T3). The patient showed significant improvement of her skeletal discrepancy between T1 and T3. In addition, there were some dentoalveolar changes between T1 and T2 as expected. The 3D analysis of surgical changes on the 3D models correlated very well to the actual surgical movements. The use of these 3D imaging tools offer a reliable accuracy to accessing and quantifying changes that occur after surgery. This study shows supportive evidence for the use of 3D imaging techniques.

Full Text Available Objectives. First branchial cleft anomalies (BCAs constitute a rare entity with variable clinical presentations and anatomic findings. Given the high rate of recurrence with incomplete excision, identification of the entire tract during surgical treatment is of paramount importance. The objectives of this paper were to present five anatomic variations of first BCAs and describe the presentation, evaluation, and surgical approach to each one. Methods. A retrospective case review and literature review were performed. We describe patient characteristics, presentation, evaluation, and surgical approach of five patients with first BCAs. Results. Age at definitive surgical treatment ranged from 8 months to 7 years. Various clinical presentations were encountered, some of which were atypical for first BCAs. All had preoperative imaging demonstrating the tract. Four surgical approaches required a superficial parotidectomy with identification of the facial nerve, one of which revealed an aberrant facial nerve. In one case the tract was found to travel into the angle of the mandible, terminating as a mandibular cyst. This required en bloc excision that included the lateral cortex of the mandible. Conclusions. First BCAs have variable presentations. Complete surgical excision can be challenging. Therefore, careful preoperative planning and the recognition of atypical variants during surgery are essential.

Full Text Available OBJECTIVE: Aortopulmonary window (APW is an uncommon congenital malformation. Its clinical presentation is dependent on the size of the defect and on the associated lesions. We evaluated our experience with this anomaly and compared it with 296 cases reported in the literature. METHODS: Retrospective study of 18 patients diagnosed as having APW (age range from 13 days to 31 years, 13 (72.2% females, divided into two groups: Group A (GA: 10 patients with isolated APW, and Group B (GB: 8 patients with associated lesions. RESULTS: Heart failure occurred in 14 patients, and cyanosis in 3: 2 from GB (tetralogy of Fallot - TF, and double outlet right ventricle - DORV, and one from GA with pulmonary hypertension. In 5 patients from GA the diagnosis of mitral regurgitation was made based on a systolic murmur and LV hypertrophy on the EKG. In GB, clinical findings were determined by the associated defect. Diagnosis was established by echocardiography in 11 (61.2% of the patients. In 3 patients, a wrong diagnosis of mitral regurgitation was made, in 1 a patent ductus arteriosus was diagnosed and in 3 others, the diagnosis of APW was masked by other important associated defects (2 cases of DORV and 1 case of TF. The diagnosis was made by catheterization in 3 (16.6% patients, by surgery in 3 (16.6% and by necropsy in 1 (5.5%. Corrective surgery was performed in 14 (77.7% patients, with one immediate death and good long-term follow-up in the remaining patients. CONCLUSION: APW can be confused with other defects. Clinical findings, associated with an adequate echocardiogram can provide the information for the correct diagnosis.
Full Text Available The operative management of giant pituitary prolactinoma represents a significant challenge for neurosurgeons, due to the degree of local tumor infiltration into adjacent structures such as cavernous sinus. The degree of parasellar tumor extension can be classified according to the Knosp grading system’ while suprasellar extension is qualified in accordance with the modified Hardys classification system. This report describes the case of a male patient with a giant pituitary prolactinoma in which a partial tumor resection via a subfrontal approach was achieved. Typically, resection rates of less than 50% have been reported following surgery on giant pituitary adenomas. Prolactin levels were very high, consistent with invasive giant prolactinoma. Our patient was treated with Cabergoline which eventually normalized the prolactin level and significantly reduced the size of the residual tumor. This case serves to illustrate that in the presence of significant suprasellar and parasellar extension, multi-modal treatment strategies with surgery and dopamine agonist, is the gold standard in the management of locally aggressive pituitary prolactinomas.
Full Text Available Abstract Thyrotoxic hypokalemic periodic paralysis (THPP is a rare, potentially life-threatening endocrine emergency. It is characterized by recurrent muscle weakness and hypokalemia. Because many THPP patients do not have obvious symptoms and signs of hyperthyroidism, misdiagnosis may occur. The published studies revealed that definitive therapy for THPP is control of hyperthyroidism by medical therapy, radioactive iodine or surgery, but the long-term post-operative follow-up result was not observed. We reported two cases of medically refractory THPP with recurrent paralysis of extremities and hypokalemia, and both were combined with thyroid nodules. Both patients were treated with total thyroidectomy; the pathology revealed that one is Graves' disease with thyroid papillary carcinoma, and the other is adenomatous goiter with papillary hyperplasia. No episode of periodic paralysis was noted and laboratory evaluation revealed normal potassium level during the post-operative follow up. Our experience suggests that total thyroidectomy by experienced surgeon is an appropriate and definite treatment for medically refractory THPP, especially in cases combined with thyroid nodules.

Outbreaks of viral haemorrhagic fevers such as Ebola can lead to imported cases in Europe and America. The eventuality of surgery in the setting of Ebola Virus Disease (EVD) is low, but the Spanish Association of Surgeons elaborated a surgical protocol for EVD. Elective surgical procedures are not indicated. Emergency cases can be considered in: persons under investigation, possible cases and early confirmed cases. In some conditions usually treated by surgery a medical treatment can be tested. All cases must be treated in high technology hospitals. These hospitals must be equipped with adequate means for healthcare provider's protection. All members of the healthcare team should practice thorough simulation prior to caring for a possible Ebola patient. This protocol is based on international guidelines on use of Personal Protective Equipment, protocols of other scientific societies, and specific recommendations for the operating room environment.

Full Text Available Abstract Introduction Quadratus femoris tear is an uncommon injury, which is only rarely reported in the literature. In the majority of cases the correct diagnosis is delayed due to non-specific symptoms and signs. A magnetic resonance imaging scan is crucial in the differential diagnosis since injuries to contiguous soft tissues may present with similar symptoms. Presentation with sciatica is not reported in the few cases existing in the English literature and the reported treatment has always been conservative. Case presentation We report here on a case of quadratus femoris tear in a 22-year-old Greek woman who presented with persistent sciatica. She was unresponsive to conservative measures and so was treated with surgical decompression. Conclusion The correct diagnosis of quadratus muscle tear is a challenge for physicians. The treatment is usually conservative, but in cases of persistent sciatica surgical decompression is an alternative option.

Odontogenic myxoma is a benign odontogenic tumor with locally aggressive behavior, and is relatively rare in the oral cavity. There are currently no clear surgical management guidelines for odontogenic myxoma, and a variety of approaches may be used. This study evaluated the literature concerning the surgical management of odontogenic myxoma, and reports the long-term outcome of a case managed by using a more conservative surgical approach. We managed a 40-year-old Japanese man with odontogenic myxoma in the right mandible by enucleation and curettage, a relatively conservative approach that has proved to have been justified by a lack of recurrence over 10 years. Our strategy was compared with others reported in the literature, which was identified by a PubMed search using the term "odontogenic myxoma". Articles without full text or with missing data were excluded. The age and sex of patients, the tumor location (maxilla/mandible), treatment (conservative/radical), recurrence, and follow-up period were compared in the reported cases that we evaluated. From the initial 211 studies identified, 20 studies qualified as mandibular cases of odontogenic myxoma. Recurrence was reported in three cases that had been treated with a more conservative surgical approach. Enucleation and curettage has proved an effective approach in several cases in ours there has been no recurrence more than 10 years after surgery but the risk of recurrence appears to be higher. We discuss the important factors that must be considered when determining the correct management approach to odontogenic myxoma.

Full Text Available Background: Beside bracket position, the timing of bracket placement is one of the most essential in orthodontic treatment with fixed appliances. Even it seems simple the timing of bracket placement can be crucial and significantly influence the result of orthodontic treatment. However it is often found brackets are placed without complete understanding of its purpose and effects, which could be useless and even detrimental for the case. Purpose: The aim of this case report is to show that the timing of bracket placement could be different depending on the cases. Case: Five different cases are presented here with different timing of bracket placement. Case management: On these cases, brackets were placed on the upper arch first, on the lower arch first, or even only on some teeth first. Good and efficient orthodontic treatment results were achieved. Conclusion: For every orthodontic case, from the very beginning of treatment, bracket should be placed with the end result in mind. If brackets are correctly placed at a correct time, better treatment result could be achieved without unnecessary round tripping tooth movement.

Appearance is the most important motivating factor for patients seeking orthodontic treatment and is self-evident that these patients would prefer an appliance that is less visible. Lingual "invisible" Appliances offer the best option to the patient seeking aesthetic correction for their malocclusion. A group of such patients who do not want their appliances to be visible also require surgical correction. Lingual appliance being comparable to the labial counterpart provides the opportunity of...

Full Text Available Bouveret's syndrome is a high mechanical obstruction due to impaction of a gallstone into the duodenum, through a cholecystoduodenal fistula. It belongs to a larger group of gallstone ileus, a disease which occurs after developing a fistula between the gallbladder and the gastrointestinal tract. This is a rare complication of gallstones but because it appears in elderly people, it has a high morbidity and mortality. Patients have various symptoms and the treatment is individualized. We present here a case of a 67 years old patient, admitted in emergency, presenting symptoms of high bowel obstruction, with onset 5 days before admission. Abdominal ultrasound reveals a 5 cm stone that seems to be in the gallbladder, gastric stasis and at gastroscopy appears a foreign body impacted in the duodenum. After a short preparation the patient underwent surgery. We found a dilated stomach and a large cholecystoduodenal fistula with an impacted gallstone in the duodenum. We performed one stage surgery: cholecystectomy, extraction of the stone and suturing of the fistula. We reestablished the continuity of the intestinal tract. We performed also an ileostomy for feeding the patient and protecting the anastomoses. The postoperative evolution was favorable.

TMJ osteoarthrosis and internal derangements are in close connection, representing a substantial portion of temporomandibular disorders. The authors wish to underline the role of surgery in the treatment of this degenerative disease to improve function and to alleviate pain. A 63 year-old woman suffering from closed-lock with reduced opening movements was accepted in our Department in March, 1995. Clinical and radiological evaluations showed bilateral closed lock and severe TMJ osteoarthrosis. Occlusal, pharmacological and physical therapy were performed for one year, without results. Bilateral condylectomy and diskectomy with arthroplasty were carried out. Immediate muscular rehabilitation after surgery was performed by the patient. Follow-up 3, 6, 12 months after surgery were carried out. Full opening movements and reduction of pain were obtained 20 days after surgery. The patient, followed-up one year after surgery, presented effective mandibular movements and adequate amelioration of clinical picture. TMJ surgery in association with physical therapy represents in selected cases an adequate procedure for the treatment of TMJ degenerative disease.

Our purpose in this case report is to present an orthodontic treatment obtained and the results achieved in 17-year-old white female patient with Angle Class II malocclusion and bilateral posterior crossbite. Patient was treated with bonded acrylic Hyrax appliance and surgically assisted rapid maxillary expansion (SARME). The multiloop system 0.16 TMA (ß titanium) arch wire was used in the alignment phase and on purpose to prohibit bite opening and optimize threedimensional movement control. After treatment bonded lingual retainers were placed in between maxillary central incisors and in mandible canine-to-canine. A functional removable Klammt appliance was used for retention. The 3D Laser Scanner Roland LPX-250 was used in order to obtain digital dental casts. Evaluation of the treatment results was measured on these models and using finite element scaling analysis (FESA). An Angle Class I relationship was obtained after 2½ years of treatment, function and facial aesthetics were improved. The shape of the palate changed significant in the width direction, not significantly in length and high direction. The greatest expansion of palate was found in the region between the palatal cusps of the first molars 26.6%, followed by first 21.9% and second premolars 16.5%. SARME in adult patients with bilateral cross bite and maxillary deficiency lead to satisfactory results. The 3D laser scanned models and their measurements, using advanced software's are successfully used for precise studies.

Peri-implantitis, a clinical term describing the inflammatory process that affects the soft and hard tissues around an osseointegrated implant, may lead to peri-implant pocket formation and loss of supporting bone. However, this imprecise definition has resulted in a wide variation of the reported prevalence; ≥10% of implants and 20% of patients over a 5- to 10-year period after implantation has been reported. The individual reporting of bone loss, bleeding on probing, pocket probing depth and inconsistent recording of results has led to this variation in the prevalence. Thus, a specific definition of peri-implantitis is needed. This paper describes the vast variation existing in the definition of peri-implantitis and suggests a logical way to record the degree and prevalence of the condition. The evaluation of bone loss must be made within the concept of natural physiological bony remodelling according to the initial peri-implant hard and soft tissue damage and actual definitive load of the implant. Therefore, the reason for bone loss must be determined as either a result of the individual osseous remodelling process or a response to infection. The most current Papers and Consensus of Opinion describing peri-implantitis are presented to illustrate the dilemma that periodontologists and implant surgeons are faced with when diagnosing the degree of the disease process and the necessary treatment regime that will be required. The treatment of peri-implantitis should be determined by its severity. A case of advanced peri-implantitis is at risk of extreme implant exposure that results in a loss of soft tissue morphology and keratinized gingival tissue. Loss of bone at the implant surface may lead to loss of bone at any adjacent natural teeth or implants. Thus, if early detection of peri-implantitis has not occurred and the disease process progresses to advanced peri-implantitis, the compromised hard and soft tissues will require extensive, skill

Full Text Available Odontomas are a heterogeneous group of jaw bone lesions, classified as odontogenic tumors which usually include well-diversified dental tissues. Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. Two types of odontomas are described: compound and complex based on either the appearance of well-organized tooth-like structures (compound odontomas or on a mass of disorganized odontogenic tissues (complex odontomas. Compound odontomas have a predilection for the anterior maxilla, whereas complex odontomas have a predilection for the posterior mandible. Odontomas frequently interfere with eruption of teeth leading to their impaction. This is a case report of a 14-year-old girl with an unerupted maxillary right central incisor due to a complex composite odontoma a rare occurrence in anterior maxilla. Surgical excision of the odontoma and orthodontic treatment to get the impacted maxillary right central incisor into alignment is discussed.

Melanoma of the nasal cavity is a rare tumor with a worse prognosis than cutaneous melanoma. It usually presents as nasal obstruction and/or epistaxis. The observation of a pigmented mass in the nasal cavity is highly suggestive of this lesion. Computed tomography shows a mass with nonspecific features. In magnetic resonance studies, it has a characteristics signal consisting of hyperintensity of T1-weighted images and hypointensity on T2-weighted images, depending on the amount of melanin. The treatment of choice is surgical resection. We present a case of melanoma of the nasal cavity in which endovascular embolization of the tumor was performed prior to surgical treatment.

Full Text Available Abstract Introduction Smith-Magenis syndrome is a rare genetic condition associated with scoliosis in approximately 30% of cases. There is limited information in the literature on the treatment of scoliosis and the surgical outcome in patients with this condition. Characteristic features of the syndrome, such as the presence of congenital heart and renal disease, inherent immunodeficiency, as well as severe behavioural disorders may complicate the surgical treatment of patients. Case presentation We present the case of an 11-year-old British Caucasian girl with Smith-Magenis syndrome who developed a severe, progressive thoracic and lumbar scoliosis measuring 85° and 80°, respectively. She had no cardiac or renal anomalies. Brace treatment was unsuccessful to prevent deterioration of the scoliosis. Both curves were rigid on supine maximum side-bending and traction radiographs. Our patient underwent a posterior spinal arthrodesis with pedicle screw/hook and rod instrumentation and autologous iliac crest graft, supplemented by allograft bone. She had an uneventful postoperative course other than the development of a small wound dehiscence which required resuturing with no signs of a wound infection. A good correction of both scoliotic curvatures to 45° and 40° and a balanced spine in both the coronal and sagittal planes was achieved. Follow-up to skeletal maturity (4 years post-surgery showed no loss of deformity correction, no detected pseudarthrosis and a good clinical outcome. Conclusion Patients with Smith-Magenis syndrome can develop a severe scoliosis that may require surgical treatment. Congenital cardiac and renal disease, immunodeficiency and severe behavioural problems can affect the surgical outcome following spinal arthrodesis and need to be taken into consideration. Our case demonstrates that surgical correction of the deformity can be performed safely on this group of patients, with a good outcome and an uncomplicated

This pilot study was performed to test the hypothesis that an orthodontic oral appliance (OA) that is designed to work against the backwardly directed forces on the upper incisors may counteract the reduction in overjet from these devices. Thirty patients with normal bites, good oral health, and milder sleep apnea were randomized to treatment with either OAs or orthodontic OAs. Bite changes were evaluated on plaster casts and radiographs and by questionnaires after a mean of 2.4 years in 19 frequent users. Four of nine patients in the orthodontic OA group increased their overjet by > or =0.4 mm, while none of the 10 patients in the OA group experienced that effect. Only the orthodontic OA increases the overjet; this design may therefore be beneficial to patients at risk of negative effects on their bite during OA treatment.

Nickel is the most common metal to cause contact dermatitis in orthodontics. Nickel-containing metal alloys, such as nickel-titanium and stainless steel, are widely used in orthodontic appliances. Nickel-titanium alloys may have nickel content in excess of 50 per cent and can thus potentially release enough nickel in the oral environment to elicit manifestations of an allergic reaction. Stainless steel has a lower nickel content (8 per cent). However, because the nickel is bound in a crystal lattice it is not available to react. Stainless steel orthodontic components are therefore very unlikely to cause nickel hypersensitivity. This article discusses the diagnosis of nickel allergy in orthodontics and describes alternative products that are nickel free or have a very low nickel content, which would be appropriate to use in patients diagnosed with a nickel allergy.

Full Text Available Group A Streptococcus (GAS causing puerperal sepsis is a leading cause of maternal mortality worldwide. Although rare, GAS infection is a relatively significant public health concern because of its propensity to evolve rapidly into septic shock, streptococcal toxic shock syndrome, and death. We report the case of a 27-year-old patient who presented with GAS septic shock after undergoing a surgical termination of pregnancy and was treated successfully and recovered without sequelae. GAS septic shock should always be included in the differential diagnosis of any patient who develops sepsis after a surgical abortion. Patients with GAS septic shock have a rapid clinical decline and need aggressive fluid management, early initiation of broad-spectrum antibiotics, and rapid surgical intervention.

Full Text Available Objective:To perform surgical operation on necrotizing fasciitis due to odontegenic infection with sepsis. Methods: In this case an odontogenic infection was accompanied by a large open wound on the face and sepsis. Patient was hospitalized in the Dr.HasanSadikin General Hospital. Management of this patient in the emergency room were administration of appropriate broad-spectrum empiric antibiotic, incision and pus drainage, and extraction of the infected tooth, followed by fluid resuscitation with strict observation. Surgical debridement was then performed. Results:After being treated for 12 days the patient’s condition improved. We planned closure of defects of the facial area, but the patient refused. Conclusion: Necrotizing fasciitis is an uncommon but potentially lethal condition associated with high rates of morbidity and mortality. Early diagnosis coupled with emergent surgical debridement, appropriate broad-spectrum empiric antibiotic treatment, and a multidisciplinary team approach is essential for successful treatment.
Full Text Available Context - Uterine scar defects or scar niche are relatively common after cesarean delivery. An association has been observed between the severity of scar defect, also known as isthmocele, some gynecologic symptoms, and the risk of uterine scar dehiscence at the next delivery. It has been suggested that surgical repair of scar defect could improve the gynecological symptoms, but it remains unclear whether such surgery mends the uterine scar itself. Case Report - We report the case of a woman with uterine scar defect in whom laparoscopic repair significantly improved the gynecological symptoms without affecting the uterine scar, evaluated by hysterosonography. Conclusion - This case highlights the significant dearth of knowledge surrounding the diagnosis, consequences, and benefits of surgical repair of uterine scar defect after cesarean.

The aim of the study is codify both a methodological and communication standard based on teleassistance, and the emergencies that can be treated from a remote location along with the related clinical applications, limitations, medicolegal considerations and the patients' opinion on this new opportunity of assistance. To codify a distance communication method, ten young patients aged 10-16 years, equipped with a mobile videophone and after clear instructions, asked the advice of the orthodontic specialist to deal with minor orthodontic emergencies. Upon completion of the treatment they filled out a questionnaire on satisfaction level and difficulties encountered with the use of this technology. Most of the orthodontic emergencies can be solved at home: rubber ligature displacement, discomfort due to the appliance, irritation of cheeks. Those patients who used the videophone to handle the orthodontic emergencies considered it an easy and useful method, possibly due to the young age of the subjects involved, who are familiar with the new technologies. Telecommunications applied to medicine and dentistry is currently a subject of topical interest. The most developed countries are investing resources in order to improve assistance and communication between physicians and patients and among specialists. The possibility of sharing videos and images is particularly useful in the orthodontic field, as minor emergencies can be solved easily at home, reassuring patient and parents on one hand, and limiting visits to the dental office to cases of real need.

Full Text Available Purpose: This study aimed to evaluate the safety and efficacy of retropupillary fixation of an iris-claw intraocular lens (IOL; Verisyse polymethyl methacrylate IOL, Abbott Medical Optics [AMO], Netherlands for the surgical correction of aphakia in microspherophakic eyes without sufficient capsular support. Design: This was a prospective, interventional, noncomparative case series. Methods: This interventional case series comprised 17 eyes of 9 microspherophakic patients. Retropupillary fixation of the Verisyse iris-claw IOL (AMO was performed in all cases. The surgical time was measured. Corrected distance visual acuity, astigmatism, intraocular pressure (IOP, tissue reaction, pigment dispersion, and stability of the IOL were studied 1 day, 3 days, 1 week, 2 weeks, 1 month, and 6 months postoperatively. Results: Eight patients had familial microspherophakia and one patient had Marfan's syndrome. Eighty-two percent of the cases achieved a visual acuity of 0.3 or better. There was no significant postoperative inflammatory reaction. Transient elevation of IOP was recorded in two cases in the 1st week only. One IOL developed disengagement of one of the haptics from the iris and was successfully re-engaged. All the other IOLs were well centered and stable. The mean surgical time was 18.0 ± 4.5 min. Conclusions: Retropupillary fixation of an iris-claw IOL is a safe and effective procedure that provides early visual recovery. It is also a time-saving method for correcting aphakia in microspherophakic eyes without sufficient capsular support.

Published information describing the clinical features and outcome for dogs with epiglottic retroversion (ER) is limited. To describe clinical features, comorbidities, outcome of surgical versus medical treatment and long-term follow-up for dogs with ER. We hypothesized that dogs with ER would have upper airway comorbidities and that surgical management (epiglottopexy or subtotal epiglottectomy) would improve long-term outcome compared to medical management alone. Twenty-four client-owned dogs. Retrospective review of medical records to identify dogs with ER that underwent surgical or medical management of ER. Dogs with ER commonly were middle-aged to older, small breed, spayed females with body condition score (BCS) ≥6/9. Stridor and dyspnea were the most common presenting signs. Concurrent or historical upper airway disorders were documented in 79.1% of cases. At last evaluation, 52.6% of dogs that underwent surgical management, and 60% of dogs that received medical management alone, had decreased severity of presenting clinical signs. In dogs that underwent surgical management for ER, the incidence of respiratory crisis decreased from 62.5% before surgery to 25% after surgical treatment. The overall calculated Kaplan-Meier median survival time was 875 days. Our study indicated that a long-term survival of at least 2 years can be expected in dogs diagnosed with epiglottic retroversion. The necessity of surgical management cannot be determined based on this data, but dogs with no concurrent upper airway disorders may benefit from a permanent epiglottopexy to alleviate negative inspiratory pressures.

We examined a large series of biopsy-proven invasive cervical cancers with surgical staging and HPV re-testing to estimate the relevance of HPV-negative cervical cancers in a Caucasian population. We prospectively collected smears from 371 patients with a biopsy-proven diagnosis of cervical cancer for HC2 testing of high-risk HPV (HR-HPV). In HC2-negative cases, smears and paraffin embedded tissue blocks underwent additional HPV genotyping. HC2 tests showed 31/371 cases (8.8%) had negative findings. Surgical staging showed that 21/31 HC2-negative cases (68%) were not cervical cancer. Overall, 340/350 cases of primary cervical cancer confirmed by surgical staging tested HC2 positive (97.2%). Non-high-risk HPV subtypes were detected in five cases (one HPV-53, one HPV-70, and three HPV-73) and high-risk subtypes in four patients with HC2-negative cervical cancer (two HPV 16 and two HPV-18). The remaining case, a primary undifferentiated carcinoma of the uterine cervix, tested negative for HPV-DNA with all tests. The main explanation for HPV-negative cervical cancer was a false diagnosis, followed by cancers associated with non-HR-HPV types, and false-negative HR-HPV results. Truly HPV negative seem to be very rare in Caucasian populations. Retrospective analyses without surgical staging may overestimate the proportion of HPV negative cervical cancers.

The aim of this second article of the three part series is to sum up the current developments in lingual orthodontics. This article attempts to review the development, advantages and disadvantages, bonding techniques, bracket mechanics, patient factors and types of lingual appliance systems available. In addition, the article shows examples of treated cases with lingual appliances. Lingual appliances are a useful addition to the armamentarium of invisible orthodontic appliances, with significant developments over the last few years. Clinicians need to be aware of the advances and predictable results achievable with lingual appliances.

Prospective database study. To grasp the characteristics of surgically treated cases with lumbar spondylolysis or isthmic spondylolisthesis. A detailed analysis of surgically treated cases with spondylolysis or isthmic spondylolisthesis has never been reported. An epidemiological study in Japan conducted on 2000 subjects found the incidence of lumbar spondylolysis in the Japanese general population (population-based study) to be 5.9% (males: 7.9%, females: 3.9%). Among 124 vertebrae with spondylolysis, there were 0.8% L2 lesions, 3.2% L3 lesions, 5.6% L4 lesions, and 90.3% L5 lesions, including 5 cases (4.3%) with multiple-level lesions. We have been registering surgically treated spine cases in our database since 2000. From this database, we prospectively collected cases with lumbar spondylolysis or isthmic spondylolisthesis that were treated surgically between January 2000 and December 2009. We determined the age at surgery, sex, and vertebral level of spondylolysis. Of the 564 spondylolysis patients treated surgically, 66.8% were male and 33.2% were female. The mean age at surgery was 52.5 years (range, 13-84 y). There were 585 vertebrae with spondylolysis including 21 cases (3.7%) with multiple-level lesions. L5 spondylolysis affected 432 vertebrae and was the most common location (73.8%), followed by 125 L4 lesions (21.4%), 24 L3 lesions (4.1%), and 2 L2 lesions (0.7%). The percentage of L4 lesions in our study was significantly higher and of L5 lesions was significantly lower than those lesions' percentages in the population-based study. L4 spondylolysis may be more unstable or cause clinical symptoms more frequently leading to more surgical intervention. The percentage of multiple-level spondylolysis was similar between the 2 studies, suggesting these patients respond relatively well to conservative treatment. The male/female ratio was 2:1 in both studies, indicating that males and females require surgery at a similar frequency.

The clinical course of patients suffering from chronic thromboembolic pulmonary hypertension (CTEPH) depends on the distribution pattern of the thromboembolic material. In patients with thromboembolic findings in the central pulmonary segments pulmonary thrombendarterectomy (PTE) has excellent results and acceptable operative risk. This paper presents two surgically inaccessable cases that were successfully treated with balloon pulmonary angioplasty. Balloon angioplasty improved parenchymal perfusion, increased cardiac index (ΔCI + 19.2% [Case 1], and + 15.4% ), reduced pulmonary vascular resistance during follow-up (ΔPVRI - 25.0%  and - 15.9% ), and is discussed as an alternative treatment option for cases not suited for surgery.

The writing committee for Antithrombotic Therapy for Venous Thromboembolic Disease of the 2008 ACCP guidelines made the following recommendations for thrombus removal strategies in patients with deep vein thrombosis (DVT): open surgical thrombectomy is recommended in patients with acute iliofemoral DVT to reduce symptoms and post-thrombotic morbidity; whenever available, catheter-directed thrombolysis is preferred to surgical venous thrombectomy, the risk of hemorrhage being diminished; surgical venous thrombectomy is recognized to be efficient in cases where catheter-directed thrombolysis is unavailable or the patients are not suitable candidates for such a procedure. Randomized studies comparing surgical thrombectomy and anticoagulant therapy in patients with iliofemoral DVT (IFDVT) showed that at 6 months, 5 years, and 10 years the patients in the thrombectomy group presented increased permeability, lower venous pressure, less edema, and fewer postthrombotic symptoms compared to the patients receiving anticoagulant therapy. In this article we present 3 cases of IFDVT in postpartum patients diagnosed by Doppler ultrasound of the deep venous system. The 3 patients received anticoagulant therapy prior to surgery. Surgery consisted in thrombectomy of the common, superficial and deep femoral veins, external and internal iliac veins, and femoral-saphenous arteriovenous fistula. The patients received postoperative antithrombotic therapy and were followed-up at 3, 6 and 9 months by Doppler ultrasound of the deep venous system.

The purpose of this case report is to highlight for the first time the way Medical Infrared Thermography can be a helpful tool to assist the surgeon in the surgical treatment of Hidradenitis Suppurativa inflammatory disease. A 36-year-old man with a 7-year history of Hidradenitis Suppurativa presented inflammatory nodules in the left axilla area corresponding to Hurley stage II. Choice is made to surgically treat this patient using a wide excision protocol combined with a postoperative second intention healing. For the study purpose, an IR FLIR SC620 camera (FLIR Systems, Wilsonville, OR), having a high resolution pixel detector of 640×480 pixels for greater accuracy and higher resolution, has been used. For the first time in the literature, this case report on HS disease supports the idea that real-time medical infrared thermography may be helpful in establishing the true extent of disease preoperatively in the surgical room and in a similar manner, that this technique allows the surgeon to ensure all diseased lesions are removed during surgery. At least, medical infrared thermography seems to be a powerful tool to control the final wide surgical wound, in order to minimize recurrence risk of such a disease. Copyright © 2017 The Author(s).

To characterize the nature of surgical preparation among otolaryngology residents nationwide, determine the self-rated effectiveness and efficiency of case preparation practices, and identify potential means for educational improvement. A survey examining the study objectives was developed and distributed to otolaryngology residents nationwide. Survey response data were submitted to descriptive analysis and comparative analyses between junior and senior residents. Literature regarding case preparation among otolaryngology residents was reviewed. Among 108 resident respondents, the most commonly used resources included textbooks (86.1%), surgical education websites (74.1%), and surgical atlases (66.7%). Time was the primary limitation (cited by 84.3%) and convenience the predominant factor influencing resource selection (92.5%). On a 5-point Likert scale, mean scores regarding effectiveness and efficiency of case preparation were 3.53 ± 0.68 and 3.19 ± 0.88, respectively. Senior residents compared to junior residents were more likely to rate their preparation as effective (3.75 ± 0.54 vs 3.40 ± 0.72, P = .008) and efficient (3.45 ± 0.85 vs 3.03 ± 0.86, P = .02). Otolaryngology residents do not consistently rate their case preparation as effective or efficient. While there appears to be progress in self-directed learning throughout residency, room for improvement remains, with potential avenues for such improvement explored here.

In-flight medical and surgical emergencies (IMEs) onboard commercial aircrafts occur quite commonly. However, little epidemiological research exists concerning these incidents. Thirty-two European airlines were asked to provide anonymous data on medical flight reports of IMEs for the years 2002 to 2007. The total number of incidents was correlated to revenue passenger kilometers (rpk). Additionally, on-board births and deaths, flight diversions, flight routes (continental/intercontinental) and involvement of a physician or medical professional in providing therapy were analysed. Only four airlines, of which two participated in this study, were able to provide the necessary data. A total of 10,189 cases of IMEs were analysed. Syncope was the most common medical condition reported (5307 cases, 53.5%) followed by gastrointestinal disorders (926 cases, 8.9%) and cardiac conditions (509 cases, 4.9%). The most common surgical conditions were thrombosis (47 cases, 0.5%) and appendicitis (27 cases, 0.25%). In 2.8% of all IMEs, an aircraft diversion was performed. In 86% of cases, a physician or medical professional was involved in providing therapy. A mean (standard deviation) of 14 (+/- 2.3, 10.8 to 16.6 interquartile range) IMEs per billion rpk was calculated. The study demonstrates that although aviation is regulated by a variety of national and international laws, standardised documentation of IMEs is inadequate and needs further development.

Orthodontics like any other specialty has much to offer law enforcement in the detection and solution of crime or in civil proceedings. Forensic odontology often requires an interdisciplinary approach towards dentistry for the purpose of proper diagnosis of cases. In cases where the forensic odontologist has to establish a person’s identity, an orthodontist can be of great help at times. Teeth, with their anatomic/physiologic variations and therapy such as orthodontic treatment, restorations ...

To correct dentofacial deformities, three-dimensional skeletal analysis and computerized orthognathic surgery simulation are used to facilitate accurate diagnoses and surgical plans. Computed tomography imaging of dental occlusion can inform three-dimensional facial analyses and orthognathic surgical simulations. Furthermore, three-dimensional laser scans of a cast model of the predetermined postoperative dental occlusion can be used to increase the accuracy of the preoperative surgical simulation. In this study, we prepared cast models of planned postoperative dental occlusions from 12 patients diagnosed with skeletal class III malocclusions with mandibular prognathism and facial asymmetry that had planned to undergo bimaxillary orthognathic surgery during preoperative orthodontic treatment. The data from three-dimensional laser scans of the cast models were used in three-dimensional surgical simulations. Early orthognathic surgeries were performed based on three-dimensional image simulations using the cast images in several presurgical orthodontic states in which teeth alignment, leveling, and space closure were incomplete. After postoperative orthodontic treatments, intraoral examinations revealed that no patient had a posterior open bite or space. The two-dimensional and three-dimensional skeletal analyses showed that no mandibular deviations occurred between the immediate and final postoperative states of orthodontic treatment. These results showed that early orthognathic surgery with three-dimensional computerized simulations based on cast models of predetermined postoperative dental occlusions could provide early correction of facial deformities and improved efficacy of preoperative orthodontic treatment. This approach can reduce the decompensation treatment period of the presurgical orthodontics and contribute to efficient postoperative orthodontic treatments.

This study aimed to identify (1) the thalamic gliomas suitable for surgical resection and (2) the appropriate surgical approach based on their location and the displacement of the posterior limb of the internal capsule (PLIC). A retrospective study over a 5-year period (from 2006 to 2010) was performed in 41 patients with thalamic gliomas. The mean age of these patients was 20.4 years (range, 2-65 years). Twenty (49 %) tumors were thalamic, 19 (46 %) were thalamopeduncular, and 2 (5 %) were bilateral. The PLIC, based on T2-weighted magnetic resonance axial sections, was displaced anterolaterally in 23 (56 %) cases and laterally in 6 (14 %) cases. It was involved by lesion in eight (20 %) cases and could not be identified in four (10 %) cases. Resection, favored in patients with well-defined, contrast-enhancing lesions, was performed in 34 (83 %) cases, while a biopsy was resorted to in 7 (17 %) cases. A gross total resection or near total resection (>90 %) could be achieved in 26 (63 %) cases. The middle temporal gyrus approach, used when the PLIC was displaced anterolaterally, was the commonly used approach (63.5 %). Common pathologies were pilocytic astrocytoma (58 %) in children and grade III/IV astrocytomas (86 %) in adults. Preoperative motor deficits improved in 64 % of the patients with pilocytic lesions as compared to 0 % in patients with grade III/IV lesions (P value, 0.001). Postoperatively, two patients (5 %) had marginal worsening of motor power, two patients developed visual field defects, and one patient developed a third nerve paresis. Radical resection of thalamic gliomas is a useful treatment modality in a select subset of patients and is the treatment of choice for pilocytic astrocytomas. Tailoring the surgical approach, depending on the relative position of the PLIC, has an important bearing on outcome.

Amalgam tattoos in the gingiva and mucosa can interfere with esthetics and present a barrier to surface-to-bone contact at implant sites. Two clinical cases are used to illustrate the effectiveness of acellular dermal matrix allografts in the treatment of these lesions. Very esthetic results were obtained with minimal discomfort and postoperative complications because of the prevention of a second surgical site or additional procedure.

Despite increasing demand for lingual orthodontics, the technique is not very popular among the orthodontists in general. Lingual orthodontics differs from the conventional labial technique in all aspects. Lack of comprehensive training in this field is a major obstacle in popularizing this science of invisible orthodontics. At present, short-term courses and part-time degree programs are the means to learn this technique and the demand for more comprehensive lingual orthodontic education is ...

Full Text Available Obstructive Sleep Apnea Syndrome (OSA is a multifactorial disease that highly alters a persons quality of life. It is characterized by the repeated interruption of breathing during sleep, due to an obstruction or the collapse of the upper airways. Since it is a multifactorial etiological disorder, it requires a thorough diagnosis and treatment with an interdisciplinary team, which comprises several professionals such as a surgical dentist, phonoaudiologist, otorhinolaryngologist, sleep doctor, neurologist and physiotherapist. The diagnosis and the degree of severity of the syndrome is determined through a polysomnography examination. After that, the best form of treatment is devised depending on the gravity of the case. In cases of moderate to severe apnea, invasive treatment through surgical procedures such as maxillomandibular advancement remains the preferred option as it increases the posterior air space, reducing and/or eliminating the obstruction. Thus, improving the patients respiratory function and, consequently, his quality of life as it is shown in the clinical case at hand. In which the male patient, facial pattern type I, 41 years of age, diagnosed with moderate OSA (Apnea-Hypopnea Index - AHI of 23.19, decided to have a surgical treatment instead of a conservative one, resulting in the cure of apnea (AHI of 0.3.

Retroperitoneal hemorrhagic bleeding is a known manifestation of Type-IV Ehlers-Danlos Syndrome that is caused by loss-of-function mutations of the pro-alpha-1 chains of type III pro-collagen (COL3A1) resulting in vascular fragility. A number of previous reports describe futile surgical intervention for retroperitoneal bleeding in Type-IV Ehlers-Danlos Syndrome with high post-operative mortality, although the rarity of retroperitoneal bleeding associated with Type-IV Ehlers-Danlos Syndrome precludes an evidence-based approach to clinical management. We report a 23-year-old male with history of Type-IV Ehlers-Danlos Syndrome who presented with severe abdominal pain and tachycardia following an episode of vomiting. Further work-up of his abdominal pain revealed massive retroperitoneal bleeding by CT-scan of the abdomen. Given numerous cases of catastrophic injury caused by surgical intervention in Type-IV Ehlers-Danlos Syndrome, the patient was treated non-operatively, and the patient made a full recovery. This case suggests that even in cases of large retroperitoneal hemorrhages associated with Ehlers-Danlos Syndrome, it may not truly represent a surgical emergency. PMID:21966332

Idiopathic intracranial hypertension (IIH) in patients with Cushing disease (CD), after treatment, is rarely described, in adults. The cause is believed to be multifactorial, potentially related to a relative decrease in cortisol after surgical resection or medical treatment of a corticotroph pituitary adenoma. We investigate our center's CD database (140 surgically and 60 medically [primary or adjunct] treated patients) for cases of IIH, describe our center's experience with symptomatic IIH, and review treatment strategies in adults with CD after transsphenoidal resection. We present the case of a 22-year-old woman who presented with worsening headache, nausea, vomiting, blurry vision, diplopia, visual loss, and facial numbness 14 weeks after surgical resection of adrenocorticotropic hormone-positive pituitary adenoma. Her CD had been in remission since surgery, with subsequent adrenal insufficiency (AI), which was initially treated with supraphysiologic glucocorticoid replacement, tapered down to physiologic doses at the time the IIH symptoms developed. Symptomatic IIH is rare in adult patients but can be severe and result in permanent vision loss. A high index of suspicion should be maintained and a fundus examination is necessary to exclude papilledema, whenever there are suggestive symptoms that initially may overlap with AI. It is possible that some cases of mild IIH are misdiagnosed as GC withdrawal or AI; however, further studies are needed. Treatment consists of reinitiation of higher steroid doses together with acetazolamide with or without cerebrospinal fluid diversion and the priority is to preserve vision and reverse any visual loss.

We have been localizing pathological parathyroid glands by computed tomography(CT) since December '80. We reviewed 32 cases of surgically-treated hyperparathyroidism, in which 99 parathyroid glands were resected, each weight ranging from 20 to 3300 mg. Comparing the resected parathyroid glands with preoperative CT, we concluded as follows: 1) Pathological parathyroid glands were identified in 25 of the 32 cases (78 %). 2) In parathyroid glands weighing over 300mg, 60 from 64 glands (94 %) were identified by CT. 3) In secondary hyperaparathyroidism with radiologically proven subperiosteal resorption, pathologically-enlarged parathyroid glands were identified by CT in 22 from 23 cases (95%). CT was considered a useful diagnostic method in secondary hyperparathyroidism. 4) Experiencing 2 false-positive cases and one false-negative, which were ectopic cases, we concluded it necesary to use bolus-enhancement in localizing ectopic parathyroid glands.

In open bite case treatments, a proper diagnostic differentiation is essential in determining the appropriate corrective procedures. Dental open bites are generally more responsive to treatment with orthodontics alone, whereas skeletal open bites often require a combination of orthodontics and orthognathic surgery. Patient selection and treatment principles for non-surgical open bite treatment routinely include fixed appliances both labial or lingual. However, removable clear aligners have gained a consistent popularity in the treatment of complex cases including open bite malocclusions. In this article, the authors describe three different clinical cases in which open bite cases had been satisfactorily treated by using clear aligners.

Full Text Available Spinal deformity in patients with cystic fibrosis (CF is usually mild requiring no treatment. These patients are rarely considered as surgical candidates for scoliosis correction, as the pulmonary condition and other comorbidities increase the risk of general anaesthesia and recovery. This paper reviews all the literature up to date with regard to scoliosis in patients with CF and reports this unique case of a 14-year-old Caucasian girl with progressive scoliosis, who was treated surgically at the age of 17. She underwent a posterior spinal fusion T2-L3 with the use of unilateral segmental instrumentation. Preoperative workup included respiratory, cardiac, anaesthetic, endocrine, and dietician reviews, as well as bone density optimisation with zoledronic acid and prophylactic antibiotics. Surgical time was 150 minutes and intraoperative blood loss was 47% of total blood volume. Postoperative intensive care included noninvasive ventilation, antibiotic cover, pain management, chest physiotherapy, pancreatic enzyme supplementation, and nutritional support. She was discharged on day 9. At follow-up she had a good cosmetic outcome, no complaints of her back, and stable respiratory function. Multidisciplinary perioperative care and meticulous surgical technique may reduce the associated risks of major surgery in CF patients, while achieving adequate deformity correction and a good functional outcome.

Full Text Available OBJECTIVE Identify the direct cost of reprocessing double and single cotton-woven drapes of the surgical LAP package. METHOD A quantitative, exploratory and descriptive case study, performed at a teaching hospital. The direct cost of reprocessing cotton-woven surgical drapes was calculated by multiplying the time spent by professionals involved in reprocessing the unit with the direct cost of labor, adding to the cost of materials. The Brazilian currency (R$ originally used for the calculations was converted to US currency at the rate of US$0.42/R$. RESULTS The average total cost for surgical LAP package was US$9.72, with the predominance being in the cost of materials (US$8.70 or 89.65%. It is noteworthy that the average total cost of materials was mostly impacted by the cost of the cotton-woven drapes (US$7.99 or 91.90%. CONCLUSION The knowledge gained will subsidize discussions about replacing reusable cotton-woven surgical drapes for disposable ones, favoring arguments regarding the advantages and disadvantages of this possibility considering human resources, materials, as well as structural, environmental and financial resources.

Orthodontically induced iatrogenic root resorption (OIIRR) is an unavoidable inflammatory process. Several factors claimed to be related to the severity of OIIRR. Orthodontic forces cause micro-trauma to the periodontal ligament and activate a cascade of cellular events associated with local periodontal inflammation. The purpose of this split-mouth study were (1) to investigate the changes in cytokine profile in the gingival crevicular fluid (GCF) secondary to heavy orthodontic forces and (2) to compare the cytokine expression between participants showing high and low root resorption. Eight participants requiring maxillary first premolar extractions involved in this study. The teeth on the tested side (TS) received 225 g of controlled buccal tipping force for 28 days, while the contralateral teeth act as a control (CS). GCF was collected from both TS and CS teeth at 0 h (prior to application of force) and 3 h, 1 day, 3 days, 7 days and 28 days after the application of force, and analysed with multiplex bead immunoassay to determine the cytokine levels. Statistically significant temporal increase was found in the TS teeth for tumour necrosis factor alpha (TNF-α) at 3 h and 28 days (p = 0.01). Interleukin 7 (IL-7) significantly peaked at the 28th day. Comparing cytokine profile for participants with high and low root resorption (>0.35 and <0.15 mm 3 , respectively), the levels of GM-CSF was significantly greater in low root resorption cases (p < 0.05). The amounts of root resorption which craters on mesial, distal surfaces and middle third region were significant in the TS teeth (p < 0.05). IL-7 and TNF-α (pro-resorptive cytokine) increased significantly secondary to a high-level of orthodontic force application.

Duodenal diverticulitis has been considered a rare entity. The diagnosis with computed tomography has become a fast and noninvasive means of detection and guide to management. Cases of surgically resected duodenal diverticula reforming and reinfecting are rarer yet, often presenting with similar symptoms. Duodenal diverticulitis can present with a wide range of symptoms mimicking anything from gastritis to acute abdomen, or as in the case of our patient, as mid abdominal pain with newly developed liver abscess. According to the literature, duodenal diverticula are incidentally discovered at a rate of 5% to 10% in living adults and in up to 22% at autopsy.

The study started in September 1999 and ended in April 2002. It is based on a questionnaire [www.phidias.org] assessing case-related questions due to the application of stereolithographic models. Each questionnaire contains over 50 items. These variables take into account diagnosis, indications and benefits of stereolithographic models with view on different steps of the surgical procedures: preoperative planning, intraoperative application and overall outcome after surgical intervervention. These questionnaires were completed by the surgeons who performed operation. Over the time course of our multicentric study (30 months), we evaluated 466 cases. The study population consists of n=231 male and n= 235 female patients. 54 surgeons from 9 European countries were involved. There are main groups of diagnosis that related to the use of a model. Most models were used in maxillofacial surgery. The operative planning may help to determine the resection line of tumor and optimize reconstructive procedures. Correction of large calvarian defects can be simulated and implants can be produced preoperatively. Overall in 58 % of all cases a time- saving effect was reported. The study strongly suggests, that medical modeling has utility in surgical specialities, especially in the craniofacial and maxillofacial area, however increasingly in the orthopedic field. Due to our results, medical modeling optimizes the preoperative surgical planning. Surgeons are enabeled to perform realistic and interactive simulations. The fabrication of implants, its design and fit on the model, allow to reduce operation time and in consequence risk and cost of operation. In addition, the understanging of volumetric data is improved, especially if medical models are combined with standart imaging modalities. Finally, surgeons are able to improve communication between their patientents and colleagues.

Patient: Male, 30 Final Diagnosis: Acute epidural hematoma Symptoms: — Medication: — Clinical Procedure: Observation Specialty: Neurosurgery Objective: Unusual clinical course Background: Trauma is the leading cause of death in people younger than 45 years and head injury is the main cause of trauma mortality. Although epidural hematomas are relatively uncommon (less than 1% of all patients with head injuries and fewer than 10% of those who are comatose), they should always be considered in evaluation of a serious head injury. Patients with epidural hematomas who meet surgical criteria and receive prompt surgical intervention can have an excellent prognosis, presumably owing to limited underlying primary brain damage from the traumatic event. The decision to perform a surgery in a patient with a traumatic extraaxial hematoma is dependent on several factors (neurological status, size of hematoma, age of patients, CT findings) but also may depend on the judgement of the treating neurosurgeon. Case Report: A 30-year old man arrived at our Emergency Department after a traumatic brain injury. General examination revealed severe headache, no motor or sensory disturbances, and no clinical signs of intracranial hypertension. A CT scan documented a significant left fronto-parietal epidural hematoma, which was considered suitable for surgical evacuation. The patient refused surgery. Following CT scan revealed a minimal increase in the size of the hematoma and of midline shift. The neurologic examination maintained stable and the patient continued to refuse the surgical treatment. Next follow up CT scans demonstrated a progressive resorption of hematoma. Conclusions: We report an unusual case of a remarkable epidural hematoma managed conservatively with a favorable clinical outcome. This case report is intended to rather add to the growing knowledge regarding the best management for this serious and acute pathology. PMID:26567227

Full Text Available The aim of the study was to establish the frequency of some minor oral surgery performed on both teeth and on the soft tissues, before any orthodontic treatment. The sample group included 587 patients (240 boys and 347 girls, divided into 3 categories. The data base was created wtih patient records, the statistical analyses being performed with the SPSS 17.0 software for Windows. The frequency of malocclusions with minor oral surgery pretreatment orthodontics was of 24%, out of which the surgical interventions on teeth represented 85.41% (serial extractions – 21.87%, orthodontic extractions – 41.66%, enucleation of third molars – 18.75%, discovery of impacted teeth – 2.08% and teeth enucleation – 1.04% and the surgical interventions on the soft tissues represented 14.59% (labial frenectomy: 12.60%, lingual frenectomy: 1.04% and discovery of pericoronal tissues: 1.04% The minor oral surgery pretreatment orthodontics upon both teeth and soft tissues are not quite frequent, yet they are necessary for a partial preparation of the patient for orthodontic therapy.

In the last years, cardiovascular diagnosis, surgical planning and intervention have taken advantages from 3D modelling and rapid prototyping techniques. The starting data for the whole process is represented by medical imagery, in particular, but not exclusively, computed tomography (CT) or multi-slice CT (MCT) and magnetic resonance imaging (MRI). On the medical imagery, regions of interest, i.e. heart chambers, valves, aorta, coronary vessels, etc., are segmented and converted into 3D models, which can be finally converted in physical replicas through 3D printing procedure. In this work, an overview on modern approaches for automatic and semiautomatic segmentation of medical imagery for 3D surface model generation is provided. The issue of accuracy check of surface models is also addressed, together with the critical aspects of converting digital models into physical replicas through 3D printing techniques. A patient-specific 3D modelling and printing procedure (Figure 1), for surgical planning in case of complex heart diseases was developed. The procedure was applied to two case studies, for which MCT scans of the chest are available. In the article, a detailed description on the implemented patient-specific modelling procedure is provided, along with a general discussion on the potentiality and future developments of personalized 3D modelling and printing for surgical planning and surgeons practice.

Laparoscopic sleeve gastrectomy (LSG) is accepted as a stand-alone bariatric procedure. A specific and potentially severe complication of LSG is gastric stenosis (GS). Reviewing the treatment and prevention of GS after LSG. University hospital, Taiwan. A retrospective analysis was conducted involving all of the LSG cases (n = 927) at our institution between February 2007 and December 2015. Eight patients (0.8%) with GS were identified in our unit and 1 patient was transferred from another institution with symptomatic GS. The median intervals from initial LSG to the presence of symptoms, endoscopic dilation, and surgical revision were 14±30 days (range, 7-103 days), 21±35.6 days (range, 9-110 days), and 36±473.9 days (range, 11-1185 days), respectively. The majority of stenoses were located at the incisura angularis (8/9 [88.9%]). Among the 9 patients, only 1 responded satisfactorily to repetitive endoscopic dilation and the remaining 8 patients required revisional laparoscopic surgery, including conversion to Roux-en-Y gastric bypass (n = 6), stricturoplasty (n = 1), and Roux-en-Y gastric bypass after failed seromyotomy (n = 1). No patients experienced recurrent symptoms of GS after revisional surgery. In September 2013, we modified our surgical techniques for the subsequent 489 patients and GS did not occur after the change in surgical procedures. A combined treatment modality, endoscopic intervention with and without surgical revision is essential for managing GSs. Based on our own experience, we emphasize the clinical significance of surgical standardization to prevent the occurrence of GS. Copyright © 2016 American Society for Bariatric Surgery.

Full Text Available Introduction. Encapsulating peritoneal sclerosis (EPS is a clinical syndrome of progressive fibrotic change in response to prolonged, repetitive, and typically severe insult to the peritoneal mesothelium, often occurring in the setting of peritoneal dialysis (PD. Clear guidelines for successful management remain elusive. We describe the successful surgical management of EPS in a 28-year-old male s/p deceased donor kidney transplant for end-stage renal disease (ESRD secondary to focal segmental glomerulosclerosis (FSGS. This patient received PD for 7 years but changed to hemodialysis (HD in the year of transplant due to consistent signs and symptoms of underdialysis. EPS was visualized at the time of transplant. Despite successful renal transplantation, EPS progressed to cause small bowel obstruction (SBO requiring PEG-J placement for enteral nutrition and gastric decompression. The patient subsequently developed a chronic gastrocutaneous fistula necessitating chronic TPN and multiple admissions for pain crises and bowel obstruction. He was elected to undergo surgical intervention due to deteriorating quality of life and failure to thrive. Surgical management included an exploratory laparotomy with extensive lysis of adhesions (LOA, repair of gastrocutaneous fistula, and end ileostomy with Hartmann’s pouch. Postoperative imaging confirmed resolution of the SBO, and the patient was transitioned to NGT feeds and eventually only PO intake. He is continuing with PO nutrition, gaining weight, and free from dialysis. Conclusion. Surgical intervention with LOA and release of small intestine can be successful for definitive management of EPS in the proper setting. In cases such as this, where management with enteral nutrition fails secondary to ongoing obstructive episodes, surgical intervention can be pursued in the interest of preserving quality of life.

Although many older adults prefer to avoid burdensome interventions with limited ability to preserve their functional status, aggressive treatments, including surgery, are common near the end of life. Shared decision making is critical to achieve value-concordant treatment decisions and minimize unwanted care. However, communication in the acute inpatient setting is challenging. To evaluate the proof of concept of an intervention to teach surgeons to use the Best Case/Worst Case framework as a strategy to change surgeon communication and promote shared decision making during high-stakes surgical decisions. Our prospective pre-post study was conducted from June 2014 to August 2015, and data were analyzed using a mixed methods approach. The data were drawn from decision-making conversations between 32 older inpatients with an acute nonemergent surgical problem, 30 family members, and 25 surgeons at 1 tertiary care hospital in Madison, Wisconsin. A 2-hour training session to teach each study-enrolled surgeon to use the Best Case/Worst Case communication framework. We scored conversation transcripts using OPTION 5, an observer measure of shared decision making, and used qualitative content analysis to characterize patterns in conversation structure, description of outcomes, and deliberation over treatment alternatives. The study participants were patients aged 68 to 95 years (n = 32), 44% of whom had 5 or more comorbid conditions; family members of patients (n = 30); and surgeons (n = 17). The median OPTION 5 score improved from 41 preintervention (interquartile range, 26-66) to 74 after Best Case/Worst Case training (interquartile range, 60-81). Before training, surgeons described the patient's problem in conjunction with an operative solution, directed deliberation over options, listed discrete procedural risks, and did not integrate preferences into a treatment recommendation. After training, surgeons using Best Case/Worst Case clearly presented a choice between

Innominate artery (IA) aneurysms represent 3% of all arterial aneurysms. Due to the risk of thromboembolic complications and spontaneous rupture, surgical repair is usually recommended on an early elective basis. We present the case of 81-year-old Caucasian male presenting with atypical anterior chest pain secondary to a large innominate artery aneurysm who underwent successful open surgical repair at our institution. In our experience, open correction via median sternotomy with extension into the right neck provides excellent exposure and facilitates rapid reconstruction with good short and long-term outcomes. Minimally invasive and endovascular approaches provide emerging alternatives to open IA aneurysm repair, however further research is required to better define optimal patient selection criteria and determine the long-term outcomes of these novel therapies.

Full Text Available Combined fracture involving atlas together associated with axis (CAAF accounts for approximately 3 % of traumatic cervical spine injury, CAAF are rarely reported, so modalities of management and outcome are not well understood, due to paucity of literature and only few reports reported in the form of isolated case report. CAFF management possess challenge as it is associated with high incidence non-union with previously conservative method. However, missed diagnosis and subsequent delay may be associated with catastrophic worsening in neurological deficit. So early diagnosis and management remains the key for successful neurological outcome. Such fractures are rare. Authors report five such cases of CAFF, all required surgical management with good outcome with no mortality. Current study, all cases were males (n=5, commonest mode of injury was fall (n=3, time interval since injury was within 24 hours in (n=4, however rest one presented after a gap of eight months. Commonest clinical feature was neck pain (n=3, neurological deficit (n=2, neck tenderness and swelling tenderness (n=3 Neuroimaging including X-ray, CT scan and MRI were carried out for all cases revealed fracture of arches of atlas (n=5, one case had multiple site fracture of both arches, odontoid fracture (n=2, lateral mass of atlas fracture in 1 cases.

For years, the treatment for the replacement of a missing tooth was a fixed dental prosthesis. Currently, implants are indicated to replace missing teeth due to high clinical success and with the advantage of not performing preparations in the adjacent tooth. Another option for space closure is the use of orthodontics associated to miniscrews for anchorage allowing better control of the orthodontic biomechanics and especially making possible closure of larger prosthetic spaces. Thus, this article describes two cases with indications and discussion of the advantages and disadvantages of using orthodontics for prosthetic spaces closure. The cases herein presented show that it is possible to close an space when there are available teeth in the adjacent area. It can be concluded that when a malocclusion is present there will be a strong trend to indicate space closure by orthodontic movement as it preserves natural teeth and seems a more physiological approach.

Treatment of tibial stress fractures in elite dancers is centered on rest and activity modification. Surgical intervention in refractory cases has important implications affecting the dancers' careers. Refractory tibial stress fractures in dancers can be treated successfully with drilling and bone grafting or intramedullary nailing. Case series; Level of evidence, 4. Between 1992 and 2006, 1757 dancers were evaluated at a dance medicine clinic; 24 dancers (1.4%) had 31 tibial stress fractures. Of that subset, 7 (29.2%) elite dancers with 8 tibial stress fractures were treated operatively with either intramedullary nailing or drilling and bone grafting. Six of the patients were followed up closely until they were able to return to dance. One patient was available only for follow-up phone interview. Data concerning their preoperative treatment regimens, operative procedures, clinical union, radiographic union, and time until return to dance were recorded and analyzed. The mean age of the surgical patients at the time of stress fracture was 22.6 years. The mean duration of preoperative symptoms before surgical intervention was 25.8 months. Four of the dancers were male and 3 were female. All had failed nonoperative treatment regimens. Five patients (5 tibias) underwent drilling and bone grafting of the lesion, and 2 patients (3 tibias) with completed fractures or multiple refractory stress fractures underwent intramedullary nailing. Clinical union was achieved at a mean of 6 weeks and radiographic union at 5.1 months. Return to full dance activity was at an average of 6.5 months postoperatively. Surgical intervention for tibial stress fractures in dancers who have not responded to nonoperative management allowed for resolution of symptoms and return to dancing with minimal morbidity.

Gross hip instability is a rare complication after hip arthroscopy, and there is limited literature surrounding this topic. This systematic review investigates cases of gross hip instability after arthroscopy and discusses the risk factors associated with this complication. A systematic search was performed in duplicate for studies investigating gross hip instability after hip arthroscopy up to October 2015. Study parameters including sample size, mechanism and type of dislocation, surgical procedure details, patient characteristics, postoperative rehabilitation protocol, and level of evidence were analyzed. The systematic review identified 9 case reports investigating gross hip instability after hip arthroscopy (10 patients). Anterior dislocation occurred in 66.7% of patients, and most injuries occurred with a low-energy mechanism. Common surgical factors cited included unrepaired capsulotomy (77.8%) and iliopsoas release (33.3%), whereas patient factors included female gender (77.8%), acetabular dysplasia (22.2%), and general ligamentous laxity (11.1%). Postoperative restrictions and protocols were variable and inconsistently reported, and their relation to post-arthroscopy instability was difficult to ascertain. This systematic review discussed various patient, surgical, and postoperative risk factors of gross hip instability after arthroscopy. Patient characteristics such as female gender, hip dysplasia, and ligamentous laxity may be risk factors for post-arthroscopy dislocation. Similarly, surgical risk factors for iatrogenic hip instability may include unrepaired capsulotomies and iliopsoas debridement, although the role of capsular closure in iatrogenic instability is not clear. The influences of postoperative restrictions and protocols on dislocation are also unclear in the current literature. Surgeons should be cognizant of these risk factors when performing hip arthroscopy and be mindful that these factors appear to occur in combination. Level IV

Polyarteritis nodosa (PAN) is a primary systemic necrotizing vasculitis with diffuse organ involvements, resulting in a high mortality rate due to multiple organ failure. Although the small bowel is the frequently targeted organ of PAN-associated vasculitis, rectal involvement is very rare, and only one case of rectal bleeding has been previously reported. The mortality rate of PAN with gastrointestinal (GI) perforation is reportedly much higher than that of without severe GI involvement. We herein report the first case of rectal perforation due to PAN, successfully managed with an adequate surgical intervention. A 66-year-old woman with PAN had abdominal pain and melena with guarding. Computed tomography scan showed abdominal free air and bubbles in the rectal hematoma. We diagnosed it acute peritonitis, and emergency surgery was performed. After removing rectal hematoma and necrotic tissue, a huge lack of rectal wall spreading to the pelvirectal space was observed. In order to totally remove the necrotic tissue, abdominoperineal resection was needed. Together with histopathological examinations which showed neutrophils and fibrinous necrosis, we finally diagnosed rectal perforation due to PAN. At 19-month follow-up after surgery, she was still healthy with a stable disease of PAN. We herein reported the first case of successfully managed rectal perforation due to PAN. Early adequate surgical resection may be important for the case with rectal perforation.
Full Text Available Introduction: Accomodative esotropia is secondary to inappropriate convergence during accomodative effort in an uncorrected hyperope and is often familial. Case presentation: we report the case of 20 year old Caucasian patient with congenital esotropia alternating, of 30 prism diopters distance (5 m and 40 prism diopters of esotropia at near, in both eyes. Measures: Was performed strabismus, in peribulbar anesthesia, the right medial rectus was cashed 3.0mm, the left medial rectus was collected 3.5 mm. Results: Immediately after surgery, the patient complained of intermittent diplopia, resolved with orthotic exercise which stimulated binocular vision, Conclusion: This case report suggests that the surgical correction strabismus, should be considered with due caution in the treatment of congenital esotropia alternating and branches, and in some clinical scenarios selected to avoid the complication of postoperative diplopia, that in the case report resolved so benign. After three months surgical treatmen, remains a small angle strabismus aesthetically acceptable, has not given double vision and remains abnormal retinal correspondence with orthotic exercise.

Surgical meshes are widely used in incisional hernia repair. However, there are no reports of pregnancies complicated by infection of surgical meshes used for hernia repair. This is the first case report of a pregnant woman who experienced surgical site infection associated with surgical mesh used for repair of an abdominal wall incisional hernia. We report a case of a 41-year-old pregnant Japanese woman with surgical site infection after mesh repair of an abdominal wall incisional hernia. She was diagnosed with an abdominal wall incisional hernia at 3 months after her third cesarean section, and she underwent an operation of hernia repair with use of monofilament polypropylene mesh 7 months after the third cesarean section. However, a surgical site infection associated with surgical mesh occurred. During antibiotic treatment, she was found to be pregnant. She was referred to our hospital at 13 weeks and 2 days of gestation. The surgeons removed the infected mesh at 16 weeks and 3 days of gestation. Neither the hernia nor infection at the surgical site recurred throughout pregnancy. We planned a cesarean section using a transverse uterine fundal incision method with an upper abdominal incision. The patient delivered a 2478-g healthy female infant. The present report shows that removal of mesh can safely control surgical site infection during pregnancy.

Cubital tunnel syndrome (CuTS) is a frequent neuropathy, leading to sensor-motoric dysfunction. Many patients even present with muscular atrophy as a sign for severe and long-lasting nerve impairment, usually suggesting unfavourable outcome. We analysed if those patients benefit from surgical treatment on a long-term basis. Between January 2010 and March 2015, 42 consecutive cases of CuTS with atrophy of the intrinsic hand muscles were surgically treated in our department. Clinical data of the treatment course and postoperative results were collected. Follow-up was prospectively assessed according to McGowen grading and Bishop outcome score. Mean follow-up time was 39.8 (±17.0) months. All patients were treated with in situ decompression; in 33%, submuscular transposition was performed. Forty-five percent showed improvement of sensory deficits and 57% showed improvement of motor deficits 6 months after the operation. Atrophy improved in 76%. At the time of follow-up, 79% were satisfied with the postoperative result and 77% of patients reached good or excellent outcome according to modified Bishop rating scale. Patients with improvement of atrophy had significantly shorter symptom duration period (7 ± 10 months vs 26 ± 33 months; p atrophy improvement was less likely (p atrophy of the intrinsic hand muscles, surgical treatment enables improvement of sensory function, motor function and atrophy even in cases with muscular atrophy. Atrophy improvement was more likely in cases of short symptom duration and less likely in cases with pseudoneuroma.

Grisel syndrome is a nontraumatic rotatory subluxation of the atlantoaxial joint, following nasopharyngeal inflammation or ear, nose, and throat (ENT) procedures. The syndrome should be suspected in cases of persistent neck pain and stiffness, especially after ENT surgical procedures. The primary treatment of early detected Grisel syndrome is conservative. If conservative treatment fails to achieve a stable reduction or it is followed by neurologic symptoms, arthrodesis of the first and second cervical vertebrae is indicated. We report the case of a 9-year-old boy who developed Grisel syndrome after adenoidectomy and was treated with C1-C3 internal fixation and fusion. A 9-year-old boy was referred to our hospital with a 3-month history of painful torticollis, which appeared 4 days after adenoidectomy. The patient underwent a neuroimaging study that documented the presence of atlantoaxial rotatory subluxation. The patient underwent C1-C3 internal fixation and fusion, using lateral masses and laminar and pars interarticularis screws. On the third postoperative day he was mobilized with a rigid collar. Postoperative computed tomography scans showed the resolution of rotational deformity and a solid fusion. Early treatment of Grisel syndrome is of utmost importance to avoid neurologic complications and surgical intervention. In a patient with torticollis following ENT procedures, Grisel syndrome should be always suspected. In case of failure of conservative treatment or in case of delayed diagnosis, rigid C1-C2 or C1-C2-C3 fixation is a straightforward and valid surgical technique, even in children, because it provides immediate spinal stability in all planes at the atlantoaxial complex, avoiding the need for prolonged rigid external bracing.

A dental movement during an orthodontic treatment may generate an inflammatory or degenerative response on pulp tissue. As this tissue exposed to a mechanical load under different magnitude, frequency and length, it expresses both macroscopic and microscopic changes by induction of circulatory and vascular changes. However, most cases the pulp tissue has a tendency to recover itself keeping its structure and function. It has therefore been suggested that injury upon pulp produced by orthodont...

Full Text Available Abstract Introduction Treatment for osteomyelitis-complicating Mycobacterium ulcerans infection typically requires extensive surgery and even amputation, with no reported benefit from adjunctive antibiotics. Case presentation We report a case of an 87-year-old woman with M. ulcerans osteomyelitis that resolved following limited surgical debridement and 6 months of therapy with rifampicin and ciprofloxacin. Conclusion M. ulcerans osteomyelitis can be successfully treated with limited surgical debridement and adjunctive oral antibiotics.
This case report analyzes long-term occlusal stability that can be achieved in Class II, Division 1, deep bite cases with active treatment finished during the period of maxillomandibular growth. The analysis was designed to identify occlusal features common to two cases at the end of active treatment and to study how the occlusion changed with growth and jaw movement to achieve stability. The following occlusal features were shared by the two cases at the end of active treatment: (1) AB plane and axes of the maxillary and mandibular posterior teeth were perpendicular to functional occlusal plane; (2) the axis of the lower incisor was almost perpendicular to DC-L1i line; (3) the anterior occlusion was overcorrected to or near an edge-to-edge relationship. Items 1 and 2 remained unchanged throughout the follow-up periods, regardless of growth status, and the overjet and overbite increased during maxillomandibular growth after treatment. During the period of mandibular growth alone, after the end of retention, the axes of maxillary incisors tipped labially; as a result, F line became parallel to CDM line by the end of growth. The labial tipping of maxillary incisors brought the lower incisal edge into contact with or extremely near the inflection point (Bp).1 By the end of growth, the tangent of Bp became parallel to or coincident with DC-L1i line and perpendicular to the axis of the lower incisor, and the DC-L1i lines at various times posttreatment were almost parallel to each other in the two cases. Overjet increased as the maxillary incisors tipped labially, providing proper protrusive and retrusive paths for mandibular guidance. The angle between the functional occlusal plane and CDM line stayed almost the same as at the end of active treatment in the two cases, suggesting a possible change in the angle of eminence in harmony with the functional occlusal plane. These factors apparently contributed to the long-term occlusal stability in the two cases.
Traumatic tooth fractures, dental caries, and overzealous tooth preparations can lead to the loss of coronal tooth structure, thus complicating the definitive prosthetic plan. Although exposure of additional clinical tooth structure by surgical crown lengthening is often recommended, such an approach is usually discouraged because of the possible adverse periodontal changes to the adjacent teeth and compromised esthetics, especially in the presence of an otherwise intact arch. This article discusses the application of orthodontic extrusion to conservatively restore a single tooth with minimal coronal tooth structure in the esthetic zone. A detailed description of the prosthetic approach used before, during, and after orthodontic therapy is presented.
Full Text Available Pes cavus is a deformity of the foot characterized by an abnormally increased arch and hyperextension of the toes that gives the foot the appearance of a claw. We encountered a case of a 54-year-old male patient who presented with total right foot amputation due to injury with the tea harvesting engine. During physical examination, we observed a right foot amputation in the level of the metatarsophalangeal area and a bilateral idiopathic pes cavus deformity. In this unusual case, we aimed to report the difficulties experienced in bone stabilization and tendon repair, which are the first steps in limb replantation, and the tendon lengthening technique used to correct the pes cavus deformity, which is a novel technique for this deformity, along with a review of the related literature. The surgical outcomes of the case were successful.

Multilevel lumbar spondylolysis accounts for less than 6% of the cases of lumbar spondylolysis and its treatment, as reported in the literature, has not been consistent. Fewer than ten cases presenting triple lumbar spondylosis have been published. We describe the case of a 33-year-old male presenting bilateral L3, L4, and L5 isthmic lysis with no spondylolisthesis or disc degeneration. The MRI and CT of the lumbar spine were decisive elements in the therapeutic choice and the surgical treatment performed was bilateral L3 and L4 isthmic repair via a combined anterior and posterior L5S1 approach. The clinical and radiological results were good at the last follow-up visit. Copyright © 2014 Elsevier Masson SAS. All rights reserved.
Cardiac myxoma is the most common primary cardiac tumour, but infected cardiac myxoma is relatively rare. Infected cardiac myxoma is very fragile, and has a potential to lead to catastrophic disorder with systemic bacteremia, systemic mycotic embolism, and disseminated intravascular coagulation (DIC). We present here the successful surgical treatment of a case of infected left atrial myxoma with septic shock, DIC and cerebral infarction without hemorrahage. Collective review of 58 reported cases with infected cardiac myxoma revealed that surgical treatment for it were still challenging and its result was poor. Until date, only one successful surgical treatment for a case complicated by DIC and cerebral infarctions has been reported, and our report describes second such case of successful resection. Even though this report is limited to a case, only aggressive and prompt surgical intervention could relieve the intractable conditions in such a patient with extremely high risk. PMID:21569401

A caecal appendix within an inguinal hernia, with or without appendicitis, is defined as Amyand's hernia. In 1% of inguinal hernias an appendix without inflammation can be found, however, the prevalence of appendicitis in a hernia sac is only 0.08-0.13%. Male of 43 years old, began two days before admission with pain in the right inguinal region. He was scheduled for surgery due to a complication of a right inguinal hernia. The surgical findings were Amyand's hernia, necrotic spermatic cord, and perforated appendix. Surgical repair was performed with a favourable outcome, and he was discharged on the fourth postoperative day. Most of Amyand's hernia exhibit characteristics of incarcerated or strangulated inguinal hernia. Even acute appendicitis or perforated appendix within the hernia sac does not reflect specific symptoms or signs, therefore, a preoperative clinical diagnosis of Amyand's hernia is difficult to achieve. In our case, the patient had perforated appendicitis, developing necrosis of the spermatic cord. Orchiectomy, appendectomy, and inguinal hernia repair was performed without placing mesh. Due to the controversy on the use of mesh in contaminated abdominal wall defects, it was not indicated here, due to the high risk of wound infection and appendicular fistula. An extremely rare condition is presented, with a surgical choice that led to a favourable outcome. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A.

Full Text Available Introducation: The long-term outcome and clinical results of gaparthroplasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared. The purpose of this study was to compare the effect of gap arthroplasty and costochondral graft methods on reankylosis, a mount of mouth opening and growth. Materials and Methods: A non-randomized, retrospective clinical study of l0 cases (5-12 years old of condylar ankylosis of the mandible, surgically treated during a 10 year period from 2002 to 2012 was performed. Four patients were treated by condylectomy and interpositional flap, whereas six were treated by condylectomy and immediate costachondral rib grafts. The first group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, and computed tomography (CT were used post surgically to evaluate rib graft, condylar growth and function, occlusion, facial, and condylar symmetry. Data were analyzed by SPSS 16 statistical software using Mann-Whitney, Paired T-test and Chi-square tests. Results: Children with long-standing condylar ankylosis of the mandible treated by condylectomy and interpositional flap showed more favorably when activators were used post-surgically. Conclusions: Gaparthroplasty with functional activator post-operatively can be considering for TMJ ankylosis.
Full Text Available Case report of a 54-year-old patient, with no complaints and noalterations detected during the physical examination, who underwenta routine pelvic ultrasound that showed a complex cyst on the rightovary which was confirmed with a CT scan. The serum CA125 levelwas elevated while other tumor markers – carcinoembryonic antigen,alphafetoprotein antigen and the beta human chorionic gonadotrophinwere normal. Videolaparoscopy was used for the diagnosis andtherapeutic management, revealing vegetating lesions on bothovaries but no other alterations. Biopsies were performed on thetumor masses and analyzed using the frozen section technique duringthe surgical procedure which revealed a serous neoplasm of lowmalignant potential - borderline. Next, ovarian carcinoma stagingwas performed in accordance with the standards recommended bythe International Federation of Gynecology and Obstetrics: bilateralsalpingo-oophorectomy, total abdominal hysterectomy, bilateralpelvic and para-aortic lymphadenectomy. To complete the staging,an omentectomy was performed by means of a 4 cm transverseincision in the epigastric region which was enlarged using a specialDexterity Protractor™retractor. The incision also enabled the removalof surgical specimens. The patient was discharged from the hospitalon the following day and recovered without any complications.Histological analysis confirmed the borderline tumor and no malignantcells were found on the other surgical specimens. Videolaparoscopy,minilaparotomy and the special retractor enabled adequate diagnosis,staging and removal of the localized ovarian tumor.

Full Text Available Case description: A 60 year old female patient presented to Department of Prosthodontics, CODS, BPKIHS, Dharan with a chief complain of loose obturator. History revealed that patient had undergone partial maxillectomy for squamous cell carcinoma 7 years back. The patient also has been wearing obturator which was loose when the patient reported to the department. On examination, the site of surgery was the maxillary right buccal sulcus area and a part of the hard palate including teeth number 11, 12, 13, 14, 15, 16, 17. The presented defect situation corresponded to a Class I situation (resection performed along the palatalmidline according to the Aramany classification of defects. The surgical site showed complete healing. A hollow-bulb obturator was fabricated for rehabilitation of the defect. Conclusion: The extensive surgical procedures necessary to eradicate cancer of the head and neck and to prevent local recurrence or regional metastasis often leave extremely large physical defects which present almost insurmountable surgical difficulties in restoring acceptable function or esthetics. The prosthesis rehabilitated the patient in terms of function by providing better masticatory efficiency, phonetics by adding resonance to the voice, hence improving the clarity of speech and also improved the esthetics of the patient.

Enterococcal post-surgical meningitis is an uncommon disease. 20 episodes of nosocomial post-surgical enterococcal meningitis diagnosed between 1994 and 2003 were retrospectively studied. During the period of study 20 cases of post-surgical enterococcal meningitis (60% female, mean age 55+/-18 y, range 16-78 y) were reviewed. The mean time between admission at the hospital and surgery was 26 (SD = 15) d (range 7-61 d). The most frequent underlying diseases were: intracerebral haemorrhage (55%), brain neoplasms (25%), head trauma (15%) and hydrocephalus (5%). 11 patients had previously received antibiotic treatment. The isolates identified were Enterococcus faecalis (n = 18) (90%), E. faecium (1) and E. durans (1). 11 patients had polymicrobial infections. The treatment most frequently used was vancomycin alone or with other antibiotics (11). In 5 patients intrathecal vancomycin (20 mg/d) was also added. The mortality rate was not different in intrathecally treated patients. Cerebrospinal fluid (CSF) devices were removed in 8 patients. Four patients died due to the infection. Mortality was significantly associated with lack of removal of the CSF devices (p = 0.04). Enterococcal spp. are a cause of nosocomial meningitis associated with neurosurgical procedures and the presence of neurological devices.

Full Text Available Long-face cases usually need both treatment of orthodontic and surgery. The problem appearing in the correction of long-face might be able to be related with some difficult factors such as the crowded teeth and excessive vertical height. A class III malocclusion and excessive open bite can be also followed in long face. This situation might worsen the facial aesthetic condition and increase the difficulty in orthodontic treatment. The orthodontic approach is oriented toward positioning the teeth pre-surgically to facilitate the surgical plan. The form of mandible which has grown in the downward direction in the area of mandible angle makes an extreme vertical open bite. The maxilla is usually presented with a maxillary hypolasia. Double-jaw surgery was done as the correction of the lower jaw alone would produce a flattened face appearance and difficulty in repositioning the mandible to achieve a good facial performance. Several cephalometric points were measured to observe the facial situation progress after surgery. Two cases of longface are reported, and the same surgical treatments were performed and showed different results.
Full Text Available Introduction: Subcutaneous emphysema (SE is a frequent and often self-limiting complication of tube thoracostomy or other cardiothoracic procedures. On rare occasions, severe and extensive surgical emphysema marked by palpable cutaneous tension, dysphagia, dysphonia, palpebral closure or associated with pneumoperitoneum, airway compromise, “tension phenomenon” and respiratory failure require treatment. Presentation of case: A 67 year old lady presented with a large spontaneous pneumothorax on the background of end-stage chronic obstructive pulmonary disease (COPD and newly diagnosed lung cancer, developed extensive surgical emphysema following insertion of a chest drain. Immediate improvement was observed after insertion of a large-bore, 26 French (Fr. intercostal catheter, subcutaneous drain which was maintained under low suction (−5 cm H2O for a further 24 h. Discussion: Several methods have been described in the literature for the treatment of extensive subcutaneous emphysema, including: emergency tracheostomy, multisite subcutaneous drainage, infraclavicular “blow holes” incisions and subcutaneous drains or simply increasing suction on an in situ chest drain. Here a large-bore, fenestrated, subcutaneous drain maintained on low negative pressure also provided the necessary decompression. Conclusion: In the absence of a comparative study to identify the most effective method to manage extensive subcutaneous emphysema, this case highlights an effective, simple and safe management option.

Full Text Available Introduction: The imaging method of cone beam is an improved, extremely accurate computed tomography applicable in the whole field of dentistry. Due to its ability to locate the exact position of the impacted teeth, CBCT software has an important role in the management of difficult cases of impacted third molar. In some situations, the lower third molar is quite near to the inferior alveolar nerve that the surgical extraction can present a high risk of post-operative sensitive impairs of the skin and mucosa of the lower lip and chin on the same side. Presentation of case series: Our study tried to assess the contribution of CBCT in the pre-operative evaluation and further treatment of patients with impacted third molars in mandibular bone with high risk of inferior alveolar nerve injury. The paper presents three clinical cases showing positive signs on standard OPG, which exhibit indicators of a potential contact between the inferior alveolar nerve and the impacted lower third molars. For an improved exploration Dental CT Scan, DICOM image acquisition program, and 3D reconstruction with a special software were used. Conclusions: The study showed that compared with panoramic radiography, CBCT improve the evaluation of the surgical risk and allow a more accurate planning of surgery.

Subungual melanoma (SUM) is a rare entity, comprising approximately 0·7-3·5% of all melanoma subtypes. SUM histopathologically belongs to the acral lentiginous pathological subtype of malignant melanoma. Its diagnosis is helped by dermoscopy but pathological examination of doubtful cases is required. Classical management of SUM is based on radical surgery, namely distal phalanx amputation. Conservative treatment with nonamputative wide excision of the nail unit followed by a skin graft has been insufficiently reported in the medical literature even though it is performed in many centres. To report a series of patients with in situ or minimally invasive SUM treated by conservative surgery, to investigate the postoperative evolution and to evaluate the outcome with a review of the literature. We performed a retrospective extraction study from our melanoma register of all patients with in situ and minimally invasive SUM treated with conservative surgery in the University Hospital Department of Dermatology, Lyon, France from 2004 to 2009. The patient demographics, disease presentation, delay to diagnosis, histopathology and postoperative evolution were reviewed. Seven cases of SUM treated as such were identified in our melanoma database. All cases had a clinical presentation of melanonychia striata. The mean delay to diagnosis was 2years. Surgical excision of the entire nail unit with a 5-10mm safety margin without bone resection followed by full-thickness skin graft taken from the arm was performed in all cases. No recurrence was observed with a mean follow-up of 45months. Functional results were found satisfactory by all patients and their referring physicians. Sixty-two other cases have been found in the literature and are also discussed. Conservative surgical management in patients with in situ or minimally invasive SUM is a procedure with good cosmetic and functional outcome and, in our cases as well as in the literature, the prognosis is not changed. © 2011

Full Text Available Malignant neoplasms occurring from the trachea are extremely rare. Therefore, their clinical characteristics and surgical results have not been thoroughly discussed. These tumors are often misdiagnosed and treated as bronchial asthma or chronic obstructive pulmonary disease. It is critically important to probe the cause-effect relationship between the medical presentations and the clinical diagnosis. In this report, two cases of tracheal malignancy suffering from dyspnea due to obstruction of the proximal trachea are described, and a review of the literature is presented.

We report a case of radiation gastritis in consequence of radiotherapy for recurrent ovarian cancer. A 61-year-old woman received irradiation of a metastatic lesion of the second lumbar vertebra. Six months later she complained of fatigue and presented with severe anemia, and her diagnosis was hemorrhagic radiation gastritis. She was treated endoscopically, but that failed to control the bleeding, making it necessary to resect surgically. The incidence of radiation gastritis is very low because the stomach is rarely within the treated field, but it is of importance to be aware that the stomach is by no means more radioresistant than other organs.

Rehabilitation of esthetics in advanced periodontal cases using orthodontics for vertical hard and soft tissue regeneration prior to implants - a report of 2 challenging cases treated with an interdisciplinary approach.
Mankoo, Tidu; Frost, Laura
The esthetic rehabilitation of advanced periodontal cases remains a challenge, despite the numerous advances in treatment of periodontitis and regenerative therapies. Whilst understanding of periodontal diseases deepens with advances in cell biology, cell signaling, and genomic research, the restoration of the gingival tissues to anatomical norms remains a considerable challenge in advanced cases. The improvements in diagnosis and treatment of disease certainly enable successful management of disease and stabilization of the compromised and failing dentition. Nonetheless, effective "esthetic" rehabilitation of patients with advanced disease affecting teeth in the esthetic zone, where significant asymmetrical bone loss and tissue recession are present, still constitutes a significant dilemma. An interdisciplinary approach involving vertical augmentation of bone and soft tissues by means of orthodontic extrusion of severely compromised periodontally involved teeth to reconstitute esthetics, as well as ideal bone and soft tissue volume prior to immediate implant placement and restoration, may be a particularly useful treatment option in patients suffering advanced periodontal disease with asymmetrical bone and tissue loss in the esthetic zone. This paper discusses the concepts and illustrates its use in two complex and demanding cases.

To investigate the clinical manifestation and surgical outcome of spinal osteoblastoma. From June 2006 to July 2011, 18 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 11 males and 7 females with an average age of 27.5 years（range, 16-38 years). The tumors were located at C5 in 7, C6 in 6, C7 in 3, C6-T1 1 in 1 and T11 in 1. Based on WBB classification, 16 were 1-3 or 10-12 and 2 were 4-9 and 1-3. 18 operations had been performed with en bloc resection. A posterior approach was used for 16 patients, and a combined posterior and anterior approach was used for 2 patients. Reconstruction using instrumentation and fusion was performed using spinal instrumentation in 13 patients. We used visual analogue scales (VAS) to evaluate the change of pain before and after the operation, and the McCormick System to assess functional status of the spine. Imaging test was used to review the stability and recurrence rate of spine cord, and the confluence of graft bones. All cases were followed up for 24-80 months (average, 38.4 months). The average surgical time was 120.8 minutes (range, 80-220 minutes), with the average intraoperative blood loss of 520 ml (range, 300-1200 ml). During the follow-up period, the VAS grade reduced from 6.46±1.32 to 2.26±1.05 (P osteoblastoma has its own specific radiographic features. There is some recurrence in simple curettage of tumor lesion. The thoroughly en bloc resection of tumor or spondylectomy, bone fusion and strong in Ter fixation are the key points for successful surgical treatment.

Since the introduction of lasers in dentistry in the mid-1990's, research in laser supported dental therapies is progressing at a rapid pace. Orthodontics is no exception. In orthodontics, lasers have many diagnostic, therapeutic, and biomodulating applications. To update the various applications of lasers in orthodontics. Lasers work by delivering energy in the form of light. Laser, striking the biological tissues can either get reflected, absorbed or scattered depending on several factors. Depending on the fate of the emitted laser, it can be applied for different diagnostic, therapeutic and surgical procedures. The knowledge and understanding of different types of lasers and its specific applications is a prerequisite before it can be applied beneficially. In Orthodontics, the versatility of laser has expanded into bonding, curing, debonding, imaging, growth modification, pain reduction, etc. Definitely laser has extended its tentacles from diagnosis to treatment in orthodontics.
Full Text Available Abstract Our aim was to discuss, by presenting a case, the possibilities connected to the use of a CBCT exam in the dental evaluation of patients with Cleidocranial Dysplasia (CCD, an autosomal dominant skeletal dysplasia with delayed exfoliation of deciduous and eruption of permanent teeth and multiple supernumeraries, often impacted. We think that CBCT in this patient was adequate to accurately evaluate impacted teeth position and anatomy, resulting thus useful both in the diagnostic process and in the treatment planning, with an important reduction in the radiation dose absorbed by the patient.
Introduction: In orthodontics, is quickly increasing the demand for treatments with a very low aesthetic impact in the social life. More and more adult patients want satisfy their necessity to have a beautiful smile, with “invisible” appliances. Numerous are the opportunities to perform an aesthetic orthodontic treatment such as lingual orthodontics, clear aligners or clear labial orthodontics. Aesthetic orthodontic archwires are a component of clear labial orthodontics together with aestheti...

Full Text Available Abstract Background The hierarchical nature of medical education has been thought necessary for the safe care of patients. In this setting, medical students in particular have limited opportunities for experiential learning. We report on a student-faculty collaboration that has successfully operated an annual, short-term surgical intervention in Haiti for the last three years. Medical students were responsible for logistics and were overseen by faculty members for patient care. Substantial planning with local partners ensured that trip activities supplemented existing surgical services. A case review was performed hypothesizing that such trips could provide effective surgical care while also providing a suitable educational experience. Findings Over three week-long trips, 64 cases were performed without any reported complications, and no immediate perioperative morbidity or mortality. A plurality of cases were complex urological procedures that required surgical skills that were locally unavailable (43%. Surgical productivity was twice that of comparable peer institutions in the region. Student roles in patient care were greatly expanded in comparison to those at U.S. academic medical centers and appropriate supervision was maintained. Discussion This demonstration project suggests that a properly designed surgical trip model can effectively balance the surgical needs of the community with an opportunity to expose young trainees to a clinical and cross-cultural experience rarely provided at this early stage of medical education. Few formalized programs currently exist although the experience above suggests the rewarding potential for broad-based adoption.
Full Text Available We report a case of a 51 years old female with a 25 pack year smoking history who underwent bilateral mastectomy and immediate tissue expander reconstruction for newly diagnosed right breast cancer. The patient reported herself as a non-smoker despite significant e-cigarette use, with resulting significant mastectomy skin flap necrosis and breast reconstruction failure. Little is known about the physiologic effect of e-cigarettes on wound healing and tissue perfusion. To this end, we provide an updated review of the impact of e-cigarettes on surgical outcomes. PubMed, Ovid MEDLINE, and PRS GO were searched for the terms “e-cigarette”, “electronic cigarette”, “e-cig”, “electronic nicotine delivery system”, “vaping”, “surgery”, “surgical”, “peri-operative”, “operate”, “operative”, and “wound healing”. Abstract review of all articles was performed. 123 articles returned that contained both variants of e-cigarettes and surgery as keywords. Of those, manual assessment returned three articles which were found to be relevant to e-cigarette use in the surgical patient. No articles were found that compared perioperative complications in e-cigarette versus traditional cigarette users in humans. In conclusion, our case report depicts the potential dangers associated with e-cigarette use in the surgical patient. There is a public misconception that e-cigarettes are healthier than traditional cigarettes and as such their use may go unreported by patients. Early evidence suggests e-cigarettes may induce some of the same physiologic changes as traditional cigarettes, and may have a significant deleterious effect on wound healing.

Recent literature strongly challenged indications to perform preventive surgery in unruptured arteriovenous malformation (AVM) claiming that invasive AVM treatment is associated with a significant risk of complications and thus conservative management may be a preferable alternative in many patients. On the other hand, the recent improvement of surgical instrumentation and treatment strategies (both surgical and interventional) yielded better outcomes than those achieved only a decade ago. Therefore, even among specialists, a wide variety of opinions, concerning the treatment of unruptured AVM, can be found. This multicenter retrospective study analyzes a consecutive series of 545 surgically treated AVMs in 10 different hospitals in Italy. Patients with AVMs treated after hemorrhage had an unfavorable (modified Rankin Scale score >1) outcome in more than one third (37.69%) of the cases. Conversely, with proper indications, unruptured AVMs treated preventively have a good outcome in 93.8% of cases, increasing to 95.7%, with no death, if only Spetzler-Martin grades 1-3 are considered (P < 0.05). Outcomes on discharge significantly (P < 0.05) improve at 6 months with the disappearance of many of the initial neurologic deficits that turn out to be transient. In unruptured low-risk AVMs (Spetzler-Martin grades 1-3), over time, the risk of surgery-associated neurologic deficits becomes lower than that linked to spontaneous hemorrhage, with a crossover point at 6.5 years. Because the average bleeding age is less than 45 years, preventive surgery can be advocated to safeguard the patient and overcome the risks associated with the natural history of AVMs. Copyright © 2017 Elsevier Inc.

Piezocision-assisted orthodontic treatment is an innovative, minimally invasive surgical technique designed to help achieve rapid orthodontic tooth movement. Microsurgical interproximal openings are made in the buccal gingivae to let the piezoelectric knife create the bone injury that will lead to transient demineralization and subsequent accelerated tooth movement. When this procedure was first described, cuts were made simultaneously at the maxilla and the mandible. In recent years, the technique has evolved to a more staged approach, with selected areas or segments of the arch demineralized at different times during orthodontic treatment to help achieve specific results. The purpose of this article was to report the use of sequential piezocision in the correction of a Class III malocclusion, in a total treatment time of 8 months.

An increasing number of adult patients have been seeking orthodontic treatment, and a short treatment time has been a recurring request. To meet their expectations, a number of surgical techniques have been developed to accelerate orthodontic tooth movement. However, these have been found to be quite invasive, leading to low acceptance in patients and the dental community. The authors are introducing a new, minimally invasive procedure, combining microincisions with selective tunneling that allows for hard- or soft-tissue grafting and piezoelectric incisions. This novel approach is leading to short orthodontic treatment time, minimal discomfort, and great patient acceptance, as well as enhanced, or stronger, periodontium. Because of the added grafting (bone and/or soft tissue), the periodontium is much thicker buccally.
Full Text Available The purpose of this review is to investigate the current evidence and implications of lingual orthodontics. The electronic database search was done on PubMed, Cochrane Library, Embase, EBSCOhost, Web of Knowledge, and Google Scholar reporting on appliance design, bonding, and laboratory setup, biomechanics, survey studies, case reports, and treatment outcomes to find the current evidence of lingual orthodontics. The evidence available on lingual orthodontics traces a very clear and predictable pattern. The 80′s was devoted to the limitation and progression of the concept; the 90′s to the comparison between labial and lingual and the evolution of laboratory technique and bracket system. The last decade focuses on innovations, the predictability of outcomes, the impact of white spot lesion, and the patient acceptability. This review also shows that biomechanical principles of lingual orthodontics are well understood and established today, any case that can be treated with labial orthodontic appliance, can also be treated effectively with lingual orthodontic appliance as the completely customized lingual appliance can provide predetermined treatment outcome.

Cardiac myxomas (CMs) are a major primary heart tumor which often causes unexpected symptoms or sudden death. Among CMs, biatrial myxomas are even rare. This study was designed to investigate the clinical characteristics and surgical treatment of 5 cases with biatrial myxoma, to summarize the treatment experience and the effect of short-to-mid-term prognosis. Five patients with biatrial myxoma were included in this study. The patients' relative literature, chest X-ray, body-surface electrocardiogram, and ultrasonic cardiogram (UCG) were used to investigate the clinical characteristics. The experience of surgical treatment and perioperative treatment were analyzed. Among the 5 cases, patients had presented discomfort of precordial area and cardiac insufficiency symptoms such as dyspnea and chest discomfort. There were characteristic changes on echocardiography (ECG). All patients accepted resection of both tumor and its basement tissue. Their symptoms were all improved after surgery, no deaths occurred. In conjunction with clinical features, diagnostic clue and echocardiography, the detectable rate of biatrial myxoma could be significantly improved. Early diagnosis showed good effect on prognosis.

Eighteen cases of septic osteitis of the distal phalanx were diagnosed clinically and confirmed at surgery over a 6 year period (1990-1996). Focal bone lysis was the most common radiographic finding. Sequestra were identified in 4 horses, one of which was associated with a fractured plantar process. All the horses were treated surgically with open debridement. The septic process recurred in 4 horses: one was subjected to euthanasia due to navicular bursa infection, secondary to a pathological fracture, the other 3 horses responded to further debridement. A pathological fracture occurred in another horse. All the survivors were not lame 3 months post operatively, although complete healing took 1-12 months. Long term follow up was available in 14 cases. One was retired, all the other horses were back in work at a similar level of performance. This series indicates that surgical treatment of septic pedal osteitis carries a fair to good prognosis despite a high rate of post operative complications and convalescence period of up to 12 months

We report a case of repeated surgical resections for the tumor seeding of hepatocellular carcinoma(HCC)after radiofrequency ablation(RFA). A 79-year-old man, who had an intrahepatic recurrence of HCC(segment 2)5 months after RFA, was referred to our hospital for surgery, and underwent a laparoscopic lateral segmentectomy. Histological examination showed a poorly differentiated HCC(pStage II). Eight months after RFA, subcutaneous nodules along the RFA needle tract were pointed out by abdominal CT, and a tumorectomy was performed. Nineteen months after RFA, abdominal CT showed a 33mm tumor on the side of the spleen, leading to the diagnosis of the peritoneal dissemination following RFA. The tumor has been growing up to 49mm in size in spite of a radiation therapy. Accordingly, a laparoscopic tumorectomy was performed 26 months after RFA. His resected tumors were morphologically identical to the intrahepatic recurrence of HCC. The patient had remained recurrence-free for 4 months after the second tumorectomy. Our case demonstrated the utility of surgical resection for the tumor seeding of HCC following RFA.

Superior Canal Dehiscence Syndrome (SCDS) causes auditory and vestibular symptoms. Following surgical repair of the dehiscence, patients often experience dizziness and imbalance. This case report describes a postoperative vestibular exercise program, focusing on the principles of central compensation and habituation, and how it was modified for a patient with delayed progress secondary to strabismus and visual vertigo. A 63-year-old male with history of strabismus eye surgery, right hearing loss, aural fullness, and sensitivity to loud sounds was referred for vestibular rehabilitation (VR). He was seen for one preoperative and six postoperative PT visits over eight months. Outcome measures two weeks postoperative were as follows: Dizziness Handicap Inventory (DHI) 38/100; Timed Up & Go (TUG) 9.92 seconds; Dynamic Gait Index (DGI) 16/24; and a 3-line difference in Dynamic Visual Acuity (DVA). Improved outcomes at discharge included: DHI 18/100; TUG 6.87 seconds; DGI 23/24; and 1-line difference in DVA. He was able to return to work and previously enjoyed recreational activities. Postoperative vestibular rehabilitation programs are functionally and symptomatically beneficial following surgical repair for SCDS. Deviations from expected recovery should be addressed to achieve optimal outcomes as demonstrated in this complicated case report.

Bacterial meningitis (BM) has been recognized as a rare complication of spinal surgery. However, there are few reports on the management of postoperative BM in patients who have undergone spinal surgery. The initial approach to the treatment of patients suspected with acute BM depends on the stage at which the syndrome is recognized, the speed of the diagnostic evaluation, and the need for antimicrobial and adjunctive therapy. Here, we report the case of a patient with lumbar spinal stenosis and underwent a transforaminal lumbar interbody fusion at L4-L5. The dura mater was damaged intraoperatively. After the surgery, the patient displayed dizziness and vomiting. A CSF culture revealed Pseudomonas aeruginosa infection. The patient was diagnosed with postoperative BM. Antibiotic was administered intravenously depends on the organism isolated. Nevertheless, the patient's clinical condition continued to deteriorate. The patient underwent 2 open revision surgeries for dural lacerations and cyst debridement repair. The patient's mental status returned to normal and her headaches diminished. The patient did not have fever and the infection healed. Surgical intervention is an effective method to treat BM after spinal operation in cases where conservative treatments have failed. Further, early surgical repair of dural lacerations and cyst debridement can be a treatment option for selected BM patients with complications including pseudomeningocele, wound infection, or cerebrospinal fluid leakage.

In the case of pneumorrhachis, air can be present in the extradural, the intradural, or the subarachnoid space of the spinal canal. The air within the soft tissue of the posterior mediastinum may dissect along fascial planes, through the intervertebral neural foramina, and into the extradural or the subarachnoid space. Nontraumatic pneumorrhachis is a rare presentation. Most of the time, pneumorrhachis is asymptomatic, remains localized, and resolves spontaneously. There are very few reports of combined presence of pneumomediastinum and extradural pneumorrhachis not associated with thoracic injury in the published literature. We report a rare case of pneumorrhachis, pneumomediastinum, pneumothorax, and surgical emphysema in an adult female patient developed after a bout of violent cough related to bronchial asthma.

We have recently diagnosed several cases of mild trigonocephaly associated with microcephaly. The surgical approach is often difficult to decide for such cases. Surgical treatment is often attempted if neuroradiological studies show evidence of increased intracranial pressure. Twelve patients (9 girls and 3 boys) were found to microcephaly during infancy. All patients had symptoms, including varying degrees of mental retardation, delayed language, hyperactivity, motor dysfunctions, and self-mutilation (head banging). Most patients had mild trigonocephaly with microcephaly and tended to be of short stature. Head circumferences were at least 2 standard deviations below the mean for age at the time of surgery. Mild trigonocephaly was diagnosed in all patients by means of 3-dimensional computed tomography. Magnetic resonance of the brain showed no abnormalities in any patient. Plain skull X-ray films showed marked digital markings in 8 patients. Intracranial pressure was measured under normocapnia: results were obtained in 9 patients, and intracranial pressure was increased in 8 patients. Decompressive cranioplasty was performed in all patients. After surgery, chronological measurements showed tendencies for head circumferences to increase in 7 patients. Cognitive impairment showed no change, but other symptoms showed some improvement in all patients. These results suggest that surgery is indicated for patients with mild trigonocephaly associated with microcephaly if intracranial pressure is increased and if magnetic resonance of the brain shows no abnormalities.

Full Text Available The purpose of the present case report was to describe the surgical treatment of a peri-implantitis lesion associated with a regenerative approach. A 48-year-old patient came to authors’ attention 36 months after the placement of a dental implant (ITI-Bonefit Straumann, Waldenburg, Switzerland in position 46. A swelling of the peri-implant soft tissues was observed, associated with bleeding on probing and probing depth > 10 mm. A significant peri-implant bone loss was clearly visible on the periapical radiograph. A nonsurgical periodontal supportive therapy was firstly conducted to reduce the inflammation, followed by the surgical treatment of the defect. After mechanical and chemical decontamination with tetracycline solution, a regenerative approach consisting in the application of deproteinized bovine bone mineral (Bio-Oss, Geistlich Pharma AG, Wolhusen, Switzerland and a collagen membrane (Bio-Gide, Geistlich Pharma AG, Wolhusen, Switzerland was performed. An antibiotic therapy was associated with the treatment. The 17-year follow-up showed a physiological probing depth with no clinical signs of peri-implant inflammation and bleeding on probing. No further radiographic bone loss was observed. The treatment described in the present case report seemed to show improved clinical results up to a relevant follow-up period.
Full Text Available AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation. METHODS: Retrospective study. Clinical data of 105 cases(105 eyesdiagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy.Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases.Preoperative and postoperative LogMar(Logarithm of the Minimum Angle of Resolutionvisual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed. RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes(86.7%were significantly improved postoperatively.The visual acuity of most patients was 0.1-0.3(42 eyes, 40.0%and 1 patient's visual acuity with lens subluxation reached more than 0.8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively. CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation.Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.
Full Text Available Pneumatosis intestinalis (PI is an uncommon condition and can be associated with a wide spectrum of diseases, ranging from life-threatening to innocuous conditions. We report the case of a 46-year-old women coming to our attention for an acute abdominal pain, nausea, vomiting, constipation, and increased inflammatory marks, with a CT showing pneumoperitoneum and pneumatosis intestinalis. The previous diagnosis was advanced neoplasia of unknown origin. Despite the surgical intervention, which excluded an ischemic colitis, the patient died in the early postoperative period. The postmortem diagnosis was carcinoma of thymus gland, and the presence of pneumatosis was put down to metastasis nodes in the pulmonary parenchima. This case demonstrates the wide spectrum of presentation of pneumatosis intestinalis, the importance of a careful radiologic evaluation beside the clinical history, since the identification of correct pathogenesis and treatment can be very difficult.

There is no current consensus on the best treatment modality for cesarean scar pregnancy (CSP) with favorable reproductive and pregnancy outcome. We treated 3 cases of symptomatic CSP with fetal cardiac activity. The first case underwent laparoscopic repair at 6 weeks' gestational age of unruptured CSP. The second patient underwent laparoscopic repair due to massive vaginal bleeding after suction curettage. Both patients conceived naturally 6 months later and underwent repeated cesarean section at term. These were successful live births although the second patient was treated with uterine artery embolization for postpartum hemorrhage. The last patient underwent emergency exploratory laparotomy due to ruptured CSP and delivered a preterm baby. Earlier surgical treatment of CSP is indicated for a subsequent successful pregnancy and live birth. The laparoscopic approach might be advisable prior to uterine rupture. © 2014 S. Karger AG, Basel.

Placebo is a form of simulated medical treatment intended to deceive the patient/subject who believes that he/she received an active therapy. In clinical medicine, the use of placebo is allowed in particular circumstances to assure a patient that he is taken care of and that he/she receives an active drug, even if this is not the case. In clinical research placebo is widely used, as it allows a baseline comparison for the active intervention. If the use of placebo is highly regulated in pharmacological trials, surgery studies have a series of particularities that make its use extremely problematic and regarded less favorably. The purpose of this paper is to present three famous cases of placebo use in surgical trials and to perform an ethical analysis of their acceptability using the Declaration of Helsinki as a main regulatory source.

Full Text Available Head injuries following fall of heavy objects are not very uncommon in developing countries. However, compound depressed skull fracture with superior sagittal sinus (SSS laceration caused by a flying asbestos fragment in a stormy afternoon is an unusual mode of head injury. We report such an unusual case of compound depressed skull fracture by an asbestos fragment injuring the middle third of SSS and its successful surgical management in a 14-year-old child. The role of computed tomography (CT scan of head with 3D reconstruction is highlighted. Early steps taken in this case to check the profuse bleeding, which helped save the life of this boy is interesting to note.

Although rarely discussed in the literature and difficult to evaluate on plain radiographs, atlantooccipital osteoarthritis can be a source of persistent suboccipital pain. Our objective in this report is to describe two cases with atlantooccipital (O-C1) osteoarthritis treated with posterior occipitocervical fusion. Two patients presented with unilateral suboccipital pain, which was refractory to conservative treatment. One patient suffered from long-standing rheumatoid arthritis while the other patient did not have pertinent medical issues. After non-diagnostic plain film imaging, CT scan demonstrated unilateral osteoarthritis of the atlantooccipital and atlantoaxial joint in both patients who subsequently underwent posterior O-C2 fusion with resolution of their preoperative symptoms. This is, to our knowledge, the first case report which specifically focused on surgical treatment of atlantooccipital osteoarthritis. Occipitocervical fusion is a treatment option for patients with atlantooccipital osteoarthritis when suboccipital pain is not responsive to conservative treatment.

A 9-year-old girl with Papillon-Lefèvre syndrome (PLS) was treated orthodontically 24 months after the start of mechanical and antibiotic therapy in adjunct with periodontal treatment every 6 weeks. After achieving stable periodontal conditions, orthodontic treatment was commenced to correct the teeth position, facial profile, and maxillary protraction. Following the combination therapy and a failure to detect Actinobacillus actinomycetemcomitans from any site in the oral cavity, orthodontic treatment with a fixed appliance was performed aside from creating space for eruption of permanent teeth. We found that combined periodontal and orthodontic treatment of PLS may be successful with a complex interdisciplinary regimen and close follow up. This is a 2-year follow-up case report of a girl with PLS. Orthodontic and periodontic therapy were offered using combined treatments of orthodontic and periodontal with the benefit of prosthodontic consultation, resulting in a treatment plan.

Esophageal perforation has been considered a catastrophic and often life-threatening event, with very high mortality rates. Most of the cases are due to a complication in endoscopic manouvers and the best treatment, conservative rather than aggressive, remains a controversial topic. In 1995-2005 period we observed 7 cases of esophageal perforation, 5 women and 2 men mean age 73.2 y (range 60-87). Three cases are due to foreign body ingestion, 2 cases to endoscopic manoeuvres, 2 cases were spontaneous. In 3 cases the lesion was in the cervical tract of the esophagus, in the thoracic tract the others. All the patients were admitted very early to our Unit and presented disphagia, vomiting and dyspnoea, 2 out of them also a pleural effusion. In iatrogenic perforation we performed a cervicotomy and a drainage of mediastinic abscess, while in spontaneous lesions mono (one case) or bipolar esophageal exclusion (one case) with primary suture, jujunostomy and drainage of pleural effusion were the treatment. In foreign body perforation we performed thoracotomic and cervicotomic esophagotomy, extraction of the foreign body, direct suture with pleural or muscle protection. We didn't observe any intra or post-operative mortality. About the complications, we observed a bilateral pleural empyema, a chylous fistula, a digestive bleeding due to gastric ulcer, a laparotomic infection, a parossistic FA and a persistent esophageal fistula. Mean hospital stay was 24.3 days (range 10-43). All the patients were discharged to the hospital in good conditions. In conclusion in most of the cases of esophageal perforation the surgical treatment is the treatment of choice for its lower morbidity and mortality and good functional results.

Venous thromboembolism, risk of which is increased in surgical patients, is a preventable cause of morbidity and death. The primary objective of this study was to estimate the incidence of symptomatic postoperative venous thromboembolism in adults at a tertiary university hospital, overall and by surgical specialty. The secondary objective was to analyze severity of and mortality from thromboembolic events. We performed a retrospective study to identify cases of in-hospital postoperative venous thromboembolism, encoded by the International Classification of Diseases, Ninth Revision, according to the Joint Commission International criteria. Adult patients admitted for surgery in 2008-2012 were included. Among 67 635 hospitalizations, 90 cases of postoperative symptomatic venous thromboembolism were identified, corresponding to an incidence of 1.33/1000 admissions (95% confidence interval [CI] 1.1-1.6/1000). Neurosurgery had the highest risk (4.07/1000), followed by urological surgery and general surgery (p<0.001). There were 50 cases of pulmonary embolism, 11 of which were fatal. Of the 90 cases, 12.2% occurred under neuraxial anesthesia and 55.1% in patients with American Society of Anesthesiology III physical status. At least 37.7% of patients with events received a prophylactic dose of injectable anticoagulant postoperatively. The overall risk decreased from 2008 to 2012. Venous thromboembolism-associated mortality during hospitalization was 21.1% (95% CI 13.6-30.4). The incidence of postoperative symptomatic venous thromboembolism was 1.33/1000. Neurosurgery showed the greatest risk. Mortality was 21.1%. Copyright © 2017 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U. All rights reserved.

The aim of this case study was to provide a detailed report of the orthodontic approach used in treating a Japanese patient with congenital hypoglossia. The patient was a 6-year-old girl with hypoglossia, micrognathia, congenital absence of three incisors, and a telescopic occlusion accompanied by an extremely narrow lower arch. She had no limb anomalies, and her speech was normal. Bite opening and mandibular widening from the early mixed dentition dramatically improved the extremely constricted mandible and telescopic occlusion. Cephalometric tracings taken from the beginning to the end of active treatment revealed substantial forward and downward growth in the mandible over time, which may have contributed to correction of the intermaxillary relationship. Treatment of telescopic occlusion by bite opening and mandibular widening from the early mixed dentition may be effective in facilitating mandibular growth acceleration. An acceptable intermaxillary occlusal relationship and improvement of profile were achieved by an orthodontic approach in this case.

Lingual orthodontics is a relatively new method of delivering orthodontic treatment. These appliances may be used on any patient, but they have a special application for that small group of adult patients who need orthodontic treatment but refuse to accept the appearance of conventional appliances. The technique is difficult to manage and should be used only by experienced orthodontists. Although the patients may experience difficulties, these are usually adequately compensated for by the improved aesthetics.

We report a 16-year-old pubescent pediatric patient with obstructive sleep apnea syndrome (OSAS) and short stature whose apnea hypopnea index (AHI) was significantly reduced following the use of an orthodontic oral appliance that advances the mandible ventrally. The mandible was advanced 64% of the maximal mandibular protrusive position with use of the appliance over a 3-year period. The patient's AHI without the appliance in place decreased from 101.6/h at baseline to 11/h after treatment. Moreover, the patient's height increased 14 cm during treatment, resulting in height close to the average height for his age. Cephalometric analysis revealed an improvement in his retrognathic mandible and proclination of the upper front teeth. In conclusion, an orthodontic mandibular advancement oral appliance played an important role not only in improving the patient's OSAS but also in normalizing his physical growth during puberty. © 2015 American Academy of Sleep Medicine.
Full Text Available Aggressive periodontitis is characterized by non-contributory medical history, rapid attachment loss and bone destruction and familial aggregation of cases. Aggressive periodontitis (both localized and generalized is usually diagnosed in a young population. This is frequently the age that an orthodontic care is provided to this population. The aim of the present paper is to draw guidelines for periodontal evaluation and monitoring prior to and during active orthodontic treatment. Strict adherence to these guidelines as a routine protocol for periodontal examination prior, during and following orthodontic treatment may dramatically decrease the severity and improve the prognosis of patients with aggressive periodontitis in orthodontic clinics.
Full Text Available Surgical removal of the mandibular third molar is a regular surgical procedure in dental clinics, and like all operations, it may have some complications, such as infection, bleeding, nerve injuries, trismus and so on. An accidentally displaced lower third molar is a relatively rare complication, but may cause severe tissue injury and medicolegal problems. As few papers and cases have been published on this topic, we report this case to remind dentists on ways to prevent and manage this complication. The patient, a 28-year-old male, had his right lower mandibular third molar extraction in January 2006. The dentist resected the crown and attempted to remove the root but found that it had suddenly disappeared from the socket. Assuming that the root had been suctioned out he closed the wound. The patient was not followed up regularly because he studied abroad. About 3 months later, the patient felt a foreign body sensation over his right throat, and visited a local hospital in Australia. He was told after a computed tomography (CT scan that there was a root-like radio-opaque image in the pterygomandibular space. The patient came to our hospital for further examination and management in June 2006. We rechecked with both Panorex and CT and confirmed the location of the displaced root. Surgery for retrieving the displaced root was performed under general anesthesia by conventional method without difficulty, and the wound healed uneventfully except for a temporary numbness of the right tongue. This case reminds us that the best way to prevent a displaced mandibular third molar is to evaluate the condition of the tooth carefully preoperatively, select adequate instruments and technique, and take good care during extraction. If an accident does occur, dentists should decide whether to retrieve it immediately by themselves or refer the case to an oral and maxillofacial surgeon, and should not try to remove the displaced root without proper assurance

Pain is an undesirable side effect of orthodontic tooth movement, which causes many patients to give up orthodontic treatment or avoid it altogether. The aim of this study was to investigate, through an analysis of the scientific literature, the best method for managing orthodontic pain. The methodological aspects involved careful definition of keywords and diligent search in databases of scientific articles published in the English language, without any restriction of publication date. We recovered 1281 articles. After the filtering and classification of these articles, 56 randomized clinical trials were selected. Of these, 19 evaluated the effects of different types of drugs for the control of orthodontic pain, 16 evaluated the effects of low-level laser therapy on orthodontic pain, and 21 evaluated other methods of pain control. Drugs reported as effective in orthodontic pain control included ibuprofen, paracetamol, naproxen sodium, aspirin, etoricoxib, meloxicam, piroxicam, and tenoxicam. Most studies report favorable outcomes in terms of alleviation of orthodontic pain with the use of low-level laser therapy. Nevertheless, we noticed that there is no consensus, both for the drug and for laser therapy, on the doses and clinical protocols most appropriate for orthodontic pain management. Alternative methods for orthodontic pain control can also broaden the clinician's range of options in the search for better patient care.

Situs inversus totalis (SIT) is a rare condition, in which there is transposition of the thoraco-abdominal organs. This situation leads to diagnostic and therapeutic difficulties in patients with acute surgical abdomen. The objective of this report is to present the case of a patient who presented with colonic pain in the epigastrium and left hypochondrium, in which the diagnosis of SIT, cholelithiasis and choledocholithiasis was reached after the respective imaging studies. Once the diagnosis was made, treatment was performed through retrograde endoscopic cholangiopancreatography (ERCP) and subsequent surgical exploration of bile ducts. Both procedures were failed due to technical difficulties generated by the patient's condition. In conclusion, in spite of the report of successful cases in the literature of ERCP and surgical treatment of the biliary tract in SIT, there may be situations that do not allow a successful approach, so meticulous surgical planning and the use of support methods are necessary In the management of these patients.

Full Text Available Masseteric hypertrophy, popularly called the benign masseteric hypertrophy (BMH or idiopathic masseteric hypertrophy (IMH is a relatively uncommon condition characterized by asymptomatic enlargement of one or both masseter muscles and is rarely accompanied by pain, which is often confused with parotid swelling. Most frequently, clinicians are consulted for swelling of angle of mandible which needs to be corrected for cosmetic reasons. Although it is tempting to produce malocclusions, bruxism, clenching, temporomandibular joint disorders, the etiology in majority of the cases are unknown. The purpose of this review is to have a discussion on the effects of masseter muscle on craniofacial morphology, its implication in different types of malocclusion and contemporary orthodontic management and stability.

Full Text Available CONTEXT AND OBJECTIVE: The incidence of scar endometrioma ranges from 0.03 to 3.5%. Certain factors relating to knowledge of the clinical history of the disease make correct diagnosis and treatment difficult. The aim here was to identify the clinical pattern of the disease and show surgical results. The literature on this topic was reviewed. DESIGN AND SETTING: Retrospective descriptive study at Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. METHODS: Data from the medical records of patients with preoperative diagnoses of scar endometrioma who underwent operations between 2001 and 2007 were surveyed and reviewed. The postoperative diagnosis came from histopathological analysis. The main information surveyed was age, obstetric antecedents, symptoms, tumor location, size and palpation, duration of complaint, diagnosis and treatment. All patients underwent tumor excision with a safety margin. RESULTS: There were 33 patients, of mean age 30.1 ± 5.0 years (range: 18-41 years. The total incidence was 0.11%: 0.29% in cesarean sections and 0.01% in vaginal deliveries. Twenty-nine tumors (87.9% were located in cesarean scars, two (6.0% in episiotomy scars and two (6.0% in the umbilical region. The main symptom was localized cyclical pain (66.7%, of mean duration 30.5 months (± 23. Surgical treatment was successful in all cases. CONCLUSION: This is an uncommon disease. The most important diagnostic characteristic is coincidence of painful symptoms with menstruation. Patients undergoing cesarean section are at greatest risk: relative risk of 27.37 (P < 0.01. The surgical treatment of choice is excision of the endometrioma with a safety margin.

To describe a technique for tracheostomy in heterotopic ossification that has not yet been described in the literature. We report a case of difficult tracheostomy while using conventional techniques in a 68-year-old patient who underwent mitral valve replacement requiring warfarin therapy three months prior. Imaging revealed heterotopic ossification overlying the trachea. A literature review was performed to identify similar cases or techniques. Extensive surgical planning was pursued after the initial attempted tracheostomy failed, and the airway was eventually accessed using a lighted intubation stylet for guidance and a drill. Heterotopic ossification has been described after orthopedic and abdominal surgeries. We identified one case report in the literature of tracheostomy performed in the setting of heterotopic ossification by an unspecified mechanism. There are few reported cases of tracheobronchial calcification in cardiac patients receiving warfarin therapy; however, these patients had characteristic imaging findings that were not consistent with those of our patient. We illustrate a safe and effective technique for tracheostomy in heterotopic ossification that has not been reported. Coordination with the anesthesia service was paramount for a successful operation. © The Author(s) 2016.

The authors report one operated case of traumatic sternal segmental dislocation in a child, and propose a mechanism for this uncommon lesion. A fourteen year old boy was admitted in emergency for anterior chest pain, occurring during an exercise in parallel bars without any fall. X ray showed traumatic dislocation of the upper sternal segment. After 12 hours, because of bad clinical tolerance (pain, dyspnea with sweats and disphagia) reduction and plate stabilization (Senegas plate) was performed with immediate pain relief. The boy returned to school after 10 days. Plate was removed two months later after healing, with good clinical and radiological results. According to rare published cases, conservative treatment can be proposed in very young children because of dislocation remodeling. By others, in case of bad tolerance, surgical treatment is suggested despite the inconvenient of device's removal. The originality of this case is the indirect lesion mechanism. Hypothesis is given by authors. Treatment by plate is easy and gives immediate pain relief with good clinical and radiological results in teen-agers.

Improper tooth alignment due to crowding, malocclusion, and missing teeth can cause difficulties with eating and speech, and premature wear. It is estimated that more than 20% of children would benefit from orthodontic treatment to correct these conditions, many of which will persist into adulthood if not corrected. Orthodontic care is gaining popularity among adults for similar concerns, as well as for correction of cosmetic issues. The psychological effects of malocclusion should not be ignored. The American Association of Orthodontists recommends that all children undergo evaluation at the first recognition of an orthodontic condition and no later than age 7 years. Some children will need early treatment to help eliminate developing conditions and improve the foundations of the bite, which can ease later treatment in adolescence. For others, treatment in adolescence without early treatment is recommended. Standard cemented braces or clear, removable aligners may be used, depending on the patient's corrective needs. Average treatment time is approximately 2 years; this may be shortened by the use of accelerative techniques. Routine preventive dental care should be continued during the treatment period.

To evaluate diagnostic methods, surgical treatment, perioperative management, and renal function of cats with obstructive calcium oxalate ureteroliths. Retrospective case series. 11 cats that underwent surgery for removal of calcium oxalate ureteroliths. Medical records were reviewed, and the following information was recorded: signalment; results of physical examination, clinicopathologic analyses, and abdominal imaging; surgical procedure; postoperative management; and results of ureterolith quantitative analysis. Ureteroliths in the proximal portion of the ureter were removed from 5 cats (pyelotomy, 1 cat; unilateral ureterotomy, 2 cats; bilateral ureterotomies, 2 cats). Calculi in the middle and distal part of the ureter were removed by partial ureterectomy and ureteroneocystostomy (6 cats). Ten cats recovered from surgery and were discharged from the hospital. One cat died from unknown causes 4 months after surgery, and 1 cat had a nephrectomy elsewhere 5 weeks after ureterolith removal. Eight cats were evaluated 12 to 20 months after surgery. Of these, 2 cats that were markedly azotemic before surgery improved after surgery, and 2 cats developed nephroliths after surgery. Also, of 5 cats that had nephroliths that were not removed at the time of surgery, 4 still had visible nephroliths. One cat had recurrent ureteral obstruction from a ureterolith and persistent urinary tract infection. Ureteroliths or ultrasonographic evidence of ureteral obstruction were not detected in other cats. A combination of microsurgical techniques and intensive postoperative care is necessary to minimize morbidity of cats after removal of a ureterolith. Renal function may improve or stabilize after removal of the ureteral obstruction

Full Text Available Secondary hyperparathyroidism (sHPT occurs most commonly in the setting of chronic renal failure (CRF being frequently referred to as “renal” hyperparathyroidism The “classical” medical treatment with oral calcium and vitamin D supplementation is generally sufficient to lower parathyroid hormone levels in the majority of these patients. However, we frequently encounter cases of severe refractory sHPT, a state in which even recently available therapeutic agents, i.e. calcimimetics, new phosphate binders, vitamin D analogues, remain inefficient, thus parathyroidectomy and/or renal transplant becoming necessary. Three types of surgeries have been proposed in sHPT: two of them are grouped as remnant-conserving techniques, i.e. subtotal parathyroidectomy (sPtx and total parathyroidectomy with autotransplantation (tPtx+AT, the third one being total parathyroidectomy without autotransplantation (tPtx. There was a continuous debate concerning the best surgical approach in renal hyperparathyroidism, starting very soon after those techniques were described; without pretending to solve these controversies, this paper aims to review the surgical treatment options in sHPT, based on our 5-year experience in dealing with the disease.

Full Text Available Congenital radioulnar synostosis is an uncommon condition, only 400 cases have been reported in the world literature. Often bilateral, it can be recognized from birth by a clinical examination if it is attentive (examination of the prono-supination of the two elbows. It is in fact often discovered later, especially in unilateral forms, in children of school age. The proximal congenital radioulnar synostosis often results in functional, cosmetic limitations of the upper limb especially in the bilateral forms. Rotational osteotomy through the synostosis site is the usual procedure. The techniques and sites envisaged for this surgery are numerous, with multiple difficulties, risks and possible complications. We propose the observation of an eight-year-old boy with a symptomatic form of proximal radioulnar synostosis. The surgical treatment consisted of a resection of the synostosis with rotational transversalosteotomy of the two bones of the forearm completed by a plaster in neutral position. Clinical results, evaluated at an average of twelve months postoperatively, were found to be satisfactorily on aesthetic and functional levels. The aim of our work is to highlight our simple and reliable surgical procedure of the osteotomy of the synostosis maintained by spindles, allowing the functional improvement of the movements of the forearm of our child and thus a normal life.

Posterior non-ischemic left ventricular aneurysms are unusual aneurysms of different etiology that develop adjacent to the mitral valve annulus causing mitral regurgitation and progressive heart failure. Surgical correction is mandatory and involves repair of the aneurysm along with repair or replacement of the mitral valve. Two cases of posterior non-ischemic left ventricular aneurysms are reported. Both patients were females (19 and 9 years old) and they presented with symptoms of progressive heart failure. Definite diagnosis was made with transesophageal echocardiography (TEE) and confirmed with left ventriculography. Both patients were successfully treated by surgery. The first patient underwent repair of the aneurysm from inside the left ventricle and mitral valve replacement. The second patient had resection of the aneurysm through an extracardiac route. Both patients are in NYHA class 1, 5 and 4 years respectively after their operation with no evidence of mitral valve dysfunction. Posterior non-ischemic left ventricular aneurysms can securely be diagnosed by TEE and angiocardiography. Surgical treatment is mandatory in order to forestall potential life threatening cardiovascular events and should be tailored to the operative findings.
Full Text Available Introduction. Median arcuate ligament (MAL syndrome, also called celiac trunk compression syndrome (CACS or Dunbar syndrome is a rare disorder caused by compression of the celiac artery by median arcuate ligament of the diaphragm, which leads to mesenteric ischemia and chronic abdominal angina. The typical clinical triad of symptoms includes postprandial epigastric pain, weight loss and vomiting. The gold standard for MAL syndrome diagnosis is selective angiography, while in symptomatic patients with angiographically verified stenosis the optimal therapy is surgical treatment. Case Outline. A 40-year-old male patient was presented with epigastric pain, followed by dyspepsia and weight loss. The upper endoscopy showed gastric and duodenal distention with prominent folds of gastric mucosa and slow peristalsis. Selective angiography showed stenosis (90% of initial segment of the celiac trunk. Adhesiolysis with the transection of the median arcuate ligament was performed. Due to repeated symptoms, the patient was reoperated on the 10th postoperative day with performed adhesiolysis and gastrostomy for gastric nutrition. Two months later, the patient was rehospitalized for closure of gastrostomy. At five years follow-up, selective angiography showed no stenosis of the initial segment of the celiac artery. Conclusion. Despite the existing controversy concerning pathophysiological mechanism, the clinical presentation and treatment modalities of patients with MAL syndrome, it is evident that careful selection and adequate surgical treatment may significantly reduce symptoms in these patients.

The aim of this study was to investigate, through an analysis of the scientific literature, the best method for managing orthodontic pain. The methodological aspects involved careful definition of keywords and diligent search in databases of scientific articles published in the English language, without any restriction of publication date. We recovered 1281 articles. After the filtering and classification of these articles, 56 randomized clinical trials were selected. Of these, 19 evaluated the effects of different types of drugs for the control of orthodontic pain, 16 evaluated the effects of low-level laser therapy on orthodontic pain, and 21 evaluated other methods of pain control. Drugs reported as effective in orthodontic pain control included ibuprofen, paracetamol, naproxen sodium, aspirin, etoricoxib, meloxicam, piroxicam, and tenoxicam. Most studies report favorable outcomes in terms of alleviation of orthodontic pain with the use of low-level laser therapy. Nevertheless, we noticed that there is no consensus, both for the drug and for laser therapy, on the doses and clinical protocols most appropriate for orthodontic pain management. Alternative methods for orthodontic pain control can also broaden the clinician’s range of options in the search for better patient care.

Full Text Available OBJECTIVES: To investigate the clinical manifestation and surgical outcome of spinal osteoblastoma. METHODS: From June 2006 to July 2011, 18 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 11 males and 7 females with an average age of 27.5 years（range, 16-38 years. The tumors were located at C5 in 7, C6 in 6, C7 in 3, C6-T1 1 in 1 and T11 in 1. Based on WBB classification, 16 were 1-3 or 10-12 and 2 were 4-9 and 1-3. 18 operations had been performed with en bloc resection. A posterior approach was used for 16 patients, and a combined posterior and anterior approach was used for 2 patients. Reconstruction using instrumentation and fusion was performed using spinal instrumentation in 13 patients. We used visual analogue scales (VAS to evaluate the change of pain before and after the operation, and the McCormick System to assess functional status of the spine. Imaging test was used to review the stability and recurrence rate of spine cord, and the confluence of graft bones. RESULTS: All cases were followed up for 24-80 months (average, 38.4 months. The average surgical time was 120.8 minutes (range, 80-220 minutes, with the average intraoperative blood loss of 520 ml (range, 300-1200 ml. During the follow-up period, the VAS grade reduced from 6.46±1.32 to 2.26±1.05 (P <0.05. 15 patients had neurological function improved and 3 remained no change which was evaluated by McCormick scale for spinal function status at final follow-up. CONCLUSIONS: Spinal osteoblastoma has its own specific radiographic features. There is some recurrence in simple curettage of tumor lesion. The thoroughly en bloc resection of tumor or spondylectomy, bone fusion and strong in Ter fixation are the key points for successful surgical treatment.

Full Text Available This paper reports a series of clinical cases of ankyloglossia in children, which were approached by different techniques: frenotomy and frenectomy with the use of one hemostat, two hemostats, a groove director or laser. Information on the indications, contraindications, advantages and disadvantages of the techniques was also presented. Children diagnosed with ankyloglossia were subjected to different surgical procedures. The choice of the techniques was based on the age of the patient, length of the frenulum and availability of the instruments and equipment. All the techniques presented are successful for the treatment of ankyloglossia and require a skilled professional. Laser may be considered a simple and safe alternative for children while reducing the amount of local anesthetics needed, the bleeding and the chances of infection, swelling and discomfort.

Presented herein is a clinical case report regarding hybrid or two-stage surgical treatment of a Crawford type II thoracoabdominal aortic aneurysm in an 87-year-old woman. For the first stage operation we performed open resection of the abdominal aortic aneurysm with aortofemoral bifurcation prosthetic repair and debranching of visceral and renal arteries. Several months thereafter, the second stage operation was performed, consisting in transcatheter exclusion of the thoracoabdominal aortic aneurysm with the help of two stent grafts. The postoperative period turned out uneventful, with no complications. The check-up contrast-enhanced multislice computed tomography (MSCT) carried out 8 months later showed neither endoleaks nor migration of the stent grafts, with the bypass shunts' patency preserved.
Discussion: Paragangliomas are solid, slow growing tumors arising from specialized neural crest cells, mostly occurring in the head and neck and rarely in cauda equina or filum terminale. MRI is gold standard radiological for diagnosis and follow-up of these lesions. They have no pathognomonic radiological and clinical features and are frequently misdiagnosed as other spinal lesions. No significant correlation was observed between the duration of symptoms and tumor dimension. Acute presentation is unusual and emergent surgical treatment is fondamental. The outcome is very good after complete excision and radiotherapical treatment is recommended after an incomplete resection. Conclusion: Early radiological assessment and timely surgery are mandatory to avoid progressive neurological deficits in case of acute clinical manifestation of paraganglioma of filum terminale.

We present the case of a 58-year old male patient admitted in the surgery section of the University Emergency Hospital of Bucharest and diagnosed with acute abdomen. The minimal clinical-paraclinical investigation (i.e., thorax-pulmonary Xray, biological probes) raises questions as to the differentiated diagnosis and other associated diseases, also suggesting the existence of voluminous diaphragmatic hernia. The CT thorax-abdomen examination confirms the diaphragmatic hernia suspicion, with intra-thorax ascent of the colon up to the anterior C4 level, but does not explain the abdominal suffering; thus we suspected a biliary ileus or acute appendicitis. Medial laparotomy was imperative. Intrasurgically peritonitis was noticed located by gangrenous acute apendicitis, perforated, with coprolite, for which apendictomy and lavage-drainage pf the peritoneal cavity was performed. Post-surgical status: favourable to recovery.

Full Text Available Over a seven-year period, chronic otitis externa was surgically managed in 43 dogs at the University Veterinary Hospital of University College Dublin. Lateral ear canal resection (LECR was undertaken in nine of the 43 dogs: results were unsatisfactory, with a failure of the surgery in five of eight dogs and one dog lost to follow-up. Once end-stage otitis externa, with or without otitis media, is diagnosed, total ear canal ablation and lateral bulla osteotomy (TECA/LBO is the best treatment option. In this series, 37 of 43 dogs underwent TECA/LBO and of the 29 dogs for which follow-up results were obtained 27 (93% had an excellent or improved outcome to surgery. Complications following all procedures were most common in cases with a concurrent dermatopathy; therefore, definitive diagnosis and medical treatment for skin and ear disease is essential.

Non-union occurs when bone healing ceases and does not continue without some type of intervention. Classification of non-union is traditionally based on the amount of callus or bone healing at the fracture site. Successful treatment of non-union often depends on appropriate reduction and realignment of the fracture, bone grafting if necessary, and stabilization. This may not be possible in some neglected and complicated non-unions. Under these circumstances, modification of the standard techniques or a limited surgical interference, that might not be anatomical, may succeed in improving function. We present four cases of non-anatomical salvage solutions for difficult long bone non-unions with satisfactory functional outcome.

Full Text Available Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Although these tumors have different histologic aspects, they may cause similar abdominal and cardiac symptoms and are a serious risk factor for pulmonary embolism and sudden death when they reach the right atrium and tricuspid valve. The best treatment is radical surgical resection of the entire tumor using cardiopulmonary bypass with or without deep hypothermia and total circulatory arrest. We report the cases of two patients, the first with leiomyosarcoma of the inferior vena cava and the other with intravenous leiomyomatosis of the uterus that showed intravascular growth up to right atrium and ventricle, who underwent successful radical resection in a one-stage procedure with the use of cardiopulmonary bypass. We discuss the clinical and histologic aspects and imaging diagnosis and review the literature.
Full Text Available A 67-year-old man was admitted with severe back pain and bilateral lower limb swelling. Enhanced computed tomography showed an infrarenal abdominal aortic aneurysm (92 × 75 mm 2 and a short aortocaval fistula (7 mm. Immediately afterward, circulatory collapse occurred, and the patient was rushed to the operating theater. A much larger aortocaval fistula (22 × 35 mm 2 than that demonstrated by preoperative computed tomography was found and was repaired with a Dacron patch while using two balloon-tipped catheters to control bleeding. Then, the abdominal aortic aneurysm was replaced with a bifurcated graft. The patient’s postoperative course was uneventful. In this case, enhanced computed tomography detected the aortocaval fistula, but could not assess its size accurately. Successful surgical repair of an aortocaval fistula depends on early accurate delineation of the fistula and prompt control of bleeding.
Patient demand for invisible esthetic orthodontic appliances is steadily increasing. Two types of orthodontic appliances have a high rate of patient acceptance. The lingual technique has continually evolved by offering both prefabricated brackets or custom-made brackets. The various techniques have been improved over time, and the results are better than ever. Thermoplastic aligners are an alternative to lingual devices and their use is rapidly growing. Their specific properties make it easier to assess their indications and limitations. A review of the literature, the development of these systems and a presentation of some clinical examples of treated cases will help us to provide some of the basics for understanding each of these two types of appliances and to demonstrate the advantages and disadvantages of each system. © EDP Sciences, SFODF, 2014.

Full Text Available Marfan syndrome is a heritable disorder of connective tissue that can affect the heart, blood vessels, lungs, eyes, bones and ligaments. It is characterized by tall stature, elongated extremities, scoliosis and a protruded or caved-in breastbone. Patients typically have a long, narrow face. A high-arched palate produced by a narrow maxilla and skeletal Class II malocclusion due to mandibular retrognathia are other common features. For a patient with no family history of this disorder, at least three body systems must be affected before a diagnosis can be made-skeletal, cardiovascular and occular. Individuals affected by the syndrome routinely demand orthodontic treatment to correct the orofacial manifestations. This case report presents two patients who reported to the department of orthodontics with a chief complaint of protruding upper anteriors, but on thorough clinical examination and investigation were diagnosed as Marfan syndrome. A brief overview of the challenges involved in treating such patients is discussed herewith.

Paragangliomas of filum terminale are rare benign tumors, arising from the adrenal medulla or extra-adrenal paraganglia. These lesions usually present with chronic back pain and radiculopathy and only two cases of acute neurological deficit have been reported in literature. A case with an acute paraplegia and cauda equina syndrome due to an hemorrhagic paraganglioma of the filum terminale is described. Magnetic resonance imaging showed an intradural tumor extending from L1 to L2 compressing the cauda equina, with an intralesional and intradural bleed. An emergent laminectomy with total removal of the tumor was performed allowing a post-operative partial sensory recovery. Histopathological examination diagnosed paraganglioma. Paragangliomas are solid, slow growing tumors arising from specialized neural crest cells, mostly occurring in the head and neck and rarely in cauda equina or filum terminale. MRI is gold standard radiological for diagnosis and follow-up of these lesions. They have no pathognomonic radiological and clinical features and are frequently misdiagnosed as other spinal lesions. No significant correlation was observed between the duration of symptoms and tumor dimension. Acute presentation is unusual and emergent surgical treatment is fondamental.

Full Text Available Lipoma arise in almost 50% of all soft tumours. The neck lipomas are rare tumours that may present as painless masses with slow growth, in the lateral portions of the neck. Some lipomas, such as the one studied in our case, grow deep in the subcutaneous tissue, in close contact with muscles. Here, we report a case of lipoma extending from pre-tragal region up to the ascending branch of the mandible in a 62 year old man, treated with enucleation. The inferior margin of lipoma involved the pharyngeal and the superior margin was achieved by the top of the skull base. The mass of lipoma caused breathing difficulties in the patient, preventing regular sleep. No complication was recorded in the post-operative period and no further surgery was performed. The complete resolution after one year′s follow-up, together with the rarity of the anatomical site, makes this case worthy of description. A correct diagnosis facilitated removal of this lesion with a surgical method.

Use of traditional orthodontic measures in the periodontally compromised dentition can be problematic. This article describes a variation of the Grassline technique, in which the author uses adhesive bonding to harmoniously re-align malpositioned teeth. In this simple, easy-to-learn technique, a cotton thread is used to achieve orthodontic tooth movement. Initial contact with the saliva causes shrinkage of the thread, exercising a minor force that moves the teeth while allowing enough time for the tissues to regenerate. With this moderate, intermittent force, successful treatment is achieved with minimal risk. Moreover, this orthodontic technique has been associated with an increase in bone volume. This article presents this new technique and details methods for maintaining treatment success. The technique also is compared with an approach described in the literature. Two case reports are presented; the technique is employed in the first to close a diastema in a periodontally compromised dentition and in the second to correct the migration of maxillary and mandibular incisors. Photographs and radiographs show the esthetic improvement achieved in both cases using this technique.

Postoperative wound infection also called as surgical site infection (SSI), is a trouble some complication of lumbar spine surgeries and they can be associated with serious morbidities, mortalities and increase resource utilization. With the improvement in diagnostic modalities, proper surgical techniques, antibiotic therapy and postoperative care, infectious complications can result in various compromises afterwards. The objective was to study the relation of surgical site infection in clean lumbar surgeries with the doses of antibiotics. This Retrospective study was conducted at Shifa International Hospital, from January 2006 to March 2008. Methods: Hundred post operated cases of lumber disc prolapse, lumbar stenosis or both studied retrospectively by tracing their operated data from hospital record section for the development of surgical site infection (SSI). The patients were divided into three groups depending upon whether they received single, three or more than three doses of antibiotics respectively. Complete data analyses and cross tabulation done with SPSS version 16. Result: Of 100 cases, only 6% had superficial surgical site infection; only 1 case with co morbidity of hypertension was detected. Twenty-one cases had single dose of antibiotic (Group-I), 59 cases had 3 doses (Group-II) and 20 cases received multiple doses (Group-III). There was no infection in Group-I. Only one patient in Group-II and 5 patients in Group-III developed superficial SSI. While 4 in Group-II, 3 in Group-III, and none of Group-I had >6 days length of stay (LOS). Conclusion The dose of antibiotic directly correlates with the surgical site infection in clean lumbar surgeries. When compared with multiple doses of antibiotics a single preoperative shot of antibiotic is equally effective for patients with SSI. (author)
Full Text Available Geralmente o tratamento ortodôntico de pacientes adultos apresenta várias limitações, dentre as mais freqüentes podemos citar a perda exagerada do suporte ósseo, e a dificuldade de se obter uma ancoragem satisfatória devido às perdas de vários elementos dentários. No presente artigo, baseado na experiência clínica e na literatura consultada, procurou-se mostrar que é possível tratar de maneira eficiente esses casos, com uma abordagem multidisciplinar e adequação da mecânica ortodôntica à necessidade de cada indivíduo em particular. No caso clínico exposto, a paciente V.M., adulta, necessitava de tratamento odontológico envolvendo várias especialidades, incluindo a Ortodontia, que tinha como objetivo principal a intrusão e retração dos elementos 21 e 22. Após adequação do meio bucal, com a execução das extrações e restaurações necessárias, controle da doença periodontal e instituição de ótima higiene oral, foi iniciado o tratamento ortodôntico. Um sistema de ancoragem diferenciado foi aplicado, tentando superar a deficiência no número de unidades dentárias de suporte. Além disso, através da incorporação de "T-loops" aos arcos utilizados, procurou-se alcançar um bom controle na aplicação das forças necessárias à movimentação, evitando assim danos adicionais ao periodonto. Com esses cuidados, foi possível a obtenção de uma movimentação ortodôntica eficiente, com um real ganho funcional e estético para a paciente.Usually the orthodontic treatment of adults is quite limited, either in view of an exaggerated reduction in bone support, or due to the lack of anchoring points, when several dental elements having been lost. It is believed that these cases can be treated in an effective orthodontic way with a multidiscipline approach, tailored to each particular individual's mechanical needs. In this clinical case V.M, the patient, an adult, needed dental treatment involving several specialties
Since the introduction of the Tooth Positioner (TP Orthodontics) in 1944, removable appliances analogous to clear aligners have been employed for mild to moderate orthodontic tooth movements. Clear aligner therapy has been a part of orthodontic practice for decades, but has, particularly since the introduction of Invisalign appliances (Align Technology) in 1998, become an increasingly common addition to the orthodontic armamentarium. An internet search reveals at least 27 different clear aligner products currently on offer for orthodontic treatment. The present paper will highlight the increasing popularity of clear aligner appliances, as well as the clinical scope and the limitations of aligner therapy in general. Further, the paper will outline the differences between the various types of clear aligner products currently available. © 2017 Australian Dental Association.

To analyze the results of multiple Chinese orthodontic specialists' subjective evaluation of orthodontic treatment outcome, to investigate the relevance of different experiment items and to explore the weight of each monomial material. As a randomized clinical trial, with six orthodontic treatment centers and Angle's classification being regarded as two stratification factors, it contained 108 cases with integrity data, which was random extracted from 2383 cases that received orthodontic treatment in six orthodontic treatment centers during the past five years, gathering post-treatment study casts, cephalometrics and photographs of 48 cases as the research subject. Similarly taking Angle's classification as a stratification factor, 108 cases were randomly divided into 9 groups. The randomization of sampling and grouping were both generated by a pseudo-random number generator. According to the monomial and combined subjects, 69 orthodontic specialists were regarded as the raters to rank the 12 cases in each group, and to judge whether the case was qualified. Correlation analysis: the Spearman r between Post-M + C and Post-M + C + P and the Spearman r between Post-M + P and Post-M + C + P were both greater than 0.950. The Spearman r between Post-M and Post-P and the Spearman r between Post-M and Post-C were about 0.300. The Spearman r between Post-P and Post-C was 0.505. Regression analysis: the linear regression results: M + C = 0.782M + 0.308C - 0.150, M + P = 0.804M + 0.233P - 0.091, M + C + P = 0.764M + 0.243P + 0.131C - 0.291. The r(2) of above three models was greater than 0.9. It was applicable to use M + C and M + P instead of M + C + P. Study casts could not replace cephalometrics or photographs when doing subjective evaluation. Cephalometrics and photographs could not substitute for each other either. In the combined materials evaluation, model accounted for the largest percentage. Based on the regression model, for the greater part, the integration of

To correlate the mammographic and ultrasonographic findings with the pathologic results in women undergoing hormone replacement therapy (HRT), and to determine the characteristic clinical, mammographic or histologic findings of breast cancer in these patients. Twenty-five breast lesions in 25 patients aged 44-65 (mean, 55.5) years undergoing HRT were surgically removed due to abnormal mammographic findings or the presence of palpable masses. Mammograms in all patients and ultrasonograms in 23 were retrospectively analyzed in terms of the shape and margin of the mass, and microcalcifications, and the imaging findings were correlated with the pathologic results. As a control group, 45 cancer patients not undergoing HRT were selected. Using the student t test, detection methods, tumor size, mammographic findings, and the proportion of intraductal cancers were compared between to two groups. Surgical excision revealed ten benign lesions (four fibroadenomas and six cases of fibrocystic change) and 15 cancers (three intraductal and twelve invasive ductal cancers). Abnormal findings at mammography were a mass in 16 cases, clustered microcalcifications in seven, and a mass with microcalcifications in two. Mammography showed that all four circumscribed masses were benign. Five of seven ill-defined masses (71%) and all six spiculated masses were malignant. Three of seven cases (43%) with microcalcifications, and both with a mass and microcalcification, were malignant. In two cases in which ultrasonography revealed cystic lesions, histologic examination showed that fibrocystic change had occurred. Compared to non-HRT-related cancers, HRT-related cancers were more often detected by mammography (60% vs 16%; p<0.001), smaller (17 mm vs 24 mm, p<0.01), showed microcalcification only (20% vs 13%; p<0.05), and were intraductal (20% vs 7%; p<0.01). In patients with HRT, mammographic findings of an ill-defined or spiculated mass, or one with microcalcifications, were associated with

Full Text Available Mechanical trauma to the face may cause complex fracture of the zygoma and the maxilla. The characteristic clinical signs of zygomatic bone fracture include flattening of the cheek, infraorbital nerve paraesthesia, diplopia, and trismus, whereas maxillary fracture may typically cause flattening of the midface and malocclusion. The diagnosis of zygomatic and maxillary fracture should be established with thorough clinical examination and careful radiologic evaluation so that a three-dimensional view of the fractured bones can be obtained. This is essential in order to plan a proper surgical treatment to reconstruct the face in terms of functions and aesthetic. A standard surgical protocol should also be followed in performing the surgical reconstruction of the zygoma and the maxilla. A case of delayed bilateral fracture of zygoma and maxilla is presented here to give illustration on how the principle of diagnosis and surgical treatment of complex zygomatico-maxillary fracture are applied.
Mandatory Change From Surgical Skull Caps to Bouffant Caps Among Operating Room Personnel Does Not Reduce Surgical Site Infections in Class I Surgical Cases: A Single-Center Experience With More Than 15 000 Patients.
Shallwani, Hussain; Shakir, Hakeem J; Aldridge, Ashley M; Donovan, Maureen T; Levy, Elad I; Gibbons, Kevin J
Surgical site infections (SSIs) are noteworthy and costly complications. New recommendations from a national organization have urged the elimination of traditional surgeon's caps (surgical skull caps) and mandated the use of bouffant caps to prevent SSIs. To report SSI rates for >15 000 class I (clean) surgical procedures 13 mo before and 13 mo after surgical skull caps were banned at a single site with 25 operating rooms. SSI data were acquired from hospital infection control monthly summary reports from January 2014 to March 2016. Based on a change in hospital policy mandating obligatory use of bouffant caps since February 2015, data were categorized into nonbouffant and bouffant groups. Monthly and cumulative infection rates for 13 mo before (7513 patients) and 13 mo after (8446 patients) the policy implementation were collected and analyzed for the groups, respectively. An overall increase of 0.07% (0.77%-0.84%) in the cumulative rate of SSI in all class I operating room cases and of 0.03% (0.79%-0.82%) in the cumulative rate of SSI in all spinal procedures was noted. However, neither increase reached statistical significance ( P > .05). The cumulative rate of SSI in neurosurgery craniotomy/craniectomy cases decreased from 0.95% to 0.75%; this was also not statistically significant ( P = 1.00). National efforts at improving healthcare performance are laudable but need to be evidence based. Guidelines, especially when applied in a mandatory fashion, should be assessed for effectiveness. In this large, single-center series of patients undergoing class I surgical procedures, elimination of the traditional surgeon's cap did not reduce infection rates.

The aim of this retrospective study was to determine factors that might cause complications in use of temporary anchorage devices (TADs) for orthodontic anchorage. We investigated 904 TADs in 455 patients. Clinical diagnoses requiring orthodontic treatment were malocclusion, jaw deformity, various syndromes, cleft lip and palate and impacted teeth. All patients underwent surgery at Tokyo Dental College Chiba Hospital between November 2000 and June 2009. Three kinds of titanium screw of different diameter and length were used: self-drilling mini-screws (Dual Top Autoscrew® and OSAS®), pre-drilling micro-screws (K1 system®) and palatal screws (PIAS®). Mini-plates fixed with 2 or 3 screws (SAS system®) were also used for skeletal anchorage. Patients were aged between 8 and 68 years (25.7±9.8 years). A total of 460 screw-type and 444 plate-type TADs were used. These comprised the following: mini-plates, 444; self-drilling mini-screws, 225; pre-drilling micro-screws, 83; and palatal screws, 152. Each type of implant had a high success rate of over about 90%. Failure rates were as follows: micro-screws, 7%; mini-screws, 6%; palatal implants, 11%; and mini-plates, 6%. Inflammation rate occurring in soft tissue surrounding TADs was follows: plate-type, 7.6%; mini-screws, 1.3%; micro-screws, 0%; and palatal implants, 2.5%. Inflammation frequencies depended on degree of mucosal penetration. Granulation rate in soft tissue surrounding TADs occurred as follows: micro-screws, 5.7%; self-drilling mini-screws, 0%; palatal screws, 0.6%; plate-type, 0.9%. Both plate- and screwtype orthodontic implants showed excellent clinical performance.

To identify the risk factors for surgical site infection after cesarean delivery in a rural area in eastern Burkina Faso. A matched case-control study was conducted in Fada N'Gourma Regional Hospital Center and the Diapaga Medical Center with Surgical Antenna using data from 2011-2014. A total of 99 cases of surgical site infection after cesarean delivery were included in the study. Each case was matched with a control patient similar for age, admission date, and facility where the cesarean took place. Risk factors were identified using conditional logistic regression. Multivariate analysis identified hyperthermia at admission (OR 2.37; P=0.035), the presence of caput succedaneum in newborns (OR 7.07; P=0.001), and difficult delivery (OR 3.69; P=0. 019) as risk factors for surgical site infection. Provision of quality prenatal care, use of the partograph during labor, and the responsiveness of health workers during labor can reduce surgical site infection after cesarean delivery.

Full Text Available INTRODUCTION: This case report describes the orthodontic treatment of an adult patient with skeletal Class III malocclusion and anterior crossbite. A short cranial base led to difficulties in establishing a cephalometric diagnosis. The patient's main complaint comprised esthetics of his smile and difficulties in mastication. METHODS: The patient did not have the maxillary first premolars and refused orthognathic surgery. Therefore, the treatment chosen was orthodontic camouflage and extraction of mandibular first premolars. For maxillary retraction, the vertical dimension was temporarily increased to avoid obstacles to orthodontic movement. RESULTS: At the end of the treatment, ideal overjet and overbite were achieved. CONCLUSION: Examination eight years after orthodontic treatment revealed adequate clinical stability. This case report was submitted to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO as part of the requirements to become a BBO diplomate.

In this study, the author attempted to correlate clinical factors significant in cases of cervical myelopathy with postoperative recovery. It is hoped that the results will aid in the preoperative prediction of surgical outcomes. The factors considered were the transverse area of the spinal cord, the cord compression rate, the presence of a high intensity area in T2-weighted MRI, the duration of symptoms before surgery, and age at surgery. Because there are variations in the transverse area of the spinal cord, 100 normal individuals were selected and the standard transverse area was calculated. The transverse area of the spinal cord and the cord constriction rate in the myelopathy cases was then measured and compared to the standard. The data indicated that the constriction rate was most relevant to recovery rate. Clinical thresholds found to correlate with a better than average rate of recovery in cases of cervical spondylotic myelopathy (CSM) were: a cord constriction rate; under 28.7%, cord compression rate; over 0.38, duration of symptoms before surgery; less than 9.2 months, and age at surgery; under 59.2 yrs. In patients with ossification of the longitudinal ligament (OPLL), cord constriction rate; under 36.2%, cord compression rate; over 0.30, duration of symptoms before surgery; less than 14.2 months, and age at surgery; under 57.6 yrs., all correlated with superior recovery, as did cord constriction rate; under 22.3%, and duration of symptoms before surgery; less than 3.7 months with patients suffering from cervical disc herniation (CDH). Furthermore, the absence of a T2-weighted high intensity area in CSM and OPLL patients also correlated with improved recovery. These results suggest that a favorable postoperative recovery rate can be expected in cases of cervical myelopathy that conform to the above criteria. (author)

Otolaryngologists, dentists and maxilla-facial surgeons see patients suffering from odontogenic maxillary sinusitis on a daily routine. The study was performed to investigate the different origins of the odontogenic maxillary sinusitis ranging from periodontitis to augmentative implant surgery. Furthermore, the microbial flora of purulent odontogenic maxillary sinusitis was analyzed in order to present a proper antibiotic treatment in addition to a surgical approach. A retrospective study was performed, analyzing the clinical trials of 121 patients suffering from odontogenic maxillary sinusitis who undergone surgery. Harvested bacteria were tested for susceptibility on a routine base, surgical reports of removed foreign material or dental focus were reviewed as well as preoperative CBCT. Patients mean age was 56.62 (±16 SD) with a slight female gender dominance. Allergic profile to β-lactam antibiotics had no influence on patients' length of in-hospital stay. 69 out of 121 cases of OMS occurred after dental surgery (extractions, augmentation or implant surgery). Maxillary molars were the teeth mostly hold accountable for an onset without surgery in recent history. 22.3% of the patients possessed a dislocated foreign body in the maxillary sinus. Pseudomonas aeruginosa infection was significantly associated with misplaced foreign bodies (root filling, augmentative dental material e.g. p < 0.05). We protocoled an anaerobic dominance with 45 anaerobes versus 19 aerobes. Ampicillin/Sulbactam (80%) and Piperacillin/Tazobactam (93.3%) present sufficient susceptibly rates to the harvested bacteria. Likewise showed Moxifloxacin (86.3%) equal results, whereas Clindamycin had a poor outcome with merely 50% of the tested bacteria being susceptible to Clindamycin. If OMS is diagnosed dental focus should be treated, misplaced bodies should be removed and purulent exacerbation has to be additionally treated with a calculated antibiotic therapy according to the pathogens

The objective of this article was to present a surgical treatment option for teeth with incomplete vertical root fracture in maxillary and mandibular posterior teeth. Four cases are presented in which 1 endodontically treated maxillary or mandibular molar had an incomplete vertical root fracture involving 1 of the roots. The tooth underwent a flap elevation procedure to visualize the pattern of bone loss and assess the extent of root fracture. The fracture line was eliminated by resecting the root in a beveled manner, after which root-end preparation and root-end filling were performed by using mineral trioxide aggregate. The osteotomy was covered with an absorbable collagen membrane. Cases were followed up for 8-24 months after surgery. The procedure was shown to be predictable and successful in this series. Root length was preserved, and tooth extraction was avoided. The microsurgical treatment option for multirooted teeth with incomplete vertical root fracture resulted in long-term clinical success.

Recommendations for the operative treatment of spondylodiscitis are still a controversial issue. A retrospective review identified 113 consecutive patients who underwent surgical debridement and instrumentation for spondylodiscitis between 2006 and 2010 at our department. The mean age at presentation was 65 years; 78 patients were male (69 %). Distribution of the inflammation was lumbar in 68 (60 %), thoracic in 19 (17 %) and cervical in 20 (18 %) cases. Six patients (5 %) had two concomitant non-contiguous spondylodiscitis foci in different segments of the spine. Epidural abscess was found in 33 patients (29 %). One hundred four patients (92 %) had pain. Neurological deficit was found in 40 patients (35 %). In the thoracic and lumbar cases, dorsal instrumentation alone was considered sufficient in 26 cases; additional interbody fusion from the posterior was performed in 44 cases. A 360° instrumentation was performed in 22 cases. In the cervical cases, only ventral spondylodesis and plating were performed in eight cases, only dorsal instrumentation in five and 360° instrumentation in seven. Postoperative intravenous antibiotics were administered for 14.4 ± 9.3 (mean ± SD) days followed by 3.2 ± 0.8 (mean ± SD) months of oral antibiosis. Complete healing of the inflammation was achieved in 111 (98 %) cases. Two patients died because of septic shock, both with fulminant endocarditis. Pain resolved in all cases. Neurological deficits were completely resolved in 20 patients, and 14 patients had a partial recovery. The results of our retrospective study show that surgical treatment of spondylodiscitis with a staged surgical approach (if needed) and a short 1-2-week period of intravenous antibiotics followed by 3 months of oral antibiotics is appropriate for most patients in whom conservative treatment has failed or is not advisable. Furthermore, surgical treatment of newly diagnosed spondylodiscitis might be recommended as an initial treatment option in

Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

Orthodontic pain is an inflammatory pain that is initiated by orthodontic force-induced vascular occlusion followed by a cascade of inflammatory responses, including vascular changes, the recruitment of inflammatory and immune cells, and the release of neurogenic and pro-inflammatory mediators. Ultimately, endogenous analgesic mechanisms check the inflammatory response and the sensation of pain subsides. The orthodontic pain signal, once received by periodontal sensory endings, reaches the sensory cortex for pain perception through three-order neurons: the trigeminal neuron at the trigeminal ganglia, the trigeminal nucleus caudalis at the medulla oblongata and the ventroposterior nucleus at the thalamus. Many brain areas participate in the emotion, cognition and memory of orthodontic pain, including the insular cortex, amygdala, hippocampus, locus coeruleus and hypothalamus. A built-in analgesic neural pathway-periaqueductal grey and dorsal raphe-has an important role in alleviating orthodontic pain. Currently, several treatment modalities have been applied for the relief of orthodontic pain, including pharmacological, mechanical and behavioural approaches and low-level laser therapy. The effectiveness of nonsteroidal anti-inflammatory drugs for pain relief has been validated, but its effects on tooth movement are controversial. However, more studies are needed to verify the effectiveness of other modalities. Furthermore, gene therapy is a novel, viable and promising modality for alleviating orthodontic pain in the future.

Ankle joint fracture is one of the most common types of fracture. There are many researches on the injury mechanism, treatment principles and surgical techniques. A type of injury which combines posterior dislocation of fibula, known as the Bosworth injury, is relatively rare. In 1947, Bosworth first described this type of injury as an unusual ankle fracture dislocation with fixed posterior fracture dislocation of the distal part of the fibula. In this type of fracture, the proximal fibular shaft fragment locks behind the tibialis posterior tubercle. This rare ankle fracture variant is often not recognized in initial radiographs and requires a computed tomographic (CT) scan for verification. But there are already many reports, discussing the injury mechanism, treatment principles and surgical techniques. However, there are few reports of anterior dislocation of the fibula, caused by either injury or surgery. The mechanism of the injury is still not clear. This article reports a case of anterior dislocation of the fibula. We report a patient with left ankle open fracture (Lauge-Hansen pronation-external rotation stage III, Gustilo IIIA). Open reduction and internal fixation was done in the initial surgery, but ended up with poor reduction, resulting in fibula anterior dislocation, anterior dislocation of talus and tibia fibular dislocation. The fibula was dislocated anteriorly of the tibia, which rarely happened. The patient suffered severe ankle joint dysfunction. The second operation took out the original internal fixation, reduced the fracture, and reset the internal fixation. The function of ankle joint was improved obviously after operation. But because of the initial injury and the two operations, the soft tissue around the fracture was greatly damaged. 6 months after the second operation, and the fracture still not healed, so the bone graft was carried out in the third surgery. Two months after the third surgery, the function of the ankle was significantly

Little is known about the social and political factors that influence priority setting for different health services in low- and middle-income countries (LMICs), yet these factors are integral to understanding how national health agendas are established. We investigated factors that facilitate or prevent surgical care from being prioritized in LMICs. We undertook country case studies in Papua New Guinea, Uganda, and Sierra Leone, using a qualitative process-tracing method. We conducted 74 semi-structured interviews with stakeholders involved in health agenda setting and surgical care in these countries. Interviews were triangulated with published academic literature, country reports, national health plans, and policies. Data were analyzed using a conceptual framework based on four components (actor power, ideas, political contexts, issue characteristics) to assess national factors influencing priority for surgery. Political priority for surgical care in the three countries varies. Priority was highest in Papua New Guinea, where surgical care is firmly embedded within national health plans and receives significant domestic and international resources, and much lower in Uganda and Sierra Leone. Factors influencing whether surgical care was prioritized were the degree of sustained and effective domestic advocacy by the local surgical community, the national political and economic environment in which health policy setting occurs, and the influence of international actors, particularly donors, on national agenda setting. The results from Papua New Guinea show that a strong surgical community can generate priority from the ground up, even where other factors are unfavorable. National health agenda setting is a complex social and political process. To embed surgical care within national health policy, sustained advocacy efforts, effective framing of the problem and solutions, and country-specific data are required.

To determine clinical findings and outcomes for cats and dogs with peritoneopericardial diaphragmatic hernia (PPDH) treated surgically or nonsurgically. Retrospective case series. 28 dogs and 30 cats. Medical records for cats and dogs evaluated at 1 of 2 veterinary teaching hospitals were reviewed, and data regarding clinical signs, diagnostic and surgical findings, and outcome were evaluated. Prevalence of PPDH in the 2 hospitals during the study period was 0.025% (0.062% and 0.015% for cats and dogs, respectively); PPDH was an incidental finding for 13 (46.4%) dogs and 15 (50.0%) cats. Other congenital abnormalities were identified in 16 (571%) dogs and 7 (23.3%) cats (most commonly umbilical hernias, abdominal wall hernias cranial to the umbilicus, or sternal anomalies). Thirty-four (58.6%) animals underwent surgical repair of PPDH; 27 (79.4%) of these animals had a primary diagnosis of PPDH. Detection of clinical signs of PPDH (primary diagnosis) and intestines in the pericardial sac were significantly associated with surgical treatment. Short-term mortality rate for surgically treated animals was 8.8% (3/34). Clinical signs associated with PPDH resolved in 29 (85.3%) of surgically treated animals. No significant differences were detected between dogs and cats or between surgically and nonsurgically treated animals regarding long-term survival rate. Results of this study indicated animals with clinical signs of PPDH were more likely to undergo surgery than were animals without such signs. Herniorrhaphy was typically effective for resolution of clinical signs. Long-term survival rates were similar regardless of treatment method. Surgical or nonsurgical treatment of PPDH may be appropriate for animals with or without clinical signs, respectively.

To compare the use of the 810nm diode laser with conventional surgery in the management of soft tissue mucogingival problems associated with orthodontic treatment. Orthodontic patients requiring different soft tissue surgical procedures were randomly assigned to receive conventional surgery or soft tissue diode laser, (wavelength 810 nm). Parameters documented include the type of anaesthesia used, intra and post operative pain, bleeding, the use of scalpel and sutures. The chi-squared test was used to test for significance at 95% confidence level. Probability values (p-values) less than 0.05 were regarded as significant. Only 2(16.7%) of the procedures carried out with the soft tissue laser required infiltration anaesthesia compared to 10 (90.9%) with conventional surgery and this was significant (Pdiode laser (Pdiode laser. No sutures were used in all soft tissue cases managed with the diode laser and this was significant (Pdiode laser required less infiltration anaesthesia, had reduced bleeding during and after surgery, rapid postoperative haemostasis, elimination of the need for sutures and an improved postoperative comfort and healing.

Full Text Available Objective : Impaction of the third molar tooth mandibular is often found in patients with orthodontic treatment. In orthodontic treatment, extraction cases of impaction of the third molar tooth are usually performed, but the patients often refuse this extraction. Extraction of premolar has a good effect on the third molar mandibular angulation during treatment. Material and Methods : This study is a retrospective clinical study with descriptive analytic to find out the effect of the first mandibular premolar tooth extraction to angulation change of the third molar mandibular in orthodontic treatment with a standard edgewise method. Angulation change was performed by comparing the third molar mandibular angulation before and after orthodontic treatment with panoramic radiographs. Angulation of the third molar tooth mandibular was calculated from the angle formed between the long axis of the tooth with the reference line infraorbita. Results : The sample comprised 60 of impacted mandibular third molar region of the left and right regions of 30 patients who had been treated declared cured in clinic of orthodontic specialist of Dentistry Faculty Padjadjaran University. The sample was divided into three (3 groups of patients before treatment angulation of the third molar tooth mandibular under 300, 300 to 600 and above 60o, then measured change of angulation and observed whether it increased, fixed or decreased. Results were analyzed by T- test and Wilcoxon test showed that there was a significant change in angulation of the third molar mandibular in orthodontic treatment with the first premolar tooth mandibular extraction. Conclusion : This study is that the first premolar tooth mandibular extraction affects the angulation of the third molar tooth mandibular after orthodontic treatment.

Full Text Available Background and Objectives: Various extraction protocols have been followed for successful orthodontic treatment. The purpose of this study was to evaluate the extraction protocols in patients who had previously undergone orthodontic treatment and also who had reported for continuing orthodontic treatment from other clinics. Materials and Methods: One hundred thirty eight patients who registered for orthodontic treatment at the Faculty of Dentistry were divided into 10 extraction protocols based on the Orthodontic treatment protocol given by Janson et al. and were evaluated for statistical significance. Results: The descriptive statistics of the study revealed a total of 40 (29% patients in protocol 1, 43 (31.2% in protocol 2, 18 (13% in protocol 3, 16 (11.6% in protocol 5, and 12 (8.7% in Type 3 category of protocol 9. The Type 3 category in protocol 9 was statistically significant compared to other studies. Midline shift and collapse of the arch form were noticed in these individuals. Conclusion: Extraction of permanent teeth such as canine and lateral incisors without rational reasons could have devastating consequences on the entire occlusion. The percentage of cases wherein extraction of permanent teeth in the crowded region was adopted as a treatment option instead of orthodontic treatment is still prevalent in dental practice. The shortage of orthodontists in Malaysia, the long waiting period, and lack of subjective need for orthodontic treatment at an earlier age group were the reasons for the patient's to choose extraction of the mal-aligned teeth such as the maxillary canine or maxillary lateral incisors.

Bisphosphonates are a common medication for the prevention and therapy of osteoporosis, but are also applied for tumor diseases. They affect bone metabolism, and therefore also orthodontic treatments, but how it does has yet not been definitively clarified. Therefore, the aim of this research was to evaluate and demonstrate the reported effects and the current state of scientific research regarding orthodontic treatment and bisphosphonate medication exclusively in humans. A systematic research of the literature for selected keywords in the Medline database (Pubmed) as well as a manual search was conducted. The following search terms were used: 'Bisphosphonate' in combination with: orthodontic, orthodontic treatment, tooth movement. To date, only nine reported patients (case reports/series) and one original article (retrospective cohort study) regarding orthodontic treatment under bisphosphonate medication in humans have been published. Decelerated tooth movement with increased side effects (especially in high-risk patients) and longer treatment duration was reported in some articles. Patients with initial spacing or extraction cases had a higher risk of incomplete space closure and poor root parallelism. Orthodontic tooth movement under bisphosphonate medication is possible, especially in low-risk patients (low dose and short period of intake). But the treatment is still not predictable, especially in high-risk patients. Therefore, the altered bone metabolism and higher extent of side effects should be considered in treatment planning, especially in extraction cases or high-risk patients. Regardless, longer treatment duration, decelerated tooth movement, and more side effects, e.g., incomplete space closure and poor root parallelism, should be expected, especially in extraction cases or space closure.

Background Undergraduate orthodontic teaching has been focused on developing an understanding of occlusal development in an effort to equip practitioners to make appropriate referrals for specialist-delivered care. However, there is a growing interest among general dentists in delivering more specialised treatments, including short-term orthodontic alignment. This study aimed to assess the levels of knowledge of occlusal problems among final year undergraduate dental students, as well as their interest in various orthodontics techniques and training.Methods A 36-item electronic questionnaire was sent to all final year undergraduate students in four dental institutes in the UK (Barts and the London, Kings College London, Cardiff and Dundee). The questionnaire explored satisfaction with undergraduate orthodontic teaching; students' perception of knowledge, based on General Dental Council learning outcomes; perceptions of the need for specialist involvement in the management of dental problems; interest in further training in orthodontics; and potential barriers to undertaking specialist training.Results The overall response rate was 66% (239/362). The majority of students (84.1%) were aware of GDC guidance in terms of undergraduate teaching. Students reported a preference for case-based and practical teaching sessions in orthodontics, with less interest in lectures or problem-based learning approaches. A high percentage were interested in further teaching in interceptive orthodontics (60.3%) and fixed appliance therapy (55.7%). Further training including specialist orthodontic training (36.4%), Invisalign (59%) and Six Month Smiles (41%) courses appealed to undergraduates. Levels of student debt, course fees and geographical issues were seen as potential barriers to formal, specialist training pathways.Conclusions Satisfaction with undergraduate orthodontic teaching is high and interest in further training, including specialist training pathways, continues to be high

Tuberculate supernumerary teeth are found in the maxillary anterior region. They usually result in oral problems such as malocclusion, food impaction, poor aesthetics and cyst formation. There is paucity of literature on this anomaly in our environment. This paper describes a case of tuberculate supernumerary teeth with typical and atypical features of supernumerary teeth in this region. Treatment is carried out with a combination of surgical and orthodontic methods. Early diagnosis and treatment of this anomaly is suggested to avoid more serious consequences and to prevent severe orthodontic complications.

The aim of the study was to evaluate the influence of pre-treatment radiographic features (alpha-angle, d-distance and s-sector) on the duration of active orthodontic traction of impacted maxillary canines treated by a combined surgical (flap approach) and orthodontic (direct traction to the center of the ridge) treatment. A study population of 168 patients (168 canines) was evaluated. Multiple regression analysis was used. Pre-treatment radiographic variables were associated significantly with the duration of orthodontic traction. Age, gender and site of impaction did not affect the duration of traction significantly. Alpha-angle, d-distance and s-sector are valid indicators for the duration of orthodontic traction.
