Study Design For certain condylar fractures, extracorporealization of the condylar segment may be performed via extra-oral vertical ramus osteotomy (EVRO) to facilitate reduction and fixation. This approach can similarly be used for condyle-sparing resection of osteochondromas of the condyle. Due to controversy regarding long-term health of the condyle after extracorporealization, we conducted a retrospective analysis of surgical outcomes. Objective For certain condylar fractures, extracorporealization of the condylar segment may be performed via extra-oral vertical ramus osteotomy (EVRO) to facilitate reduction and fixation. This approach can similarly be used for condyle-sparing resection of osteochondromas of the condyle. Due to controversy regarding long-term health of the condyle after extracorporealization, we investigated the viability of this technique through a retrospective analysis of outcomes. Methods Twenty-six patients were treated using EVRO with extracorporealization of the condyle for both condylar fractures (18 patients) and osteochondroma (8 patients). Of the 18 trauma patients, 4 were excluded due to limited follow-up. Clinical outcomes were measured, including occlusion, maximum interincisal opening (MIO), facial asymmetry, incidence of infection, and temporomandibular joint (TMJ) pain. Radiographic signs of condylar resorption were investigated, quantified, and categorized using panoramic imaging. Results Average follow-up was 15.9 months. Average maximum interincisal opening was 36.8 mm. Four patients demonstrated mild resorption and one patient demonstrated moderate resorption. Two cases of malocclusion were attributed to failed repairs of other concurrent facial fractures. Three patients reported TMJ pain. Conclusions Extracorporealization of the condylar segment with EVRO to facilitate open treatment of condylar fractures is a viable treatment option when more conventional approaches prove unsuccessful.

Purpose Takotsubo syndrome (TS) is an acute and potentially serious cardiac disorder that is often attributed to an exuberant catecholaminergic response to a severely physical or emotional event. As there is a paucity of information in the dental literature on TS, this article will provide an overview of this uncommon syndrome, including clinical presentation, demographic characteristics, etiopathogenesis, diagnosis, management, and recovery, particularly emphasizing its occurrence with oral and maxillofacial procedures. Patients and Methods A PubMed search with the keyword “takotsubo” for publications from 1991 through May 2018 yielded 3,778 articles. Case reports and case series of TS associated with surgical and nonsurgical procedures in the oral and maxillofacial region were reviewed. Other cases were identified using a defined search strategy. Results The literature search identified 28 documented episodes of TS that occurred with head and neck surgical procedures, mostly sinus, carotid, nasal, and cancer reconstruction surgical procedures, and notably, 3 cases occurred concurrently with dental extractions. In all of the featured patients, some degree of cardiovascular impairment developed and phenotypic overlap with acute occlusive coronary disease was shown. Most patients recovered within 2 weeks, and recovery in the remainder extended up to 3 months. Conclusions On rare occasions, TS has been reported in association with oral and maxillofacial procedures. As stress appears to be a precipitating factor in the development of TS, perioperative efforts should be instituted to reduce an adrenergic cascade.

Numerous incisions around the ear have been described, and many have been used in oral and maxillofacial surgery for procedures involving the temporomandibular joint (TMJ), condylar neck, and parotid gland, as well as for rhytidectomy.1-5 Although the traditional preauricular and endaural incisions will frequently provide an excellent outcome, they will heal with a visible scar.1,4 The incision we have described aims to refine the incision to further improve this esthetic outcome. Additionally, surgical procedures around the ear have often resulted in the unpleasant and inconvenient collection of blood or surgical skin preparation in the ear canal. Although not recorded in reported studies, in our experience, patients have commonly complained of "blocked ears" for 1 to 2 weeks in the postoperative period. Although this complication represents minimal risk, it can often be difficult, once clotted or dried, to remove and will be bothersome to the patient. In addition, any packing placed in the external auditory canal (EAC) intraoperatively to mitigate the collection of blood will often and repeatedly dislodge from the EAC, requiring replacement multiple times during the procedure to the frustration of the surgeon. The techniques we have described are 2 straightforward, but innovative, surgical techniques that refine surgery around the ear to improve the esthetics and patient comfort, facilitate the surgical procedure, and increase reliable anatomic access. The modified incision we have described is predominately aimed at operations requiring access to the TMJ, condylar neck, or parotid gland. The techniques were, to the best of our knowledge, first used in our unit at the University of Maryland.

Purpose The purpose of this study was to estimate the penetration of cone-beam computed tomography (CBCT) in oral and maxillofacial surgery (OMS) residency programs in the United States. In addition, this study was designed to assess the education and training, relevance, and image interpretation responsibility of CBCT as experienced by OMS residents. Materials and Methods The authors performed a cross-sectional study of all 102 US-based OMS program directors (PDs) from January 1, 2014 through April 30, 2014. Study variables included questions about 4 key factors in CBCT in OMS programs: access, education and training, relevance, and image interpretation responsibility. Data analysis was a product of the percentage of positive responses to each question. Results Fifty-four PDs participated in the study. The results showed that 87% of responding OMS programs have access to CBCT and that CBCT is used primarily for dental implant-related procedures. Conclusion OMS residents are actively involved in CBCT use in their residency. OMS residents' access to CBCT is increasing, and their education, training, and image interpretation responsibility is increasing.

There is no clinical consensus for the treatment of Keratocystic Odontogenic Tumor (KCOT). KCOTs are regarded as benign aggressive tumors and resection is usually considered as a last option. We review the clinical indications for resection based on a case series.This is a retrospective study of patients with KCOT treated in a single unit over 17 years. Eighty patients were identified, of which 12 (15 %) underwent resection. The remaining 68 patients were managed by enucleation and curettage, enucleation with peripheral ostectomy, or decompression with secondary enucleation. Data extracted includes gender, age, race, location, previous treatment for the lesion, surgery and outcome/follow up.Twelve patients treated by resection were identified. The location in the ten benign resected KCOTs was either the mandibular ramus or the posterior maxilla. All mandibular KCOTs exhibited perforation of the lingual plate and involvement of the pterygoid musculature. Seven of the ten cases were recurrent KCOTs and three had no prior treatment. Two had malignant changes in the KCOT and were also resected.The primary reason for resection of KCOT was involvement of the pterygoid muscles. The presence of malignant change was a separate indication for resection.

Purpose Lymph node metastasis from oral squamous cell carcinoma (SCC) correlates with a poor prognosis. Therefore, accurate assessment of lymph node status is crucial in treatment planning. Furthermore, prediction of delayed neck metastasis (DNM), especially in early stage tumors with a clinically negative (N0) neck, will determine the need for neck dissection or irradiation. In this study, we assess various clinical, histopathological and lymphangiogenic parameters in early stage oral SCC and their association with DNM. Materials and Methods Clinical, histological, and immunohistochemical analyses were undertaken for 29 patients with T1N0M0 or T2N0M0 oral SCC affecting the tongue or floor of mouth and correlated with the development of DNM. Results Tumor thickness, nuclear pleomorphism, pattern of invasion, and immunohistochemical expression of the lymphangiogenesis-associated molecules VEGFR-3 and VEGF-C were associated with DNM. Conclusions Analysis of these parameters may help to identify patients who would benefit from a neck dissection or irradiation by predicting the likelihood of lymph node metastasis.

with an odds ratio of 2.7173 (95% confidence interval(CI), 1.0995-6.7151). IgG FcgRIII(NA) was slightly associated with the frequency of the NA2 allele (p 0.1001) with an odds ratio of 1.6086 (95% CI, 0.91062.8413), showing no significant differences. No significant results were obtained for the remaining 12 genes. Conclusion: The variation of TNFRII( 587)T/G affected tumor necrosis factor-alpha induced apoptosis, and was associated with systemic lupus erythematosus, rheumatoid arthritis and severe chronic periodontitis. These results suggested that TNFRII( 587) genetic polymorphism was useful as the sensitivity marker in OLP.
