Schwannomas are benign nerve tumors of schwann cell origin. Schwann cells are derived from neural crest and are therefore of neuroectodermal origin. 25-40% of all schwannomas arise in the head and neck region. The most common schwannomas are vagal schwannomas and cervical schwannomas in the head and neck region. Here we present two cases of head and neck schwannomas which were not identified as originating from any major nerve. The first patient had a schwannoma in the infratemporal region which was excised by performing transzygomatic approach, and the second patient had a schwannoma in the left lateral part of the neck which was excised using a cervical crease incision., Competing Interests: Conflict of interestThe authors that they have declare no conflict of interest., (© The Association of Oral and Maxillofacial Surgeons of India 2022.)

Purpose: The aim of this study was to analyze and compare the healing of scalpel and diathermy incision wounds in the oral mucosa., Materials and Methods: This is a prospective split-mouth study conducted from January 2015 to April 2017 among patients undergoing either Le Fort I or anterior maxillary osteotomy (or both). The study groups were classified based on the different techniques used to make the incision (group A, incision made by a scalpel; group B, incision made by diathermy). Wound healing was assessed on the first, third, seventh, and tenth postoperative days using the Southampton scoring system. Data were statistically analyzed using the Student t test for continuous variables and the χ 2 test for categorical variables, and P < .05 was considered significant., Results: Among the 113 participants included in the study, the age range was 16 to 35 years and male patients comprised 50.4%. The rates of postoperative complications of wound healing were 68.1% (n = 77) in group A and 77% (n = 87) in group B. Wound healing showed a statistically significant difference between the techniques (P < .001)., Conclusions: The findings of this study suggest that wounds caused by scalpel incisions healed better than those caused by diathermy incisions in the oral mucosa., (Copyright © 2018 American Association of Oral and Maxillofacial Surgeons.

Objective: The aim of this retrospective study was to identify the significant risk factors that contribute towards postoperative infection in patients recovering from orthognathic surgery., Methods: Retrospective records of 522 patients who underwent orthognathic surgery over 9 year period were evaluated for postoperative infection within 3 months of surgery and after 3 months of surgery. The variables of interest included age, gender, habits like smoking and alcohol consumption and incidence of postoperative infection., Results: The overall infection rate was 4.60%. Patients who underwent bilateral sagittal split osteotomy to advance the mandible had an infection rate of 10.4%. Statistically significant predictor variables ( P  < 0.05) included patients who had the smoking habit, and those that received bone grafts in both the time periods., Conclusion: In conclusion, the occurrence of infection after orthognathic surgery is influenced by multiple factors, among which are the type of osteotomy, smoking habit and bone grafting procedures.
