The aim of this retrospective study was to identify the significant risk factors that contribute towards postoperative infection in patients recovering from orthognathic surgery. 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. 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

BACKGROUND: Orthognathic surgery involves movement of jaws in all three planes, and this being a part of airway complex, displacement of jaws can influence the dimension of airway at all levels. Lefort one osteotomy surgery with superior repositioning is a common procedure done for patients with vertical maxillary excess PURPOSE: The purpose of this study was to evaluate the three-dimensional volumetric changes in airway after lefort one impaction surgery using three-dimensional cone beam computed tomography (3D-CBCT) in patients with vertical maxillary excess (VME). METHODS: A prospective analysis of 15 patients who underwent isolated lefort one impaction surgery was done with pre-operative (T0) and 3-months (T1) post-operative 3D-CBCT scans. Airway was divided into three segments, nasopharyngeal, velopharyngeal and oropharyngeal. Volumetric analysis of all these segments was done before and after surgery. Paired ‘t test’ was used to assess the mean difference in airway volume and area between T0 and T1. One-way ANOVA was used to check the mean percentage difference in airway volume and area among the three segments. RESULTS: The mean percentage of nasopharyngeal volume difference was − 0.6299 ± 0.9146%, velopharyngeal volume difference was − 0.5205 ± 1.107%, oropharyngeal volume difference was − 1.492 ± 2.745%. Though volume and area of pharyngeal airway were decreased after maxillary impaction surgery in all three segments of airway studied, they were not statistically significant. CONCLUSION: Among the three segments of airway studied, oropharyngeal airway volume has shown the highest post-surgical reduction though statistically insignificant. ESS scores were within normal limits. Hence, we are of the opinion that there is lack of evidence to conclude that the patients undergoing lefort one superior repositioning for the treatment of VME might develop significant narrowing of PAS that may predispose the patient to breathing disorders.

Aim of this study was to evaluate the split skin graft held in place with a polyethylene stent for the treatment of oral submucous fibrosis.Fifteen prospective patients diagnosed clinically with oral submucous fibrosis, from June 2011 to 12 December 2012, were recruited for this study. All patients were treated surgically using the same surgical technique of fibrotomy followed by split skin graft along with a polyethylene stent. Preoperative and postoperative mouth opening measurements at 1 week and after a minimum of 6 months were evaluated by measuring the inter incisal distance.Mean follow up was 9.8 months with a minimum of 6 months. Mean preoperative mouth opening was 12.9 mm (6-20 mm). Intraoperatively mean mouth opening was 37.9 mm (36-41 mm). After 1 week mean mouth opening was 35.8 mm (31-40 mm). At 6 months follow up, mean mouth opening was 33 mm (20-40 mm).Fibrotomy followed by split skin graft along with a polyethylene sheet stent and sufficient postoperative physiotherapy is a simple, cost effective and viable treatment modality for oral submucous fibrosis.
