Abstract

PurposeTo determine intraoperative as well as post surgical complications of bilateral sagittal split ramus osteotomy. Patients and methodsA retrospective evaluation of 44 case records of BSSRO, performed over a period of five years from January 2010 to Dec 2014, at a single center. ResultsBad split was reported in 3 patients in the series, intraoperative bleeding was encountered in 5 cases, which was controlled by pressure packing. Postsurgical Neuro Sensory Deficit (NSD) was present in 22 patients, which resolved over a period of 6 months–1 year. Severe relapse and bone loss were reported in 1 patient each. Implant removal was done in 3 cases following peri-implantitis. Reoperation was done in 1 case to correct anterior open bite (AOB). ConclusionNeuro Sensory Deficit (NSD) was the most common immediate post surgical complication following BSSRO. Almost all the cases had neuropraxia of inferior alveolar nerve (IAN) secondary to stretch or compression. Additional care should be taken during incision placement, soft tissue retraction and fixation.
