Abstract
This study evaluated the postoperative stability following intraoral vertical subsigmoid osteotomy (IVSO) and bilateral sagittal splitting ramus osteotomy (BSSO) in skeletal Class III patients. The subjects were skeletal Class III patients without asymmetry divided into two equal groups, six patients in each group, where the operative method (IVSO or BSSO) applied to bilateral site for mandibular setback, lateral cepahalometric radiographs were taken at three times intervals, (T0) immediately before surgery, (T1) immediate after surgery, and (T2) 6 months after surgery. There was no statistically significance in skeletal stability in both groups in vertical and horizontal planes. However, the neurosensory deficit was significant in BSSO group
