Abstract
Nowadays bilateral sagittal split osteotomy (BSSO) is the most common technique for treatment of mandibular skeletal deformities. One of the most sensitive stages in BSSO is recognition of inferior alveolar nerve entrance. This technical note presents a noble and safe approach for medial osteotomy in BSSO which is based on anatomy of mandible during the surgery. In this approach osteotomy initiates at the junction of buccal and lingual cortices of ramus and will continue parallel to buccal cortex and in the same direction with sagittal cut. Compared to conventional BSSO technique, less neurosensory complications, risk of condylar sagging and bad splitting are expected in suggested modification. The operation time, healing and recovery periods are shorter, which cause more convenience for both surgeon and patient.
