Postoperative mandibular stability after bilateral sagittal split ramus osteotomy based on skeletal correction in patients with facial asymmetry

The objective of this study was to examine postoperative stability of the mandible after bilateral sagittal split ramus osteotomy (BSSRO) based on skeletal correction rather than occlusal correction in patients with facial asymmetry. Eighteen patients with facial asymmetry were enrolled in this study. BSSRO was performed, and an intermaxillary mandibular repositioning splint was prepared using a newly developed surgical simulation system...
