Abstract:
Bilateral sagittal split ramus osteotomy (BSSRO) is commonly used to correct mandibular prognathism or retrognathism. Patients with mandibular prognathism or retrognathism may also present with a prominent mandibular angle. In this paper, we share our experience on BSSRO with mandibular angle resection. Eleven patients who were treated from July 2014 to December 2016 were included in this study. The mandibular angle was resected through the medial side of the mandible after BSSRO. The mandibular angle measurements of the patients changed significantly after surgery (p < 0.05). Unanticipated fractures and mandibular hematoma did not occur. Therefore, BSSRO combined with mandibular angle ostectomy through the medial side of the mandible can be used to safely and effectively correct facial deformity.
