Abstract:
Objective: To observe the postoperative skeletal changes of mandibular setback via bilateral sagittal ramus split osteotomy (BSSRO) with circummandibular wiring and maxillomandibular fixation. Methods: BSSRO was performed in 14 cases to setback the mandible. The patients were followed up for 6 months by clinical observation and examined with lateral cephalometric radiographs and Schuller's position radiographs before and after surgery. Results: According to the measured parameters the ralapse extent was 27.2%. Multiple regression analysis showed the magnitude of the setback significantly accounted for relapse (P
