Objectives-The aim of this study was to assess the applicability of sonography for evaluation of mandible bone healing after orthognathic surgery. Methods-The study included 10 patients who underwent orthognathic surgery. To assess new bone formation after sagittal split ramus osteotomy, the echo intensities of ultrasound (US) reflections of the proximal segment, distal segment, and bone gap were measured with a real-time US scanner at 1 day, 1, 2, 3, and 4 weeks, and 2 and 4 months postoperatively. Results-The mean echo intensity of US reflections of the bone gap gradually increased and became equivalent to that of bone surfaces by 4 weeks postoperatively. X-ray tomograms confirmed bone formation at the bone gap at the same time. Conclusions-This study indicates that sonography may be useful for evaluating osseous healing after orthognathic surgery.
