A new surgical approach to correcting mandibular prognathism in Oriental patients: report of two cases.

Surgical procedures had been used for the reduction of mandibular prognathism to achieve improved function and aesthetics. However, in Oriental patients mandibular prognathism was often present together with maxillary protrusion. Mandibular set-back surgery alone could not achieve the desired aesthetics in such patients. This report describes a surgical approach involving both maxillary subapical osteotomy and mandibular set-back surgery to correct the problem. This new surgical procedure not only produced optimum aesthetics but achieved the desired results in the shortest possible time.
