Planning the surgical treatment of mandibular prognathism]

The method for calculating a required displacement of the mandible posteriorly in surgical treatment of prognathism by the technic of oblique osteotomy of the mandibular branches is suggested. The described technic was successfully employed by the author in 56 patients. The technic concerned would reduce the time of a surgical procedure (up to 50-60 min). The main advantage of the technic is that it completely excluded errors in calculating the displacement of the mandible posteriorly.
