Reverse sagittal split of the mandibular ramus for an unusual deformity

A reverse sagittal split osteotomy of the mandible for advancement or retraction of the mandible is described to be used in selected instances when the transoral modified sagittal ramus osteotomy would probably result in a pathologic fracture or an inadequate proximal segment. This procedure provides the same benefits as does the modified sagittal split osteotomy. A disadvantage of the procedure is that it requires both intraoral and extraoral incisions.
