A modified sagittal split osteotomy: description of technique

The mandibular ramus bilateral sagittal split osteotomy (BSSO) is the common approach in orthognathic surgery; however, this design has some limitations to achieve a good definition angle of jaw Class II patients with decreased posterior facial height. This paper aims show novel modification and its technic description conventional BSSO which increases vertical length angle, two similar diagnosis one-year follow-up. In conclusion, modified result conjunction techniques (BSSO chin wing osteotomy), that useful who benefit from improvement projection mandible increase Future studies involving long-term follow-up are needed evaluate permanence these results.
