A modification of the sagittal splitting technique ensuring that the osteotomy split lies immediately medial to the lateral cortex.
A modification of Obwegeser's sagittal splitting method for the correction of mandibular prognathism has been developed. The anterior border of the proximal segment is partially removed at the beginning of osteotomy, which is carried out on the immediate inner surface of the lateral cortex. This osteotomy plane just under the lateral cortex, obtained by the use of a thin, disposable reciprocating sawblade, contributed to a lower incidence of postoperative lower lip hypaesthesia in the 14 cases presented.
