Sagittal split osteotomy in our experience. A follow-up study of 100 operated patients.

Sagittal split osteotomy is a tricky and time-consuming operation but gives excellent mobilization of the mandibular body for the purpose of positional changes. A follow-up study of 100 operated patients up to 3 years and more has demonstrated good and stable occlusion and subjective appraisal of improvement in appearance and bite. Negative effects of the operation are injuries to the inferior avleolar and lingual nerves.
