Abstract
We observed 117 orthognathic surgery cases with dentofacial deformity for 8 years from Jan. 1986 to Dec. 1993. The ratio of male to female was 1 : 14 and the mean age was 23.0 years ranged from 16 to 35 years. The most dominant group was related
to
mandibular prognathism(75.0%).
Surgery method were divided into 88 cases of mandible surgery, 6 cases of maxilla surgery and 23 cases of two jaw surgery. Sagittal split osteotomy were performed on 84 cases (71.8%). Rigid fixation was increased after 1989 and total percent of
rigid
fixation was 66%. We used autotransfusion method from 1992 to all orthognathic surgery patient.
Lower lip numbness caused by Inferior alveolar nerve injury is the most common problem after operation, and it was 63 cases (53.8%) of total operation cases. In our clinic, we performed 5 cases of re-operation because of segment malalignment,
