Orthognathic surgery was performed on a total of 118 patients from 1989 to 1995 in our clinic. The ratio of male to female was 1: 2.2 and the mean age was 20.6 years. In most of the patients (95.7%), mandibular prognathism with or without another type of jaw deformity was diagnosed. Sagittal splitting ramus osteotomy (SSRO) was performed on 113 patients (95.8%). The average time of operation and the average blood loss during operation were 3 hr 47min and 558.2ml for SSRO and 6 hr 44min and1090 ml for two jaw surgery, respectively. Fixation of the bone fragment for SSRO was done asfollows: 58 patients by semi-rigid fixation with titanium miniplate, 50 patients by circumferential wiring, and 5 patients by other methods. The average period of intermaxillary fixation in SSRO was 8.2 days for miniplate fixation and 20.2 days for circumferential wiring. Seventy-five of 90patients (76.3%) who received blood transfusion received autotransfusion.
