Description

The purpose of this study was to clarify the correction of facial asymmetry through the orthognathic surgery. The subjects were operated by bilateral sagittal splitting ramus osteotomies (SSRO group) and the unilateral sagittal splitting ramus osteotomy combined with the body ostectomy (SSRO-BODY group). Skeletal and soft tissue outlines were obtained from the frontal cephalogram before and after surgery. These outlines were normalized, and changes of those outlines in the two groups were compared with each other.<BR>As for soft tissue outline, asymmetry of both groups were corrected much better after surgery.<BR>In skeletal outline of the SSRO group, there were significant changes in the region of bilateral mandibular angle after surgery, but change of the outline was a little on the deviation side. In the SSRO-BODY group, however, outline in regions of bilateral mandibular angle and ramus on the deviation side changed significantly after surgery. Facial asymmetry seemed to be corrected much more in the SSRO-BODY group than the SSRO group.
