영문 초록

The purpose of this study is to evaluate the changes of the soft tissue relative to the inderlying skeletal and dental elements before and after orthognathic surgery for the correction of the prognathic mandible, and the influence of the orthognathic surgery quantitatively on the various regions of the facial profile. 11 patients were selected (6 men and 5 women), who had received orthognathic surgery for the correction of their prognathic mandible, and the mean age was 20.5 years. Lateral cephalometric head films were taken before and after surgery. The results were obtained as follows: 1. The ratio of horizontal changes of hard tissue to soft tissue at pogonion, mentolabial sulcus, and lower lip were almost 1:1. 2. 1 ㎜ of change at Pog resulted in 0.97 ㎜ at Pogs, 0.90 ㎜ at Bs, and 0.65 ㎜ at Li. 3. There were little changes at the depth of mentolabial sulcus and relative upper lip protrusion, but nasolabial angle was increased (average 0.18˚) and relative lower lip protrusion was decreased (average -1.45 ㎜). There was no significant correlation with the changes of hard tissue landmarks. 4. The lower anterior facial height of hard tissue (ANS-Gn) and soft tissue (Sn-Mes) was decreased, but there was no significant correlation between the changes.
