The study of soft tissue changes in orthognathic surgery patients

The analysis of soft tissue profile is an important paramenter in the esthetic aspect of facial deformity correction. The authors have studied on the soft tissue changes after the orthognathic surgery. We grouped the 30 patients according to the operation methods ; group 1 S.S.R.O. only, group 2 S.S.R.O.+Genioplasly, group 3 LeFortⅠ+S.S.R.O. The results were obtained as follows ; 1. In Group 1, the ratio of horizontal changes of hard tissue to soft tissue at 1 to Stmi, B to Si, Pog/SPog is 1.09, 0.96, 1.12 with postop. immediately, 0.98, 0.89, 0.98 with postop. 6 months. 2. In Group 2, the ratio of horizontal changes of hard tissue to soft tissue at 1/t Stmi, B/Si, Pog/SPog is 1.09, 1.11, 1.12 with postop. immediately, 0.92, 0.88, 0.99 with postop. 6 months. 3. In Group 3, the ratio of horizontal changes of hard tissue to soft tissue at A to Sn, 1 to Stms, B to Si, Pog to SPog is 1.15, 1.09, 1.15, 0.89, 1.05 with postop. immediately, 0.98, 0.94, 0.99, 0.90, 0.93 with pstop. 6 months.
