영문 초록

From the patient s standpoint, the result of orthognathic surgery will mainly be judged by the soft tissue configuration obtained. The prediction of soft-tissue changes following orthognathic surgery is very important to plan a successful treatment. To aid In prediction of postoperative upper lip and nose position following maxillary orthognathic surgery, retrospective investigation of soft-tissue changes associated with maxillary advancement (Le Fort Ⅰ osteotomy) was performed. The following conclusions were drawn. 1) Soft tissue landmarks (Pn, Sn, Ls) moved in a anterior and superior directions following maxillary advancement. 2) The mean ratio for hPn/hANS is 0.2±0.15. The mean ratio for vPn/hANS is 0.15±0.13 3) The mean ratio for hSn/hA is 0.54±0.14 The man ratio for vSn/hA is 0.15±0.05 4) The mean ratio for hLs/hPr is 0.64±0.20 The mean ratio for vLs/hPr is 0.2±0.16 5) A progressive increase in the horizontal soft-tissue movement from the tip of the nose (Pn) to the free end of the upper lip was observed. 6) A decrease in lip thickness was observed with a mean of -1.4㎜ at A point.
