Analysis of Soft Tissue Changes after Genioplasty in Skeletal Class Ⅲ Dentofacial Deformity

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study was to measure the anteroinferior changes and the degree of vertical changes to
facilitate the prediction of treatment outcome in patients undergoing genioplasty only, genioplasty with bilateral
sagittal split ramus osteotomy (BSSRO), genioplasty, or BSSRO and Lefort I osteotomy. Materials and Methods:
Serial cephalometry was performed on 25 patients at 1-year follow-up after genioplasty, to assess skeletal changes
and relapse. Surgery was performed using conventional techniques. Results: The mean ratio was 0.9 : 1 of soft
tissue to skeletal movement at pogonion, but the average difference between hard and soft tissue was large; thus, the
prediction of anteroposterior soft tissue changes was quite inaccurate. Conclusion: We observed a good correlation
between the amount of hard versus soft tissue change with surgery in the horizontal direction, but a poor correlation
in the vertical plane.
