摘要： 目的观察女性下颌角截骨术后面部软组织的变化情况。方法将130例行下颌角截骨术(口内切口)的女性下颌角肥大患者纳入本次研究,通过CT、成像软件测量术前及术后6个月面部软组织①耳垂点至下颌角高度与下面高度的比值②正位双下颌角间距与双颧间距比值③软组织下颌角角度,观察手术前后中下面部软组织的变化。结果术前耳垂至下颌角高度与下面高度比值为1∶(1.5±0.12),术后为1∶(1.92±0.15);术前正位双下颌角间距与双颧间距比值为1∶(1.03±0.11),术后为1∶(1.2±0.21);术前下颌角角度为(109±1.7)°,截骨术后下颌角角度为(121±2.1)°。结论下颌角肥大患者行下颌角截骨术约6个月后,中下面部软组织外形改善明显。

Abstract: Objective To observe the change of facial soft tissue after mandibular angle osteotomy. Methods Comuterized tomography (CT) examination was performed on 130 patients treated by mandibular angle ostemomy before operation and 6 months after operation, respectively. Intra-oral incision were used for correcting prominent mandibular angle (PMA).①ratio of the height from lobule to mandibular angle&the height of lower face, ②ratio of the distance between the two sides of mandibular angle&the distance between the two sides of zygometic arch and ③the degree of mandibular angle were all calculated pre-and postoperatively to evaluate the change of facial soft tissue. Results The preoperative ratio of the height from lobule to mandibular angle&the height of lower face was 1∶(1.5±0.12), while the postoperative was 1∶(1.92±0.15);The preoperative ratio of the distance between the two sides of mandibular angle & the distance between the two sides of zygometic arch was 1∶(1.03±0.11), while the postoperative was 1∶(1.2±0.21);The preoperative mandibular angle was (109±1.7) °, while the postoperative was (121 ±2.1) ° . Conclusion Six months after mandibular angle osteotomy, the patients with mandibular angle hypertrophy could obtain better quantitative improvement of facial shape.
