摘要/Abstract

摘要： 目的探究骨性Ⅲ类错畸形患者双颌手术后面部各区域软组织的变化特点。方法 2017—2019年于我院就诊的18例骨性Ⅲ类错畸形患者，男女各9例。使用3dMD摄影测量系统分别于双颌手术前一周内任一天和术后6个月拍摄患者面部图像，并通过Geomagic Qualify软件对手术前后的面部图像进行三维重建和匹配，分割各个面部区域，得出面部各区域软组织的变化量。结果术后颞区（R1）软组织改变量为-0.17 mm,颧弓区（R4）为-0.42 mm,下口角旁区（R11）为-0.81 mm，下唇及颏区（M3）为-3.08 mm，呈负向改变（P＜0.05）；眶下区（R2）软组织改变量为0.29 mm，鼻翼旁区（R5）为1.58 mm，上口角旁区（R8）1.08 mm，鼻区（M1）为0.59 mm，上唇区（M2）为2.05 mm，呈正向改变（P＜0.05）；左右两侧相同面部区域的软组织变化无统计学差异（P>0.05）；同区域男性与女性的软组织变化差异无统计学意义（P>0.05）。结论骨性Ⅲ类错畸形患者双颌手术后颞区、颧弓区、下口角旁区、下唇及颏区的软组织变得凹陷，而眶下区、鼻翼旁区、上口角旁区、鼻区、上唇区的软组织变得凸出。术后左右侧相同面部区域的软组织改变无差异，性别对术后面部各区域软组织的改变没有影响。

Abstract: Objective　 To explore the characteristics of soft tissue changes in different facial areas after maxillofacial surgery in patients with skeletal Class III malocclusion. Methods　 Eighteen cases of skeletal Class III malocclusion in our hospital from 2017 to 2019,9 cases of male and female. Using 3dMD photogrammetry system, the facial images of the patients were taken on any day of the week before and 6 months after the surgery. The facial images before and after the operation were reconstructed and matched by Geomagic Qualify. Then the changes of soft tissue in each area of the face were obtained. Results　 The changes of soft tissue after operation were -0.17 mm in temporal region (R1), -0.42 mm in zygomatic arch area (R4), -0.81 mm in under the mouth next district (R11)and -3.08 mm in lower lip and chin area (M3). Negative changes happened in the above regions (P<0.05); The soft tissue changes were 0.29 mm in infraorbital region (R2), 1.58 mm in paranasal area, 1.08 mm in on the mouth next district (R8), 0.59 mm in nasal region (M1),and 2.05 mm in superior labial region (M2) . Positive changes happened in the above regions (P<0.05). Soft tissue changes in both sides of the same facial area were not significantly different (P>0.05); and the differences between men and women in soft tissue changes of the same region had no statistical significance (P>0.05). Conclusions　 The soft tissue of patients with skeletal Class III malocclusion in temporal region, zygomatic arch area, under the mouth next district, lower lip and chin area became depressed after bimaxillary surgery, while the soft tissue in infraorbital region, paranasal area, on the mouth next district, nasal area and superior labial region became protruding. There was no difference in soft tissue changes in the same facial area on the left and right sides, and gender had no effect on the changes of soft tissue in each area of the face after surgery.
