摘　　要：目的 :探讨骨性安氏Ⅱ类错患者采用外科—正畸联合治疗后颜面软组织侧貌在矢状和垂直方向上的变化。方法 :选用华西医科大学口腔医院正畸科连续收治的骨性安氏Ⅱ类错患者 2 2例 ,男 7例 ,女 15例 ,年龄 2 0～30岁。在术前及术后 6～ 12个月摄取X线头侧位片 ,对 16个软硬组织标志点的变化进行矢状、垂直向的分析。结果 :在矢状向上 ,上唇沟点、上唇缘点、上唇下点后退均大于 2mm(P <0 0 1) ;与上切牙点后移量之比为 0 5 9∶1～0 6 4∶1;颏唇沟软、硬组织点前移量之比为 0 83∶1,软组织颏前点与硬组织颏前点前移量之比为 0 95∶1。在垂直向上 ,鼻尖点、鼻底点、上唇缘点平均向上移动量均小于 1mm(P >0 0 5 ) ;但软组织颏前点、颏唇沟、下唇缘点、下唇上点向上移动量均大于 2mm(P <0 0 5 ) ,与相应的硬组织移动量之比为 1 0 7∶1～ 1 34∶1。结论 :骨性安氏Ⅱ类错患者经外科—正畸联合治疗后颜面软组织侧貌改善明显。在矢状方向 ,上下颌软组织改变量均小于硬组织 ;但在垂直方向 。Objective:One of the prime concerns of both the orthodontist and the oral surgeon must be the final soft tissue profile and the esthetic appearance of the patient. The purpose of this study was to evaluate the amount, direction, and predictability of the soft tissue changes associated with simultaneous skeletal changes.Methods:The authors analyzed the recent 22 cases with skeletal class II malocclusion in Orthodontic Department, College of Stomatology, West China University of Medical Sciences with 7 male and 15 female from 20 to 30 years old. Each patient was taken standardized lateral cephalograms before the treatment and 6～12 months after the treatment. A total of 16 hard and soft tissue landmarks were evaluated in both horizontal and vertical directions.Results:In the horizontal directions, the soft tissue maxillary landmarks (superior labial sulcus, labrale superius, and upper lip stomion) moved posterior with a range of 2.17 to 2.33 mm. The strongest correlations were found between the posterior movement of the upper incisal edge and the three soft tissue parameters: superior labial sulcus r=0.78, labrale superius r=0.81, upper lip stomion r=0.75. The soft/hard tissue ratios of the mandible anterior movement is 0.83∶1 between inferior labial sulcus and B point, and 0.95∶1 for Pog′ to Pog. In the vertical directions, all the soft tissue mandible landmarks (Pog′, inferior labial sulcus, labrale inferius, lower lip stomion) moved upward more than 2 mm. And the soft/hard tissue ratio is from 1.07∶1 to 1.34∶1.Conclusion:The combined orthodontic and surgical treatment is an efficient way to cure skeletal class II malocclusion. All the patients regained satisfactory face appearance and profile. Although the soft tissue movement is less than the hard tissue in both jaws in the horizontal direction, the vertical movement of the mandibular soft tissue is greater than that of the underlying hard tissue.
