摘要/Abstract

摘要： 目的：研究下颌升支矢状劈开前移术对成年骨性Ⅱ类下颌后缩女性患者上气道影响。方法：选取成年骨性Ⅱ类下颌后缩女性患者40例，根据采用不同的治疗方式分为两组：手术组20例采用双侧下颌升支矢状劈开截骨术前移下颌+正畸治疗，代偿组20例采用单纯正畸掩饰治疗。收集患者正畸治疗前和正畸治疗结束时的CBCT数据。分别测量正畸治疗前和正畸治疗结束时气道体积、截面积、矢状径，采用SPSS 25.0统计软件处理数据，自身对照配对t检验分析治疗前后变化。结果：代偿组所有测量项目差异均无统计学意义，手术组治疗后气道总体积、最小截面积和下界截面积显著增大。结论：对于成年骨性Ⅱ类下颌后缩女性患者，双侧下颌升支矢状劈开截骨术前移下颌可以增加气道体积和最小截面积，改善呼吸功能。单纯正畸掩饰治疗对成年女性骨性Ⅱ类下颌后缩患者气道无显著影响。

Abstract: Objective：Study on changes of airway before and after mandibular advancement orthoganic treatment in skeletal Ⅱ adult female. Methods：Forty skeletal Ⅱ adult female patients were divided into 2 groups: orthognathic group (20 patients) and orthodontic group (20 patients). CBCT was taken before and after treatment. The airway volume and cross-sectional area were measured before and after orthodontic treatment. SPSS 25.0 was used for analyzing the changes by t test. Results：After treatment, all the measurements in the orthodontic group were not significantly changed, while the total airway volume, the minimal cross sectional area and lower cross sectional area were significantly increased in orthognathic group. Conclusions：Mandibular advancement by sagittal splint ramus osteotomy can significantly increase the airway volume, minimal cross-sectional area and lower cross sectional area in skeletal Ⅱ adult female, improve respiratory function, while orthodontic treatmenthas no significant effect on airway in these skeletal Ⅱ adult female.
