摘　　要：目的探究拔牙矫治对骨性Ⅰ类和骨性Ⅱ类双颌前突患者口咽部气道及舌骨位置的影响。方法回顾性纳入80例完成拔牙矫治(减数四个第一前磨牙)的骨性Ⅰ类和骨性Ⅱ类双颌前突成年患者,收集治疗前、后大视野CBCT影像,采用Dolphin软件测量口咽部气道及舌骨位置变化。结果骨性Ⅰ类患者拔牙矫治后口咽部气道形态发生显著变化,前后径缩窄,横径增宽,口咽部气道体积无显著变化,最小横截面积轻度减小,舌骨轻度向后移位。骨性Ⅱ类患者拔牙矫治后口咽部气道体积和最小横截面积出现轻度下降。骨性Ⅰ类患者和骨性Ⅱ类患者拔牙矫治口咽部气道和舌骨位置的变化无显著性差异。结论正畸拔牙矫治并不会造成骨性Ⅰ类和骨性Ⅱ类双颌前突患者医源性的气道狭窄。Objective To explore the effect of orthodontic extraction treatment on oropharynx and hyoid bone of skeletal ClassⅠand ClassⅡadult patients with bimaxillary protrusion.Methods A total of 80 adult patients with bimaxillary protrusion(40 skeletal ClassⅠpatients and 40 skeletal ClassⅡpatients)who underwent extraction of four premolars were included in this study.The pretreatment and posttreatment Cone-beam computed tomography were collected to measure oropharynx and hyoid bone changes using Dolphin 3DⅠmaging software.Results For skeletal ClassⅠpatients,the morphology of oropharynx changed after orthodontic extraction treatment,of which the anterior-posterior diameter decreased and the lateral diameter increased.The oropharynx volume remained stable,and the most constricted axial area of the oropharynx was slightly decreased.The hyoid bone moved posteriorly.For skeletal ClassⅡpatients,the volume and the most constricted axial area of oropharynx showed slight decrease,but without significant difference.The difference of oropharynx and hyoid bone changes was not significant between skeletal ClassⅠand skeletal ClassⅡpatients.Conclusion For skeletal ClassⅠand ClassⅡpatients with bimaxillary protrusion,orthodontic extraction treatment does not negatively influence oropharynx airway.
