摘　　要：目的:通过头颅定位侧位片分析骨性Ⅲ类错[牙合]患者行双侧下颌支矢状劈开后退术前后上气道变化。方法:就诊于2016年1月~2019年6月徐州市口腔医院25例骨性Ⅲ类错[牙合]患者,男性13例,女性12例,平均年龄22.15岁。术前后均拍摄头颅定位侧位片,术中双侧下颌行矢状劈开行完成后退。术后1周,1月,3月及6个月分别测量上气道矢状向间隙变化,包括鼻咽、软腭、舌根及会厌后区,并评估舌骨位置改变。结果:术后上气道三处解剖平面(软腭、舌根及会厌后区)均出现矢状向缩小;男性舌骨位置较女性向后下方移位明显。不同性别间之间上气道间隙变化无统计学差异。结论:骨性Ⅲ错颌畸形患者行下颌骨升支矢状劈开后退术后,上气道均出现不同程度的缩窄及舌骨下后方移位。下颌骨后退距离过大可能导致阻塞性睡眠呼吸障碍。Objective:To evaluate the change in pharyngeal airway space and the position of hyoid bone after mandibular setback in patients with skeletalⅢmalocclusion.Methods:25 patients with skeletalⅢmalocclusion were collected from Jan.2016 to Jun.2019 in Xuzhou Stomatological Hospital,in which male were 13 and female were 12.The mean age was 22.15.The bilateral sagittal split ramus osteotomy(BSSRO)was applied.Lateral cephalometric radiographs were taken before and after surgery.The changes of airway in soft palate,tongue,epiglottis region,and hyoid bone position were measured in sagittal direction.Results:After the operation,the soft palate,base of tongue,and posterior area of epiglottis were narrowed,and hyoid bone shifted backwards and downward in all patients.There was no significant statistical difference in upper airway between male and female,while hyoid bone position in males was lower than that in females.Conclusion:The study indicated that BSSRO made upper airway narrow in different degrees and hyoid bone shifting after operation.Obstructive sleep apnea-hypopnea syndrome would be caused by the great amount of mandibular setback.
