摘　　要：目的本研究旨在评估双颌手术后骨性Ⅲ类患者上气道、自然头位和舌骨位置的短期和长期变化。方法在这项回顾性研究中,对骨性Ⅲ类患者分别在手术前(T0)、手术后3个月(T1)和手术后2年(T2)拍摄锥形束CT(cone⁃beam computed tomography,CBCT)。创建三维图像以评估术后变化,并分析上气道、自然头位和舌骨之间的相关性。结果对30例接受双颌手术的骨性Ⅲ类患者(男13例和女17例)进行了评估,他们的平均年龄为21岁(17~30岁)。T1和T2后,腭咽段、舌咽段和总上气道的体积明显缩小。下颌骨位置的变化与上气道体积的变化之间存在明显的相关性(P<0.05)。NSL/OPT和NSL/CVT在T1和T2后增大。NSL/CVT的变化与腭咽段和舌咽段体积的变化呈正相关(P<0.05)。结论双颌手术可能导致上气道体积减小、颅颈角增大、舌骨向下和向后移动。颅颈角的变化可能会引起上气道的改变。Objective To assess short⁃and long⁃term changes in the upper airway,natural head position and hyoid bone position in skeletal ClassⅢpatients after bimaxillary surgery.Methods In this retrospective study,the cone⁃beam computed tomography(CBCT)of skeletal ClassⅢpatients was taken before surgery(T0),3 months after surgery(T1)and 2 years after surgery(T2).Three⁃dimensional images were created to assess postoperative changes and the correlation between the upper airway,natural head posi⁃tion and hyoid bone was analyzed.Results Thirty skeletal ClassⅢpatients(13 men and 17 women)who underwent bimaxillary sur⁃gery with a mean(SD)age of 21 years(a range of 17-30 years)were evaluated.A significant decrease was observed in the volume of palatopharynx,glossopharynx and total airway after T1 and T2.There was a significant correlation between changes in the position of the mandible and changes in the volume of the upper airway(P<0.05).The NSL/OPT angle and the NSL/CVT angle were greater after T1 and T2.The change in the NSL/CVT angle was positively correlated with the change in palatopharyngeal and glossopharyngeal volume(P<0.05).Conclusion Bimaxillary surgery may cause a decrease in upper airway volume,an increase in the cranio⁃cervical angle,and a downward and backward movement of the hyoid bone.Changes in the cranio⁃cervical angle may cause changes in the upper air⁃way.
