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。

Abstract:

Objective To assess short- and long-term changes in the upper airway, natural head position and hyoid bone position in skeletal Class Ⅲ patients after bimaxillary surgery. Methods In this retrospective study, the cone-beam computed tomography(CBCT) of skeletal Class Ⅲ patients 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 position and hyoid bone was analyzed. Results Thirty skeletal Class Ⅲ patients(13 men and 17 women) who underwent bimaxillary surgery 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 airway.
