摘　　要：目的:探讨多层螺旋CT气道三维重建评价阻塞性睡眠呼吸暂停综合征(OSAS)。材料和方法:对33例OSAS患者及66例正常人行多层螺旋CT气道三维重建,测量上气道的矢状径、冠状径及截面积。对比OSAS患者与正常人各径线的差异。结果:OSAS患者上气道最狭窄处最多见于软腭后区,矢状径、冠状径和截面积分别为8.96mm、16.64mm和164.62mm2;其次是悬雍垂区。与对照组相比,软颚后区及悬壅垂区的矢状径、冠状径及截面积明显较对照组小,且差异有统计学意义。结论:多层螺旋CT气道三维重建能够对气道进行精确测量,并对狭窄部位和范围进行定位,为选择治疗方案包括外科手术方式提供可靠依据。Purpose： To investigate the application of MSCT airway reconstruction in the patients with OSAS. Materials and Methods： MSCT and airway reconstruction were performed on 33 patients with OSAS and 66 normal persons. The sagittal diameter, coronal diameter and the section area of upper air way were measured. Results： The narrowest place of the air way was in the palate region. The sagittal diameter, coronal diameter and the section area was 8.96 mm, 16.64mm and 164.62 mm^2 respectively. Conclusion： With MSCT airway reconstruction, precision measurement of air way can be gotten. And can provide reliable evidence for clinic.
