摘要
目的:利用64层螺旋CT观察阻塞性睡眠呼吸暂停综合征(OSAHS)患者上气道大小形态改变,探讨其在指导临床诊治工作中的应用价值。方法:对38例OSAHS患者及20例健康成人行上气道64层螺旋CT扫描,分别测量2组患者软腭长度、悬壅垂长度、咽侧距、腭咽距及腭咽腔最小截面积并进行统计学分析。结果:OSAHS患者软腭长度[(29.11±3.78)mm]较健康对照组[(23.40±2.55)mm]增大,而咽侧距、腭咽距及腭咽腔最小截面积[分别为(22.35±3.59)mm、(12.84±1.94)mm和(175.50±24.43)mm2]较健康对照组[分别为(10.23±4.17)mm、(9.72±2.04)mm和(52.61±3.13)mm2]减小,差异均具有显著性意义(P<0.05)。结论:64层CT上气道扫描并进行定量分析可协助临床判断OSAHS患者上气道阻塞部位及程度,为临床治疗提供准确的解剖学依据。
Objective： To explore the morphological changes of upper respiratory tract in patients with obstructive sleep apnea hypopnea syndrome （OSAHS） by using 64-slice spiral CT. Methods：Thirty-eight patients with OSAHS and 20 controls were scanned by 64-slice spiral CT. The lengths of soft palate and uvula, distance of pharynx and palatopharynx, and the minimum section of glossopharynx were measured. Results：The lengths of soft palate and the uvula were larger in OSAHS group than in the normal control group. Distance of pharynx and palatopharynx,and the minimum section of glossopharynx were less in OSAHS group than in the normal control group. The difference between the two groups was significant （independent t test,P〈0.05）. Conclusion： Measurements of upper airway morphology with 64-slice spiral CT are important in investigating the anatomic changes of of OSAHS.
