摘要
目的 了解CT测量在阻塞性睡眠呼吸暂停综合征(OSAS)上呼吸道狭窄定位诊断中的意义。方法OSAS病人59例为A组,上呼吸道阻塞部位者35例为B组,正常人53人为对照组,CF扫描并测量各平面呼吸道横截面积等参数。结果A组和对照组比较,4个平面左右径和悬雍垂区前后径明显小于对照组;软腭后区、悬雍垂区和舌后区横截面积明显小于对照组;4个测量平面咽侧壁软组织厚度、软腭后区和悬雍垂区的咽后壁软组织厚度明显大于对照组。B组与对照组比较,各测量指标差异更加明显,B组中超出各测量值正常范围的病人比率明显多于A组。结论 常规CF测量对OSAS病人上呼吸道阻塞部位的定位诊断具有较好的价值。
ve To explore the value of CT scan in diagnosing the upper airway stricture in patients with obstractivesleep apnea syndrome (OSAS). Methods Fifty-nine OSAS patients (group A), 35 OSAS patients with obstructive sites already known (group B), and 53 normal adults were included in the study. CT scan was used to measure and evaluate the area and the dimensions of the palate, uvula, lingua, and epiglottis region, and the thickness of retropharyngeal and lateral pharyngeal tissue. Results Compared with the control group, the left-and-right dimension of the four areas and the fore-and-aft dimension of don field of group A were obviously smaller; the areas of retro-soft palate, cion and retro-lingua were obviously smaller, while the thickness of pharyngo-kteral wall, retro-soft palate and cion tissue was significantly larger. Differences were even larger between group B and the controls. The abnormal rate in group B was higher than that of group A. Conclusion CT scan is helpful in measuring the upper airway obstructive sites in OSAS patients.
