Objective To analyze the rate of diagnosis of advantages and disadvantages between the ifber optic endoscopy and CT scanning technology used for patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Method 48 cases of OSAHS patients were included in the awake state and induce sleep state and the downstream ifber endoscopy spiral CT scans from January 2012 to December 2013 comparative analysis of two diagnostic methods operating time, operating costs, in line with the rate of positive airway physiology and anatomy of the school to get information about the situation of OSAHS patients. Result All patients were successfully completed ifber optic endoscopy and CT scanning technology, ifber optic endoscopy checkups costs and operating time of less than CT checkups (P < 0.05). PSG checkups with OSAHS positive as diagnostic criteria, lesion location:32 cases retropalatal, 20 cases of the epiglottis area, 12 cases of lingual region. CT checkups OSAHS patients after soft palate area, the epiglottis and tongue area in line with higher ifber endoscopy (P < 0.05). Conclusion CT checkups OSAHS positive rate is higher, we can get the upper airway anatomy more information, ifber optic endoscopy simple operation, low cost checkups, clinical checkups can select the appropriate method based on the actual situation of the patient.%目的：对比分析应用光纤内镜技术及CT扫描技术诊断阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的优缺点及符合率。方法选取本院2012年1月至2013年12月收治的48例经多导睡眠监测仪（PSG）确诊的OSAHS患者为研究对象，所有纳入对象分别于清醒状态下及诱导睡眠状态下行光纤内镜检查及螺旋CT扫描，对比分析两种诊断方法操作时间、操作费用、阳性符合率及其对OSAHS患者的上气道生理解剖结构学信息的获取情况。结果所有患者均顺利完成光纤内镜及CT扫描技术，光纤内镜诊查费用及操作时间均少于CT诊查（P＜0.05）。以PSG诊查作为OSAHS阳性诊断标准，病灶位置：软腭后区32例，会厌后区20例，舌后区12例。CT诊查OSAHS患者软腭后区、会厌后区及舌后区符合率均高于光纤内镜（P＜0.05）。结论 CT诊查OSAHS阳性率较高，可获取上气道较多的解剖学信息，光纤内镜技术操作简单，诊查费用较低，临床可根据患者实际情况选取合适的诊查方法。
