目的:比较纤维喉镜与模拟内镜技术在阻塞性睡眠呼吸暂停低通气综合征(OSAHS)诊断中的作用和各自的优缺点;进一步探讨上呼吸道在阻塞通气过程中的变化特点。方法:我们对21例经睡眠监测确诊为OSAHS的患者行电子纤维喉镜检查,并行螺旋CT扫描后经软件处理,获得仿真上呼吸道图像。检查在清醒和睡眠2种状态下进行。测量软腭平面、悬雍垂平面、舌后平面和会厌平面的前后径和左右径。结果:纤维喉镜与仿真上呼吸道图像在上呼吸道的4个平面的测量上均差异有统计学意义;在清醒和睡眠状态下,软腭后区前后径的变化差异无统计学意义,其左右径差异有统计学意义。结论:清醒与睡眠状态下,上呼吸道的腔径有明显不同;腔径的变化以左右径变化为主;纤维喉镜在上呼吸道的动态观察中有很重要的诊断价值;仿真上呼吸道图像能够真实的显示上呼吸道狭窄的部位和程度;结合原始的二维图像可提供解剖结构和病理变化的相关信息。
OBJECTIVE: To compare the role of fibrolaryngoscope and simulated endoscopy in the diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS) and their respective advantages and disadvantages; and to further explore the characteristics of the upper airway during obstructive ventilation. METHODS: Twenty-one patients with OSAHS diagnosed by sleep monitoring underwent electronic fiber laryngoscopy. The CT scan was performed and software was processed to obtain simulated upper respiratory tract images. Check in awake and sleep 2 kinds of state. Measure the soft palate plane, uvula plane, posterior lingual plane and the epiphysis plane anteroposterior diameter and left and right diameter. Results: There were significant differences in the measurement of the upper respiratory tract between the laryngoscope and the simulated upper respiratory tract in four planes. In the awake and sleeping states, there was no significant difference in the anteroposterior diameter between the soft palate and the left and right The difference was statistically significant. CONCLUSIONS: In the awake and sleep states, the diameters of the upper respiratory tract are obviously different. The changes of the diameter of the upper and lower respiratory tract are mainly the changes of the left and right diameter. The fiber laryngoscope has important diagnostic value in the dynamic observation of the upper respiratory tract. Realistically shows the location and extent of upper airway stenosis; the combination of the original two-dimensional image provides information about anatomical and pathological changes.
