【摘要】：阻塞性睡眠呼吸暂停综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)的发病主要是由于上气道解剖上的狭窄和呼吸控制功能失调而造成。OSAHS症状正确诊断对于OSAHS的有效治疗十分重要。上呼吸道CT对OSAHS患者上气道狭窄部位扫描定位是临床上的重要诊断手段,如何分析CT扫描数据,对于正确判断OSAHS具有意义。本研究以健康人群常规CT扫描数据确立了检测指标的正常范围,选用58例OSAHS患者进行上呼吸道CT。研究结果表明:58例患者中13例无明显狭窄,45例患者存在横截面狭窄,统计发现狭窄层面共71个。在45例OSAHS患者中,26例为单个层面狭窄,其中15例为软腭后区狭窄,2例为悬雍垂区狭窄,4例为舌后区狭窄,5例为会厌后区狭窄;在45例OSAHS患者中,16例患者存在两个层面的联合狭窄,一般为相邻部位,其中6例为软腭后区+悬雍垂区狭窄;6例悬雍垂区+舌后区狭窄,4例为舌后区+会厌后区狭窄;另外,CT扫描显示2例OSAHS患者的层面狭窄成3个部位的联合,分别为软腭后区+悬雍垂区+舌后区;而2例患者的层面狭窄为4个部位联合。进一步对15例清醒状态和睡眠呼吸暂停状态下的OSAHS患者进行的上呼吸道CT扫描对比发现,清醒状态下的上呼吸扫描提示的狭窄部位与睡眠呼吸暂停状态下发生的阻塞部位基本吻合。从本研究结果,我们认为大多数OSAHS患者存在上呼吸道的解剖性狭窄,且狭窄部位基本与睡眠呼吸暂停发生状态下阻塞部位相一致,进一步说明上呼吸道CT扫描对OSAHS患者阻塞及狭窄的定位具有重要临床诊断价值。
[Abstract]:Obstructive sleep apnea syndrome (obstructive sleep apnea hypopnea syndrome,OSAHS) is mainly caused by anatomic stenosis of upper airway and maladjustment of respiratory control. The correct diagnosis of OSAHS symptoms is very important for the effective treatment of OSAHS. Upper respiratory tract CT is an important diagnostic method for upper airway stenosis in patients with OSAHS. How to analyze CT scan data is of significance to correctly judge OSAHS. In this study, the normal range of detection indexes was established by routine CT scan data of healthy population. 58 patients with OSAHS were selected for upper respiratory CT.. The results showed that 13 of 58 patients had no significant stenosis and 45 had cross-sectional stenosis. A total of 71 stenosed layers were found. Of the 45 patients with OSAHS, 26 were single level stenosis, including 15 cases of posterior soft palate stenosis, 2 cases of uvula stenosis, 4 cases of retrolingual stenosis and 5 cases of posterior epiglottic stenosis. Of the 45 patients with OSAHS, 16 had two levels of conjunctival stenosis, 6 of which were associated with the posterior soft palate uvula, 6 of the retrolingual and 4 of the posterior epiglottis, 6 of the 45 patients with OSAHS had conjunctive stricture, 6 of them were located in the posterior soft palate, 6 had the retrolingual stricture and 4 had the posterior epiglottis. In addition, CT scan showed that the laminar stenosis of 2 patients with OSAHS was combined into three parts, the posterior region of the soft palate was the posterior part of uvula and tongue, while the plane stenosis of 2 cases was combined with four sites. Further CT scans of upper respiratory tract were performed in 15 patients with OSAHS in awake state and sleep apnea. The stricture of upper respiratory scan in waking state coincided with that in sleep apnea. From the results of this study, we believe that most OSAHS patients have anatomic stenosis of the upper respiratory tract, and the stenotic site is basically consistent with the obstructive site in the state of sleep apnea. It is further indicated that CT scan of upper respiratory tract has important clinical value in the diagnosis of obstruction and stenosis in patients with OSAHS.
