The objective of the study was to investigate the relationship between lingua-epiglottis position and glossopharyngeal obstruction in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). One hundred and four patients with OSAHS diagnosed by polysomnography (PSG) were enrolled. Lingua-epiglottis position was visualized using endoscopy and classified into three types. Spiral CT imaging of the upper respiratory tract was performed to measure the cross-sectional area and inner diameter of the glossopharyngeal airway. The PSG was repeated after nasopharyngeal tube insertion (NPT-PSG). The NPT-PSG results, CT-measured data and incidence of stenosis were compared among the different lingua-epiglottis position groups. Obstructive sleep apnea hypopnea syndrome patients with different lingua-epiglottis positions had similar demographics. As lingua-epiglottis position type varied from type I to type III, cross-sectional area and inner diameter of the glossopharyngeal area decreased, glossopharyngeal airway stenosis rate increased, and apnea hypopnea index measured by NPT-PSG increased. The lowest oxygen saturation decreased. Lingua-epiglottis position was significantly related to glossopharyngeal obstruction. Lingua-epiglottis position should be used in clinical practice for the preliminary assessment of glossopharyngeal obstruction.
本研究的目的是调查阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者的舌会厌位置与舌咽阻塞之间的关系。纳入了104例经多导睡眠图（PSG）诊断为OSAHS的患者。使用内窥镜观察舌会厌位置，并将其分为三种类型。对上呼吸道进行螺旋CT成像，以测量舌咽气道的横截面积和内径。在插入鼻咽管后重复进行PSG（NPT-PSG）。比较不同舌会厌位置组之间的NPT-PSG结果、CT测量数据和狭窄发生率。不同舌会厌位置的阻塞性睡眠呼吸暂停低通气综合征患者的人口统计学特征相似。随着舌会厌位置类型从I型变为III型，舌咽区域的横截面积和内径减小，舌咽气道狭窄率增加，NPT-PSG测量的呼吸暂停低通气指数增加。最低血氧饱和度降低。舌会厌位置与舌咽阻塞显著相关。舌会厌位置应用于临床实践中对舌咽阻塞的初步评估。
