title: Lingua-epiglottis position predicts glossopharyngeal obstruction in patients with obstructive sleep apnea hypopnea syndrome.
abstract: 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.
