[Analyzed the related factors of VOTE score for drug-induced sleep endoscopy in patients with obstructive sleep apnea].

To analyze the related factors of VOTE score for drug-induced endoscopy（DISE） in patients with obstructive sleep apnea （OSA）. Fifty-four OSA patients, diagnosed by polysomnograph, underwent surgical treatment from Nov 2014 to Dec 2016 in our hospital. All patients underwent drug induced sleep endoscope, and then the collapse of pharyngeal space was evaluated. We analyzed the related factors with VOTE score. The occlusion rates were significant statistical different in different spaces of 54 OSA patients undergoing DISE（=0.000, velum 98.15%, oropharynx 81.48%, tongue base 40.47%, and epiglottis 11.11% respectively）. The rateand of tongue base collapsing was related with Mallampatis（<0.05） and Friedman stage（<0.05）. The VOTE score was weakly related with Friedman stage（=0.297, <0.05）, medium related with BMI（=0.376, <0.05）, AHI（=0.312, <0.05） and lowest SpO2（=0.376, <0.01）. In the VOTE scoring system for DISE, the rate of collapse in tongue base was related with Mallampatis and Friedman stage. The VOTE score was medium related with BMI, AHI and Lowest SpO2, mild related with Friedman stage.
