Abstract：
OBJECTIVE: To assess the prevalence of arytenoid cartilage collapse (ACC) during deep inhalation in awake patients with intermediate/high risk of obstructive sleep apnea (OSA).
METHODS: Retrospective case-control study.
METHODS: The medical records and video recordings of awake flexible endoscopic examination of patients with history of OSA who presented to the sleep apnea clinic in a tertiary referral medical center between June 2022 and December 2022, were reviewed. All patients had filled the STOP-BANG questionnaire and had intermediate/high risk of having OSA. A group of patients matched by age and gender and with no history of OSA were used as controls.
RESULTS: A total of 95 patients, 64 with a history of OSA and 31 with no history of OSA, were included. Among the study group, 37.5% (n = 24) had a STOP-BANG score between 3 and 4 and were considered to be at an intermediate risk of OSA while the remaining had a score more than 5 and were considered to be at high risk of OSA. There was a significant difference in the prevalence of ACC between the study group and controls (32.8% vs 12.9%, respectively, P < 0.001).
CONCLUSIONS: The prevalence of ACC was significantly higher in patients with intermediate/high risk of OSA in comparison to healthy controls with no history of OSA. When present, ACC should raise the physician\'s suspicion for OSA and probably prompt further investigation such as a sleep study.

摘要：
目的：评估患有阻塞性睡眠呼吸暂停（OSA）的中/高风险清醒患者在深度吸入过程中的类软骨塌陷（ACC）的发生率。
方法：回顾性病例对照研究。
方法：回顾了2022年6月至2022年12月在三级转诊医疗中心就诊的有OSA病史的患者的清醒柔性内镜检查的病历和录像。所有患者都填写了STOP-BANG问卷，并且具有OSA的中/高风险。一组年龄和性别匹配且无OSA病史的患者用作对照。
结果：共有95名患者，64名患有OSA病史，31名没有OSA病史，包括在内。在研究小组中，37.5％（n=24）的STOP-BANG评分在3至4之间，被认为处于OSA的中等风险，而其余的评分超过5，被认为处于OSA的高风险。研究组和对照组之间ACC的患病率存在显着差异（32.8％vs12.9％，分别,P<0.001)。
结论：与无OSA病史的健康对照组相比，中/高风险OSA患者的ACC患病率明显更高。当存在时,ACC应该提高医生对OSA的怀疑，并可能促使进一步的调查，如睡眠研究。
