%X <B>OBJECTIVE: </B>To assess the prevalence of arytenoid cartilage collapse (ACC) during deep inhalation in awake patients with intermediate/high risk of obstructive sleep apnea (OSA).<BR><B>METHODS: </B>Retrospective case-control study.<BR><B>METHODS: </B>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.<BR><B>RESULTS: </B>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).<BR><B>CONCLUSIONS: </B>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.
