| Abstract | Objective: To assess the prevalence of arytenoid cartilage collapse (ACC) during deep inhalation in patients with intermediate/ high risk of obstructive sleep apnea (OSA).
Methods/ Design : In a retrospective case-control study, the medical records and video recordings 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). ACC was slightly more prevalent in patients at high-risk of OSA in comparison to those in the intermediate-risk category (35% vs. 29.2%, respectively, p=0.630).
Conclusion: 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.
