Abstract: OBJECTIVE: To identify and characterize sex differences in collapse patterns on drug-induced sleep endoscopy (DISE) in patients with obstructive sleep apnea (OSA). STUDY DESIGN: Retrospective cohort analysis. SETTING: An outpatient tertiary care academic medical center. METHODS: A retrospective cohort study at a single tertiary care institution was performed from 2020 to 2023. All adult patients who underwent a DISE were included in this study. Univariate and multivariate analyses were used to compare differences between males and females on DISE. RESULTS: (SD 4.1), and mean apnea-hypopnea index (AHI) was 32.3 events per hour (SD 21.3). Most patients had severe OSA (48.7%). There was no difference in palatine or lingual tonsil size between sexes. On DISE, a significantly lower proportion of females demonstrated complete oropharyngeal lateral wall collapse (25.7% females vs 51.2% males, P = .008). Multivariate analysis revealed that male sex was independently associated with the presence of complete collapse at the oropharynx (odds ratio [OR] 2.55, 95% confidence interval [CI] [0.005-1.868], P = .048) but not at other levels. Additionally, higher BMI was associated with any collapse (partial or complete) at the oropharynx (OR 1.30, 95% CI [0.131-0.392], P < .001). CONCLUSION: This study demonstrates that a lower proportion of females have complete oropharyngeal lateral wall collapse even when controlling for BMI and AHI. Additional studies are needed to better understand the differences in OSA physiology between the sexes.
