The average age was 54.7 years (SD 15.2), mean BMI was 28.6\u2009kg\/m<jats:sup>2<\/jats:sup> (SD 4.1), and mean apnea\u2010hypopnea 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, <jats:italic>P<\/jats:italic>\u2009=\u2009.008). 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\u20101.868], <jats:italic>P<\/jats:italic>\u2009=\u2009.048) 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\u20100.392], <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study demonstrates that a lower proportion of females have complete oropharyngeal lateral wall collapse even when controlling for BMI and AHI.
