Epiglottis-related obstruction occurred in 103 (16%), including 100 (14%) and 13 (1.8%) with anteroposterior and lateral configurations, respectively. Multivariable analysis showed that anteroposterior epiglottis-related obstruction was strongly associated with male sex (odds ratio [OR], 2.84; 95% CI, 1.20-6.73), lesser degree of velum-related obstruction (OR, 0.50; 95% CI, 0.29-0.84), and posterior epiglottis displacement (OR, 2.94; 95% CI, 1.73-4.99), and weakly associated with older age (OR, 1.04; 95% CI, 1.01-1.06). Lateral epiglottis-related obstruction was only seen in male individuals and the presence of oropharyngeal lateral-wall related obstruction; it was also associated with posterior epiglottis displacement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-ooi250041-10\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>This study found that anteroposterior and lateral epiglottis-related obstruction are distinct, having many different risk factors.
