In this study, we performed a case-control analysis of patients with and without epiglottic collapse. The clinical characteristics and adequate treatment methods of the patients with epiglottic collapse were identified. The study results showed that the Epi group had a similar degree of symptoms as the non-Epi group. However, the Epi group had relatively low BMIs and less severe OSA. Judging from the results of the DISE with multiple maneuvers, an oral device or positional sleep would be effective for epiglottic collapse.
