Purpose
Epiglottic collapse is a specific sleep-endoscopic finding that can prove challenging to treat in patients with obstructive sleep apnea (OSA). Its effect on mandibular advancement devices (MAD) remains largely unknown. Therefore, this study assessed whether or not epiglottic collapse affects treatment outcome with MAD.
Methods
Patients with diagnosed OSAD underwent drug-induced sleep endoscopy (DISE) and were treated with a titratable MAD. Two age- and gender-matched controls were selected for every subject with primary epiglottic collapse (i.e., complete closure without involvement of other upper airway structures). Treatment response was defined as a reduction in oxygen desaturation index (ODI) of ≥ 50% following MAD therapy.
Results
Of 101 patients who underwent DISE, twenty (20%) showed primary epiglottic collapse (mean [SD]: 17 men; age 49.8 [10.1]; body mass index 28.3 [2.9] kg/m2; apnea-hypopnea index 27.0 [16.9] events/h). There were no significant differences in baseline clinical characteristics between cases and controls. MAD therapy was equally effective in patients with and without epiglottic collapse (mean [SD]; ODI with MAD, 8.7 [7.7] events/h vs. 7.8 [7.5] events/h, P = .62; ΔODI, 53.3 [29.6]% vs. 50.6 [37.7]%, P = .82; responder status, 10/20 vs. 22/40, P = .79). Logistic regression analysis revealed no associations between epiglottic collapse and treatment outcome.
Conclusion
The presence of epiglottic collapse during DISE does not impair the effectiveness of MAD. Therefore, MAD therapy should be considered in patients with predominant epiglottic collapse.
