Purpose of Review

To review whether drug-induced sleep endoscopy (DISE) aids in obstructive sleep apnea surgical planning, if it changes the initial proposal, and if so, does it contribute to increased surgical success or unnecessary morbidity?

Recent Findings

A DISE and surgical outcomes multicenter cohort study (n = 275) reported no association for surgical outcomes with velopharyngeal and epiglottic collapse. Oropharyngeal and tongue base collapse on the other hand were associated with lower odds of surgical response.


DISE changes surgical planning mainly in regard to the approach of the tongue base and epiglottis, as these structures usually do not collapse in the awake state. The decision of velopharyngeal surgery usually does not change, as the vast majority demonstrate velopharyngeal collapse in DISE. Whether DISE increases or not, surgical success is controversial, with conflicting published data. However, poorer surgical outcomes have been associated with velopharyngeal concentric, oropharyngeal lateral wall, and tongue base collapse.
