Abstract
Drug-induced sleep endoscopy (DISE) was developed for dynamic evaluation of the airway collapse under simulated sleep conditions. DISE has been extensively studied in the last 25 years to standardize the procedures and classification as well as its role in non-surgical and surgical management. The goal of this study is to determine current techniques and recommendations regarding DISE. Current research suggests that standardization with target-controlled infusion and bispectral analysis may be safer and more reproducible. The velum, oropharyngeal, tongue base, epiglottis classification remains the most commonly used to describe the obstruction. While DISE changes surgical management in 50% of patients, there are few studies to evaluate differences in surgical outcomes with and without DISE. Emerging evidence suggests complete collapse of the velum and hypopharyngeal obstruction are associated with poor surgical outcomes. Going forward, more information is required to determine how well DISE mimics natural sleep and its role in decision-making for patients seeking alternatives to continuous positive airway pressure.
