Drug-induced sleep endoscopy (DISE) is a safe and reliable technique for determining the pattern of upper-airway obstruction and the contribution of specific structures to airway obstruction. [55]

Identifying the site and the dynamic pattern of obstruction is mandatory in therapeutic decision-making, especially if a surgical therapeutic option is being considered. [56]

The nose-oropharynx-hypopharynx-larynx (NOHL) classification, which could be applied during awake and sleep endoscopy, allows a simple, quick, and effective evaluation of grade and patterns of upper-airway collapse. [57]
