Diagnostic Validation of Drug-Induced Sleep Endoscopy (DISE)

This study aims to validate whether the pattern of airway collapse recorded during Drug-Induced Sleep Endoscopy (DISE) mirrors that of natural sleep, and to develop a model for airway collapse. Sensors will be placed in subjects' upper airways during DISE and then during in-lab sleep studies. The sleep study results will be compared with OR findings to create an aerodynamic model for natural sleep and to assess whether airway observations during DISE were valid representations of natural sleep.
