Drug-Induced Sleep Endoscopy Findings in Supine vs Nonsupine Body Positions in Positional and Nonpositional Obstructive Sleep Apnea.

ABSTRACT:

Importance

The anatomic mechanisms underlying positional vs nonpositional obstructive sleep apnea (OSA) are poorly understood and may inform treatment decisions.

Objective

To examine drug-induced sleep endoscopy (DISE) findings in the supine vs nonsupine body positions in positional and nonpositional obstructive sleep apnea.

Design, setting, and participants

A cross-sectional study of 65 consecutive eligible adults with OSA undergoing DISE without marked tonsillar hypertrophy, including 39 with positional OSA (POSA) and 26 with nonpositional OSA (N-POSA) was conducted in a sleep surgery practice at a tertiary academic medical center.

Exposures

Drug-induced sleep endoscopy performed in the supine vs nonsupine body position.

Main outcomes and measures
