IMAGES: Drug-Induced Sleep Endoscopy: An Investigative Tool for Mechanisms of PAP Failure.

ABSTRACT:

Abstract

This is a case report of a 60-year-old female with mild obstructive sleep apnea (OSA) who presented to CPAP Alternatives clinic following multiple failed attempts at positive airway pressure (PAP) therapy. She underwent drug-induced sleep endoscopy (DISE) with the concurrent application of PAP via two different mask types. Application of the oronasal mask at low pressures demonstrated soft palate collapse, while high pressures resulted in posterior tongue collapse. In contrast, application of the nasal mask eliminated palatal and tongue obstruction at low pressures, despite mask leak at higher pressures. She was recommended a trial of nasal autoPAP, which with the use of a chinstrap, resulted in both subjective and objective improvement of her OSA.
