The PREDICTOR Study: Assessing Diagnostic Predictors of Airway Collapse in Patients With Obstructive Sleep Apnea

Not Applicable
Recruiting
Conditions
Sleep Apnea, Obstructive
Registration Number
NCT05428839
Lead Sponsor
Inspire Medical Systems, Inc.
Brief Summary

This study is an exploratory, multicenter study of up to 300 subjects diagnosed with obstructive sleep apnea who are being evaluated for airway surgery. Subjects will undergo standard evaluation for airway surgery as part of standard of care. In addition to the standard airway assessment, a simple, non-invasive measurement of the width of the inside of each subjects mouth will be performed. This measurement takes 2-3 minutes to perform.

Detailed Description

The objective of the study is to determine whether pharyngeal width (inside of the mouth) is an appropriate measurement to predict absence of complete concentric collapse (CCC) at the soft palate
