Is this trial a fit for you?

Likely a good fit

Ideal candidates are adult patients with obstructive sleep apnea who are considering surgical treatment.

Probably not a fit

Patients who are minors, pregnant, or have contraindications to propofol will not benefit from this study.

What this trial studies

This study investigates the use of drug-induced sleep endoscopy (DISE) to assess the upper airway in patients with obstructive sleep apnea (OSA) who are considering surgical treatment. It aims to evaluate the reliability of DISE and compare its findings with traditional imaging techniques like lateral cephalogram X-ray. The study also focuses on patients who have not responded to previous sleep apnea surgeries, examining the correlation between DISE findings and surgical outcomes. The intervention involves sedation with propofol to facilitate the endoscopic evaluation.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate assessments of airway obstruction in OSA patients, improving surgical outcomes.

How similar studies have gone: Previous studies have shown moderate to substantial reliability of DISE, indicating potential for success in this approach.
