Evaluating the upper airway in obstructive sleep apnea using drug-induced sleep endoscopy

Drug-Induced Sleep Endoscopy for Upper Airway Evaluation in Obstructive Sleep Apnea

Phase 2 Interventional University of California, Los Angeles · NCT00695214

This study is testing if a special sleep test using medication can help doctors better understand the airways of people with obstructive sleep apnea who are thinking about surgery.

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.

Who should consider this trial

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

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

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