The degree of velum and tongue base obstruction was significantly associated with sleep apnea severity in positions 2, 3, and 4 after adjusting for age, BMI, tonsil size, and tongue position.
Understanding the specific obstructions can guide targeted treatments for sleep apnea.

- Patients with persistent complete concentric velopharyngeal collapse in the supine position had a mean apnea–hypopnea index (AHI) of 54.7 events/h, significantly higher than the 60 patients without such collapse in position 4, who had a mean AHI of 35.5 events/h.Strong
- The study demonstrated the feasibility, safety, and usefulness of using a simple edge‐to‐edge, reusable oral appliance in drug-induced sleep endoscopy.Strong
