How surgery for obstructive sleep apnea affects swallowing and oral function
Official title: The Effects of Surgery on Improving Oral Frailty and Dysphagia in Patients With Obstructive Sleep Apnea (OSA): A Prospective Cohort Study
Run by National Sun Yat-sen University · NCT07880067 · Data updated 2026-11-12
This study compares swallowing and oral function before and after surgical treatment for OSA versus non-surgical care in adults with moderate-to-severe OSA.

Is this trial a fit for you?
✓Likely a good fit
Adults 20 years or older with moderate-to-severe OSA (AHI ≥ 15) who plan to pursue next-step treatment and consent to participate.
✕Probably not a fit
Patients who do not experience changes in swallowing or oral function after treatment or whose baseline risk factors minimize potential benefits may see no improvement.

What this trial studies
This prospective observational cohort follows adults with moderate-to-severe obstructive sleep apnea who choose their next-step treatment at a sleep clinic in Taiwan. Participants are grouped by treatment choice—surgery or non-surgical care such as CPAP—and are assessed for swallowing difficulty and oral frailty at baseline, 1, 3, and 6 months after treatment. The study aims to understand how upper-airway surgery for OSA may impact swallowing function and oral health, including seven indicators of oral hypofunction. It is the second phase of a two-phase project, with Phase 1 examining retrospective health data to compare dysphagia incidence between OSA and non-OSA controls.
Why it matters
Potential benefit: If successful, findings could clarify risks or benefits of OSA surgery on swallowing and oral health, informing patient choices.
How similar studies have gone: Previous observational work has linked OSA and dysphagia; this study adds prospective data on surgical outcomes, which is relatively novel in this specific context.
