[The uvulopalatopharyngoplasty operation for obstructive sleep apnea syndrome]
Abstract:
We performed uvulopalatopharyngoplasty operations on 216 patients and conducted 6-month to 2-year follow-ups. 40 patients have had polysomnograms before and after operations. The clinical results showed 50 percent markedly improved, 28 percent somewhat improved, and 22 percent unimproved. The total success rate was 78%. The surgical procedures and polysomnogram methods have been introduced, and the pathogenesis, diagnostic criteria and results were discussed.
