Assessment of uvulopalatopharyngoplasty for the treatment of sleep apnea syndrome.
Uvulopalatopharyngoplasty (UPPP) consists in the surgical removal of the uvula, part of the muscular portion of the soft palate and redundant palatal and pillar mucosa, and the tonsils. Since 1981, UPPP has been proposed for the treatment of sleep apnea syndrome. Polysomnographic studies have shown that in about half of the patients submitted to UPPP there is a 50% or greater reduction in apnea index. Attempts to identify presurgically those patients more likely to benefit from UPPP have yielded inconsistent results. Limited retrospective follow-up data suggest that UPPP does not modify the increased mortality associated with moderate and severe sleep apnea syndrome. Patients submitted to UPPP report subjective improvement, irrespective of the objective polysomnographic postsurgical results. It is suggested that polysomnographic evaluation of UPPP results should be mandatory; that any patient with 20 or more apnea/hypopneas per hour of sleep or sleep fragmentation after UPPP should be considered a treatment failure and be offered alternative therapy; and that UPPP should be performed only as part of prospective clinical trials including long-term follow-up.
