Long-term evaluation of satisfaction and side effects after modified uvulopalatopharyngoplasty.

OBJECTIVES/HYPOTHESIS: We have previously shown that modified uvulopalatopharyngoplasty (UPPP) is effective to treat obstructive sleep apnea (OSA) and that the effect is stable after 24 months. This continuous report includes questionnaires and phone interviews. STUDY DESIGN: Prospective intervention study. METHODS: Sixty-five patients with apnea-hypopnea index (AHI) score ≥ 15, body mass index <36 kg/m2 , and Epworth Sleepiness Scale (ESS) score ≥ 8 underwent modified UPPP after failing nonsurgical treatment. The results from a patient questionnaire at 6 and 24 months after surgery were correlated with age, body mass index, and ESS and AHI scores. Patients reporting side effects and/or regretting the surgery after 24 months were selected for phone interviews 9 years after surgery. RESULTS: The response rate was 80% and 74% at the 6- and 24-month follow-ups, respectively. Of those who responded to the questionnaire, 96% and 83% were satisfied after 6 and 24 months, respectively; 98% and 92% recommended the surgery. Side effects (globus, mucus, and voice and swallowing disorders) occurred in 38% and 31%, respectively. Dissatisfaction correlated significantly with high postoperative AHI and ESS scores, but not with occurrence of side effects. Younger subjects had a higher rate of recommendation and lower rate of side effects than did older subjects. Phone interviews after 9 years were responded to by 14 of 16 selected patients, and the responders reported minor or no side effects. CONCLUSIONS: The vast majority of the OSA patients were satisfied 24 months after surgery, even though a third of them were experiencing side effects. Younger patients had fewer side effects than did older patients. Patients with better OSA outcomes were also more satisfied. After 9 years the side effects were no longer problematic.
