Long-term follow-up of patients operated with Uvulopalatopharyngoplasty from 1985 to 1991

Abstract

Short-term outcome and side effects after Uvulopalatopharyngoplasty (UPPP) are well recognized. However, there is a lack of knowledge of the long-term outcome and side effects after this surgery. This study was completed to investigate the outcome and side effects 20 years after UPPP for snoring and obstructive sleep apnoea. Medical records of patients who underwent UPPP surgery for sleep apnoea and snoring between 1985 and 1991 were investigated retrospectively. A specific questionnaire focusing on the present health profile, side effects of previous UPPP surgery and present sleeping patterns of patients was mailed out. UPPP patients, 186 (including 11 females) were identified. Of these, 35 (19%) had passed away and 7 (4%) were not located. 129 patients (mean: age 68 years, range 43-83) of the possible 144 patients answered the questionnaire (response rate 90%). At follow-up, 41 patients (32%) used continuous positive airway pressure (CPAP). 66 of the patients (52%) were satisfied with the result of the operation, but 61 (47%) were not satisfied. 49 patients (38%) reported persistent side effects (problems with nasal regurgitation 18 (14%), swallowing 26 (20%), changed voice 15 (12%), and pain in the oral cavity 15 (12%). Almost 50% of patients operated with UPPP were not satisfied with the result of the operation after about 20 years, and one third used CPAP at follow-up. A large proportion of patients still experienced side effects, which, after this time, are likely to be permanent.
