BACKGROUND: Heavy snoring and the obstructive sleep apnea syndrome are associated with increased morbidity and mortality in patients with cardiovascular disease. The effect of uvulopalatopharyngoplasty on mortality has been questioned.
OBJECTIVE: To investigate long-term survival after palatal surgery.
DESIGN: An observational retrospective case-control study with a 5- to 9-year follow-up.
SETTING: A university medical center.
PATIENTS: Four hundred consecutive heavy snorers (median age, 47 years), 256 of whom had obstructive sleep apnea syndrome. The mean +/- SD body mass index (calculated as weight in kilograms divided by the square of height in meters) of all included patients was 27.1+/-4.2. Comparison was made with 744 control patients (median age, 43 years) who underwent nasal surgery during the same period and a matched general control population.
INTERVENTION: Uvulopalatopharyngoplasty or laser uvulopalatoplasty between 1986 and 1990.
MAIN OUTCOME MEASURES: Mortality and causes of death up to 9 years after surgery.
RESULTS: High blood pressure at the time of surgery and subsequent death due to cardiovascular disease were 3 times more frequent in the patients with obstructive sleep apnea syndrome than in both control groups (P<.01), but the overall long-term mortality was not increased either in snorers or in persons with sleep apnea. The cumulative survival rate was more than 96% for the 400 patients, the 744 controls, and the matched general population.
CONCLUSIONS: No increased mortality was seen following palatal surgery in this long-term follow-up of 400 consecutive, on average, nonobese snorers, 256 of whom had obstructive sleep apnea syndrome. This might indicate a positive survival effect of surgery.
