15-year efficacy of uvulopalatopharyngoplasty based on objective and subjective data

Conclusions: This follow-up showed a stable and significant decrease in median oxygen desaturation index 4% (ODI(4)) values over the years. Approximately two-thirds of the patients fulfilled the success criteria (ODI4 reduction of 50% and <20) after 15 years. A majority had improved/cured excessive daytime sleepiness (EDS) and were satisfied. No increased mortality rate was seen. Objectives: To evaluate sleep apnoea recordings and symptoms in patients with obstructive sleep apnoea syndrome 15 years after uvulopalatopharyngoplasty (UPPP) compared to baseline and previous follow-ups. Methods: This was a non-randomized, prospective intervention study on 50 patients who underwent UPPP during 1985-88. Their initial median age was 49 years (range 38-71) and ODI4 was 26.5 (4-82). Results: In all, 13 patients had died; 26 patients underwent sleep apnoea recordings. Median ODI4 had decreased from 26.5 (range 4-82) to 8.5 (0-60), p < 0.01, a mean reduction of 52%; 65% of patients achieved the success criteria. One-third was objectively categorized as non-snorers. Median body mass index was unchanged. The questionnaires were answered by 32 of 37 patients; 88% reported improved or cured EDS and 78% were satisfied. Pharyngeal disturbances ratings were low. The standardized mortality rate did not differ from the general Swedish population.
