title: 15-year efficacy of uvulopalatopharyngoplasty based on objective and subjective data.
abstract: 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 (ODI(4) 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.
  
  
  OBJECTIVE
  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 ODI(4) was 26.5 (4-82).
  
  
  RESULTS
  In all, 13 patients had died; 26 patients underwent sleep apnoea recordings. Median ODI(4) 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.
