Eight-Year Follow-up of Modified Uvulopalatopharyngoplasty in Patients With Obstructive Sleep Apnea

• Objective To investigate whether modified uvulopalatopharyngoplasty (UPPP) for treatment of obstructive sleep apnea (OSA) remained effective after 8 years. Methods Prospective intervention study. Sixty-five patients with OSA were offered re-evaluation with polysomnography and the Epworth Sleepiness Scale (ESS) 8 years after UPPP. Results were compared with baseline and with a previous 2-year follow-up. Baseline predictors were analyzed with regression analyses. Results The dropout rate at the 8-year follow-up was 28%. The mean decrease in apnea-hypopnea index (AHI) between baseline and the 8-year follow-up was significant, 14.0 events/hour (from 52.9 to 38.9), 27% (P < .001). The mean increase in AHI between the 2-year and the 8-year follow-up was significant, 14.7 events/hour (from 24.2 to 38.9), 61% (P < .0001). Overweight at baseline predicted an AHI at the 8-year follow-up that was 22.9 events higher compared to patients with normal weight (P= .015). An increase in body mass index (BMI) of 1 kg/m(2)between baseline and the 8-year follow-up predicted a mean AHI increase of 3.8 events/hour (P= .015). The median decrease in ESS between baseline and the 8-year follow-up was significant, 7 (from 13.0 to 6.0), 54% (P < .0001). The median increase in ESS between the 2-year and the 8-year follow-up was not significant, 1.0 (from 5.0 to 6.0), 20%. Conclusion Modified UPPP was effective as a long-term treatment for OSA in selected patients, although the effect on AHI decreased over time. Daytime sleepiness remained improved even in the long term. High BMI at baseline and an increase in BMI predicted a reduced long-term respiratory outcome. Level of Evidence 3Laryngoscope, 2020
