Excessive daytime sleepiness and fatigue in nonapnoeic snorers: improvement after UPPP

Even in the absence of sleep apnoea, heavy snoring may be a cause of excessive daytime sleepiness (EDS) and fatigue. The aim of this investigation was to study whether uvulopalatopharyngoplasty (UPPP) is effective in relieving snoring and excessive daytime sleepiness in nonapnoeic snoring patients. UPPP was assessed in 155 nonapnoeic, snoring patients (136 men and 19 women, mean age 45 yrs). Postoperative evaluation was made after 3 months in 105 patients, and after 12 months in 50 patients. Fifty four patients were evaluated after both 3 and 12 months. In 49 patients, a further evaluation was made after 2 yrs. The results were compared with those of 76 conservatively-treated, nonapnoeic, snoring patients, who were reinvestigated 12 months after their initial examination. The proportion of patients with frequent loud snoring had decreased postoperatively from 96 to 18%. A highly significant improvement was reported in EDS and daytime fatigue. The proportion of patients who reported problems staying awake when driving had decreased from 29 to 7%, and the number who felt rested when awakening in the morning had increased from 23 to 78 after the operation. The patients in the UPPP group had somewhat more severe symptoms before treatment than those treated conservatively. One year after treatment the situation had been reversed, with significantly more snoring and excessive daytime sleepiness in the conservatively-treated group. In conclusion, these results indicate that UPPP is effective in relieving snoring and EDS in nonapnoeic snorers.
