RESUMEN
OBJECTIVES: The aim of the present study is to investigate the efficacy of the Velumount device. METHODS: In a prospective cohort study 40 patients were examined with and without Velumount. The apnea-hypopnea index and average esophageal pressure were measured using nocturnal manometry of the upper airways, combined with respiratory polygraphy. The snoring index (1-10) and daytime sleepiness using the Epworth Sleepiness Scale were assessed by means of a questionnaire. RESULTS: Using Velumount the snoring index was reduced from on average 8.4 (SD +/- 1.3) to 3.7 (SD +/- 2.5), the Epworth Sleepiness Scale score from on average 7.9 (SD +/- 4.4) to 3.8 (SD +/- 3.4) and esophageal pressure from on average 14.8 cm H(2)O (SD +/- 6.7) to 11.2 cm H(2)O (SD +/- 6.4). In patients (n = 25) with obstructive sleep apnea, the average apnea-hypopnea index was 24.3 (SD +/- 10.1) without and 13.6 (SD +/- 12.2) with Velumount. All changes were highly significant. CONCLUSIONS: The Velumount device is effective for the treatment of snoring and obstructive sleep apnea. The effect is similar to that reported from uvulopalatopharyngoplasty.
