Introducrtion: Snoring is the noise produced by the vibration of the pharynx structures, which may be associated to Obstructive Sleep Apnea-Hipopnea Syndrome (OSAHS). Snoring affects 5 to 50% of the general population and OSAHS, 2 to 4%. Objective: To stress the importance of a comprehensive clinical and laboratory evaluation in the indications of both LAUP and somnoplasty as treatment alternatives for sleep-disorders. Material and method: Fifty subjects treated with LAUP, palate somnoplasty or both were included. The mean age was 42 years and 94% were male. Clinical evaluation included medical history, Epworth sleepiness scale, physical exam and ENT examination. A nasofibroscopy with Muller maneuver, in-hospital sleep studies and cephalometry were also performed. Results: Thirty nine patients (78%) reported just snoring and 11 patients (22%) reported snoring and apneas. The mean Epworth scale index was 7,3 points for the snoring group and 16 points for the snoring and apnea group. Sleep studies sorted out 32 patients (64%) with primary snoring, 8 (16%) had a mild OSAHS, 5 (10%) moderate OSAHS and 5 (10%) severe OHSAHS. LAUP was performed in 22 cases, somnoplasty in 6 and both in 22 patients. Conclusions: Individual evaluation of patients with snoring and respiratory pauses is of utmost importance for the treatment outcome. LAUP and somnosplasty offer good results when correctly indicated.
