Summary

Acoustic Pharyngometry (AP) is a method of measurement of Transversal Sectional Areas (TSA) and Volumes of oral cavity and pharynx, based on acoustic waves. The aim of this study is to describe changes on oropharynx dimensions caused by CPAP (Continuous Positive Air Pressure) in patients with severe Obstructive Sleep Apnea Syndrome when compared with patients with Primary Snore, using AP. The exam will be made during the use of CPAP, at various pressures. The investigators also intend to determine if pressure determined by Polysomnography in OSAS patients cause some type of different change in AP graphic.
