About

The investigators hypothesize that sub-mental ultrasonography measures are strongly correlated with the severity of Obstructive Sleep Apnea Syndrome and the related specific subjective scales.

Full description

Polysomnography (PSG) is the gold-standard diagnose tool for Obstructive Sleep Apnea (OSA). However, the availability of PSG is limited, particularly in developing and / or least developed countries. Sub-mental ultrasonography is stepped forward with its practical and cheap nature and its widespread use.

The investigators aimed to perform sub-mental ultrasonography to the patients who underwent to PSG by a blind-to-the-PSG-results radiologist and analyse the correlation between ultrasound measures, Apnea-Hypopnea Index (measured by Polysomnography) and subjective OSA scales.
