The aim of the study is to find, using validated and efficient tools, a laryngopharyngeal reflux in patients receiving polysomnography for suspected obstructive sleep apnea syndrome.

It is proposed to carry out simultaneously, at the Sleep Center of the Polyclinique of Poitiers (CSPP), a polysomnography, a 24-hour Restech pharyngeal pH-metry (day and night), a Peptest (in the evening and in the morning of the polysomnography), with the RSS-12 questionnaire and the RSA score.
