Official Title: Benefit of Pharyngeal and Oesophageal pH-impedance of Patients With High Suspicion of Laryngopharyngeal Reflux

Brief Summary:

Laryngopharyngeal reflux (LPR) is the retrograde movement of gastric contents into the larynx, pharynx and upper aerodigestive tract. The symptoms and manifestations are very changeable and non specific. Pharyngeal and Oesophageal pH-impedance may help to detect these reflux and to identify patients with abnormal LPR.

To compare and describe the results of pharyngeal and oesophageal pH-impedance of patients with high suspicion of laryngopharyngeal reflux, with the results of healthy patients.
