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.
