[Laryngopharyngeal reflux]

Abstract

Laryngopharyngeal reflux (LPR) or reflux laryngitis refers to the backflow of stomach contents into the larynx and hypopharynx. LPR is increasingly cited as the cause of laryngeal signs and symptoms such as globus sensation, hoarseness, chronic cough, chronic throat clearing, and throat pain. The diagnosis of LPR is often based on the presenting symptoms and associated laryngeal signs. An empiric trial of double-dose proton pump inhibitors (PPIs) has been recommended as a first line therapy in patients with suspected LPR. However, recent systemic review has shown no benefit of PPIs over placebo in the treatment of LPR. Clearly, more well designed, prospective large scale trials are warranted in the future.
