Overview
Extraesophageal reflux refers to reflux of the (duodeno)gastric content that reaches structures superior to the level of the upper esophageal sphincter. It has been implicated in the pathogenesis of several otolaryngological disorders, including posterior laryngitis, vocal folds nodules, paroxysmal laryngospasm, Reinke’s edema, vocal fold ulcers and granuloma, globus pharyngeus, subglottic and laryngotracheal stenosis. Moreover, recent investigations indicate, that it can play a role in chronic rhinosinusitis, chronic ear complaints, snoring and laryngopharyngeal carcinoma. Because of nonexisting simple and effective diagnostic instrument, cause-and-effect relationship is far from proven. The review sumarizes this controversial topic emphasizing recent investigation results regarding pathogenesis and diagnostic procedures. In spite of the lack of consensus concerning interpetation criteria, 24hour pH-metry still remains the gold diagnostic tool.
