Laryngopharyngeal Reflux: Weak Acid and Weaker Correlations

Excerpt

Cough, sore throat, hoarseness, globus sensation, neck pain, or a burning sensation in the tongue or mouth may be a consequence of laryngopharyngeal reflux (LRP), but these symptoms are non-specific and can be due to conditions other than LPR such as sinusitis, postnasal drip, allergies, or underlying laryngeal pathology [1, 2]. Further, as the name implies, LPR is presumed to be related to reflux of gastric contents up to the larynx and pharynx. The challenge with LPR has been to objectively confirm the presence of the disease in those that have it and likewise exclude it in those with symptoms attributed to alternate etiologies. Currently, although there is no “gold standard” test for the diagnosis, objective testing options include impedance–pH monitoring, particularly with catheters that extend above the upper esophageal sphincter, dual-probe pH testing, and Restech^® pharyngeal pH monitoring. …
