Dual pH with Multichannel Intraluminal Impedance Testing in the Evaluation of Subjective Laryngopharyngeal Reflux Symptoms.

Abstract

Minimal data exist to define the use of contemporary dual pH with multichannel intraluminal impedance (MII) probes integrating both pharyngeal acid and impedance sensors to evaluate laryngopharyngeal reflux (LPR) symptoms in a laryngology clinic population. This study was performed to review a series of patients tested with dual pH-MII for suspected LPR symptoms and to analyze pH-MII data findings for this patient cohort.
