A New Nasopharyngeal pH Probe for Diagnosis of Laryngopharyngeal Reflux

Withdrawn before enrolling · Phase 4

Conditions studied: Laryngopharyngeal Reflux

In brief

The purpose of this study is to evaluate the utility of a minimally invasive nasopharyngeal pH probe for the diagnosis of laryngopharyngeal reflux (LPR) in children with airway compromise; to determine whether it is comparable to the gold standard esophageal pH probe in identifying LPR in this population; and to correlate results of pH testing with validated questionnaires. Our hypothesis is that a nasopharyngeal pH probe is equivalent to an esophageal probe in identifying laryngopharyngeal reflux.
