Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
