A New Nasopharyngeal pH Probe for Diagnosis of Laryngopharyngeal Reflux

NCT01308502 · Status: WITHDRAWN · Phase: PHASE4 · Type: INTERVENTIONAL

Last updated 2012-03-30

No results posted yet for this study

Summary

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.
