OBJECTIVES: Laryngopharyngeal reflux (LPR) is well documented in children. However, methods of obtaining accurate diagnosis are controversial. As a prelude to establishing normative values in children, we retrospectively reviewed comparison data of 63 consecutive children tested by pH probe and post-cricoid biopsy.
RESULTS: Of the 63 total patients (age 6 months-17 years), 37 (60%) were positive for reflux by probe with a negative biopsy. Eleven (17%) tested negative to probe and biopsy. Ten (15%) were excluded (pulled probe). Five (8%) were positive by probe and biopsy.
CONCLUSION: Normative values in children have not been determined in this instrument. We believe it may offer a satisfactory diagnostic tool. These results, and previous studies, suggest that pH probe testing is superior to histologic diagnosis in determining LPR. However, normative values must be determined in children prior to further comparative studies.
