OBJECTIVES: To determine the utility of the new Restech pH-probe in diagnosis of laryngopharyngeal reflux by showing that patients with higher Reflux Symptom Indices and Reflux Finding Scores will have positive Restech studies.
RESULTS: Twenty patients were included in the study. Of these, thirteen patients (65%) had positive pH events during Restech evaluation. Sixteen patients (80%) of patients had Reflux Symptom Index of 10 or greater. Eighteen patients (90%) had Reflux Finding Scores of 7 or greater. There was a trend toward a higher scores and indices in the patients (n=9) with the abnormal Restech results, but this difference did not reach significance when all patients were included. When those patients who had diffusely elevated review of systems (greater than 10 complaints) were excluded, those patients with abnormal Restech (n=6) had significantly higher scores and indices (p=0.047 and p=0.030, respectively) than those patients with normal studies (n=10).
CONCLUSION: The Restech pH-probe may be a useful diagnostic tool for patients with laryngopharyngeal reflux in correlation with symptoms and examination findings.
