Abstract
Background: Laryngopharyngeal reflux (LPR) is a prevalent disorder. The aim of the present retrospective cohort study was to evaluate oropharyngeal pH-monitoring using a novel scoring system for LPR. Methods: In a total of 180 consecutive patients with possible LPR, reflux symptom index (RSI), reflux finding score (RFS), oropharyngeal pH-monitoring and transnasal esophagoscopy were carried out for further investigation. Results: In our series, 99 (55%) patients had severe LPR, 29 (16%) cases presented with moderate and 23 (13%) with mild severity, 9 (5%) subjects revealed neutral values, and 7 (4%) individuals were alkaline, while 13 (7%) patients had no LPR. In detecting LPR, the sensitivity, specificity and accuracy of oropharyngeal pH-monitoring was 95%, 93% and 94%, respectively. Conclusion: Oropharyngeal pH-monitoring is a reliable tool in the assessment of LPR, but the pH graphs have to be precisely analyzed and interpreted in context with other validated diagnostic tests.
