Laryngopharyngeal reflux: Comparing improvements in reflux symptom index with reflux finding score.

The objective of this study was to determine the correlation of reported symptom improvement in laryngopharyngeal reflux (LPR) with physical findings on laryngoscopic examination following medical therapy. This IRB-approved, retrospective, single-institution study included all patients who were diagnosed and medically treated for LPR from Jan. 1, 2015-October 21st, 2019. Only patients who received at least six weeks of treatment with a proton pump inhibitor and those with pre- and post-treatment Reflux Symptom Index; RSI (n = 91) and Reflux Finding Score; RFS (n = 33) were included in the study. A total of 91 patients were included in the analysis (61.54% female). There was a 19.99% improvement in total RSI (p = 0.0034) and a 25.20% improvement in total RFS (p = 0.0011) following at least six weeks of treatment (average = 253 ± 213 SD days). RSI symptoms were significantly decreased between pre- and post-treatment for hoarseness (p = 0.0005), clearing of the throat (p = 0.0066), excess throat mucus or postnasal drip (p = 0.0004), troublesome cough (p = 0.0231), and heartburn/chest pain (p = 0.0053). RFS demonstrated a statistically significant decrease in only subglottic edema (p < 0.0001) and ventricular obliteration (p = 0.0295). Pearson's correlation test did not demonstrate a relationship between RSI and RFS in the pre- and post-treatment analyses alone, but did demonstrate a statistically significant relationship when analyzed across all captured pre and post data (r = 0.265, p = 0.006). RSI and RFS are complimentary to one another when assessing for treatment response, but improvement in RSI does not correlate with that in RFS. Copyright © 2020. Published by Elsevier Inc.
