A study of relationship between reflux symptom index and reflux finding score in patients with laryngopharyngeal reflux

Background: Diagnosis of laryngopharyngeal reflux (LPR) is considered as a challenge by otorhinolaryngologists. Reflux symptom index (RSI) and reflux finding score (RFS) are two diagnostic tools which yield in the diagnosis of LPR. The aim of the study was to establish an association between RSI and RFS in patients with LPR. Materials and Methods: A cross-sectional analytical study was conducted on 30 patients who were enrolled. RSI score and RFS were obtained as per pro forma. RSI score ≥13 and RFS ≥7 were indicated to be positive for LPR. Results: Of the 30 patients enrolled, males and females were 16 and 14, respectively. Mean RSI score was 23.83 (standard deviation [SD] = 9.07) and mean RFS was 16.07 (SD = 7.31) were obtained. The most common presenting symptom was lump in the throat (80%) and the sign was hyperemia/erythema (83.33%). A strong correlation of 0.86 (P = 0.01) was established between RSI and RFS. Conclusion: LPR plays a key role in patients with laryngeal complaints. RSI and RFS can be implemented easily in the diagnosis of LPR.
