CORRELATION BETWEEN REFLUX SYMPTOM INDEX VERSUS REFLUX FINDING SCORE IN LARYNGOPHARYNGEAL REFLUX DISEASE

Abstract

Objective: To evaluate the correlation between Reflux Symptom Index (RSI) Versus Reflux Finding Score (RFS) and to find the prevalence of hypothyroidism in laryngopharyngeal reflux disease
Methods: This is a prospective, analytical study conducted from February 2022 to August 2022 among 75 patients in department of otorhinolaryngology, Shree Birendra hospital, Chaunni. RSI questionnaire with 9 questions were filled by the patients on 5 points scale. A score of more than 13 was considered diagnostic of LPR. RFS consists of scores from 0-4 determined by fiber-optic nasal endoscopy findings. Score more than 7 indicated LPR. Prevalence of hypothyroidism in all patients was calculated by evaluating serum thyroid function test
Results: The reflux symptom index was more than 13 on 41 patients with mean 13.28 ±3.95 and reflux finding score was more than 7 on 23 patients with mean 6.43±3.19 with statistically significant but with low correlation between reflux symptom index and reflux finding score ( p=0.027, r=0.25). The prevalence of hypothyroidism in laryngopharyngeal reflux was similar to general population.
Conclusion: There was low correlation between reflux symptom index and reflux finding score in patient with laryngopharyngeal reflux. The prevalence of hypothyroidism in these patient was similar to the general population.
