Abstract:
LaryngoPharyngeal Reflux (LPR) is characterized by symptoms, signs, and/or tissue damage resulting from the aggression of the gastrointestinal contents in the upper airways. The Reflux Finding Score (RFS) assesses the laryngeal signs through laryngoscopy. The Reflux Symptom Index (RSI) scores the LPR symptoms. The objective of this real-world study was to compare RFS with RSI in a cohort of Italian LPR patients. Globally, 3932 patients with LPR were evaluated and RFS and RSI were assessed in all subjects. A moderate correlation was found between RSI and RFS (r=0.484, p<0.0001). In conclusion, the RSI and RFS can easily be included in the LPR work-up as objective and consistent parameters, with low cost and high practicality. Based on these clinical outcomes, the specialist can easily use these tests in clinical practice.
