Introduction: Gastroesophageal reflux disease (GERD) is the clinical term that refers to excessive gastro-esophageal reflux that causes symptoms and harm. Laryngopharyngeal reflux (LPR) is the retrograde ascent of gastric content into the oropharynx and nasopharynx, which causes otorhinolaryngological manifestations. Objectives: 1. To determine the degree of association between the presence of pathologic GERD and/or LPR and the presence of otorhinolaryngological manifestations in pediatric patients who consulted at a private facility over a period of 10 years. 2. To determine the risk factors present in patients with a diagnosis of pathological GERD and/or LPR. Methodology: An observational study of cases and unmatched controls, investigating the association between pathologic and/or RFL and the presence of otorhinolaryngological manifestations in 22 patients (cases) and 22 controls. For analysis descriptive statistics, statistical tests of Chi square, and the Fisher exact test were used to analyze qualitative variables with Student's t test to analyze quantitative variables. Independent variables were verified using the calculation of odd ratio (OR) for unpaired data, the confidence interval (CI 95%) and the p value. Results: Otorhinolaryngological manifestations occurred in 33 patients, corresponding to 75% of the total sample; analysis found observed manifestations to be 17.5 times more probable in cases than in the controls (p=0.005). No association was seen to the presence or absence of any risk factor; however allergies (allergic rhinitis) was associated 4.5 times more often in cases (p=0.03). Conclusion: Based on this study we can state that there is a close relationship between the presence of pathological GERD and/or LPR and the appearance of ENT manifestations.
