ABSTRACTBackground: Laryngopharyngeal reflux is associated with Eustachian tube dysfunction| (ETD), nowadays, there are few studies about this topic, so, it is required to study the relationship between both diseases.
Objective: To analyze the relationship of laryngopharyngeal reflux with the diagnosis of Eustachian tube dysfunction.
Material and Method: A study of cases and controls was done from July to December 2015, including patients with ETD and subjects without the disease, matched by age and gender. A tubal function test was performed to verify the presence or absence of ETD. All patients were subjected to the Reflux Symptom Index and the Reflux Finding Score.
Results:There were included 31 patients and 31 control subjects. The score was higher in patients with ETD in the Reflux Symptom Index (13.51 vs 9.80 points, p = 0.15) and in the Reflux Finding Score (6.48 vs 4.61 points, p = 0.07). There was a greater presence of LPR in patients with ETD compared with patients without ETD (OR = 4.28, 95% IC: 1.30-14.07, p = 0.01).
Conclusions: The presence of LPR in patients with ETD was significantly higher than in healthy patients, with four times more likely of suffering ETD associated to LPR.
