Repeated ear infections are very common in children younger than 6 years of age. While many of them will outgrow their tendency to get repeated ear infections by the age of 7, some of them due to immature immune system and poor function of the eustachian tube are at increased risk of repeated ear infections and persistence of fluids in the middle ear. Eustachian tube is a narrow tube connecting middle ear with the back of the nose. It normally equalizes middle ear pressure and helps in drainage of secretions from the middle ear into the nasopharynx. In kids, Eustachian tube is narrower and more horizontal as compared to the adults and these makes it more prone to occlusion and its dysfunction.
