What anatomical feature predisposes children to recurrent otitis media?

• A. Longer Eustachian tubes
• B. Narrow nasal passages
• C. Shorter and more horizontal Eustachian tubes
• D. Immature cochlea

Answer: (C)

Recurrent otitis media in children stems from how the Eustachian tube is shaped and functions in kids. In children the tube is shorter, more horizontal, and more easily obstructed, which impairs ventilation and drainage of the middle ear. When the tube can’t ventilate properly, negative pressure develops, fluid can accumulate, and bacteria from the nasopharynx can reach the middle ear, leading to infections that recur, especially after upper respiratory infections. In contrast, a longer, more vertical Eustachian tube in adults drains better and reduces this risk. Narrow nasal passages aren’t the primary driver, and an immature cochlea isn’t related to this predisposition.
