Why are children under 2 years old more prone to otitis media?

• A. Longer Eustachian tubes.
• B. Higher pain tolerance.
• C. Shorter Eustachian tubes.
• D. Immature immune system.

Answer: (C)

A key idea is how the Eustachian tube differs in young children. In infants, the tube is shorter, wider, and more horizontal, with looser surrounding tissues. This makes it easier for bacteria from the nasopharynx to travel into the middle ear and harder for fluid to drain out. Those factors raise the risk of middle ear infections, especially during viral upper respiratory infections that cause more secretions and inflammation.

While an immature immune system contributes to susceptibility, the primary reason this age group is more prone is the shorter, more horizontal Eustachian tube. Longer tubes would improve drainage and reduce risk, and having a higher pain tolerance doesn’t drive infection risk.
