Ear infections are more common in children because their eustachian
tubes are shorter, narrower, and more horizontal than in adults,
making the movement of air and fluid difficult. Bacteria can become
trapped when the tissue of the eustachian tube becomes swollen from
colds or allergies. Bacteria trapped in the eustachian tube may
produce an ear infection that pushes on the eardrum causing it to
become red, swollen, and sore.
