Otitis Externa occurs when the ear gets wet and does not dry out. Wax deep in the canal can trap water and result in an infection.
Otitis Media can occur when water gets in the ear through a hole in the ear drum. More commonly, it follows an upper respiratory infection. Swelling and infected mucus in the nose and nasopharynx, (space behind the nose where the adenoids are located) causes swelling of the eustachian tube and failure to “pop” one's ears with swallowing. The resultant vacuum draws infected fluid into the middle ear.
