The eardrum separates the middle and outer ears. The middle ear contains the bones that link the eardrum to the inner ear. The inner ear contains the balance organs and the nerves vital to hearing.

Outer ear infections can be chronic (lasting 3 or more months) or acute (short-term) and are more commonly affect in children 7 to 12 years of age, people in warm and humid climates, people who swim, and people who use devices that protect hearing. Infection of the outer ear is also called swimmer’s ear. It’s rarely serious.
