Acute otitis media (AOM) is a common, symptomatic infection of the middle ear. Nasopharyngeal secretions that contain viruses and bacteria can enter the middle ear via the eustachian tube. Usually the middle ear drains well but if there is eustachian tube swelling, fluid from the middle ear may not drain properly. Under these conditions bacteria and viruses present in the middle ear can multiply, creating clinical AOM.
