Otitis is a general term for inflammation or infection of the ear, in both humans and other animals. It is subdivided into the following:
Otitis externa or
External Otitis - involves the
outer ear and
ear canal. In External Otitis, the ear hurts when touched or pulled. This condition is often called "swimmer's ear".
Otitis media or Middle Ear Infection- involves the
middle ear. In Otitis media, the ear is infected or clogged with fluid behind the ear drum, in the normally air-filled middle-ear space. This very common childhood infection sometimes requires a surgical procedure called "myringotomy and tube insertion".
Otitis interna or
Labyrinthitis- involves the
inner ear. The Inner Ear includes sense organs for balance and hearing. When the inner ear is inflamed,
vertigo ("room spinning") is a major symptom.
