Otitis
''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'', external otitis, or "swimmer's ear" involves the outer ear and ear canal. In external otitis, the ear hurts when touched or pulled. * ''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 sensory organs for balance and hearing. When the inner ear is inflamed, ''vertigo'' is a common symptom.
