Otitis externa

Otitis externa

Otitis externa (also known as "External otitis" and "Swimmer's ear") is an inflammation of the outer ear and ear canal.

Inflammation of the skin of the ear canal is the essence of this disorder. The inflammation can be secondary to dermatitis (eczema) only, with no microbial infection, or it can be caused by active bacterial or fungal infection. In either case, but more often with infection, the ear canal skin swells and may become painful or tender to touch.
