Otitis externa, also called “swimmer’s ear”, is an inflammation of the external canal of the ear. This inflammation usually causes pain, more or less intense. These are accompanied by irritation and itching. Appropriate treatment can limit the evolution of the disease.
Definition of otitis externa
Otitis externa is characterized by inflammation (redness and swelling) of the external canal of the ear. The latter is a canal located between the outer ear and the eardrum. In the majority of cases, only one of the two ears is impacted.
This affection of the outer ear is also called: Otitis of the bather. Indeed, frequent and / or prolonged exposure to water may be at the origin of the development of such otitis.
The most common clinical signs of otitis externa are:
