Otitis externa; chronic
Alternative names:
chronic otitis externa; ear infection, external - chronic; external ear infection - chronic; swimmer's ear - chronic
Treatment:
The goal of treatment is cure of the infection.
The ear canal should be cleaned of drainage to allow topical medications to work effectively.
Topical application of ear drops containing antibiotics to fight infection and corticosteroids to reduce itching and inflammation are usually effective. Ear drops should be used abundantly (four or five drops at a time) since too much is harmless while too little may not penetrate to the end of the ear canal. If the ear canal is very swollen, a wick may be placed in the ear to allow the drops to travel to the end of the canal. Fungal infections may be treated with antifungal powders applied to the external ear and canal.
Occasionally, oral medications may be used in addition to the topical medications. Analgesics may be used if pain is severe. Warmth to the ears may reduce pain.
Protect ears from further damage. Do not scratch the ears or insert cotton swabs or other objects in the ears. Keep ears clean and dry, do not let water enter when showering, shampooing, or bathing. A 1:1 mixture of rubbing alcohol and distilled vinegar in the ear canal will help dry it out and prevent recurrences.
Expectations (prognosis):
Chronic otitis externa usually responds to treatment. Treatment may be prolonged or repeated. If untreated, complications may develop.
Complications:
Calling your health care provider:
Call for an appointment with your health care provider if symptoms of chronic otitis externa develop; or if acute otitis externa does not respond to treatment.
Call your health care provider if symptoms do not respond to treatment, or if persistent infection or other new symptoms develop.
