Otitis externa is a condition that causes inflammation (redness and swelling) of the external ear canal, which is the tube between the outer ear and eardrum. Otitis externa is often referred to as "swimmer's ear" because repeated exposure to water can make the ear canal more vulnerable to inflammation.

Necrotizing (malignant) Otitis Externa – An infection that extends into the deeper tissues adjacent to the EAC. It primarily occurs in adult patients who are immunocompromised (e.g., as a result of diabetes mellitus or AIDS), and is rarely described in children. May result in cases of cellulitis and osteomyelitis.
Otomycosis – Infection of the ear canal secondary to fungus species such as Candida or Aspergillus. Complete clinical documentation should indicate the type of otitis externa, such as noninfective, actinic, chemical, contact, eczematoid, infective, reactive, or malignant, as well as the laterality (right, left, bilateral) ...
Otitis externa is commonly known as “swimmer’s ear” and usually is caused by bacteria invading the skin inside the ear canal. Symptoms are usually mild, at first, but may worsen without treatment. Doctors often classify swimmer’s ear according to mild, moderate, and advanced stages of progression.#N#Mild signs and symptoms:
Advanced progression signs and symptoms include: Severe pain that may radiate to face, neck, or side of the head. Complete blockage of ear canal. Redness or swelling of outer ear.
Chronic Otitis Externa – The same as acute diffuse OE, but of greater than six weeks’ duration. Eczematous (eczematoid) Otitis Externa – Encompasses a variety of dermatologic conditions (e.g., atopic dermatitis, psoriasis, systemic lupus erythematosus, and eczema) that may infect the EAC.
