5 Acute otitis externa, noninfective.
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.
Acute otitis externa is a common condition involving inflammation of the ear canal. The acute form is caused primarily by bacterial infection, with Pseudomonas aeruginosa and Staphylococcus aureus the most common pathogens.
A disorder characterized by inflammation, swelling and redness to the outer ear and ear canal.
Otitis externa means that the inflammation is confined to the external part of the ear canal and does not go further than the eardrum. See the separate leaflet called Ear Infection (Otitis Media), for an infection of the middle ear.
The key physical finding of OE is pain upon palpation of the tragus (anterior to ear canal) or application of traction to the pinna (the hallmark of OE). Examination reveals erythema, edema, and narrowing of the external auditory canal (EAC), and a purulent or serous discharge may be noted (see the image below).
Otitis externa, also called swimmer's ear, is an inflammation, irritation, or infection of the external ear canal. Swimmer's ear is caused by fungi or bacteria. Water that remains trapped in the ear canal (when swimming, for example) may provide a source for the growth of bacteria and fungi.
The most common cause of otitis externa is a bacterial infection, although fungal overgrowth is a principal cause in 10 percent of cases. Otitis externa can also result from any of a broad range of noninfectious dermatologic processes.
Otitis externa (OE) is an inflammation, that can be either infectious or non-infectious, of the external auditory canal. In some cases, inflammation can extend to the outer ear, such as the pinna or tragus. OE can be classified as acute (lasts less than 6 weeks) or chronic (lasts more than 3 months).

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.
