Swimmer's ear - chronic

Definition

Swimmer's ear is inflammation, irritation, or infection of the outer ear and ear canal. Chronic swimmer's ear occurs when the condition does not go away or comes back multiple times.

Alternative Names

Ear infection - outer ear - chronic; Otitis externa - chronic

Causes

Swimmer's ear (otitis externa) is fairly common. It consists of inflammation, irritation, or infection of the outer ear and ear canal. Swimming in polluted water is one way to contract swimmer's ear. Moisture predisposes the ear to infection from water-loving bacteria such as Pseudomonas. Other bacteria, or rarely, fungus, can also cause infection. Swimming is not the only cause, however -- the condition can be caused by scratching the ear or an object stuck in it.

Chronic swimmer's ear may result from inadequate treatment, or may suggest the presence of a disease in underlying bone, a complication called malignant otitis externa.
