Otitis externa, also called swimmer's ear, is an inflammation of the external ear canal. Swimmer's ear is caused by bacteria or yeast (fungus). Water that remains trapped in the ear canal (when swimming, for example) may provide a source for the growth of bacteria and yeast.

Swimmer's ear may be diagnosed with a complete medical history and physical examination by your child's physician. Your child's physician may use an otoscope, a lighted instrument that helps to examine the ear and aids in the diagnosis of ear disorders. This will help your child's physician know if there is also an infection in the middle ear, called acute otitis media. Although acute otitis media usually does not occur with swimmer's ear, some children may have both types of infections.

Swimmer's ear, when properly treated by a physician, usually clears up within seven to 10 days. The specific treatment for this condition depends on many factors and is tailored for each child. Please discuss your child's condition, treatment options and your preferences with your child's physician or healthcare provider.
