What is otitis externa (swimmer's ear)?
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.
What causes swimmer's ear?
Many different factors can increase your child's chance of developing swimmer's ear. As the name implies, one of the factors is excessive wetness as with swimming, although it can occur without swimming. Other possible causes of this infection include the following:
Being in warm, humid places
Harsh cleaning of the ear canal
Trauma to the ear canal
Dry ear canal skin
Foreign body in the ear canal
Excess cerumen (ear wax)
Eczema and other forms of dermatitis
What are the symptoms of swimmer's ear?
The following are the most common symptoms of swimmer's ear. However, each child may experience symptoms differently. Symptoms may include:
Redness of the outer ear
Itching in the ear
Pain, especially when touching or wiggling the ear lobe that may spread to the head, neck, or side of the face
Drainage from the ear
Swollen glands in the upper neck or around the ear
Swollen ear canal
Muffled hearing or hearing loss
Full or plugged-up feeling in the ear
The symptoms of swimmer's ear may resemble other medical conditions or problems. Always consult your child's health care provider for a diagnosis.
How is swimmer's ear diagnosed?
Swimmer's ear may be diagnosed with a complete medical history and physical examination by your child's health care provider. He or she may use an otoscope, a lighted instrument that helps to examine the ear and to aid in the diagnosis of ear disorders. This will help your child's health care provider know if there is also an infection in the middle ear, called otitis media. Although this infection usually does not occur with swimmer's ear, some children may have both types of infections.
Your child's health care provider may also take a culture of the drainage from the ear to help determine proper treatment.
Treatment of swimmer's ear
Swimmer's ear, when properly treated by a health care provider, usually clears up within seven to 10 days. Specific treatment for swimmer's ear will be determined by your child's health care provider based on:
Your child's age, overall health, and medical history
Extent of the condition
Your child's tolerance for specific medications, procedures, or therapies
Expectations for the course of the condition
Your opinion or preference
Treatment may include
Antibiotic ear drops
Corticosteroid ear drops (to help decrease the swelling)
Keeping the ear dry, as directed by your child's health care provider
