Otitis Externa (Swimmer's Ear)

Swimmer’s ear (otitis externa) is an inflammation of the external ear canal. Swimmer’s ear is caused by fungi or bacteria. Water that stays in the ear canal during swimming, for example, may let bacteria and fungi grow.

Many different things can make it more likely for your child to get swimmer's ear. Swimming or being in other wet, humid conditions are common causes. Other possible conditions that may lead to the development of swimmer's ear include:

• Rough cleaning of the ear canal
• Injury to the ear canal
• Dry skin in the ear canal
• Foreign object in the ear canal
• Excess earwax
• Skin conditions such as eczema and other kinds of dermatitis

Children are more likely to get swimmer’s ear if they:

• Go swimming for long periods of time, especially in lake water. It is less likely to occur in appropriately maintained recreational pools or the ocean
• Fail to remove excess moisture after swimming
• Have an injury to the ear canal, from cleaning it too often or scratching it
• Use hearing aids, earphones or swimming caps
• Have skin irritation from allergies or other skin conditions
• Have a narrow ear canal

Swimmer’s ear can cause the following symptoms:

• Redness of the outer ear
• Itching in the ear
• Pain, especially when touching or wiggling the ear lobe
• Drainage from the ear
• Swollen glands in the neck
• Swollen ear canal
• Muffled hearing or hearing loss
• Full or plugged-up feeling in the ear

The symptoms of swimmer's ear may look like other health conditions. Make sure your child sees his or her health care provider for a diagnosis.

Your child’s health care provider will ask questions about your child’s health history and current symptoms. He or she will examine your child, including the ears. The provider may use a lighted instrument called an otoscope to look in your child’s ear. This will help the 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 figure out the best treatment.

Treatment will depend on your child’s symptoms, age and general health. It will also depend on how severe the condition is.
Swimmer’s ear, when properly treated by a health care provider, usually clears up within 7 to 10 days. Treatment may include:

• Antibiotic ear drops
• Corticosteroid ear drops
• Pain medicine
• Keeping the ear dry

Complications of swimmer’s ear include:

• Temporary hearing loss from a swollen and inflamed ear canal
• Ear infections that keep coming back
• Bone and cartilage damage
• Infection of the tissue around the ear 
• Infections that spread from the ear to the bones of the head or skull

The following are some tips to help prevent swimmer’s ear:

• Use ear plugs for swimming or bathing
• Gently clean your child’s ear canal
• Dry ears well, especially after swimming
• Don't use cotton swabs (Q-tips) in the ears

Another tip to help dry the ears is to use a hair dryer set to the low or cool setting. Hold the dryer at least 12 inches from your child’s head. Wave the dryer slowly back and forth. Don’t hold it still.

Your child’s health care provider may recommend drops to help dry the ears.
