Otitis Externa

Swimmer's Ear

Otitis externa is more commonly known as swimmer's ear. This condition and the resulting earache (Read about "Earache") stem from an infection of the ear canal. (Read about "The Ear and Hearing") Symptoms can include:

• itching
• redness
• discomfort
• fluid drainage
• feeling of fullness in the ear
• decreased hearing

In severe cases, there may be visible swelling of the ear or fever.

Otitis externa often occurs when the ear remains moist for an extended period of time. This allows bacteria to affect the skin of the ear canal. Adults and children who swim often are at increased risk. The risk is especially high if there are bacteria in the water where they swim. Bacteria can also affect the skin if the ear canal is scratched or irritated. While otitis externa is most often bacterial, it can also result from fungal or viral infection. (Read about "Microorganisms") People with skin conditions such as eczema are also more prone to otitis externa. (Read about "Eczema and Dermatitis")

If you suspect you or your child has otitis externa, it's very important to see a doctor. Possible complications of untreated otitis externa can include hearing loss (Read about "Hearing Loss") or more severe infection. A doctor will examine the ear canal, and make sure there is no damage to the eardrum. In most cases, the ear will be cleaned, and then eardrops will be used to treat the infection and reduce inflammation. If you are given oral antibiotics (Read about "Antibiotics") be sure to follow your doctor's directions carefully. If there is damage beyond the ear canal, you can be referred to an otolaryngologist.

There are things you can do to reduce the risk of developing otitis externa. After swimming, for example, turn your head to each side to let water drip out of the ears, and then dry your ears with a soft towel. You should never put foreign objects, such as a cotton swab, into the ear.
