Swimmer's Ear (Otitis Externa) and More Causes
When water gets into the ear, it may bring in bacterial or fungal particles. Usually the water runs back out; the ear dries out; and the bacteria and fungi don’t cause any problems. But sometimes water remains trapped in the ear canal, and the skin gets soggy. Then bacteria and fungi grow, flourish, and can infect the outer ear.
If you experience these symptoms or if glands in the neck become swollen, see your doctor.
If your ear feels moist or blocked after swimming, hair washing, or showering, tilt your head sideways with that ear up, pull the ear upward and backward to put in eardrops to dry out the ear. Wiggle your ear to get the drops all the way down in the ear canal, and then turn your head to let them drain out. These eardrops are sold without prescription; check with your pharmacist.
WARNING: If you have an ear infection, have had a perforated or otherwise injured eardrum, or ear surgery, you should consult an ear, nose, and throat specialist before swimming or using any type of ear drops. If you don’t know if you have ever had a perforated, punctured, ruptured, or otherwise injured eardrum, ask your doctor. If your doctor says it is safe, make up your own ear drops to use after swimming. Many doctors recommend rubbing alcohol as part of the mixture. As the alcohol evaporates, it absorbs the water, helps dry out the ear, and may even kill the bacteria and fungi that cause swimmer’s ear. Another effective ingredient is boric acid powder (2 tsp./pint) or white vinegar (mixed 50/50 with alcohol). A weak acid environment discourages the growth of bacteria and fungi.
A dry ear is least likely to get infected. Efforts to remove water from your ear should be limited to the drying effects of alcohol or, if you have a perforated eardrum, a hair dryer. You should not use cotton swabs (Q-tips) because they pack material deeper in the narrow ear canal, irritate the thin skin of the ear canal, and make it “weep” or bleed.
If yours is a frequently recurring problem, your otolaryngologist (ENT doctor) may recommend placing oily (or lanolin) ear drops in your ears before swimming to protect them from the effects of the water.
People with itchy, flaky ears or ears that have wax build up are very likely to develop swimmer’s ear. They should be especially conscientious about using the alcohol ear drops as described whenever water gets trapped into the ears. It may also help to have ears cleaned out each year before the swimming season starts.
Why Do Ears Itch?
An itchy ear is maddening. Sometime it is caused by fungus, or allergies, but more often it is a chronic dermatitis (skin inflammation) of the ear canal. One type is seborrheic dermatitis, a condition similar to dandruff; the wax is dry flaky, and abundant. Patients should avoid foods that aggravate it, such as greasy foods, sugars and starches, carbohydrates and chocolate. Doctors often prescribe a cortisone eardrop at bedtime when ears itch. There is no long-term cure, but it can be controlled.
What about Gnats or Other Insects?
Many types of insects get into the ears. Gnats get tangled in the wax and can’t fly out. Bigger insects can’t turn around; neither can crawl back out. They keep on struggling though, and their motion can be painful and frightening.
Wash out gnats with warm water from a rubber bulb syringe. (Remember to dry the ear afterwards with alcohol drops.) For a bigger insect, the first step is to fill the ear with mineral oil, which plugs off the breathing pores of the insect and kills it. It may take 5-10 minutes. See your doctor to have the insect removed; don’t try to do it yourself.
What About Other Foreign Objects?
Beads, pencil lead, erasers, bits of plastic toys and dried beans are common objects that children put into their ears. Removal is a delicate task that must be performed by a doctor.
What is Otolaryngology– Head and Neck Surgery?
An otolaryngologist is a physician concerned with the medical and surgical treatment of the ears, nose, throat, and related structures of the head and neck.
The American Academy of Otolaryngology – Head and Neck Surgery, Inc. represents more than 7,500 ear, nose, and throat specialists. For more information or a list of otolaryngologists practicing in your area, please contact the Academy.
