With the onset of fall and the cold and flu season, many children will
develop ear infections.
What is an ear infection, and how do kids get them?
The most common type of ear infection in young children is acute otitis
media (AOM), which occurs in the middle ear, or the space behind the
eardrum. Typically, the child's eustachian tubes (the tiny ducts that
connect the middle ear to the back of the nose and throat) become swollen,
causing fluid to pool in the middle ear. A virus or bacteria then infect the
trapped fluid. As pus accumulates in the middle ear, the increased pressure
on the eardrum causes an earache. Annually, there are 24.5 million visits to
physicians for otitis media.
Why are middle-ear infections so common in babies and toddlers?
There are several factors that make children between three months and 3
years of age easy targets.
Their immune systems aren't yet mature enough to defend against colds and
other viral infections.
Their eustachian tubes tend to be short and somewhat horizontal (in
adults, its longer and more vertical), so it's easy for germs to travel from
the nose or throat into the middle ear.
Their eustachian tubes also ten to be narrow, so even a small amount of
swelling in response to a cold or other respiratory illness can trap fluid
in the middle ear and create a breeding ground for bacteria.
What are the risk factors for ear infections?
Gender. Boys have more infections than girls do.
Ethnic background. Caucasian and Native American children have higher
rates of OM than children from other ethnic groups do.
Age of onset. The younger a child is when an ear infection first develops,
the more likely he or she will have repeated infections.
Tobacco smoke. Children exposed to second-hand smoke have a higher risk of
developing ear infections.
Family history. If a parent or sibling had ear infections, the child's
risk is greater.
Allergies. Allergies that cause a stuffy nose are sometimes linked to ear
infections.
Bottle-feeding. Babies who are bottle-fed, especially lying on their back,
have more infections than those who are breastfed.
Child care. Children in group child-care settings are exposed to more
germs and viruses.
How do I know if my child has an ear infection?
The first step is to know the symptoms of OM. They are:
Irritability
Head-shaking or pulling on the ear
Fever
Loss of appetite
Disturbed sleep
Decreased attentiveness
Temporary hearing loss
What should I do if I think my child has an ear infection?
1. Call your pediatrician. He or she will examine your child's ears with an
otoscope. In some cases, your pediatrician may also perform a tympanometry
test or check your child's hearing.
2. Stay with the treatment your doctor prescribes. A typical treatment may
be a 5-10 day course of antibiotics. However, when children take antibiotics
they don't need, it promotes the development of drug-resistant bacteria.
Some pediatricians may wait a day or two to see if the infection clears up
on its own.
3. Usually, the ear pain and fever associated with ear infections disappear
within two days of starting the antibiotic. However, fluid can remain in the
middle ear for several weeks or even months. You will want to schedule a
follow-up exam with your pediatrician to make sure the infection clears up.
4. If your child has fluid in the ears for three months or longer, referral
to an ear specialist and hearing testing is recommended.
The Sight & Hearing Association has developed a new Ear Infection Tracking
Card, a handy tool to help you keep track of your child's ear infections.
This tri-fold card is the size of a driver's license and fits perfectly into
a wallet or purse. If you would like us to mail a card to you, please send
