Topic Overview
Ear
pain in children may be a sign of an infection in the space behind the eardrum
(middle
ear
). Ear infections (otitis media) most commonly occur when
cold symptoms, such as a runny or stuffy nose and a cough, have been present
for a few days.
An ear infection may occur when the
eustachian tube swells and closes and fluid
accumulates in the middle ear. The combination of fluid and germs (from
bacteria or viruses) creates a perfect environment for an infection. Swelling
from the infection causes pain from increased pressure on the eardrum. The
pressure can cause the
eardrum to rupture (perforate). A single eardrum
rupture is not serious and does not cause hearing loss. Repeated ruptures may
lead to hearing loss.
Middle ear infections are more common in children than in adults.
Young children have short, soft, more horizontal eustachian tubes that are more
easily blocked than those of older children and adults.
Ear infection is the most commonly diagnosed
bacterial infection in children younger than age 7.
Almost all children will have at least one ear infection by the time they are 7
years old. Most ear infections occur in babies between the ages of 6 months to
3 years. After age 7, ear problems may be related to inflammation, infection,
or fluid buildup in the middle or external ear. Ear infections are more common
in boys than in girls, and they most often occur in children who:
- Spend time in daycare settings.
- Are
bottle-fed.
- Use a pacifier.
- Live in households where
parents or caregivers smoke.
- Have had a previous ear
infection.
- Have problems present since birth (congenital
abnormalities), such as
cleft lip,
cleft palate, or
Down syndrome.
Fluid often remains in the middle ear (serous otitis,
or middle ear effusion) after an ear infection. This may cause no symptoms, or
it may cause a muffling of sound, decreased hearing, and mild discomfort. The
body usually reabsorbs fluid behind the eardrum within 4 to 8 weeks, and
hearing returns to normal.
Recurrent ear infections and persistent effusion may
occur in some children.
Even though ear infections are a common cause of ear pain, not all
ear pain indicates an infection. Other common causes of apparent ear pain in
young children include:
- Teething.
- A sore
throat.
- An accumulation of
earwax.
- An object in the
ear.
- Air pressure changes.
- Fluid buildup without
infection (serous otitis).
When evaluating ear pain in a child, remember that ear infections
commonly occur after symptoms of a cold have been present for a few days. When
other symptoms are present, ear pain or drainage may be less important than the
other symptoms.
Signs of a serious illness may indicate a problem that
requires immediate medical treatment.
Review the Check Your Symptoms section to determine if and when
your child needs to see a health professional.
