A home ear examination is a visual
inspection of the ear canal and eardrum using an instrument called an otoscope. An otoscope is a handheld instrument with a
light, a magnifying lens, and a funnel-shaped viewing piece with a narrow,
pointed end called a speculum.
A home ear examination can help
detect many ear problems, such as ear infections, excessive earwax, or an object in the ear canal.
After receiving instructions and training from a doctor,
home ear examinations can be helpful for parents of young children who
frequently get ear infections and earaches. Sometimes a child may have an ear
infection in which the only outward symptom may be fussiness, a fever, or
tugging at the ear. A home ear examination may help reveal the cause of these
symptoms. But it can be hard to learn to use an otoscope, and some otoscopes are of poor quality. An examination
with a doctor is often necessary.
Why It Is Done
A home ear examination may be done
Look for signs of infection when a person has
an earache or when a young child has vague symptoms.
Check for a
foreign object in the ear, such as an insect or a bean.
earwax buildup when a person complains of hearing loss or of fullness or
pressure in the ear.
How To Prepare
No special preparation is needed
before having this test. Always remember to clean the ear speculum in hot,
soapy water before using it.
How It Is Done
If you are going to examine a young
child, have the child lie down with his or her head turned to the side, or have
the child sit on an adult’s lap and rest his or her head on the adult’s chest.
Older children or adults can sit with their head tilted slightly toward the
opposite shoulder. Sitting is the best position for identifying otitis media with effusion (fluid behind the eardrum).

If the person is only having problems with one ear,
examining the other ear first may make it easier to determine what is different
about the affected ear.
When checking the ear of a child older
than 12 months or an adult, hold the otoscope in one hand and use your free
hand to pull the outer ear gently up and back. This straightens the ear canal
and improves visualization. In babies younger than 12 months, gently pull the
outer ear down and back.
insert the pointed end of the viewing piece into the ear canal while looking
into the otoscope. The sides of the ear canal can be quite sensitive, so try
not to put pressure on the ear canal. It may help to steady your hand on the
person’s face so your hand moves along with their head in case they move
Do not move the otoscope forward without looking into
it. Make sure you can see the path through the ear canal. You do not need to
insert the viewing piece very far into the ear-the light extends well beyond
the viewing tip.
Angle the tip of the viewing piece slightly
toward the person’s nose to follow the normal angle of the canal. While looking
through the otoscope, move it gently at different angles so that you can see
the canal walls and eardrum. Stop at any sign of increased pain. If your view
is blocked by earwax, see the topic Earwax for tips.
Ask your doctor to review this technique with you and to watch you do an
examination. Then practice on some healthy, willing adults so you can learn
what a normal ear canal and eardrum look like. Don’t be discouraged if you
can’t see the eardrum at first-it takes some practice and experience.
How It Feels
Examining a healthy ear using an otoscope
is usually painless but may cause some mild discomfort if the person being
examined has an ear infection.
The pointed end of the otoscope can irritate the
lining of the ear canal. Make sure that you insert the otoscope slowly and
carefully. If you do scrape the lining of the ear canal, it rarely causes
bleeding or infection, but you must be careful to avoid pain or injury.
An otoscope can push an object closer to the eardrum. If you suspect an
object in the ear, do not move the otoscope forward once you see the object.
Don’t try to remove the object-seek medical help.
There is a
slight risk of damaging the eardrum if the otoscope is inserted too far into
the ear canal. Do not move the otoscope forward if it feels like something is

What Affects the Test
Reasons why the results of the
test may not be helpful include:
small child who is upset or crying may have red eardrums. It is easy to confuse
this redness with an ear infection.
What To Think About
Some home otoscopes use sound waves that bounce
off the eardrum to detect otitis media with
effusion (fluid in the middle ear).
Earwax (cerumen) is a normal protective secretion of the
ear canal. Earwax normally drains by itself, and cleaning the outside of the
ear is all that is necessary. Never clean your ear canals with cotton swabs,
hairpins, paper clips, or your fingernail, which may damage the canal or
eardrum and can push the wax farther into the canal. For information on how to
remove earwax, see the topic Earwax.
Regardless of what you see with a otoscope, call your
doctor if you or your child has:
Severe ear pain, especially if your child has a
