Ear Examination

How It Is Done continued...

Your doctor will gently pull your ear back and slightly up to straighten the ear canal. If a baby under 12 months is being examined, the ear will be pulled downward and out to straighten the ear canal. The doctor will then insert the pointed end (speculum) of the otoscope into your ear and gently move the speculum through the middle of your ear canal to avoid irritating the canal lining. The doctor will look at each eardrum (tympanic membrane).

Using a pneumatic otoscope lets your doctor see what the eardrum looks like and how well it moves when the pressure inside the ear canal is changed. And it helps the doctor determine if there is a problem with the eustachian tube or fluid behind the eardrum (otitis media with effusion). A normal eardrum will flex inward and outward in response to the changes in pressure.

How It Feels

The physical examination of the ear using an otoscope is usually painless. If you have an ear infection, inserting the otoscope into the ear canal may cause some pain or mild discomfort.

Risks

The pointed end of the otoscope can irritate the lining of the ear canal, but this can usually be avoided by inserting the otoscope slowly and carefully. If the otoscope does scrape the lining of the ear canal, this rarely causes bleeding or infection.

Results
