How is a middle ear infection diagnosed?

Your healthcare provider will
review your health history and do a physical exam. He or she will check the outer ear
and the eardrum using an otoscope. The otoscope is a lighted tool that lets the
healthcare provider see inside the ear. A pneumatic otoscope blows a puff of air into
the ear to test eardrum movement. When there is fluid or infection in the middle ear,
movement is decreased.

Your provider may also do a tympanometry. This is a test that directs air and sound to the middle ear.

If you have ear infections often, your healthcare provider may suggest having a hearing test.
