Ear Infections (Otitis Media)



Screening/Diagnosis:

If a child has a suspected ear infection, the doctor will ask questions regarding the child’s health. Questions like, has the child had a head cold or sore throat recently? Is he or she having trouble sleeping? Is he or she pulling at his or her ears? If an ear infection seems likely, the simplest way for a doctor to tell is to use a lighted instrument, called an otoscope, to look at the eardrum. A red, bulging eardrum indicates an infection.

A doctor also may use a pneumatic otoscope, which blows a puff of air into the ear canal, to check for fluid behind the eardrum. A normal eardrum will move back and forth more easily than an eardrum with fluid behind it.
Tympanometry, which uses sound tones and air pressure, is a diagnostic test a doctor might use if the diagnosis still is not clear. A tympanometer is a small, soft plug that contains a tiny microphone and speaker as well as a device that varies air pressure in the ear. It measures how flexible the eardrum is at different pressures.
