What is a tympanogram?

A tympanogram is a quick and easy test that can let your medical doctor know how well the eardrum moves when a soft sound and air pressure are introduced in the ear canal. It is most helpful in diagnosing problems in the middle ear (fluid behind the eardrum).
The technician will put a special probe-like earplug in your ear. Then the specialized equipment will automatically record the data.
In a healthy ear, the middle ear is filled with air at a pressure equal to the surrounding atmosphere. However, if the middle ear is filled with fluid, the eardrum will not vibrate properly, resulting in a flat tympanogram. If the middle ear is filled with air yet this air is at a higher or lower pressure than the surrounding atmosphere, it will result in a shift of position of the tympanogram.
