Tympanometry Test

Tympanometry is a diagnostic test used to assess the condition of the middle ear and the mobility of the eardrum (tympanic membrane). It is a valuable tool for identifying various ear-related problems, particularly those involving the middle ear. Here's an overview of the tympanometry test:

Purpose:
Middle Ear Function Assessment:

• Evaluates the movement and flexibility of the eardrum and the conduction bones in the middle ear.

Detection of Middle Ear Pathologies:

• Identifies conditions such as otitis media (middle ear infection), Eustachian tube dysfunction, and other middle ear disorders.

Procedure:
Instrumentation:

• A tympanometer is used, which consists of a hand-held device with a probe and a pump.

Sealing of Ear Canal:

• The person typically sits or lies down.
• A small probe tip is inserted into the ear canal, creating an airtight seal.

Pressure Variation:

• The device changes the air pressure in the ear canal, causing the eardrum to move.

Measurement of Tympanic Membrane Movement:

• The tympanometer measures the amount of sound reflected off the eardrum at different pressures.

Graphical Representation:

• The results are displayed on a graph called a tympanogram.
• The tympanogram shows the compliance or movement of the eardrum at various pressure levels.
