Tympanograms assess problems in the middle ear by measuring the stiffness of the eardrum. It checks for fluid and negative pressure in the middle ear, and possible problems with the ossicles and tympanic membrane.

The device is placed in your ear and a small amount of pressure is applied inside the middle ear.  The tympanogram records the results on a graph.

During the test, it’s important to remain still since any movement can change the pressure in the middle ear and affect the test results.  You may also feel some slight discomfort but this is normal.
