This 11-year-old male had a hearing screening at school and was then referred to me for further evaluation. History includes middle ear pathology 2 years ago due to ear infections. At this time the left canal and TM are clear. The right TM is obscured due to cerumen.

A tympanometry was conducted using a tympanometer and found to be consistent with normal middle ear pressure and mobility. Hearing is adequate. No further evaluation at this time.

Middle ear pathology is a condition that involves having a blocked sensation in one or both ears. It results in the ears discharging fluid from the ear canals, tinnitus, pain in the ears, and fever. The middle ear is made up of ossicles and the tympanic membrane. Diagnosis of this condition is made through a procedure known as tympanometry.

Step-by-step explanation

Tympanometry aims at measuring the mobility of the eardrum, measuring middle air pressure, and middle ear volume. To determine the ear's conditions, the test is done by creating variations of pressure in the ear. This causes the eardrum to vibrate, and the results are recorded on a graph. The normal middle ear pressure should be between + 50 and -50 dePa.
