Tympanometry is used to check the condition of the middle ear and the mobility of the ear drum (tympanic membrane). It is a quick and easy technique that is helpful in diagnosing problems such as “glue ear” or fluid behind the eardrum, a perforated eardrum and middle ear infections (Otitis Media).
High Frequency Tympanometry is also an examination of the middle ear but it accounts for the difference in anatomy of the middle ear in infants.
It is a more reliable test when checking for middle ear problems in infants and is usually part of a battery of tests, including:
Paediatric Hearing Assessment
Otoacoustic Emissions (OAE)
Auditory Brain Response (ABR)
