A middle-ear analysis measures the movement of the middle ear, and how sound travels through it. This can help to identify the presence of fluid or congestion (e.g. glue ear) and abnormal pressure related to infection or a perforation of the ear drum. These irregularities may explain your hearing loss symptoms or the presence of a pressurised sensation in the ear drum, middle ear bones or Eustachian tube.
Tympanometry is an objective assessment and is generally regarded as a quick and simple procedure. Your audiologist will insert a probe into the ear canal, which measures the level of pressure present, as well as the compliance of the ear drum.
The results of the examination are recorded on a graph called a tympanogram, enabling us to analyse and refer you for further testing if required.
A second middle-ear examination, called Acoustic Reflex Threshold, is usually carried out immediately after. Using the same probe, you will hear beeps that are progressively louder. You will not need to respond. Instead, the machine will automatically measure the response and the results are recorded.
