This is an objective test of your middle ear function and is useful for determining whether:
- there is any fluid or congestion in your middle ear
- there is a perforation (hole) in your eardrum
- the eardrum is flaccid and weak
- there is loss of continuity of the ossicles (middle ear bones) by disease or trauma
- a grommet is blocked
- changing pressure in the ear canal causes dizziness indicating a fistula (defect) in the bone surrounding the labyrinth (balance organ)
You are not required to do anything for this test other than sit very still. The audiologist will hold a soft rubber probe at the entrance of your ear canal and you may feel a slight change of pressure in your ear.
