This is a 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)
