    Signs and tests

    An ear exam may show a pocket or perforation (opening) in the eardrum, often with drainage. The deposit of old skin cells may be visible with a microscope or an otoscope, a special instrument to view the ear. Sometimes a mass of blood vessels may be seen in the ear.

    The following tests may be performed to rule out other causes of dizziness.

    • CT scan
