What does the caloric ear test show?

Caloric stimulation is a test that uses differences in temperature to diagnose damage to the acoustic nerve. This is the nerve that is involved in hearing and balance. The test also checks for damage to the brain stem.

How do you test for vestibular neuritis?

Tests to help determine if symptoms might be caused by vestibular neuritis include hearing tests, vestibular (balance) tests and a test to determine if a portion of the vestibulocochlear nerve has been damaged.

What is caloric labyrinthitis?

How can you tell the difference between BPPV and vestibular neuritis?

BPPV is a condition that causes small crystals to get loose and start to float in the fluid of your inner ear. The movement of the crystals and the fluid leads you to feel dizzy.

Does the Epley maneuver work for tinnitus?
