Benign Paroxysmal Positional Vertigo
Vertigo is a feeling of movement or spinning when you are still. Benign paroxysmal positional vertigo (BPPV) happens when the vertigo is caused by changes your head's position. This might include standing after bending down, turning your head in bed or extending your neck to look up.
Causes of BPPV
The inner ear contains tiny crystals that can sense movement and help you keep your balance. BPPV occurs because of a shift in location of these crystals or the clumping of these crystals. When this happens, your brain gets signals that you're moving when you're now. This causes the feeling of movement.
The clump of ear crystals can lead to BPPV.

In some cases, the cause of BPPV is unknown. In others, it may be caused by:
- Head injury
- Viral infection
- Disorders of the inner ear
- Prolonged immobility of the head
- Age-related changes to inner ear
Symptoms of BPPV
Symptoms may include:
- Sensation of spinning or rotation when you change head position that lasts less than one minute
- Loss of balance
- Ringing or buzzing sounds in the ear
- Vision or hearing problems
Your doctor may recommend tests to help determine the cause of vertigo symptoms, including:
- Dix-Hallpike maneuver — moving your head or body in certain ways to test response
- MRI scan
- Electronystagmography (ENG)
Many times BPPV can resolve on its own, usually within months of onset. Talk with your doctor about the best treatment plan for you.
Your doctor may suggest specific vestibular exercises. These exercises use a series of eye, head and body movements to get the body used to moving without dizziness. You may work with a physical therapist to learn these.
Your doctor will move your head in different positions to try to resettle the tiny crystals. The procedure is sometimes repeated and you may be taught how to do it at home.
During surgery, your doctor may use a piece of wax to plug one area of your ear. This prevents fluid in your inner ear from moving. Another type of surgery involves cutting the nerve from the inner ear.
