The canalith repositioning procedure can help relieve benign paroxysmal positional vertigo (BPPV). BPPV is a condition that causes brief, but intense, feelings of dizziness and spinning. These sensations also are known as vertigo. They may occur when you move your head.
Vertigo usually comes from a problem with the part of the inner ear responsible for balance. BPPV occurs when tiny canalith particles, also called otoconia, in one part of the inner ear break loose and fall out of place. They often move into the semicircular canals of the inner ear. This can make you sensitive to movement and cause vertigo.
The canalith repositioning procedure can move these particles to a part of the ear where they won't cause dizziness. The procedure uses several simple head movements. It can be done in a health care provider's office. The procedure is usually effective. The procedure relieves vertigo in about 80% of people after one or two treatments. But the problem may happen again.
The canalith repositioning procedure is done to relieve symptoms of BPPV. The procedure moves the particles causing symptoms from a sensitive part of the ear — called the semicircular canals of the inner ear — to an area where they won't cause problems, called the utricle. Once there, these particles won't cause vertigo. The particles will likely dissolve or be reabsorbed by the body.
The canalith repositioning procedure has certain risks, such as:
Make sure you tell your health care provider about any medical conditions you have, such as a neck condition, a back condition or advanced rheumatoid arthritis, before getting the procedure. You may need to delay having the procedure.
There are no special preparations for the canalith repositioning procedure. Wear clothing that will allow you to move freely through each position.
The canalith repositioning procedure involves holding four positions for about 30 seconds each or until symptoms stop. You'll stay in each position about 30 seconds after your symptoms have ended. Your health care provider will watch your eyes for irregular movements during the procedure. The procedure may be repeated three or more times within a treatment session.
The canalith repositioning procedure includes these steps:
After the procedure, follow your health care provider's instructions. Your care provider may teach you how to do the procedure so that you can do it at home if needed. You may need to do these exercises for many days before your symptoms go away.
Nearly 80% of people who have the procedure experience relief. But if your symptoms come back, your health care provider can repeat the canalith repositioning procedure. The procedure may need to be done many times to help your symptoms. Talk to your health care provider if your symptoms don't improve.
