What you can expect

During the procedure

The canalith repositioning procedure involves holding four positions for about 30 to 45 seconds each or as long as symptoms remain while you hold that position. Typically, you will remain in each position an extra 20 seconds after your symptoms have stopped. The procedure may be repeated three or more times within a treatment session.

Depending on your health provider’s preferences, you may wear an infrared imaging device over your eyes. This device helps your health provider examine your eyes during each maneuver. The device can help but it isn't necessary for successful treatment.

Here are the steps involved in the canalith repositioning procedure.

Step 1. First you move from a sitting to a reclining position with your head turned to the affected side by 45 degrees. Your health provider will help extend your head over the edge of the table at a slight angle.

Step 2. With your head still extended over the edge of the table, you'll be prompted to turn your head slowly away from the affected side by about 90 degrees.

Step 3. Roll onto your side. Your head should be slightly angled while you look down at the floor.

Step 4. Finally, you return carefully to a sitting position with your head tilted down and returned to the center position.

After the procedure

After the procedure, you'll need to keep the treated ear above the level of your shoulder for the rest of that day, so don't lie flat the rest of the day of treatment. At night, sleep on a slight incline with your head above your shoulders, using a few pillows. This lets the particles floating in your vestibular labyrinth settle into your utricle or be reabsorbed by your body fluids.

The next morning, following your doctor's instructions, you may need to perform similar exercises — but without hanging your head over the edge of the bed — by yourself to check whether the procedure in the office was effective. If your vertigo continues, tell your doctor. You may need to perform these exercises for several days before your symptoms subside.
