| This strategy for canalith repositioning moves otoliths around the circumference of the posterior semicircular canal in fewer steps than the CRP. An extreme head tilt is helpful in the first position to displace otoliths as far around the canal as possible. The patient is then rapidly moved to the second position. This rapid motion is essential to allow gravity in the second position to move the otoliths to the common crus before they start to fall back into the posterior canal. When the patient sits upright the otoliths move to the utricle and to the infundibulum of the posterior canal. Dark cells at these sites may facilitate resorption of otoliths. |
