360-Degree Canalith Repositioning Procedure for the Horizontal Canal

abstract

The 360-degree procedure is a variant of the repositioning practice that we usually perform in the treatment of benign positional vertigo (BPV) of the horizontal semicircular canal (HSC). This procedure, developed in 7 positions, involves the patient’s rotation by 360-degrees along his long...

itudinal axis. It is important to begin patient’s rotation starting from the affected side towards the healthy side. In order to move into the utricle, the resting head on the chest at angle of 30-degree during rotating encourages free-floating debris in the HSC. The head is shaken manually for the oscillation of the mastoid bone. To evaluate the efficacy of this manoeuvre we have studied, in a prospective trial, 72 patients with typical BPV of the HSC treated with a modified 360-degree CRP. 51 of the 62 patients treated for canalolithiasis progressed with a complete recovery (82.2%) after a single 360-degree CRP. This treatment facilitates therapists’ job and reduce the persistence of dizziness after the healing.
