360-Degree canalith repositioning procedure for the horizontal canal.
Otolaryngology - Head and Neck Surgery 2004 November
OBJECTIVES: To evaluate the efficacy of modifications to the standard canalith repositioning procedure (CRP) in the treatment of benign positional vertigo (BPV) of the horizontal semicircular canal (HSC).
STUDY DESIGN AND SETTING: Prospective trial of 72 patients with BPV of the HSC treated with a modified 360-degree CRP.
RESULTS: 51 of the 62 patients treated for canalolithiasis made a complete recovery (82.2%) after a single 360-degree CRP.
CONCLUSIONS AND SIGNIFICANCE: It is proposed a full 360-degree rotation of the HSC involved. It is essential to begin rotation of the patient departing from the affected side towards the healthy side, especially for canal side cupulolithiasis and for canalithiasis of the ampullar branch of the HSC. The head resting on the chest at angle of 30-degree during rotating encourages free-floating debris in the HSC to move into the utricle. Instead of using an oscillator for oscillation of the mastoid bone the head is shaken manually.
