Abstract
- Multicanal BPPV (benign paroxysmal positional vertigo), especially BPPV affecting both labyrinths, is uncommon. A review of the literature revealed that the majority of reported cases of multiple BPPV either involved a combination of two different canals limited to one labyrinth or two different canals in both labyrinths, although one case of multicanal BPPV was reported to involve three canals bilaterally. Here, the authors report a case of bilateral posterior canalolithiasis and unilateral horizontal canal cupulolithiasis in a 54-year-old man, and include a review of the literature.
