Definitions for "Canalithiasis"
the theory of BPPV, where free-floating debris can migrate into a semicircular canal and cause short episodes of vertigo when it moves within the canal.
A condition in which loose densities in a semicircular canal produce nystagmus and vertigo when a critical provocative position of the head is assumed. The symptoms generated are called benign paroxysmal positional vertigo (BPPV).
