Abstract
|
|
|
|
Canal paresis in patients with benign paroxysmal positional vertigo (BPPV) has been variously reported from 26 to 50%. In such cases, BPPVs are developed secondary to accompanying vestibulopathy or other underlying inner ear diseases. Also the side of canal paresis is regarded as involved ear in the lateralization of horizontal canal BPPV (HC-BPPV), in which lateralization is sometimes ambiguous just by Eward’s second law. In this case, authors report a woman who had HC-BPPV and pathologic canal paresis which resolved after canalith repositioning. This case may imply that dislodged particles block the endolymphatic flow resulting canal paresis.
