Residual Dizziness after Benign Paroxysmal Positional Vertigo / 대한이비인후과학회지

ABSTRACT

Benign paroxysmal positional vertigo (BPPV) is one of the most common diseases that cause dizziness. It can be resolved relatively easily using canalith-repositioning maneuvers. However, some patients suffer from dizziness even after successful canalith-repositioning. This is an atypical dizziness felt in the absence of typical nystagmus after resolution of BPPV and named residual dizziness. Otolithic organ disorder, anxiety and persistence of debris in the canal have been reported to be associated with residual dizziness. Although 31-61% of BPPV patients suffer from residual dizziness, residual dizziness has not yet been clearly known not only the treatment but also the pathophysiology. This article investigate the factors associated with residual dizziness and treatment and prediction methods for residual dizziness.
