Clinical utility of cervical vestibular-evoked myogenic potentials in predicting residual dizziness after benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV) is one of the most common vestibular disorders with a lifetime prevalence of approximately 2.4% in the general population (von Brevern et al., 2007). Otoconial particles, which have fallen from otolith organs into semicircular canals, induce BPPV (Bhattacharyya et al., 2008). BPPV can be cured through appropriate canalith repositioning maneuvers (Fife et al., 2008; Helminski et al., 2010). However, despite clear pathogenesis and treatment, some patients still experience an imbalance after successful repositioning maneuvers.
