Abstract

|
Although vestibular neuritis is defined as acute peripheral vestibulopathy without associated hearing loss, a handful of cases reported sudden hearing loss without concurrent vertigo during follow-up of vestibular neuritis. In addition, some patients show benign paroxysmal postional vertigo(BPPV) ipsilateral to the lesion side with various interval after vestibular neuritis, and they are considered to be "secondary" BPPV. Viral and vascular etiologies have been assumed for the vestibular neuritis but, both of those failed to explain exact pathomechanism so far. Authors experienced a case of sudden hearing loss with simultaneous ipsilateral BPPV after vestibular neuritis. There has been no report of concurrent of BPPV and sudden hearing loss after vestibular neuritis. Sequential viral activations are considered to be responsible for this case.
