Disorders affecting the peripheral vestibular system commonly involve the peripheral auditory system causing hearing loss. There are a number of disorders, however, that selectively involve the peripheral vestibular system causing dizziness without hearing loss. These disorders include benign paroxysmal positional vertigo, vestibular neuritis, recurrent vestibulopathy, familial vestibulopathy, and bilateral idiopathic vestibulopathy. This article reviews these disorders and their diagnosis and management.
