Figure 2 Common peripheral vestibular disorders Figure 2 | Common peripheral vestibular disorders. The figure shows the locations of common peripheral vestibular disorders that affect the vestibular nerve (left) or labyrinth (right). In multidisciplinary dizziness units, these disorders account for ∼45% of outpatient cases (Fig. 1). Typical vestibular nerve disorders include unilateral peripheral vestibulopathy (for example, vestibular neuritis or vestibular schwannoma), bilateral vestibulopathy, and vestibular paroxysmia caused by neurovascular cross-compression. Labyrinthine disorders include benign paroxysmal positional vertigo due to canalolithiasis of the posterior or horizontal semicircular canals, Ménière disease with endolymphatic hydrops, superior canal dehiscence syndrome due to a bony defect, and the rare labyrinthine ischaemia.
