Auditory dysfunction

Abstract

Hearing impairment, although uncommon, may occur in patients with a vertebrobasilar artery occlusion disease. The pathogenesis may be an ischemic lesion involving the auditory pathways in the pons and midbrain, the cochlear nucleus, cochlear nerve or the cochlea. The AICA and IAA are the main arteries that supply the peripheral audiovestibular structures of the inner ear and central audiovestibular pathways of the middle cerebellar peduncle and lateral pons.
