Structure

The labyrinthine artery is a branch of either the anterior inferior cerebellar artery (AICA) or the basilar artery.[1][2] It accompanies the vestibulocochlear nerve (CN VIII) through the internal acoustic meatus.[1] It divides into a cochlear branch and a labyrinthine (or anterior vestibular) branch.[1]

Function

The labyrinthine artery supplies blood to the inner ear.[1][3] It also supplies the vestibulocochlear nerve (CN VIII) along its length.[3]

Clinical significance

The labyrinthine artery may become occluded.[3] This can cause loss of hearing and balance on the affected side.[3]

History

The labyrinthine artery may also be known as the internal auditory artery or the auditory artery.
