Thelabyrinthine artery (auditory artery,internal auditory artery) is a branch of either theanterior inferior cerebellar artery or thebasilar artery. It accompanies thevestibulocochlear nerve (CN VIII) through theinternal acoustic meatus. It supplies blood to theinternal ear.
The labyrinthine artery is a branch of either theanterior inferior cerebellar artery (AICA) or thebasilar artery.[1][2] It accompanies thevestibulocochlear nerve (CN VIII) through theinternal acoustic meatus.[1] It divides into a cochlear branch and a labyrinthine (or anterior vestibular) branch.[1]
The labyrinthine artery supplies blood to theinner ear.[1][3] It also supplies thevestibulocochlear nerve (CN VIII) along its length.[3]
The labyrinthine artery may become occluded.[3] This can cause loss ofhearing andbalance on the affected side.[3]
The labyrinthine artery may also be known as the internal auditory artery or the auditory artery.
