Labyrinthine artery explained

Labyrinthine artery
Latin:	arteria labyrinthi, arteria auditiva interna
Width:	250
Branchfrom:	Anterior inferior cerebellar artery or basilar artery
Vein:	Internal auditory veins
Supplies:	Inner ear

The labyrinthine artery (auditory artery, internal auditory artery) is a branch of either the anterior inferior cerebellar artery or the basilar artery. It accompanies the vestibulocochlear nerve (CN VIII) through the internal acoustic meatus. It supplies blood to the internal ear.

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. It divides into a cochlear branch and a labyrinthine (or anterior vestibular) branch.

Function

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

Clinical significance

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

History

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