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.{{Cite book|last1=Moini|first1=Jahangir|chapter-url=https://www.sciencedirect.com/science/article/pii/B9780128174241000124|title=Functional and Clinical Neuroanatomy - A Guide for Health Care Professionals|last2=Piran|first2=Pirouz|publisher=Academic Press|year=2020|isbn=978-0-12-817424-1|pages=363–392|language=en|chapter=12 - Auditory system|doi=10.1016/B978-0-12-817424-1.00012-4|s2cid=242466369 }}{{Cite book|last=Wilkinson|first=J.

It divides into a cochlear branch and a labyrinthine (or anterior vestibular) branch.
Function
The labyrinthine artery supplies blood to the inner ear.{{Cite book|last=Walker|first=M.|chapter-url=https://www.sciencedirect.com/science/article/pii/B9780123851574011854|title=Encyclopedia of the Neurological Sciences - Reference Module in Neuroscience and Biobehavioral Psychology|publisher=Academic Press|year=2014|isbn=978-0-12-385158-1|edition=2nd|pages=647–656|language=en|chapter=Vestibular System|doi=10.1016/B978-0-12-385157-4.01185-4}} It also supplies the vestibulocochlear nerve (CN VIII) along its length.
Clinical significance
History
The labyrinthine artery may also be known as the internal auditory artery or the auditory artery.
