Labyrinthine artery

The labyrinthine artery (auditory artery, internal auditory artery) is a branch of the anterior inferior cerebellar artery (85%-100% cases) or basilar artery (<15% cases). It accompanies the vestibulocochlear nerve through the internal acoustic meatus, and supplies blood to the internal ear.[1]
