Veins of labyrinth
The veins of the labyrinth (also internal auditory veins, Latin: venae labyrinthi) are venous blood vessels that accompany the labyrinthine artery and drain the inner ear.
These veins arise from the union of veins of the vestibule and semicircular canals at the base of the modiolus of the inner ear. Further, the veins of the labyrinth pass through the internal acoustic meatus and empty into the posterior part of the superior petrosal sinus or in the inferior petrosal sinus.
The veins of the labyrinth collect venous blood from structures of the internal ear.
