Origin
The vein of the vestibular aqueduct is formed by the union of venous tributaries draining the vestibule and semicircular canals of the internal ear (Standring, 2016).
Course
The vein of the vestibular aqueduct runs parallel to the vestibular aqueduct and the endolymphatic duct, prior to its opening into the inferior petrosal, sigmoid sinus, or the superior bulb of internal jugular vein.
Tributaries
The vein of the vestibular aqueduct receives the small veins draining the vestibule and the semicircular canals.
Structures Drained
The vein of the vestibular aqueduct drains blood from the vestibule and the semicircular canals.
