vestibular aqueduct

The vestibular aqueduct is a structure of the inner ear being part of the osseous labyrinth. It contains the endolymphatic duct and sac. It normally has a diameter of approximately 1.5 mm (similar to the posterior semicircular canal) and runs from the vestibule in a transverse direction to the long axis of the petrous temporal bone to the posterior cranial fossa.
