Vestibular aqueduct

Aqueductus [Aquae-] vestibuli

  • Latin synonym: Canaliculus vestibuli
  • Synonym: Vestibular canaliculus

Definition

The vestibular aqueduct is a narrow bony canal which emerges from the bony vestibule and traverses backwards through the temporal bone to open up onto the posterior surface of the petrous part of the temporal bone, into the posterior cranial fossa

It contains the endolymphatic duct and sac.

Note: the term vestibular canaliculus is preferred term when the morphology of the temporal bone is considered; the term vestibular aqueduct is used when the internal ear is the focus of study.
