Anatomical observations on the distal extremity of the vestibular aqueduct

A hitherto unobserved channel was observed, opening from the bony vestibular aqueduct under the dura. The location was in the centre between the contact of the aqueduct with the bulbar wall and the entrance of the aqueduct into the saccus. No connection was found between this formation and the vascular channels leading into the aqueduct or with the 'paravestibular canaliculus'. Albeit some of the examples were taken from Menière cases no interpretation in this direction was attempted. Strategical location claims further consideration as to morphology and function.
