Cochlear aqueduct

Dr Craig Hacking et al.

The cochlear aqueduct is a small narrow bony canal in the bony labyrinth of the petrous temporal bone. It contains the perilymphatic duct which arises from the scala tympani of the cochlea draining perilymph into the cerebrospinal fluid in the posterior cranial fossa near the lateral margin of the jugular foramen. It runs inferior and parallel to the internal auditory canal.
