STRUCTURE AND FUNCTION OF THE COCHLEAR AQUEDUCT
Archives of Otolaryngology - Head and Neck Surgery, 1952THE COMMONLY accepted view about the cochlear aqueduct is that it provides an open connection between the perilymphatic space of the cochlea and the subarachnoid space of the brain. It is often said also that perilymph is simply cerebrospinal fluid. Yet there is clinical evidence that is difficult to reconcile with such views.

Functional Patency of the Cochlear Aqueduct
Annals of Otology, Rhinology & Laryngology, 1982The perilymphatic (P P ) and cerebrospinal fluid (P CSF ) pressures were investigated in relation to pressure variations in the ear canal, middle ear and intracranial compartment before and after occlusion of the cochlear aqueduct (CA).

In six infant ears the cochlear aqueduct had an average length of 3.5 mm while that of adults was earlier found to measure 6.2 mm. The width of the aqueduct was relatively large being at least 150 μm at the narrowest point, 0.5–1 mm from scala tympani.

Petromastoid canal and cochlear aqueduct in cochlear implant candidates
Otolaryngology–Head and Neck Surgery, 2009ObjectiveTo present temporal bone fine channels in cochlear implantation candidates.MethodsReview of the axial sections of 108 temporal bone CTs. In type I, the petromastoid canal (PMC) was invisible but appeared as channels in type II and type III, <0.5 and 0.5‐1 mm wide, respectively, and in type IV was >1 mm wide.

Enlargement of the cochlear aqueduct: Fact or fiction?
Otolaryngology–Head and Neck Surgery, 1993Enlargement of the cochlear aqueduct (CA) is often mentioned in the otologic literature, usually in its purported association with sensory hearing loss, stapes gusher, and transotic cerebrospinal fluid leak. In CT scans of 100 ears, the diameter of the CA medial aperture was found to be highly variable, ranging from 0 to 11 mm, with a mean of 4.5 mm ...

IT IS generally assumed that the cochlear aqueduct is a canal through which spinal fluid flows from the subarachnoid spaces to the scala tympani of the cochlea. This theory of the physiology of the cochlear aqueduct is based entirely on histopathologic observations.

Studies on Cochlear Aqueduct Patency
Annals of Otology, Rhinology & Laryngology, 1978Complex studies on the patency of the cochlear aqueduct were made on 250 human cadavers and the temporal bones isolated from these, using a chemical method (staining reaction) as well as filling the aqueduct with fluid plastics and exposing the whole of its course under an operating microscope. The disappearance of patency in the cochlear aqueduct is a

AbstractMultidirectional tomography (MDT) can be useful in determining the caliber, shape, and course of the vestibular aqueduct (VA) and cochlear aqueduct (CA). Clinical decisions have been based on the findings from MDT. Unfortunately, the clinical utility of these observations has been confusing and controversial because similar MDT techniques were ...

The cochlear aqueduct is a fine duct connecting the scala tympani with the subarachnoid space. Intraductal space is occupied by mesh-like connective tissue. The internal aperture which has a separating membrane opens at the inner ridge of the round window.

To the Editor .—Dr. Palva comments that an increased perilymphatic pressure would be more likely to cause compression of the endolymphatic system. This would certainly seem to be true provided the endolymphatic system itself were a normal one. In this case, however, the increased perilymphatic pressure occurred in the presence of an already existing ...
