Human Cochlear Aqueduct and its Accessory Canals
Annals of Otology, Rhinology & Laryngology, 1977The anatomy of the adult human cochlear aqueduct and its surrounding structures, and their normal variations at tomography, microdissection and plastic molding are described. The mean length of the aqueduct is 12.9 mm and the mean width of its funnel-shaped external aperture 4.2 mm. The mean width of the narrowest portion is 0.14 mm.

Enlargement of the cochlear aqueduct is a controversial topic, with experienced investigators doubting its existence because of a lack of published cases. We describe the CT appearance of an enlarged cochlear aqueduct in a patient with advanced congenital inner ear anomalies and congenital hearing loss.

Cochlear Implantation With Large Vestibular Aqueduct Syndrome
The Laryngoscope, 2002AbstractObjectives In this investigation, we report the outcomes of 14 adults (age >18 y) and 9 children (age <18 y) with radiographically proven large vestibular aqueduct syndrome (LVAS) who received cochlear implants at Indiana University School of Medicine.Study Design This is a retrospective case‐control study detailing the outcomes of 23 ...

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 ...

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.

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 ...

Micro-CT study of the human cochlear aqueduct
Surgical and Radiologic Anatomy, 2018The anatomic structure of the cochlear aqueduct (CA) in human temporal bone specimens was observed using micro-computed tomography (CT).Micro-CT scanning of 18-µm-thick slices was performed on 30 slides of human temporal bone specimens to observe the CA structure and its relationship with its surroundings.

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.

Zhonghua er bi yan hou ke za zhi, 1991
The morphology and structure within the cochlear aqueduct have been investigated on the basis of a histological analysis of 234 temporal bones ranging from 12-week old to adult. Barrier membrane was found in 28.6% of the temporal bones examined, and fibrous reticular tissues of the inner opening of the cochlear aqueduct in 38.1% of the temporal bones ...
