A Radiologico-Anatomical Comparative Study of the Cochlear Aqueduct [PDF]
Clinical Radiology, 2000 A comparative radiologico-anatomical study of the cochlear aqueduct (CA) was performed.Eight cadavers and 23 dry temporal bones were studied. High-resolution computed tomography (HRCT) was carried out on each cadaver before microdissection. Microdissection was carried out in a plane parallel to the HRCT sections.The CA was found to be located an ...

Radiology of the Cochlear Aqueduct
Annals of Otology, Rhinology and Laryngology, 2005Objectives: We sought to determine normative data for the radiologic presentation of the cochlear aqueduct (CA), hypothesizing that increasing the scanner's resolution could enhance detection capability. Methods: Axial sections of 502 ...

The cochlear aqueduct in pediatric temporal bones
European Archives of Oto-Rhino-Laryngology, 1997The cochlear aqueduct is a bony channel which contains the fibrous periotic duct and connects the perilymphatic space of the basal turn of the cochlea with the subarachnoid space of the posterior cranial cavity. Previous histological studies suggested that patency depended on age, whereas a more recent study showed no statistical correlation between ...

Cochlear Implantation: The Volumetric Measurement of Vestibular Aqueduct and Gusher Prediction [PDF]
Journal of Personalized Medicine, 2023 This study aimed to validate the role of 3D segmentation in measuring the volume of the vestibular aqueduct (VAD), and the inner ear, and to study the correlation between VAD volume and VAD linear measurements at the midpoint and operculum.

Cochlear implantation in Pendred syndrome and non-syndromic enlarged vestibular aqueduct – clinical challenges, surgical results, and complications [PDF]
Acta Oto-Laryngologica, 2016 OBJECTIVE: To explore specific clinical issues, surgical results, and complications of 80 cochlear implantations (CI) in 55 patients with Pendred syndrome (PS) or non-syndromic enlarged vestibular aqueduct (NSEVA).BACKGROUND: Previous studies have ...

Blockage of the Cochlear Aqueduct
Acta Oto-Laryngologica, 1974An experiment was performed on guinea pigs to determine whether blockage of their cochlear aqueducts would cause any morphological changes in their inner ears and, in particular, whether it would cause endolymphatic hydrops. In 17 animals in which the cochlear aqueducts were successfully blocked without injury to other structures, there were no ...

Patency of the Cochlear Aqueduct
Acta Radiologica. Diagnosis, 1985The patency of the cochlear aqueduct is discussed against the background of radioanatomic studies of 225 plastic casts of temporal bone specimens and additional experimental and clinical observations. The occasional presence of a wide venous channel running parallel with the cochlear aqueduct, as well as the existence of up to three accompanying venous

The cochlear aqueduct: Structural considerations
The Laryngoscope, 1979AbstractPerusing 170 series of temporal bone sections, the course of the aqueduct was found to be a spindle shape, based on numerous dilatations in the middle section. Ample space was offered for development of bony excrescences such as exostotic depositions and osteoma‐like protrusions of all sizes.
