Cochlear Implantation in Children With Cochlear Nerve Deficiency

International Journal of Pediatric Otorhinolaryngology, 2014
The aim of this study was to report on auditory performance after cochlear implantation in children with cochlear nerve deficiency.A retrospective case review was performed. Five patients with pre-lingual profound sensorineural hearing loss implanted in an ear with cochlear nerve deficiency participated in the study.

CT and MR Imaging for Pediatric Cochlear Implantation: Emphasis on the Relationship Between the Cochlear Nerve Canal and the Cochlear Nerve

Pediatric Radiology, 2010
Cochlear implantation has become an accepted treatment for deafness. As the frequency of cochlear implantation has increased, requests for images have also increased in the work-up for candidates. An absent cochlear nerve (CN) is a contraindication to cochlear implantation.

Bony Cochlear Nerve Canal and Internal Auditory Canal Measures Predict Cochlear Nerve Status

open access: yesJournal of Laryngology and Otology, 2017
Objectives:The bony cochlear nerve canal is the space between the fundus of the internal auditory canal and the base of the cochlear modiolus that carries cochlear nerve fibres.

Connections Between the Facial, Vestibular and Cochlear Nerve Bundles Within the Internal Auditory Canal

open access: yesJournal of Anatomy, 2004
The vestibular, cochlear and facial nerves have a common course in the internal auditory canal (IAC). In this study we investigated the average number of nerve fibres, the average cross-sectional areas of the nerves and nerve fibres, and the apparent ...

Effects of stimulation by cochlear implant on the cochlear nerve

The Laryngoscope, 1989
AbstractDegeneration of the cochlear nerve before and after placement of the cochlear implant might influence the efficacy of the device. We examined histological characteristics, including the caliber of the cochlear nerve fibers of the central segment proximal to the porus acusticus, in three profoundly deaf patients.

The bony cochlear nerve canal in children with absent or hypoplastic cochlear nerves

International Journal of Pediatric Otorhinolaryngology, 2011
To correlate presence and size of the bony cochlear nerve canal [BCNC] with size of the internal auditory meatus [IAM] on CT in children with absent or hypoplastic cochlear nerves [CNs] as compared to age matched controls.This retrospective case-notes review was based in the departments of Cochlear Implantation and Neuroradiology at a tertiary ...

Cochlear or Nerve Stimulation

Pacing and Clinical Electrophysiology, 1987
To simulate through electrical stimulation the auditory nerve excitation patterns produced by a normal ear, it is necessary to control both the spatial and the timing aspects of the neural firing pattern. While the spatiaJ localization, the “place” aspect of stimulation can probably be achieved adequately with either scala tympani or direct eighth ...
