OBJECTIVE Intraoperative far-field auditory brainstem response (ABR) and direct cochlear nerve action potential monitoring using neural response imaging (NRI) are techniques for monitoring the cochlear nerve during vestibular schwannoma (VS) surgery.

Cochlear nerve of the alligator lizard [PDF]
Journal of Comparative Neurology, 1985 AbstractThe innervation of the auditory organ of the alligator lizard is described. Patterns of distribution of the nerve fibers were studied at the light microscopic level with the horseradish peroxidase technique, and the types of synaptic contacts with hair cells were studied at the transmission electron microscopic level with standard techniques ...

The bony cochlear nerve canal in children with absent or hypoplastic cochlear nerves
International Journal of Pediatric Otorhinolaryngology, 2011To 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 ...

Effects of stimulation by cochlear implant on the cochlear nerve
The Laryngoscope, 1989AbstractDegeneration 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 Cochlear Nerve in Meniere's Disease
Archives of Otolaryngology - Head and Neck Surgery, 1980Cochlear nerves of 11 patients with advanced Meniere's disease were studied by light and electron microscopy. All the nerves appeared normal on light microscopy. In cross sections, the density of myelinated nerve fibers was approximately 20,000 fibers per square millimeter in most cases. In two cases, the density was reduced, about 14,000/sq mm.

Asymptomatic Schwannoma of the Cochlear Nerve
Archives of Otolaryngology - Head and Neck Surgery, 1982During systematic study of temporal bone histopathology at The Deafness Foundation, Memphis, we found an unsuspected small schwannoma arising solely from the cochlear nerve, compressing the facial nerve within the internal auditory canal. The primary temporal bone pathologic finding was bilateral otosclerosis.

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 ...

Cochlear Processes Reflected in Responses of the Cochlear Nerve
Acta Oto-Laryngologica, 1985The effects of sound frequency, intensity, and duration on responses of cochlear-nerve fibers and inner hair cells (IHCs) are reviewed and compared. The frequency selectivity observed in the nerve is already present in the IHC receptor potential but synaptic transmission appears to influence some other properties of the nerve response.

The involvement of the cochlear nerve in neurinomas of the eighth cranial nerve [PDF]
Archives of Oto-Rhino-Laryngology, 1989 In view of recent controversies concerning the preservation of hearing in acoustic neurinoma surgery, we examined the courses of the vestibular and cochlear nerve fibers in 12 intact acoustic neurinomas studied in our department. Due to its lack of specificity, the Luxol fast blue stain was found to be inadequate for our study of the nerve fibers.

Effect of Cochlear Nerve Electrocautery on the Adult Cochlear Nucleus
Otology & Neurotology, 2015Electrocauterization and subsequent transection of the cochlear nerve induce greater injury to the cochlear nucleus than sharp transection alone.Some studies show that neurofibromatosis Type 2 (NF2) patients fit with auditory brainstem implants (ABIs) fail to achieve speech perception abilities similar to ABI recipients without NF2.
