Asymptomatic Schwannoma of the Cochlear Nerve

Archives of Otolaryngology - Head and Neck Surgery, 1982
During 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.

Unilateral Cochlear Nerve Deficiency in Children

Otolaryngology–Head and Neck Surgery, 2013
ObjectiveCochlear nerve deficiency (CND) is increasingly diagnosed in children with sensorineural hearing loss (SNHL). We sought to determine the prevalence of CND, its imaging characteristics, and correlations with audiologic phenotype in children with unilateral SNHL.DesignCase series with chart review.SettingTertiary pediatric hospital.Subjects ...

Cochlear Processes Reflected in Responses of the Cochlear Nerve

Acta Oto-Laryngologica, 1985
The 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 management of cochlear nerve deficiency

Cochlear Implants International, 2013
The assessment process is critical in deciding whether a profoundly deaf child with cochlear nerve deficiency (CND) will be suitable for a cochlear or auditory brainstem implant (ABI). Magnetic resonance imaging (MRI) using submillimetric T2 weighted gradient echo or turbo spin echo sequences is mandatory for all profoundly deaf children to diagnose ...

Cochlear Nerve Degeneration Coincident With Adrenocerebroleukodystrophy

Archives of Otolaryngology - Head and Neck Surgery, 1976
A 19-month-old boy had adrenocerebroleukodystrophy and unusually severe cochlear nerve degeneration and demyelination, a condition in advance of that expected from known disease entities. We report the only known temporal bone study in adrenocerebroleukodystrophy.

Cochlear nerve of the alligator lizard

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 ...

Degeneration behaviour of the cochlear nerve

Archiv f�r Klinische und Experimentelle Ohren- Nasen- und Kehlkopfheilkunde, 1971
On the basis of the degeneration behaviour two different types of cochlear afferent neurons can be distinguished. About 95% of all cochlear neurons are of the common type I with large myelinated spiral ganglion cells. They show complete retrograde degeneration after transsection of the cochlear nerve and they are exclusively connected to the inner hair

Retrograde Degeneration of the Cochlear Nerve

Acta Oto-Laryngologica, 1975
Retrograde degeneration of the cochlear neurons has been studied in different types and degrees of peripheral cochlear damage such as acoustic trauma, intoxication, heredodegenerative deafness and others. It starts only when the peripheral dendrites to the inner hair cells are irreversibly damaged.

The Vestibulocochlear Nerve: Cochlear Branch Or Nerve

1995
Abstract The cochlear nerve, which is also referred to as the cochlear branch of the acoustic or vestibulocochlear nerve, is sensory in nature, and its peripheral processes are distributed within the cochlea-the organ responsible for analyzing sound; thus, it is the nerve specifically concerned with audition. Spiral or Cochlear Ganglion.

Unilateral cochlear hypoplasia and cochlear nerve aplasia

Clinical History: A sixteen-year-old male patient presented with congenital deafness on the left side and normal hearing on the right side. There was a family history of deafness and hearing loss on the father’s side. He experienced relatively few difficulties in daily life.
