Cochlear Implantation in Children With Cochlear Nerve Absence or Deficiency
Otology & Neurotology, 2011To evaluate speech perception after cochlear implantation in children with cochlear nerve absence or deficiency.A retrospective case review was performed to identify children who underwent cochlear implantation with cochlear nerve absence or deficiency.

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.

Facial nerve stimulation in the narrow bony cochlear nerve canal after cochlear implantation
The Laryngoscope, 2015Objectives/HypothesisTo evaluate the correlation between a narrow bony cochlear nerve canal (BCNC) and facial nerve stimulation (FNS) after cochlear implantation (CI) and their underlying mechanisms and to predict the risk of FNS preoperatively.Study DesignRetrospective cohort study.MethodsA total of 64 pediatric cases that underwent CI were included ...

Degeneration behaviour of the cochlear nerve
Archiv f�r Klinische und Experimentelle Ohren- Nasen- und Kehlkopfheilkunde, 1971On 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

Cochlear Nerve Degeneration Coincident With Adrenocerebroleukodystrophy [PDF]
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.

Retrograde Degeneration of the Cochlear Nerve
Acta Oto-Laryngologica, 1975Retrograde 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.

Management of Cochlear Nerve Hypoplasia and Aplasia [PDF]
, 2018 Approximately 2% of congenital profound deafness cases are due to cochlear nerve (CN) deficiency. MRI is essential to confirm if the nerve is deficient, but because of limitations with resolution, especially when the internal auditory canal is narrowed, it is often unable to distinguish between hypoplasia and aplasia.

Cochlear nerve deficiency (CND) is defined as a small or absent cochlear nerve. It is most often diagnosed in the setting of congenital sensorineural hearing loss and represents around 1 % of cases within this population. It is associated with a recognized syndrome in 30–50 % of cases, most commonly CHARGE syndrome.

Facial nerve injury in cochlear implantation
Otolaryngology–Head and Neck Surgery, 1993We present eight cases of FN dysfunction after cochlear implantation. Four mechanisms of injury are proposed. The most common injury occurs from the heat of a bur shaft rotating over the FN in the facial recess. Several suggestions are made to help prevent the type of injuries we have seen.

Cochlear Nerve in Neurilemomas: Audiology and Histopathology
Archives of Otolaryngology - Head and Neck Surgery, 1978Correlative data between the histopathologic changes in the cochlear nerve and audiologic findings are reported in 16 cases of neurilemomas. Poor speech discrimination, positive or absent recruitment, excessive adaptation, or separation of forward vs reverse continuous tone Bekesy tracings did not correlate with the number of preserved nerve fibers ...
