Management of Cochlear Nerve Hypoplasia and Aplasia [PDF]

open access: possibleAdvances in Oto-Rhino-Laryngology, 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.

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 Deficiency

2016
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.
