Explanation of the Post

Through the following articles we can confirm that cochlear implantation offers improvements in children in terms of auditory neuropathy (AN) versus cochlear nerve deficiency (CND). It has been found that children with auditory neuropathy have achieved improvements in speech perception, while children with cochlear nerve deficiency failed to experience any increase.

When seeing the success with the cochlear implant with children with auditory neuropathy, it was decided to carry out another study to see if the implant improved with children who had both deficiencies, but this study proved that presenting both deficiencies no favorable result was obtained.

Thus, with the cochlear implant there are significant improvements in the majority of children with auditory neuropathy in the following parameters: auditory perception being more stable, improvement in auditory discrimination, increase in the development of expressive and comprehension language and good auditory feedback, among others.

In conclusion, some children with AN can benefit significantly from cochlear implants while children with CND have more difficulties due to lack of neural synchronization and other associated conditions.
