Summary
Cochlear implants (CI) benefit children with auditory neuropathy spectrum disorder (ANSD) as much as those with other forms of hearing loss. Speech development outcomes were comparable after one year of CI use in both groups.
Area of Science:
- Audiology
- Neuroscience
- Speech-Language Pathology
Background:
- Auditory neuropathy (AN) is a condition affecting speech discrimination, diagnosed by otoacoustic emissions and abnormal auditory evoked potentials.
- Treatment outcomes for speech perception in children with AN undergoing cochlear implant (CI) rehabilitation show variable results in existing literature.
Purpose of the Study:
- To compare the development of auditory and speech skills in children with auditory neuropathy spectrum disorder (ANSD) after cochlear implantation.
- To compare these outcomes against children with sensorineural hearing loss from other causes.
Main Methods:
- A systematic literature review and meta-analysis was conducted.
- Studies published between 1975 and 2023 were included, with 19 studies reviewed and 8 selected for meta-analysis.
Main Results:
- The meta-analysis found no significant difference in speech performance between children with ANSD and those with other causes of sensorineural hearing loss.
- This comparable outcome was observed one year after cochlear implant placement.
Conclusions:
- Cochlear implantation offers comparable benefits for speech development in children with ANSD versus children with other forms of neurosensory hearing loss.
- This suggests CI is an effective rehabilitation strategy for children with ANSD.
