Insights

Children with auditory neuropathy (AN)/auditory dyssynchrony (AD) showed improved speech perception with hearing aids or cochlear implants. However, outcomes were less favorable compared to children with sensorineural hearing loss.

Area of Science:

  • Audiology
  • Neuroscience
  • Speech-Language Pathology

Background:

  • Auditory neuropathy (AN)/auditory dyssynchrony (AD) is a complex hearing disorder affecting the auditory nerve.
  • Management of AN/AD often involves hearing aids or cochlear implants, but outcomes can vary.

Purpose of the Study:

  • To compare speech perception in children with AN/AD treated with hearing aids versus cochlear implants.
  • To evaluate the effectiveness of auditory rehabilitation in children with AN/AD.

Main Methods:

  • Prospective study comparing three groups: AN/AD with hearing aids, AN/AD with cochlear implants, and sensorineural hearing loss with cochlear implants.
  • Speech perception assessed using open-set monosyllabic word recognition (consonant-nucleus-consonant).

Main Results:

  • 90% of implanted AN/AD children achieved significant speech discrimination (CNC score >= 55%).
  • Aided AN/AD children demonstrated similar speech perception results.
  • Both AN/AD groups performed less well than the control group with sensorineural hearing loss.

Conclusions:

  • Cochlear implantation can provide functional hearing for children with AN/AD.
  • Outcomes for AN/AD patients may require adjusted expectations compared to those with peripheral hearing loss.
