Outcomes of cochlear implantation in deaf children of deaf parents: comparative study.

The Journal of laryngology and otology·2012

Cochlear implants benefit prelingually deaf individuals with additional disabilities, though autistic and deaf-blind patients show limited auditory progress. These specific groups require tailored rehabilitation for better outcomes.

Area of Science:

  • Audiology
  • Developmental Pediatrics
  • Neuroscience

Background:

  • Prelingually deaf individuals often receive cochlear implants (CIs) to restore hearing.
  • The presence of additional disabilities can impact CI outcomes.
  • Understanding the frequency and impact of comorbidities in this population is crucial for effective management.

Purpose of the Study:

  • To determine the prevalence of specific co-occurring conditions in prelingually deaf CI recipients.
  • To assess auditory perception development in CI users with these additional disabilities.

Main Methods:

  • Retrospective review of 398 prelingually deaf CI patients with at least one year post-implantation.
  • Identification of patients with developmental delays requiring psychological evaluation for co-occurring disabilities.

  • Comparison of auditory perception before and one year after CI surgery.

    • Main Results:

    • 15% (60/398) of patients had additional disabilities, including learning disability (33.3%), ADHD (25%), mild mental retardation (13.3%), moderate mental retardation (8.3%), cerebral palsy (8.3%), autism (6.7%), and congenital blindness (5%).
    • Significant speech perception gains were observed in most CI recipients.
    • Autistic and congenitally deaf-blind patients demonstrated limited auditory perception development.

    Conclusions:

    • Cochlear implantation is viable for prelingually deaf individuals with co-occurring conditions.
    • Congenitally deaf-blind and autistic patients experience restricted auditory development post-CI.
    • Specialized rehabilitation strategies are necessary to enhance auditory development in these specific patient groups.
