Area of Science:

  • Audiology and Speech-Language Pathology
  • Pediatric Neurodevelopmental Disabilities
  • Biomedical Engineering

Background:

  • Bilateral prelingual sensorineural hearing loss affects 15-30% of individuals with associated disabilities.
  • Cochlear implantation (CI) offers access to auditory and speech information, enhancing quality of life and development.
  • Limited research exists on long-term CI outcomes in children with co-occurring neurodevelopmental delays.

Purpose of the Study:

  • To evaluate the long-term auditory and communicative performance of children with CI and delayed neuropsychomotor development.
  • To assess changes in auditory thresholds, speech perception, and language skills after at least five years of CI use.
  • To explore parental perceptions of their child's functional and social development with CI.

Main Methods:

  • Retrospective study of eight pediatric patients with CI and delayed neuropsychomotor development.
  • Analysis of multidisciplinary clinical records and remote questionnaire data.
  • Utilized tools: Children with Cochlear Implants: Parental Perspectives (CCIPP), ICF-CY, and GMFCS.

Main Results:

  • Significant improvements observed in auditory thresholds across all frequencies and speech detection thresholds over time.
  • Demonstrated notable advancements in language and overall hearing outcomes with continued CI use.
  • Parental feedback indicated positive perceptions of social development but expressed concerns regarding educational progress.

Conclusions:

  • Cochlear implantation facilitates significant auditory and language skill progression in children with associated disabilities.
  • The benefits of CI are evident even with co-occurring neurodevelopmental challenges.
  • Further multicenter research with larger cohorts is recommended to optimize rehabilitation strategies for this population.
