This study shows that children with prelingual deafness who received cochlear implants demonstrated significant speech perception improvements over 3 years. Cochlear implantation enhances auditory skills in deaf children.

Area of Science:

  • Audiology
  • Pediatric Medicine
  • Neurosurgery

Background:

  • Prelingual deafness significantly impacts speech development.
  • Cochlear implantation is a key intervention for profound hearing loss.
  • Assessing speech perception is crucial for evaluating cochlear implant efficacy.

Purpose of the Study:

  • To evaluate speech perception outcomes in prelingually deaf children with Combi 40/40+ cochlear implants.
  • To track performance improvements over a 3-year period post-implantation.
  • To analyze results from the Evaluation of Auditory Responses to Speech (EARS) test battery.

Main Methods:

  • A cohort of 31 prelingually deaf children was studied.
  • The Evaluation of Auditory Responses to Speech (EARS) test battery was administered.

  • Speech perception was assessed using closed-set and open-set tests over 36 months.

    • Main Results:

    • Consistent improvement was observed across all EARS test measures up to 3 years post-implantation.
    • Listening Progress Profile (LiP) scores increased from 4% preoperatively to 93% at 36 months.
    • Open-set speech perception scores reached up to 100% in some children by the 36-month evaluation.

    Conclusions:

    • Congenitally and prelingually deaf children show continuous speech perception gains after cochlear implantation.
    • Cochlear implantation effectively improves both closed-set and open-set speech perception.
    • Individual performance variability exists, highlighting the need for personalized rehabilitation strategies.
