Summary

Cochlear implantation (CI) can significantly improve hearing and speech perception in prelingually deafened adults who received early auditory-verbal/oral communication training. These individuals can achieve good outcomes and integrate well into society.

Area of Science:

  • Audiology
  • Otolaryngology
  • Speech and Hearing Sciences

Background:

  • Prelingually deafened adults often face challenges with spoken language and hearing.
  • Auditory-verbal/oral communication training from childhood aims to develop listening and speaking skills.
  • The effectiveness of cochlear implantation (CI) in this specific population requires careful evaluation.

Purpose of the Study:

  • To assess the efficacy of cochlear implantation (CI) in prelingually deafened adults.
  • To determine if prior auditory-verbal/oral communication training influences CI outcomes.
  • To evaluate hearing thresholds and speech perception improvements post-CI.

Main Methods:

  • Retrospective analysis of eight prelingually deafened adults with severe to profound sensorineural hearing loss.

Cochlear Implant Surgery and Electrically-evoked Auditory Brainstem Response Recordings in C57BL/6 Mice

Published on: January 9, 2019

  • All participants used hearing aids (HA) before age two and received auditory-verbal/oral training.
  • Data collected included preoperative/postoperative hearing levels, speech perception scores, and rehabilitation history.

    • Main Results:

    • Significant improvements in pure-tone hearing thresholds were observed post-CI.
    • Speech perception, measured by the Japanese video speech discrimination score (SDS), also showed marked improvement.
    • All patients successfully integrated CI into their daily lives, actively participating in society.

    Conclusions:

    • Cochlear implantation (CI) can yield considerable benefits for prelingually deafened adults with a history of auditory-verbal/oral training.
    • CI candidacy for prelingually deafened adults should be carefully considered, not automatically excluded.
    • Successful outcomes are associated with consistent auditory-verbal/oral habilitation and well-fitted hearing aids prior to implantation.
