Speech recognition performance of older children with cochlear implants

Area of Science:

• Audiology
• Pediatric Otolaryngology
• Speech-Language Pathology

Background:

• Previous studies indicated limited benefits of cochlear implants for prelingually deafened children implanted at older ages.
• Technological advancements and updated candidacy criteria may enhance cochlear implant viability for this demographic.

Purpose of the Study:

• To evaluate the efficacy of multichannel cochlear implants compared to conventional hearing aids in prelingually deafened children aged 5 years and older.
• To investigate whether oral communication users achieve better outcomes than total communication users post-cochlear implantation.

Main Methods:

• A repeated-measures design was employed to compare pre- and post-operative performance.
• Patients' performance with hearing aids was compared to their performance with the CLARION cochlear implant at 3 and 6 months.
• Outcomes were analyzed separately for children using oral versus total communication.

Main Results:

• Both oral and total communication groups showed significant improvements in all outcome measures after cochlear implantation.
• Children utilizing oral communication demonstrated significantly higher postoperative scores than those using total communication on four of five measures.

Conclusions:

• Prelingually deafened children aged 5+ experience substantial benefits from modern cochlear implants compared to hearing aids.
• Oral communication strategies yield the greatest benefits, while total communication shows more limited advantages in this population.
