Summary
Cochlear implants in children and adults yield similar speech perception scores. However, adults showed qualitative differences in perceiving specific speech sounds compared to children.
Area of Science:
- Audiology
- Speech-language pathology
- Neuroscience
Background:
- Cochlear implantation is a common treatment for deafness.
- Long-term outcomes in pediatric and adult cochlear implant users are of significant interest.
Purpose of the Study:
- To compare long-term speech perception results in prelingually deaf children and postlingually deafened adults after cochlear implantation.
- To identify similarities and differences in speech perception abilities between these two groups.
Main Methods:
- Retrospective analysis of long-term speech perception test results.
- Comparison of open-set scores and phonological contrast perception.
- Participants included prelingually deaf children and postlingually deafened adults who received cochlear implants at the same center.
Main Results:
- Average open-set speech perception scores were comparable between the pediatric and adult groups.
- Qualitative differences were observed in the perception of phonological contrasts between children and adults.
Conclusions:
- Cochlear implantation provides similar average speech perception benefits for long-term use in both prelingually deaf children and postlingually deafened adults.
- Subtle differences in phonological processing exist between these groups, warranting further investigation.
