Summary
Children born deaf (congenital deafness) and those who lost hearing before age 3 (prelingual deafness) show similar speech perception benefits from multichannel cochlear implants. Communication mode had minimal impact on their performance.
Area of Science:
- Audiology and Speech-Language Pathology
- Pediatric Otolaryngology
- Biomedical Engineering
Background:
- Cochlear implantation is a critical intervention for children with severe to profound hearing loss.
- Understanding the impact of age of deafness onset on speech perception outcomes is crucial for pediatric audiology.
- The role of communication modality in post-implantation speech development requires further investigation.
Purpose of the Study:
- To compare the speech perception abilities of children with congenital deafness versus those with prelingual deafness (onset before age 3) after receiving cochlear implants.
- To investigate the influence of communication mode (oral vs. total communication) on speech perception performance in prelingually deafened children with cochlear implants.
Main Methods:
- Nineteen children with prelingual deafness received Nucleus multichannel cochlear implants.
- Participants were categorized into two groups: congenital deafness (n=8) and deafness onset between birth and 3 years (n=11).
- Speech perception was assessed using 13 standardized tests, and performance was analyzed based on age of deafness onset and communication mode.
Main Results:
- No statistically significant differences in speech perception scores were found between the congenital deafness and prelingual deafness groups on 12 of 13 tests.
- Children using oral communication achieved significantly higher scores on only 2 of the 13 speech perception measures compared to those using total communication.
- Communication mode did not account for substantial variations in speech perception performance among prelingually deafened children with cochlear implants.
Conclusions:
- Children with congenital deafness demonstrate comparable potential for benefiting from multichannel cochlear implants as those with prelingual deafness.
- Early cochlear implantation offers significant speech perception benefits regardless of whether deafness was present from birth or occurred before age 3.
- The choice of communication modality appears to have a limited impact on the overall speech perception outcomes in this pediatric cochlear implant population.
