Insights
Children with additional needs show reduced progress after cochlear implantation compared to peers without additional needs. While auditory perception may improve over time, language skills appear to plateau at lower levels, especially in those with multiple needs.
Area of Science:
- Otolaryngology
- Pediatric audiology
- Developmental pediatrics
Background:
- Cochlear implantation is a key treatment for severe to profound hearing loss.
- Children with additional needs have historically been excluded from cochlear implant candidacy.
- Recent years have seen increased inclusion of these children.
Purpose of the Study:
- To evaluate long-term outcomes of cochlear implantation in children with additional needs.
- To compare their progress against children without additional needs.
- To assess how trends change over time.
Main Methods:
- Longitudinal cohort study design.
- Comparison of three groups: no additional needs, single additional need, multiple additional needs.
- Assessment of auditory perception and language skills at pre-implant, 1, 3, and 5 years post-implant.
Main Results:
- Children with additional needs performed significantly poorer across all measures.
- Multiple additional needs correlated with a greater negative impact.
- Auditory perception improved over time in additional needs groups, but language skills plateaued at lower levels.
Conclusions:
- Additional needs significantly impact cochlear implant outcomes, with the number of needs being a critical factor.
- Auditory perception scores may improve, but language development shows limited long-term gains.
- Further research is needed to identify factors limiting outcomes and inform interventions.
Abstract:
Cochlear implant surgery is a cornerstone in the treatment of severe to profound hearing impairment. Despite comprising a significant proportion of the deaf population, children with additional needs have only been included for cochlear implant candidacy in recent years. This paper aims to evaluate the long-term progress of children with additional needs post-implantation compared to children without additional and assess how this trend changes over time.
Methods:
This is a longitudinal cohort study comparing the outcomes between children with no additional needs, children with a single additional need, and children with multiple additional needs. The five outcome measures used assessed both auditory perception and expressive and receptive language. For each outcome measure, subjects were assessed pre implant and one-, three-, and five-years post-implant.
Results:
The total cohort consisted of 334 subjects: 181 with no additional needs, 116 with a single additional need, and 37 with multiple additional needs. The results showed that children with additional needs performed significantly poorer in all outcome measures compared to those without additional needs, with a greater negative effect associated with multiple additional needs. In auditory perception, both additional needs groups increased in rate of progress over time, in contrast to language capabilities for which the rate plateaued at a significantly lower level than children without additional needs. Once again, both of these effects were greater for the multiple additional needs group.
Conclusion:
It is clear that there is reduced progress in children with additional needs compared to those without, and that the number of additional needs present is an important factor in this. Despite initial delays, it seems as though children with additional needs may catch up over time in auditory perception scores, however for language skills, this cohort may achieve limited scores even as time progresses. It is important to investigate this further to gauge the factors that are causing this discrepancy to see if any can be limited to maximise outcome.
