Findings from four studies indicated improved speech perception post-cochlear implantation as compared to hearing aids, both for open-set word and sentence perception scores. Two studies investigated auditory performance and both found improvements post-cochlear implantation as compared to hearing aids. Results were inconclusive regarding the impact of cochlear implantation on speech intelligibility. One study investigated social-emotional functioning; there was no statistical difference between scores for children who used cochlear implants versus hearing aids. Two studies reported risks of losing residual hearing following cochlear implantation. Other negative outcomes included discontinued use of cochlear implants (5.3% of children) or intermittent/non-use of hearing aids in the non-implanted ear for 8.8% of children with bimodal devices.
