Bilateral cochlear implantation is implantation on both sides, or the use of two cochlear implants. The advantages of hearing implants for the development of children with hearing loss have been demonstrated in numerous clinical studies.1,2,3
These studies show that some children receive unique benefits from bilateral cochlear implantation which may help them to develop listening skills, such as sound localization, during the critical period of language acquisition.
Many parents report that after receiving a second implant, their children are better able to concentrate in school. Still others report that their children are better able to localize sound, i.e. identify from where a sound originates. Clinical study results support these conclusions. For example, communication behavior was shown to improve among children who received a second implant. These children demonstrated better understanding of spoken words, and significantly better understanding of speech in noise when using both implants.4 Additionally, bilaterally implanted children have demonstrated better listening skills in challenging listening situations.5
