The development of auditory perception in children following cochlear implantation

The time course for the development of auditory perception in prelingually deaf children following cochlear implantation may extend over many years, thus making long-term studies necessary to evaluate any such outcome. However, few such studies exist in the literature. We prospectively followed-up a consecutive group of 133 prelingually deaf children up to 6 years following implantation. All children were prelingually deaf with age at onset of deafness
