Isi artikel

In childhood, profound hearing loss (a hearing level of >90 dB) has far-reaching, lifelong consequences for children and their families. The most striking effect of profound hearing loss is the lack of development of spoken language, with its impact on daily communication; this, in turn, restricts learning and literacy,1 substantially compromising educational achievement and later employment opportunities.2,3 There is a high prevalence of psychosocial problems among deaf children.4 Fortunately, recent interdisciplinary developments are transforming outcomes, offering many more opportunities for deaf children. Recent advances5 suggest that deafness may be considered a model system for understanding neurosensory restoration. For example, cochlear implants can bypass the sensory end organ, stimulate the neurobiologic and neurocognitive substrates for speech and language processing, and consequently promote cognitive development. The children with the best results from cochlear implantation are among those who have received implants before 2 years of age. These children will enter first grade with expressive and receptive spoken language skills that are close to those of children with normal hearing6; their successful participation in mainstream education has become a realistic expectation.
