Effect of age at cochlear implantation on auditory skill development in infants and toddlers.

OBJECTIVES: To investigate the effect of age at cochlear implantation on the auditory development of children younger than 3 years and to compare these children's auditory development with that of peers with normal hearing. DESIGN: Using a repeated-measures paradigm, auditory skill development was evaluated before and 3, 6, and 12 months after implantation. Data were compared with previously published data from cohorts with normal hearing. PARTICIPANTS: One hundred seven hearing-impaired children (age range, 12-36 months) who received a cochlear implant during clinical trials in North America. MAIN OUTCOME MEASURE: Auditory skill development was assessed using the Infant-Toddler Meaningful Auditory Integration Scale, a tool that provides a quantitative measure in children as young as newborns. RESULTS: Infants and toddlers who receive implants show rapid improvement in auditory skills during the first year of device use regardless of age at implantation, although younger children achieve higher scores. Children who undergo implantation at a younger age acquire auditory skills nearer to those of their peers with normal hearing at a younger age. The mean rate of acquisition of auditory skills is similar to that of infants and toddlers with normal hearing regardless of age at implantation. CONCLUSION: Performing implantation in children with profound hearing loss at the youngest age possible allows the best opportunity for them to acquire communication skills that approximate those of their peers with normal hearing.

Bilingual oral language proficiency in children with cochlear implants.

OBJECTIVE: To document oral language proficiency in a group of prelingually deaf bilingual children with a cochlear implant. DESIGN: Using a repeated-measures paradigm, oral language skills in the first and second language were evaluated at 2 yearly intervals after implantation. Language data were compared with normative data from children with normal hearing. SUBJECTS: Twelve deaf children between the ages of 20 months and 15 years who had received a cochlear implant before the age of 3 years. OUTCOME MEASURE: First-language skills were assessed using 1 of 2 standardized tests, either the Oral and Written Language Scales or the Reynell Developmental Language Scales, depending on the child's age. Second-language proficiency was assessed using the Student Oral Language Observation Matrix. RESULTS: Average standard scores in the first language fell solidly within the average range of normal-hearing peers. Second-language skills showed steady improvement from year 1 to year 2, along a continuum that reflected the amount and intensity of exposure of the child to the second language and the length of experience with the implant. CONCLUSION: A cochlear implant can make oral proficiency in more than 1 language possible for prelingually deaf children.

Second oral language capabilities in children with cochlear implants.

OBJECTIVE: The development of oral language in children with a cochlear implant is dependent on numerous factors. Although baseline achievements have been established, ceiling attainment levels have yet to be explored. One indicator of a higher capability level is the ability of children with implants to learn to communicate orally using a second language. The purpose of this research was to explore 1) the feasibility of children with cochlear implants developing oral fluency in a second language and 2) the factors that affect the development. STUDY DESIGN: Retrospective study of children fulfilling the criteria. SETTING: University medical center. PATIENTS: Eighteen profoundly hearing-impaired children who were reported to be bilingual. INTERVENTION: Cochlear implantation at age 5 or younger. MAIN OUTCOME MEASURES: The subjects were evaluated using standard speech perception and receptive and expressive language measures. RESULTS: The data revealed the ability of some pediatric cochlear implant recipients to develop competency in a second spoken language in addition to their primary language. Equally as important is the fact that the majority showed age-appropriate receptive and/or expressive language abilities in their primary language commensurate with normal-hearing children. CONCLUSION: High levels of achievement including the learning of a second spoken language are possible after implantation in the pediatric population. Variables include speech perception postimplantation, the linguistic environment, type of intervention, and educational placement.
