title: Auditory perceptual abilities in a child with a nucleus and a Clarion cochlear implant.
abstract: This case study will review the performance of a 7-year-old female who was implanted at the age of 3 years 9 months with a Nucleus 22 channel device. This child was deafened from pneumococcal meningis at the age of 8 months and was placed in an early intervention program which uses simultaneous communication (i.e. speech with sign language). The teaching staff of this particular educational setting has collaborated closely with the Cochlear Implant Center at Manhattan Eye, Ear and Throat Hospital and the team's teacher of the deaf. The child utilized the implant on a daily basis for a period of 2 years 10 months. Performance on a variety of auditory perceptual tests were obtained at 1 year and two year intervals. After almost 3 years of implant use, the child suffered an internal receiver failure. The Nucleus device was explanted and the child was implanted with a Clarion Cochlear Implant System. Performance on a similar set of auditory perceptual tests obtained after 3 and 6 months use indicated better performance with the Clarion device. In addition to the scores on the individual tests, a comparison questionnaire was used to obtain impressions from the parents and the school personnel. Results should be reviewed with caution since this study investigates the responses of a single child who uses each of these two different implants and cannot be generalized.
