title: A young meningitically deaf child with a cochlear implant: a case study.
abstract: This study describes the development of the auditory, cognitive, linguistic, and social domains of a child deafened by meningitis at 20 months of age. He received a 3M/House cochlear implant at 27 months and is believed to be the youngest child to receive a cochlear implant. He was seen for intervention emphasizing audiometric conditioning and testing and language (speech and sign) stimulation for a period of 2:9 years (6 months pre-implant to 2:3 years post-implant). Videotapes of intervention; interviews with parents, teachers, and clinicians; test results; and medical and clinical reports were documented from pre-implant to two years post-implantation. The child regressed in all areas evaluated following his illness and subsequent deafness and cochlear implantation. At about one year after implantation, his social and cognitive skills began to improve. By two years after implantation (chronological age (CA) = 4:6), his abilities in all areas except auditory reception and speech had progressed to about the 4:0 age level. He communicates primarily through signs and seems to derive environmental sound and speech duration cues from the implant. Although it is difficult to separate the effects of the implant from maturational factors, he now willingly uses the implant simultaneously with his hearing aid on the non-implanted ear every day and seems to be functioning well with them. He responds inconsistently to his name when called, and consistently provides appropriate signed responses to questions. His imitative skills are improving; he can discriminate one- vs two-syllable words; and produces limited spontaneous speech. His cognitive and social abilities are at least age-appropriate and he signs 3- and 4-word combinations.
