A Case Study of a 4-Year-Old Perilingual Deaf Child Implanted with an Ineraid Multichannel Cochlear Implant1

Abstract

In August 1989, we implanted the first young (age 2–4) perilingual deaf child with the Ineraidtm multichannel cochlear implant. The child experienced sudden deafness at the age of 3 years 9 months. The time lapse between the onset of deafness and the implantation of the electrode array was only 4 months, but during that time the child completely stopped talking. Electrically evoked auditory brainstem responses were used for diagnosis and follow-up.

Geneva Experience with the Ineraid Multichannel Cochlear Implant

“…This technique provides an objective assessment of auditory nerve activation by recording brainstem responses evoked by intracochlear electrical stimulation (electrically evoked auditory brain stem responses). The test is performed using light seda tion in children (ketamine) or local anesthesia in adults [ 12].…”
