ABSTRACT
The recording of auditory brain stem potentials evoked by electrical stimulation of the cochlea is a part of our assessment protocol before pediatric cochlear implantation. It constitutes an objective and reproducible method to estimate the stimulability of the auditory system for candidates to cochlear implant. Ten children, aged from 3 to 12 years, with deep deafness of the 2nd and 3rd group with no response to ABR, undergone electric stimulation of the cochlea. All patients were anesthetized and paralyzed. Electric pulses are delivered by a cochlear stimulator, through a transtympanic needle electrode, placed in the promontory. We record responses on a Medelec "Saphire" computer. One of the main problem we try to solve is the stimulus artefact which occurs during the first ms. The other one is to be sure that the recorded responses are corresponding to the neural activity of the auditory nerve and the brainstem auditory pathway.
