[Physiological assessment of the rehabilitation of total deafness by the implantation of multiple intracochlear electrodes].
Cochelar implantation can only be entertained incases of complete endocochlear deafness and if the nerve fibres which transmit the auditory message to the cerebral centres are relatively unaffected. The electrodes should also be placed so as to follow roughly the spatial arrangement of the cochlear organ: each band of the speech area should have an electrode. It is however clear that a single electrode cannot offer selectivity as far as this spatial arrangement is concerned. The authors therefore decided to use 7 or 8 intra-cochlear electrodes. These were insulated from each other so as not to interfere with selective stimulation of the different groups of fibres.
