    The last two decades have seen major advances in cochlear implants for profoundly deaf people. Implants are now used by severely to profoundly deaf adults and children in almost every phase of daily life. They have become an established treatment, and today's expectations for all aspects of the cochlear implant system are much greater than they were for the experimental devices of the early 1980s. Hardware designs have improved to meet clinical and research demands, technological developments have made the devices smaller and more reliable, and speech processing research has yielded a series of improvements in patient benefit.

    Comparison of current speech coding strategies
    Whitford, L. A. ; Seligman, P. M. ; Blamey, Peter J. ; McDermott, H. J. ; Patrick, J. F. ( 1993)
    This paper reports on two studies carried out at the University of Melbourne jointly with Cochlear Pty Ltd. The studies demonstrated substantial speech perception improvements over the current Multipeak strategy in background noise.

    Radiological evaluation of multiple-channel intracochlear implant insertion depth [Abstract]
    Marsh, Michael A. ; XU, JIN ; Xu, Shi-Ang ; Patrick, James F. ; Clark, Graeme M. ( 1993)
    Post-operative plain film x-rays are necessary in all multiple-channel cochlear implant patients to confirm intracochlear position of active electrodes, detect possible electrode kinking and provide a reference if post-operative slippage occurs. In addition precise documentation of multiple-channel intracochlear electrode insertion depths is necessary for comparison of speech recognition results between patients and may be of use for future speech processing strategies. In the present study a method has been devised using a modified Stenver's view to more accurately document insertion depths of the electrode array and location of individual electrodes on 50 multiple-channel cochlear implant patients. Surgical estimates of insertion depth are shown to have great variability in regard to distance along the basilar membrane when compared with x-ray documentation. The technique shows promise to facilitate mapping of binaural implant patients, young children, difficult adult cases, and possible new speech processing strategies as well as research activities requiring localization of individual electrodes.
