    Initial results for six patients with a multiple-channel cochlear prosthesis
    Dowell, R. C. ; Brown, A. M. ; Seligman, P. M. ; Clark, Graeme M. (Monash University Press, 1983)
    A total of eight patients have been assessed with the multi-channel cochlear prosthesis at the University of Melbourne. The first two patients were implanted with a prototype device in 1978 and 1979, and their results with various speech evaluation procedures have been reported and summarized in detail elsewhere (Clark & Tong, 1982). Briefly, these results indicated that some very significant benefit could be obtained for these patients when using the cochlear prosthesis with external speech processing, particularly when using the device in conjunction with lipreading. It was also shown that some significant understanding of speech was possible without lipreading (open-set) for both patients, although this was fairly limited.

    Advances with the 22-channel cochlear implant
    Hirshorn, Michael S. ; Clark, Graeme M. ; Mecklenburg, Dianne J. (Kugler & Ghedini, 1988)
    The Nucleus 22 Channel Cochlear Implant was developed on the basis of work at the University of Melbourne. Between 1967 and 1978, there was extensive research with animals and human temporal bones, especially regarding safety, psychophysics, histopathology and surgical approaches. As a result of this work, it was decided to develop a multi-channel intracochlear implant. The 22 channel implant has been used in more than 500 patients world-wide but there were many steps on the road to this success. Today, over one third of the post-lingually profound, deaf adults implanted with this device have significant speech understanding without lipreading.

    Surgery for multielectrode cochlear implants
    Lehnhardt, E. ; Laszig, R. ; Webb, H. ; Franz, B. ; Pyman, B. ; Clark, Graeme M. ( 1987)
    For the surgery of the NUCLEUS Cochlear Implant (CI) in general anaesthesia we use a skin cut beginning at the bottom of the entrance to the outer ear canal, following the posterior circumference to a point nearly 12 o'clock. From here the incision runs superiorly to the tragus until two or three centimetres above the pinna base and in a wide smooth circle in direction to the occiput. The wide circle is necessary to get a distance of about 2 cm away from the package and also to guarantee the blood supply by the occipital artery and by the postauricular artery as well.

    The histopathology of the human temporal bone following cochlear implantation in a patient: a summary
    Clark, Graeme M. ; Shepherd, R. K. ; Webb, R. L. ; Franz, B. K-H. ( 1987)
    The macroscopic and microscopic evaluation of the implanted and unimplanted temporal bones in a patient who had a cochlear prosthesis for 27 months prior to his death from cardiac disease has shown that the device is biocompatible, and does not lead to any significant adverse effects. The cause of deafness was meningitis.
