    Surgical complications with the cochlear multiple-channel intracochlear implant: experience at Hannover and Melbourne
    Webb, Robert L. ; Lehnhardt, Ernst ; Clark, Graeme M. ; Laszig, Roland ; Pyman, Brian C. ; Franz, Burkhard K-H. G. ( 1991)
    The surgical complications for the first 153 multi-channel cochlear implant operations carried out at the Medizinische Hochschule in Hannover and the first 100 operations at The University of Melbourne Clinic, The Royal Victorian Eye and Ear Hospital, are presented. In the Hannover experience the major complications were wound breakdown, wound infection, electrode tie erosion through the external auditory canal, electrode slippage, a persistent increase in tinnitus, and facial nerve stimulation. The incidence of wound breakdown requiring removal of the package was 0.6% in Hannover and 1.0% in Melbourne. The complications for the operation at both clinics were at acceptable levels. It was considered that wound breakdown requiring implant removal could be kept to a minimum by making a generous incision and suturing the flap without tension.

    Surgery for the safe insertion and reinsertion of the banded electrode array
    Clark, Graeme M. ; Pyman, B. C. ; Webb, R. L. ; Franz, B. K-H. G. ; Redhead, T. J. ; Shepherd, R. K. ( 1987)
    Adhering to the surgical technique outlined in the protocol for the Nucleus implant has resulted in over 100 patients worldwide obtaining significant benefit from multichannel stimulation. A detailed analysis of the results in 40 patients shows that it improves their awareness of environmental sounds and their abilities in understanding running speech when combined with lipreading. In addition, one third to one half of the patients also understand significant amounts of running speech without lipreading and some can have interactive conversations over the telephone. It is clear that any insertion trauma is not significant, which is confirmed by the excellent clinical results.
