ItemThe role phase-contrast imagining in intra-cochlear electrode developmentWilkins, S. ; Saudners, E. ; Clark, Graeme M. ; Cowan, R. ; XU, JIN ; Stevenson, A. W. ; Gao, D. ; Tykocinski, M. ; Cohen, L. ; Dahm, Markus ( 2000)In order to improve the design of intracochlear multichannel electrode arrays, it is fundamental that we have knowledge of the exact anatomical , position of the electrode within the scala of the cochlea. Currently, conventional skull radiography is still the mainstay of post-operative radiological assessment of electrode positioning. The present work investigates the use of phase-contrast radiography, a new x-ray modality, to provide improved imaging of the inner ear and the intracochlear electrode array in the human temporal bone (TB).

ItemSafety studies and preliminary patient trails with a new perimodiolar electrode arrayClark, Graeme M. ; COWAN, ROBERT ; Saunders, Elaine ; TYKOCINSKI, MICHAEL ; COHEN, LAWRENCE ; Treaba, Claudiu ; BRIGGS, ROBERT ; Dahm, Markus ( 2000)A new perimodiolar electrode array, the curly-with stylet (CwS), has been developed and undergone safety trials in human cadaver temporal bones. The array was developed as a result of animal and modelling studies which indicated that there are potential advantages in situating the electrode array in closer proximity to the neural elements. Preliminary studies with four patients in Melbourne implanted with a developmental pre-curved array had supported the predictions of lower current requirements and possibly more focussed spread of excitation.
