    The relationship between aetiology of hearing loss and outcome following cochlear implantation in a paediatric population
    O'Sullivan, P. G. ; Ellul, S. M. ; Dowell, B. C. ; Clark, Graeme M. (Monduzzi Editore, 1997)
    Eighty-eight children who underwent cochlear implantation at the University of Melbourne Cochlear Implant Clinic are reviewed. The aetiology of the hearing loss is classified and is compared to their best level of speech perception performance. The group whose hearing loss was not congenital in origin performed better than those who were congenital in origin. Of those whose hearing loss was congenital in nature those with rubella appeared to perform best.

    Factors affecting outcomes in children with cochlear implants
    Dowell, R. C. ; Blamey, P. J. ; Clark, Graeme M. (Monduzzi Editore, 1997)
    Open-set speech perception tests were completed for a group of 52 children and adolescents who were long-term users of the Nucleus multiple channel cochlear prosthesis. Results showed mean scores for the group of 32.4% for open-set BKE sentences and 48.1% for phonemes in open-set monosyllabic words. Over 80% of the group performed significantly on these tas1cs. Age at implantation was identified as a significant factor affecting speech perception performance with improved scores for children implanted early. This factor was evident in the results at least down to the age of three years. Duration.. of profound hearing loss, progressive hearing loss, educational program and preoperative residual hearing were also identified as significant factors that may affect speech perception performance.

    Intracochlear factors affect the auditory brainstem response to intracochlear electrical stimulation in cat [Abstract]
    Araki, Susumu ; Kawano, Atsushi ; Seldon, Lee ; Clark, Graeme M. (Karger, 1996)
    Cochlear implants are one treatment for children who are born deaf or become deaf before acquiring language. It is hypothesized that several factors within the cochlea may influence the performance of an implantee. Such factors could include the number and distribution of surviving spiral ganglion cells and the presence of fibrous tissue and/or new bone growth.
