    Pre-operative hearing assessment in young cochlear implant candidates
    RANCE, GARY ; Dowell, Richard C. ; Rickards, Field W. ; Clark, Graeme M. ( 2000)
    Early implantation of congenitally deaf candidates is now a goal of most cochlear implant clinics. This objective can only be achieved through the use of audiological tests that are able to identify and quantify hearing loss in infancy. Behavioural conditioning techniques provide the most accurate indication of hearing acuity in older subjects, but these procedures are unreliable in young (6 months) or developmentally delayed children. This paper investigates the degree of accuracy with which two electrophysiological test techniques (click-ABR & steady-state evoked potential [SSEPD can be used to assess auditory function in infants with significant hearing loss. ABR and SSEP findings from 108 children were compared with hearing levels obtained behaviourally.

    How much residual hearing is too much?
    Cowan, R. S. C. ; Dowell, R. C. ; Psarros, C. ; Dettman, S. J. ; Rance, G. ; Clark, Graeme M. ( 2000)
    The value of cochlear implants as an established clinical option for profoundly hearing-impaired adults and children has been supported by significant research results over a number of years (U.S. National Institutes of Health Consensus Statement 1995). As a direct consequence of the level of benefits shown for cochlear implant users on measures of speech perception, research has focused on investigating whether severely hearing impaired adults and children would be suitable candidates for cochlear implantation. I n considering the candidature of any individual, both medical and audiological suitability are investigated. The primary concern is to establish to what degree the patient would benefit from use of the cochlear implant.
