Summary
Children surviving cancer are often left with a severe permanent hearing loss. However, very little progress has been made to minimize hearing damage in this special population. Early detection of hearing damage is not possible using traditional assessment tools. The present research seeks to investigate the use of innovative testing techniques to identify hearing damage in the early stages of the disease with high accuracy.

However, very little progress has been made to minimize hearing damage in this special population. Early detection of hearing damage is not possible using traditional assessment tools. The present research seeks to investigate the use of innovative testing techniques to identify hearing damage in the early stages of the disease with high accuracy. If successful, the research will alter standard audiometric practice in hospital clinics around Australia, hence improving the standard of hearing health care for this group. The early diagnosis of hearing impairment will not only provide a chance for doctors to balance the therapeutic effects of anticancer drugs against the danger of a permanent hearing loss, but also enable allied health professionals and educational specialist to provide timely management strategies. The determination of the rate and extent of hearing dysfunction progression in children receiving chemotherapy, as proposed in this research, enables the ototoxic effects of existing drugs to be compared. With this approach, the ototoxic side effects of new drugs can also be evaluated. In summary, the proposed study will improve the quality and efficiency of audiological service delivery to young children undergoing chemotherapy in Australia and overseas.Read moreRead less
Evaluating Perceptual Benefits Of Bilateral Cochlear Implants For Young Children And Infants

Summary
The cochlear implant (bionic ear) has revolutionised communication for children with profound hearing loss. Nevertheless, children with the standard single implant still face huge challenges in educational and social settings. Difficulties include understanding speech that is soft, or speech in noisy environments, such as the classroom. Also, with one implant, children cannot locate the source of sound, such as the speaker in a group conversation, team-mates during sport, or an oncoming car.

Nevertheless, children with the standard single implant still face huge challenges in educational and social settings. Difficulties include understanding speech that is soft, or speech in noisy environments, such as the classroom. Also, with one implant, children cannot locate the source of sound, such as the speaker in a group conversation, team-mates during sport, or an oncoming car. Research with other normal hearing and hearing impaired groups suggests that two (bilateral) implants may possibly improve performance in these conditions. Although hundreds of children worldwide have received bilateral implants, very limited evidence is available to indicate whether two implants are significantly better than one, especially for young children. The main aim of the research is to evaluate the improvement in listening performance when young children and infants use two implants as compared with one. An additional aim is to gain clinical knowledge of bilateral implant use in order to develop selection criteria and management protocols for young bilateral candidates in the future. Results of this research will determine if bilateral implants should become a standard option for young children at the RVEEH-University of Melbourne Implant Clinic. The results will be published and presented internationally to influence clinical practice worldwide. All children using a cochlear implant, or in need of one in the future, will benefit as the study outcomes will indicate the best choice of hearing devices for individual children, and help to determine best-practice management if bilateral implants become an option for all children.Read moreRead less
