Sunday, 25 March, 2001, 23:11 GMT 00:11 UK - Source: BBC News Ear cells 'could restore hearing' Technology could end deafness for some. Scientists have engineered ear cells that could be transplanted into humans to arrest hearing loss or even regenerate long-lost hearing. The work has been carried out by Professor Matthew Holley, of the University of Bristol. He envisages the cells working in tandem with inner ear implants to restore hearing by promoting nerve regeneration. Professor Holley will unveil his work at a conference on Genetics and Deafness organized by the charity Defeating Deafness and the UK Council on Deafness in London on Monday. He said: "Cochlear implants, small devices which stimulate the auditory nerve, work very well in a limited way. "But they cannot be given to long-term deaf people because their auditory nerves have degenerated too far. Electrical contact This opens up the prospect of making implants more effective and using them on a much wider scale Professor Matthew Holley, University of Bristol "Replacement nerve cells could improve the electrical contact between the implant and the brain. "This opens up the prospect of making implants more effective and using them on a much wider scale. "We may be in a position to make these advances in three to five years' time." A spokesperson for the Royal National Institute for Deaf People (RNID) said: "Currently, not all deaf people can benefit from a cochlear implant. Professor Holley's work on nerve regeneration may broaden this scope. "RNID welcomes any progress which may open up the possibility of benefiting from a cochlear implant to those deaf people who would wish to have one. "We look forward to studying the results of the research." |
