Melbourne: A new research that uses stem cells for regrowing the damaged nerves that connect the ear to the brain in a hearing impaired person is underway, if successful it may cure deafness. A Melbourne-based researcher, Bryony Coleman has been conducting world-first research into the potential of stem cells to regrow the nerves that connect the ear to the brain at the Eye and Ear hospital here. If successful, it could improve the quality of hearing in people with Cochlear Implants (CI), and even help restore hearing, according to a researcher. A Cochlear Implants is surgically implanted electronic device that provides a sense of sound to a person who is hearing impaired. "Fifty years down the track this might be one of many techniques, we might not even need a CI," Coleman was quoted as saying in 'The Age' today. When a rock concert, pneumatic drill or blaring iPod destroys some of the tiny, vibrating hairs in the inner ear, the damage does not stop there. Destruction of each hair cell leads to the death of up to 10 nerves that carrys sound information to the brain, she said.
