Lasers Can Improve Hearing

Facebook X LinkedIn Email
HANNOVER, Germany, April 20, 2012 — New technologies to improve the insertion techniques and exact fitting of cochlear implants in the inner ear could soon provide better-quality residual hearing for more than 200,000 hard-of-hearing people worldwide. Approximately 95 percent of those who are highly hearing impaired have an adequately intact auditory nerve, enough to provide at least partial hearing. To aid hearing, a cochlear implant — an electrical acoustic aid or prosthesis — takes over the function of damaged sensory cells in the inner ear. This device consists of an implant placed in the bone under the...Read full article
