Cochlear implants (CIs) are the standard of care for individuals with severe to profound hearing loss. They partially restore hearing by directly exciting the auditory nerve and nervous system. As of 2012, approximately 38,000 children and 58,000 adults had received CIs in the U.S. While CIs are the most successful of available neural prostheses, they do not fully restore hearing to the level of someone with normal acoustic hearing. Reasons for this include biological, technological, and clinical limitations of the device; we at MCICE are working to improve outcomes for individuals with CIs through research, education, and clinical services.
