The purpose of this Web site is to describe cochlear implants, link to FDA-approved implants, note the benefits and risks of cochlear implants, and provide news about cochlear implant recalls and safety issues. You can find information here too on what educators of implant users need to know, what happens before, during and after surgery, and where to report problems.
