The Promise of Fully Implanted Cochlear Technology
The Acclaim® cochlear implant represents a potential paradigm shift in the treatment of severe to profound sensorineural hearing loss. Unlike traditional cochlear implants, which consist of an internal implant and an external sound processor worn behind the ear, the Acclaim is designed to be fully implanted. This innovation seeks to eliminate the need for any externally worn components, offering several significant advantages to patients.
Current cochlear implants, while highly effective, require daily management of the external processor, including battery changes, protection from water, and visibility.
