Cochlear Implants
The MAESTRO Cochlear Implant System

If you or someone you care about is affected by severe to profound hearing loss, a cochlear implant system from MED-EL may be an effective solution. A cochlear implant system is a medical option for individuals with severe to profound sensorineural hearing loss. For individuals with this type of hearing loss, hearing aids provide little or no benefit.

Users choose the MAESTRO Cochlear Implant System because it offers a superior hearing experience in real-life situations. The system contains features optimised for the appreciation of music and for listening in challenging situations.

MAESTRO consists of both an internal cochlear implant and an externally worn audio processor.
