Individuals without a functional auditory nerve, and patients for whom cochlear ossification renders cochlear implantation impossible, benefit from central auditory implants such as the Auditory Brainstem Implant (ABI) or the Auditory Midbrain Implant (AMI). In the past it was mainly patients suffering from neurofibromatosis type 2 (NF2) who received such implants. More recently, they have also been used for patients with meningitis-induced advanced cochlear ossification and children whose auditory nerve is absent. These central auditory implants have been co-developed at MHH’s Department of Otorhinolaryngology, and it was here that the world’s first AMI implantation was performed. These implants are the only way to restore hearing for this group of patients.

The 2nd generation AMI for patients with NF2 has recently become available at our clinic. If you are interested and would like to inform yourself without obligation, we would be happy to present the new implant to you in a personal conversation.
