For some time now, the Hearing Implant Center at Inselspital has been offering the auditory brainstem implant (ABI). This expands the range of hearing implants and therapies for deaf or hard of hearing patients. This interdisciplinary procedure, performed by ENT surgeons, ENT engineers and neurosurgeons from Inselspital, is supported by the expertise of Prof. Dr. Robert Behr, a world-renowned pioneer in this field. He has come from abroad especially for this rare and demanding operation.

Prof. Dr. Behr, a neurosurgeon, has not only performed this procedure himself all over the world, but has also introduced neurosurgeons and ENT specialists from Asia, America, Africa and Europe to ABI implantation. He was the first surgeon worldwide to connect an electronic microprobe directly to the auditory nerve nucleus in the brainstem of a patient. Since then, he has performed more than 180 of these demanding surgeries – mostly on children.

An auditory brainstem implant is used for disorders in the area of the auditory nerve that prevent or block the transmission of sounds to the brainstem. The resulting hearing experience with the implant enables an improvement in lip-reading and the ability to distinguish between everyday sounds. In exceptional cases, even free word comprehension can be achieved.

The procedure requires close collaboration across various disciplines: an interdisciplinary team evaluates in advance whether a patient is suitable for such an intervention. During the operation itself, the neurosurgeon places the electrodes on the brainstem in collaboration with the ENT surgeons and ENT engineers, who are responsible for the measurements. Anesthesia and nursing also play an important role.

Hearing rehabilitation by the ENT department follows the procedure. ENT engineers, ENT hearing aid acousticians and speech therapists support patients with ABI over a longer period of time to optimize device settings and thus the hearing experience.
