Clinical approach to facial stimulation in cochlear implants




nervio facial, implante coclear, estimulación eléctrica, pulsos eléctricos, modos de estimulación


Cochlear implants are currently one of the most successful neurosensory rehabilitation devices. They provide the possibility of hearing in people with severe to profound hearing loss who have had limited access to sounds with hearing aids. However, there are complications after its implantation, among which is the stimulation of the facial nerve. The main detriments produced by this unwanted stimulation are involuntary movements of the face or neck, discomfort or pain when using the implant, among others. In some cases, this happens only on few channels, but it can also appear on most or even all of them.

The current clinical approach to this problem mainly relies on changes in the programming of the device. The resources to reduce it range from changes in the type and mode of the electrical stimulation, to considering reimplantation in very complex cases. This article describes the problem of facial stimulation and its possible causes, as well as details the clinical solutions that currently exist. Finally, new approaches and future lines of research are discussed.
