How we do it: Low frequency specific hearing monitoring during hybrid cochlear implantation

Advances in cochlear implant technology led to the combination of cochlear implant and hearing aid, and in that way provided a possibility to restore the high-frequency hearing in patients with partial deafness. This combined device called hybrid provides electroacoustic hearing. Because the low frequency in partial deafness is preserved or almost preserved, it is crucial to preserve function in the apical part of the cochlea. Residual hearing monitoring, particularly low frequency specific, during cochlear implantation could be very helpful for the better prevention of induced hearing loss. In this paper, we would like to present the way how we do it in our department on one case example.
