Objective:
Aim of this paper is to prove the applicability of intra-operative recordings of auditory brainstem responses during cochlear implantation.
Methods:
The clinical practicability of intra-operative monitoring of hearing thresholds (Notched-Noise BERA, Amplitude Modulation Following Response [AMFR]) is presented in the respective case. The recordings were performed prior to the cochlear implantation and were compared with those obtained during and after cochlear implantation.
Results:
It is demonstrated that the patient's cochlear function can be monitored; residual hearing is available after surgery.
Conclusion:
The possibility of monitoring of hearing thresholds may add some security to the concept of electric-acoustic stimulation.
