Introduction
It is known from former investigations that several factors will affect the electrical compound action potentials. This includes the percentage and nature of neural survival, the presence of intra-cochlear tissue, and the cochlear anatomy. Additionally, there are implant related factors like the mode of stimulation, and the size and placement of the electrode array.
Materials and Methods
The aim of this prospective study is to investigate the recording of EAP signals elicited by the new PULSARci100 cochlear implant of MED-EL. A special EAP recording system is used to establish intra- and post-operative amplitude growth functions and recovery functions. This includes recordings from basal, middle, and apical regions of the cochlea. Today only the standard electrode array of the PULSARci100 allows stimulation at the apical third of the cochlea.
Results
Results will be presented as EAP recordings from different cochlear regions.
