To enhance the quality in cochlear implantation (CI) the measurement of the cochlear duct length (CDL) and the determination of the electrode contact frequency (ECF) comes to the fore. Usually these items were investigated by computed tomography (CT). The determination of the ECF was only possible by research programs so far. The flat-panel-volume-tomography (fpVCT) allows a high spatial resolution for the visualization of the fine temporal bone structures. OTOPLAN® is a newly developed software, which enables the evaluation of CDL and the determination of postoperative ECP. The aim of this study was to investigate, if the combination of fpVCT and OTOPLAN® will help to implement an anatomically based cochlear implantation.

30 patients were included in the study, who received a CI (MED-EL) and had a preoperative CT of the temporal bone and a postoperative fpVCT for position control of the electrode. Determination of pre- and postoperative CDL and ECP was determined by OTOPLAN.

The use of OTOPLAN® was highly satisfactory due to the user-friendly interface and the integrated tools for the analysis of the cochlea. Measurement of the CDL was highly reliable using fpVCT with lower variance between the respective measurements compared to CT. Determination of ECF was clearly improved in fpVCT compared to CT. Preoperative computed ECF in CT corresponded to the postoperative values using fpVCT.

The combination of fpVCT and OTOPLAN® permits a simplified and more exact analysis of the cochlea in the pre-and postoperative period. The application of both systems together will lead to an improved system for the development of an anatomically based cochlear implantation system.
