Individual Optimization of the Insertion of a Preformed Cochlear Implant Electrode Array

Figure 7

Graphical user interface (GUI) of the custom-made simulation tool “SimCInsert.” It enables visualisation of both the geometrical data for the investigated inner ears (1, here: medium-sized) and the shape of the electrode arrays (2, here: RE06). Using the slider (3), the stylet (not visualized) can be virtually moved; that is, the array’s shape is manipulated. Using six cursor buttons (4, two for each interactively adjustable parameter , , and ), the location and orientation of the electrode array for each shape can be manipulated with respect to the cochlea plotted at the same (fixed) position. Use of both input options enables a complete insertion process to be simulated. Radio buttons (5) were included to interactively rate the risk of insertion trauma (see Section 2.5).
