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

Figure 17

As Figure 16, but now the results of different electrode arrays are shown in grouped bar plots (cf. Figure 3(b)). This means visualizing the results highlights the fact that the influence of cochlear size on trauma risk is less than the actual curling behaviour of the implant. This becomes clear if one compares, for example, the probability of trauma grade III in autoAOS for all three different cochleae. The grouped bar plots are quite similar in appearance (elliptical label), implying that there is not much difference in trauma risk between a small or a medium-sized cochlea. By contrast, in each ellipse, the results for different electrode arrays vary strongly, indicating a strong influence of electrode curling behaviour on the degree of exposure involved in the insertion process.
