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

Figure 12

Histogram of the distribution (observation frequency) of the trauma risk where the procedure is performed in an automated manner. As no additional parameters could be adjusted to tailor the orientation of the electrode array, the simulation of the automated AOS technique (autoAOS) represents its most consistent implementation in this study. The histogram clearly shows the high portion of trauma risks III and IV on the insertion process. Only with RE07 is less trauma risk (≤I) observed. Of the electrode arrays in the study, RE07 is the one with the flattest curling curve and pronounced straightening in the initial phase.
