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

Figure 20

Comparison of the relationship between implant feed ( axis) and stylet extraction ( axis) for the AOS technique (red dotted line, strong linear relationship as recommended by the manufacturer) and for the optimized insertions (grey lines). The black line indicates an averaged profile for stylet extraction during the insertion process; even this small change appears to be advantageous compared with the conventional AOS technique.
