Purpose.
The aim of this study was to show that individual adjustment of the curling behaviour of a preformed cochlear implant (CI) electrode array to the patient-specific shape of the cochlea can improve the insertion process in terms of reduced risk of insertion trauma.
Methods.
Geometry and curling behaviour of preformed, commercially available electrode arrays were modelled.
Additionally, the anatomy of each small, medium-sized, and large human cochlea was modelled to consider anatomical variations.
Finally, using a custom-made simulation tool, three different insertion strategies (conventional Advanced Off-Stylet (AOS) insertion technique, an automated implementation of the AOS technique, and a manually optimized insertion process) were simulated and compared with respect to the risk of insertion-related trauma.
The risk of trauma was evaluated using a newly developed “trauma risk” rating scale.
Results.
Using this simulation-based approach, it was shown that an individually optimized insertion procedure is advantageous compared with the AOS insertion technique.
Conclusion.
This finding leads to the conclusion that, in general, consideration of the specific curling behaviour of a CI electrode array is beneficial in terms of less traumatic insertion.
Therefore, these results highlight an entirely novel aspect of clinical application of preformed perimodiolar electrode arrays in general.
