Introduction.
In order to achieve a minimal trauma to the inner ear structures during array insertion, it would be suitable to control insertion forces.
The aim of this work was to compare the insertion forces of an array insertion into anatomical specimens with three different insertion techniques: with forceps, with a commercial tool, and with a motorized tool.
Materials and Methods.
Temporal bones have been mounted on a 6-axis force sensor to record insertion forces.
Each temporal bone has been inserted, with a lateral wall electrode array, in random order, with each of the 3 techniques.
Results.
Forceps manual and commercial tool insertions generated multiple jerks during whole length insertion related to fits and starts.
On the contrary, insertion force with the motorized tool only rose at the end of the insertion.
Overall force momentum was 1.16 ± 0.505 N (mean ± SD, n=10), 1.337 ± 0.408 N (n=8), and 1.573 ± 0.764 N (n=8) for manual insertion with forceps and commercial and motorized tools, respectively.
Conclusion.
Considering force momentum, no difference between the three techniques was observed.
Nevertheless, a more predictable force profile could be observed with the motorized tool with a smoother rise of insertion forces.
