A new method for template-guided cochlear implantation surgery is proposed which has been developed to create a
minimally invasive access to the inner ear. A first design of the surgical template was drafted, built, and finally tested
regarding its accuracy. For individual finalization of the micro-stereotactic frame bone cement is utilized as this well-known
and well-established material suggests ease of use as well as high clinical acceptance and enables both sterile and
rapid handling. The new concept includes an alignment device, based on a passive hexapod with manually adjustable
legs for temporary fixation of the separate parts in the patient-specific pose until the bone cement is spread and finally
cured. Additionally, a corresponding evaluation method was developed to determine the accuracy of the microstereotactic
frame in some initial experiments. In total 18 samples of the surgical template were fabricated based on
previously planned trajectories. The mean positioning error at the target point was 0.30 mm with a standard deviation of
0.25 mm.
