Preoperative planning software automatically segments vital structures and determines an optimally safe trajectory from the lateral skull to the cochlea. This trajectory is used both for drilling to the cochlea and for the electrode array insertion tool. The software is also used to customize the stylet insertion depth and to determine the proper angle of the electrode array about the insertion axis.
