Objective: Due to the patients wish for a less traumatic, minimal invasive cochleostomy or opening of the
internal auditory canal without any mastoidectomy, we generate a surgical multiport approach at the temporal
bone. In contrast to other studies here we developed for the first time a multichannel approach to the surgical
target at the temporal bone.
Study Design: Feasibility study performed by cadaveric temporal bones.
Subjects and Methods: Drilling of three channels were performed on different cadaveric temporal bone
specimens. The drilling procedure was realized by a special developed frame, srew fixed at the bony head, with
a high precision mechatronic positioner. The drilling procedure was controlled by a new developed CT imaging
technique: to reduce the radiaton dose the presurgical diagnostic scan will be improved by superresolution
algorithmen technique. The deviation of the drilled paths from the desired path was radiologically and
metrolgocially analyzed.
Results: In all procedures the target was reached without damaging critical structures like facial nerve, brain or
ossicles. The precision of the drill procedure was comparable to the predictive value.
Conclusion: The multiport approach would be a possible alternative to different targets at the temporal bone
without any mastoidectomy. Furthermore we consider, that the evaluation should be based on metrological data.
