title: Virtual exploration and comparison of linear mastoid drilling trajectories with true-color volume rendering and the visible ear dataset.
abstract: This paper provides instructions for a virtual exploration and self-study of surgical approaches within the temporal bone. Linear drilling trajectories in the sense of "keyhole" accesses are compared with true-color rendering techniques using freeware to introduce and evaluate new otologic approaches. On the basis of public-domain cyro-histology image data from a temporal bone six different drill trajectories are presented. This virtual method has the potential to be a first step in investigation of new surgical approaches before moving to cadaver testing.
