Poster Presentations P225POSTERS the predicted ELS. The path was visually verified to determine its relationship to the actual location of the ELS.Results: CT scans of 6 cadaveric temporal bones with boneimplanted fiducial markers were analyzed. The location of the ELS was predicted using traditional surgical landmarks. A custom Microtable (microstereotactic frame) was manufactured for each bone to target the ELS via a linear path (selected manually by CT). The bone was drilled to decompress the ELS. The Microtable was then mounted on the fiducial markers and the drill bit passed through its target hole to determine the actual targeted path. The drill bit coincided with the ELS in all specimens and did not transect any critical structures along its pathway.Conclusion: Current imaging technology allows for reliable identification of the ELS and generation of linear trajectories to reach the ELS without injury to adjacent structures. This work is the first step in the development of minimally invasive image-guided techniques to safely access the ELS in the treatment of Ménière's disease.
