Abstract
The presentation of the surgical anatomy of the temporal bone by standard a natomical figures is not suitable for otosurgical training. For the compreh ension of its complex morphology temporal bone drilling is inalienable. Aim of the present cooperation was to gain an interactive real-3D program for the simulation of specific laterobasal surgical approaches. Methods: The pr ogram was derived from a standard horizontal section of a human temporal bo ne using a Siemens Somatom Plus 4 Tomograph. The slice thickness was 1 mm, the image matrix was 512(2). The Voxel-Man-system was used to built up the application for unix workstations. Results: Each step of a surgical approac h to the temporal bone can be performed by the present computer model. Calc ulation in a stereo mode even allows spatial 3D- perception when using red/ green glasses. Conclusions: This program is a novel tool to simulate critic al aspects of otosurgical procedures on a computer. Up to now the lack of t actile and kinesthetic information does not allow to renounce individual te mporal bone drilling.
