Three-dimensional (3D) computer assisted temporal bone surgery

Standard two-dimensional (2D) high quality CT or MRI provides valuable information on anatomical relationships between important structures in temporal bone, but this 2D CT or MRI displays some shortcomings. If two important anatomical structures are not on the same CT or MRI scan, it is not always easy to understand their relationship. Also, we can not sometimes judge the depth of the field. The aim of our study was to design a computer program for 3D imaging of anatomical structures of temporal bone. Procedure steps: 1. Transmission of video or digital signal from CT device to the computer ; 2. Transmission of that signal using computer network to different locations ; 3. Special software for 3D modelling, partially created and modified by ourselves for 3D computer assisted surgery ; 4. Connection of the 3D-digitalizer with computer and multimedia navigation through computer during the surgery. Performing our 3D-approach in computer assisted temporal bone surgery, we were able to "look inside" the patient during surgical planning as well as at the time of the surgery
