A computed tomographic data-based vibrant bonebridge visualization' tool

摘要

Aim: Information about the temporal bone size and variations of anatomical structures are crucial for a safe positioning of the Vibrant Bonebridge B-FMT. A radiological based preoperative planning of the surgicalprocedure decreases the surgical time and minimizes the risk of complications. Materials and methods: We developed a software tool, which allows a catch up of foreign DICOM data based CT temporal bone scans. The individual CT scan is transmitted into a 3D reconstructed pattern of the temporal bone. In this 3D reconstruction the individually favored position of the B- FMT should be found. Results: The software allows a determination of a safe B-FMT position by identifying the individual relation of middle fossa, jugular bulb and external auditory canal. Skull thickness and screw length are contained parameters for the surgical planning. Conclusion: An easy to handle software tool allows a radiologically data based safe and fast surgical positioning of the B-FMT.
