“…Besides the 3D reconstruction of individual anatomy from tomographic data, a major focus was on predicting soft tissue changes due to bone relocations 13,14,15,16,17,18,19,20]. Only a few research groups did focus on an integrated 3D planning approach 21,22,23,24].…”

In cranio-maxillofacial surgery physicians are often faced with the reconstruction of massively destroyed or radically resected tissue structures caused by trauma or tumours. Also corrections of dislocated bone fragments up to the complete modeling of facial regions in cases of complex congenital malformations are common tasks of plastic and reconstructive surgeons. With regard to the individual anatomy and physiology, such procedures have to be planned and executed thoroughly in order to achieve the best functional as well as an optimal aesthetic rehabilitation. On this account a computer-assisted modeling, planning and simulation approach is presented that allows for preoperative assessment of different therapeutic strategies on the basis of three-dimensional patient models. Bone structures can be mobilized and relocated under consideration of anatomical and functional constraints. The resulting facial appearance is simulated via finite-element methods on the basis of a biomechanical tissue model, and visualized using high quality rendering techniques. Such an approach is not only important for preoperative mental preparation, but also for vivid patient information, documentation, quality assurance as well as for surgical education and training.

“…It is useful to have an instantly available digital reference with labeled sections because 3D diagnostic imaging in radiology is advancing rapidly (Romeny et al, 1998), as is image-related planning of surgical procedures (Sarti et al, 1999). In this context, the present atlas with its extensively labeled images, the correlated CT/MRI images, and its motion pictures is a valuable resource.…”

We present an online anatomy atlas based on the Visible Human Project (VHP) of the US National Library of Medicine. The objective is to provide original unlabeled as well as labeled sections of the human body of high quality and resolution on the Internet, for use in basic and continuing medical education. For a representative overview of the body, 370 axial sections were selected from the male and female data base of the VHP with special regard to regions of clinical interest. Each section is accompanied by its corresponding computer tomography (CT) image and, if available, magnetic resonance images (MRI) for quick and easy comparison of morphologic and radiologic structures. The sections can be studied unlabeled or labeled according to the current Terminologia Anatomica. A linked vocabulary with more than 850 terms explains the labeling. Animations of the sections as well as of CT and MR images allow for further visualization of the topographic relationships of anatomical structures. The responses to the project indicate that students and physicians regard the Internet Atlas of Human Gross Anatomy as a most useful aid for learning and reviewing anatomical details. The atlas is accessible on: http://www.uni-mainz.de/FB/Medizin/Anatomie/workshop/vishuman/Eready.html.

“…However, the method is not particularly appropriate in surgical planning due to the computational power needed and its high memory usage (Mollemans et al, 2007). For this deformation model to run at a reasonable speed special computers are needed with higher processing capabilities than is envisaged to be available on personal computers for some time (Sarti et al,1999). …”

Objectives:To determine the validity of 3dMD Vultus in predicting soft tissue morphology following orthognathic surgery. Methods:Thirteen patients with a skeletal discrepancy that required surgical correction limited to a Le Fort I surgical advancement osteotomy were included within the study. These patients had previously undergone a CBCT scan immediately before surgery (T1) and 6 months after surgery (T2).To permit validation, hard and soft tissues were linked for each time point and the hard tissues superimposed on the cranial vault and base. Using 3dMD Vultus virtual surgery was carried out to position the mandible and maxilla at T1 to the post-surgical position at T2. The resulting 3D soft tissue prediction mesh was then compared to the actual soft tissue mesh at T2 by segmenting both meshes at distinct anatomically areas of the face. The absolute distance between meshes for each region was then calculated using a custom developed computer program.
