Three-Dimensional Computerized Anatomy

Introduction: The goal of this study was to develop a three-dimensional (3D) computerized anatomical model for microneurosurgical anatomy education.

Methods: The 3D model was made using commercially available software Maya 6.0 Unlimited (Alias Systems Corp., Delaware, US) in personal computer and one cadaver. Photos of the cadaver from superior and lateral views with at least two angles were imported to the 3D software to upper window, lateral window, respectively as the reference. Many photos were needed for making model in anatomically complex area. Careful dissection was needed not to conceal the important tissue from 2 views, and landmarks which can be foramen, bone, dura matter and so on, were remained for reference points.

Results: The 3D normal microneurosurgical anatomy model was made. The model was able to be seen from any angle. Viable transparencies assigned any tissue were shown the hidden part in operative view. We are able to insert the anatomical name label to 3D model for educational purpose.

Conclusion: This developed computer-generated 3D model can be observed repeatedly without time limit and any stress like in operating room. This model is useful not only for anatomical education but also for the training of visuospacial ability to gain more accurate and rich mental 3D representations, which correlates the surgical skill. We want to be able to use this model in any personal computer in the future.
