Abstract
Temporal bone anatomy is very difficult to understand. After dataset acquisition of the first Chinese Visible Human, we processed the two-dimensional images to build a digitized visible model of the temporal bone and explore the role of virtual endoscopy in the inner ear. On a SGI workstation three-dimensional computer reconstructions of the ear were generated from the Chinese visible human dataset, viewing the middle and inner ear imitating the traditional otoscopy. The three-dimensional data of the temporal bone were then converted to STL format, and the temporal bone replica were fabricated with rapid prototyping by laminated object manufacturing. The virtual model of the ear was successfully completed, and the virtual endoscopy improved three-dimensional visualization of the middle and inner ear. Physical replica of the temporal bone were built with paper; the accuracy was ±0.2 mm. The reconstructed model and the replica of the temporal bone can be used to make preoperative plans in the complicated otoneurosurgical operations, allowing various surgical exercises to be carried out on the three-dimensional stereophysical model. The virtual endoscopy stands as a promising new visualization technique for elucidation of the middle and inner ear and reveals a tremendous potential in both clinical and educational settings, providing morphological data for the image diagnosis and otoneurosurgery.
