| Outline of Final Research Achievements |
An accurate 3D temporal bone model would be useful as a training tool in surgical anatomy. However, temporal bone has many small structures and air-containing spaces, therefore the internal anatomical structures of the temporal bone model are not easily reproducible. To overcome these limitations, we made slight manual modifications to the conventional 3D printing method. After the optimal 3D temporal bone models were produced, anatomical fidelity was evaluated by macroscopic and endoscopic inspection, CT images, as well as dissection by several surgeons.
In results, macroscopic and endoscopic inspection, CT images, and assessment by surgeons were in agreement in terms of reproducibility of model structures. Most structures could be reproduced, but some small structures were unsatisfactory. Perioperative tactile sensation of the model was excellent. Although this model still does not embody perfect reproducibility, it proved sufficiently practical for use in surgical training.
