Summary
This study details creating 3D printed temporal bone models from CT scans for surgical training. These rapid prototypes offer an inexpensive and quick method for anatomical education.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- 3D Printing Technology
Background:
- 3D printing offers novel solutions for medical education.
- Accurate anatomical models are crucial for surgical training.
Purpose of the Study:
- To develop and describe a method for creating 3D printed, rapid prototype temporal bone models.
- Utilize clinical computed tomography (CT) images for model generation.
Main Methods:
- Segmentation of clinical CT data using freely available software.
- Generation of three-dimensional (3D) models from ABS plastic.
- Evaluation of anatomical accuracy and surgical drilling response.
Main Results:
- Models accurately represented external auditory canal dimensions.
- Key anatomical structures (malleus, incus, windows, facial nerve canal) were identifiable.
- Initial models required modifications for scaffolding material drainage; drilling produced bone-like dust.
Conclusions:
- A rapid prototype temporal bone model was successfully created using 3D printing and CT data.
- The models are cost-effective and quick to produce.
- Potential applications for surgical and anatomical education are highlighted.
