3D printing is becoming increasingly important to neurosurgical applications, including new surgeon training, the simulation of complex anatomical pathways, pre-surgical planning and patient education. A recent paper from the , , and medical 3D printing specialists focuses on how they created a novel, anatomically accurate model of the skull base using Synopsys Simpleware technology. The value of the final model is that it enables the exploration of key neurovascular components and the trajectory of the facial nerve within the temporal bone.
With gradual reductions in undergraduate anatomy curricula and access to cadaveric training, 3D printed anatomical models have become increasingly important as adjunctive teaching tools. For skull base surgeries, scanning and printing models offers a valuable resource for reducing the risk of damage from drilling into the temporal bone. The researchers in this paper therefore wanted to create a truly scalable 3D printed model of the skull base, including the relational anatomy of the brainstem, cranial nerves, and the neurovascular network. In addition, the model was designed to visualize the cochlea, labyrinth, and facial nerve within the temporal bone, making it more valuable as a training aid for students and more experienced surgeons.

While the full workflow for the simulation can be found in the researchers' paper, here is a brief summary of the materials and methods used:
The final 3D printed model provides a cost-effective, reproducible resource for medical education, with no complications from successful printing, and accurate representations achieved of the neurovascular contents of the skull base. As the first 3D printed model of the skull base in the researchers' department, it already carries strong value for teaching, and an economical alternative to cadaveric specimens ¨C the 3D printing process cost approximately $1,600 and took three days from printing to finalizing, with no storage or maintenance costs. In contrast, cadaveric specimens cost up to $2,000 to acquire, and a further $4,000-$6,000 to maintain.

Compared to previous 3D prints of the skull base, this new model is more comprehensive in terms of providing the trajectories of all twelve cranial nerves and their relationship to the anterior circulation within the skull base. The inclusion of a novel modifiable window for training also helps with pre-surgical planning for prospective patients, while the same 3D printing method can be used to generate miniature versions of the model as revision tools for students.
