Abstract
Introduction Navigation in neurosurgery has expanded rapidly; however, suitable models to train
end users to use the myriad software and hardware that come with these systems are
lacking. Utilizing three-dimensional (3D) industrial rapid prototyping processes,
we have been able to create models using actual computed tomography (CT) data from
patients with pathology and use these models to simulate a variety of commonly performed
neurosurgical procedures with navigation systems.
Aim To assess the possibility of utilizing models created from CT scan dataset obtained
from patients with cranial pathology to simulate common neurosurgical procedures using
navigation systems.
Methodology Three patients with pathology were selected (hydrocephalus, right frontal cortical
lesion, and midline clival meningioma). CT scan data following an image-guidance surgery
protocol in DIACOM format and a Rapid Prototyping Machine were taken to create the
necessary printed model with the corresponding pathology embedded. The ability in
registration, planning, and navigation of two navigation systems using a variety of
software and hardware provided by these platforms was assessed.
Results We were able to register all models accurately using both navigation systems and
perform the necessary simulations as planned.
Conclusion Models with pathology utilizing 3D rapid prototyping techniques accurately reflect
data of actual patients and can be used in the simulation of neurosurgical operations
using navigation systems.
