Low-Cost Stereotactic Brain Biopsy Simulation Model

Simulation training improves technical skills in a safe environment. Stereotactic techniques are widely used in neurosurgery for different kinds of procedures. The objective of the study was to describe a combined cadaveric and synthetic low-cost stereotactic simulation model and its validation by neurosurgeons. The brain was made using self-supporting gel with solid and cystic lesions. We used imaging scans to calculate x, y, and z target coordinates. A standard frame needle biopsy was performed. We calculated the number of mistakes and time needed to accomplish the task, and we evaluated the frame assembly and biopsy performance. Wilcoxon signed rank was used to analyzed the data; we considered a P value
