Objective: The aim of this research was to evaluate a deformable simulation system that can be operated simply and quickly, aiming at daily use in clinical practice of neurosurgery. We examined whether this method would be useful for preoperative simulation.Methods: Subjects comprised 10 patients who underwent microneurosurgery. Using Avizo 5.1 computer visualization software, the 3-dimensional images were created from preoperative 2-dimensional DICOM (Digital Imaging and Communication in Medicine) data. A brain retraction simulation program was added to Avizo 5.1. We evaluated the simplicity of the operation, and usefulness in preoperative review.Results: With this software, we performed a virtual simulation of brain retraction. Between 3 minutes (minimum) and 30 minutes (maximum), 3-dimensional spatial relationships between nerves, vessels, skull, brain surface, and how to retract brain surfaces such as direction and degree of brain retraction are easily recognized.Conclusion: Virtual operative simulation of brain retraction with this system was simple, quick and effective for surgery review in the neurosurgical field.
