Surgical Theater® offers this technology and enables the neurosurgeon preoperatively to perform a virtual tumor removal and get familiar with the individual anatomy and pathology of the patient. Navigation and virtual reality are especially helpful planning minimally invasive surgeries. Using a minimally invasive retromastoid approach, Feigl, MD PhD operates on a T4 acoustic neuroma while being able to compare the 3D voxel based reconstruction of the patient with the intraoperative view. The acoustic neuroma was removed successfully and completely and the brainstem was decompressed. ↖ read less
