Simulation of the anterior interhemispheric-lamina terminalis approach (craniopharyngioma model). The structures adjacent to the tumor were observed and the advantages and disadvantages of the transpterional approach (a) and interhemispheric approach (b) were compared to determine the surgical approach. The surgical approach was selected, and the lamina terminalis was opened to expose the tumor. The simulation results (c) were consistent with the intraoperative findings (d) (1: Prefixed optic chiasm; 2: Anterior communicating artery; 3: Lamina terminalis) (VR: Blue - ventricles; Green – tumor; Red – arteries; Yellow - bone mass; White - optic nerve).
