頭蓋底アプローチにおける術前シミュレーションの有用性

Usefulness of Preoperative Simulation: Skull Base Approach

Point

・術前シミュレーション画像作成により，術野イメージが明確に視覚化できるので，手術計画立案に有用である．

・仮想手術が可能となるので，デジャブ効果が得られる．

・手術教育という点でも有用である．

　Preoperative simulation images creates an accurate visualization of a surgical field. The anatomical relationship of the cranial nerves, arteries, brainstem, and related bony protrusions is important in skull base surgery. However, an operator's intention is unclear for a less experienced neurosurgeon. Three-dimensional（3D）fusion images of computed tomography and magnetic resonance imaging created using a workstation aids precise surgical planning and safety management. Since the simulation images allows to perform virtual surgery, a déjà vu effect for the surgeon can be obtained. Additionally, since 3D surgical images can be used for preoperative consideration and postoperative verification, discussion among the team members is effective from the perspective of surgical education for residents and medical students. Significance of preoperative simulation images will increase eventually.
