Abstract

頭蓋底外科練習用モデルの作製方法について報告した.削開可能な市販の頭蓋骨モデルを基に,海綿静脈洞の内外壁をシリコーン製の硬膜2層構造で再現するとともに,人工脳神経や人工内頚動脈を再現した.Periosteal bridgeを人工骨膜で再現したり,動眼神経を前床突起の外下方に留置するなど,頭蓋底外科に重要な構造物の再現に留意した.電線を用いて椎骨脳底動脈を再現し,シリコーン製の小脳テントを再現した.これらの構造物を作製しながら,頭蓋底外科に必要な3次元的解剖の理解が可能である.

The procedures are shown to make a skull base model (M-model) for training in skull base surgery. The commercially available prototype dissectable skull model is used. The periorbita and inner layer of the cavernous sinus are made of yellow silicone. The cavernous sinus and its related structures are reconstructed with a double layer of silicone, cranial nerves made of rubber fiber, and carotid artery made of vinyl tube. The artificial oculomotor nerve should be located in the infero-lateral part of the anterior clinoid process. The periosteal bridge is also made of yellow silicone. The dural sinuses are made of blue silicone. The dura propria is reconstructed with brown silicone brushed onto the inner surface of the skull. Cranial nerves made of rubber fibers are positioned in the corresponding foramina. The vertebro-basilar artery made of wire is fixed with glue. Finally, the tentorium made of silicone is positioned and the outer layer of the cavernous sinus made of brown silicone. The processes to make the skull base structures facilitate better understanding of the three-dimensional cranial anatomy. This M-model is a useful training model for skull base surgery.
