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.
