The anatomical layers from the skin incision to the sella turcica were dissected step by step, and key neurovascular structures were identified. Results: The model successfully demonstrated critical neurovascular relationships, enabling trainees to visualize the optic nerve, internal carotid artery, anterior clinoid process, and parasellar structures. Participants (n=10 neurosurgery assistants) showed significant improvement in anatomical knowledge (pre-test: 84±11.7 vs. post-test: 96±5.16, p <0.05, Wilcoxon test) and procedural efficiency. The three-dimensional exposure facilitated skill acquisition in bone drilling, dural retraction, and vessel preservation. Conclusion: The presented model offers an effective and reproducible tool for teaching the anatomical details of the pterional approach. Future studies are recommended to expand the model with multiple cadavers and to assess its educational outcomes quantitatively.}, number={2}, publisher={Society of Anatomy and Clinical Anatomy}
