Skull base architecture is tough to understand because of its 3D complex shape and its numerous foramen, reliefs or joints. It is especially true for the sphenoid bone whom central location hinged with most of skull base components is unique. Recently, technological progress has led to develop new pedagogical tools. This way, we bought a new real-time three-dimensional insight of the sphenoid bone that could be useful for the teacher, the student and the surgeon. High-definition photography was taken all around an isolated dry skull base bone prepared with Beauchêne's technique. Pictures were then computed to provide an overview with rotation and magnification on demand. From anterior, posterior, lateral or oblique views and from in out looks, anatomical landmarks and subtleties were described step by step. Thus, the sella turcica, the optic canal, the superior orbital fissure, the sphenoid sinus, the vidian canal, pterygoid plates and all foramen were clearly placed relative to the others at each face of the sphenoid bone. In addition to be the first report of the 360 Photography tool, perspectives are promising as the development of a real-time interactive tridimensional space featuring the sphenoid bone. It allows to turn around the sphenoid bone and to better understand its own special shape, numerous foramen, neurovascular contents and anatomical relationships. This new technological tool may further apply for surgical planning and mostly for strengthening a basic anatomical knowledge firstly introduced.
颅底结构因其三维复杂形状以及众多的孔、凹陷或关节而难以理解。对于蝶骨来说尤其如此，其中心位置与大多数颅底组件相连，这一点很独特。最近，技术进步促使开发了新的教学工具。通过这种方式，我们获得了蝶骨的全新实时三维视角，这对教师、学生和外科医生可能都有用。我们对一块用博尚技术处理过的孤立干燥颅底骨进行了全方位的高清拍摄。然后对图片进行处理，以便根据需要提供旋转和放大的全貌。从前、后、侧或斜视图以及内外视角，逐步描述了解剖标志和细微之处。这样，蝶鞍、视神经管、眶上裂、蝶窦、翼管、翼突板以及所有的孔在蝶骨的每个面上都相对于其他结构清晰定位。除了作为360度摄影工具的首次报告外，随着以蝶骨为特色的实时交互式三维空间的开发，前景很广阔。它能让人们围绕蝶骨转动，更好地了解其独特形状、众多的孔、神经血管内容物以及解剖关系。这种新的技术工具可能进一步应用于手术规划，主要用于强化最初介绍的基础解剖知识。
