Background
Removal of the anterior clinoid process expands the anterolateral corridor. Performed extradurally, the dura provides intracranial contents some protection.
Methods
The anatomy of the anterior clinoid process is described along with variants of the surrounding structures. In addition to an operative video, the anatomy and surgical technique is demonstrated in virtual reality space to enhance the didactic clarity.
Conclusion
The anatomical nuances of the lesser sphenoid wing in general, and the anterior clinoid process in particular, are complex. A demonstration in virtual reality takes advantage of the technological flexibility of multi-angled perspectives and focuses on the relevant key structures.
