Update on anterior clinoid process removal in anterior clinoid meningioma surgery: literature review, and a new didactical concept

1

Anterior clinoid meningiomas are challenging to surgically treat due to their proximity to critical neural and vascular structures.
2

Visual impairment in patients with anterior clinoid meningiomas can reach 60%, often due to chronic ischemia and mechanical compression.
3

Anterior clinoidectomy is considered essential for tumor devascularization and reducing optic nerve manipulation during surgery.
4

Anatomical variations of the anterior clinoid process can complicate surgery and increase risks of cerebrospinal fluid leaks and internal carotid artery injuries.
5

The extradural anterior clinoidectomy technique is preferred for ACP removal, emphasizing the importance of minimizing thermal injury to the optic nerve.
