Judicious bone resection is important to minimize CSF leak in endoscopic transnasal surgery. Lateral extent of bony resection is determined by the pathology, broader for a large craniophayngioma (right) then for a small tuberculum sella meningioma (left). https://t.co/Uz9aYTUIme

During resection of cavernous sinus meningiomas, first remove the components of the tumor affecting the optic nerve to protect the nerve during tumor manipulation & traction. Note aggressive devascularization of the tumor & its thorough internal debulking.

While resecting olfactory groove meningiomas, I dissect the arachnoid plane between the ipsilateral optic nerve/chiasm/carotid artery & the posterior capsule of the tumor. Early ID of these structures improves the efficiency & safety of the operation.

Olfactory groove meningiomas can be resected via a bifrontal craniotomy. I prefer a pterional craniotomy, no matter how large the olfactory groove meningioma. This approach is less invasive & allows early identification of the optic nerve & carotid artery
