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.

During transcranial resection of tuberculum sella meningiomas, it's crucial to preserve the small branching vessels originating from the superior hypophyseal artery complex & the medial aspect of the internal carotid artery supplying the optic nerve/chiasm

Here, we see the relative distribution of the most common intracranial meningiomas. Resection of these benign tumors is associated with good patient outcomes and therefore is satisfying for neurosurgeons.

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.

During tentorial transection for a petrotentorial it's important to protect the trochlear nerve as it travels along the lateral edge of the incisura. The black dotted line represents an incision that allows us to avoid an injury to the nerve.

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
