For STA-MCA revascularization, the initial incision is conducted distally along the length of the STA and carried proximally. The surgeon must take care not to incise too deeply to avoid injuring the STA and its branches w/in their subcutaneous course.

When performing a midline supracerebellar craniotomy for pineal region #tumor, 1-2 midline bridging veins are sacrificed during mobilization of the cerebellum. The precentral cerebellar vein leading to the superior vermian vein can be sacrificed safely.

Let’s jump right into the #neuroanatomychallenge. Pictured here is an endoscopic endonasal cartoon view of the internal carotid artery. What is the structure? Comment below with your guesses and check back tomorrow for the answer and a fun fact about this interesting structure!

In this video, Dr. Cohen performs removal of a left medial occipital arteriovenous malformation (#AVM).

The Knosp-Steiner classification describes tumor invasion of the cavernous sinus and is based on encasement of the carotid artery from the medial intercarotid line (grade 0) to beyond the lateral intercarotid line (grade 3). Grade 4 is full encasement.

To complete our mini-series on CSF leak repair, a gasket closure technique can be used to repair the defect in expanded transsphenoidal #skullbase approaches. The defect is covered w/a dural substitute, then buttressed with a countersunk rigid implant.

Continuing on with our theme from last week of #skullbase reconstruction: Abdominal or thigh fat can be buttressed with a bony septum or prosthesis to keep the fat in place and reconstruct the sella floor. #nsgy #neurosurgery #medtwitter

The site of diaphragm attachment to the tuberculum sella (inset) can be a “blind spot” for surgeons and can tear during tumor removal in the anterior sellar recess. Visit the link below for more on #skullbase reconstruction and CSF leak repair. #nsgy

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

In the telovelar approach (pictured above), removal of the C1 arch can improve visualization of the rostral half of the fourth ventricle, rivaling even that of the transvermian approach. https://t.co/FU5HnTAeSc.
