13 maj 2024 · The pterional or fronto-temporo-sphenoidal approach is one of the most frequently performed neurocranial craniotomy/craniectomy approaches and allows access to numerous important supratentorial anatomical substrates of vascular and neoplastic pathology.
Sagittal oblique illustration (b) and three-dimensional volume rendering (c) demonstrate pterional (frontotemporal) craniotomy, the preferred approach for Circle of Willis aneurysms or cavernous sinus lesions.
The type of craniotomy performed depends on the location of the lesion, with the goal being to minimize brain retraction so as to reduce the risk for perioperative intracerebral hemorrhage. Main types of craniotomy: pterional (frontosphenotemporal) subtemporal; anterior or posterior parasagittal; median or lateral suboccipital . Normal imaging ...
1 wrz 2012 · The key steps of the pterional approach are positioning, skin incision, interfascial dissection, craniotomy, drilling of the sphenoid wing, and the dural opening.
The pterional craniotomy for MCA aneurysms extends more distally along the Sylvian fissure than for anterior communicating artery aneurysms. This factor is especially applicable for long M1 segments harboring posteriorly projecting aneurysms.
1 sty 2020 · The frontotemporal, also called pterional, approach is one of the most commonly used approaches by neurosurgeons to access the sphenoid wing, suprasellar and sellar regions, cavernous sinus, and upper clivus. This approach is indicated in: • Aneurysms clipping the anterior and posterior circulation (upper basilar and its proximal branches) •
Pterional craniotomy is a work horse approach among cranial approaches. This video reviews the extended pterional craniotomy with some modifications to expand its operative reach through the sub frontal corridor.
