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.
The pterional or frontotemporal craniotomy is the workhorse of the supratentorial approaches. Because of its simplicity, flexibility, efficiency, and familiarity to neurosurgeons, this corridor is the most commonly used surgical route to lesions along the anterior and middle skull base.
The extended pterional corridor can be used to expose parasellar lesions around the circle of Willis and optic apparatus, anterior skull base tumors (including orbital lesions), and interpeduncular and intrasylvian pathologies.
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 ...
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.
7 cze 2019 · Pterional craniotomy is the workhorse approach among cranial operative corridors. It is a highly flexible skull base approach that affords excellent exposure of the anterior cranial fossa,...
16 sty 2024 · Each article was examined according the name of the technique, temporalis dissection technique, craniotomy technique and approach. This systematic review gives an overview of the different techniques and modifications to the pterional craniotomy since it was initially described.
