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 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 ...
17 lis 2019 · The pterion is the H-shaped formation of sutures on the side of the calvarium representing the junction of four skull bones: It is located at the anterior end of the s quamous suture, whereas the asterion is located at the posterior end.
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 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.
30 cze 2020 · Although pterional craniotomy developed by Yasargil in 1975 is the most favored technique to easily approach anterior circulation aneurysms through transsylvian and subfrontal corridors until the present time, 29) temporomandibular joint dysfunction and facial asymmetry due to the iatrogenic trauma of temporal muscle are major drawbacks that can...
Efficient performance of Pterional Craniotomy is important and this video reviews technical nuances and pitfalls for this operative corridor. Starting with patient positioning, we will discuss the incision.
