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 extended pterional approach is defined as a standard pterional craniotomy supplemented and expanded by osteotomy along the lateral sphenoid wing to the level of the superior orbital fissure, and; drilling along the roof of the orbit to flatten its surface and expand the subfrontal trajectory.
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 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 ...
7 cze 2019 · Pterional craniotomy: This model provides a 3D rendition of a standard pterional craniotomy corridor and includes all major neurovas- cular elements and bony anatomy.
1 wrz 2012 · To describe a modified pterional craniotomy technique and that mobilizes part of the sphenoid wing and the pterion in a block with the temporalis muscle to enhance cosmetic results.
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) •
