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.
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.
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.
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.
1 sty 2012 · There is also evidence of right parietal craniotomy. Coronal CT image ( b ) in a different patient shows a skull-fixated screw fiducial marker ( arrow ). Axial T1 MRI with contrast ( c ) shows three skull-based fiduciary markers ( arrow ) for guiding radiation therapy of a left frontal lobe lesion, which was also resected.
1 wrz 2012 · This review intended to describe in a didactic and practical manner the frontotemporosphenoidal craniotomy, which is usually known as pterional craniotomy and constitute the cranial approach...
