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.
13 gru 2020 · Pterion is the name given to the region on the lateral aspect of the skull where four bones are joined: Parietal bone; Squamous part of temporal bone; Front bone; Greater wing of sphenoid bone; Pterion is a point of clinical significance – the skull is very thin at this point.
The pterion is the H-shaped region where four cranial bones meet: the squamosal portion of the temporal bone, the greater wing of the sphenoid bone, and the frontal and parietal bones.
Anatomical structures exposed through the pterional approach include the sellar and parasellar lesions, the optic nerves and chiasm, the Sylvian fissure, the frontal, temporal, and parietal operculum, the temporal lobe, and basal cisterns. There are many variants of the pterional craniotomy.
