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.
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 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.
Pterion is a specific area located on the side of the bony skull in the temporal region, where four bones meet. These bones include the frontal bone, parietal bone, greater wing of the sphenoid bone, and the temporal bone.
The frontotemporal, so-called pterional, approach has evolved with the contribution of many neurosurgeons over the past century. It has stood the test of time and has been the most commonly used transcranial approach in neurosurgery.
20 lut 2024 · The brain consists of billions of neurons (nerve cells) that communicate through intricate networks. The primary functions of the brain include processing sensory information, regulating bodily functions, forming thoughts and emotions, and storing memories.
