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.
23 lip 2019 · The pterional approach (PA) is a versatile anterolateral neurosurgical technique that enables access to reach different structures contained in the cranial fossae. It is essential for...
1 cze 2001 · The key steps of the pterional approach are positioning, skin incision, interfascial dissection, craniotomy, drilling of the sphenoid wing, and the dural opening. After the bone removal, the pterional approach proceeds with the opening of the sylvian fissure and the basal cisterns.
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.
Download scientific diagram | The pterional approach and its gesture from publication: GRAVEN: a database of teaching method that applies gestures to represent the neurosurgical approach’s...
1 lis 2023 · Anatomically, the pterion can be localized by drawing a line halfway between the lateral orbital ridge and the tragus and a line halfway between the superior temporal line and zygoma (Figure 1A–C). This intersection classically identifies the location of the pterion in most patients.
Structures which are easily accessed through the pterional craniotomy: frontal and temporal opercula, the anterior cranial fossa, orbital gyri, peri- and suprasellar regions and vessels creating the circle of Willis. Anatomy and important anatomical landmarks. Skull bones – frontal, sphenoid, temporal, parietal, zygomatic, zygomatic arch, pterion.
