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.
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 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.
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...
19 sty 2023 · In women, the pelvic floor muscles support the urethra, vagina, and anal canal. The weakening of these muscles can result in a loss of structural support to these organs – presenting as: Urinary incontinence
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.
