The extended pterional craniotomy must be tailored to the specific underlying pathology. The following steps describe the general principles of this approach, whereas the other relevant chapters review tailored exposures and intradural dissection via this route.
1 kwi 2007 · The key steps of the pterional approach are positioning, skin incision, interfascial dissection, craniotomy, drilling of the sphenoid wing, and the dural opening.

1 sty 2020 · The frontotemporal, also called pterional, approach is one of the most commonly used approaches by neurosurgeons to access the sphenoid wing, suprasellar and sellar regions, cavernous sinus, and upper clivus. This approach is indicated in: • Aneurysms clipping the anterior and posterior circulation (upper basilar and its proximal branches) •
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.
The midline suboccipital craniotomy is the preferred mode of exposure for the majority of vermian, posterior inferior pontine and medullary, foramen magnum, midline cerebellum, and pineal regions.
