چکیده
The frontotemporosphenoidal craniotomy, usually denominated pterional craniotomy, was first described by Yasargil in 1975 and is one of the earliest landmarks of the advents of microneurosurgery1-3. This approach enables, specifically, the exposure of the entire frontoparietal operculum4,5, the opening of the entire sylvian fissure6,7 and all anterior cisterns of the encephalon base2,5, which makes both the pterional craniotomy and the transylvian approach the widest used techniques in today’s neurosurgery practice. Over the past decades, the pterional craniotomy has undergone a systematization modified by several authors, what also gave rise to more extended types of craniotomies8,9. Among then, the supraorbital craniotomy10 and the orbitofrontozygomatic craniotomy10-13 stands out. This review offered a detailed description of the technique we use nowadays for this procedure, with modifications arising from its extensive use since its initial proposal, seeking to optimize all its stages, the access and opening of the cisterns, as well as minimize brain retraction.

Effectiveness of Temporal Augmentation Using a Calvarial Onlay Graft during Pterional Craniotomy
Temporal hollowing occurs to varying degrees after pterional craniotomy. The most common cause of temporal hollowing is a bony defect of the pterional and temporal regions due to the resection of the sphenoid ridge and temporal squama for adequate exposure without overhang. The augmentation of such bony defects is important in preventing craniofacial deformities and postoperative hollowness. Te...
متن کاملThe role of pterional keyhole approach in the microsurgical clipping of anterior circulation artery aneurysms: experiences with 26 cases and literature review
Background: Although the pterional approach is commonly used for microsurgical clipping of intracranial aneurysms of anterior circulation, the incision and temporalis muscle dissection impact postoperative recovery and cosmetic outcomes. The pterional keyhole approach offers similar microsurgical corridors with a substantially shorter incision, less muscle dissection, and a smaller craniotomy f...
متن کاملPerspective of the frontolateral craniotomies.
The pterional craniotomy is one of the most frequently surgical approaches used in neurosurgery and currently it has become a mainsteam. It allows excellent microsurgical exposure of anterior and posterior regions of the arterial circle of Willis, supra and paraselar regions, the superior orbital fissure of sphenoid bone, cavernous sinus, orbit, temporal lobe, midbrain and the frontal lobe. Lik...
متن کاملLateral supraorbital approach as an alternative to the classical pterional approach.
OBJECTIVE The standard pterional approach has been used to approach aneurysms of the anterior circulation and the basilar tip, suprasellar tumors, cavernous lesions. The senior author (JH) established a lateral supraorbital approach as an alternative to the pterional approach after continuous trial and error. We describe the techniques of this approach based on clinical experiences. METHODS T...
متن کاملIncidence and clinical significance of frontal sinus or orbital entry during pterional (frontotemporal) craniotomy.
BACKGROUND AND PURPOSE Frontal sinus entry, orbital entry, or both may occur during pterional craniotomy for microsurgical clipping of aneurysms. We sought to determine the incidence and clinical significance of these findings on postoperative CT scans. METHODS Eighty-two postoperative CT scans of the head obtained from 81 patients (64 women, 17 men; age range, 25-80 years) were retrospective...
