Pterional craniotomy was first described by Yasargil in 1975. Pterional craniotomy, also called frontotemporosphenoidal or interfacial pterional craniotomy, is one of the most commonly used approaches in the supratentoral area. Because it is a practical and effective and permits a wide surgical approach, it is frequently used to reach the middle and anterior fossa. The aim of pterional craniotomy is to expose the Sylvian fissure from the basal aspect. The entire inferior frontal gyrus, a portion of the middle frontal gyrus, the entire superior temporal gyrus at the superotemporal section and a portion of the middle temporal gyrus should therefore be exposed. While the frontal and temporal lobes are separated by microsurgical techniques, it should be ensured that the parenchyma does not remain under compression by the bone structures. In this review, we aimed to discuss the tricks of pterional cranitomy stages step-by-step, which are frequently used in the routine practice of all neurosurgeons.
