The area formed by the junction of the frontal, parietal, temporal, and sphenoid bones is known as the pterion. It has a sutural pattern of fusion of constituent bones that varies. The pterion can be divided into four types based on this. Sphenoparietal, frontotemporal, stellate, and epipteric, according to Murphy. The surgical care of extradural bleeding, aneurysms, and brain tumours in the anterior and middle cranial fossae requires knowledge of the pterion's anatomical placement. The goal of this study is to establish the prevalence of various types of pterion and the location of pterion using anatomical landmarks. Methods and materials- Fifty skulls of undetermined age and sex were used in this study. The anatomical variations of pterion were investigated macroscopically on the skulls. Vernier Calipers were used to measure the distance between the centre of the pterion and the midpoint of the zygomatic arch, as well as the distance between the pterion and the frontozygomatic suture.
The sphenoparietal variant of pterion was shown to be the most common in the
study, followed by the epipteric and stellate varieties, respectively. On the
right side, the distance between the pterion and the back of the
frontozygomatic suture was 3.480.21 cm, while on the left side, it was 3.410.16
cm. On the right side, the distance between pterion and the midpoint of the
upper border of the zygomatic arch was determined to be 4.010.19 cm, while on
the left side, it was discovered to be 3.940.2 cm.
