Objective:

The aim of the study is to identify morphological differences and the location of pterion in the male population of Indore.

Methods:

53 consecutive male cerebral CT scan images (aged 25 to 45 with no cranio-facial fracture were included)with a slice thickness of 0.5 mm were chosen . The dataset was obtained from the SIEMENS Somatom Scope with 16 slices. The images were loaded into the imaging programed PACS (WFM), where they were examined using three-dimensional (3D) Multiplanar reconstruction viewers. Measurements were made as a horizontal and vertical distance from the centre of the pterion to the posterolateral edge of the frontozygomatic suture in lateral projections of the skull in the Frankfurt plane. Vertical distance between the pterion's centre and the superior border of the zygomaticotemporal arch. Additionally, the morphological types were identified.

Results:

Right side pterion types were 94.3% sphenoparietal and 5.6% frontotemporal, whereas left side pterion types were 90.5% sphenoparietal, 3.7% frontotemporal, 1.8% epipteric, and 3.7% stellate. On the right side, the average frontozygomatic measurements were 22.3 ±2.2 mm and 12.5 ±2.2 mm, respectively. The same measurements were 22.7± 2.5 mm and 12.26± 2.2 mm on the left side, respectively. On the right and left sides, the mean zygomaticotemporal measures were 34.5 ±2.9 mm and 34.4 ±2.5 mm, respectively.

Conclusion:

The study offers helpful information regarding the positioning of the pterion for secure neurosurgery procedures using the pterion. Additionally, the radiologist can distinguish between a fracture line and normal morphological variety thanks to their understanding of the various morphological kinds of pterion.
