Introduction: The pterion corresponds to the site of anterolateral fontanelle of the neonatal skull which closes at third month after birth. In the pterional fractures the anterior and middle meningeal arterial ramus ruptures commonly which results in extradural hemorrhage. Pterional approach is most suitable and minimally invasive approach in neurosurgery.

Materials and Methods: The present study was carried out on the pterion of 36 dry adult skulls of known sex from department of anatomy GMC Aurangabad Maharashtra.

Results: The mean and standard deviation of the distance between the centre of pterion to various anatomical landmarks. The distance between Pterion- frontozygomatic (P-FZ) suture 29.81±4.42mm on right side, 29.81±4.07mm on left side; Pterion-Zygomatic arch (P-Z) 37.16±3.77mm on right side, 37.56±3.71mm on left side, Pterion-asterion (P-A) 89.73±6.16mm on right side, 89.46±6.35mm on left side; Pterion-external acoustic meatus (P- EAM) 53.40±7.28mm on right side, 53.57±6.73mm on left side, Pterion- Mastoid process (P-M) 80.35±3.44mm on right side, 80.96±3.79mm on left side and Pterion- Pterion (P-P) 194.54±16.39mm were measured.

Conclusion: The data constructed in the present study will be of immense importance while performing pterional approach surgeries in Indian population.

KEY WORDS: Pterion, Fontanelle, Neonatal Skull, Extradural Hemorrhage, Pterional Approach.
