摘要：Background: Pterion is an anthropometrical landmark situated in the floor of the temporal fossa. The pterioncorresponds to the site of the anterolateral fontanelle of the neonatal skull which closes at third month afterbirth. Pterion has been described as H shaped sutural confluence seen in the norma lateralis of the skull formedby the frontal and parietal bones superiorly and the greater wing of sphenoid and squamous temporal inferiorly.It’s location is approximately 4 cm above zygomatic arch and 3.5 cm behind the frontozygomatoc suture. Fourdifferent types of pterion i.e. sphenoparietal, frontotemporal, stellate and epipteric have been described invarious population groups.Methods and Results: The present study was undertaken in 150 adult skulls of unknown sexes available indepartment of Anatomy, Subbaiah Institute of Medical Sciences, Shimoga, to determine the location of pterionand define its type. In the present study, the sutural pattern of pterion was based on Murphy’s classification.Sphenoparietal was the commonest type (69.33%) of pterion. The second commonest type of pattern of pterionwas epipteric pattern (14%) followed by stellate (11%) and frontotemporal (5.67%) types.Conclusion: These findings will be of importance to anthropologists, anatomists, forensic pathologists andneurosurgeons.
