Abstract:

Background: Pterion is an anthropometrical landmark situated in the floor of the temporal fossa. The pterion corresponds to the site of the anterolateral fontanelle of the neonatal skull which closes at third month after birth. Pterion has been described as H shaped sutural confluence seen in the norma lateralis of the skull formed by 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. Four different types of pterion i.e. sphenoparietal, frontotemporal, stellate and epipteric have been described in various population groups.

Methods and Results: The present study was undertaken in 150 adult skulls of unknown sexes available in department of Anatomy, Subbaiah Institute of Medical Sciences, Shimoga, to determine the location of pterion and 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 pterion was epipteric pattern (14%) followed by stellate (11%) and frontotemporal (5.67%) types.

Conclusion: These findings will be of importance to anthropologists, anatomists, forensic pathologists and neurosurgeons. 

Key words: Epipteric bones, Pterion, Pterion types.
