ABSTRACT

Background: The asterion is the junction of the parietal, temporal and occipital bones. The asterion is a surgical landmark to the transverse sinus location which is of great importance in the surgical approaches to the posterior cranial fossa. The sutural morphology was classified into two types, Type I where a sutural bone was present and type II was where sutural bone was absent. The study of asterion may be helpful to ENT and Neurosurgeons.

Materials and Methods: A total of 500 asterion were examined from 250 adult dry skulls. The present study was undertaken in adult south Indian skulls from different regions of south India, from different medical colleges. We have observed different types of asterion like Type I where a sutural bone was present and type II was where sutural bone was absent.

Results: The sutural morphology of the asterion is important in surgical approaches to the cranial fossae. 250 human skulls of known gender (148 male, 102 female) were examined on both sides. Two types of asterion were observed – Type I was 18% in males, 20% in females and in total, Type II was 82% in males, 80% in females and 81% in total.

Conclusion:  Sutural morphology of the asterion in the Indian population does not differ much from that of other populations. These findings useful in surgical approaches and interventions via the asterion.

KEY WORDS: Asterion, Skull, Ocipital, Parital, Temporal.
