Comparative morphometric study of the sigmoid sinus sulcus and the jugular foramen

Abstract

Objective: To compare the right and left sides of the same skulls as far as the described landmarks are concerned, and establish the craniometric differences between them. Method: We carried out measurements in 50 adult dry human skulls comparing both sides. Results: The sigmoid sinus width at the sinodural angle level was larger on the right side in 78% of the cases and at the level of the digastric notch in 72%. The jugular foramen width was also larger on the right side in 84% of the cases. The sigmoid sinus distance at the level of the digastric notch was larger on the right side in 64% of the cases, and the sigmoid sinus distance at the level of the digastric notch to the jugular foramen was larger on the right side in 70% of the cases. Conclusion: Significant craniometric differences were found between both sides of the same skulls.
