摘要：Back ground: The foramen spinosum is one of important foramina located in the base of the skull on the greaterwing of sphenoid bone situated posteriorlaterally to the foramen ovale, therefore it could be identified both fromthe exterior and interior of the skull base, externally the foramen spinosum pierces the spinous process of thesphenoid bone at its apex or medial aspect. Foramen spinosum transmits the passage of the middle meningealartery, parietal trunk of the middle meningeal artery and posterior trunk of the middle meningeal vein to themiddle cranial fossa.Materials and Methods: Total 300 skull were used for this study. The shape of foramen spinosum and diameter ofit recorded with vernier calipers.Results: Foramen spinosum found as round shape in 58%, oval shape in 38% and irregular in 4%. The maximumdiameter of foramen spinosum was 2.77+0.97mm and 2.03+0.56mm was minimum in females, in males maximumdiameter was 2.95+0.56mm and 1.52+0.82mm as minimum. The knowledge of foramen spinosum is great helpfulfor neurosurgeons.Conclusion: The round shape was found in more number of skulls and very few were irregular shape. The knowledgeof foramen spinosum help to cranial surgeons as it is transmitting middle meningeal artery.
