Abstract

Introduction: Foramen ovale and  Foramen spinosum are important foramina found on the greater wing of the sphenoid. An anatomical study was done to note the size and shape of the Foramen ovale and Foramen spinosum and presence of any bony deformity related to both these foramina.
Materials and Methods: We studied 45 human dried skulls of unknown age and sex and found different shapes of Foramen ovale with variation in size.
Result: We found divided Foramen ovale by a bony bar,confluent foramen spinosum and absent Foramen spinosum.we also noticed a small bony spicule projecting in Foramen ovale and Foramen spinosum. The maximum A-P diameter of F.O on the right side was 5mm to 9mm and 5mm to 8mm on the left side while the transverse diameter of F.S on both the side was 2mm to 4 mm.
Conclusion: These variations may be of clinical and anatomical significance to neurosurgeons and physician particularly in cases of trigeminal neuralgia and diagnostic detection of vascular tumors and aneurysm.
Key words: Foramen ovale, Foramen spinosum, Sphenoid, Trigeminal neuralgia, Skull.
