The foramen spinosum was given its name because of its proximity to the spine of the sphenoid bone. It is an opening located in the greater wing of the sphenoid bone as part of the middle cranial fossa. Vascular and nervous structures emerge through this foramen, including the middle meningeal artery and the meningeal branch of the mandibular nerve, or the nervous spinous, which originates in the sensory portion of the trigeminal nerve. The venous component, which is the middle meningeal vein that connects the cavernous sinus with the pterygoid venous plexus, also passes through this foramen. The present study aims to find morphological variations and morphometric measurements of foramen spinosum. Materials and Methods: The present study conducted with 96(192 sides) adult dry skull. All the skulls were examined carefully and identified the gender and separated, we have observed right and left sides of all the skulls to find out the foramen spinosum. We have observed the morphological shapes round, oval and irregular. We measured Length, width of foramen and calculated Area. All the measurements were expressed in the form of Mean+SD and tabulated. Results: The present study carried out with 96(192 sides) adult dry skulls. The round shape foramen spinosum found in 62.5% sides, oval was in 32.3% sides and irregular was 5.2% sides. We have measured the Length(mm), it was 2.64+0.52mm, Width(mm) was 2.12+0.26 mm and Area(mm2) was 4.39+0.11 mm2 and range was 1.22 - 8.38 mm2. Conclusion: The results of foramen spinosum may be helpful to neurosurgeons, it may also useful in practice of forensic medicine and anthropology
