“…Early division of middle meningeal artery before passing through FS may be the cause of duplication of foramen spinosum [6,7,8]. Foramen spinosum has been described as an important landmark for microsurgical procedure involving middle cranial fossa particularly when using middle meningeal artery as a donor graft for either internal carotid artery or posterior cerebral artery bypass surgery [9,10]. Hence detailed anatomical knowledge including developmental aspect is really worthwhile as far as neurosurgery and radiology is concerned.…”

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

“…The latter of the aforementioned procedures notes that the MMA trunk must be transected immediately before the bifurcation of its anterior and posterior branch at the location inside the dura and over the FS [16]. The MMA typically bifurcates intracranially; however, in the case presented herein, both the left and right MMA bifurcated extracranially.…”

“…Ustun et al [15] performed an anatomical study through which the spinosum was exposed extradurally in the bypass of the middle meningeal artery (MMA) with the petrous internal carotid artery (ICA) for the treatment of high cervical vascular lesions or tumors occupying the high ICA. Ustun et al [16] also reported an alternative to the anastomosis of the external carotid artery to the posterior cerebral artery (ECA-to-PCA) for the treatment of central vertigo and dizziness, commonly caused by vertebrobasilar insufficiency, by creating a bypass between the MMA and P2 segment of the PCA.…”

Bilateral Duplication of the Foramen Spinosum: A Case Report with Clinical and Developmental Implications

In humans, the foramen spinosum (FS) is located within the sphenoid bone and transmits the middle meningeal artery (MMA). In species that evolutionarily predate humans, the FS exists within the temporal bone, the sphenosquamosal suture, or is absent altogether. It is therefore thought that, during the course of human evolution, the ossification of the posterior aspect of the greater wing of the sphenoid progressively developed around the MMA. The report documents the occurrence of a bilateral duplication of the FS in a male human skull. The report also discusses the clinical and developmental/anthropological significance. Because the foramen spinosum is utilized as a landmark for various surgical procedures involving the middle cranial fossa, the bilateral duplication of the foramen may be disorienting to the surgeon. Similarly, the dynamics of blood flow may be altered due to the bilateral bifurcation of the MMA. Because of the developmental significance of the FS, the occurrence of a bilateral duplication also has important anthropological implications.
