Abstract:

The greater wing of sphenoid bone has multiple foramina. The consistent foramina of middle cranial fossa are Foramen Ovale, Foramen Rotundum and Foramen Spinosum. Foramen Vesalius (FV) and Canaliculus Innominatus (CI)are inconsistent. So the present study was conducted to investigate the presence and absence of FV and CI in dry human skulls and to study the location and frequency of both foramina in 30 human skulls available in the Department of Anatomy. The skulls were examined from external and internal aspects. In the present study three skulls reported to have FV and two skulls have CI out of thirty skulls. Two skulls out of three skulls contained FV on right side only and one skull has FV on both sides.Two skulls have CI in which one has bilateral presentation and one has single opening on right side.Knowledge about the characteristics of FV and CI and its frequency is not only important for anatomist but equally essential for clinicians who approach middle cranial cavity for various procedures.
