middle cranial fossa

An irregular depression in the middle of the inner surface of the base of the skull. which houses the temporal lobe of the brain laterally and the hypophysis at its centre. It consists of a central and two lateral portions. The middle cranial fossa is bounded anteriorly by the posterior margin of the lesser wings of the sphenoid bones and the anterior margin of the sulcus chiasmatis, and posteriorly by the superior margins of the petrous parts of the temporal bones and dorsum sellae of the sphenoid bone; laterally, the middle cranial fossa merges with the lateral wall  of the skull on either side. The floor of the middle cranial fossa is comprised of the body and greater wings of the sphenoid bone and the anterior surfaces of the petrous parts of the temporal bones.

INTRODUCTION: Pterion is a significant region which is marked by the junction of frontal bone, parietal bone, squama temporalis and the greater wing of sphenoid bone and forms the floor of temporal fossa. This cranio-metric point on the lateral side of skull is used by neurosurgeons and maxillo-facial surgeons due to its structural and anatomical importance.
The temporalis muscle originates along the temporal line and occupies the temporal fossa before it attaches to the coronoid process of the mandible.
