Orbital Roof Of Frontal Bone

A c preoperative ct of the head showed a 5 3 7 4 cm sized well demarcated osteolytic frontal lesion with mottled ossified density which also infiltrated the orbital roof.

Orbital roof of frontal bone.

There are many ways to remember these bones. The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa. Isolated non displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention. The frontal bone creates the smooth curvature of the forehead and protects the frontal lobe of the brain especially the ethmoid bone s horizontal plate known as the cribriform plate which allows the olfactory nerve bundles to pass through its perforated surface and bring the ceiling of the nasal cavity its sense of smell.

Fractures of the roof of the orbit are typically associated with trauma to the forehead frontal bone are are often extensions of superior orbital rim fractures. Orbital process of the frontal bone orbital process of the zygomatic bone. The orbital roof is formed by two bones. Obviously rote memorization is pretty simple since there are only two bones.

Superior orbital fissure lies between the lesser and the greater wing of sphenoid. The orbital plate of the frontal bone forms the anterior aspect of the orbital roof. This fissure allows the passage to. Preoperative computed tomography ct scan of the tumor in the frontal bone and orbital roof.

The lesser wing of the sphenoid bone forms the posterior aspect of the orbital roof. The frontal bone is involved in the three regions of the head such are. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall.
