Orbital Roof Of Frontal Bone

The floor inferior wall is formed by the orbital surface of maxilla the orbital surface of zygomatic bone.

Orbital roof of frontal bone.

Orbital process of the frontal bone orbital process of the zygomatic bone. The orbital roof is formed by two bones. 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. The lesser wing of the sphenoid bone forms the posterior aspect of the orbital roof.

Superior orbital fissure lies between the lesser and the greater wing of sphenoid. 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. The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa. This fissure allows the passage to.

Isolated non displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention. Obviously rote memorization is pretty simple since there are only two bones. The orbital plate of the frontal bone forms the anterior aspect of the orbital roof. Orbital roof fracture icd 801 01 etiology.

The roof superior wall is formed primarily by the orbital plate frontal bone and also the lesser wing of sphenoid near the apex of the orbit. There are many ways to remember these bones. Preoperative computed tomography ct scan of the tumor in the frontal bone and orbital roof.
