Orbital Roof Of Frontal Bone

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 roof of frontal bone.

The lesser wing of the sphenoid bone forms the posterior aspect of the orbital roof. There are many ways to remember these bones. This fissure allows the passage to. The frontal bone is involved in the three regions of the head such are.

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

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

The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa. Superior orbital fissure lies between the lesser and the greater wing of sphenoid. The orbital roof is formed by two bones.
