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.

The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa. Orbital process of the frontal bone orbital process of the zygomatic bone. The orbital plate of the frontal bone forms the anterior aspect of the orbital roof. 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.

The frontal bone is involved in the three regions of the head such are. Preoperative computed tomography ct scan of the tumor in the frontal bone and orbital roof. The orbital roof is formed by two bones. 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. The floor inferior wall is formed by the orbital surface of maxilla the orbital surface of zygomatic bone. 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. 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. There are many ways to remember these bones. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall.
