Orbital Roof Of Frontal Bone

The floor of the frontal sinus is the roof of the orbit comprised of the frontal bone and lesser wing of the sphenoid.

Orbital roof of frontal bone.

The orbital roof is formed by two bones. Trauma to the frontal bar of the superior orbital rim can cause a buckling of this bone in addition to fractures of the contralateral orbit. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall. The physician wants the projection to demonstrate the frontal bone and place the petrous ridges in the lower one third of the orbits but it has not been determined whiter the patient s cervical spine has been fractured so the patient cannot be moved from a supine position.

Our case showed a well circumscribed osteolytic lesion with granular mineralization and mottled ossified density at the right frontal bone involving the orbital roof which was suspected as atypical intraosseous meningioma and fibrous dysplasia for the first time. The orbital roof largely consists of the orbital process of the frontal bone. The orbital part consists of two orbital plates separated by a gap the ethmoidal notch. The orbital or horizontal part of the frontal bone forms the roof of the orbit and ethmoidal sinuses.

Roof the roof or superior wall of the orbit separates the orbit from the anterior cranial fossa. The name comes from the latin word frons meaning forehead. The orbital plate of the frontal bone forms the anterior aspect of the orbital roof. The nasal part of the frontal bone is located anteriorly between the two orbital parts of the frontal bone forming part of the roof of the nasal cavity.

The frontal bone is a bone in the human skull the bone consists of two portions. The trochlear fovea is a small depression superomedially. Obviously rote memorization is pretty simple since there are only two bones. 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 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. This same patient also requires a frontal projection of the skull. The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa.

These are the vertically oriented squamous part and the horizontally oriented orbital part making up the bony part of the forehead part of the bony orbital cavity holding the eye and part of the bony part of the nose respectively. There are many ways to remember these bones. The largest contributor of the roof is the orbital part of the frontal bone while the small posterior portion is completed by the lesser wing of the sphenoid bone. Orbital process of the frontal bone orbital process of the zygomatic bone.
