Orbital Roof Ct

Large round bony mass protruding superior and medially from the left anterior cranial fossa floor.

Orbital roof ct.

Although sagittal sections are also helpful in some cases the axial images are less so. There are several structures and features regarding the orbital roof that we need to remember. While this article will try to list most of the important features of the orbital roof it is by no means comprehensive. Preoperative ct imaging needs to be checked for unusual pneumatization of the orbital roof and possible weak spots.

This frequently causes downward and forward displacement of the globe. It is a thin lamina separating the orbit anteriorly from the frontal sinus and posteriorly from the anterior cranial fossa. The ultimate diagnosis is made by computed tomography ct of the face. Laterally the lacrimal gland fossa is located medial to the zygomatic process and enlarges the post rim concavity.

Orbital process of the frontal bone orbital process of the zygomatic bone. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. The orbital roof largely consists of the orbital process of the frontal bone. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall.

Superior orbital fissure lies between the lesser and the greater wing of sphenoid. Contrast is not needed. The orbital roof separates the orbit from the anterior cranial fossa which houses the frontal lobes of the brain. Mild surround frontal lobe edema.

The orbital roof is composed of the orbital plate of the frontal bone with a small contribution from the lesser wing of the sphenoid at the apex figures 3 4 and 3 5. This fissure allows the passage to.
