Orbital Roof Ct

Laterally the lacrimal gland fossa is located medial to the zygomatic process and enlarges the post rim concavity.

Orbital roof ct.

The orbital roof separates the orbit from the anterior cranial fossa which houses the frontal lobes of the brain. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall. Orbital process of the frontal bone orbital process of the zygomatic bone. Superior orbital fissure lies between the lesser and the greater wing of sphenoid.

There are several structures and features regarding the orbital roof that we need to remember. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. The ultimate diagnosis is made by computed tomography ct of the face. It is a thin lamina separating the orbit anteriorly from the frontal sinus and posteriorly from the anterior cranial fossa.

This fissure allows the passage to. Preoperative ct imaging needs to be checked for unusual pneumatization of the orbital roof and possible weak spots. Contrast is not needed. The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits.

Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture. Mild surround frontal lobe edema. While this article will try to list most of the important features of the orbital roof it is by no means comprehensive. This frequently causes downward and forward displacement of the globe.

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. Although sagittal sections are also helpful in some cases the axial images are less so.
