Orbital Roof Ct

This frequently causes downward and forward displacement of the globe.

Orbital roof ct.

Mild surround frontal lobe edema. 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. There are several structures and features regarding the orbital roof that we need to remember.

It is separated posteriorly from roof of orbit by superior orbital fissure and separated from floor of orbit by inferior orbital fissure the lacrimal foramen which transmits the recurrent meningeal branch of the ophthalmic artery is located anterior to the superior orbital fissure along the superior edge of the lateral wall. While this article will try to list most of the important features of the orbital roof it is by no means comprehensive. This fissure allows the passage to. Although sagittal sections are also helpful in some cases the axial images are less so.

Large round bony mass protruding superior and medially from the left anterior cranial fossa floor. Laterally the lacrimal gland fossa is located medial to the zygomatic process and enlarges the post rim concavity. 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.

Superior orbital fissure lies between the lesser and the greater wing of sphenoid. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall. Preoperative ct imaging needs to be checked for unusual pneumatization of the orbital roof and possible weak spots. Contrast is not needed.

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. Orbital process of the frontal bone orbital process of the zygomatic bone.
