Orbital Roof Ct

Mild surround frontal lobe edema.

Orbital roof ct.

The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits. Contrast is not needed. Orbital process of the frontal bone orbital process of the zygomatic bone. Laterally the lacrimal gland fossa is located medial to the zygomatic process and enlarges the post rim concavity.

The orbital roof separates the orbit from the anterior cranial fossa which houses the frontal lobes of the brain. The ultimate diagnosis is made by computed tomography ct of the face. This frequently causes downward and forward displacement of the globe. The orbital roof largely consists of the orbital process of the frontal bone.

This fissure allows the passage to. Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture. Preoperative ct imaging needs to be checked for unusual pneumatization of the orbital roof and possible weak spots. There are several structures and features regarding the orbital roof that we need to remember.

Large round bony mass protruding superior and medially from the left anterior cranial fossa floor. Although sagittal sections are also helpful in some cases the axial images are less so. It is a thin lamina separating the orbit anteriorly from the frontal sinus and posteriorly from the anterior cranial fossa. 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.

While this article will try to list most of the important features of the orbital roof it is by no means comprehensive. 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.
