Orbital Roof Ct

Superior orbital fissure lies between the lesser and the greater wing of sphenoid.

Orbital roof ct.

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. Preoperative ct imaging needs to be checked for unusual pneumatization of the orbital roof and possible weak spots. Large round bony mass protruding superior and medially from the left anterior cranial fossa floor.

Contrast is not needed. The orbital roof largely consists of the orbital process of the frontal bone. This fissure allows the passage to. 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 gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits. The ultimate diagnosis is made by computed tomography ct of the face. Orbital process of the frontal bone anterior superior portion lesser wing of the sphenoid postero medial portion inferior wall.

This frequently causes downward and forward displacement of the globe. Although sagittal sections are also helpful in some cases the axial images are less so. Mild surround frontal lobe edema. Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture.

It is a thin lamina separating the orbit anteriorly from the frontal sinus and posteriorly from the anterior cranial fossa. 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.
