Orbital roof fracture ct.

The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits. This frequently causes downward and forward displacement of the globe. This is reflected in the demographics. The following pages provide general information regarding orbital anatomy and dissection.

The ultimate diagnosis is made by computed tomography ct of the face. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. Contrast is not needed.

Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus. Sagittal slices hard tissue window of an isolated right orbital roof fracture. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma.

Communited mildly depressed left orbital roof fracture. Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle. When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit.
