Orbital Roof Fracture Ct
Coronal slices hard tissue window of the same isolated right orbital roof fracture.
Orbital roof fracture ct. Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. Once the orbital floor is exposed periorbital dissection is performed.
Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle. Contrast is not needed. Communited mildly depressed left orbital roof fracture. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma.
Sagittal slices hard tissue window of an isolated right orbital roof fracture. This frequently causes downward and forward displacement of the globe. The ultimate diagnosis is made by computed tomography ct of the face. The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits.
This is reflected in the demographics. When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit. The following pages provide general information regarding orbital anatomy and dissection.
