Orbital Roof Fracture Ct

Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.

Orbital roof fracture ct.

Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. Coronal slices hard tissue window of the same isolated right orbital roof fracture. Contrast is not needed. Sagittal slices hard tissue window of an isolated right orbital roof fracture.

Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. The ultimate diagnosis is made by computed tomography ct of the face. This is reflected in the demographics. Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus.

The following pages provide general information regarding orbital anatomy and dissection. Once the orbital floor is exposed periorbital dissection is performed. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma. When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit.

Communited mildly depressed left orbital roof fracture. The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits. It is more prevalent in young men.
