Orbital Roof Fracture Ct

Communited mildly depressed left orbital roof fracture.

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. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma. Although sagittal sections are also helpful in some cases the axial images are less so. Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.

The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. Once the orbital floor is exposed periorbital dissection is performed. The following pages provide general information regarding orbital anatomy and dissection.

When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit. Coronal slices hard tissue window of the same isolated right orbital roof fracture. 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.

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. This is reflected in the demographics.
