Orbital Roof Fracture Ct

This frequently causes downward and forward displacement of the globe.

Orbital roof fracture ct.

Although sagittal sections are also helpful in some cases the axial images are less so. Communited mildly depressed left orbital roof fracture. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus.

Coronal slices hard tissue window of the same isolated right orbital roof fracture. Once the orbital floor is exposed periorbital dissection is performed. 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.

Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. 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. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach.

Sagittal slices hard tissue window of an isolated right orbital roof fracture. The ultimate diagnosis is made by computed tomography ct of the face. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma.
