Orbital Roof Fracture Ct

Coronal slices hard tissue window of the same isolated right orbital roof fracture.

Orbital roof fracture ct.

Communited mildly depressed left orbital roof fracture. Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure. This is reflected in the demographics. Contrast is not needed.

Once the orbital floor is exposed periorbital dissection is performed. It is more prevalent in young men. This frequently causes downward and forward displacement of the globe. 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. Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus. The gold standard for diagnosis of an orbital roof fracture is thin cut coronal ct scanning of the face orbits. Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.

Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. Although sagittal sections are also helpful in some cases the axial images are less so. The following pages provide general information regarding orbital anatomy and dissection.
