When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit.
Orbital roof fracture ct.
The blowout fracture is the most common type of orbital fracture and is usually the result of trauma.
Contrast is not needed.
Orbital blowout fractures are usually the result of a direct blow to the orbit which causes a sudden increase in intraorbital pressure.
Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach.
Communited mildly depressed left 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.
Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit.
Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.
This frequently causes downward and forward displacement of the globe.
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.
It is more prevalent in young men.
The following pages provide general information regarding orbital anatomy and dissection.
This is reflected in the demographics.
