Orbital Roof Fractures

Another mechanism of injury is a blow in fracture where there is an inferiorly directed supraorbital force.

Orbital roof fractures.

Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. This frequently causes downward and forward displacement of the globe. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisions or probably most often via coronal approach.

Usually this kind of injury is caused by blunt force trauma when something hits the eye very hard. Here are types of orbital fractures. The following pages provide general information regarding orbital anatomy and dissection. These occur as a result of direct impact to the face often in car crashes from the face being hit into the steering wheel or an automobile dashboard these fractures occur due to a huge amount of force and because of this force patient also experiences extensive injuries to other facial bones and sometimes even injuries to the brain.

Once the orbital floor is exposed periorbital dissection is performed. Any of the bones surrounding the eye can be fractured or broken. Orbital roof fractures are more common in childhood as the frontal sinus has not yet pneumatised therefore all posterior force to the superior orbital rim is transferred to the anterior cranial base. An orbital fracture is when there is a break in one of the bones surrounding the eyeball called the orbit or eye socket.

The floor is likely to collapse because the bones of the roof and lateral walls are robust. Most roof fractures are associated with other orbital fractures and result from significant head trauma as a high degree of force is required to fracture this portion of the orbit. When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit. Orbital roof fracture icd 801 01 etiology.

Isolated orbital roof fractures in adults are uncommon comprising 12 19 of all orbital wall fractures.
