Fracture Of The Orbital Roof

The following pages provide general information regarding orbital anatomy and dissection.

Fracture of the orbital roof. Orbital roof fractures are frequently associated with a high energy impact to the craniofacial region and displaced orbital roof fractures can cause ophthalmic and neurologic complications and occasionally require open surgical intervention. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. Sagittal slices hard tissue window of an isolated right orbital roof fracture. Coronal slices hard tissue window of the same isolated right orbital roof fracture.

A 22 year old man who was assaulted with a baseball bat suffered an operative orbital roof blow in fracture and fractures of the medial and lateral orbital walls right frontal bone and sinus and. This type includes blow out and blow in patterns as seen in isolated fractures of the orbital floor medial wall and roof. Most commonly the inferior orbital wall i e. Isolated non displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention.

Fractures of the roof of the orbit are typically associated with trauma to the forehead frontal bone are are often extensions of superior orbital rim fractures. The floor is likely to collapse because the bones of the roof and lateral walls are robust. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. Fractures may be limited to the internal orbital skeleton.

Fractures of the orbital roof typically require a significant amount of force. An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall typically resulting from impact of a blunt object larger than the orbital aperture or eye socket. Another mechanism of injury is a blow in fracture where there is an inferiorly directed supraorbital force. This frequently causes downward and forward displacement of the globe.
