Fracture Of The Orbital Roof

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

Fracture of the orbital roof.

When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit. Another mechanism of injury is a blow in fracture where there is an inferiorly directed supraorbital force. Most commonly the inferior orbital wall i e. 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.

This frequently causes downward and forward displacement of the globe. 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. 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. Fractures may be limited to the internal orbital skeleton.

Isolated non displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention. Orbital roof fractures 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. The floor is likely to collapse because the bones of the roof and lateral walls are robust. The following pages provide general information regarding orbital anatomy and dissection.

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. Once the orbital floor is exposed periorbital dissection is performed. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. This type includes blow out and blow in patterns as seen in isolated fractures of the orbital floor medial wall and roof.
