Orbital roof fracture definition.

Fractures of the orbital roof typically require a significant amount of force. Getting hit with a baseball or a fist often causes a blowout fracture. Most commonly the inferior orbital wall i e. 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. Clinical diagnosis is based on meticulous examination of the eye including patient vision and palpation of the orbital aperture. Isolated non displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention. The orbital roof forms part of the anterior skull base and is positioned for potential concomitant ophthalmologic and neurologic injury.

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. A crack in the very thin bone that makes up these walls can pinch muscles and other structures around the eye keeping the eyeball from moving properly. A blowout fracture is a break in the floor or inner wall of the orbit or eye socket.
