Ocular Orbital Floor Blowout Fracture

Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact.

Ocular orbital floor blowout fracture. An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The release of this force may protect the eye from more serious injury. Getting hit with a baseball or a fist often causes a blowout fracture. A softball to the eye a tumble to the floor a gunshot wound while hunting or a wayward fist at a local watering hole all might send a patient to the trauma center with an orbital or ocular injury.

Commonly the bone at the bottom of the orbit orbital floor is fractured as it is the thinnest bone. A blowout fracture is a break in the floor or inner wall of the orbit or eye socket. Due to more elasticity in their bones children are susceptible to a special type of orbital fracture called a trapdoor or white eye fracture. Most blowout fractures are caused by an impact to the front of the eye from something bigger than the eye opening such as a baseball a fist or an automobile dashboard.

This is typically caused by a direct blow to the central orbit from a fist or ball. The floor of the eye socket ruptures or cracks resulting in a small hole in the eye socket s floor which can trap some parts of the eye muscles and its surrounding. Etiology fractures of the orbital floor are common. Direct orbital floor fracture if an orbital rim fracture extends into nearby parts of the eye socket floor both the rim and the socket floor are fractured.

Most blowout fractures are caused by an impact to the front of the eye from something bigger than the eye opening such as a baseball a fist or an automobile dashboard. The floor is likely to collapse because the bones of the roof and lateral walls are robust. This injury is commonly the result of a fist baseball or tennis ball that strikes the eye. Epidemiology the blowout fracture is t.

This is a fracture of the paper thin floor of the eye socket with the bony rim surrounding the eye remaining intact. An orbital blowout can occur when an object strikes the orbit with blunt force. A blowout fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact. It is estimated that about 10 of all facial fractures are isolated orbital wall fractures the majority of these being the orbital floor and that 30 40 of all.

In patients with facial fractures 20 to 25 percent include orbital involvement at some level. Direct orbital floor fracture if an orbital rim fracture extends into nearby parts of the eye socket floor both the rim and the socket floor are fractured. 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 most commonly the inferior orbital wall i e.
