Left Orbital Floor Blowout Fracture

Orbital blowout fracture or indirect orbital floor fracture.

Left orbital floor blowout fracture.

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. This injury is commonly the result of a fist baseball or tennis ball that strikes the eye. Ct scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor bottom. Typically the floor of the orbit and the medial orbital wall are the bones involved in orbital blow out fractures.

An example of a patient presenting with a right orbital floor blowout fracture. Fractures of the orbital floor are common. Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. This is a fracture of the paper thin floor of the eye socket with the bony rim surrounding the eye remaining 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. The fracture of any of the orbital walls can potentially lead to the widening of the cone that the eyeball sits in. 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. 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.

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. Epidemiology the blowout fracture is t. 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. The orbit or eye socket is the cavity of the skull that holds the eye.

Orbital floor fractures both involving more than 50 percent of the floor s surface. Bruising and limited eye movements secondary to swelling are common clinical presentations top. The floor is likely to collapse because the bones of the roof and lateral walls are robust. 1a with greater displacement and herniation of orbital contents this fracture is much more likely than the other 1b to cause enophthalmos.

Getting hit with a baseball or a fist often causes a blowout fracture. A blowout fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact. Furthermore various complications can be seen with orbital blow out fractures. This is typically caused by a direct blow to the central orbit from a fist or ball.
