The patient understood and wanted to proceed with exploration and reconstruction of left orbital floor blowout fracture with split calvarial bone graft. An orbital blowout can occur when an object strikes the orbit with blunt force. An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The orbit or eye socket is the cavity of the skull that holds the eye.

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

A blowout fracture is a break in the floor or inner wall of the orbit or eye socket. Getting hit with a baseball or a fist often causes a blowout fracture.

The floor is likely to collapse because the bones of the roof and lateral walls are robust. Epidemiology the blowout fracture is t.

This is typically caused by a direct blow to the central orbit from a fist or ball. The globe usually does not rupture and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor. This injury is commonly the result of a fist baseball or tennis ball that strikes the eye. There is a history of the orbital entrance being struck by an object usually one larger than the diameter of the orbital opening eg a ball an automobile dashboard or a fist.

The diagnosis of a blowout fracture of the orbital floor is suggested by the patient s history physical examination and radiographs. The patient did have some numbness in the left infraorbital nerve distribution. Orbital blowout fracture or indirect orbital floor fracture. 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.

Bruising and limited eye movements secondary to swelling are common clinical presentations top. 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.
