Left Orbital Floor Blowout Fracture

Ct scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor bottom.

Left orbital floor blowout fracture.

The diagnosis of a blowout fracture of the orbital floor is suggested by the patient s history physical examination and radiographs. Bruising and limited eye movements secondary to swelling are common clinical presentations top. Epidemiology the blowout fracture is t. 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 fracture is a fracture or break in the small bones that make up your eye. The patient did have some numbness in the left infraorbital nerve distribution. 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. The orbit or eye socket is the cavity of the skull that holds the eye.

Orbital floor fractures may result when a blunt object which is of equal or greater diameter than the orbital aperture strikes the eye. 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. Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. 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.

Blowout fractures of the orbit most frequently affect the middle third of the orbit where the orbital walls are the thinnest. Getting hit with a baseball or a fist often causes a blowout fracture. Orbital blowout fractures anatomy and mechanism of injury. 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. Inferior blowout fractures involving the floor of the orbit maxillary sinus roof are the most common followed by medial wall blowout fractures. The floor is likely to collapse because the bones of the roof and lateral walls are robust. 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.

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. Orbital blowout fracture or indirect orbital floor fracture. Clinically showed the patient with enophthalmos.
