Left Orbital Floor Blowout Fracture

An orbital blowout can occur when an object strikes the orbit with blunt force.

Left orbital floor blowout fracture.

A blowout fracture is a break in the floor or inner wall of the orbit or eye socket. Inferior blowout fractures involving the floor of the orbit maxillary sinus roof are the most common followed by medial wall blowout fractures. Epidemiology the blowout fracture is t. This is typically caused by a direct blow to the central orbit from a fist or ball.

Orbital blowout fracture or indirect orbital floor fracture. An orbital blowout fracture is a fracture or break in the small bones that make up your 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. The diagnosis of a blowout fracture of the orbital floor is suggested by the patient s history physical examination and radiographs.

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. 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.

Orbital blowout fractures anatomy and mechanism of injury. Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. The patient did have some numbness in the left infraorbital nerve distribution. Orbital floor fractures may result when a blunt object which is of equal or greater diameter than the orbital aperture strikes the eye.

The patient understood and wanted to proceed with exploration and reconstruction of left orbital floor blowout fracture with split calvarial bone graft. 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. The globe usually does not rupture and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor.

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 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. This is a fracture of the paper thin floor of the eye socket with the bony rim surrounding the eye remaining intact.
