Orbital floor blowout fracture radiology. The orbit gives way at its weakest point the orbital floor. Blow out fracture right orbital floor. An orbital blowout can occur when an object strikes the orbit with blunt force. The fracture of any of the orbital walls can potentially lead to the widening of the cone that the eyeball sits in.

When an object hits the orbital bones usually the eye brow and upper cheek bone the force is transmitted to the bones. Any large object with force or speed can cause a blowout fracture. Bruising and limited eye movements secondary to swelling are common clinical presentations top. If the force is great enough the bones buckle and break.

This injury is commonly the result of a fist baseball or tennis ball that strikes the eye. Blowout fractures result from trauma to the orbital bones.

Blowout fractures are caused by increased pressure in the orbit. An orbital blow out fracture occurs when there is a fracture of one of the walls of orbit but the orbital rim remains intact. Typically the floor of the orbit and the medial orbital wall are the bones involved in orbital blow out fractures. Ct scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor bottom.

The classic teardrop sign is due to herniation of soft tissue into the maxillary antrum. A portion of the inferior rectus muscle solid red arrow projects into the maxillary sinus below see normal opposite side broken red arrow. Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. The floor is likely to collapse because the bones of the roof and lateral walls are robust.
