Orbital floor fracture, also known as “blowout” fracture of the orbit. A “blowout Fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact.The adult orbital floor is composed of the maxillary, zygomatic, and palatine bones (see image below). The orbital floor is the shortest of all the walls; it does not reach the orbital apex, measures 35-40 mm, and terminates at the posterior edge of the maxillary sinus.These fractures may be asymptomatic and can be observed or cause problems with double vision, or a change in the position of the eyeball, and require surgical repair.

Where is an orbital floor fracture?
Commonly, the bone at the bottom of the orbit (orbital floor) is fractured as it is the thinnest bone. Due to more elasticity in their bones, children are susceptible to a special type of orbital fracture called a “trapdoor” or “white-eye fracture”.
What causes orbital floor fracture?
Orbital floor fractures may result when a blunt object, which is of equal or greater diameter than the orbital aperture, strikes the eye. The globe usually does not rupture, and the resultant force is transmitted throughout the orbit causing a fracture of the orbital floor.
How are orbital floor fractures treated?
Most orbital floor defects can be repaired with synthetic implants composed of porous polyethylene, silicone, metallic rigid miniplates, Vicryl mesh, resorbable materials, or metallic mesh. Autogenous bone from the maxillary wall or the calvaria can be used, as can nasal septum or conchal cartilage.
How do you repair an orbital floor fracture?
Repair of an orbital floor fracture involves bridging of the floor defect using one of the various biomaterials. More commonly, titanium meshes, porous polyethylene sheets, or autologous bone grafts. Titanium meshes and bone grafts are radiopaque.
How long does it take for an orbital floor fracture to heal?
Conclusions: Orbital floor strength is regained 24 days after repair. The authors now let patients resume normal activities approximately 3 weeks after uncomplicated orbital floor fracture repair. This is one of many clinical factors in assessing the return to normal activities.
