What part of the orbital is involved in a blowout fracture?
An orbital blowout fracture of the floor of the left orbit. Direct trauma to the eye socket. In pure orbital blowout fractures, the orbital rim (the most anterior bony margin of the orbit) is preserved, while with impure fractures, the orbital rim is also injured.
What causes an orbital blowout fracture?
Blowout fractures result from trauma to the orbital bones. When an object hits the orbital bones (usually the eye brow and upper cheek bone) the force is transmitted to the bones. If the force is great enough, the bones buckle and break. Any large object with force or speed can cause a blowout fracture.
Does orbital blowout fracture need surgery?
Orbital Blowout Fractures Often, the fracture occurs in the orbital floor or medial wall. While some orbital fractures do not require surgery, large fractures or fractures that cause enophthalmos or diplopia do necessitate a surgical procedure.
Is orbital blowout fracture serious?
Eye injuries resulting from orbital blowout fracture This is a very serious eye injury requiring hospitalization, bed rest, bilateral patching of the eyes, and sedation. This condition usually resolves itself within a few days.
What force can cause a blowout fracture?
Blow-out fractures, or fractures of the orbital wall, are a result of either increased intraorbital pressure from blunt force leading to compression of the orbital tissue and subsequent fracture or blunt force to the orbital rim resulting in buckling of the orbital floor.
What is 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.
What is the effect of a orbital floor fracture?
General treatment Immediately after an orbital floor fracture, the affected eye may have impaired motility, resulting in double vision. The eye may be proptotic or enophthalmic, depending on the amount of edema (causing proptosis) and the size of the fracture (larger fractures leading to enophthalmos).
Is a blowout fracture a medical emergency?
The majority of blow-out fractures do not require surgical intervention. Patients with orbital blow-out fractures who have minimal displacement, no diplopia, and no entrapment can be safely discharged home. All patients should be evaluated by an ophthalmologist within one week of the event.
How do you fix a blowout fracture?
What can be done for a simple blowout fracture?
- ice to decrease swelling.
- decongestants to aid in the drainage of blood and fluid accumulating in the sinuses.
- avoidance of nose blowing to prevent pressure from propelling the sinus contents into the orbit.
- oral steroids in some cases to decrease swelling and scarring.
What is the treatment for orbital blowout fracture?
The objective of fracture treatment is to reduce displaced soft tissues and restore the preinjury anatomic contour and volume of the bony orbit. Surgery and observation are the main treatment options.
How long does a blowout fracture take to heal?
Around 3 to 4 weeks after the injury, the formation of new mature bone starts. This can take a long time – several years, in fact, depending on the size and site of the fracture. However, there are cases wherein bone healing is not successful, and these cause significant health problems.
Is a blowout fracture an emergency?
Can a blowout fracture heal itself?
Treatment Options The occurrence of a blowout fracture in and of itself is not necessarily an indication for surgical repair. Patients without significant displacement of the eyeball within the boney eye socket or without entrapped muscle within the fracture site usually do not require surgical repair of the fracture.
How long does orbital blowout fracture take to heal?
Although eye socket fractures can be dangerous, most people recover well. If you went into the surgery with double vision, it may last as long as two to four months after surgery. If it doesn’t go away after four to six months, you may need eye muscle surgery or special corrective glasses.
How do you fix a 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.
What is a blowout fracture?
A blowout fracture is a break in the floor or inner wall of the orbit or eye socket. 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. Getting hit with a baseball or a fist often causes a blowout fracture.
