Orbital Floor Reconstruction using custom-made implant with screw fixation

Dr. Avi Toeg, Oral & Maxillofacial senior staff specialist, The Baruch Padeh medical center.
A 24-year-old patient suffered from a blowout fracture of his left orbital floor, following facial trauma.
He required reconstruction of the floor. To prevent increased or reduced volume of the orbit, which would result in enophtalmus or exophthalmos.
The conventional treatment to restore the orbital floor using autogenic bone, titanium or vicryl mesh, or other materials. There is difficulty in exactly restoring the shape of the orbit due to the complex anatomy and the danger of damage to the optic nerve.
The implant was designed using the shape of the orbit of the other eye which was intact.
The surgery was made with general anesthetic, and was completed in 20 minutes, using the custom-made implant with screw fixation. Conventional surgery would last more than an hour.
The low dose post-op CT shows excellent adaptation, and the patient has full function and aesthetics two years later.
