Semiquantitative correction of posttraumatic enophthalmos with sliced cartilage grafts

A simple surgical technique for correcting posttraumatic enophthalmos is described. The steps are as follows: (1) a plaster mold is obtained of the patient's face, (2) wax is added to the enophthalmic eye of the plaster mold until it becomes symmetrical, (3) the quantity of wax is measured, and (4) the same amount of sliced costal cartilage is implanted beneath the periosteum of the extended orbital wall behind the vertical axis of the globe. Using this technique, we have successfully treated six patients with traumatic orbital floor defects without complication. This approach is useful for decreasing the orbital volume using a semiquantitative procedure to estimate the amount of graft material required. In this respect, costal cartilage demonstrates a marked advantage, with stability and cosmetic appearance verified over 12 months of follow-up.
