Posttraumatic enophthalmos is caused by enlargement of the orbital volume, mainly owing to missed diagnosis or incorrect reconstruction.6 Therefore, the treatment of these patients must focus on the repair of the anatomical size of the orbit. In the delayed repair of orbital trauma, it is, however, extremely difficult to reconstruct the original size of the orbit because of bone remodeling and scarring. Fine adjustments that must be performed intraoperatively remain a major challenge to virtually any surgeon. Three typical surgical methods are used to treat enophthalmos: osteotomies of the orbital walls (often in combination with navigation surgery devices), insertion of alloplastic implants, or insertion of autologous bone. In patients with osteotomies, the repair of the orbit with the original bone is often not feasible because of resorption. Even with the help of a navigational system, bony gaps cannot be avoided and must be closed with the insertion of implants. In addition, navigation surgery is still an expensive method and is not available to every surgeon. Several alloplastic materials, including titanium, silicone, Teflon (E.I. du Pont de Nemours and Company, Wilmington, Delaware), polytetrafluorethylene, and methylmethacrylate polymers, have been used for volume and structural augmentation in the orbit. Use of these synthetic materials, however, is more likely to result in infection, extrusion, and the initiation of an inflammatory response, including fistula and cyst formation, compared with autogenous grafts.15,16 Autogenous grafts are commonly harvested from the skull, rib, or iliac crest. However, endochondral bone, such as from the rib or iliac crest, is partially resorbed over time; postoperative pain and local hematoma are significant complications at the donor site. In membranous bone, such as calvarial bone, the donor site morbidity is minimal. The procedure described is a simple method for obtaining a graft, which is said to have a low rate of postoperative absorption.17,18 A big disadvantage, however, is the limited malleability of the calvarial bone, which makes restoration of the correct anatomical situation of the orbit more difficult. For optimal restoration of the orbit, the grafts should be placed behind the eyeball.6,7 To achieve an optimal result, some surgeons19 insert multiple layers of bone grafts in the posterior third, whereas others5 prefer to cut the graft into sections and plate the pieces in the desired shape. To our knowledge, the outcomes of these procedures have not been published. In our hands, these techniques showed some disadvantages. It turned out to be especially difficult to perform fine adjustments using multiple layers of compact bone fixed to each other with screws or to bring the implants into the desired form by using plates on different, sometimes small, bone grafts.
