Abstract
Ablative surgery for tumors of the globe and its adnexal structures is frequently the cause of major orbitofacial deformity. Radiotherapy compounds the problem because it suppresses skeletal growth in the growing patient and induces a contraction of the remaining soft tissues in the orbit. Goals for reconstruction in these patients include the restoration of orbital structures to allow the fitting of an ocular prosthesis and the correction of distorted orbitofacial relationships. The authors present a series of 53 patients (mean age, 29 years; 28 male) who were treated over the past 18 years by composite reconstruction of the post-tumoral anophthalmic orbit. The follow-up ranged from 5 months to 18 years (mean, 7.75 years). Four patients were treated primarily (immediate reconstruction after tumor ablation), and 49 were treated secondarily (mean oncological follow-up since ablative surgery, 14.8 years). Twenty-eight patients underwent orbital enucleation (including three bilateral cases), 23 underwent orbital exenteration, and two underwent evisceration. Forty-two patients received radiotherapy, including 20 enucleation patients, 15 exenteration patients, and seven others in whom details of primary therapy were incomplete. A staged reconstruction was undertaken in each case; it considered, in turn, the bony orbital volume (orbital remodeling and cranial bone grafts), orbital contents (implant, temporalis muscle transposition, cranial bone grafts, and dermafat grafts), conjunctival sac (mucosal and skin grafts), ocular prosthesis, eyelids (local flaps and skin grafts), and additional procedures to restore orbitofacial symmetry. The authors conclude that the long-term results of post-tumoral orbital reconstruction are favorable, and they particularly recommend the use of autogenous tissues in irradiated orbits. (Plast.
