Reconstruction of acquired orbital deformity characterized by volume change

Acquired orbital deformity is a common disease in the practice of craniofacial surgery. Defective orbital volume and abnormality of eyeball position are the most important characteristics of pathologic changes. This study includes 87 cases of acquired orbital deformity, which received surgery for volume aberration from 2002 to present. Among them, 73 cases received orbital volume expansion surgery and 14 cases received reduction surgery. Coronal scalp, lower eyelid, or intraoral gingival-buccal incisions were carried out for the approach. In some patients, the original scar around the orbit was chosen for the incision. Operation aims were reduction of orbit and reconstruction of the orbital wall integrity. Operative methods were osteotomy for reduction and implantation of autologous bone or artificial materials. Orbital volume and eyeball position were restored to normal in all patients after the operation, and no serious complications occurred. Treatment of acquired orbital deformity should make restoration of orbital volume as the most important target of therapy. Autologous bone should be the material of first choice, and the selection and amount of implanted material should be decided by the specialty and experience of the physician.
