Surgical correction of enophthalmos and diplopia. A report of 38 cases

Enophthalmos, hypophthalmos, and diplopia are complications of orbital injury. This article reviews the causes of these sequelae, describes a method of strategic implantation of bone grafts to the orbit (and malar bone), and reports the long-term (six months to eight years) results in 38 cases. As a result of bone grafting, all but two patients had a correction of the enophthalmos to within 1 to 2 mm of the opposite eye. Of the 20 patients with diplopia, 15 had correction, and an additional four had an improvement of diplopia so it occurred in only one field of gaze. Of the 22 patients with grafts to the malar bone, 16 were thought to have good to excellent results; however, six developed some degree of reabsorption at the graft site. No patients had any decrease in vision. The advantages and disadvantages of the surgical procedure are described and compared with other methods.
