[Osteoplasty of osseous defects of the frontal bone and orbital roof--indications, technique and results].

From 1972 to 1992, 65 patients with traumatic or postoperative defects of the orbitocranial skeleton were operated on at the department for maxillofacial surgery, University of Essen. Until 1989 alloplastic reconstruction with PMMA implants or autogenous bone grafts of the iliac crest were preferred. Since 1989 we have utilized autogenous calvarial bone grafts (17 cases). CT based models of the defect helped to select calvarial donor sites of appropriate size and contour. The calvarial autografts provided high resistance against resorption. Until now, we have seen no major donor site morbidity. On the whole the results substantiate these autografts to be the superior material for orbitocranial reconstruction.
