The use of computer-generated three-dimensional models in orbital reconstruction.
In this paper we describe the application of three-dimensional (3D) imaging and computer-generated models in the management of orbital deformity. The technique was found to be particularly useful in posttraumatic deformity and fibrous dysplasia involving the orbit. Further application was found in cases of radiation hypoplasia, high facial cleft, and facial atrophy. Funding restrictions necessitate appropriate selection of cases when using new and expensive 3D imaging rather than traditional and less expensive methods. To remain within a realistic budget only those patients who will clearly benefit from the third dimension compared with traditional methods of assessment and management should be selected. These include patients requiring precise reduction or secondary reconstruction in which there is a matched normal anatomical component for comparison. This application is also only beneficial where the planned reconstruction is dimensionally stable.
