LONG-TERM RESULTS AFTER PRIMARY RESTORATION OF THE ORBITAL FLOOR

It has been possible to follow-up 74 (54%) of the 137 patients who wer e treated for orbital floor fractures in our clinic between 1988 and 1 992. The minimum observation time was 12 months. The results of the or bital reconstruction were analysed on the basis of the postoperative f indings and the advantages of access via a central lower lid incision and the use of allogenic dura mater, were evaluated on the basis of th e functional results. The biocompatibility, stability and ready availa bility of allogenic dura mater all support its use in orbital floor re storation. Nevertheless, the potential problems of CJD transmission ar e discussed.
