Long-term results after primary restoration of the orbital floor.

It has been possible to follow-up 74 (54%) of the 137 patients who were treated for orbital floor fractures in our clinic between 1988 and 1992. The minimum observation time was 12 months. The results of the orbital reconstruction were analysed on the basis of the postoperative findings and the advantages of access via a central lower lid incision and the use of allogenic dura mater, were evaluated on the basis of the functional results. The biocompatibility, stability and ready availability of allogenic dura mater all support its use in orbital floor restoration. Nevertheless, the potential problems of CJD transmission are discussed.
