[Osprovit: hydroxylapatite ceramic for the reconstruction of blow-out fractures of the orbital floor].

Abstract

Common polymeric implantations, in use for the orbital floor reconstruction, form usually a surrounding fissural space and thus tend to dislocations. With the conservative methods that have been available up to now, the Dura Mater cannot be definitely sterilised so that a transmission of a virus may be possible, which causes the Creutzfeld-Jacob Encephalopathy. As an appropriate alternative-both for primary and secondary reconstruction of the orbital floor-an implantation of dense hydroxylapatite ceramics (Osprovit), anatomically shaped, is indicated. According to x-ray techniques of evaluation it presents itself without artifacts. It does not dislocate because it coalesces physiologically with the surrounding tissues and because of its biocompatibility, it is undoubtedly suitable as a permanent implantation. Post-operative examinations of 20 patients showed neither enophthalmus nor diplopia. All patients were without subjective symptoms.
