[Reconstruction of the orbit floor using a resorbable polydioxanone (PDS degree) cup. Analysis of a series of 71...

A 71 patients series is presented, concerning primary orbital floor reconstruction by a polydioxanone cup (PDS degree) which has been used for five years. The technical data and surgical procedure are exposed. No infection either intolerance manifestation has been observed until the materiel was resorbed. Two early displacements of the implant are reported, due to a technical fault during the insertion of the cup. Only one late enophtalmy was observed for a patient with a large orbital floor defect. The loss a the rigidity of the polydioxanone seems to be relatively fast (probably 2-3 months) and leads to contraindicate its use in cases of large osseous traumatic defects. In all other cases, this surgical technique seems to be very useful.
