Abstract

A retrospective study was performed on 64 patients who underwent orbital blow-out fracture reconstruction with autogenous or Medpor implant following blunt facial trauma between 1992 and 1997. Hospital records were reviewed especially for preoperative and postoperative diplopia, enopthalmos and extraocular muscle movement limitations between the autogenous material group and Medpor implant group. The autogenous material used was mostly conchal cartilage graft. The average follow-up period was 36 months with a range of 5 to 64 months. There was no significant statistical difference between both groups on incidence of postoperative complications of diplopia, enophthalmos and extraocular muscle movement limitations. Postoperative infection, ectropion, implant extrusion and migration were absent in both groups. The use of Medpor implant for orbital blow-out fracture reconstruction was associated with a low incidence of complication. In addition, the Medpor implant is readily available, easy to use, cut, contour, position, fixate and has no potential for graft resorption, and precludes the need to harvest an autogeneous graft. In conclusion, Medpor is a stable and reliable substitute for autogeneous graft reconstruction of the orbital blow-out fracture.
