title: Efficacy of Iliac Crest vs. Medpor in Orbital Floor Reconstruction.
abstract: OBJECTIVE
  The present study is to compare the effectiveness of iliac crest graft and medpor implant, for repairing traumatic orbital floor defects.
  
  
  METHODS
  A total of 20 patients were included in the study. Autogenous iliac crest graft and medpor implant was used in 10 patients of the each group. Patients were evaluated for the presence or absence of diplopia, enophthalmos, infraorbital nerve paresthesia, and ocular motility disorders. Surgical indications for orbital exploration included entrapment of orbital tissues, large orbital defect (greater than 50% of the orbital floor or more than 8 mm), or orbital floor defects with involvement of other zygomaticofrontal complex fractures.
  
  
  RESULTS
  All patients were successfully treated by restoration of the orbital wall continuity. Follow-up was done at 1-12 weeks. One patient had postoperative infection. There was no graft extrusion.
  
  
  CONCLUSIONS
  Both the groups showed satisfactory results, but group II was better than group I, as there was no donor site morbidity. Porous polyethylene (Medpor) is a biocompatible and high-density polyethylene implant. It is well tolerated by surrounding tissue, and its porous structure is rapidly infiltrated by host tissue. It is a highly stable and somewhat flexible porous alloplast that has rapid tissue in growth into its pores.
