title: Hospital Universiti Sains Malaysia experience in orbital floor reconstruction: autogenous graft versus Medpor.
abstract: OBJECTIVE
  A normally restored orbital structure after reconstructive surgery would accelerate the return of orbital function. The aim of the present study was to compare the outcomes of 2 orbital implants: autogenous grafts and porous polyethylene (Medpor).
  
  
  METHODS
  A longitudinal study was conducted of all patients who had undergone orbital floor reconstruction using an autogenous graft or Medpor. The study participants were divided into 2 groups, and the postoperative outcomes were assessed clinically.
  
  
  RESULTS
  Of the 26 patients, 14 (53.0%) had undergone surgery with an autogenous graft and 12 (46.2%) with Medpor. Postoperatively, no diplopia in the primary gaze was noted in any patient. However, down gaze and peripheral diplopia was found in 11.5% and 26.9% in the autogenous group and in 3.8% and 26.9% in the Medpor group, respectively (P = 1.24). Enophthalmos was present in 11.4% of the autogenous graft group and 15.3% of the Medpor group (P = .465). The Hess chart findings were abnormal in 11.4% of both groups (P = .062). Restriction of movement was observed in 1 patient (3.8%) from the autogenous group and 7.7% of the Medpor group (P = .574).
  
  
  CONCLUSIONS
  Orbital floor reconstruction using an autogenous graft or Medpor showed comparable results.
