Background and Objectives : Among the various alloplastic materials which are used in reconstruction of the traumatic orbital defects, porous polyethylene sheets (PPSs) are increasingly used due to their improved biocompatibility, easy malleability, and minimal complication. We report our experience with PPSs in reconstruction of the traumatic orbital defects.
Material and Methods : PPSs (0.85 mm or 1.5 mm) were used in 23 patients with significant traumatic orbital defects. Twenty patients were treated for orbital floor defects, 2 for medial wall defects, and 1 for both floor and medial wall defects. Their surgical results and postoperative complications were studied. Their mean follow-up period was 18 months.
Results: Postoperatively, diplopia or limitation of eye movements were resolved in 11 of 17 patients and enophthalmos in 6 of 9 patients. No patients had induced diplopia or exacerbation of preoperative symptoms. There were no complications like graft extrusion, infection, clinically detectable graft distortion, or resorption.
Conclusion: PPS appears to be an excellent material for reconstruction of the traumatic orbital defects.
