Purpose: The best method for reconstructing the fractured orbital floor remains controversial. This article evaluates the usefulness of dehydrated human dura mater for orbital floor reconstruction after facial trauma.
Patients and methods: A retrospective analysis of 55 patients who had undergone surgical repair of orbital fractures was performed. The dura mater was used when the disruption was less than 2 cm in diameter. Fractures were divided into 3 types: type I (blow-out), type II (orbitozygomatic fracture), and type III (midfacial fracture). The patients were followed-up at least 1 year after surgery, and the cosmetic and functional results were reviewed.
Results: A 7% complication rate was noted. No implant migration or infection resulted. One year postsurgery, all patients showed a complete resolution of their diplopia.
Conclusion: The safety and biocompatibility of dehydrated human dura mater support its use in orbital defects less than 2 cm in diameter.
