Analysis of complications after orbital reconstruction with Medpor implantation for the orbital blowout fracture

Abstract

Objective To analyze the causes of complications after orbital reconstruction with high density porous polyethylene (Medpor) for the repair of orbital blowout fracture. Methods A retrospective analysis of patients with orbital blowout fracture treated with Medpor in our department was carried out. Results In 232 cases after postoperative follow up of 3 months, the visual function decreased significantly in 2 cases, endophthalmos was undercorrection in 7 cases, residual diplopia was observed in 2 cases and implant displacement was detected in 1 case. Conclusion There are many kinds of complications after orbital reconstruction with Medpor implantation for blow-out fracture of orbital floor wall, such as vision loss, enophthalmos, diplopia exacerbation, infection, and so on. The causes are related to the degrees of fracture, location, doctor's skill and experience, and postoperative functional training. The key points for successful repair of orbital fracture include effective prevention, correct analysis of causes and timely treatment.
