Orbital roof reconstruction using porous polyethylene sheet with embedded titanium.

Calvarial defects, including the orbital roof defect that occurs after trauma or oncologic resection, require immediate reconstruction to avoid complications such as enophthalmos, diplopia, and transmission of the cerebral pulse to the eye. In these cases, autologous bone grafts or various alloplastic materials have been used.Between January 2010 and December 2010, 5 patients underwent surgery for orbital roof reconstruction using porous polyethylene sheet with embedded titanium, which was developed for reconstruction of inferomedial wall of the orbit. One patient underwent surgery because of tumor excision; the other patients, because of trauma. Two patients had intracranial hemorrhage and 3 patients had a defect in the supraorbital rim. We reconstructed the supraorbital rim and the orbital roof using a combination of calvarial bone graft and the porous polyethylene sheet with embedded titanium. The sheet was bended and trimmed according to the shape of the orbital defect, and it was fixed on the remaining adjacent bone using a microplate.There were no complications during the follow-up period. The patients were satisfied with the external appearance.In conclusion, the orbital roof reconstruction using porous polyethylene sheet with embedded titanium was an easy and a time-efficient procedure with satisfactory results.
