Purpose: To describe the use of a novel orbital implant, composed of titanium mesh embedded within porous polyethylene, in the correction of orbital wall fractures. The implant (MEDPOR TITAN, Porex Surgical Inc.) combines the biologically integrative property of a traditional porous polyethylene implant with a radiographically visible titatium core. Methods:Five patients with orbital wall fractures requiring surgical repair to address enophthalmos and/or diplopia underwent the placement of a porous polyethylene implant containing embedded titanium mesh. Clinical outcome, patient tolerance, and visibility of the implant on post–operative computed tomography (CT) scans were assessed. Results: After an average follow up of three months, all five patients achieved satisfactory clinical outcomes based on reduction of enophthalmos and/or diplopia, with no significant adverse reactions to the implants. In all cases the implant was well visualized on post–operative CT scans. Conclusions: Porous polyethylene implants containing embedded titatium mesh combine the advantage of traditional porous polyethylene implants (the capacity for fibrovascular ingrowth) with the additional feature of radiographic density. In this retrospective study, patients tolerated the implant well, and most importantly, precise radiologic localization of the implant was achieved post–operatively due to the visibility of the titanium mesh on CT scan. The MEDPOR TITAN implant is an excellent alternative to a traditional porous polyethylene implant when post–operative imaging of the implant is critical.
