Purpose of review: To review the latest advancements in implant materials for orbital fracture repair, including analysis of the last year in research.
Recent findings: Advances in the manufacture of highly biocompatible alloplastic materials offer an alternative to traditional autologous implants for orbital fracture repair. The emergence of the composite implant offers the stability and strength of traditional titanium mesh, while the porous polyethylene shell allows for greater fibrovascular integration and a potential for decreased risk of postoperative complications. Development of copolymers and biomechanical constructs for the delivery of bone stimulating proteins and stem cells serve to restore orbital volume after fracture repair through stimulation of the patient's own tissue. These recent developments are promising; however, their safety and efficacy have not been verified in humans.
Summary: The appropriate choice of orbital implant for fracture repair ensures appropriate orbital reconstruction in an effort to alleviate diplopia, enophthalmos, orbital dystopia, and extraocular muscle restriction.
