Abstract
Abstract: :
Purpose: Various materials have been used to wrap spherical orbital implants following enucleation or evisceration to potentially reduce complications and improve motility. We sought to determine the safety and efficacy of unwrapped spherical orbital implants for enucleation and evisceration surgery. Methods: We retrospectively reviewed all patients of one surgeon (JDP) undergoing orbital implantation for enucleation, evisceration, and secondary implantation from October 1999 to October 2001. Charts were reviewed for type of surgery, use of a wrapping material, type and size of implant, and complications. Results: Forty-five patients underwent 28 eviscerations, 15 enucleations, and 2 secondary implantions. Forty-four patients underwent implantation without wrapping material. Twenty-three patients received polymethylmethacrylate, 15 received porous polyethylene, 6 received coraline hydroxyapatite, and 1 received bovine hydroxyapatite. Mean implant diameter was 19.1 mm (range 16 to 22 mm). Mean follow-up was 11 months. There were no complications of implant extrusion, exposure, infection, or migration. Conclusion: Unwrapped spherical orbital implants appear to be associated with a low rate of extrusion or other implant-related complications.
