Osteogenesis in a human hydroxyapatite orbital implant 5.5 years after implantation.
PURPOSE: We report the histological findings of a hydroxyapatite orbital implant 5.5 years after implantation. METHODS: The hydroxyapatite orbital implant was excised from the left orbit of a 17-year-old female, and it was decalcified and processed for routine light microscopic evaluation. RESULTS: The implant showed complete fibrovascularization with nearly complete osteogenesis with hematopoiesis. CONCLUSION: Bone may biointegrate throughout the pores of hydroxyapatite orbital implants.
