5 cases of Infected Hydroxyapatite Orbital Implant

ABSTRACT

PURPOSE: To describe the rare condition of an infection of hydroxyapatite orbital implant in five patients who had undergone seemingly uncomplicated evisceration and implantation of hydroxyapatite orbital implant. METHODS: The infection of hydroxyapatite orbital implant developed from 6 months to 6 years (mean 3 years 4months) after evisceration and from 3months to 6years (mean 2years 7months) after drilling. In all cases, lid swelling, conjunctival injection and implant exposure were observed. In 3 cases, the hydroxyapatite orbital implant was removed and Medpor(R) implantation was done. In 2 cases, the hydroxyapatite orbital implant was removed and dermis fat graft was done simultaneously. RESULTS: In all five cases the inflammation signs disappeared and conjunctival sac was well formed for artificial eye fitting after treatment. CONCLUSIONS: We experienced 5 cases of infected hydroxyapatite orbital implant, and treated them successfully.
