Abstract:
PURPOSE: We experienced six cases of late infection of the hydroxyapatite (HA) orbital implant treated with surgical procedures. METHODS: Exposures of the HA and pyogenic granulomas around conjunctival dehiscence helped us to confirm infections of the HA orbital implants. Infections were not controlled by medical therapies so the HA implants were exchanged by silicone implants in all cases. Finally, the silicone implants were replaced by Medpor(R) after the inflammation had been controlled. Dermis fat graft was also performed in two cases due to insufficient conjunctival sac. RESULTS: Infections of HA orbital implants occurred at 62 to 106 months postoperatively. Staphylococcus aureus and Pseudomonas aeruginosa were cultured from removed implants. All cases show successful outcomes during 12 to 42 months after Medpor(R) implantations. CONCLUSIONS: Infections of peg-inserted HA orbital implants occurred after five years due to exposure of HA orbital implants. To replace infected HA implants with Medpor(R) implants is considered a functionally and aesthetically effective therapeutic method.
