Abstract:
AIM: To study the causes of pyogenic granuloma after hydroxyapatite(HA) orbital implants.METHODS: HA orbital implants (250 cases) in our hospital (68 pegged implants) were reviewed.All patients were followed up from 18 months to 10 years. Implants were removed after medical therapy which was proved to be ineffective.RESULTS: Ten of 250 cases of HA orbital implants developed pyogenic granuloma. Pyogenic granuloma occurred in 1 unpegged implants patient and 9 patients after pegging and drilling of HA implantation over 4～7 years. The pyogenic granulomas were not controlled by medical therapy effectively. Implants were removed in 9 cases except 1 case denied removing and continued medical therapy.CONCLUSION: Pyogenic granuloma was serious complication that occurred after HA orbital implants. Partial vascularization, implant exposure, xenogenic sclera implant, pegging and drilling of HA implantation are risk factors that affect the development of pyogenic granuloma.Pyogenic granuloma hasn't relation with implanted peg material. Pyogenic granuloma denotes the potential implant infection, and all implants should be removed finally.
