Giant Conjunctival Granuloma Developed after Drilling of the Hydroxyapatite Orbital Implant

We experienced a patient who developed protrusion of prosthesis due to giant conjunctival granuloma around screw type sleeve without dehiscence or infection of conjunctival wound 1 year after hydroxyapatite drilling. We performed excision of granuloma with mitomycin-C soaking, and then obtained an excellent cosmesis without recurrence.
