DRAINING CUTANEOUS FISTULA ASSOCIATED WITH INFECTION OF HYDROXYAPATITE ORBITAL IMPLANT

The implantation of an orbital hydroxyapatite implant was complicated by conjunctival dehiscence, cutaneous fistula formation, and infection with Staphylococcus aureus. Pathologic examination of the sphere 2 ye ars after its implantation revealed reduction in the size of the impla nt, peripheral lamellar bone formation and central necrosis. This is t he first report of this constellation of complications with hydroxyapa tite spheres positioned in the orbit. The 2-year interval between impl antation and removal of the sphere is the longest reported in a case w ith histopathologic analysis.
