Clinical Experiences of Hydroxyapatite Implant

ABSTRACT

The hydroxyapatite has been used as an orbital implant for reconstruction after enucleation or evisceration. It has been known to be a biocompatible and nontoxic implant with good fibrovascular ingrowth, few postoperative complications, excellent prosthesis motility, and good cosmesis. We performed 36 cases of hydroxyapatite implantation with enucleation or evisceration from July 1992 to August 1994. The mean follow-up period was 7.4 months(range, 4 to 13 months). There were nine cases of implant exposure. three cases of peg extrusion, three cases of superficial conjunctival wound dehiscence, and one case of granulation tissue overgrowth. There was no infection of implant. Improving the postoperative results and reducing the postoperative complications, it requires proper surgical techniques including the selection of adequate implant size and good doctor-patient relationship.
