Clinical Results of Hydroxyapatite Orbital Implantations using Autologous Sclera as a Wrapping Material

ABSTRACT

PURPOSE: To evaluate the clinical result of hydroxyapatite implantation using autologous sclera as wrapping material. METHODS: From December 2001 to February 2003, we performed 20 cases of hydroxyapatite implantation with autologous sclera as wrapping material. Eyes were enucleated for severe phthisis because evisceration could not provide adequate space for hydroxyapatite implantation or secondary hydroxyapatite implantation after prior evisceration. Postoperative complications were evaluated at postoperative 1 week, 2 weeks, 3 weeks - 1 month, 2 months, 3 months, and every 2 or 3 months thereafter. RESULTS: The mean follow up period was 12.1 +/- 4.52 months (4~18 months). During the follow up period, conjunctival erosions developed in 2 cases, which were controlled by conservative management only. No such postoperative complications as implant exposure, orbital infection, extrusion, inflammatory reaction occured. CONCLUSIONS: Autologous sclera is the suitable wrapping material of hydroxyapatite implant when enucleation is needed in primary surgery for severe phthisis, or for secondary hydroxyapatite implantation after prior evisceration surgery.
