Abstract

PURPOSE
We evaluated clinical results and incidence of exposures of orbital implants according to operative methods (enucleation or evisceration) and types of orbital implants. METHODS: We retrospectively reviewed the charts of 222 patients who underwent hydroxy apatite or Medpor(R) implantation after enucleation or evisceration and were followed up for more than 3 months from July, 1992 to November, 2001 at department of ophthalmology, Busan Paik hospital. RESULTS: In 222 eyes of 222 patients, who underwent hydroxyapatite and Medpor(R) implantaion, the exposure of implants occurred in 21 eyes (9.5%). In these cases, the exposure of implants occurred in 16 (12.8%) of 125 eyes with hydroxyapatite implantation and 5 (5.2%) of 97 eyes with Medpor(R) implantation. The exposure of implants occurred in 6 (7.1%) of 84 eyes after enucleation and in 15(10.8%) of 138 eyes after evisceration. The exposure of implants occurred in 12 (12.2%) of 98 eyes that used standard evisceration and in 3 (7.5%) of 40 eyes that used modified evisceration. CONCLUSIONS: The exposure of Medpor(R) implants was less than that of hydroxyapatite implants. But, it was influenced by types of orbital implants as well as operator and operative skill. There are few differences of exposure rate between the modified evisceration and enucleation.
