Abstract

PURPOSE: To evaluate the clinical results of implantation of hydroxyapatite orbital implant in patients with retinoblastoma.
METHODS
The medical records of 31 children who had undergone hydroxyapatite implantation after enucleation or secondary hydroxyapatite implantation, for retinoblastoma from April 1994 to January 2006 were reviewed retrospectively.
RESULTS
The mean age at the time of operation was 64.1 months (range, 1 to 247 months). The mean follow-up period was 35.3 months (range, 3 to 139 months). The diameter of the orbital implants most used was 20 mm (35.4%, range, 16~21 mm). Tutoplast(R), Vicryl mesh(R), and Neuropatch(R) were used as the wrapping materials for hydroxyapatite orbital implant. Of 31 patients (31 eyes), 8 eyes were found to have complications: 6 eyes showed lower lid sagging (19.4%), 1 eye granulation tissue overgrowth (3.2%) and 1 eye conjunctival sac contracture (3.2%). Exposure of the hydroxyapatite orbital implant occurred in 1 eye (3.2%).
CONCLUSIONS
Hydroxyapatite implantation in children with retinoblastoma showed good surgical results and minimal complications.
