    Abstract:
    PURPOSE: To compare wrapped and polymer-coated hydroxyapatite implants in children undergoing primary enucleation with no adjuvant therapies. DESIGN: Retrospective, interventional cohort study. PARTICIPANTS: All children undergoing primary enucleation without adjuvant therapies between 1999 and 2009 at a tertiary pediatric cancer hospital. METHODS: Review and analysis of patient records. MAIN OUTCOME MEASURES: Implant exposure, extrusion and migration, socket contracture, and formation of pyogenic granuloma. RESULTS: Sixty consecutive patients undergoing primary enucleation with no adjuvant chemotherapy or radiation with follow-up of at least 12 months were included. Retinoblastoma was the diagnosis in 59 eyes (98.3%). Median follow-up was 3.6 years (range, 1.0-9.3 years). Two implant sizes were used: 20 mm in 47 patients (78.3%) and 18 mm in 13 patients (21.7%). Overall, 52 patients (86.7%) had an event-free recovery. Polymer-coated hydroxyapatite implants (43/60, 71.7%), when compared with wrapped ones (17/60, 28.3%), had a trend toward greater event-free recovery (odds ratio [OR], 1.6; 95% confidence interval [CI], 0.3-7.7) and lower exposure rate (OR, 2.1; 95% CI, 0.4-10.5). CONCLUSIONS: The use of polymer-coated hydroxyapatite implants is associated with favorable outcomes in the pediatric population. Despite observed complications, long-term implant retention is possible in most children.
