Abstract:
PURPOSE: To evaluate the effect of the synthetic bone glass particulate (BG) on the fibrovascular ingrowth into porous polyethylene orbital implant (PP). METHODS: Forty eight rabbits were divided into 4 groups according to the surgical techniques and implanted materials. One eye was enucleated one eye and PP was implanted in group 1, was eviscerated and PP was implanted in group 2, was enucleated and BG, containing 30% by weight synthetic bone glass particulate, was implanted in group 3, and was eviscerated and BG was implanted in group 4. All implants of each group were assessed by histologic study at the first, second, fourth, and eighth weeks postoperatively. The area of fibrovascular ingrowth was calculated by histologic examination. RESULTS: There were no statistically significant differences in the fibrovascular ingrowth among these groups. A greater number of vessels per unit area and matured fibrous tissue was found in the more outer zone at longer time after implantation, but there was not statistically significant difference among the four groups. CONCLUSIONS: On the basis of this study, the synthetic bone glass particulate did not significantly increase the rate of fibrovascular ingrowth into porous polyethylene orbital implant in rabbits.
