Abstract
To investigate the extent and pattern of fibrovascular ingrowth of porous silicone sphere implants compared to porous polyethylene implants. Experimental porous silicone sphere implants and porous polyethylene implants were implanted in the left socket of 20 New Zealand white rabbits after enucleation. Fibrovascular ingrowth and maturation was evaluated at 4 weeks and 8 weeks after implantation by histopathologic examination and scanning electron microscope. At 4 weeks after surgery, porous polyethylene implants showed deeper fibrovascular ingrowth than porous silicone sphere implants; 42.4% versus 34.2% of radius of the implants respectively ( = 0.047). However there was no significant difference in the depth of fibrovascular ingrowth between the two groups at 8 weeks after implantation, although porous polyethylene implants showed deeper fibrovascular ingrowth than porous silicone sphere implants; 71.6% versus 63.6% ( = 0.102). Porous silicone orbital implants demonstrated a comparable extent of fibrovascular ingrowth to that for porous polyethylene implants. Therefore, this new porous silicone sphere implant may be a good candidate to substitute for current porous implants at a lower cost.
