Objective To study silicone gel leaking in the rats implanted silicone gel filled protheses.Methods 40 female SD rats were divided into A,B,C,D?4 groups.Intact silicone filled protheses were implanted in a separate subcutaneous pocket under the dorsal skin in group A,rupture silicone gel filled protheses in group B and saline filled protheses in group C.The same operations were done on group D,but nothing were placed in the pocket and skin wound were then sutured.After an implantation period of six months,capsuler histological examination and blood silicone level test were performed.Results Histologic aspect of the fibrous capsule showed no difference in group A,B and C.Leaking silicone gel droplets were discovered in fibrous capsule of group B.The blood silicone levels showed no difference in group A,B,C,and D.Conclusion Histological response of rats to silicone gel implant have no significant difference from the response to saline filled implant.Leaking silicone gel had no effect on the capsule development and the blood silicone level. |
