Abstract:
Objective To study the histologic characteristics of the capsule of breast implant. Methods Four miniprostheses were seperatelly implanted in four positions beneath the panniculus carnosus muscle in 30 rabbits. After 3 weeks, 1, 2, 3, 4, 6 and 12 months, capsular histology examination and the assay of capsular collagen content and type were performed. Results ⑴ Capsule was divided into two layers: the inner layer was dense and the outer loose connective tissues. Collagen component was more, cellular component was less and capsule was thicker (P0.05). ⑵ Capsular collagen content increased gradually in 3 months (P0.05). ⑶Collagen fibers were the most component, reticular fibers were second and elastic fibers were least. After 3 months, elastic fibers decreased, and collagen and reticular fibers became full layer gradually. ⑷ Capsular collagen type I in the capsule was gradually increased and type III decreased before 3 months. There were no significant changes after 3 months. Conclusions Histology of the implant capsule is similar to that of scar and the result of wound healing around implant.
