[Morphological study of capsules formed around various breast endoprostheses]

Silicone implants used in mammaplasty are often associated with constrictive capsule fibrosis, leading to induration and deformation of the prosthetic organs. In connection with this, there has been developed and is currently successfully applied in the clinical practice of the A. V. Vishnevsky Institute of Surgery an original method of mammary gland endoprosthesis with oily implants. The objective of this work was to make a comparative study of the late results of mammaplasty based upon the morphologic study of capsules formed around silicone and oily implants, removed during secondary surgical interventions. The dynamics of capsule formation around temporary organic glass endoprostheses has also been studied. The results showed that implantation of silicone prostheses results in a formation of a rough thick capsule, an active inflammatory reaction in the surrounding tissues and the development of constrictive fibrosis. Implantation of a temporary organic glass endoprosthesis that is filled with oil at the second stage of the operation, is followed by a thin capsule formation without signs of inflammation. The stability of the capsule structure up to 3 years has been noted. On the whole, this prosthesis provides a good cosmetic effect during long time after mammaplasty.
