Breast, the main function of which is breastfeeding, has been a complementary element of the female sex outside the reproductive system throughout human history. Each race has a unique breast shape, the width, color and size of the nipples differ from each other. Sometimes developmental and sometimes familial characteristics do not develop sufficiently at the end of adolescence and normally may remain smaller. After breastfeeding, breasts may shrink or breast tissue may decrease and cause a hollow appearance. In people with obesity problems, it may become deformed and sag in the breasts after diet or stomach reduction surgery. There are two safe surgical procedures for women with such problems; Breast augmentation with silicone prosthesis and breast augmentation with oil graft injection. Breast augmentation with silicone prosthesis Silicone prostheses consist of hard silicone on the outside and dense fluid silicone on the inside. Although different brand prostheses are offered in our country, I use products with FDA and CE certificates for my patients. Silicone prostheses are divided into 2 according to their shape; Damla (Anatomical) prosthesis; It has a flat bottom and has an upper surface that increases from top to bottom. It has a more dense hard structure compared to round prosthesis. In the decollete part, it is not as prominent as a round prosthesis. It is more suitable for natural breast image. Round prosthesis; It has a hemispherical shape and has a softer consistency. It is more useful in defining the decollete area.
