A breast implant is a prosthesis used to change the size, form, and texture of a woman’s breast; in plastic surgery, breast implants are applied for post–mastectomy breast reconstruction; for correcting congenital defects and deformities of the chest wall; for aestheticbreast augmentation; and for creating breasts in the male-to-female transsexual patient.


There are three general types of breast implant devices, defined by their filler material: saline solution, silicone gel, and composite filler. The saline implant has an elastomer silicone shell filled with sterile saline solution; the silicone implant has an elastomer silicone shell filled with viscous silicone gel; and the alternative composition implants featured miscellaneous fillers, such as soy oil,polypropylene string In surgical practice, for the reconstruction of a breast, the tissue expander device is a temporary breast prosthesis used to form and establish an implant pocket for emplacing the permanent breast implant. For the correction of male breast defects and deformities, the pectoral implant is the breast prosthesis used for the reconstruction and the aesthetic repair of a man’s chest wall (see: gynecomastiaand mastopexy). 


A breast implant is a medical prosthesis that is placed inside the breast to augment, reconstruct or create the physical form of the breast. The outer layer of breast implants is made of firm silicone. The inside of the implant is filled either with salt water (saline solution), silicone gel, or a composite of alternative substances. Makers of breast implants say they should last for at least ten years.
