Creation of a breast shape using an inflatable silicone envelope placed beneath the skin and muscle which is gradually expanded over several weeks by repeated injections of saline.

Tissue expansion is a technique in which skin or other tissue is stretched using inflatable balloons. It can be of particular value in performing breast reconstruction, breast enlargement or treatment of male pattern baldness.

A surgical procedure that involves inserting a balloon-like device (called an expander) under the skin. The expander then slowly secretes liquid into the area to be repaired to actually stretch and expand the skin. This serves the function of "growing" extra skin to repair nearby lost or damaged skin.
