Tissue expansion is a procedure used to “grow” extra skin for use in reconstructing various areas of the body. Through the process, a balloon is inserted under the skin, near the area to be repaired. Over the course of several weeks, or even months, the balloon is injected with a saline solution, which causes the skin to slowly stretch and grow. This new, excess skin is then moved to the desired location.
This technique is often used in breast reconstruction, but is also beneficial in scalp reconstruction and the treatment of burns, trauma and disease.
