Tissue expansion is a Plastic Surgical procedure in which silicone balloons (expanders) are inserted, and then serially inflated with saline.
Tissue expansion has been used in many clinical situations including:
Both immediate and delayed reconstruction. The expander is the actual breast prosthesis. The expander can be over inflated then deflated to reproduce a natural looking breast. Single or two stage operations are possible.
The effect of tissue expansion is especially useful in delayed breast reconstructions. The extra skin which is achieved replaces that lost at the time of the mastectomy.
