Skin expanders (PDF) are primarily utilized for reconstructive purposes. They are implanted to grow excess tissue for the treatment of defects, which were, for example, caused by burns or accidents.
An expander is inserted like an implant, but only temporarily. Initially, an expander is just an empty shell with a built-in or remote valve. This shell is gradually filled through the valve with saline solution. Through the slow expansion of the expander, the patient's skin tissue expands over a period of several weeks or months. Additional tissue is obtained, which can be transplanted to a different location on the body of the patient.
In Dieburg, Germany, POLYTECH Health & Aesthetics manufactures skin expanders in different sizes and shapes for a variety of uses.
