Surgeons use miles and miles sutures of all types: absorbable, non-absorbable, nylon, polypropylene, silk, and other materials, without which we could not repair the skin, subcutaneous tissue, tying vessels, nerves, arteries, veins , and all the various tissues of the body. There are several techniques of suture points with single, double, interrupted, continuous, interrupted sutures, spot pegged and many others.There are those who use other types of wire and other techniques, not to support a face such as during a facelift or for treating a skin wound, but to create real works of art that represent the human body ,as Kumi Yamashita.
