It seems a new silicone dressing has been developed that could “reduce scars caused by surgery.” It is stretched over the wound and remains there for eight weeks, “reducing the tension on the skin that leads to scarring.” Usually stitches are used to hold the two tissue edges together and the inflammation around the area produces collagen which help the wound heal but these layers aren’t put back in the same way and thus “stand out from the surrounding skin, resulting in scarring.” Then, once the stitches are removed, the tissue edges are pulled in different directions by the “taut surrounding skin.” This can result in the spreading of scar tissue which thickens and raises it.
A staggering 90 percent responded to a survey saying that they were not happy with the scar that remained from a surgery they had undergone within the last six months to a year. This new dressing hopes to rectify this, making many more people happy with their scar.
The dressing was developed at Stanford University by scientists who first tested it on pigs who have very similar skin to humans. They found that it resulted in a six-fold reduction in how much scarring is caused by a one-inch incision. Next, nine women following a tummy-tuck surgery were experimented on with half being treated with the new dressing and the other half left to heal without it. The treated area “had significantly reduced scarring.” In addition, researchers see the potential for patients with unsightly scars to have surgery to remove them with the new technique as a healing process.
