Hypergranulation tissue may be treatable through a number of methods, including silver nitrate, vapor-permeable dressings and surgical lasers, as detailed on Podiatry Today. Hypergranulation tissue sometimes occurs on healing wounds and requires medical treatment to allow the wound to heal properly.
Normal granulation tissue is new tissue with capillaries that forms over a wound and allows epithelial tissue to grow over the healed wound site, according to Skilled Wound Care. Hypergranulation tissue, on the other hand, is as an overgrowth of granulation tissue that grows out above the height or past the edge of the skin surrounding the wound.
Applying silver nitrate to hypergranulation tissue on a wound cauterizes the excess tissue, causing it to stop growing and shrivel. The excess tissue is then removed, allowing the wound to heal normally, as shown on Skilled Wound Care.
Using a vapor-permeable dressing to the wound, such as one made from breathable foam, may help to treat hypergranulation tissue, notes Podiatry Today. The dressing should be applied using a light amount of pressure.
Surgical lasers effectively remove hypergranulation tissue while cauterizing small blood vessels. Lasers offer more precise cauterization than silver nitrate, allowing the surgeon to leave healthy cells untouched. Podiatry Today also suggests hypertonic NaCl dressings. These salt-based dressings help stop the growth of hypergranulation tissue by pulling excess fluid away from the wound and letting it dry out.
