Why is the suture scar flat and uneven?
1, suture dislocation: After the wound was sutured, the normal skin structure layer was destroyed due to the poor arrangement of skin sutures on both sides and the lack of collagen and elastic fiber tissue during the wound healing process, and a concave scar with large height difference was formed.
2, improper care: there will be a recovery period after the wound is stitched. In the recovery period, the wound will be infected by foreign bodies falling into the wound, exogenous pollution, spicy diet, drinking, etc. In the process of wound healing, scars will proliferate or sag. If the acupuncture wound is exposed to sunlight and ultraviolet rays, it may also lead to scar pigmentation.
3, physical factors: everyone's physical fitness varies widely. If we look at the reaction to the wound, some people are not easy to leave scars visible to the naked eye after skin injury and healing, while others are easy to leave scars after superficial wounds. In the former, if a patient with physique stitches, the scar is generally flat, showing symptoms of pigmentation or loss; People with the latter constitution can easily leave hyperplastic centipede scars after sewing needles.
4. Skin tension: The less or no skin tension on both sides of the suture, the tighter the skin, and the weaker the signal that the body needs to proliferate tissue. Wound healing only needs less tissue proliferation, so the scar after healing is generally flexible flat cable-shaped scar. The greater the skin tension on both sides of the wound suture, the less likely it is to tighten when the wound heals, and the body will receive the signal that it needs to proliferate tissue, and more scar tissue cells will grow to heal the wound. After a long time, it will form a common needle hyperplasia scar.
Methods to prevent suture scar should do the following:
1, the scab of the surgical needle wound should not be uncovered prematurely.
2, avoid eating spicy food such as pepper, onion and garlic after surgery.
3, pay attention to sun protection, newborn skin is delicate, easy to form pigmentation.
4. Don't scratch or rub scars with clothes, and don't scald with water to stop itching.
