Scar tissue is a fibrous connective tissue that replaces a normal skin after any kind of injury. It can be found after injury, cut, or surgery on any tissue in the body including skin and internal organs. Scarring is a natural part of healing process in which the body puts together new fibers.
Scar tissue is made of collagen protein. It is thicker and pale, as it has a limited supply of blood. Scarring starts after injury by fibroblast growth, a process that begins with a reaction to the clot. Over the time the scar becomes thick and stiff. The scar tissue fiber composition is different and is of inferior quality than that of normal collagen. Scars in the skin are less resistant to sunlight, and hair follicles and sweat gland do not grow back within scar tissue. Scar can be of different types like hypertrophic, keloid or atrophic scar.
Scar Tissue Causes
Scars on the skin are caused due burns, cut, insect bites or wound after accident, or due to acne infections. Chicken pox or small pox leave deep scars which takes a lot of time to go off. Scars can also form in internal organs. Scar formation takes place in heart muscle, during myocardial infarction. In kidney, scars are formed due to urinary tract infection, glomerulosclerosis or in diseases such lupus or diabetes. Epidural fibrosis is the formation of scar tissue near the nerve root. It causes lot of pain. Brain scars are caused due to head injury or when brain is subjected to any sort of immense physical shock or due to long depression.
Scar Tissue Symptoms
Scar tissues symptoms depend on the part of the body where it is formed. Scar due to injury causes pain. Abdominal adhesions scars due to appendicitis, Crohn’s disease or ulcerative colitis causes pain, nausea, vomiting, abdominal distention, and an increase in pulse rate. Scar tissue over reproductive organs prevents pregnancy. Excess scar tissue on nerve root can cause impaired nerve physiology, pain or even paralysis.
Scar Tissue Treatment
Alpha hydroxy acids, trichloroacetic acid and phenol peels are common chemicals used in the treatment of scar. Salicylic acid is commonly used to treat acne scars. Cyclopentasiloxane, dimethicon, retinyl palmitate, tocopheryl acetate and lecithin are some of the chemicals used for treatment of scars. They strengthen the walls of individual cells and capillaries, and trigger the proliferation and soften the skin. Corticosteroid injections help flatten and soften scars.
2. Laser treatment
It is most commonly used treatment for hypertrophic and keloids scars. This therapy smoothen the skin by heating up and redistributing collagen and cause minimal damage to skin.
Nanotechnology not only gets rid of the brain scar tissue, but it also encourages brain nerve re-growth.
Laminotomy is a surgical procedure designed to remove painful scar tissue. Cosmetic or plastic surgery can be done to remove scars.
Scars can be easily treated, but the length of time required varies from person to person and environmental condition.
