What is scar hyperplasia

Scar hyperplasia is a common problem, especially for people with scar-prone constitution. After scars appear, scar hyperplasia is very likely to occur. In addition, if the wound is not treated well after it occurs, it will also lead to the occurrence of scar hyperplasia. Below, we will introduce to you in detail the characteristics and treatment methods of scar hyperplasia!

1. What is scar hyperplasia

Scar hyperplasia Scar hyperplasia, also known as keloid, is caused by excessive proliferation of fibrous connective tissue. Keloids are raised skin surfaces that appear as tumor-like hyperplasia with a smooth surface, rosy and shiny color, and often contain dilated capillaries. The skin lesions extend outward from the edges and become crab-like in shape. The skin lesions vary in size and shape, and are hard, like cartilage. The subjective symptoms are mostly itchy, painful, or burning sensations.

2. Characteristics of scar hyperplasia

In the early stage, local scars swell, become congested and hardened, and most of them will not cause serious functional disorders. At this time, the surface, middle, bottom and basal layers of hypertrophic scar tissue are:

1. The surface layer is a layer of atrophic epithelial cells.

2. The middle layer is vascularized and infiltrated with inflammatory cells.

3. The bottom layer contains fewer collagen fibers and a large amount of connective tissue hyperplasia.

4. The basal layer is not adhered to the deep tissue and can promote low contractility.

3. Treatment methods for scar hyperplasia

Local subcutaneous injection: For scar hyperplasia, the drug injection is directly injected into the scar subcutaneously for treatment. The main ingredient of this drug is steroids, which can fight inflammation and dissolve inflamed tissue. This is currently the simplest and most effective treatment for scar hyperplasia.

Surgical treatment: Surgical treatment of scar hyperplasia is relatively suitable for scars with larger areas. The treatment is relatively difficult and the clinical effect is generally good. There are three common methods: facial scar excision plus skin grafting, skin flap method, and simple excision and suture method.

Chemical peels are used for mild or superficial peels and use trichloroacetic acid or alpha-hydroxy acid to gently remove the top layer of skin cells. For common scars, doctors usually perform trichloroacetic acid peeling. These peels are very effective in curing scar hyperplasia.
