What are the symptoms of scar hyperplasia after skin grafting?

Generally speaking, skin grafting refers to skin grafting surgery. Skin grafting surgery involves transplanting autologous or allogeneic skin tissue to a skin defect area to address the issue of skin loss. The general reference price for skin grafting surgery is 8000-20000 yuan per session, and improvements are typically noticeable 1-3 months after surgery, although symptoms such as hematoma and scar hyperplasia may occur. Scar hyperplasia after skin grafting may lead to symptoms including scar itching, color changes, thickening of the skin, hardening of texture, and functional limitations. A detailed analysis is as follows:

1. Scar Itching

In the early stages of scar hyperplasia, the newly formed scar tissue is more sensitive to environmental stimuli, and the sensitivity of nerve endings increases, which may cause patients to experience mild itching.

2. Color Change

With the proliferation and congestion of blood vessels within the scar tissue, the scar's color may gradually change from initial red or pink to darker red or purple.

3. Skin Thickening

During scar hyperplasia, excessive proliferation of fibroblasts and over-deposition of collagen fibers within the scar tissue can lead to localized thickening of the skin, forming a noticeable elevation.

4. Texture Hardening

Due to the disordered and overly dense arrangement of collagen fibers within the scar tissue, the texture of the scar tissue gradually hardens over time, with a tactile sensation distinctly different from that of normal skin.

5. Functional Limitation

The proliferation and contraction of scar tissue can exert pulling and compressive forces on surrounding tissues. If the scar hyperplasia occurs near a joint or mobile area, it may lead to joint movement disorders or functional limitations.

It is recommended that patients attend regular follow-up appointments at the hospital after skin grafting surgery, so that doctors can promptly detect and manage signs of scar hyperplasia. Additionally, excessive friction or pressure on the grafted area should be avoided as much as possible to prevent stimulating scar tissue proliferation.
