When the wound bleeds, it means that the depth of the damage has reached the dermis, which stimulates fibroblasts to produce collagen to repair the wound. However, in some people with better physique, when the skin tension is high, the fibroblasts responsible for the repair work will overreact, causing the wound to heal instead of flushing scars, but prominent 疤痕增生 scars or keloid swelling. However, hypertrophic scars and keloid swelling are very similar in appearance. Many patients think that their scars are keloid swelling, but they are actually hypertrophic scars.
Hypertrophic scar? keloid swelling? A fool can't tell
What conditions are prone to form hypertrophic scars or keloid swelling?
people of color such as Asians and blacks are more common.
past medical history or family history of hypertrophic scars or keloid swelling.
It is usually the area with high mobility or greater skin tension, such as earlobe, lower jaw, neck, shoulders, upper back, chest, abdomen (lower abdomen), limbs and joints.
How to treat hyperplastic scars or keloids?
1. Steroid injection in local lesions: treatment approximately once every 4 weeks.
2. Liquid nitrogen cryotherapy: using low temperature to cause ischemic necrosis of scar tissue, the same treatment is about once every 4 weeks.
3. Local injection of chemotherapeutic drugs into the lesion: Use cytotoxic drugs to induce apoptosis of scar tissue.
4. Surgical resection combined with postoperative radiotherapy: Surgical resection can quickly improve scars and reduce scar volume, but postoperative radioactive electron beam therapy should be combined to destroy fibroblasts in tumor tissues and prevent scar tissue from reproliferating.
5. Laser treatment: Vascular lasers, such as yellow lasers or dye lasers, more specifically use hemoglobin to absorb laser energy, thereby blocking blood flow to scar tissue and causing it to shrink. Combined steroid injections are usually used to improve treatment results.
6. Local botulinum injection: This is a new treatment method. The possible treatment mechanisms include reducing the tension of scar tissue and inhibiting the activity of fibroblasts.
