What is a Hypertrophic Scar?

Any swelling left behind in place after surgery or trauma is healed is called a hypertrophic scar. Improper treatment is one of the common causes of hypertrophic scars. Improper treatment includes: 1. applying unknown drugs to the wound, 2. excessive debridement

Improper treatment is one of the common causes of hypertrophic scars. Improper treatment includes: 1. Applying unknown drugs to the wound, 2. Excessive debridement. Applying unknown drugs to the wound may cause wound infection or contact dermatitis and prolong healing time. The dermis does not regenerate. Hypertrophic scars are related to the thickness of the remaining dermis. The thinner the remaining dermis, the more likely it is to produce hypertrophic scars. Due to the thickness of the scalpel, when performing debridement surgery, not only the necrotic tissue will be removed, but also part of the dermis will be sacrificed. Therefore, improper debridement surgery can lead to hypertrophy of scars, especially after a debridement surgery, without sutures or skin grafts being given immediately.

Hypertrophic scars often develop bacterial pustules or repeated peelings that lead to new wounds. We do not have to use antibiotic ointments to sterilize wounds, because experiments have shown that most of the sterilization ointments applied to wounds will delay epidermal cell proliferation, directly affect wound healing, and indirectly cause hypertrophic scars.

Hypertrophic scars are prominent scars formed by over-repaired fibrous tissue after epidermal injury. When the protruding fibrous tissue is confined to the original injured site, it is called a hypertrophic scar. If it goes beyond the original injured site and forms a foot-like protrusion like a crab foot, it is called a crab foot swelling. Hypertrophic scars and crab foot swellings are usually red or dull red.

These two scars rarely occur in the elderly and infants, and most often occur from adolescence to about 30 years old, with the same incidence in men and women. According to foreign studies, people with blood type A are more likely to develop such scars; in race, black people also have a higher incidence.

The true cause of the disease is unknown and can only be interpreted as a special constitution. People with this constitution, if they have burns, burns, cuts, lacerations, abrasions, skin infections, folliculitis or acne after surgery, wounds after healing May become hypertrophic scar or crab foot swelling. In particular, injuries are in areas with high skin tension, such as the chest, shoulders and arms, neck, earlobe, chin, jaws, upper back, etc. These areas are also the most common sites for crab foot swelling. Especially when the injury is serious, or when there is no proper and real-time medical treatment, it is particularly prone to the formation of hypertrophic scars and crab foot swellings.

Generally speaking, hypertrophic scars may fade (flatten) naturally within six months, but crab foot swelling usually does not fade naturally and may gradually increase over time.

Hypertrophic scars and

Hypertrophic scar thickening stage, mature stage fibroblasts and vascular endothelial cell apoptosis positive cell index were 6.60 ± 4.43 and 8.90 ± 6.11, respectively, and mature stage were 25.60 ± 5.70 Compared with 26.60 ± 6.02, there were very significant differences in apoptotic positive cell indexes between the two phases of the same kind of cells (P <0.01). The ICE positive expression rate in the thickening stage was significantly lower than that in the mature stage (P <0.01), but the Bcl-2 positive rate was significantly higher than in the mature stage group (P <0.01). Conclusion The decrease of apoptosis may be related to the formation of hypertrophic scars. ICE and Bcl-2 may be involved in the regulation of apoptosis of hypertrophic scar fibroblasts and vascular endothelial cells.
