How is scar constitution

summary

My sister was scalded again. The scar on her body was too obvious after scalding. Later, her family took her to have a skin transplant. Now she is recuperating at home after the operation. My sister always feels that the place of the transplant itches and keeps scratching. After a lot of treatment, let's talk about how to be regarded as scar constitution.

How is scar constitution

Symptom 1: hypertrophic scar is easy to occur in the depth of injury and dermal trauma only. The pathological difference between hypertrophic scar and normal scar lies in the thickening and irregular arrangement of collagen fibers in the deep part of scar. The synthesis and metabolism of collagen were supernormal and continuous, exceeding the speed of catabolism, forming a large number of collagen fibers for a long time.

Symptom 2: the scar surface is obviously lower than the surrounding normal skin. It is usually caused by wound healing of skin, subcutaneous tissue or deep tissue defect. It can also be caused by extensive tissue defect caused by severe suppurative infection of skin and soft tissue.

Symptom 3: the appearance is more flat, with the normal skin level or slightly lower. The surface of atrophic scar is smooth and bright. Hypopigmentation is white, and a few pigmentation areas are dark brown. Generally, it does not cause dysfunction.

matters needing attention

This disease needs to pay attention to: the use of long-acting steroid preparations, directly injected into the scar, to inhibit the excessive collagen in the scar, to achieve the effect of scar degeneration. The main side effects were skin atrophy, discoloration, telangiectasia, necrosis, ulcer and Cushing like syndrome, most of which were reversible. Other chemical drugs, such as cytotoxin and immunosuppressant, have been reported, but serious systemic side effects limit their application.
