A scar is a mark that represents a wound to the skin. This kind of trauma may be caused by trauma or it may be necessary for surgery. However, due to the different degree of trauma, whether the healing process is smooth or not, the position of the wound on the human body is different, and the size is also obviously different. Especially with the progress of modern society, the love of beauty not only represents a right, but also embodies a kind of self-esteem. Scar is one of the most common problems in cosmetic surgery clinic. In addition to the appearance, in fact, many scars can cause uncomfortable itching, pain and chapping. If the scar contracture is unfortunate, it will not affect the normal function of limbs or five senses. These scars must be treated actively.
● Treatment of scar: It can be divided into three categories:
The first category: ※:
1. Compression therapy: put the beauty tape close to the scar and massage hard on it to make the scar smooth gradually. This method must last for more than 6 months to be effective.
2. Silicone patch sticking method: stick a silicone patch on the scar for eight hours on the first day, and it can be increased to 12 hour after the skin gradually adapts, and the effect is good for six months. As for the mechanism of action of silica gel tablets, Quinn thinks that it is the chemical action of continuous release of silica gel, and Swada and Son think that it is the physiological action of hydration and occlusion that causes scar inhibition. PS。 The above item 1.2 is applicable to those with scars less than half a year.
3. Inject steroids into the scar: Inject long-acting steroids directly into the scar to inhibit excessive collagen in the scar, thus achieving the effect of inhibiting the scar.
Ketchum suggested dose:
Maximum dose/frequency of administration
Adult 120mg, injected/kloc-0 once a month for 4 ~ 6 months.
1-5 years old children 40mg
6- 10 years old 80mg.
4. Radiation: In the past, radiation was used to kill, inhibit or transform into fibroblasts to control the excessive proliferation of scar tissue. At present, this method paper is reserved for large-scale crab foot swelling patients who are ineffective in steroid treatment.
5. Others: The methods mentioned in the literature that can inhibit scars are:
O vitamin a
O vitamin e
Inhibit collagen, such as BAPN(β- aminopropionitrile), penicillamine and colchicine.
O inhibition of asiaticoside in muscle fiber cells during swelling of crab feet
Zinc oxide (zinc oxide)
O antineoplastic agents: such as methotrexate (MTX)
O immunotherapy: such as interferon and TGF-B inhibitor.
The second type: laser. ※
According to the principle of laser scar removal, it can be divided into two types:
O A-type dermabrasion laser can be divided into CO2 laser and Er-YAG laser, which can smooth scar bulge, and superficial sunken scar can also use this principle.
O Depigmented laser: It can be divided into dye laser and pulsed intense light (photoderm). The laser acts on the blood vessels and heme in the scar, which makes the color of the scar fade and shrink gradually. This kind of laser is especially suitable for people who have been scarred for less than half a year and have dark colors.
The third type: operation. ※
When the scar has been stable (usually the scar has been formed for more than half a year) and the appearance is wide, thick or indecent, surgery should be used to control the scar. Surgical methods include scar excision, re-sewing, Z-shaped or W-shaped scar repair, dermabrasion and so on. If the scar is too big, you can consider removing it by stages or placing a tissue expander for a period of time before removing the scar.
Drug treatment of scar: compound heparin sodium allantoin gel has the effects of anti-fibroblast proliferation, anti-inflammation and softening scar tissue; Silicone spray, silicone ointment and silicone patch are all scientific choices to soothe scars at present.
