First, personal factors.
This is the primary factor to determine whether the scar is obvious or not. Although it can't be detected at present, compared with normal people, it is confirmed that some people have obvious scar hyperplasia and slow regression after operation, which is what the people call "scar constitution". This trauma patient can't control it. But for those who are preparing for plastic surgery, they still need to pay attention and take a cautious attitude.
In addition, age, skin color and metabolism also have effects on scars. When the fetus is in the uterus, surgery will not leave scars, while young people are more likely to leave scars than the elderly; The darker the skin color, the more obvious the scar will be; When metabolism is vigorous, such as pregnancy, scar hyperplasia and even keloid attack are more likely than other times.
Second, the doctor's operation technology
The doctor's operation is a necessary factor to determine whether the scar is obvious or not. Thorough debridement, hemostasis, excision of some abraded skin, anatomical reduction, tension-reducing suture, local incision plastic surgery, fine needle suture and postoperative anti-scar treatment are all effective measures to reduce scars, which are the smallest scars left in all operations and are favored by more and more beauty lovers, especially women, who often seek the help of plastic surgeons after injury.
Three. The site of injury or surgery
In some special parts, especially chest, shoulders, back, joints, earlobes and perineum, even minor injuries may lead to obvious scar hyperplasia, which may be related to local skin tension and many pigment cells.
Fourth, the specific situation of the wound.
First, the direction of the wound. The wound tension parallel to the skin tension is the smallest, so the postoperative scar hyperplasia is also the most obvious, especially in the elbow joint and other parts. If the long axis of the wound is perpendicular to the limb, the postoperative scar will inevitably proliferate obviously.
