Many people often ask why my knife is very thin and flat when it has been sutured. Later, it slowly bulges and widens it. The author consulted many plastic surgeons and summarized the following reasons:
1. Congenital constitutional factors
Our body is very different. If we reflect from the post-injury, some people are not easy to leave scars visible to the naked eye. Some people are prone to scars and even serious scar hyperplasia. Scar physique); if we set the first person who is not easy to leave scars visible to the naked eye as 0 points, and the second type of scar physique is specified as 100 points, then most of us are injured after the body reflects the score Should be in accordance with the normal distribution law distributed between 0-100, some people tend to 0 points this end, and some people tend to 100 points this end, the score is correspondingly low, the treatment has a good effect is easier; score corresponding High, the effect of healing after scar healing is worse, or it is more difficult to achieve better results in surgical treatment. If it is the latter, we need to arrange other treatments (such as anti-caries products, medical elastic sleeves, etc.) Etc.) to increase the possibility of achieving good results.
2, the skin tension on both sides of the suture
Through research, it is found that the greater the skin tension on both sides of the suture, the less likely the wound is to be tight, and the body will receive a signal of "required hyperplasia", and more scar tissue cells will grow to heal the wound. After a long time, it is easy to form the common "sputum" of the naked eye; on the contrary, if the skin tension on both sides of the suture is smaller or there is no tension, the skin is tightly closed, and the signal of "required hyperplasia" accepted by the body is not strong, only need Tissues with less hyperplasia can heal the wound, so that the scar after healing is generally linear scar.
The experience and focus of ordinary surgeons on wounds is generally to stop bleeding and prevent infections, especially in emergency situations such as car accidents. Rescuing life is of paramount importance. Prevention or reduction of scar formation during surgery is rarely considered or considered. The problem. Even doctors in the field of plastic surgery have different treatment experiences for scars, birthmarks and sputum in different parts. There are also obvious differences in the way of suturing. Doctors often joked that "the suture style can be seen from the suture style. "Level" actually has some truth. For example, the same three-centimeter wound. If you are on the arm, you may want to consider reducing the tension to the greatest extent and promote healing. But on the cheek, we must consider The problem of tension should also consider the influence of cheek lines on organs such as nose and mouth.
Therefore, in the treatment of scars, reducing the tension on both sides of the scar is the core problem in the treatment of scars. For the time being, this is the purpose of reducing the tension of suture wounds through specific suturing techniques, and it is also the key to achieving good surgical results in "super-surgical suture fine surgery".
3, the level of patient cooperation
Treatment requires patient coordination and requires the patient to act voluntarily. After the treatment of scars, birthmarks, and sputum, the knife edge usually has a proliferative period of three to six months. This is also the best period for the scar drug to work. Therefore, we recommend that patients should use drugs that inhibit hyperplasia of scars; Do not eat spicy food (chili, soy sauce, seafood, etc.). These are all spontaneously done without the supervision of a doctor. Whether it is to inhibit scar hyperplasia drugs or spicy food on the knife edge scars are slowly added, there is no obvious change in a short period of time, but after half a year, scar hyperplasia will significantly affect the treatment effect.
Throughout the three factors affecting the treatment effect of scar, the first factor is the innate factor, which is the basic factor for the treatment of scar, we can not change; if you can judge the constitution before treatment, you will choose effective adjuvant treatment. . The second factor and the third factor are that we can choose the best treatment plan and adhere to the postoperative medication through artificial control factors, so as to increase the possible therapeutic effect.
