Many girls who love beauty will make themselves more beautiful through surgery, but some of them find that there are threads coming out after the stitches are removed. Do you need to go to the hospital to remove them again? About the problem of surgical sutures. There are two types of surgical sutures. Absorbable threads and non-absorbable threads. Non-absorbable threads are more resistant and can protect the wound. Therefore, most of the sutures on the skin layer are made with non-absorbable threads. For plastic surgery incision sutures, the internal incisions are made with absorbable threads, which do not need to be removed after surgery, such as internal eye bags, chin augmentation and rhinoplasty, while the external incisions are made with non-absorbable threads, which need to be removed after surgery, such as total eyelid cutting, external eye bags and brow cutting. If the stitches have penetrated deep into the skin, it is usually not mandatory to take them out, they will gradually come out over time, so if there is no inflammation or redness, there is no need to worry. If you find that the stitches are coming out, it is a rejection reaction of the stitches. After surgery, the incision “emergence” of thread is a rejection reaction, mainly related to personal constitution, most people have a very light reaction to sutures, only a small number of people with strong rejection reaction, can appear after a period of time after surgery “emergence of thread” phenomenon. In addition, some people such as smokers, alcoholics, drug users, diabetics, liver and kidney dysfunction, hormone users or drug users are also prone to rejection reactions. The silk thread itself is a foreign substance to the body, and it is difficult to completely remove the protein component, so it is more likely to cause rejection reactions for the above-mentioned sensitive people. What should I do if I have a thread reaction? The thread reaction does not require all the threads to be drained. Generally, the threads that are drained are the ones with large knots and long residual stitches. After the thread reaction, most of the skin will be broken, oozing and other phenomena, so pay attention to maintain local hygiene to prevent infection, if necessary, go to the hospital, for the exposed threads, you can go to the hospital to ask the doctor to remove the threads by changing the medicine.
