According to experts from the Scar Center of Nanjing Hengli Plastic Surgery Hospital, whether there will be scars after suture removal has a certain relationship with personal physique, the degree of contusion at the wound, whether the skin edge is complete and whether the wound is infected. If the patient is young, even if there is a scar, it will not affect the appearance and does not need treatment. Children's organizations have strong self-repair ability. As long as there is no scar, after three years of repair, the scar should not be obvious If the scar is still obvious, plastic surgery should be done at the right time. General scar tissue resection and suture can minimize scars. How to prevent suture scar? If you want the patient to leave no scar after suture removal, you need to pay attention to the following points: 1. Take out stitches early, preferably within five days, so as not to leave obvious needle holes. 2. Continue to bandage the wound for several days after taking out stitches. Don't scratch the wound and let the scab fall off naturally. 3, you can use the tension-reducing tape, which can prevent the scar tissue from proliferating. 4. Protect yourself from the sun for the next few months and eat less things containing pigments. 5. After the stitches are removed or the wound is initially healed, massage therapy and compression therapy can be performed as appropriate. In case of scar left by suture, it needs to be treated in time, and the scar repair scheme should be decided mainly according to the area and degree of suture. In view of the situation of scar protrusion after needle sewing, comprehensive treatment can be carried out by introducing scar-removing drugs, polishing, physical pressure therapy and external drug repair. Surgical suture scar resection should be based on the specific situation of patients, and the optimal comprehensive treatment should be carried out.
