Whether a 2cm chin wound should be stitched or not should be analyzed objectively based on whether there is active bleeding in the local area and the patient’s own healing ability, etc. 1. If the depth of the 2cm chin wound is deeper and there is active bleeding in the local area, and if the patient is old and weak and has poor healing ability, the wound may be seriously infected if it is not stitched up. At this time, if the wound is not sutured, it may cause external bacteria and viruses to enter the wound and cause serious infection. It is recommended that the patient should perform wound debridement, suturing and hemostasis treatment in time, which can effectively avoid serious infection of the chin wound and most of the patients can get better treatment results.2. If the degree of the patient’s chin injury is very shallow, there is no active bleeding on the surface and the patient’s own healing ability is strong, then the patient can be thoroughly debrided by vital iodine, hydrogen peroxide, saline, and disinfected, and the local topical application of Yunnan Baiyao powder and sterile gauze bandage can be applied, After 3-5 days, most patients’ wounds can be scabbed and healed without stitches.
