If the lip band surgery is not sutured properly, depending on the degree of healing of the wound, the surgical suture can be re-performed, or no special treatment is needed, and the wound can be temporarily observed. 1. Surgical suture: If there are symptoms of suture detachment or cracking of the lip ligament surgery, it will affect the healing of the wound and be accompanied by obvious bleeding and other symptoms; in this case, it is recommended to consult a doctor in time to reopen the alignment of the wound in order to promote the normal healing of the wound effectively. 2. Observation: If the postoperative wound is not properly sutured, but the bleeding of the wound is small and does not affect the normal healing of the wound, no special treatment is needed, and the wound should be temporarily observed and allowed to heal on its own.
