Background
Pigmented nevi are the more common benign lesions on the skin, with about 40% occurring in the facial area. No treatment is generally required, but frequent irritation should be avoided. The facial mole removal is suitable for removing pigmented nevus at the parts which are easy to be stimulated, lips, nose and the like by considering the surgical removal. When symptoms and signs such as rapid increase of pigmented nevus, deepening of pigment, itching, ulceration, bleeding and black pigment spots on the skin around the nevus occur, malignant change is considered to be possible, and timely surgical excision is required. Once malignant change occurs, extensive excision is required in time. Local infiltration anesthesia is generally adopted during surgical excision. The children can select basal anesthesia and local anesthesia. The operation position can be a supine position or a sitting position. The incision design is dependent on the size of the lesion. For patients with small pathological changes, when the excision area is less than or equal to 1mm, the patients can be directly excised without suturing; if the lesion is larger, when the excision area is larger than 1mm, a fusiform incision design is made according to the dermatoglyph direction, and the excision incision needs to be sutured after the lesion is to be excised. In addition, the notch is preferably tapered from the outside to the inside and has a slope shape.
The existing mole excision is to use a mole excision scalpel to exfoliate or excise moles, mainly depends on the skill and experience of a surgeon, but easily causes uneven incision or enlarges the incision area, and is not easy to suture; and the operation time is long, the efficiency is low, and the like.
