Congenital pigmented nevus (also called animal skin nevus) is mainly removed by excision, skin grafting and flap transfer internationally, and there are differences between the skin grafting site and normal skin color. Flap transfer requires prior preparation such as skin expansion, postoperative scars, and inevitable intraoperative nerve damage in some patients. Congenital pigmented nevi on the eyelids and eyebrows are difficult to perform the above treatment and become a difficult point of treatment. Radiofrequency ablation is a minimally invasive procedure that effectively avoids the above disadvantages. Facial lesions, especially those located at the lid margin and brow, are effectively removed under the microscope, and are characterized by: light damage, no deformation, no nerve damage, and no scarring.
