Conventional treatment methods for nevus of Ota include: cryotherapy, laser treatment, surgery (dermabrasion or skin grafting), etc.

Cryotherapy: Frostbite tissue from the surface of the skin layer by layer from the surface to the inside. Because the lesion is deep, cryotherapy can leave scars.

Surgical treatment: The skin of the lesion area is rubbed off (just like terrazzo), or the skin of the lesion area is removed, and finally skin grafting.

Laser treatment: burn off the skin layer by layer from the surface to the inside. This method has the advantage of minimizing postoperative scars and is a popular treatment method nowadays. Specifically, I suggest that the poster, Dr. Changsha Fian, undergo a plastic surgery examination at No. 417, Section 3, Furong Middle Road (6th Floor, Building 6, Second People's Hospital of Hunan Province).
