All types of surgical treatment for vitiligo aim to transfer melanocytes (pigment producing cells) from normal skin (donor site) to the skin affected by vitiligo.
One of the surgeries is Punch Grafting and the most common surgical technique used. Bit of skin from the donor site of about 2mm are punched out. The donor site is mostly thigh or buttocks. The punched out skin is then placed on vitiligo affected skin.
Surgery is only performed on patients with stable diseases i.e. it hasn’t progressed over a period of 6-12 months.
