Normally, the color of hair and skin is determined by melanin. Vitiligo occurs when cells that produce melanin die or stop functioning. Vitiligo affects people of all skin types, but it may be more noticeable in people with darker skin.
Commonly used treatment for vitiligo:
Miniature Punch Grafting: It is one of the most commonly used techniques, due to its simplicity and efficacy. Bits of skin about 2 mm in diameter are punched out from the donor site on buttock or thigh and placed on the donor site of vitiliginous skin, where recipient chambers have also been created by punches.
Suction Blister Grafting: In this procedure, negative pressure is applied to the normally pigmented donor site to promote the formation of multiple blisters.
Split Thickness Skin Grafting: This procedure involves shaving off thin layers of skin from the donor site. In comparison to punch grafting and suction blister grafting, split thickness skin grafting can cover larger areas and produces uniform pigmentation with no cobblestoning.
Autologous Non-Cultured Epidermal Cell Suspensions: This procedure allows large areas to be treated in one session using a small donor graft. They result in excellent colour matching.
Cultured melanocyte suspensions; This procedure allows a large area to be treated in a single session. It uses a larger donor-to-recipient ratio than the non-cultured technique.
