05. Re-pigmentation of stable vitiligo of the face by means of timedsurgical de-epithelialisation and autologous grafts of cultivated epidermis
Areas of stable vitiligo and piebaldism can easily be repigmented by means of timedsurgical de-epithelialisation followed by the grafting of autologous keratinocytes and melanocytes cultivated from a 1 cm² fragment of skin taken from a normopigmented area about 20 days earlier. Once local anaesthesia with mepivacaine has been carried out, de-epithelialisation is started. De-epithelialisation is carried out at 1 or 2 Watts by means of the pulsed current specifically designed for de-epithelialisation of the skin. The edge of the corner of an EM 10 Yellow electromaniple® is used for de-epithelialisation. Pulsed timedsurgical de-epithelialisation enables the achromic epidermis to be detached from the dermis, while maintaining the integrity of the papillae and the papillary-capillary plexus.
