Q) This procedure replaces the achromic epidermis with a cultivated epidermis endowed with melanocytes. What is the advantage of this procedure?
A) Timedsurgical de-epithelialisation maintains the integrity of the dermis. If the dermis is integral, the graft will take root perfectly. After this procedure, the re-pigmented skin will look exactly like the patient's normal skin, without any surgical or cicatricial artefacts.
Q) Can this technique be used in all cases of vitiligo?
A) No, only in stable vitiligo and piebaldism.
Q) Can scars be re-pigmented, too ?
A) Yes. We have performed this procedure successfully on numerous large achromic scars.
Q) Can this technique be used on small achromic scars?
A) No, it is too costly. If the scars are small, we only use a Timed micro-vaporisation of one three-hundredth or two three-hundredths of a second at a power of 50 Watts. Once the achromic epidermis over the scar and at the edges has been removed, the scar will be re-epithelialised from the surrounding epidermis of the healthy skin, and the area will take on a normal pigmentation.
Q) Which achromic lesions can be treated by means of timedsurgical micro-vaporisation?
A) We treat small iatrogenic achromic lesions and those caused by the sun. We also use timedsurgical micro-vaporisation to treat achromic surgical scars on the face or body, such as those due to elastic face-lifting or those of the areola.
Q) For which other procedures can pulsed timedsurgical de-epithelialisation be used?
A) It can be used to eliminate deep wrinkles of the lip and “crow’s feet”, to de-pigment dermal-epidermal patches, and to treat recurrent plane warts and epidermolysis bullosa. In this last procedure, the pathological epidermis is replaced with an epidermis modified by means of genetic engineering.
