Techniques of Microskin Grafts Distribution on Ablated Vitiliginous Areas

Abstract

Microskin grafts (MSGs) are prepared by mincing the ultra thin or thin split thickness skin graft (STSG-UT, STSG-T) with scissors into tiny pieces smaller than 1 mm in size. These MSGs are then evenly spread on the abraded vitiliginous area with the help of forceps or spatula. The grafting operation must be performed gently and carefully, avoiding excessive movement of the MSGs on the wound. The wound is wrapped with petrolatum gauze, cotton pads and splinted, in order to keep the recipient site immobile near joint. The recipient site is examined 7–11 days postopera-tively. The MSGs that do not vascularize on recipient area due to its non contact on recipient bed become black and falls out as crust. This again emphasizes the usefulness of very thin and even spread of MSGs on recipient site and at the same time minimizes the donor area.
