title: Comparison of minipunch grafting versus split-skin grafting in chronic stable vitiligo.
abstract: BACKGROUND
  Minipunch grafting (MPG) and split-skin grafting (SSG) are common outpatient procedures for the surgical treatment of chronic stable vitiligo. However, there is a paucity of literature comparing the two procedures by the same group of investigators.
  
  
  OBJECTIVE
  To compare the two techniques in patients with chronic stable localized vitiligo.
  
  
  METHODS
  Sixty-four patients with stable vitiligo of 6 months duration were randomized into two groups to be taken up for MPG or SSG in a representative patch followed by PUVAsol therapy for 3 months. They were evaluated 3 months postoperatively for the degree of repigmentation and side effects.
  
  
  RESULTS
  In the MPG group, 644 grafts, 2.5 mm in size, were placed on a total vitiliginous area of 521.25 cm2, whereas in the SSG group, 153 grafts covered a 1,489 cm2 recipient area. Three months postoperatively, in the first group, 15 cases (44.1%) showed very good to excellent (> 75%) repigmentation compared with 25 cases (83.3%) in group 2. Following MPG, 81 grafts (12.57%) were rejected. Cobblestoning was the main side effect, occurring in 13 cases (38.23%), and a variegated appearance was observed in 7 (20.58%) patients. The complications noted after SSG were achromic fissuring in four (13.3%) cases, graft contracture in four grafts (2.61%) in three patients, and rejection of seven grafts (4.57%) in one case; tire-pattern appearance in two patients (6.6%); milia formation in four (13.3%) patients; and depigmentation of the grafts in two (6.6%) cases. In both groups, superficial scarring was noted at the donor site in all cases, whereas hypertrophic scarring occurred in 3 (10%) patients after SSG.
  
  
  CONCLUSIONS
  SSG carries a distinct advantage over MPG in producing excellent cosmetic matching over larger areas using fewer grafts, especially over the face and extremities.
