Micrografting in the treatment of severely burned patients

The micrografting technique, employed to treat patients with extensive TBSA burns and reduced areas of healthy donor skin, was assessed simultaneously with traditional mesh grafts (STSG) or Tiersch grafts in the treatment five severely burned subjects (average TBSA burned 35.6 per cent; average per cent of full thickness wounds 32.6 per cent). At the first clinical control on day 6 post-surgery 93 per cent of the micrografted area was in situ and healthy: epithelialization of the wound sites was complete at day 21. Meshed STSG yielded 90 per cent attachment at day 6 post-surgery, with epithelialization complete at 12 ± 2 days post-surgery. Functional results were equivalent no matter what technique was used, while aesthetic results were better in the areas where micrografting was carried out. Although the micrograft technique is labour-intensive, if the expansion needed is at least 1:6, the aesthetic and functional results obtained are comparable to, or better than, those with meshed grafts. Also, large segments of micrograft are not compromised if a small area of mesh becomes detached, and epithelialization is faster and more uniform, enabling a reduction in both infection and length of hospital stay
