The donor site of a split thickness skin graft undergoes scar formation.
Donor sites may exhibit hypopigmentation, hyperpigmentation, redness,
and disruption of skin texture. Parts of harvested skin, and chip skin
were grafted back onto the donor site to improve the skin appearance, a
process we named “recruited chip skin grafting.” Thirteen patients who
needed split thickness skin grafts were treated with recruited chip skin
grafting. Five patients were used as controls, for whom the donor sites
were treated by the traditional method. Part of the split thickness skin
was minced with two surgical blades (number 24) to an approximate
particle size of less than 0.5 mm. Chip skin was spread and transplanted
onto the donor site and covered with polyurethane foam. Six months after
the operation, the donor sites were scored for hypopigmentation,
hyperpigmentation, redness, and disruption of skin texture. The gross
appearance was evaluated from the total score. Donor sites treated with
recruited chip skin grafts had significantly improved appearances
compared with those of the controls. Donor sites with a treated area of
more than 5% of the total area tended to have better results. In
conclusion, recruited chip skin grafting is a good method for improving
the appearance of the donor site. |
