Scarring At Donor Sites After Split-Thickness Skin Graft: A Prospective, Longitudinal, Randomized Trial

摘要

OBJECTIVE; The aim of this study was to evaluate scarring at split-thickness skin graft donor sites 8 years after surgery.METHODS; At surgery, 67 patients were randomized to hydrofiber, polyurethane foam, or porcine xenograft treatment. Scars were evaluated with the Patient and Observer Scar Assessment Scale.RESULTS: Results showed significant differences in observed scar outcomes at donor sites, leaving the polyurethane foam-treated and the porcine xenograft -treated patients with the least satisfying scars. Multivariable regression analysis showed that the group treated with the xenografts had worse scores for overall opinion of the scar than did the other groups (P = .03)，the most important factor being pigmentation. There was no correlation between duration of healing time and quality of the scar.CONCLUSIONS: There were significant differences among the groups，with the hydrofiber group being the most satisfied with the appearance of their scar.
