Advancement Skin Grafting: A Retrospective Comparative Study of Donor-Site Morbidity Following Split-Thickness Skin Grafting
This retrospective comparative study demonstrates that a novel advancement skin grafting technique significantly reduces donor-site healing time and improves scar quality and quality of life compared to conventional split-thickness skin grafting, offering a viable option for patients with abdominal skin laxity.

When a large area of skin is lost to injury, infection, or surgery, doctors often turn to a time-tested solution: taking a thin layer of healthy skin from one part of the body and moving it to cover the wound. This procedure, known as a split-thickness skin graft, is a workhorse of reconstructive surgery. However, the act of harvesting this skin leaves behind a raw, open wound at the donor site, usually on the thigh or abdomen. While this wound eventually heals on its own, the process is often slow and uncomfortable. As the skin regrows, it can leave behind raised, red, or itchy scars that linger for months, affecting a patient's daily life and confidence. For decades, surgeons have sought ways to speed up this healing process and improve the final look of the scar, but the standard method of letting the wound heal by itself has remained the norm.
A team of researchers at the Plastic Surgery Hospital in Beijing and the Guangdong Provincial People's Hospital recently revisited this problem with a fresh approach. They tested a technique they call advancement skin grafting, which changes how the donor site is managed immediately after the skin is harvested. Instead of leaving the entire donor area open to heal on its own, the surgeons divide the area into two sections. They take the skin graft from one section, but they keep the adjacent section of skin intact. They then gently stretch this remaining strip of skin over the open wound and stitch it into place, effectively closing the gap with the patient's own living tissue. The study compared this method against the traditional approach in a group of patients who underwent surgery between 2010 and 2023.
The results showed a clear difference in how quickly patients recovered. In the group that received the new advancement technique, the donor wounds healed completely in an average of about 21.5 days. In contrast, patients who underwent the conventional method, where the wound was left open, took an average of roughly 33.4 days to heal. This reduction of nearly 12 days meant that patients spent less time with open wounds, less time in the hospital, and less time dealing with the discomfort of daily dressing changes. Beyond the speed of healing, the quality of the scars was also superior in the advancement group. When evaluated six months after surgery, the scars from the new technique were flatter, softer, and less red than those from the traditional method. Patients in the advancement group also reported a significantly better quality of life, with fewer worries about their appearance or itching.
The researchers found that this method worked best for patients with loose skin on their abdomen, such as those who have had children or carry extra weight, as this laxity allows the skin to be stretched forward without excessive tension. While the technique did not completely eliminate the risk of discoloration in the scar, it did significantly reduce the other common problems associated with skin grafting. The study suggests that by simply closing the donor wound with a flap of nearby skin rather than leaving it to heal from the bottom up, surgeons can offer patients a faster recovery and a more pleasing cosmetic result. This approach does not replace all other methods, but it provides a valuable option for specific cases where minimizing the trauma of the donor site is a priority.
