PLASTIC SURGERY OF WOUND DEFECTS WITH FREE GRAFTS AFTER MALIGNANT SKIN TUMORS EXCISION: A PILOT STUDY

Abstract

Aim. To evaluate the effectiveness of applying negative pressure bandages (VAC bandage) in patients with malignant skin tumors after closing defects with free skin grafts and to compare it with fixation of skin grafts by the ordinary ointment bandages. Materials and Methods. 61 patients with malignant skin tumors who underwent surgical treatment at the National Cancer Institute from 2019 to 2023 were included in the study. For the wound defects closure, the split skin grafts were applied in all patients. At the time of surgery, after closing a wound defect by a split skin graft, a negative pressure dressing (VAC bandage) was applied in 41 patients for 7 days (group 1). In 20 patients, a transplanted skin graft was fixed after surgery by an ordinary ointment pressure bandage (group 2). The immediate results were evaluated one week after surgery. Results. Complete engraftment of the flap in group 1 was observed in 53.7 ± 7.8% cases, in group 2 this result was achieved in 5.0 ± 4.8% patients (p = 0.002). The complete graft necrosis occurred in 1 case in group 1 vs. 2 cases in group 2 (p = 0.496). Conclusion. The results of the engraftment in postoperative wounds were significantly better in the VAC-bandage group in terms of the number of the complete engraftments compared to the conventional pressure ointment bandage group.
