Negative Pressure Wound Therapy for Split Thickness Skin Grafting to the Lower Leg After Excision of Skin Tumour: A Multicentre Randomised Study

Negative pressure wound therapy (NPWT) applied over the split-thickness skin graft on the lower leg after tumour excision. A protective silicone interface layer will be used, with continuous negative pressure of -125 mmHg applied until postoperative day 5, unless earlier change is clinically indicated.

Traditional dressing applied over the split-thickness skin graft on the lower leg after tumour excision. The dressing consists of one or more layers of foam dressing applied on top, which may or may not be fixed with sutures according to surgeon preference, and an elastic bandage applied over the foam to provide gentle, even compression and immobilisation of the graft. The dressing will remain undisturbed until postoperative day 5 unless earlier change is clinically indicated.
