Abstract

Closure of large wounds may require full-thickness skin grafts, but their use is burdened by donor tissue availability and morbidity; the use of the purse string technique is an elegant way to overcome this problem. The study highlights the gain in terms of graft donor site morbidity and oncological radicality. The study included a group of 47 patients who underwent surgical excision for skin cancer and whose wounds were covered using a purse string suture and a skin graft. Radius of the defect left was measured after the lesion's excision and after the purse string suture. Thereafter, the difference between the initial defect area and the area after purse string suture was calculated. Initial defects ranged from 3.85 to 61.5 cm2 . After skin graft, the purse string suture ranged between 2.2 and 40 cm2 (mean area = 14 cm2 ). Gained area before the graft measured from 1.3 to 21.5 cm2 (mean gained area = 7.1 cm2 ). Average reduction was 33%. The technique allows a reduction of the size of the area to be grafted and the skin graft donor area, thus increasing the possibility of the feasibility of full-thickness grafts. In addition, it allows an optimal observation both of the area of tumour excision and margins during follow-up controls.
