Application of dermal regenerative template in reconstructing skin defects after plantar malignant melanoma excision.

Purpose: The excision of plantar malignant melanoma frequently leads to wide skin defects on the plantar surface. This study aimed to investigate the advantages and feasibility of dermal regenerative template reconstructing plantar blemishes caused by malignant melanoma.

Methods: 28 patients identified with plantar malignant melanoma were included in this retrospective article. Eighteen patients received immediate skin grafts after wide excision skin graft (SG) group), whereas the remaining 10 patients were treated with dermal regenerative template (DRT) (Lando ®, Shenzhen TsingCare Medical Co. Ltd) 14 days before skin grafts (DRT group) and the postoperative survival rate in the two groups was analyzed. During the 6-month follow-up, we compared the scar index, plantar pain, and recurrent skin graft ulcer incidence on the skin grafts area.

Results: Postoperative survival rate in the DRT group (91.75% ± 7.64%) was higher than in the SG group (80.51% ± 7.17%). The DRT group showed less scar formation on Vancouver scar scale (VSS index): 3.40 ± 1.07 than the SG group (VSS index: 6.33 ± 0.68). The dermal regenerative template alleviated plantar pain and decreased the incidence of ulcer on the skin grafts area.

Conclusions: The dermal regenerative template not only improves the survival rate of skin grafts but also alleviates scar condition, plantar pain and recurrent skin graft ulcer. This study provides a new reconstructive strategy in plantar skin defects after the excision of malignant melanoma.
