Wound healing outcomes following treatment with synthetic hybrid-scale fiber matrix after resection of soft tissue tumors or infections.

BACKGROUND

Wide excision of soft tissue tumors or infections often results in large defects that can be challenging to manage. Advanced treatment modalities-including NPWT, skin grafts, and xenografts-can all be considered for post-resection wound management, but each has its limitations. An SHSFM, engineered to resemble human extracellular matrix, has demonstrated positive wound healing outcomes in prior studies.

MATERIALS AND

METHODS

Adult patients at a single institution who underwent resection of soft tissue tumor or infected tissue followed by treatment with SHSFM from 2020-2023 were retrospectively reviewed.

RESULTS

Ten patients were included in the review after meeting the inclusion criteria. Overall, 7 of 10 wounds had documented complete closure, with 3 lost to follow-up. Average time to wound closure was 119 days. Patients either healed via secondary intention or were bridged to a split-thickness skin graft. The average VSS score was 3.3 when assessed.

CONCLUSION

The current case series demonstrated that the SHSFM can support granulation tissue formation over exposed structures as a bridge to skin graft or can completely reepithelialize large wounds without skin grafting. The SHSFM offers a novel treatment option for post-resection surgical wounds.
