Introduction: Wound healing requires a complex physiological process to restore skin integrity following injury. Despite advancements in wound care, effective surgical management of complex wounds remains challenging. This study explores the combined use of pure hypochlorous acid (pHA) solution* and ovine forestomach matrix (OFM) grafting** in plastic surgery wound reconstruction as synergistic therapeutic approaches. pHA helps prepare complex wounds for reconstruction through germ removal and enhancement of mechanical debridement properties, promoting healing with low cytotoxicity. OFM grafting provides a biologically derived scaffold that supports cell migration, proliferation, and enhanced tissue vascularization.^1,2 This case series explores the proposed synergy between pHA's unique germ and necrotic tissue removal effects and OFM's structural benefits, with a goal of improved surgical wound healing outcomes.

Methods:

At one academic hospital from June 2023 to June 2024, data was collected by retrospective review of all patients who underwent OFM grafting in conjunction with pHA wound bed irrigation by a single plastic surgeon. Perioperative techniques and protocols were examined. In addition, patients’ demographics, comorbidities, and operative cultures were reviewed. Outcomes were assessed in the outpatient wound center based on post-operative complications and healing outcomes.

Results:

24 patients with varying acute and chronic wounds requiring plastic surgical reconstruction were included in the analysis. All patients received intraoperative pHA irrigation and OFM grafting. Patients had wound preparation preoperatively with pHA and/or inpatient post-surgical graft and donor site management with pHA. 15 patients healed without reoperation. 3 had prolonged healing courses. 1 patient experienced minor wound dehiscence which resolved with local wound care. 3 patients required reoperation. 5 patients were lost to follow-up but upon discharge had no known wound complications. Cultures were sent from all patients revealing growth of various pathogens.

Discussion:

This study demonstrates the potential benefit of combining pHA solution with OFM grafting for improving healing outcomes in patients with complex wounds. The results reveal high rates of successful healing. A majority of patients achieved wound closure without reoperation. While some patients experienced minor complications, overall outcomes suggest the synergy of pHA and OFM may enhance healing by promoting antimicrobial effects and providing a supportive scaffold for tissue regeneration.
