Abstract
Background: Split-thickness skin grafts (STSGs) remain a valuable tool in the reconstructive surgeons' armamentarium. Staple or suture mechanical fixation (MF) serves as the gold standard of care, though fibrin glue (FG) has gained popularity as a fixation modality. We compare STSG outcomes following application of FG versus MF through a study of lower extremity wounds. Methods: A retrospective review (2016-2019) of patients who underwent a STSG was performed. Two cohorts consisting of patients undergoing a STSG with FG or MF (suture or staple) were matched according to wound size, wound location, and body mass index. Results: A total of 67 patients with 79 wounds were included (FG: n=30, wounds=39; MF: n=37; wounds=40). There was no significant difference between groups regarding time to 100% graft take (FG: 39 days, MF: 35.1 days; P<.384) or 180-day graft complications (FG: 10.3%, MF: 15%; P<.737). Adjusted operative time for FG (51.8min) was lower than for MF cases (67.5min) at a level that approached significance (P<.094). FG patients were significantly less likely to require a postoperative wound vacuum-assisted closure (VAC) (FG: 16.7%; MF: 76.7%; P<.001) and required a significantly lower number of 30-day postoperative visits (FG: 1.5±.78 visits; MF: 2.5±.03 visits; P<.001). The MF group had higher mean aggregate charges ($211,090) compared with the FG group (mean: $149,907), although these were not statistically significant (P>.05). Conclusion: The use of FG for STSG shows comparable clinical outcomes to MF, with a significantly decreased need for postoperative wound VAC, the number of 30-day postoperative visits, and a lower wound-adjusted operative time.
