Securing skin grafts: A network meta-analysis.

BACKGROUND

Skin grafting is one of the most common procedures in plastic surgery. However, there are no defined guidelines for optimal fixation. The aim of this network meta-analysis (NMA) was to consolidate existing evidence by comparing various graft securing methods and determining the most effective approach for clinical practice.

METHODS

An NMA was conducted using a predetermined protocol after searching several electronic databases from inception to October 2023 for studies examining skin grafting fixation outcomes in adults.

RESULTS

A total of 27 studies were included in the analysis involving 1937 patients. Negative pressure wound therapy (NPWT) was the only method to significantly improve graft take percentages in comparison with the other modalities, whereas tie-over bolster (TOB) provided the worst results in take rates when examined as events. Fibrin glue (FIB) and TOB reduced hematoma and seroma rates when data were investigated in conjunction.

CONCLUSIONS

NPWT appears to be the most effective for skin graft adherence as opposed to traditional techniques. Its cost-effectiveness remains unclear, as NPWT is a relatively costly intervention compared with other methods. FIB and TOB are methods that can serve as a method of reducing hematoma and seroma rates in patients at high risk of bleeding.
