529 Safeguarding Skin Grafts: A 21st Century Algorithm for Fixation Techniques

Aim Effective skin graft fixation is fundamental in preventing sheering forces, seroma and haematoma from compromising graft take. However, determining the ideal method of graft fixation remains a contentious subject. Currently, there is significant variation in fixation techniques used, based not only on clinical requirement, but also surgeon preference. Evidence-based recommendations are necessary to guide the decision-making process. Method We undertook a PRISMA-based assessment of the literature to define all fixation techniques and analyse their outcomes. Inclusion and exclusion criteria were composed. A search of Medline and Embase was performed, yielding 399 articles. After abstract screening, 96 were included for qualitative data analysis. Results Nine fixation techniques were identified: ‘tie over bolster’, ‘staple fixation’, ‘simple dressings’, ‘quilting sutures’, ‘re-look methods’, ‘foam sponge bolster’, ‘adhesive glues’, ‘negative pressure wound therapy’ and ‘less common techniques. We analyse the available evidence for each technique, identifying 13 studies with level I/II evidence. We summarise the research that underpins these nine categories, proposing an algorithm to facilitate technique selection based on anatomical and patient-specific factors. Conclusions An array of skin graft fixation techniques are used in plastic surgery, without clear guidelines. To our knowledge, this is the first time all fixation techniques have been defined. Our suggested algorithm is intended to aid surgeons in selecting an appropriate fixation technique and should be challenged by future research, particularly randomised control trials.
