Introduction: In large full-thickness skin defects, donor site morbidity limits the available thickness and surface of skin autografts and therefore only split-thickness skin grafts are possible for reconstruction. Dermal equivalents can be added to these split-thickness grafts to acquire an anatomically better skin reconstruction. Glyaderm is a human derived, acellular dermis and up until now has only been used in a two-staged procedure. This report describes results of a case series using Glyaderm and split-thickness skin grafts in a single-staged procedure.
Methods: Glyaderm was introduced in 2017 in Radboudumc (Nijmegen, The Netherlands). Glyaderm and autologous split-skin grafts were simultaneously applied to the wounds. In cases with large wound surfaces or wounds covering highly mobile areas, negative pressure wound therapy was additionally applied. The first ten cases were followed with regular intervals post-operatively, assessing graft take, scar appearance, post-operative wound problems and re-interventions.
Results: Patients were aged 3 weeks to 76 years-old. Treated skin surface varied from 1-16% total body surface. Wounds resulted from trauma (n = 4), burns (n = 4) or soft tissue infections (n = 2). Follow-up varied from 4 months to 1.5 years. No complications occurred after surgery. Average take rate was 98%. Two patients had a later re-intervention to further improve the aesthetic appearance of the scarred area.
Conclusion: Our first results with the application of Glyaderm in a single-staged procedure provided good healing, graft take and scar appearance. Glyaderm was found a suitable dermal substitute in the treatment of full thickness wounds.
