Purpose: To treat burn and burn scar contracture, many types of dermal substitutes have been manufactured and used recently. Allogenic dermis is known to have best cellular affinity to the host, but it is the thinnest product among artificial dermis. Processed thick allogenic dermis (Allocover?) has been developed and applied to overcome the problems of preexisting materials as a permanent dermal substitute.
Methods: From June 2007 to May 2009, we have grafted thick acellular human dermal allograft with thin split-thickness skin graft on burn wound and burn scar contracture of feet and legs in 14 patients who had hypertrophic scar, joint contracture and various skin defect areas. Intraoperatively, we fixed spilt thickness skin graft to artificial dermis with suture fixation for avoiding the mobilization between them.
Results: Thirteen patients out of 14 patients had no problem. One patient underwent partial skin loss and secondary healing process. During the 18 months of follow up period, no contracture recurrence or skin loss was observed.
Conclusion: The thick acellular human dermal allograft (Allocover?) could be very useful in the management of skin loss and burn scar contractures. Its vascularization has occurred fast enough that wounds can be covered in an adequate layer of dermal augmentation with minimal contracture and good cosmetic results.
