Introduction: The aim of this study is to report outcomes and complications in a series of patients suffering soft tissue defects incritical areas treated using an acellular dermal matrix. Materials and Methods: A retrospective review of patients with soft tissue coverage deficits in critical areas treated with acellular dermal matrix in our center over a five-year period was conducted. The preoperative variables analyzed were: age, sex, comorbidities, number of previous surgeries, size and characteristics of the critical area and cause of the coverage defect. The intraoperative variables analyzed were: size of the dermal substitute used, surgical time and complications. The postoperative variables were: incorporation of the dermal substitute, time elapsed until the placement of the skin graft, and postoperative complications. Results: The initial diagnoses were tumor (3 patients), acute trauma (3 patients) and sequelae of compartment syndrome (2 patients). The soft tissue defect was located in the leg (3 cases), in the hand (2 cases), in the thigh (1 case), in the forearm (1 case) and in the foot (1 case). In 5 cases the critical zone was characterized by tendon exposure with loss of peritenon; in one case bone exposure and loss of periosteum; in one case exposure of nerve graft and in one case exposure of osteosynthesis material. Three complications were recorded. Conclusion: Dermal substitutes are characterized by their versatility. This technique can provide protection in situations of bone exposure, in addition to providing a sliding plane in case of tendon exposure. In situations of failure or impossibility of performing a biological reconstruction, dermal substitutes have a role within reconstructive options.
