ABSTRACT
Chronic wounds come from a retardation or wound healing inefficiency, traumatic or from basal diseases. The allograft, a possibility of treatment of major burns and extensive dermal wounds, allows a faster recovery of damaged areas favoring autograft. Studies point to a shorter hospitalization time, with less complications and death with allograft alone. In addition, the use of allograft reduces the epithelization time of injured areas, such as traumatic injuries and burns, up to 40%. This is due to the replacement of the allograft keratinocytes, the migrants from the edges or deep areas of the wound. Because of the high efficiency associated with easy use and storage, the customary use of allograft can be applied at a low cost and risk to the patient, even in outpatient treatment.
