    Abstract:
    BACKGROUND: Patients suffering major burns of more than 50% total burn surface area lack an adequate skin graft donor site to resurface extensive burn wounds and usually need widely meshed autografting and allografting. Anything over the 3:1 expansion ratio is strongly associated with low graft take, poor or delayed epithelialization, and hypertrophic scarring. METHODS: In this study, both autografts and allografts were expanded at a 4:1 ratio. We aimed to use skin grafts effectively and to decrease the morbidity due to graft harvesting. Nine patients with major burns were treated with this method. Graft gain ratio and percentage of actual expansion to predicted expansion were calculated. RESULTS: Ten auto-allografting procedures were performed on a mean of day 16. Graft take was over 95% successful. Five patients survived, and four patients died. The mean total burn surface area was 58.8% in patients who recovered, and 77.5% in the patients who died. The graft gain ratio was 74.8%. The actual expansion rate was 43.7% of the predicted expansion rate. CONCLUSION: In this study, we demonstrated that the donor site morbidities were reduced and successful epithelialization was completed on the eighth day after using both autograft and allograft meshed with a 4:1 ratio.
