The prognosis of extensive 3rd degree burns has been considerably improved by the use of homografts pierced with holes to allow application of small portions of autografts. The histological appearances after successful grafting of the skin are described in detail. Grafts of this type allow maximum economy of remaining healthy skin, and this technique is a very great improvement over Mowlem-Jackson's procedure. Successful results have been obtained in 3rd degree burns covering 90% of the body surface.
