=b. Autodermic Skin-grafting.=—Larger pieces of skin may be excised from selected parts of the body, preferably the outer side of the arm, and utilized to cover the entire defect. The piece of skin is cut about one third larger than the size and shape of the area to be covered. This method was first introduced by _R. Wolfe_ in 1876, and gives splendid results. He advises removing all subcutaneous adipose tissue from the graft by gently cutting it away with fine scissors or the razor, and then loosely suturing the flap to the skin surrounding the denuded defect. Granulating surfaces must first be freed of their loose superficial layers with a sharp curette and the bleeding controlled by sponge-pressure before the flaps are placed. The edges of the wound made by the excision of the flap are simply sewn together, or one of the plastic methods may be used to accomplish the same. Unfortunately these flaps, if they thrive, contract, leaving uncovered spaces, which must be treated separately or allowed to granulate. The dressing in this case is the same as in the Reverdin process. _F. Krause_, of Altoona (1896), advocates the use of freed flaps from which the subcutaneous adipose tissue has not been removed, holding that in the healing of such there is less contraction to follow. The success in both of the above methods depends upon an early vascular connection, as considerable nutrition is necessary to supply their want. The blood dressing has aided much in bringing about a happy result. The latter is continued in the manner described for about ten or twelve days, when the grafts may be allowed to depend upon their own circulatory supply. The parts must, in the meantime, be kept at rest and all undue pressure is to be avoided. These grafts, while becoming organized, change in color more or less from a light gray to a bluish gray and shed off their epitheliar layers, while the _cutis vera_ remains, rebuilding its squamous covering eventually and leaving the surface quite normal. At times small points of the flap, where subjected to undue pressure or interference, will turn dark and break down, sloughing away and leaving the granulating surface exposed. These areas are, however, soon recovered by skin cells being thrown out from the infral edges of the graft. Often the use of the nitrate-of-silver stick, applied gently at various tardy points, will hasten the process of repair.
