Skin GraftingSkin embeding, or, the shifting of shin and other underlying tissues types to another location has been used for near three thousand years. It originally began with the Hindu Tilemaker Caste System where spit out grafting was used to reconstruct noses that had been amputated as punishment. Over time, it evolved, and in this contemporaneous age we possess two major means by which to transplant skin split-thickness skin grafting and full-thickness skin grafting. In split-thickness skin grafts, the skin graft includes only the epidermis and a portion of the dermis. The thickness of the slice up can be broken down further into a keen mold (.008-.012 mm), a medium storey (.012-.018 mm), and a thick layer (.018-.030 mm). This type of skin grafting is used primarily when cosmesis, or, the concern for the port of the patient, is not a key concern, or when the defect is too enormous for the use of a full-thickness skin graft. Split-thickness skin grafts are employed in various situations including chronic non healing cutaneous ulcers, temporary insurance coverage to go forth for the observation of a possible tumor reoccurrence, surgical correction of depigmenting disorders, and coverage of burn areas to accelerate wound healing and reduce the loss of fluids. The modus operandi for harvesting and transplanting split-thickness grafts begins with the measurement of the skin defect. A purse-string placed more or less the defect reduces its size and thus also the size of the graft that must be harvested from the bestower. Effective donor sites include thighs, buttocks, and upper arms. Then the donor site is lubricated with sodium chloride and a sterile tongue depressor is placed across the donor site to create a monotone surface. The surgeon then applies the dermatome to the donor site and slices off the necessary layer of skin. The newly harvested skin is placed in a sodium chloride firmness and is prepared to be meshed. Meshing is advanta geous when one wants to increase the symmetry of the skin graft. By placing it in the mesher, the graft becomes flatter and obtains a ball field plate appearance. Keep in mind that while it is acceptable to pare the graft to fit the recipient site, it is better to have some co-occur between the donor tissue and the recipient bed. The slight-thickness skin graft is secured by staples and a bolster may be applied to encourage graft apposition to the recipient bed, to decrease shearing forces, and to maintain a moist environment for the graft.
