Delayed skin grafting.

Abstract

The use of skin grafts on granulating wounds is an established practice. Delaying the application of a full- or split-thickness skin graft may be an advantageous alternative method of surgical reconstruction in selected cases. Partial healing by secondary intention is useful for filling in deeper defects and usually produces a wound that is much smaller and of more normal contour than the original defect. Contraction of the graft bed is markedly influenced by location, tissue laxity, surface tension lines, motion, and wound geometry. Proper wound care, correct surgical preparation of the defect, and timing of the graft procedure are all important considerations in maximizing the overall result. Through-and-through defects and wounds produced over areas with little underlying support (eyelids and lip) often need flap reconstruction or immediate grafting to prevent undesirable functional and cosmetic results. By combining delayed healing and conventional reconstructive techniques, major tissue loss can often be restored while minimizing patient morbidity.
