Since microskin grafting was used in 1985,23 years have passed. Many patients with extensive third degree burns were cured by the technique. Some progresses and further improvements are discussed.(1) Several kinds of apparatus were devised to cut skin into mierografts with good results.(2) The orientation of each skin granule and even dispersion of micrografts are very important. Some methods to spread micrografts on wound were compared with one another, the technique of flotation in saline and transferring them on silk texture is still the best way.(3) Many outside materials other than silk can be se lected, among them the homograft is commonly used, but it has some shortcomings.(4) The technique should be further improved. Stem cell transplantation may be expected as a new way to help heal extensive wounds.
