title: [Clinical observation of the effect of crystallitic dermabrasion on skin superficial scars].
abstract: OBJECTIVE
  To observe the changes in histopathology and clinical effect after the treatment of superficial scars in human faces and exposed parts of human extremities with crystallitic dermabrasion.
  
  
  METHODS
  The machine made in Italy can produce the high speed crystallite to the surface of the scar, resulting in the alveolate wounds. At the same time the crystallitic drill make the accidental scar smooth.
  
  
  RESULTS
  Two thousands and five hundreds and thirty eight suffers were treated for 2-10 times. The appearance of the scars was improved. Six patients complicated with milium, Eleven got hypopigmentation, eight got hypomelanotation. Eighty percent patients of this groups got pigmentation after the treatment. This signs disappeared or improved after 2-6 months. Histopathology demonstrated the scar area became small, the fibroblasts increased remarkably and the collagenous fiber arranged regularly. The cells in the stratum spinosum proliferated actively.
