title: [Digital evaluation of breast symmetry with 3D scanning technique].
abstract: OBJECTIVE
  To establish a standard method for digital evaluation of breast symmetry with 3D scanning technique.
  
  
  METHODS
  From January 2009 to July 2010, 167 patients received 3D scanning before breast augmentation. The coordinate system was established and the 3D reconstructed breast models were analyzed by software. The discrepancy of nipple level, the distance between nipple to midline, inferior mammary fold location, breast width, breast projection, breast volume and anterior chest wall projection were measured.
  
  
  RESULTS
  The mean discrepancy of nipple level, the distance between nipple to midline, IMF level, breast width, breast projection and anterior chest wall projection were (4. 8 +/- 3.9) mm, (4.5 +/- 3.4) mm, (4.6 +/- 3.7) mm, (4.8 +/- 2.9) mm, (5.4 +/- 3.9) mm and (4.8 +/- 3.3) mm, respectively. The mean difference of breast volume was (51 +/- 44) ml. The incidence of significant asymmetry was 73% (122/167)in nipple position, 95% (159/167)in breast shape, 38% (63/167)in anterior chest wall projection.
  
  
  CONCLUSIONS
  3D scanning technique can provide an accurate 3D measurement of breast. A thorough and objective evaluation of breast symmetry can be achieved.
