title: [Analysis of complications induced by polyacrylamide hydrogel injection for augmentation mammaplasty].
abstract: OBJECTIVE
  To analyze the complications induced by polyacrylamide hydrogel injection for augmentation mammaplasty, explore the reason of the complication.
  
  
  METHODS
  Twenty three patients with complications after polyacrylamide hydrogel injection were classified by signs and symptoms, ultrasound and pathologic examinations were made.
  
  
  RESULTS
  The main complications were pain, hard nodule, asymmetry and breast deformation. The injected material was distributed diffusely behind gland, in gland, in muscles subcutaneous, even out of breast, caused some pathologic changes and it's hard to be cleaned completely from normal tissue.
  
  
  CONCLUSIONS
  The complications were caused mainly by incorrect manipulation during operation, others might be relative to the injected material. The reliability of this injection method for augmentation should be cautiously observed.
