title: [Premovement of polyacrylamide hydrogel (PAAH) from breast through submammary fold incision].
abstract: OBJECTIVE
  To investigate the bad effect of breast augmentation with PAAH injection and the technique to remove PAAH from breast effectively and safely.
  
  
  METHODS
  43 cases (86 sides) underwent operation to remove the PAAH from breast through submammary incision, followed by dressing with pressure for 3 days. The patients received colored doppler ultrasonography and immunologic test before and 3 months after operation.
  
  
  RESULTS
  Postoperative ultrasonography showed residual PAAH in breast in one case. Among the 20 cases who had preoperative breast pain, the pain relieved completely in 10 cases and improved in the other 10 cases. All the patients had some abnormal results in immunologic test which improved 3 months after operation.
  
  
  CONCLUSIONS
  Breast augmentation with PAAH injection can result in breast pain and other complications. It may also have bad effect on the immune system. PAAH should be removed as soon as possible. The technique through submammary incision to remove PAAH is one of the safe and reliable methods.
