title: [Lower capsular contracture of miniprostheses as compared with the conventional silicone implant].
abstract: OBJECTIVE
  To determine if miniprostheses would form a capsule of significantly different biophysical, biochemical and histologic properties than the conventional silicone implant.
  
  
  METHODS
  Four miniprostheses (experimental group) and one big silicone implants (control 1 group) were separately implanted beneath the panniculus carnosus muscle of 30 rabbits. After 3 months, measures related to contracture and capsular histology were performed on anesthetized animals.
  
  
  RESULTS
  Baker ranking, capsular incision width and capsular thickness of the control groups were evidently higher than that of experimental groups (P < 0.01). Implant compression of the control groups was evidently lower than that of the experimental group. Histology revealed a thinner, more flexed capsule around the miniprostheses as compared with big silicone implants.
  
  
  CONCLUSIONS
  The miniprostheses form a looser and thinner capsule than the conventional silicone implant.
