A breast implant is a prosthesis used to alter the shape and size of woman’s breasts (known as breast augmentation, breast enlargement) for cosmetic reasons to reconstruct breast.(e.g. after mastectomy or to correct congenital chest wall deformities)


There are following types of breast implants:

  1. Saline filled implant- They have silicone elastomer shell filled with sterile saline liquid. 
  2. Silicon-gel- filled implants- They have silicone shell filled with viscous silicone gel.It is a polymer of silicon oxygen with methyl side group known as Dimethylsiloxane.


  • Minimum solubility of silicon.
  • Excellent viscosity.
  • Excellent feel to breast. 
  1. Double lumen implant- Consists of concentric balloons containing silicone in one   chamber and saline in other or vice versa.
  2. Alternative fillers implant- Polyvinyl pyrrolidone low molecular weight bio-oncotic gel implant, Triglyceride filled trilucent implant, Hydrogel implant filled with polysaccharide and water withdrawn from market because of high complication rate.
  3. Polyurethane covered implant-Silicone gel implant covered with polyurethane foam. Less incidence of capsule contraction, but chances of Polyurethane breakdown and Foreign body giant cell reaction. .

Indications & Contradiction

Breast implants are used primarily for:

  1. Primary reconstruction.( to replace breast tissue that has been removed due to cancer / trauma or that has failed to develop properly due to severe breast abnormality such as tuberous breast deformity, Congenital absent breast, Sex change, Female glandular hypomastia.)
  2. Revision- Reconstruction ( revision surgery to correct / improve result of an original breast reconstruction surgery, Post mastectomy reconstruction.)
  3. Primary Augmentation (to increase breast size for cosmetic reasons.)
  4. Revision- Augmentation ( revision augmentation to correct / improve result of an original ( breast augmentation surgery.)


1.   Malignancies.

2.   Bleeding disorders.
