Breast implants have varying filler, shapes and surface profiles. The right one for you will depend on the look you want to achieve and factors such as height and body shape.

Breast implants can be used to:

  • Enlarge small breasts
  • Restore volume after weight reduction or pregnancy and breastfeeding
  • Even up asymmetric breasts
  • Reconstruct after mastectomy or injury

CosMedicWest typically offers round and shaped/anatomical breast implants that are textured and gel filled.

Filler Types

The main types of breast implants used in Australia are:

  • Saline – a silicone envelope filled with varying amounts of sterile salt water (saline). This can affect shape, firmness and feel.
  • Silicone – a silicone envelope filled with an elastic gel that feels like natural tissue.

Gel implants are primarily used to achieve more natural results and have less risk of specific complications. Saline (water filled) implants have a greater risk of rippling where a wave like irregularity can either be seen or felt. To reduce this risk, saline implants are overinflated by 10%, which can make them feel firmer. They also have a life expectancy of seven years and may deflate and need to be replaced.

Breast implants are not guaranteed to last a lifetime and future surgery may be required to replace one or both.


Surface profiles can be either textured or smooth. We only recommend the use of textured (rough surfaced) breast implants as they are least likely to harden, tend to be more natural and mobile, but not too floppy. They also do not need to be massaged every day for the rest of your life.

Smooth implants have a significantly higher rate of going hard (capsular contracture) and need massaging every day. They also tend to be more floppy and, in some cases, may slide out towards your armpits as you lay back. We have also seen that smooth implants, in the longer term, can push in to different areas and result in odd shapes and ‘bottoming out’.


Breast implants can be round or anatomical/pear shaped. The shape to best suit you will depend on your current breast amount, shape, thickness of your tissues and your desired outcome.

In general terms, shaped are used for thin patients with little or no breast tissue. Round implants are best for women who have some tissue but it is ski-jump in shape.

With any patient, it also depends on the size and shape you want to achieve. The recommended shape will be determined in consultation with your surgeon.
