Breast Augmentation

Breast augmentation is a commonly performed procedure that increases the size of the breasts. This surgery aims to increase the breast size so that they are more in proportion with the rest of your body, or to restore fullness to the breasts that is lost after breast feeding. This can improve your body image and restore your self confidence.

Implant placement

Breast implants may be placed via a variety of surgical incisions which include in the fold below the breast (most common), around the nipple or in the armpit. The implants can be positioned either underneath the pectoral muscle or above the muscle directly beneath the breast tissue. If you are quite thin then it is best to position the implants under the muscle so that the edge of the implant is less likely to show. Dr Lotz can advise you which positioning would be the most appropriate in your case.

Silicone on Saline implants?

The most commonly used breast implants these days are made of silicone. Despite the concerns over silicone breast implants in the 1970’s, studies have since shown that there is no increased risk of the development of cancer, immunologic or neurological problems associated with the use of silicone breast implants. Modern silicone implants are made of a “cohesive gel” which is a bit like set jelly and will hold its shape even when it is cut in half. This gel is covered with a thick, textured envelope that can help to decrease the risk of capsule formation around the implant (which may cause distortion and hardening of the implant).

Implant shape

Breast implants come in either round or “anatomical” shape. The anatomical implants are shaped like a teardrop when seen from the side, which attempts to mimic the normal shape of a breast. Dr Lotz can advise the pro’s and con’s of each of these choices, and help you decide which is most suitable for you.

The surgery

Breast augmentation is performed under a general anaesthetic, and takes around an hour. You will usually stay overnight in hospital, but some patients opt to be discharged on the same day. You do not usually require any drains or special dressings following the operation.


Your breasts are usually a bit swollen and tender after the surgery, and may feel a bit tight for a few days. There is often some numbness of the breasts which resolves in the following weeks. It is usually best to avoid any strenuous activity for a month, but gentle exercise can be resumed after a couple of weeks. Keeping surgical tape on the scars for 3 months can help to minimise the scarring for the best possible aesthetic result. It is important to continue regular breast self-examination after the surgery. Patients with breast implants are still able to have mammograms.
