Fat transfer breast augmentation is a procedure aimed to increase breast size by injecting fat removed from another part of the body. This surgery usually allows restoring one cup size of volume (whereas it is possible to gain two cup sizes with breast implants).

  • Your breasts are too small (mammary hypotrophy)
  • You experienced breast sagging after breastfeeding and pregnancy rembourrés
  • You systematically wear padded bras
  • Your breasts are asymmetrical
  • Your breasts have a deformity (Poland syndrome, tuberous breasts)

It is important for young women to reach milestones in growth and physical maturity before considering surgery. Indeed, there is often a variation in body weight and size and hence the breast shape. It is also recommended to wait until puberty before considering surgery.
To consider having a breast augmentation in the best possible conditions, it is important that your weight be stable. In fact, variations in weight can alter the result of the surgery, as well as excess weight increases the risk of post-operative complications. Of course, each situation should be discussed with your surgeon who will be best able to advise you.
Lipofilling surgery may be contraindicated in some cases, especially in patients with a personal or family history of breast cancer. Currently, this surgery is subject to strict regulation in Switzerland and the Swiss Plastic Surgery’s recommendations should be followed. Dr Thomet will answer your questions and advise you whether you are a good candidate for surgery.

Scars position

The surgery leaves only small scars of just a few millimeters in the fat collection area, not in the breast area.


The first consultation with Dr Thomet will allow you to get to know your surgeon, talk about your personal situation and present your expectations. In order to complete your medical record, she will ask about your medical history, previous operations you may have had, and the list of medicines and allergies.
A physical exam will be carried out and your measurements taken, and in some cases photos will be taken, which will remain confidential and will only be used for your medical records. At the end of the consultation, Dr Thomet will give her diagnosis and will advise you whether you are a good candidate for surgery. She will explain to you the technique she plans to use, the position of the scars, the recovery time and the risks of complications.
After you have had time to think it over, a second appointment will be arranged in order to answer your questions, choose the implants and set a date for the surgery. A radiologic exam (mammography and/or breast ultrasound) dating since less than a year is required before any surgery.


Fat transfer breast augmentation is regarded as an aesthetic surgery. As a result, it is not covered by health insurance.
The surgery is rarely covered by health insurance (in the case of a congenital malformation such as Poland syndrome and tuberous breasts). Your surgeon must make a prior request by sending a letter with your photos.
Otherwise, a cost estimate will be forwarded to you after the first consultation.

Type of anaesthesia

Fat transfer breast augmentation is a surgery that requires general anaesthesia. A preoperative consultation with an anaesthesiologist will be therefore organised before surgery


Fat transfer breast augmentation does not usually require hospitalisation, one-day outpatient care is sufficient.

Postoperative period

When leaving the clinic, you will just have dressings which will be changed the following week for the first time at the practice. You are allowed to shower around 2 days after surgery. It is not recommended to wear bras for 2 weeks.
However, you will need to wear a compression garment for 6 weeks depending on the area of fat collection, in order to reduce swelling.


Driving after surgery is not recommended. Activity resumption may be considered after 1-2 weeks depending on the type of activity. It is necessary to wait 6-8 weeks before doing sports.
