The method of transfer of fat to the breast varies between surgeons. A uniform method has not been defined as yet because this technique is still new and is changing as we speak. However, certain principals for transfer have been defined. Using small gauge cannulas, placing the fat with multiple passes, and with small quantities at a ttime is considered by most to be essential in good outcome. Smart lipo or other types of liposuction machines are not as important to the outcome as the knowledge and expertise of the surgeon. Just remember that this is still in experimental stages and you must follow-up with your surgeon to make sure you do not have problems with your breast.Good luckSaeed Marefat, MD
