SIEF
(Simultaneous Implant Exchange with Fat Grafting)

My Approach

Many women choose to remove their breast implants - whether due to discomfort, capsular contracture, aesthetic changes, or simply a desire for a more natural feel. Simultaneous Implant Exchange with Fat Grafting (SIEF) replaces the implant with the patient’s own fat in the same operation, restoring shape and volume naturally without the need for new implants.

SIEF can also be used after breast reconstruction with implants, when patients experience implant-related issues or prefer a more natural long-term solution. By replacing the implant with one’s own tissue, SIEF offers a softer, warmer, and more natural result that continues to age harmoniously with the body.

Planning & Technique

During SIEF, the capsule surrounding the old implant is removed as completely as possible to restore a healthy, flexible pocket. In patients with symptoms such as discomfort, tightness, or systemic concerns attributed to their implants, a more extensive capsulectomy may be performed as part of a comprehensive management plan.

Fat is then gently harvested from areas such as the abdomen or thighs, purified, and carefully grafted into the breast to recreate volume and contour. This method restores natural shape and improves comfort without introducing new implants.

Recovery & Expectations

Most patients resume light daily activities within a week or two. Swelling or mild bruising may occur around the liposuction and grafting sites, but typically subsides within two weeks. Light exercise can resume after three to four weeks, while more strenuous activity should wait until about six weeks.

Support garments are recommended during recovery to help maintain shape as the tissues settle. The grafted fat gradually integrates over several months, resulting in a soft, natural contour that ages naturally with the body.

Complementary Procedures

SIEF can be combined with:

Nanofat rejuvenation - to improve skin texture and tissue quality
Liposuction - as part of overall body contouring, using harvested fat for both enhancement and balance
