Breast Reconstruction Techniques: Understanding Your Options
Breast reconstruction can be performed using an implant, the patient’s own tissue, or a combination of both.
There is no single technique that is best for every patient. The choice depends on the type of mastectomy, whether radiotherapy is required, the quality of the remaining skin and soft tissues, previous surgery, available donor sites and the patient’s priorities.
Implant-based breast reconstruction
Implant reconstruction uses a breast implant to recreate the volume and shape of the breast directly after mastectomy. It can be performed either directly with a permanent implant or in two stages using a temporary tissue expander.
-
When the definitive implant cannot or should not be placed immediately, a temporary tissue expander can be inserted at the time of mastectomy.
The expander preserves or progressively recreates the breast envelope.
Expansion is performed gradually after adequate wound healing.
Once the desired volume and tissue conditions are achieved, the expander is replaced by a permanent implant.
The timing of the exchange depends on healing, the oncologic treatment plan and whether radiotherapy is required.
-
This may be considered when:
The mastectomy skin envelope is well preserved and adequately vascularized.
The desired breast volume can be reconstructed without excessive tension on the skin.
A skin-sparing or nipple-sparing mastectomy is oncologically appropriate.
Patient anatomy, smoking status and the anticipated cancer treatment (no radiotherapy) are compatible with implant reconstruction.
The implant may be placed beneath the pectoralis muscle (partial or total subpectoral) or, in selected cases, above it (subcutaneous).
The main advantage is avoiding the expansion process and potentially completing the principal reconstruction in one operation. However, secondary procedures such as fat grafting, scar revision or surgery to improve symmetry may still be useful.
-
Women with high risk of post-operative radiotherapy as this options preserves the native breast skin and minimizes unaesthetic scarring
An inflatable breast implant is inserted underneath the muscle and marginally inflated
After 2 weeks, pathology reports will dictate the need for radiotherapy.
If no radiotherapy indicated, definitive reconstruction with implants or flaps is undertaken
If radiotherapy is indicated, the expander is left deflated through chemotherapy and radiotherapy plus 4 weeks recovery where the expander is inflated until the desired volume over 3 months and definitive reconstruction with implants or flaps is undertaken
What are the limitations of implant reconstruction?
Implant reconstruction generally involves a shorter operation and avoids surgery at a separate donor site. However, an implant is a prosthetic device and does not behave like living breast tissue.
Potential long-term considerations include implant-related complications:
Capsular contracture
Implant rupture or displacement
Infection or implant exposure
Visible implant edges or rippling, particularly in thin patients
Changes in breast shape over time
The possibility of further implant surgery during the patient's lifetime
Radiotherapy can increase the risk of capsular contracture, wound problems and implant-related reconstructive failure. For this reason, the anticipated need for radiotherapy is an important part of reconstructive planning.
Fat grafting can sometimes be used alongside implant reconstruction to improve soft-tissue coverage, contour irregularities and the transition between the reconstructed breast and chest wall.
Autologous breast reconstruction
Autologous reconstruction uses the patient's own tissue to reconstruct the breast.
Skin and fat are transferred from another part of the body while preserving or restoring their blood supply. Depending on the technique, muscle may or may not be included.
The principal advantage is that the reconstructed breast consists of living tissue. It can provide a soft breast mound that changes with the patient's body over time and avoids dependence on a permanent breast implant.
The trade-off is a longer and more complex operation, together with a scar and potential complications at the donor site.
DIEP flap breast reconstruction
The tissue resembles that removed during an abdominoplasty, but the operation is fundamentally different because the tissue is transferred together with the blood vessels that keep it alive, and reconstruct the breast mound.
-
Skin and fat are harvested from the lower abdomen.
The perforating blood vessels supplying the tissue are carefully dissected through the abdominal muscles.
The tissue is transferred to the chest.
Its artery and vein are connected to recipient vessels in the chest using microsurgery.
The transferred tissue is then shaped to recreate the breast mound.
-
Uses the patient's own skin and fat.
No permanent breast implant is required.
Provides a soft reconstruction that can change naturally with changes in body weight.
Particularly useful when healthy vascularized tissue is needed after radiotherapy.
The lower abdominal donor site is closed in a manner similar to an abdominoplasty.
-
DIEP reconstruction is a major microsurgical operation and requires a suitable abdominal donor site.
Potential considerations include:
Longer surgery and hospital stay than implant reconstruction
Abdominal and breast scars
Seroma or wound-healing problems
Abdominal weakness or bulging
Fat necrosis within the reconstructed breast
Partial flap necrosis
Latissimus dorsi flap reconstruction
The latissimus dorsi (LD) flap uses skin, fat and part or all of the latissimus dorsi muscle from the back. Unlike DIEP reconstruction, the tissue usually remains attached to its original blood supply and is rotated from the back to the chest. Microsurgical vessel connections are therefore generally not required.
-
When additional healthy tissue is required over the chest.
In selected patients who have undergone radiotherapy.
When abdominal free-flap reconstruction is not appropriate or desired.
As a salvage option after previous reconstructive problems.
When an implant requires additional vascularized soft-tissue coverage.
Because the flap often does not provide enough volume to reconstruct the entire breast, it may be combined with an implant or with fat grafting.
-
The operation creates a scar on the back and sacrifices at least part of the latissimus dorsi muscle.
Most patients compensate well for the loss of the muscle in normal daily activities, but shoulder and back function remain relevant considerations, particularly in physically active patients.
Seroma at the back donor site is also relatively common.
