Breast Reconstruction After Mastectomy | Implants and own-tissue options

Implant reconstruction uses a breast implant, sometimes after tissue expansion, and may suit women wanting fewer operative demands. Flap reconstruction uses your own tissue, often from the abdomen, and may be preferred when radiotherapy is involved because implant-based reconstruction has higher complication rates in that setting. A systematic review found flaps had higher satisfaction and lower long-term failure, while implants had shorter operative times and no donor-site morbidity. Autologous reconstruction needed more secondary procedures for asymmetry in unilateral cases. Any reconstruction can fail if healing is poor; implant failure can often be revised with another approach. The decision depends on anatomy, comorbidities, radiotherapy and preferences, with multidisciplinary shared decision-making.

Reconstruction after mastectomy can use an implant, your own tissue, or both. The exact option depends on factors such as radiotherapy, opposite breast size and shape, available donor tissue, and practical considerations. A tissue expander is often part of two-stage implant reconstruction: it is placed under muscle and gradually filled, usually weekly, to stretch mastectomy flap skin safely. If flap blood supply is significantly compromised, a deflated expander may be safer than direct implant placement; if flaps are well supplied with blood, direct-to-implant reconstruction may be considered. Expanders are temporary devices and are not intended to remain beyond about six months, although some newer expanders can remain permanently once expansion is complete.

Prepectoral reconstruction was developed to reduce muscle-related problems of subpectoral or dual-plane placement by moving the implant to the subcutaneous plane. Because the pectoralis major is not dissected or elevated, prepectoral placement can avoid animation deformity, pain and muscle spasm sometimes reported with subpectoral placement, and may look more like a native breast. Modern prepectoral reconstruction relies on adequate mastectomy skin-flap blood supply and supportive techniques such as acellular dermal matrix, fat grafting and cohesive implants; it is not suitable for every patient. Later stages, such as implant exchange, fat grafting and nipple reconstruction, are adjusted to the individual, and radiation or chemotherapy can change timing or feasibility.

In a TRAM flap, the rectus abdominis muscle carries blood supply to abdominal skin and fat; in a DIEP flap, the surgeon separates the deep inferior epigastric vessels from that muscle, so the muscle stays intact. This muscle-sparing difference is why DIEP flaps are linked with less donor-site problems such as hernia, asymmetry and muscle weakness, while still providing well-vascularised abdominal tissue. Lower abdominal autologous flaps can create natural, lasting breasts with high long-term satisfaction, but they involve donor-site morbidity and longer, more complex surgery and recovery than implant-based reconstruction. Autologous reconstruction also avoids implant problems such as capsular contracture and device failure.

The flap brings skin, fat and muscle from the middle and side of the back on its blood supply. It is used in immediate or delayed reconstruction, and sources note it is often chosen after radiotherapy or failed reconstruction, where autologous tissue is preferred over implants. It can cover an implant or expander, and may suit a taut skin envelope with thin tissue; capsular contracture rates are lower than implant-only reconstruction because soft-tissue coverage is better. Best candidates also depend on body fat, opposite breast shape, back fullness, whether the muscle is functioning before surgery, and on individual anatomical factors and aesthetic goals.

Reconstruction may use an implant, your own tissue, or both. When abdominal tissue is limited, tissue from the back or buttock area may be considered. The choice depends on available tissue, prior abdominal surgery, radiotherapy, breast size and shape, donor-site healing, recovery time, cancer treatment, local availability and your preferences and overall health. Thin patients may have limited skin stretch and soft tissue, so achievable volume and donor-site closure need careful discussion. Autologous reconstruction can improve satisfaction, but not everyone is suitable. Implants may suit small to medium breasts without radiotherapy, while combined approaches can help medium to large breasts. Patient preference matters, but safety, reliability and surgeon experience also guide planning.

Preoperative CT angiography images of the donor site and thoracic region are routinely obtained for perforator mapping and recipient-vessel evaluation. After flap markings and grid localization of perforating vessels for the anticipated defect, the dominant perforator is confirmed with a unidirectional handheld Doppler. An SIEA flap uses a different vessel set, but those vessels are often inadequate or absent. After anastomoses, perfusion is assessed by capillary refill of about 2–3 seconds, warmth and bright red bleeding from the flap edges; handheld Doppler may confirm a signal, while venous outflow is judged by flap appearance, with congestion prompting consideration of SIEV augmentation.

Skin-sparing mastectomy removes breast tissue while preserving much of the skin envelope, which can be used for immediate reconstruction. Nipple-sparing mastectomy also preserves the nipple and areola when oncologically appropriate; cited studies report local recurrence rates similar to skin-sparing mastectomy, with most recurrences not directly involving the nipple-areola complex. Reconstruction may use implants or your own tissue, and the choice depends on radiotherapy, breast size and shape, available donor tissue and recovery considerations. If radiotherapy is anticipated, reconstruction may be delayed until treatment is completed. Preserving skin or nipple can improve appearance, but suitability depends on cancer factors and healing. Nipple preservation is not suitable for every patient and requires careful oncologic selection.

Autologous reconstruction uses your own tissue, so donor-site problems are an inherent trade-off: you accept some donor-site limitation for the benefit of using your own tissue. In abdominal flaps, weakness, bulge, hernia or wound-healing problems may occur. Muscle-sparing approaches reduce these risks compared with earlier methods, but variable muscle dissection can still weaken the abdominal wall. Reported abdominal hernia rates after DIEP reconstruction vary, generally 0.7 to 4.9 percent. Physical therapy may help regain strength and adjust to limitations. Implant-based reconstruction avoids donor-site morbidity but has its own complications; autologous tissue can feel more natural. Risk depends on flap type, blood-vessel anatomy, prior surgery, tissue availability, obesity, overall health status and individual anatomy.

A reconstructed breast is not expected to exactly match the original. With tissue transfer, the moved tissue adapts to surrounding chest tissue and may change shape, size or position, so secondary refinement is frequently needed. If the nipple-areola complex was removed, that reconstruction is usually done later. Symmetry is a major goal, and many patients need remodeling of the opposite breast, sometimes in the first stage and sometimes later. Implant reconstruction may also need a second stage, such as replacing a temporary skin-stretching device with a permanent implant. The exact plan depends on radiotherapy, available tissue, breast size and your goals. This is common and does not mean the first surgery failed.
