Reconstruction of the breast conservation deformity.

The era of breast conserving treatment of early-stage breast carcinoma has created reconstructive challenges for the plastic surgeon. Although good to excellent cosmetic outcomes occur in the majority of patients, a significant number could benefit from additional reconstructive measures. Because of the need for continuing surveillance following breast-conserving therapy, estimated at 5–10% after fifteen years, plastic surgeons should choose techniques that do not interfere with the detection of recurrent breast carcinoma. Myocutaneous flaps-in particular, the latissimus dorsi and transverse rectus abdominis—have fulfilled the reconstructive needs of these patients by providing well-vascularized soft tissue. Postoperative radiological evaluation has demonstrated that these flaps are radiolucent, unlike breast implants that can obscure accurate mammographic interpretation. Myocutaneous flaps have been used for both immediate and delayed reconstruction of post-breast conservation deformities. The delayed approach offers the benefit of an established contour deformity that usually involves cutaneous, parenchymal, and nipple-areolar components. Moderate overcorrection of the defect has been advocated in anticipation of ongoing postradiation wound contraction and fibrosis. Immediate reconstruction of lumpectomy and partial mastectomy defects permits wider initial excision of the breast lesion, but can be compromised by positive histological margins. Long-term results suggest stability of the aesthetic outcome following reconstruction of delayed deformities.
