Oncoplastic surgery combining partial mastectomy and immediate volume replacement using a thoracodorsal adipofascial cutaneous flap with a crescent-shaped dermis

Purpose The treatment of early breast cancer using breast-conserving therapy commonly ensures local control and acceptable cosmetic results. We herein report a useful technique, including the use of a thoracodorsal adipofascial cutaneous flap for reconstructing defects in the outer quadrant area after partial mastectomy, which achieved excellent results. Methods We performed partial mastectomy followed by immediate volume replacement using a modified thoracodorsal adipofascial cutaneous flap with a crescent-shaped dermis in ten patients. Results The modified oncoplastic technique was performed without any complications in all patients. Sufficient blood flow to the cutaneous flap with the crescent-shaped dermis was visualized in two patients during the operation after the injection of indocyanine green. The oncological and cosmetic results were excellent to good in these patients. Conclusions Oncoplastic surgery using a modified thoracodorsal adipofascial flap with a crescent-shaped dermis was successfully performed in patients with early cancer lesions in the outer quadrant, and the cosmetic results obtained were excellent.
