BACKGROUND: Nowadays, more and more immediate breast reconstructions are carried out after cancer treatment. For performing radical mastectomy, there are several recognized techniques. In quadrantectomy, the options for defect repair range from primary closure to the use of oncoplastic surgery techniques. In the case of external quadrant tumors, there is no option of rotation of the entire latissimus dorsi muscle, which usually exceeds the actions necessary for repairing lost volume. A new option for post-quadrantectomy reconstruction in external quadrants is proposed in this study. METHODS: The surgical technique consists of dissection of the lateral segment of the latissimus dorsi muscle by an extension of the incision for lesion removal in the same supine position, followed by rotation and modeling of this segment to repair the defect caused by cancer removal. Twenty-one women aged 33 to 69 years underwent quadrantectomies of external quadrants followed by reconstruction with the technique described in this paper. To evaluate the method, each result had a score attributed to volume, shape, symmetry, and changes in the nipple areolar complex, as well as scar and operated quadrant surface. RESULTS: The obtained results of volume and shape were superior in relation to those of symmetry. The average grade was 7.048, equivalent to B concept. CONCLUSIONS: The new technique decreased surgical time. The acquisition of the B concept demonstrates the method's feasibility.
