Abstract:
Objective To derive a formula for predicting intraoperative resection weights of reduction mammoplasty with double-circle periareolar incision.
Methods Data were collected from 78 consecutive patients receiving reduction mammoplasty with double-circle periareolar incision (133 sides) between 2003 and 2015, including preoperative bilateral clavicle-to-nipple distance, sternal notch-to-nipple distance, nipple-to-ipsilateral costoclavicular line distance, nipple-to-inframammary crease distance, nipple-to-anterior axillary line distance(cm), and resected weight (g) on each side of breast measured during the surgery. Multiple stepwise regression analysis was performed to establish the relationship between preoperative measurements and the resection weight.
Results Formulas were established as follows:resected weight=(32×clavicle-to-nipple distance+31×nipple-to-inframammary crease distance+8×nipple-to-ipsilateral costoclavicular line distance)-986, or resected weight=(25×sternal notch-to-nipple distance+32×nipple-to-inframammary crease distance+13×nipple-to-ipsilateral costoclavicular line distance)-868.
Conclusion This formula summarizes the experience of reduction mammoplasty with double-circle periareolar incision, which could guide the surgeon in preoperative estimation, intraoperative resection, and postoperative maintenance of breast symmetry.
