Abstract

The distance between the mid-clavicle and nipple (MCN) is crucial in planning reduction mammoplasties. MCN has been shown to be superior in achieving nipple-areola complex symmetry. However, there is great variability in clavicle anatomy. Detecting clavicle asymmetries is crucial for achieving optimal postoperative breast symmetry. This study assessed clavicle asymmetries in patients undergoing reduction mammoplasties and used correlation analyses to understand the outcome measures, including variations in resection weight and clavicle angles. We included 100 patients who underwent reduction mammoplasties with wise-pattern skin resections. Clavicle height asymmetries were identified through preoperative anthropometric measurements. Clavicle angles were assessed from pre- and postoperative images to differentiate between fixed and dynamic asymmetries. Statistical analyses used frequency distributions, generalized linear models, and logistic regression. Clavicle height differences were identified in 78% of the patients using preoperative anthropometric measurements. Pre- and postoperative images revealed fixed clavicle angle differences in 45% of the cases and dynamic differences in 16%. Dynamic clavicle height asymmetries were significantly associated with differences in resection weight between the breasts (p = 0.012), smaller differences
