New Insights Into Breast and Chest Wall Asymmetry in the Aesthetic Patient

Abstract

Abstract Background Asymmetry, a prevalent phenomenon throughout the human body, prompts this retrospective study, in which the authors aim at discerning potential patterns in its manifestation. Building upon our previous investigations in which left-sided chest wall and pelvic bone width surpassed their right-sided counterparts, a hypothesis is formulated suggesting the likelihood of the right breast being narrower and longer compared with the left. Objectives Our objective in this study is to investigate the correlation between the left-sidedness phenomenon in the chest wall and breast shape and appearance, with the aim of understanding its potential impact on outcomes in breast aesthetic surgery. Methods A random selection of pictures from 600 female patients undergoing various aesthetic breast procedures formed the basis of this study. Exclusion criteria involved the elimination of 254 pictures with nonstandard photography. Horizontal and vertical parameters of breasts and chest walls were measured, and the results on both sides were systematically compared to validate our hypothesis. Results On the left side, the chest wall, the distance between the nipple and the midline, and that of the nipple and the anterior axillary line were significantly wider. Vertical measurements, including the sternal notch to the nipple, the clavicle to the nipple, and the clavicle to inferior breast distance, although longer, did not exhibit statistical significance. Conclusions Approximately 77% of patients displayed wider breasts and chest walls on the left side. However, this observed asymmetry did not yield a statistically significant impact on the length of the breasts. Level of Evidence: 3 (Diagnostic)
