Three-dimensional scanning offers new opportunities to enable objective and quantitative analysis of the breast. The authors introduce an innovative method of performing a thorough analysis of breast asymmetry by means of three-dimensional scanning.
One hundred breast augmentation patients underwent preoperative three-dimensional scanning. The coordinate system was established and the three-dimensional breast model was analyzed using software. The discrepancies of nipple level, nipple to midline distance, inferior mammary fold level, breast width, breast projection, breast volume, and anterior chest wall projection were measured.
The mean discrepancies of nipple level, nipple to midline distance, inferior mammary fold level, breast width, breast projection, and anterior chest wall projection were 4.9±3.7, 4.1±3.5, 4.7±3.5, 4.6±2.7, 5.4±4.1, and 4.4±2.9 mm, respectively. The mean discrepancy of breast volume was 48±42 ml. The incidence of significant asymmetry of nipple position was 72 percent. The incidence of significant asymmetry of the breast mound was 94 percent (patients with at least one parameter with significant asymmetry), and the incidence of asymmetric inferior mammary fold level, breast width, breast projection, and breast volume was 44, 46, 46, and 76 percent, respectively. The incidence of significant asymmetry of the anterior chest wall projection was 36 percent. None of the patients was completely free of asymmetry. Ninety-two percent had at least two parameters of asymmetry and 72 percent had at least three parameters of asymmetry.
A thorough evaluation of breast asymmetry can be carried out with the authors' innovative method. This study indicates that three-dimensional measurement of the breast will probably play an important role in implant selection to correct breast asymmetry.
三维扫描为实现乳房的客观定量分析提供了新的机会。作者介绍了一种通过三维扫描对乳房不对称进行全面分析的创新方法。
100 例乳房隆乳患者接受术前三维扫描。建立坐标系，使用软件对三维乳房模型进行分析。测量乳头水平、乳头到中线距离、下乳腺褶皱水平、乳房宽度、乳房突出度、乳房体积和前胸壁突出度的差异。
乳头水平、乳头到中线距离、下乳腺褶皱水平、乳房宽度、乳房突出度和前胸壁突出度的平均差异分别为 4.9±3.7、4.1±3.5、4.7±3.5、4.6±2.7、5.4±4.1 和 4.4±2.9mm。乳房体积的平均差异为 48±42ml。乳头位置显著不对称的发生率为 72%。乳房丘部显著不对称的发生率为 94%（至少有一个参数存在显著不对称的患者），下乳腺褶皱水平、乳房宽度、乳房突出度和乳房体积不对称的发生率分别为 44%、46%、46%和 76%。前胸壁突出度显著不对称的发生率为 36%。没有患者完全没有不对称。92%的患者至少有两个参数不对称，72%的患者至少有三个参数不对称。
作者的创新方法可以对乳房不对称进行全面评估。本研究表明，三维乳房测量可能在选择植入物以纠正乳房不对称方面发挥重要作用。
