Objective evaluation of breast asymmetry surgical treatment should consider not only breast shape but also breast volume.
For this study, 22 patients with primary breast asymmetry were evaluated by magnetic resonance imaging (MRI) as well as linear measurements preoperatively and 6 months postoperatively. The mean difference between the pre- and postoperative linear measurements was graduated from excellent to poor. Breast volume was estimated by MRI from axial reconstruction for three-dimensional application using the Cavalieri formula and specific software.
A strong correlation (r = 0.817) was found between the pre- and postoperative breast volumes, as increased or decreased by the surgical procedure. Patients with less postoperative volume differences tended to have the best ratings with linear measurements. When the same surgical procedure was performed bilaterally or when only one breast was treated by surgery, greater volume symmetry was observed.
Linear measurements and MRI are objective methods for evaluating postoperative symmetry, and when used in association, can help plastic surgeons to achieve favorable results in mammary asymmetry treatment.
对乳房不对称手术治疗的客观评估不仅应考虑乳房形状，还应考虑乳房体积。
在本研究中，对22例原发性乳房不对称患者在术前及术后6个月通过磁共振成像（MRI）以及线性测量进行评估。术前和术后线性测量的平均差异从优到差进行分级。使用卡瓦列里公式和特定软件，通过MRI从轴向重建进行三维应用来估计乳房体积。
手术导致的术前和术后乳房体积之间存在很强的相关性（r = 0.817）。术后体积差异较小的患者在线性测量中往往获得最佳评级。当双侧进行相同的手术操作或仅对一侧乳房进行手术时，观察到更大的体积对称性。
线性测量和MRI是评估术后对称性的客观方法，联合使用时可帮助整形外科医生在乳房不对称治疗中取得良好效果。
