Postoperative cosmesis of the reconstructed breast depends on the interrelation of shape, size (volume), and symmetry. In this study, reconstructed breasts were analyzed with 3-dimensional projections generated by laser light scanning. Fifty-one cases of breast reconstruction following mastectomy (16 cases of rectus abdominis flap, 15 cases of latissimus dorsi flap, and 20 cases of tissue expansion) were evaluated 6 months postoperatively. Shape, volume, and symmetry were quantitatively evaluated. Captured images of the normal breast were mirror-reversed and superimposed on images of the reconstructed breast. Differences in the generated Moire patterns were used to quantitatively compare breasts. The method was rapid, reproducible, and accurate in comparison to thermoplaster casts. It was found that rectus abdominis flaps applied following total mastectomy and latissimus dorsi flaps applied following partial mastectomy gave the best results for their relatively low degree of asymmetry. Application of tissue expansion led to greater asymmetry and poorer overall cosmesis. In conclusion, a 3-dimensional laser light scanning system makes it possible to quantitate the cosmetic outcome following breast reconstruction.
再造乳房的术后美容效果取决于形状、大小（体积）和对称性之间的相互关系。在本研究中，利用激光扫描生成的三维投影对再造乳房进行分析。对51例乳房切除术后乳房再造病例（腹直肌肌皮瓣16例、背阔肌肌皮瓣15例、组织扩张20例）术后6个月进行评估。对形状、体积和对称性进行定量评估。将采集的正常乳房图像进行镜像翻转后叠加在再造乳房图像上。利用生成的莫尔条纹图案差异对乳房进行定量比较。与石膏模型相比，该方法快速、可重复且准确。结果发现，全乳切除术后应用腹直肌肌皮瓣以及部分乳房切除术后应用背阔肌肌皮瓣，因其不对称程度相对较低，效果最佳。组织扩张的应用导致更大的不对称性和更差的整体美容效果。总之，三维激光扫描系统能够对乳房再造后的美容效果进行定量评估。
