Thanks to 3D imaging, it is possible to measure the influence of different parameters on breast augmentation. In this study, we compare the effect of different shapes and sizes of breast implants on the topography of the resulting breast. Furthermore, the impact of different breast implants on inter-landmark distances and on changes of the nipple position was assessed.
This interventional prospective study was carried out on 10 female patients after collecting informed consent. 3D scans of the native and augmented breasts were performed intraoperatively with small, medium, and large sizes of both anatomical and round implants, resulting in a total of = 130 single breast scans. These scans were analyzed for topographic shift quantification, nipple migration, and inter-landmark distances of the breast.
Implant size, but not implant shape leads to significant topographic shifts of the breast ( < 0.001 and = 0.900, respectively). Both round and anatomical implants lead to a significantly higher volumetric increase in the upper quadrants compared to the lower quadrants ( < 0.001). Nipple migration into the superomedial quadrant was seen in about 90% of augmentations. No evident differences in inter-landmark distances were observed when round and anatomical implants of different sizes were compared.
Implant size rather than shape influences the postoperative aesthetic results. No significant difference in topographic shift was found comparing round and anatomical implants, suggesting that both implant shapes result in comparable aesthetic outcomes.
得益于三维成像技术，能够测量不同参数对隆胸手术的影响。在本研究中，我们比较了不同形状和尺寸的乳房植入物对术后乳房外形的影响。此外，还评估了不同乳房植入物对标志点间距离以及乳头位置变化的影响。
在获得10名女性患者的知情同意后开展了这项前瞻性干预研究。术中使用小号、中号和大号的解剖型及圆形植入物对患者的自然乳房和隆乳后的乳房进行三维扫描，共获得130次单乳房扫描数据。对这些扫描数据进行分析，以量化乳房的地形变化、乳头移位情况以及标志点间距离。
植入物大小而非形状会导致乳房出现显著的地形变化（分别为P<0.001和P = 0.900）。与下象限相比，圆形和解剖型植入物均使上象限的体积显著增加（P<0.001）。在约90%的隆胸手术中可见乳头向上内侧象限移位。比较不同尺寸的圆形和解剖型植入物时，未观察到标志点间距离有明显差异。
植入物大小而非形状会影响术后美学效果。比较圆形和解剖型植入物时，未发现地形变化有显著差异，这表明两种植入物形状产生的美学效果相当。
