Breast augmentation is the most performed cosmetic surgery in the world. Although smooth round implants are widely used, the trend in breast morphology change after dual-plane augmentation with such implants remains unclear. In this study, we analyzed the issue with the support of 3D scanning technology, which may help provide an objective basis for the evaluation of postoperative outcomes and the determination of follow-up time points.
Patients undergoing dual-plane augmentation with smooth round implants were prospectively included in this study. The variation trend of postoperative breast morphology was analyzed by measuring the specified linear distance, body surface distance, breast projection, nipple position and breast volume at different follow-up time points (1st month, post-1M; 3rd month, post-3M; 6th month, post-6M; 12th month, post-12M).
A total of 18 patients were included in this study. During the postoperative follow-up period, breast height prolonged while interval of the medial border gradually widened. Breast width was maintained without significant alterations from post-1M. The N-MBB lengthened with shortening of the N-LBB, meanwhile the N-IMF was prolonged by 0.6 cm. Breast volume was gradually reduced with the decrease in breast projection. The position of the nipple gradually shifted laterally, superiorly, and posteriorly after surgery. There was no statistically significant difference between the linear distance at post-3M and post-12M, while the surface distance, breast projection, nipple position and breast volume tended to be stable at post-6M.
After dual-plane augmentation with smooth round implants, the base contour of the breast shifted outwards and downwards, and stabilized after 3 months. The remaining breast morphological parameters reached a relative steady state by post-6M, which could be regarded as the time point for objective evaluation of postoperative effect.

隆胸术是全世界施行最多的美容手术。尽管圆形光滑假体被广泛应用，但双平面隆乳术后此类假体导致的乳房形态变化趋势仍不明确。本研究应用三维扫描技术对此问题进行分析，以期为术后效果评估和随访时间点的确定提供客观依据。
前瞻性纳入行双平面隆乳术且使用圆形光滑假体的患者。通过测量指定线性距离、体表距离、乳房突度、乳头位置和乳房体积，在术后不同随访时间点（1 个月，术后 1M；3 个月，术后 3M；6 个月，术后 6M；12 个月，术后 12M）分析术后乳房形态的变化趋势。
本研究共纳入 18 例患者。术后随访期间，乳房高度延长，内侧缘间距逐渐增宽。乳房宽度在术后 1M 时保持不变，之后无明显变化。N-MBB 延长，N-LBB 缩短，同时 N-IMF 延长 0.6cm。乳房体积随乳房突度下降而逐渐减少。术后乳头位置逐渐向外侧、上方和后方移位。术后 3M 和 12M 的线性距离无统计学差异，而体表距离、乳房突度、乳头位置和乳房体积在术后 6M 时趋于稳定。
圆形光滑假体双平面隆乳后，乳房基底部轮廓向外、向下移位，术后 3 个月基本稳定。术后 6 个月时，其余乳房形态参数达到相对稳定状态，可作为术后效果客观评价的时间点。
