A Prospective Study of Breast Dynamic Morphological Changes after Dual-plane Augmentation Mammaplasty with 3D Scanning Technique

Abstract

BackgroundThe dual-plane technique has been widely used in augmentation mammaplasty procedures. However, there are some concerns about aesthetic contour maintenance for long time after muscle releasing. This study aims to track and analyze breast dynamic morphological changes after dual-plane breast augmentation with three-dimensional (3D) scanning technique.MethodsThirteen dual-plane anatomic implant augmentation patients underwent 3D scanning preoperatively (pre-OP) and postoperatively in four time points (1 month: post-1M, 3 months: post-3M, 6 months: post-6M and 12 months: post-12M). The linear distance, breast projection, nipple position, breast volume and breast surface area were measured and analyzed on the 3D models over time.ResultsCompared with post-12M, no significant differences were found in distances of nipple to midline, nipple to inframammary fold and sternal notch to the level of inframammary fold after 6 months in both straight-line distance and its projection on surface. The distances between sternal notch and nipple had no significant difference after post-1M. Breast volume changes had no significant difference after post-3M. The volume and area percentage of upper pole decreased while the lower pole’s increased gradually. The surface showed no significant changes after post-1M. The changes of breast projection had no significance after post-1M either. The nipple moved 1.0±0.6 cm laterally(X axis), 0.6±0.7 cm upward(Y axis) and 2.3±1.1 cm anteriorly (Z axis) at post-12M, and the differences were not significant after post-1M.Conclusions3D scanning technique provides an objective and effective way to evaluate breast morphological changes after augmentation mammaplasty over time. Dual-plane augmentation optimizes breast shape especially in the lower pole and maintains stable aesthetic outcome during the 12 months follow-up. Most of the contour changes and the interadaptation with the implant have completed 6 months after operation. Therefore, 6 months could be chosen as a relatively stable observing period in the assessment of postoperative outcomes of dual-plane breast augmentation.

Asian Breast Augmentation

“…Summarized data from these studies are shown in Table 1 . Korea (7 series, 1380 cases) was the most represented nation, 12 , 15 , 17 , 19 – 22 followed by China (3 series, 622 cases), 14 , 16 , 23 Taiwan (1 series, 57 cases), 18 and Japan (1 series, 30 cases). 10 All studies were prospective and observational, and 3 offered comparative data.…”

Review of three-dimensional (3D) surface imaging for oncoplastic, reconstructive and aesthetic breast surgery

“…Breast volumes decreased from the first post-operative volume, and the final breast volume was reached between one and three months after surgery. A similar study was undertaken by Ji et al [93] using 3D-SI to investigate morphological changes after dual-plane augmentation mammoplasty. They found that sternal notchnipple distance was stable after one month, whereas nipple to IMF continued to increase until 6 months as volume redistributed from upper to lower pole.…”

Improved accuracy of breast volume calculation from 3D surface imaging data using statistical shape models

“…3D imaging has also been used to investigate postoperative courses. Eder et al showed that posoperative changes after breast reduction continue for 3-6 months [33], and after breast augmentation for 3 months [34], while another group suggested 6 months [35]. Others have focused on symmetry, finding a high grade of breast asymmetry in general population [36], and in 92 out of 100 patients after augmentation [37].…”
