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.
Highlights
Augmentation mammaplasty has been one of the most commonly performed cosmetic surgical procedures
The patient satisfaction scale had a mean value of 8.860.9 at post-12M
In paired images of the post-1M and post-12M, we found the breast contour had a relatively full upper pole at post-1M and had a relatively full lower pole at post-12M (Figure 9)
Summary
Augmentation mammaplasty has been one of the most commonly performed cosmetic surgical procedures. Pectoral muscle coverage can reduce implant visibility and palpability and decrease risk of capsular contracture It sacrifices lower pole fullness and inframammary fold definition, with increased risk of lateral and superior implant displacement or malposition over time [1,3]. Dual-plane breast augmentation was introduced with more benefits than other pocket locations, but there are some concerns about the possible increasing risk of palpable or visible implant inferiorly [4,5,6]. To answer this question, evaluation of breast postoperative morphological changes is necessary. This study aims to track and analyze breast dynamic morphological changes after dual-plane breast augmentation with three-dimensional (3D) scanning technique
