“…The essential finding that round and anatomical implants have neither significant effect on the topography of single breast quadrants, nor on the entire topography of the breast, is concordant with findings in previous studies on the subjective perception of these effects [ 7 , 8 , 9 , 19 , 25 ]. The volumetric impact of all breast implants was mainly in quadrant II, followed by I, III, and IV.…”

“…These recordings support the surgeons in their planning and decision-making [ 1 , 2 , 3 , 4 , 5 , 6 ]. The choice of the appropriate implant has been discussed in several studies as one of the most important factors affecting the postoperative appearance of the breasts after augmentation [ 7 , 8 , 9 ]. Due to the lack of comparison between different implant shapes and volumes in the same patient [ 7 , 8 ] and the limited use of accurate measurements [ 9 ] obtained from photography, which can only reproduce the topography of the breast to a limited extent, data are not sufficient to enable an evidence-based choice of the most suitable implant.…”

Background: 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. Methods: 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 n = 130 single breast scans. These scans were analyzed for topographic shift quantification, nipple migration, and inter-landmark distances of the breast. Results: Implant size, but not implant shape leads to significant topographic shifts of the breast (p < 0.001 and p = 0.900, respectively). Both round and anatomical implants lead to a significantly higher volumetric increase in the upper quadrants compared to the lower quadrants (p < 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. Conclusions: 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.

“…In another effort to overcome some of the other morphological differences, implant choice might play a more defining role in trans women. Although discussions on the aesthetic outcomes and distinguishability of implant shapes in cis women have been long and ongoing, a recent anthropometric study showed that round and anatomically shaped implants influence breast morphology differently [7,17,24,26]. A cadaver study showed that anatomically shaped implants were more adept at creating a longer IMF-N, and to a lesser extent, lengthening the SN-N too [14].…”

Background The morphometric results after breast augmentations are generally understood to be clinically different between trans(gender) and cis(gender) women. The objective of this study was to establish these morphometric differences between the augmented breasts of trans and cis women and their implications for preoperative planning and expectation management of trans women. Methods A single-center, observational cross-sectional study was conducted. Three-dimensional images (VECTRA) of the chest were taken and used to measure preset morphometric parameters. Subsequently, several proportional morphometric outcome variables were calculated. We compared body, breast, and nipple dimensions and their interdependence between trans and cis women. The main outcome sets were (1) the relative dimensions of the chest, (2) the position of the breasts relative to the chest, (3) and the position of the nipple relative to the breast and nipple size. Results A total of 22 transgender and 22 cisgender women were included. The results showed that the breasts of the trans women were positioned more cranial. Furthermore, the nipple-areola complexes (NAC) were significantly smaller and positioned relatively more latero-cranial on the breasts. Conclusions Morphological characteristics of augmented breasts differ significantly between trans and cis women. The results of this study identified distinct differences between the augmented breasts of trans and cis women. Because of the apparent differences in results, surgical considerations, expectation management, and shared decision-making should play an even more pronounced role in breast augmentations in trans women. Level of evidence: Level III, risk/prognostic study.

“…(3D) surface body measurement have offered new possibilities to numerically assess the female breast [1,2,[6][7][8][9][10][11][12][13][14][15][16]. These technologies are characterized by significantly faster data acquisition compared with linear and circumference measurements, water displacement and other conventional methods [11,14].…”

Purpose To assess precise topographic changes of the breast, objective documentation and evaluation of pre- and postoperative results are crucial. New technologies for mapping the body using digital, three-dimensional surface measurements have offered novel ways to numerically assess the female breast. Due to the lack of clear demarcation points of the breast contour, the selection of landmarks on the breast is highly dependent on the examiner, and, therefore, is prone to error when conducting before-after comparisons of the same breast. This study describes an alternative to volumetric measurements, focusing on topographic changes of the female breast, based on three-dimensional scans. Method The study was designed as an interventional prospective study of 10 female volunteers who had planned on having aesthetic breast augmentation with anatomical, textured implants. Three dimensional scans of the breasts were performed intraoperatively, first without and then with breast implants. The topographic change was determined as the mean distance between two three-dimensional layers before and after augmentation. This mean distance is defined as the Topographic Shift. Results The mean implant volume was 283 cc (SD = 68.6 cc, range = 210–395 cc). The mean Topographic Shift was 7.4 mm (SD = 1.9 mm, range = 4.8–10.7 mm). The mean Topographic Shifts per quadrant were: I: 8.0 mm (SD = 3.3 mm); II: 9.2 mm (SD = 3.1 mm); III: 6.9 mm (SD = 3.5 mm); IV: 1.9 mm (SD = 4.3 mm). Conclusion The Topographic Shift, describing the mean distance between two three-dimensional layers (for example before and after a volume changing therapy), is a new approach that can be used for assessing topographic changes of a body area. It was found that anatomical, textured breast implants cause a topographic change, particularly on the upper breast, in quadrant II, the décolleté.
