a b s t r a c tObjectives: To date, little is known about postoperative changes in breast volume after autologous breast reconstruction. The purpose of this retrospective study was to investigate breast volume changes following autologous free flap reconstruction and the factors affecting flap volume. Materials and methods: Patients who underwent deep inferior epigastric perforator, superficial inferior epigastric artery and profunda artery perforator flaps between December 2016 and January 2019 were included. Exclusion criteria were breast complications requiring surgical debridement, and the absence of at least two suitable three-dimensional images postoperatively. Three-dimensional stereophotogrammetry volume measurements were performed at the time of standard surgical check-ups. Changes in breast volume were modeled using a quartic polynomial curve function in a nested mixed effects model. Results: 136 breasts in 101 patients were included. An average decrease of predicted breast volume was found from 637.8 cc (95%-CI [624.4, 651.1]) at two weeks to 566.6 cc (95%-CI [535.1, 598.0]) after three and 567.6 cc (95%-CI [515.9, 617.6]) after six months postoperatively. Reconstruction timing and first postoperatively measured breast volume showed a statistically significant difference in initial reconstructed breast volume and in the shape of the relationship between time and breast volume, whereas autologous technique and BMI only showed a statistically significant difference in initial reconstructed volume and mastectomy indication in the shape of the relationship. Conclusion: The final overall flap volume decreased to 88.9% of its original volume after six months. Gaining more insight into the factors influencing flap volume is of crucial importance to facilitate predictable surgical outcomes.

“…As the automatic detection of the reference points by the Vectra ® software did not work as well as expected, the reference points were marked on the patient before the images were taken and then set manually accordingly in the software. This seems to be a common problem which is as well described by other researchers [19]. Following Eder et al [29], we used the positive effects of pre-marking the reference points [29].…”

“…The 3D breast volumetry was performed with the portable Vectra ® H2 (Can eld Scienti c, USA), which is frequently used in the literature [18][19][20][21][22][23][24][25][26]. The 3D model can be analysed in terms of breast volumes and various breast dimensions by using the BREASTsculptor ® software, which is integrated into the programme.…”

Purpose: Congenital breast asymmetry is a serious gynaecological malformation for affected patients. The phenotyping hits young women in puberty and is associated with a socio-aesthetic handicap, depression and psychosexual problems. Therefore, the time of therapy is usually early in view of the patient's entire life so that a sustainable solution is important. Although, postoperative outcome has been evaluated in several studies before, this study firstly analyses which objective parameters have the most influence on subjective satisfaction with long-term results.Methods: 34 patients with a diagnosed congenital breast asymmetry that underwent either lipofilling or implant therapy in the years of 2008 - 2019 were examined. On average, our collective was seven years postoperatively. Data was mainly gathered by manual measurements, patient-reported outcome measures (Breast Q™) and breast volumetry based on 3D scans (Vectra® H2, Canfield Scientific).Results: Among all analysed parameters, only the areola diameter correlated significantly negative with the subjective outcome satisfaction of the patient. Regarding the subjective assessment of the postoperative satisfaction with similarity of the breasts, again the mean of areola diameter, the difference of areola diameter between right and left breast and the difference of volume assessed with 3D scans correlated significantly negative.Conclusion: The areola diameter was shown to be a significant influencing factor for patient-subjective long-term satisfaction in breast asymmetry patients. Besides, 3D volumetry was shown to be a good tool for objectifying patient subjective assessments. Our findings could lead to further improvement of surgical planning and will be built upon in further studies.

“…It comes with Vectra ® Breast-Sculptor TM (Canfield Scientific,USA) software for point cloud processing and mesh generation. Using this software, the 3D model can be analysed in terms of breast volume and various breast dimensions as demonstrated in several studies [14][15][16][17][18][19][20][21][22]. Therefore, thirteen points were marked at the patient and subsequently picked in Breast-Sculptor TM , see Figure 2.…”

Congenital breast asymmetry represents a particular challenge to the classical techniques of plastic surgery due to a young group of patients. This study compares traditional breast augmentation using silicone implants to the more innovative lipograft technique regarding long-term results. To achieve this, we not only captured subjective parameters like satisfaction with outcome and symmetry, but also objective parameters such as breast volume and anthropometric measurements. Objective examination was performed manually and by using the Vectra® H2 photogrammetry scanning system. Patients who underwent implant augmentation and lipograft both showed no significant differences in patient´s satisfaction with surgical outcome (p = 0.55) and symmetry (p = 0.69). Furthermore, a breast symmetry of 93 % in both groups was reported. Likewise, no statistically significant volume difference between left and right breast was observed in both groups (p<0.41). However, on average, lipograft patients needed 1.3 procedures more until the desired result was achieved. In contrast, patients treated with implant-based breast augmentation usually need several implant changes during their life. In conclusion, both methods should be considered for patients with congenital breast asymmetry.
