Abstract
The volume retention of breast autologous fat grafting is unpredictable, and the volume retention rate and related influencing factors have not been systematically reviewed. Therefore, this systematic review and meta-analysis aimed at evaluating the volume retention rate and related influencing factors of breast autologous fat grafting, which is for reconstructive or esthetic purposes. Literature search was conducted using the PubMed, Embase, Cochrane Library, and Web of Science databases from inception of study to December 2022. Sensitivity analysis was performed for all outcomes. Begg's test was performed to test publication bias. Subgroup analysis was performed based on population, method of fat preparation, method of volume measurement, number of fat grafting, and injected fat grafting volume. A total of 25 studies were included in this systematic review and meta-analysis. The follow-up time ranged from 3 to 36 months. Results showed that the pooled volume retention rate at the latest follow-up point was 54% [95% confidence interval (CI): 48.5%-59.5%]. Based on the fat preparation methods, the pooled rate was 51.5% (95%CI: 41.5%-61.5%) for centrifugation, which was higher than that for sedimentation [38.7% (95%CI: 30.9%-46.5%)]. In addition, the enrichment of stromal vascular fraction obtained after centrifugation was found to be associated with higher volume retention rate (weighted mean difference: 17.36, 95%CI: 8.84-25.87). Our findings may provide guidance for evaluating the volume retention rate of breast autologous fat grafting in clinical settings. Further studies are needed to verify our findings.

Abstract
BACKGROUND The authors propose a hybrid breast augmentation (HBA) method combining implants and fat grafting and explore the outcome and safety through a retrospective, single-center, propensity score-matched, comparative study. METHODS Outcome, satisfaction, and complications were compared between the HBA group (302 cases) and the implant-based breast augmentation (IBA) group (353 cases), and between the HBA group and the autologous fat grafting (AFG) group (277 cases). RESULTS The mean follow-up period was 31.7 months. After propensity score matching (PSM), 270 cases were matched between the HBA and IBA groups, and 156 cases were matched between the HBA and AFG groups. Compared with the IBA group, HBA achieved higher scores of implant visibility/palpability and upper pole contour with the specialists' evaluations (before and after PSM; P < 0.05). Regarding patient satisfaction, the scores of softness (before and after PSM), smoothness of the upper pole (before PSM), and overall satisfaction (after PSM) of the HBA group were better ( P < 0.05). Implant-related complications occurred at a similar rate. Compared with the AFG group, HBA achieved higher scores of shape (before and after PSM) and symmetry (after PSM) with evaluations by specialists ( P < 0.05). The scores of shape, symmetry, and overall satisfaction in the HBA group were better (before and after PSM; P < 0.05). The HBA group showed a lower incidence of palpable cysts, fat necrosis, oil cysts, and fat calcification (before PSM; P < 0.05). CONCLUSION When the three techniques were compared objectively, HBA presented better indices of aesthetic outcomes, satisfaction, and acceptable complications rates when compared with IBA and AFG.

Abstract
BACKGROUND Silicone implants have gone through adaptations to improve esthetic outcomes. With the progress of technology, including gel rheology, different properties have been introduced. Ergonomic style implants (ESI) feature enhanced rheological properties and provide a shaped contour with a round base. OBJECTIVES This study investigated outcomes for ESI in breast augmentation concerning lower pole stretching (LPS) and implant stability and describes an algorithm to assist in decision-making. METHODS A total of 148 patients (296 breasts) underwent breast augmentation with ESI; this procedure was indicated in patients with good skin quality and <6 cm between the nipple-areola complex and the inframammary fold. RESULTS The mean patient age was 29.6 years (range: 19-39), and 93 patients (62.8%) underwent primary breast augmentation with demi/full projection (average volume of 245 cc [175-375 cc]). Axillary incision and subfascial pocket were indicated in 115 (77.7%) and 72 (48%) cases, respectively. Average LPS values were 32.2% (24.91 mm) and 10.86% (9.42 mm) at up to 10 days and 10 days to 12 months postprocedure, respectively. Patients were followed for a mean of 29.9 ± 26.4 months (range: 6-66). Complication rates per breast and per patient were 5% and 10%, respectively, and included subcutaneous banding in the axilla (1.6%), implant displacement (1.2%), and wound dehiscence (0.8%). No cases of infection, seroma, or rippling complications were observed. CONCLUSIONS The present decision-making algorithm summarizes the process involved in breast augmentation using ESI and is intended to help standardize decisions. With correct planning, long-lasting outcomes can be achieved due to favorable interactions between ESI and the patient's tissues.

Abstract
SUMMARY Reoperative procedures after breast augmentation are frequently more complex than primary cases because of local complications and insufficient soft-tissue coverage. Although the transaxillary incision is often indicated in primary breast augmentation, limitations of this approach include secondary surgery and correcting complications after using this approach via the same incision. Combining the transaxillary technique with a subfascial pocket has been suggested to avoid breast scarring and the limitations of submuscular pockets represented by breast animation. With advances in autogenous fat grafting (AFG) techniques, implant coverage alternatives and more natural outcomes have been reported from more superficial implant pockets. Simultaneous AFG with silicone implants (defined as hybrid breast augmentation) has been evaluated recently as an attractive procedure. These two techniques combine to provide breast projection and natural cleavage while camouflaging implant edges. AFG is also important to reduce the intermammary distance and achieve a smoother transition between the breasts. The transaxillary approach can be useful in reoperative breast augmentation and avoids additional scarring on the breast. This article and the accompanying videos provide a detailed, step-by-step guide to reoperative hybrid breast augmentation using a subfascial transaxillary approach, with a predictable and optimized surgical outcome.

Abstract
BACKGROUND Hybrid breast reconstruction (HBR) combines silicone implants with fat grafting to improve implant coverage, treating local tissue deficiencies and leading to a more natural breast appearance. Recent data also indicated less capsular contracture after HBR. The authors developed a novel technique and animal model of cell-assisted (CA) HBR to illuminate its effects on capsular contracture. METHODS Animals received silicone implants in a dorsal submuscular pocket. Although animals of the HBR group received fat grafting around the implant without stem cell enrichment, rats of the CA-HBR1 and the CA-HBR2 groups received stem cell-enriched fat grafting with 2 × 10 6 and 4 × 10 6 adipose-derived stem cells immediately after implant insertion. On day 60, animals underwent sonography and elastography imaging and were euthanized, and outcome analysis was performed by means of histology, immunohistochemistry, chemical collagen quantification, and gene expression analysis. RESULTS With this novel technique, long-term survival of adipose-derived stem cells within the implant pocket was demonstrated after 60 days after implant insertion. CA-HBR led to significantly reduced thickness and collagen density of capsular contractures. In addition, CA-HBR resulted in reduced fibrotic responses with less occurrence of collagen type I and transforming growth factor-β in capsule tissue. Moreover, the addition of stem cells suppressed fibrotic and inflammatory responses on a genetic level with significant underexpression of collagen type I and transforming growth factor-β1. CONCLUSIONS With this new technique and animal model, the authors observed a preventive effect on capsular contracture substantiating the basis of clinical outcomes of HBR. The authors propose that the addition of stem cells to HBR might booster its beneficial results. CLINICAL RELEVANCE STATEMENT Stem cell-enriched fat grafting around silicone implants may reduce the risk for capsular contracture after silicone breast implantation. While fat grafting alone already shows beneficial effects, the addition of stem cells to the fat graft can potentiate this effect.

Complication Rates after Breast Surgery with the Motiva Smooth Silk Surface Silicone Gel Implants-A Systematic Review and Meta-Analysis. J Clin Med 2023; 12:jcm12051881. [PMID: 36902667 PMCID: PMC10004118 DOI: 10.3390/jcm12051881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 02/13/2023] [Accepted: 02/23/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND In an era where textured devices are being phased out due to concerns about BIA-ALCL, the Motiva SilkSurface breast implants intend to alleviate historical prosthesis-related complications. However, its safety and feasibility remain unelucidated. METHODS An analysis of Pubmed, Web of Science, Ovid, and Embase databases was performed. A total of 114 studies were identified initially, and 13 of these met the inclusion criteria and were assessed regarding postoperative parameters such as complication rate or follow-up period. RESULTS In 4784 patients who underwent breast augmentation with Motiva SilkSurface breast implants, a total of 250 (5.2%) complications were observed. Short- and medium-term complication rates ranged from 2.8-14.4% and 0.32-16.67%, respectively. The most common complication was early seroma (n = 52, overall incidence = 1.08%), followed by early hematoma (n = 28, overall incidence = 0.54%). The incidence of capsule contracture was 0.54% and breast implant-associated-anaplastic large cell lymphoma was not observed. DISCUSSION Although the majority of the studies in the current literature suggest the distinction of the Motiva SilkSurface breast implants in terms of postoperative complications and capsular contracture, its safety and feasibility need to be further elucidated with well-designed, large-scale, multicenter, prospective case-control studies. Other: No funding was received.

Abstract
BACKGROUND The emerging concerns around breast implant-associated anaplastic large cell lymphoma and other chronic inflammatory-related conditions have instigated a wider use of smooth devices. OBJECTIVES The authors aimed to present 6-year data following the introduction of Motiva implants (Establishment Labs Holdings Inc.; Alajuela, Costa Rica) into their previously texture-dominated practice. Additionally, the authors aimed to provide technical recommendations on how to efficiently incorporate these devices into surgical practice and minimize the learning curve. METHODS Data of 1053 primary and secondary breast augmentations conducted between April 2015 and December 2020 in 2 centers (Victoriakliniken in Sweden and the European Institute of Plastic Surgery in Cyprus) were retrospectively evaluated to obtain data on chosen implant characteristics and complications that led to reoperation, prior to and following modifications to surgical practice in 2018. RESULTS The data from 6 consecutive years demonstrate a low device-related complication rate with Motiva implants. In 2018, following adaptions in surgical practice, the complication rate significantly declined. CONCLUSIONS Motiva implants demonstrate a low complication rate and safety profile for women undergoing primary and secondary breast augmentation procedures. However, to reap the benefits of the antifibrotic profile, technical adaptions and optimal patient planning based on the patient and device characteristics are instrumental. Employing the key principles laid out in this study provides a means for delivering both clinically safe options to patients with aesthetically pleasing long-term results. LEVEL OF EVIDENCE: 4

Abstract
INTRODUCTION There is widespread recognition of the importance of assessment of patient satisfaction and well-being after breast reconstruction. However, few studies of fat grafting performed simultaneously with implant-based breast reconstruction (IBBR) have accounted for confounding factors, such as patient background and information bias. The aim of this study was to examine patient satisfaction and well-being using multivariate analysis of BREAST-Q scores in patients treated with IBBR combined with fat grafting. METHODS Seventy-one consecutive patients who underwent IBBR with silicone breast implants were enrolled for a prospective cohort study. Among these patients, 56 responded to the BREAST-Q questionnaire, including 24 who underwent fat grafting at the same time as IBBR (FAT+ group) and 32 who underwent IBBR alone (FAT- group). The BREAST-Q questionnaire was completed 1 year after surgery. Statistical analysis was performed using descriptive and summary statistics to identify differences between the 2 groups. RESULTS Logistic regression analysis showed that the FAT+ group was significantly more likely than the FAT- group to have satisfaction with breasts (P = 0.0201) and satisfaction with outcome (P = 0.0364). CONCLUSIONS Multivariate analysis with consideration of confounding factors indicated that addition of fat grafting to IBBR improves outcomes of breast reconstruction. These results suggest that a minor surgical procedure of fat grafting can improve patient satisfaction and outcomes after breast reconstruction.

Abstract
BACKGROUND The main challenge with fat grafting is loss of some of the graft to postsurgery resorption. Previous studies suggest that adipose-derived stromal cells (ASCs) can improve the volume retention of fat grafts but there is a lack of randomized trials to support the use of ASCs in clinical practice. OBJECTIVES This trial aimed to investigate whether ASCs improve fat graft volume retention in patients undergoing breast augmentation with lipofilling. METHODS This was a double-blind, randomized controlled trial of breast augmentation with ASC-enriched fat grafting. Healthy women aged 30 to 45 years were enrolled. First, the participants underwent liposuction to obtain fat for culture expansion of ASCs. Then, the participants were randomly assigned to undergo a 300- to 350-mL breast augmentation with ASC-enriched fat grafting (10 × 106 ASCs/mL fat graft) to 1 of their breasts and placebo-enriched fat grafting of identical volume to the contralateral breast. The primary outcome was fat graft volume retention after a 1-year follow-up measured with MRI. The trial is registered at www.clinicaltrialsregister.eu (EudraCT-2014-000510-59). RESULTS Ten participants were included in the trial; all completed the treatment and follow-up. No serious adverse events occurred. Fat graft volume retention after 1 year was 54.0% (95% CI, 30.4%-77.6%) in the breasts treated with ASC-enriched fat grafting (n = 10) and 55.9% (95% CI, 28.9%-82.9%) in the contralateral breasts treated with placebo-enriched fat grafting (n = 10) (P = 0.566). CONCLUSIONS The findings of this trial do not support that ASC-enriched fat grafting is superior to standard fat grafting for breast augmentation. LEVEL OF EVIDENCE: 2

Abstract
Background Autologous fat transfer is common in breast augmentationor reconstruction. However, AFG recipient site in the breast for fat grafting has not been carefully investigated. Methods Forty female patients requiring breast augmentation with fat grafting were randomly assigned into two groups. The retromammary group received 2/3 fat into the retromammary space and the other 1/3 into the subcutaneous and retropectoral planes. The retropectoral group received 2/3 fat into the retropectoral plane and the other 1/3 into the subcutaneous and retromammary planes. The fat grafting result at 6 months was assessed by 3D laser surface scanning and then ultrasound. Any complications were recorded during follow-up. Samples from a patient who underwent fat grafting for 6 months was obtained and histological examination was conducted. Results No significant difference in the retention rate after 6 months was observed between the two groups (retromammary group: 35.9% ± 6.6; retropectoral group: 39.3% ± 5.1, p = 0.1076). The retromammary grouphad a higher incidence of oil cyst formation than the retropectoral group. Histological examination showed that there were more oil cysts and mac2 positive macrophage infiltration in the fat cells in retromammary group, while retropectoral group had more small-size adipocytes. Conclusion Although fat grafting into the retropectoral plane did not provide a superior fat graft retention rate, it did lower the incidence of complications. The retropectoral space show great potential to become a favorable recipient site.

Abstract
BACKGROUND Reoperative augmentation mammoplasty (RAM) is a challenging procedure, with the highest rates of complications and revision. Complications include implant malposition, lateral displacement, bottoming out, and rotation. These deformities can be addressed with various procedures, but the pocket control and stability of the new smooth implant surface may present limitations. OBJECTIVES This study revisits a previously described predictable approach in primary breast augmentation and defines a surgical treatment algorithm for RAM technique selection. METHODS Between 2017 and 2021, 72 patients (144 breasts) underwent RAM with composite reverse inferior muscle sling (CRIMS) technique and its technical variations (types I-IV). CRIMS technique involves placing a silicone gel implant into the submuscular (SM) pocket with an inferior sling of the pectoralis major muscle based on the dimensions of the implant, in combination with support points/dermal bridge sutures to stabilize the implant and glandular tissue at the lower breast pole (LBP). Reasons for surgery were ptosis (92%), implant and malposition (59.6%). Patients were followed for at least 6 months in 5 cases (6.9%), at least 12 months in 50 cases (69.4%), for at least 36 months in 10 cases (13.8%), and more than 36 months in 7 cases (9.7%) (mean 34 months; range 6-48 months). Patients were evaluated in terms of resolution of symptoms, satisfaction, and complications. Three-dimensional imaging (3DI) obtained from the Divina scanner system was used and followed up for 1 year to evaluate breast position, lower pole stretch (LPS), and intermammary distance (IMD). RESULTS Eleven cases of minor complications were observed in 9 patients (12.5%): hypertrophic scarring in 4 (5.5%), wound dehiscence in 4 (5.5%), Baker II/III capsular contracture in 1 (1.3%). SmoothSilk surface silicone implants were used in all cases, with an average volume decrease of 120 cc. Sixty-eight patients (94.4%) were either very satisfied/satisfied with their aesthetic result. Breast images were performed in a group of 65 patients (90.2%), and in 7 breasts (10.7%), localized oil cysts were observed. The value for LPS was 7.87% (p <0.0001) between 10 days and 1 year, with the majority occurring early in the first 3 months, indicating that the LBP/implant remains steady during the last months of follow-up. No cases of fat necrosis/seroma were observed. There were no signs of intra/extracapsular ruptures, capsular contracture. There were 2 cases (3%) of minimal implant displacement and no cases of rotation. CONCLUSIONS CRIMS and its variations can be performed successfully in RAM. An algorithmic approach can facilitate the pre- and intraoperative decision-making process and provide the new pocket control and implant stability with acceptable complication rates. Further accurate evaluation is recommended to understand the benefits or disadvantages of CRIMS compared to other RAM techniques.

Optimizing Surgical Outcomes with Small-Volume Silicone Implants Associated with Autogenous Fat Grafting in Primary and Revision Breast Augmentation Surgery: Soft Weight Hybrid (SWEH) Concept.

Abstract
BACKGROUND Simultaneous association of autologous fat grafting (AFG) with silicone implants, defined as a hybrid procedure, has been proposed for breast augmentation (BA). In some patients, larger-volume implants may result in larger incisions, with long-term effects including implant palpability, soft tissue atrophy, and secondary ptosis. Some patients do not want large volume implants, or have insufficient soft tissue coverage. Recent improvements in AFG have led to new surgical options in BA for addressing these cases. OBJECTIVES This study combines AFG in BA using small-volume implants, known as the SWEH (soft weight hybrid) approach, and evaluates aesthetic advantages and outcomes following primary/secondary BA. METHODS 25 patients (50 breasts) underwent SWEH procedures; this approach was indicated when the overlying tissue was insufficient to adequately cover the implant and patients refused large-volume implants. Three-dimensional images were obtained using a Divina 3D scanner system (AX3 Technologies, Miami, USA) to assess breast volume (BV) and intermammary distance (IMD) during follow-up. RESULTS Mean patient age was 29.3 years (range: 21-42) and mean body mass index was 19.3 kg/m2 (15.3-27.2). The most common implant (SmoothSilk surface Round/Ergonomix style) volume was 180 cc (175-215), and patients received a mean volume of 125 cc of fat (89-168)/breast in the subcutaneous tissue. Preoperative average BV measurements were 236.85 cc (170-335). At 3 and 12 months post-procedure, the average BV values were 488.82 and 478.73cc, respectively (p=0.475). The average preoperative IMD was 31.76 mm (range, 22-43); at 3 and 12 months post-procedure, the average IMD was 20.47 and 20.94 mm, respectively (p=0.61). Postoperative complications included subcutaneous banding in the axilla (n = 1; 4%) and hypertrophic scarring (n = 1; 4%). Breast imaging exams were performed; in 2 breasts (8%) localized oil cysts were observed; no cases of suspicious calcifications, fat necrosis, or lumps were seen. Fat retention rate (1 year) was calculated by the difference between the BV expected with 100% fat intake and the real BV observed. In our sample we observed an average of 72.7 (range: 69.2-77.3, SD: 2.63) and 76.7 (range: 72.3-79.9, SD: 2.18) percent of fat intake on the right and the left breast respectively. No rippling, implant malposition, or infection was observed during a mean follow-up of 22 months (6-40). CONCLUSIONS SWEH is a useful surgical alternative that combines the benefits of AFG and implant-based augmentation, particularly with regard to soft tissue coverage, and avoids the limitations of larger-volume implants. The association of small-volume gel implants and smaller scars can yield satisfactory aesthetic outcomes.

Abstract
Abstract
Background
Autologous fat transplantation for breast augmentation represents an increasingly interesting technique in plastic surgery. Only a few standardized procedures are available. Hybrid augmentation mastopexy combines the benefits of autologous fat transplantation and implant-based breast augmentation mastopexy, reducing implant-related complications and prothesis size. Herein, we describe our surgical approach as a “hybrid aesthetic surgery.”
Methods
A retrospective analysis of all patients who underwent hybrid breast augmentation and lifting with simultaneous fat grafting was carried out. Clinical outcomes, ultrasound evaluation of upper pole fullness, aesthetic postoperative results, and complications were examined.
Results
Eighteen patients with a mean age of 33 years (range: 24–52 years) and mean BMI of 25.8 kg/m2 (range: 21.4–32.1 kg/m2) were included in this study. Mean injected fat volume per breast was 115 cc (range: 78–144 cc). Patients were followed up for a mean of 9.4 months (range: 6–24 months). No fat necrosis or major complications were encountered during the follow-up. Patient satisfaction was high in terms of breast shape, size, and coverage of the breast implant. No recurrence of ptosis was observed yet and no secondary revision surgery was performed.
Conclusions
Hybrid mastopexy augmentation is an effective and safe procedure that combines the benefits of autologous fat grafting and implant-based breast augmentation. The transfer of autologous soft tissue allows obtaining a natural breast shape, reducing the onset of rippling and prothesis size. The reduction of prothesis size prevents ptosis recurrence but provides the desired projection. This reliable option improves long-term breast shape with elevated patient’s satisfaction.
Level of evidence: Level IV, therapeutic study.

Abstract
BACKGROUND Simultaneous application of the axillary approach (AA) with the subfascial pocket (SF) has been proposed for breast augmentation (BA) surgery. New silicone implant technology and recent improvements in autologous fat grafting (AFG) have ushered in a new era for BA. OBJECTIVES The aim of this study was to present the combined subfascial ergonomic axillary hybrid (SEAH) method and evaluate its aesthetic benefits after primary/secondary BA. METHODS In total, 42 patients (84 breasts) underwent BA with the SEAH technique; this approach was indicated when the overlying tissue was insufficient to adequately cover the implant. RESULTS Mean patient age was 34.6 years (range, 28-56 years), mean BMI was 18.8 kg/m2 (range, 14.4-26.1 kg/m2). The most common implant (Motiva SmoothSilk surface Ergonomix style) volume was 255 cc (range, 175-355 cc), patients received a mean fat volume of 96 mL (range, 60-145 mL) per breast in the subcutaneous tissue. The average lower pole stretch value was 40.5% (21.75 mm) and 13.1% (9.9 mm) for preoperative to 10 days postprocedure and 10 days to 18 months postprocedure, respectively. Postoperative complications included subcutaneous banding in the axilla (n = 3, 7.1%), small wound dehiscence (n = 1, 2.3%), and hypertrophic scarring (n = 1, 2.3%). No rippling, implant malposition, infection, or fat necrosis was observed during a mean follow-up of 18 months (range, 6-32 months). CONCLUSIONS SEAH is a useful and versatile technique combining the benefits of AFG and implant-based augmentation, particularly with regard to soft tissue coverage, and avoids the limitations of the submuscular position. The combination of ergonomic gel implants and a SF pocket can yield satisfactory aesthetic outcomes. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Breast augmentation with implants continues to be the most popular aesthetic surgical procedure performed worldwide. Fat grafting may improve the results of breast augmentation and breast reconstruction with implants. However, fat grafting to the breast with implants carries the risk of implant puncture. To our best knowledge this is the first case in which polyurethane implant puncture during fat grafting is described. CASE PRESENTATION We report multiple bilateral implant punctures with the cannula during fat grafting in a patient who previously underwent breast reconstruction with polyurethane implants. CONCLUSIONS Implants that promote tissue ingrowth may be more prone to puncture with the cannula during fat grafting. Specific planning and surgical maneuvers decrease the risk of implant puncture.
