Abstract
Lipofilling has emerged as an effective technique in breast reconstruction for enhancing aesthetic outcomes and addressing residual deformities. Traditionally, fat grafting has been performed as a secondary step in implant-based breast reconstruction during the replacement of the expander with a breast implant or as a revisional procedure. Our study investigates the technical feasibility and presents preliminary results of a new promising technique for delivering fat grafting in a three-dimensional (3D) shape, directly during mastectomy with immediate breast reconstruction or in delayed breast reconstructive procedures. Our new 3D lipogluing technique involves securing the fat tissue in a 3D manner using fibrin glue. This method enhances the coverage of soft tissues and provides improved volume and shape supplementation. In selected cases between December 2015 and September 2023, we treated 24 patients using the 3D lipogluing technique and five patients using 3D lipocubing (without use of fibrin glue).The patient cohort consisted of different indications for breast reconstructions: direct-to-implant, expander-based breast reconstruction, and "conservative" surgery. Preliminary findings suggest the technique is a safe and effective approach that can enhance the soft-tissue envelope of reconstructed breasts by acting as an autologous scaffold, owing to its regenerative properties. This technique not only improves the overall aesthetic outcome but also has the potential to reduce implant-related complications. Furthermore, ongoing studies are investigating methods to optimize the results and explore the potential application of 3D lipogluing and 3D lipocubing in breast-conserving oncoplastic surgery, cosmetic breast surgery, and other areas of plastic reconstructive and aesthetic surgery.

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
Due to refinements in operating techniques, autologous breast reconstruction has become part of standard care. It has become more difficult to advise patients due to the expansion of oncologic options for mastectomy, radiation therapy and the variety of reconstructive techniques. The goal of reconstruction is to achieve oncologically clear margins and a long-term aesthetically satisfactory result with a high quality of life. Immediate reconstruction preserves the skin of the breast and its natural form and prevents the psychological trauma associated with mastectomy. However, secondary reconstructions often have a higher satisfaction, since here no restitutio ad integrum is assumed. Alloplastic, i. e., implant-based, breast reconstruction and autologous breast reconstruction are complementary techniques. This article provides an overview of current options for breast reconstruction including patients' satisfaction and quality of life following breast reconstruction. Although immediate reconstruction is still the preferred choice of most patients and surgeons, delayed reconstruction does not appear to compromise clinical or patient-reported outcomes. Recent refinements in surgical techniques and autologous breast reconstruction include stacked-flaps, as well as microsurgical nerve coaptation to restore sensitivity, which lead to improved outcomes and quality of life. Nowadays Skin-sparing and nipple-sparing mastectomy, accompanied by improved implant quality, allows immediate prosthetic breast reconstruction as well as reemergence of the prepectoral implantation. The choice of breast reconstruction depends on the type of mastectomy, necessary radiation, individual risk factors, as well as the patient's habitus and wishes. Overall, recent developments in breast reconstruction led to an increase in patient satisfaction, quality of life and aesthetic outcome with oncological safety.

Abstract
INTRODUCTION Partner involvement in the decision-making process concerning breast reconstruction (BR) after a breast cancer diagnosis may be very supportive for the patient. So far, no study evaluates partner satisfaction with the outcome after BR and the relationship to patient satisfaction. The aim of this study was to assess and compare partner satisfaction of BR with autologous tissue (ABR) and prosthetic implants (IBR), respectively, and compare it to patient-reported outcomes. PATIENTS AND METHODS All patients undergoing ABR and IBR between January 2014 and December 2020 were asked to participate with their partners. Patient and partner satisfaction with breast reconstruction, overall outcome as well as patient's perceived and self-reported psychosocial well-being were evaluated using the Breast-Q and a modified partner questionnaire, respectively. RESULTS Fifty-three couples participated (IBR: n=30, ABR: n = 23). Patient and partner satisfaction with breast (r = 0.552), outcome (r = 0.465) as well as patient's perceived and self-report psychosocial well-being (r = 0.495) were highly correlated with partners scoring significantly higher (p<0.001). In terms of partner satisfaction, both reconstructive procedures achieved satisfactory results. ABR scored higher in terms of softness of breast and how natural the breast feels to touch whereas IBR was rated superior evaluating the breast size. CONCLUSION Both reconstructive procedures achieve satisfactory results in terms partner satisfaction whereas patient's psychosocial well-being was highly overestimated by their partners. Hence, partner inclusion in the regular psycho-oncological support might further sensitize them of the high psychological burden of a breast cancer diagnosis and therefore stabilize patients private support system.

Abstract
Background and Objectives: Lipofilling is a commonly performed procedure worldwide for breast augmentation and correction of breast contour deformities. In breast reconstruction, fat grafting has been used as a single reconstructive technique, as well as in combination with other procedures. The aim of the present study is to systematically review available studies in the literature describing the combination of implant-based breast reconstruction and fat grafting, focusing on safety, complications rate, surgical sessions needed to reach a satisfying reconstruction, and patient-reported outcomes. Materials and Methods: We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) throughout the whole review protocol. A systematic review of the literature up to April 2022 was performed using Medline, Embase, and Cochrane Library databases. Only studies dealing with implant-based breast reconstruction combined with fat grafting were included. Results: We screened 292 articles by title and abstract. Only 48 articles were assessed for full-text eligibility, and among those, 12 studies were eventually selected. We included a total of 753 breast reconstructions in 585 patients undergoing mastectomy or demolitive breast surgeries other than mastectomy (quadrantectomy, segmentectomy, or lumpectomy) due to breast cancer or genetic predisposition to breast cancer. Overall, the number of complications was 60 (7.9%). The mean volume of fat grafting per breast per session ranged from 59 to 313 mL. The mean number of lipofilling sessions per breast ranged from 1.3 to 3.2. Conclusions: Hybrid breast reconstruction shows similar short-term complications to standard implant-based reconstruction but with the potential to significantly decrease the risk of long-term complications. Moreover, patient satisfaction was achieved with a reasonably low number of lipofilling sessions (1.7 on average).

Abstract
Background: Breast reconstruction is currently performed as standard practice. Methods: A prospective study was performed of patients after total mastectomy who underwent autologous breast reconstruction with fat grafting (FG) combined with internal tissue expansion between September 2015 and December 2020. The patients were classified into groups A to F depending on the steps of breast reconstruction. Groups A and B described patients with completed breast reconstruction with FG and expander removal, with or without nipple/areola complex reconstruction. C described patients during deflation of the expander combined with simultaneous FG. D described patients after expander implantation and refilling. E described patients after first FG, and F included patients who discontinued reconstruction with the described method and converted to reconstruction with a breast implant. Results: Among 22 treated patients‚ two were after first FG (9.09%‚ group E), two were after expander implantation and refilling (9.09%‚ group D), three were during deflation of the expander combined with simultaneous FG (13.63%‚ group C), and four (18.18%) had completed breast reconstruction—two (9.09%) without NAC reconstruction and symmetrization (group B) and two (9.09%) with completed breast reconstruction (group A). In 11 patients (50%), breast reconstruction was abandoned after expander implantation and one to three FG procedures (group F), converting to breast reconstruction with a breast implant. Conclusions: This study demonstrated successful breast reconstruction using FG and expander implantation. Breast reconstruction using this method is safe and enables possible abandonment at any treatment stage, as well as conversion to breast reconstruction with implants.

Abstract
OBJECTIVE To date, breast reconstruction after mastectomy essentially uses flap- or prosthetic-based surgery. Autologous fat grafting (AFT) largely used in breast conservative surgery is considered an additional technique in breast reconstruction. The aim of this retrospective study was to report our experience of AFT as a stand-alone method for immediate breast reconstruction. PATIENTS AND METHODS Fifteen patients requiring a radical mastectomy underwent AFT for immediate reconstruction since 2014. Previous breast irradiation was not a contraindication. Procedures, complications, and cosmetic results were retrospectively analyzed. RESULTS Fifteen patients with an average age of 60.5 (43-78) years were included in this retrospective study. They had a body mass index ranging from 19 to 40. Fourteen had a mastectomy for cancer and 1 for prophylaxis. Nine received breast irradiation (7 before surgery and 2 adjuvant). A mean of 3 (2-6) AFT procedures were required to achieve total breast reconstruction. Except for the first transfer, others were performed as outpatient surgeries. Only 2 minor complications (1 hematoma and 1 abscess) not impairing results were reported. The results after a mean follow-up of 26 months were considered by the patients and surgeon as highly satisfactory even in previously irradiated breast, as assessed using a qualitative scoring analysis. CONCLUSIONS Autologous fat grafting as a stand-alone method for immediate breast reconstruction after radical mastectomy is a safe procedure with very consistent results even for patients requiring radiation therapy.

Abstract
Clinical results obtained when degradable polymer-based medical devices are used in breast reconstruction following mastectomy are promising. However, it remains challenging to develop a large scaffold structure capable of providing both sufficient external mechanical support and an internal cell-like environment to support breast tissue regeneration. We propose an internal-bra-like prototype to solve both challenges. The design combines a 3D-printed scaffold with knitted meshes and electrospun nanofibers and has properties suitable for both breast tissue regeneration and support of a silicone implant. Finite element analysis (FEA) was used to predict the macroscopic and microscopic stiffnesses of the proposed structure. The simulations show that introduction of the mesh leads to a macroscopic scaffold stiffness similar to the stiffness of breast tissue, and mechanical testing confirms that the introduction of more layers of mesh in the modular design results in a lower elastic modulus. The compressive modulus of the scaffold can be tailored within a range from hundreds of kPa to tens of kPa. Biaxial tensile testing reveals stiffening with increasing strain and indicates that rapid strain-induced softening occurs only within the first loading cycle. In addition, the microscopic local stiffness obtained from FEA simulations indicates that cells experience significant heterogeneous mechanical stimuli at different places in the scaffold and that the local mechanical stimulus generated by the strand surface is controlled by the elastic modulus of the polymer, rather than by the scaffold architecture. From in vitro experiments, it was observed that the addition of knitted mesh and an electrospun nanofiber layer to the scaffold significantly increased cell seeding efficiency, cell attachment, and proliferation compared to the 3D-printed scaffold alone. In summary, our results suggest that the proposed design strategy is promising for soft tissue engineering of scaffolds to assist breast reconstruction and regeneration.

Abstract
Lipofilling (LF) is a largely employed technique in reconstructive and esthetic breast surgery. Over the years, it has demonstrated to be extremely useful for treatment of soft tissue defects after demolitive or conservative breast cancer surgery and different procedures have been developed to improve the survival of transplanted fat graft. The regenerative potential of LF is attributed to the multipotent stem cells found in large quantity in adipose tissue. However, a growing body of pre-clinical evidence shows that adipocytes and adipose-derived stromal cells may have pro-tumorigenic potential. Despite no clear indication from clinical studies has demonstrated an increased risk of cancer recurrence upon LF, these observations challenge the oncologic safety of the procedure. This review aims to provide an updated overview of both the clinical and the pre-clinical indications to the suitability and safety of LF in breast oncological surgery. Cellular and molecular players in the crosstalk between adipose tissue and cancer are described, and heterogeneous contradictory results are discussed, highlighting that important issues still remain to be solved to get a clear understanding of LF safety in breast cancer patients.

Abstract
ABSTRACT Performing immediate breast reconstruction requires careful consideration of preoperative, intraoperative, and postoperative factors. One of the fundamental necessities is a well-coordinated multidisciplinary team to achieve successful reconstruction. Clear and effective communication between the oncological surgeon and plastic surgeon is imperative. The treatment plan must take into account any potential neoadjuvant and adjuvant therapies. Surgical planning and incisional approach must be carefully considered to optimize a safe oncologic surgery and ensure a viable reconstructive outcome. Furthermore, there are fundamentals to immediate breast reconstruction that must be met to obtain an aesthetically pleasing and structurally durable breast reconstruction. The goal of this article was to highlight important considerations in surgical planning and execution of immediate breast reconstruction so that an optimal outcome can be accomplished after either autologous or implant-based breast reconstruction.

Abstract
BACKGROUND Tissue expanders are widely utilized in plastic surgery. Traditional expanders usually are "inflatable balloons," which are planned to grow additional skin and/or to create space to be filled, for example, with an implant. In very recent years, reports suggest that negative pressure created by an external device (ie, Brava) induces both skin expansion and adipogenesis. OBJECTIVES The authors evaluated and assessed the adipogenetic potential of a novel internal tissue expander in an in vivo animal model. METHODS New Zealand female rabbits were enrolled in the study. A prototype spiral inner tissue expander was employed. It consisted of a-dynamic conic expander (DCE) with a valve at the end: when empty, it is flat (Archimedean spiral), whereas when filled with a fluid, it takes a conic shape. Inside the conic spiral, a negative pressure is therefore created. DCE is implanted flat under the latissimus dorsi muscle in experimental animals (rabbit) and then filled to reach the conical shape. Animals were investigated with magnetic resonance imaging, histology, and transmission electronic microscopy at 3, 6, and 12 months. RESULTS Magnetic resonance imaging revealed a marked increase in newly formed adipose tissue, reaching its highest amount at 12 months after the DCE implantation. Histology confirmed the existence of new adipocytes, whereas transmission electronic microscopy ultrastructure confirmed that most of these new cells were mature adipocytes. CONCLUSIONS Tensile stress, associated with negative-pressure expanders, generated newly white subcutaneous adipose tissue.

Abstract
Cosmetic Breast Augmentation without Silicone Implants Abstract. Cosmetic breast augmentation procedures without silicone implants are becoming increasingly popular. Mastopexy can be adapted to the needs of the patient and usually result in an at least optical augmentation. Lipofilling is a safe procedure in reconstructive and aesthetic breast surgery and can help to restore natural appearance, compensate volume deficiencies, and correct asymmetries, that may be congenital or a consequence of prior surgeries. Cosmetic breast augmentation of very small breasts or when aiming at higher breast volumes using lipofilling only are usually combined with procedures for tissue expansion in order to increase the take rate of the injected fat. Hyaluronic acid injections is no valid alternative and are not recommended for cosmetic breast augmentation.

Abstract
AbstractLipofilling has recently gained popularity as a tool in primary treatment of breast cancer, and its association with two-stage implant breast reconstruction is considered as standard treatment in many centers. However, no data are available about the long-term results of the association of lipofilling in combination with expander-implant reconstruction. A retrospective analysis was conducted on patients treated between January 2010 and December 2014. Two groups were compared. Group 1 had a standard expander-implant two-stage reconstruction. Group 2 underwent hybrid breast reconstruction (HBR). Patient characteristics, hospitalization, outcomes, reoperation details, outpatient visits, and evaluation questionnaires were taken into consideration. Intergroup comparison was performed using Wilcoxon Mann-Whitney U test and Pearson’s chi-square test or Fisher’s exact test for categorical variables. Two hundred fourteen patients were evaluated: 130 patients in group 1 and 84 patients in group 2. Group 2 showed significant benefits over group 1 in terms of capsular contracture rate, breast pain, and displacement/rotation of the implant (p = 0.005). The HBR protocol is associated with lower rate of capsular contracture, less breast pain at long follow-up times, and lower overall rates of revision surgery compared to standard expander-implant reconstruction. A specific cost analysis will help further clarify the advantages of this protocol over a standard procedure.Level of Evidence: Level III, risk/prognostic, therapeutic study.

Total Breast Reconstruction with Fat Grafting Combined with Internal Tissue Expansion. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2009.

Abstract
Supplemental Digital Content is available in the text. Breast reconstruction procedures are currently performed as standard practice and are an integral part of breast cancer treatment. The advantages and disadvantages of particular types of reconstruction are well known. Most of them require the woman to accept a different consistency of the reconstructed breast, as is the case with implants, or to have extra scarring in the donor site and a cutaneous island with a different texture in the recipient site, as is the case with TRAM, DIEP, and other flaps. This article presents the concept of breast reconstruction with fat grafting combined with internal tissue expansion. A 44-year-old woman after a right mastectomy for invasive carcinoma T1c, N0 (IIB) was presented. After unsatisfactory treatment with fat grafting supported by BRAVA system, she was qualified for breast reconstruction with fat grafting combined with tissue expansion. An anatomic 350 cm3 breast expander with an integrated port was implanted. It was filled with saline solution up to volume of 380 ml. Then, 7 fat grafting procedures combined with gradual emptying of the expander were performed. The 50/70 principle was used, that is, 50 ml of physiological saline was removed from the expander and 70 ml of fat was injected into the subcutaneous tissue over the expander. Finally, the expander was removed and a satisfactory volume and completely natural consistency of the breast was obtained. Breast reconstruction with fat grafting combined with tissue expansion is a promising method of total breast reconstruction after mastectomy.

Abstract
Reconstructive surgery aims to improve quality of life by recreating a natural-looking breast that is warm to the touch. To obtain symmetry and body contour alignment, restoration of volume within the skin envelope is mandatory. The chosen reconstruction technique depends on the characteristics of the diseased breast, the shape and volume of the contralateral breast, and the technical skills of the surgical team. Timing, type and different possibilities of breast reconstruction are discussed.
