Hybrid Prepectoral Direct-to-Implant and Autologous Fat Graft Simultaneously in Immediate Breast Reconstruction: A Single Surgeon's Experience with 25 Breasts in 15 Consecutive Cases

Autologous Fat Grafting With CO2 Tissue Preparation (Carbo-pneumodissection): A Safe Method for Expanding and Enhancing Recipient Site Capacity and Aesthetic Outcomes

BACKGROUND

Autologous fat grafting (AFG) is commonly used as part of aesthetic and reconstruction procedures, but expanding and enhancing the recipient site capacity remains a major challenge.

OBJECTIVES

The aim of this study was to describe and assess an innovative intraoperative carbon dioxide (CO2) pneumodissection (CPD) recipient site preconditioning procedure intended to improve recipient site capacity and AFG outcomes.

METHODS

From June 2019 to August 2021, 53 patients after mastectomy or lumpectomy (76 breasts) underwent 96 AFG procedures as a separate stage immediately following tissue preconditioning with CPD.

RESULTS

There were no systemic or major local complications. The mean number of AFG procedures required to complete the reconstruction was 1.3 per breast. The vast majority of patients achieved a final satisfactory aesthetic outcome with either 1 or 2 procedures (77.6% and 18.4%, respectively). The volume of fat graft delivered into the recipient site per session following CPD was higher than previous literature reports for all study groups. Furthermore, the CPD procedure was associated with a reduced need for subsequent AFG to complete the reconstruction. The positive effect of CPD, in terms of AFG volume delivered, was even more prominent among scarred irradiated breasts. Despite the large fat graft volumes delivered in our study, only 5.3% of breasts experienced fat necrosis following the procedure.

CONCLUSIONS

CPD constitutes a safe, innovative, intraoperative method to expand and enhance recipient site capacity and fat grafting outcome. CPD allows cavernous expansion alongside preservation of the microcirculation. CPD works for both healthy and compromised tissues, in either reconstructive or aesthetic procedures.

Patient-Reported Outcomes After Autologous Fat Grafting in Prosthetic Breast Reconstruction: Prospective Cohort Study Using a Multivariate Analysis

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.

Outcomes in Hybrid Breast Reconstruction: A Systematic Review

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).

Implant-Based Breast Reconstruction after Mastectomy, from the Subpectoral to the Prepectoral Approach: An Evidence-Based Change of Mind?

Over the last years, prepectoral implant-based breast reconstruction has undergone a renaissance due to several technical advancements regarding mastectomy techniques and surgical approaches for the placement and soft tissue coverage of silicone implants. Initially abandoned due to the high incidence of complications, such as capsular contraction, implant extrusion, and poor aesthetic outcome, the effective prevention of these types of complications led to the prepectoral technique coming back in style for the ease of implant placement and the conservation of the pectoralis muscle function. Additional advantages such as a decrease of postoperative pain, animation deformity, and operative time contribute to the steady gain in popularity. This review aims to summarize the factors influencing the trend towards prepectoral implant-based breast reconstruction and to discuss the challenges and prospects related to this operative approach.
