Current Challenges in Breast Implantation

The Current State of the Art in Autologous Breast Reconstruction: A Review and Modern/Future Approaches

Background/Objectives: Modern breast reconstruction has undergone substantial evolution, with implant-based, pedicled autologous, and free autologous techniques. The purpose of this study is to review the current state of the art in free autologous breast reconstruction, highlighting advancements in the types of flaps, donor site selection, techniques, and functional restoration. Methods: A literature review was conducted using PubMed to capture studies related to well-known free flaps that are used for breast reconstruction. Studies for each flap type were reviewed and sorted for inclusion into one of six categories: (1) clinical outcomes, (2) comparison studies of alternative flaps, (3) preoperative planning, (4) flap classifications and perfusion zones, (5) technique descriptions, and (6) time and cost analyses. Results: The majority (77%) of articles included were written on various types of abdominally based free flaps, including TRAM, DIEP, and SIEA flaps. These studies indicated an evolution in technique over time to minimize donor site morbidity, improve patient-reported and functional outcomes, improve efficiency, and expand clinical indications. The remaining 23% of articles discussed alternative flap choices, including PAP, TUG, S/IGAP, and LAP flaps. Studies highlighted technical challenges and the evolution of techniques to make these flaps more accessible, as well as how to combine flaps to expand clinical indications. Conclusions: Autologous breast reconstruction has evolved significantly, with advancements in techniques such as robotic-assisted surgery, multi-flap reconstruction, bipedicled flaps, and neurotization. This review highlights the current best practices while acknowledging ongoing challenges and the potential for future innovations in microsurgery, nerve regeneration, and personalized medicine, which hold promise for further refining outcomes.

Breast Implants: Low Rate of Annual Check-Ups Results in Delayed Presentation of Ruptured Implants

Background: Breast-implant-based reconstruction is one of the most performed procedures in plastic surgery. Despite the high durability of breast implants, various complications are accompanied with prolonged inlay duration, particularly implant rupture. Many aftereffects can be associated with implant rupture, especially siliconoma and BIA-ALCL. Without regular implant check-ups, implant-related issues may remain underrecognized. Here, we analyzed the number of breast implant carriers needing revisions and if patients adhered to annual implant follow-up recommendations. Methods: We reviewed 1128 breast procedures at the department of plastic surgery at the University Clinic of St. Poelten between August 1st 2018 and December 31st 2023. Patients were analyzed to see whether regular check-ups of their breast implants were performed. Additionally, implant-related complications were investigated, as well as if they were noticed by implant carriers. Results: Only 15.46% of breasts implants were regularly checked at least once a year in our cohort. The remaining 84.54% of patients consulted our department due to pain or aesthetic discomfort without periodical follow-ups. Most implant ruptures (73.8%) were diagnosed in patients consulting acutely due to pain or capsular contraction after an average of 17.36 ± 10.57 years. Routine examination uncovered 26.2% of silent implant ruptures without patients yet complaining of clinical symptoms as early as 15.44 ± 11.17 years. Conclusions: Most implant ruptures develop clinical symptoms as an indicator that removal is warranted. However, only regular follow-ups can identify implant complications several years earlier and possibly reduce severe sequalae such as BIA-ALCL. This highlights the significance and necessity of annual breast implant controls by surgeons and radiologic imaging to prevent devastating implant-associated aftereffects.

Clinical Evaluation of Microbial Communities and Associated Biofilms with Breast Augmentation Failure

The incidence of breast implant illness (BII) and BII-related explant procedures has not decreased with current surgical and treatment techniques. It is speculated the main underlying cause of BII complications is the result of chronic, sub-clinical infections residing on and around the implant. The infection, and subsequent biofilm, produce antagonistic compounds that drive chronic inflammation and immune responses. In this study, the microbial communities in over 600 consecutive samples of infected explant capsules and tissues were identified via next-generation sequencing to identify any commonality between samples. The majority of the bacteria identified were Gram-positive, with Cutibacterium acnes and Staphylococcus epidermidis being the dominant organisms. No correlation between sample richness and implant filling was found. However, there was a significant correlation between sample richness and patient age. Due to the complex nature, breast augmentation failures may be better addressed from a holistic approach than one of limited scope.

Triplane technique for breast reconstruction after breast cancer surgery: A case series report

RATIONALE

Implant-based breast reconstruction is an important method for post-mastectomy breast reconstruction. Currently, the most commonly used technique is the biplane technique. However, the high rate of postoperative complications, the inability of pockets to accommodate larger implants, and the expensive costs of biological mesh make the development of new surgical methods urgent. The triplane technique for breast reconstruction is an ideal candidate method.

PATIENT CONCERNS

The main local symptoms were breast lump, abnormal breast skin, nipple discharge, and abnormal nipple or areola in 24 patients.

DIAGNOSES

The study included 24 female patients who underwent breast reconstruction using the triplane technique after radical breast cancer surgery.

INTERVENTIONS

The surgical procedure involved measuring the dimensions of the breast, designing the incision, and creating a pocket for the implant using the triplane technique, which includes the pectoralis major muscle, the pectoralis major fascia continuing to the rectus abdominis fascia, and the latissimus dorsa muscle fascia continuing to the rectus abdominis fascia. Postoperative follow-up included regular assessments of pain and evaluation of breast appearance.

OUTCOMES

No cases of postoperative infection were observed in all patients. During the 1-year follow-up period after surgery, 5 patients (20.8%) who needed radiotherapy after mastectomy for cancer showed slight darkening of skin flap pigment after using the triplane technique implant. No cases of exposure or infection of the expanders were reported, and 1 patient underwent expander replacement with a permanent prosthesis. All patients expressed satisfaction with the reconstructed breast shape. The 10 patients (41.7%) experiencing postoperative swelling and pain. However, the pain gradually subsided during the postoperative recovery period. No cases of local recurrence or distant metastasis of breast cancer were observed during the 1-year-follow-up period.

LESSONS

The triplane technique for breast reconstruction after breast cancer surgery provides good implant coverage, reduces the risk of complications, and is cost-effective.

Updated trends of breast implant surgeries: An Israeli analysis

INTRODUCTION

Breast augmentation remains one of the most prevalent procedures in plastic surgery. While most patients experience high satisfaction with the outcomes, a subset may encounter various complications or dissatisfaction with achieved results necessitating subsequent surgical intervention including implant removal or exchange.

MATERIALS AND METHODS

We collected information from three pivotal private medical centers in Israel where a considerable number of breast surgeries are performed. We examined the number of breast augmentations, implant exchange and implant removal surgeries with or without breast lift that were performed on a biannual basis for each center for the period 2018-2022. Trends in surgery types were analyzed and compared to registries in other countries.

RESULTS

Between the years 2018 and 2022, 20,075 surgeries were done in three main private medical centers in Israel. Data show a gradual increase in implant removal surgeries from 2018 (n = 80, 2.9%) to 2019 (n = 269, 9.9%), followed by a significant increase in 2020 (n = 1436, 27.3%), and a gradual decline between 2021 (n = 1019, 22.8%) and 2022 (n = 916, 18.5%). The overall number of breast implant insertion procedures (breast augmentation procedures and exchange procedures) was 2659 in 2018 (97%), 2424 in 2019 (90.0%), 3816 in 2020 (72.6%), 3437 in 2021 (77.1%), and 4019 in 2022 (81.4%).

SUMMARY

We present updated trends in breast implant surgeries in Israel. 2020 was a key year in which the rate of explantations was the highest, and the percentage rate of implantations was the lowest and a year in which the trend changed. These patterns partly align with trends seen in other countries worldwide.

Building Complex Autologous Breast Reconstruction Program: A Preliminary Experience

Autologous breast reconstruction is an increasingly popular method of reconstruction for breast cancer survivors. While deep inferior epigastric perforator (DIEP) flaps are the gold standard, not all patients are ideal candidates for DIEP flaps due to low BMI, body habitus, or previous abdominal surgery. In these patients, complex autologous breast reconstruction can be performed, but there is a limited number of programs around the world due to high technical demand. Given the increased demand and need for complex autologous flaps, it is critical to build programs to increase patient access and teach future microsurgeons. In this paper, we discuss the steps, pearls, and preliminary experience of building a complex autologous breast reconstruction program in a tertiary academic center. We performed a retrospective chart review of patients who underwent starting the year prior to the creation of our program. Since the start of our program, a total of 74 breast mounds have been reconstructed in 46 patients using 87 flaps. Over 23 months, there was a decrease in median surgical time for bilateral reconstruction by 124 min (p = 0.03), an increase in the number of co-surgeon cases by 66% (p < 0.01), and an increase in the number of complex autologous breast reconstruction by 42% (p < 0.01). Our study shows that a complex autologous breast reconstruction program can be successfully established using a multi-phase approach, including the development of a robust co-surgeon model. In addition, we found that a dedicated program leads to increased patient access, decreased operative time, and enhancement of trainee education.

Breastfeeding Outcome and Complications in Females With Breast Implants: A Systematic Review and Meta-Analysis

Breast augmentation is a commonly performed cosmetic procedure. We set out to determine whether there was any effect on breastfeeding in females after breast implants. The aim of this study was to perform a systematic review and meta-analysis of the current evidence on breastfeeding outcome and complications in females with breast augmentation. A systematic review was performed utilizing MEDLINE, EMBASE, and all evidence-based medicine reviews from their respective inception dates to November 7, 2022, to assess outcomes of breastfeeding in females with breast implants (PROSPERO ID: CRD42022357909). This review was in accordance with both the Cochrane Handbook for Systematic Review of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eleven studies (4 prospective and 7 retrospective) in total were included in the review. A total of 8197 out of 9965 (82.25%) patients were successfully able to breastfeed after breast implants. Of 5 studies that included a control group, 343,793 of 388,695 (88.45%) women without breast implants successfully breastfed. A meta-analysis of 5 comparative studies showed a significant reduction of breastfeeding in females with breast implants, n = 393,686, pooled odds ratio = 0.45 (95% CI, 0.38 to 0.53). Complications described included pain, mastitis, insufficient or excessive lactation, and nipple inversion. There may be impairment in ability to breastfeed for females who receive breast implants when compared with those without. Additional studies on the topic are needed to further clarify the relationship.

How Big Is Too Big? Exploring the Relationship between Breast Implant Volume and Postoperative Complication Rates in Primary Breast Augmentations

There is no consensus regarding implant size as an independent risk factor for complications in primary breast augmentation. Choosing appropriate implant volume is an integral part of the preoperative planning process. The current study aims to assess the relationship between implant size and the development of complications following augmentation mammaplasty.

Methods

A retrospective chart review of patients undergoing primary breast augmentation at the Westmount Institute of Plastic Surgery between January 2000 and December 2021 was conducted. Demographics, implant characteristics, surgical technique, postoperative complications, and follow-up times were recorded. Univariate logistic regression was used to identify independent predictors, which were then included in multivariate logistic regressions of implant volume and implant volume/body mass index (BMI) ratio regarding complications.

Results

A total of 1017 patients (2034 breasts) were included in this study. The average implant volume used was 321.4 ± 57.5 cm³ (range: 110-605). Increased volume and volume/BMI ratio were associated with a significant increase in risk of implant rupture (odds ratio = 1.012, P < 0.001 and 1.282, P < 0.001 respectively). Rates of asymmetry were significantly associated with increases in implant volume and volume/BMI ratio (odds ratio = 1.005, P = 0.004 and 1.151, P < 0.001, respectively). No single implant volume or volume/BMI ratio above which risks of complications significantly increase was identified.

Conclusions

Implant rupture and postoperative asymmetries are positively correlated with bigger implant volumes. Implant size could likely be a useful independent predictor of certain complications, especially in patients with high implant to BMI ratios.
