Revision Breast Augmentation

Recognizing and Managing Breast Implant Complications: A Review for Healthcare Providers Who Treat Women Who Underwent Breast Implant-Based Surgery

Given the prevalence of breast implants, healthcare providers treating women should be familiar with potential complications that may result from breast augmentation and implant-based reconstruction surgeries and the appropriate management strategies to adopt for each. Familiarity with risk factors and variables involved in complications and an understanding of the patient's surgical history and implant type/characteristics is key. This article provides an overview of implant types and surgical approaches and potential complications related to surgery that physicians treating women may encounter during routine clinical practice. It describes potential implant complications such as hematoma, implant rupture, infection, seroma, rare capsular lymphomas, capsular contracture, implant malposition, rippling, and animation deformity. This article also describes systemic symptoms that patients sometimes attribute to breast implants, such as fatigue, brain fog, joint pain, anxiety, hair loss, depression, rash, autoimmune diseases, inflammation, or gastrointestinal symptoms. Rare conditions, such as breast implant-associated anaplastic large cell lymphoma and squamous cell carcinoma in the capsule around breast implants, are also presented. Diagnostic criteria are summarized, with photographic examples, and management strategies and referral recommendations across the range of potential complications are provided. This article provides information to support healthcare providers who treat women in detecting breast implant complications and guiding their patients to an appropriate treatment and referral strategy.

Protocol for single-arm clinical trial evaluating medical grade polycaprolactone breast scaffold implantation with autologous fat grafting for breast implant revision and congenital defect correction surgery

INTRODUCTION

Revision surgery following primary breast augmentation is common due to well-reported long-term limitations of permanent silicone implants. There are limited options for revision breast augmentation which avoids using silicone implants. Scaffold-guided breast tissue engineering (SGBTE) is a novel technique which uses breast scaffolds additively manufactured from medical grade polycaprolactone (mPCL), which is implanted and filled with autologous fat graft. This approach avoids limitations as observed with permanent silicone breast implants as the scaffold is porous and biodegradable. This clinical trial evaluates the safety and efficacy of SGBTE.

METHODS AND ANALYSIS

This study is an open, single-arm, monocentric, interventional, prospective clinical trial. The trial is being conducted at the Royal Brisbane and Women's Hospital (RBWH) in Herston (Queensland, Australia) of the Metro North Health Service. The trial investigates 15-20 women who require breast implant surgery and/or congenital breast defect correction surgery, where a mPCL breast scaffold is implanted and filled with autologous fat graft. The primary endpoint is postoperative device safety by assessing the rate of adverse device effect rate. Secondary endpoints include general adverse event frequency and severity, number of revision surgeries, general surgical outcomes and complications, patient-reported outcomes and volume replacement outcomes.

ETHICS AND DISSEMINATION

The RBWH Human Research Ethics Committee (EC00172) has approved this clinical trial (ethics approval: HREC/2021/QRBW/79906). Findings from this clinical trial will evaluate the safety and efficacy of implanting mPCL scaffolds filled with autologous fat graft. The results of this clinical trial will be published in a peer-reviewed journal and presented at scientific meetings.

TRIAL REGISTRATION NUMBER

NCT05437757.

Safety of Combined Versus Isolated Cosmetic Breast Surgery and Abdominoplasty: Insights from a Multi-institutional Database

INTRODUCTION

Abdominoplasty and breast surgery are popular cosmetic procedures, often performed as stand-alone or combined procedures. However, the safety of combining these surgeries remains poorly understood.

METHODS

We analyzed data from the ACS-NSQIP database spanning 2008-2021, focusing on patients who underwent isolated cosmetic breast surgery, isolated cosmetic abdominoplasty, or the combination of both. We evaluated four primary outcomes: general complications (reoperation, readmission, mortality), surgical complications, medical complications, and overall complications (general + surgical + medical). Further analysis considered the specific type of cosmetic breast surgery.

RESULTS

A total of 7865 female patients were identified, of whom 20.5% underwent isolated abdominoplasty, 65.3% cosmetic breast surgery, and 14.2% combined abdominoplasty with concurrent cosmetic breast surgery. Combined surgery was associated with a significantly higher risk of reoperations (OR 2.07; p = 0.04) compared to abdominoplasty alone. However, there was no significant difference in overall complications (OR 1.17; p = 0.40), surgical complications (OR 0.72; p = 0.26), or medical complications (OR 0.97; p = 0.91) between these two groups. Comparing combined to isolated cosmetic breast surgery, there was a higher risk of overall complications (OR 1.70; p = 0.04) and medical complications (OR 5.30; p < 0.0001) but no significant difference in general complications (OR 1.40; p = 0.33) or surgical complications (OR 0.85; p = 0.73).

CONCLUSION

Combining breast surgery with abdominoplasty increases the risk of reoperations but does not elevate the risk of surgical or medical complications. However, patients seeking combined surgeries are more likely to experience adverse events than those seeking isolated cosmetic breast surgery.

Secondary Breast Augmentation: The Six Winning Moves

BACKGROUND

Breast augmentation in 2019 was the first among the top five cosmetic surgical procedures performed worldwide, according to the International Society of Aesthetic Plastic Surgery. It is not only the most commonly performed cosmetic surgery, but also the aesthetic procedure with the highest reoperation rate.

METHODS

A retrospective observational study of 306 female patients who underwent secondary breast surgery, with a follow-up of at least 1 year after surgery, from 2010 to 2020 is presented. For patients'selection, we decided to include all patients who performed a secondary breast surgery for aesthetic reasons; only patients with history of previous radiotherapy were excluded.

RESULTS

Patients were divided into different groups according to the performed procedure (the six winning moves) and associated postoperative outcomes are shown.

CONCLUSIONS

The aim of this paper, based on authors' own experience, is to present a personalized approach to secondary breast reshaping, describing the six "winning" moves to apply, which, differently combined among each other, intend to address each specific cause of reintervention with a dedicated surgical procedure.

A Comparison Between Two-Dimensional and Three-Dimensional Endoscopic Imaging for Breast Augmentation

Background This study aimed to compare the reoperation rates between two-dimensional (2D) and three-dimensional (3D) endoscopic imaging used for breast augmentation. Methodology The medical records of females who underwent primary or revision breast augmentation surgery at our clinic from January 2014 to December 2023 were retrospectively reviewed. From January 2016 to August 2022, endoscopic operations were performed under 2D imaging, and from September 2022 onward, operations were performed using a novel synthetic 3D imaging technique (Monostereo®). All operations were performed by the same surgeon. The reoperation rate and other study variables between the two groups were compared. Results A total of 351 female patients (median age = 33 years) were included, of whom 216 had surgery using 2D imaging and 135 had surgery using 3D imaging. The overall reoperation rate was 4.3% (15/351), and it was significantly lower in the 3D imaging group compared to the 2D imaging group (14/216 (6.5%) vs. 1/135 (0.7%); p = 0.01). Age, incision site, placement, implant surface type, or surgery time had no association with reoperation. However, patients who required reoperation had a significantly larger implant size (330 (300-360) mL) than those who did not require a reoperation (275 (270-325) mL) (p < 0.05). Capsular contracture was the reason for 60% (n = 9) of the reoperations, and 40% (n = 6) of the reoperations were a size change requested by the patients. Conclusions Breast augmentation using the novel synthetic 3D imaging technique is associated with a lower reoperation rate compared to conventional 2D imaging. Further investigation is needed to examine the benefits of 3D imaging for breast augmentation.

COVID-19 Infection and Vaccination Effects on Breast Implant Illness: A Case Report

Breast implant illness (BII) is a term used to describe a range of symptoms associated with silicone breast implants. This condition suggests that silicone may trigger symptoms in individuals who are immunologically predisposed, and the spectrum of symptoms may be linked to autonomic dysregulation in these patients. We present the case of a female patient in her mid-40s with a history of autoimmune thyroiditis who had not required prior therapy. She underwent breast augmentation and subsequently developed gradual difficulties. After recovering from a COVID-19 infection, her nonspecific symptoms, consistent with BII, worsened. These symptoms included chronic fatigue, hair loss, dry skin, petechiae, low-grade fever, and frequent urination. Additionally, she developed symptoms associated with long COVID. A subsequent Pfizer-BioNTech COVID-19 vaccination further exacerbated her symptoms and overall condition. Due to the broad spectrum of nonspecific symptoms, the patient underwent numerous screenings over an 18-month period, which were inconclusive. We hypothesize that the vaccination and previous infection had a synergistic effect on her ongoing BII symptoms, contributing to the worsening of her condition. An isolated right-sided seroma with left-sided lymphadenopathy appeared to be a side effect of the vaccine. Additionally, the patient developed a newly diagnosed allergy to polyethylene glycol and other allergic manifestations, such as chronic urticaria, which are consistent with autonomic nervous system dysregulation and long COVID. These symptoms resolved within three weeks of explantation with en bloc capsulectomy. It is noteworthy that the patient was unaware of BII until an MRI revealed a suspected intracapsular implant rupture on the right side, which led to the decision to remove the implants.

Acute and chronic mammary periprosthetic histological changes of the muscle

Background

Augmentation mammoplasty with subpectoral prosthesis implantation is a frequent performed procedure in plastic surgery for reconstructive and aesthetic purposes. Although prosthesis implantation in a pocket under the major pectoralis muscle has been related to volumetric and functional alterations, there is not much information about the associated short- and long-term histological changes. Therefore, the aim of our study was to describe the acute and chronic histological muscle alterations associated with subpectoral prosthesis implantation.

Materials and Method

We collected samples from patients with breast tissue expander (<6 months after implantation) and prosthesis (>1 year after implantation) and from patients without implantation as a control group. The samples were processed for assessing their histological, histochemical and immunohistochemical properties.

Results

In the control group, no relevant histological findings were identified. Additionally, in the patients with expander, we observed mild augmentation of the internalised nuclei, normal morphology, significant muscle atrophy and fibrosis, whereas in the patients with prosthesis considerable augmentation of internalised nuclei, significant muscle atrophy, fibrosis and alteration of normal muscle morphology were observed.

Conclusion

Prosthesis implantation induces histological changes in the periprosthetic striated muscle. Chronic fibrosis and inflammation play key roles in this process, which should be characterised in more detail from the histological and molecular biological perspective.

Augmentation-Mastopexy With 4-Layer Autologous Fat Grafting and Evaluation of Viability With MRI

Background

Autologous fat (AF) grafting is widely used in plastic surgery and is generally considered a safe and effective procedure. A combined approach utilizing vibration amplification of sound energy at resonance (VASER) to prepare AF grafts with a 4-layer fat grafting technique was explored in this study.

Objectives

To offer a customized solution that accommodates individual anatomical differences.

Methods

This retrospective, cross-sectional case series involved 40 breasts from 20 female patients who underwent primary augmentation-mastopexy. After removing excess breast tissue and exposing the pedicle, lateral pillars, and pectoral muscle, the 4-layer fat grafting was performed as follows: 150 mL of AF under the pectoral muscle directed toward the medial and central zones; 100 mL into the pectoral muscle toward these zones; 50 mL under the pectoral fascia, moving retrograde from cephalic to caudal portions at a 30° to 45° cannula angle. After closing the epithelial and subepithelial incisions, an additional 100 to 150 mL of AF was injected under the subcutaneous layer around the breast, depending on each patient's contour and breast shape. Patients were monitored for 2 years with MRI scans to assess breast volume, anatomy, and fat graft survival.

Results

The average follow-up was 26 ± 2.81 months. MRI evaluations indicated an efficient survival rate of the fat grafts. None of the patients experienced minor or major complications.

Conclusions

The 4-layer AF grafting technique appears to be a safe and effective procedure for customized breast sculpting in augmentation-mastopexy surgery, with a high rate of fat graft sustainability and survival.

Impact of post-operative infection on revision procedures in breast reconstruction: A marketscan database analysis

BACKGROUND

Esthetic complications, such as capsular contracture and soft-tissue contour defects, hinder the desired outcomes of breast reconstruction. As subclinical infection is a prevailing theory behind capsular contracture, we investigated the effects of post-operative infections on these issues and revision procedures.

METHODS

We conducted a retrospective database study (2007-2021) on breast reconstruction patients from the MarketScan® Databases. Esthetic complications were defined by their associated revision procedures and queried via CPT codes. Severe capsular contracture (Grade 3-4) was defined as requiring capsulotomy or capsulectomy with implant removal or replacement. Moderate and severe soft-tissue defects were determined by the need for fat grafting or breast revision, respectively. Generalized linear models were used, adjusting for comorbidities and surgical factors (p < 0.05).

RESULTS

We analyzed the data on 62,510 eligible patients. Post-operative infections increased the odds of capsulotomy (OR 1.59, p < 0.001) and capsulectomy (OR 2.30, p < 0.001). They also raised the odds of breast revision for severe soft-tissue defects (OR 1.21, p < 0.001). There was no significant association between infections and fat grafting for moderate defects. Patients who had post-operative infections were also more likely to experience another infection after fat grafting (OR 3.39, p = 0.0018). In two-stage reconstruction, infection after tissue expander placement was associated with greater odds of infection after implant placement.

CONCLUSION

Post-operative infections increase the likelihood of developing severe soft-tissue defects and capsular contracture requiring surgical revision. Our data reinforce the role of infections in the pathophysiology of capsular contracture. Additionally, infections elevate the risk of subsequent infections after fat grafting for moderate defects, further increasing patient morbidity.

Feminizing Gender Affirming Breast Surgery: Procedural Outcomes at a Single Academic Institution

Background

Implant-based breast augmentation is a gold standard procedure for transfeminine patients to create a more feminine-appearing chest. In many cases, ancillary procedures are performed simultaneously to achieve an optimal aesthetic result.

Objectives

To determine the clinical outcomes of patients undergoing feminizing gender-affirming breast surgery in a single academic institution.

Methods

A retrospective electronic chart review of feminizing gender-affirming breast surgery patients at Mayo Clinic, Rochester, from 2017 to 2022 was conducted. Patients' demographics and surgical outcomes were gathered. A survival analysis was performed to obtain the time-to-event complication rate.

Results

Over 5 years, 46 patients (92 breasts) were included. The mean age was 39 years (standard deviation [SD] ±15), and most had an above-normal body mass index (BMI) (58.7%). Thirty (65%) had previous gender-affirming surgeries. The mean implant volume was 289 mL (SD ±95; 140-520). Most implants were placed in a subglandular plane (81%) with an inframammary fold incision (91.3%). All implants used were smooth, round cohesive silicone gel implants. Ancillary procedures were performed in 32 patients (69.57%). Eight patients presented complications (4 major vs 4 minor) in a median postoperative follow-up of 372 vs 392 days; at 1-month follow-up, the probability of a complication having occurred is 2.17% (95% CI: 0%-6.3%) vs 5% (95% CI: 0%-11.5%), and at 1 year, the probability is 10.21% (95% CI: 0%-20.9%) vs 12.5% (95% CI: 0%-23.4%), which remains the same up to 4 years.

Conclusions

Breast augmentation with implants is a safe procedure to achieve feminization of the breast with a low rate of complications.

Breast Conserving Therapy for Patients With Prior Cosmetic Implant-Based Breast Augmentation: Outcomes and Comparison Against a Matched Cohort

INTRODUCTION

Controversy exists regarding potential increased toxic effects in patients with cosmetic implant-based augmentation (CIBA) who receive radiation therapy. We evaluated acute and chronic toxic effects associated with radiation therapy in women with prior CIBA treated with whole-breast irradiation (WBI) as part of breast conserving therapy (BCT) and compared these results against a cohort of patients without prior breast augmentation who received similar therapy.

METHODS

A retrospective review was performed to identify patients with a prior history of CIBA who subsequently underwent BCT with WBI. The control group consisted of consecutively treated patients without prior CIBA who also underwent BCT with WBI. Analyses included a comparison of baseline and treatment-associated factors between the augmentation and control groups, evaluation of toxic effects between both groups, and multivariable analysis of factors associated with the receipt of additional surgery following radiation.

RESULTS

Thirty-six patients with prior CIBA and 135 consecutively treated patients without CIBA were identified. Patients with prior CIBA were treated from 2006 through 2019, and patients without CIBA were treated from 2016 through 2019, though treatment characteristics and median follow-up time were similar between the two groups. Patients with prior CIBA were significantly less likely to experience acute moist desquamation (0% vs. 18%; P = .005). There were otherwise no statistically significant differences in acute (≤ 6 months) or chronic (> 6 months) toxic effects between the two groups. Rates of excellent/good chronic cosmetic outcome were 89% for the CIBA group and 97% in the control group (P = .094). On multivariable analysis, patients without prior CIBA (OR = 0.04; CI = 0.01-0.13; P < .001) and patients treated with moderately hypofractionated irradiation (OR = 0.08; CI = 0.02-0.23; P < .001) were significantly less likely to undergo additional surgery following receipt of WBI. Two patients experienced implant loss following radiation therapy.

CONCLUSIONS

WBI as part of BCT in patients with prior implant-based breast augmentation appears safe and is associated with favorable cosmetic outcomes. There was an increased need for additional surgery in patients with prior CIBA, but rates of acute and chronic toxic effects appeared similar to those in nonaugmented patients.

An Evaluation of Native Breast Dimension and Tissue Expander Inflation Rate on the Risk of Capsular Contracture Development in Postmastectomy Reconstruction

INTRODUCTION

Capsular contracture is a common complication after 2-stage breast reconstruction. The relationships between native breast size, the rate of tissue expander expansion, and capsule formation have not been elucidated. This study aims to evaluate how these factors contribute to capsular contracture and establish cutoff values for increased risk.

METHODS

A data set consisting of 229 patients who underwent 2-stage breast reconstruction between 2012 and 2021 was included in the study. The rate of expansion is estimated as the final expanded volume subtracted by the initial filling volume of the tissue expander over time elapsed. The native breast size was estimated using various preoperative breast measurements and the weight of mastectomy specimen (grams). Further stratified analysis evaluated patients separately based on postoperative radiation status.

RESULTS

Greater nipple-inframammary fold distance and faster tissue expander enlargement rate conferred decreased odds of developing capsular contracture ( P < 0.05). On stratified analysis, faster tissue expansion rate was not significant in the nonradiated cohort but remained a significant negative predictor in the radiation group (odds ratio, 0.996; P < 0.05). Cut-point analysis showed an expansion rate of <240 mL/mo and a nipple-inframammary fold value of <10.5 cm as conferring a greater risk of capsular contracture.

CONCLUSION

Smaller inframammary fold distance may be associated with a higher risk of capsular contracture. Slower expansion rates correlate with increased odds of contracture in patients undergoing adjuvant radiation. Breast geometry should be considered when risk stratifying various reconstruction approaches (implant vs autologous). In addition, longer delays between implant exchange and initial tissue expansion should be avoided if clinically feasible.

A bibliometric and visualized study on global trends of breast augmentation complications, 2011-2021

Background

Women undergo breast augmentation surgery for a variety of reasons, but surgical complications can seriously affect patient outcomes and quality of life, making it a hot research topic. Although a large body of literature exists in this field, a lack of systemic generalization hinders the ability to guide clinical practice. We aimed to identify the current research hotspots and common surgical approaches of breast augmentation and to predict future research hotspots by analyzing the literature of the past 10 years.

Methods

All relevant literature on breast augmentation complications were screened in the Web of Science (WoS) platform from 2011 to 2021. We analyzed the research within this field using the software programs VOSviewer and CiteSpace.

Results

In total, 2,798 publications were selected. The United States ranked first in the world (1,173 articles), followed by Italy (243 articles), and the United Kingdom (208 articles). Memorial Sloan Kettering Cancer Center was the institution with the most publications, but the academic achievements of Harvard were the most recognized. Plastic and Reconstructive Surgery was the most prominent of all journals in terms of both the number and quality of the articles published. Albornoz was the hub author in the co-citation network. Keyword cluster analysis showed that capsular contracture, breast cancer, and postoperative nausea, among others, were the hotspots and trends of research in recent years.

Conclusions

This study comprehensively summarized and analyzed the research trends of breast augmentation complications worldwide. Capsular contracture and postoperative nausea are current research hotspots. Periareolar incision and the breast crease incision are the most common incision approaches. Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a future research hotspot.

Trends in Breast Augmentation Research: A Bibliometric Analysis

BACKGROUND

Breast augmentation is one of the most demanded procedures in plastic surgery and one of the most commonly performed by plastic surgeons. However, a bibliometric analysis of breast augmentation has not been published in recent years. The current study aimed to use a bibliometric analysis to conduct a qualitative and quantitative evaluation of breast augmentation research and provide the research trends and hotspots in this field.

METHODS

Publications on breast augmentation research were extracted from the Web of Science core collection database. VOSviewer 1.6.18 was used to assess co-authorship, co-occurrence, citation of countries, institutions, authors, and journals, as well as hotspot keywords.

RESULTS

On February 8, 2022, 4637 records of breast augmentation research published from 1985 to 2021 were collected. The bulk of the retrieved studies were original research articles (n = 2235, 48.20%). A total of 1053 (22.71%) papers were open access. The annual publication output increased annually. The USA was the driving force in this field and had a strong academic reputation. The top-contributing institution was the University of Texas MD Anderson Cancer Center (2.37%, with 110 publications). Plastic and reconstructive surgery (998 publications, 21.52%) published the most research in this field and was also the most frequently co-cited journal (22,351 citations, total link strength (TLS): 409,301). Clemens MW (68 publications, 1.47%) was the most prolific author, and Spear SL (1456 citations, TLS: 27,231) was the most frequently co-cited author. The research hotspots included the following four aspects: safety and effectiveness of breast implants, implant-based breast reconstruction, breast cancer incidence after breast implantation, and breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL). The research trends were BIA-ALCL, implant-based breast reconstruction, BREAST-Q, acellular dermal matrix, capsular contracture, and autologous fat grafting.

CONCLUSION

The present study provides a panoramic view of breast augmentation research in plastic and reconstructive surgery. This novel comprehensive bibliometric analysis can help researchers and nonresearchers alike to rapidly identify the potential partners, research hotspots, and research trends within their areas of interest.
