Abstract
BACKGROUND Capsular contracture is one of the most frequent indications for revision following breast augmentation. Management goals focus on restoring breast aesthetics and minimizing subsequent recurrence of capsular contracture. As new data emerge, close review of the data are merited to build evidence-based clinical guidelines to inform surgical practice and management of capsular contracture. METHODS A systematic review of the MEDLINE, Embase, and Cochrane Database of Systematic Reviews databases was conducted to characterize the surgical management of capsular contracture in revision breast augmentations. The primary endpoint was capsular contracture recurrence rate. RESULTS The review was conducted in November of 2021. Primary search revealed 14,163 results. Initial screening by title left 1223 articles. Abstract review left 90 articles for full-text review, of which 34 were ultimately included and were all observational in nature. CONCLUSIONS Capsular contracture management remains an important topic, with limited high-level evidence for establishing clear evidence-based treatment guidelines. Although more evidence is required to assess the effects of capsulectomy, implant exchange, and plane change, these appear to be useful mechanisms for reducing recurrent capsular contracture. There is more evidence regarding the use of acellular dermal matrix, although this still requires long-term follow-up studies. New developments regarding textured implants limit the revision breast augmentation surgeon to smooth devices.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Understand how bacteria negatively impact aesthetic and reconstructive breast implants. 2. Understand how bacteria infect breast implants. 3. Understand the evidence associated with common implant infection-prevention strategies, and their limitations. 4. Understand why implementation of bacteria-mitigation strategies such as antibiotic administration or "no-touch" techniques may not indefinitely prevent breast implant infection. SUMMARY Bacterial infection of aesthetic and reconstructive breast implants is a common and expensive problem. Subacute infections or chronic capsular contractures leading to device explantation are the most commonly documented sequelae. Although bench and translational research underscores the complexities of implant-associated infection, high-quality studies with adequate power, control groups, and duration of follow-up are lacking. Common strategies to minimize infections use antibiotics-administered systemically, in the breast implant pocket, or by directly bathing the implant before insertion-to limit bacterial contamination. Limiting contact between the implant and skin or breast parenchyma represents an additional common strategy. The clinical prevention of breast implant infection is challenged by the clean-contaminated nature of breast parenchyma, and the variable behavior of not only specific bacterial species but also their strains. These factors impact bacterial virulence and antibiotic resistance.

Abstract
BACKGROUND Capsular contracture (CC) remains the most common complication of implant-based aesthetic and reconstructive breast surgery. With subclinical infection proven to be the primary etiology, antimicrobial breast pocket irrigation has been recommended as the key step to reduce CC but has not been universally adopted. OBJECTIVES The purpose of this study was to review the rates of CC observed when applying proven antimicrobial breast pocket irrigations. METHODS Data from patients undergoing cosmetic breast augmentation were recorded prospectively from 1997 to 2017. The irrigation was performed with either a Betadine-containing (50% Betadine or "Betadine triple") or a non-Betadine triple antibiotic regimen. The database was assessed to determine the type of implant used, the incidence of CC, and possible contributing factors. The degree of CC was recorded according to the Baker classification. RESULTS A 20-year prospective data collection yielded 2088 patients with 4176 implants; of these patients, 826 had textured implants and 1262 had smooth implants. The incidence of Grade III/IV CC was found to be 0.57% in all patients undergoing primary breast augmentation (1.21% in textured implants and 0.16% in smooth implants). CONCLUSIONS This study constitutes the largest and longest review of CC in a controlled, single-surgeon setting. The incidence of CC is low and reinforces the efficacy/utility of antimicrobial breast pocket irrigation. Both the Betadine and non-Betadine antibiotic regimens were found to be effective, with the Betadine regimen being preferred. Universal adoption of Betadine-containing antimicrobial breast pocket irrigation is recommended to reduce CC and other device-associated infections. LEVEL OF EVIDENCE: 4

Abstract
Silicone breast implants are commonly used for cosmetic and oncologic surgical indications owing to their inertness and being nontoxic. However, complications including capsular contracture and anaplastic large cell lymphoma have been associated with certain breast implant surfaces over time. Novel implant surfaces and modifications of existing ones can directly impact cell-surface interactions and enhance biocompatibility and integration. The extent of foreign body response induced by breast implants influence implant success and integration into the body. This review highlights recent advances in breast implant surface technologies including modifications of implant surface topography and chemistry and effects on protein adsorption, and cell adhesion. A comprehensive online literature search was performed for relevant articles using the following keywords silicone breast implants, foreign body response, cell adhesion, protein adsorption, and cell-surface interaction. Properties of silicone breast implants impacting cell-material interactions including surface roughness, wettability, and stiffness, are discussed. Recent studies highlighting both silicone implant surface activation strategies and modifications to enhance biocompatibility in order to prevent capsular contracture formation and development of anaplastic large cell lymphoma are presented. Overall, breast implant surface modifications are being extensively investigated in order to improve implant biocompatibility to cater for increased demand for both cosmetic and oncologic surgeries.

Abstract
BACKGROUND The precise etiology and treatment for capsular contracture remains uncertain at least partially due to the fact that there is no reliable quantitative measurement tool. To address this, it is postulated that the surface area of an implant as defined by the surrounding pocket may provide a quantifiable variable that can be measured to evaluate the degree of capsular contracture. METHODS A bench model for capsular contracture was developed. The surface area of a series of spherical test objects and non-contracted and contracted breast implants was measured using a wax coating technique as well as three-dimensional reconstructions created from CT scan images. RESULTS Comparison of the mathematically calculated surface areas to the wax and CT results for spheres of known dimension provided nearly identical values documenting the accuracy of the two experimental methods. Comparison of the surface area measurements between the test groups showed that the average decrease in surface area for all implants was 20%, ranging from a high of 30.9% for a low profile implant to a low of 14.1 % for a high profile implant. The anatomically shaped devices demonstrated nearly uniform degrees of surface area change over three different heights with volume and projection held relatively constant. CONCLUSIONS The described bench model provides a useful tool for the study of capsular contracture. Surface area is a descriptive variable that can assess the degree of capsular contracture that is present. A classification system based on surface area is presented.

Abstract
Silicone implants are frequently used for breast augmentation and reconstruction. However, late complication, such as capsular contracture, remain the most important side effect. In this study we compare different methods for reducing the inflammatory reaction around the silicone implant by introducing one microtextured breast implant in wistar rats. The rats were dividing in 4 groups: the first one was the control group that received untreated implant; in the second we used silicone implants impregnated with rifampin solution, the third one had implant combined with intramuscular dexamethasone injection and the last one had silicone implant associated with autologous centrifuged fat introduced in the implant pocket. The implants and the capsular tissue surrounding were removed after eight weeks. Capsule samples were submitted to histological evaluations. The present study demonstrated that fat grafting may have a role in reducing and preventing capsular contractures after breast augmentation with silicone implants by decreasing the inflammatory process.

Abstract
BACKGROUND Breast augmentation is one of the most commonly requested and performed plastic surgery procedures. In order to prevent early postoperative complications such as seroma or hematoma, surgical drains could be useful. The aim is to perform a systematic review of the literature on the use of surgical drains in primary breast augmentation. METHODS This review was performed following the PRISMA guidelines. PubMed, SCOPUS, Web of Science and Cochrane Library databases were queried in search of clinical studies describing the use of surgical drains in women undergoing primary breast augmentation with implants and documenting seroma and/or hematoma formation rate and/or infection rate. RESULTS Initial search identified 2596 studies, and 162 were found relevant. Full-text review and application of our inclusion criteria to all retrieved papers produced 38 articles that met inclusion criteria. Among the included studies, 16 papers reported the use of surgical drains in breast augmentation, while in the remaining 22 articles drains were not used. Only 5 studies specifically investigated the role and effectiveness of surgical drains in augmentation mammaplasty and its possible relationship with complication rate such as seroma, hematoma or infection. CONCLUSIONS Despite similar complication rates emerged from the analyzed articles, because of the heterogeneity of the studies, we were not able to demonstrate specifically whether drain use affects the rate of early postoperative complications such as seroma, hematoma and infection. Additional randomized controlled trials are strongly advocated in order to provide the necessary scientific evidence.

Abstract
Background: Capsular contracture is common in breast augmentation and reconstruction surgery. The present systematic review discusses the safety of textured and smooth implants in the submuscular position. Methods: A literature search was conducted on PubMed and EMBASE from inception until June 2020. The primary outcome was reduction of capsular contracture (Baker grade); others included time of capsular contracture onset, implant position/rupture rate/surface, hematoma/seroma risk, surgeon assessment and patient satisfaction. A total of 7731 patients were included from six publications. Results: The overall risk rate for capsular contracture increased from 7.6 to 25% in 10 years. The capsular contracture rates in textured and smooth implants were 3-14% and 6-20%, respectively, and no significant difference between implants was observed when the implants were placed submuscularly. Submuscular placement and textured implants also reduced the incidence of other complications. Conclusion: This systematic review suggests that appropriate placement reduces capsular contracture rate, irrespective of implant surface.

Abstract
BACKGROUND While the risks and benefits of smooth versus textured implants for breast reconstruction and primary breast augmentation are thoroughly supported in the literature, few studies have examined the relationship between implant shell texture and complications following direct-to-implant (DTI) breast reconstruction. OBJECTIVES The present study examines the relationship between implant shell texture and complications in patients receiving DTI breast reconstruction. METHODS Retrospective chart review of patients undergoing DTI breast reconstruction between 2011 and 2018 by a single surgeon was performed. A propensity score matching algorithm was used to eliminate unwanted bias stemming from clinical covariates. Chi-squared and Fisher's exact tests were used to examine the association between implant shell texture and the following major postoperative complications: capsular contracture, hematoma, seroma, necrosis, infection, and implant loss. RESULTS A total of 402 unique patients (751 breasts) were included. The majority received smooth implants compared with textured implants (80.3% vs. 19.7%, respectively); 444 breasts were included for comparative analysis after 2:1 propensity score matching (296 smooth implants, 148 textured implants). The only statistically significant difference in outcomes between the two groups was a higher incidence of hematoma in the textured group (2.0% vs 0.0%), Fisher's Exact Test p = 0.04. Additionally, the matched cohort revealed a very low overall rate of capsular contracture (1.0%) for smooth implants. CONCLUSIONS Our data demonstrated non-significant differences for most major complication rates or revision surgery rates for smooth versus textured implants after matching. DTI breast reconstruction with smooth implants remains a safe and effective reconstructive option for select patients.

Abstract
INTRODUCTION This retrospective comparative study aimed to evaluate the effect of implant surface in two cohorts of consecutive patients who underwent revision surgery following capsular contracture (Baker III-IV) after primary breast augmentation with textured implants. METHODS All patients underwent the same surgical procedure (capsulectomy - pocket plane change - implant exchange) and the only difference was that two different types of implants were used during the implant exchange: textured(Group A - biocell) or nanotextured(Group B - silksurface). A comparative analysis was performed using the following parameters: patients' demographics, age, the time between the primary breast augmentation and the revision surgery, the surgical and follow-up outcomes; and the incidence, timing, and capsular contracture recurrence. RESULTS Eighty consecutive females were included, Group A(textured): age of 35(19-65) years and time between primary and secondary surgery of 59(6-209) months; and Group B(nanotextured): age of 39(26-58) years and time between primary and secondary surgery of 65(7-218) months. For both groups, at a mean follow-up of 25(21-36) months for Group A(textured), and at a mean follow-up of 24(21-34) months for Group B(nanotextured); capsular contracture reoccurred in 3 cases (7.5%), at 7, 10, and 14 months in Group A and in 3 cases (7,5%), at 9, 10, and 16 months in Group B, post revision surgery. Students' t-test demonstrated no statistically significant differences between the recurrences of the two implant surfaces (p-value>0.05). CONCLUSION In capsular contracture revision surgery, the type of implant surface (textured or nanotextured) does not appear to influence recurrence rates. Further studies are required to identify the clinical impact on the implant surface in long-term outcomes of capsular contracture breast surgery.

Abstract
Capsular contracture is the leading complication after surgery with breast implants. A lot of progress has been made investigating this complication over the years, and knowledge has been gained on this complication. Currently, the exact cause for capsular contracture is still unclear. It has been hypothesized that immunobiological factors (i.e., immunological and bacterial factors) and several risk factors play a central role in its development. In this paper, we give an overview of the known immunological factors that have been investigated in contracted and non-contracted capsules, as well as the role of bacterial formation around breast implants. We also report on risk factors that might increase the risk of capsular development. Lastly, it provides the latest research on this matter and discusses future perspectives as follow-up research is needed to unravel the pathogenic process leading to capsular contracture. This knowledge is of interest to establish medical therapies in order to prevent such side effects. Overall, capsular contracture seems to be a multifactorial condition consisting of several risk factors.

Abstract
BACKGROUND The Motiva Ergonomix™ Round SilkSurface (Establishment Labs Holdings Inc., Alajuela, Costa Rica) is the fifth generation of a silicone gel-filled breast implant that is commercially available in Korea. OBJECTIVES In this study, we describe 4-year interim results of the safety of augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface in Korean women. METHODS In the current multicenter, retrospective study, we performed a retrospective review of medical records of a total of 1314 patients who received augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface at our hospitals between September 1, 2016, and August 31, 2020. For safety assessment, we analyzed incidences of postoperative complications and Kaplan-Meier complication-free survival of the patients. RESULTS We included a total of 873 patients (1746 breasts, mean age = 32.18 ± 6.88 years) in the current study. There were a total of 111 cases (12.70%) of postoperative complications; these include 24 cases (2.70%) of early seroma, 18 cases (2.10%) of hematoma, 18 cases (2.10%) of capsular contracture, 17 cases (1.95%) of dissatisfaction with shape, 16 cases (1.83%) of dissatisfaction with size, 9 cases (1.03%) of asymmetry, 6 cases (0.70%) of infection and 3 cases (0.34%) of rippling. Moreover, time-to-events were estimated at 918.34 ± 36.22 days (95% CI 845.44-988.52). CONCLUSIONS Here, we describe 4-year interim results of the safety of augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface in Korean women in a non-manufacturer-sponsored study. But further large-scale, prospective, multicenter studies with a long period of follow-up are warranted to establish our results.

Implant malposition is one of the most common causes for revision after prosthetic breast reconstruction. There is a paucity of research on the incidence, etiology and risk factors for implant malposition in this setting. Methods Retrospective review of a single surgeon's prosthetic breast reconstructions was performed. Variables collected included age, BMI, radiation, chemotherapy, implant characteristics and malposition location (inferior or lateral). Binary logistic regression identified risk factors for malposition. Chi-square test assessed malposition rate as a function of implant volume to BMI subgroups. Results Of 836 breasts, 82 (9.8%) exhibited implant malposition. Risk factors for any malposition were older age (OR 1.05, 95% CI 1.02-1.07), BMI<25 (OR 1.64, 95% CI 1.00-2.70) and bilateral reconstruction (OR 13.41, 95% CI 8.50-21.16). Risk factors for inferior malposition were older age (OR 1.04, 95% CI 1.01-1.06), BMI<25 (OR 3.43, 95% CI 1.88-6.26) and bilateral reconstructions (OR 11.50, 95% CI 6.79-19.49), while risk factors for lateral malposition were only older age (OR 1.05, 95% CI 1.02-1.08) and bilateral reconstructions (OR 7.08, 95% CI 4.09-12.26). Post-mastectomy radiation was protective against lateral malposition (OR 0.30, 95% CI 0.10-0.88). Stratification by implant volume and BMI demonstrated patient subgroups with distinct patterns of malposition (incidence 0.0% versus 10.9%, P = 0.001). Conclusions This is the first study to identify risk factors for implant malposition after prosthetic breast reconstruction. Different risk factors contributed to malposition in different directions. The effect of implant size on malposition was mediated through BMI, highlighting the interplay of implant and patient characteristics with respect to malposition.

Abstract
BACKGROUND Capsular contracture following breast augmentation is prone to recurrence with conventional surgical therapy. Adding acellular dermal matrix improves results but significantly increases operating time and cost. This study tested a new treatment algorithm that uses acellular dermal matrix selectively to optimize success rates while minimizing its drawbacks. METHODS All patients surgically treated by the authors for Baker grade III/IV capsular contracture between 2007 and 2018 were included in this retrospective cohort study. Data were collected on patient, breast augmentation, capsular contracture, and surgical treatment characteristics, in addition to follow-up findings. Treatment success was defined as Baker grade II or better. RESULTS One hundred eighty patients underwent 217 surgical treatments for capsular contracture. Conventional treatment was used in 185 cases and acellular dermal matrix in 32. Twenty-six patients were treated for a second occurrence and four were treated for a third. The average follow-up was 2.4 years. Conventional treatment was successful in 72.5 percent of first occurrences, 62.5 percent of second occurrences, and 50.0 percent of third occurrences. Acellular dermal matrix was successful in 96.9 percent of cases. The odds of failure were increased by bilateral capsular contracture (3.9 times) and previous treatment failure (3.5 times). When acellular dermal matrix was used selectively for bilateral capsular contracture or in unilateral cases with a previous treatment failure, the overall treatment success rate improved to 85.6 percent compared with 64.2 percent when this algorithm was not followed (p < 0.001). CONCLUSION This study demonstrates that selective acellular dermal matrix use can increase success rate to over 85 percent in the overall treatment of capsular contracture, and to nearly 100 percent in individual cases.

Abstract
BACKGROUND Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emergent disease that threatens patients with texturized breast implants. Major concerns about the safety of these implants are leading to global changes to restrict the utilization of this product. The principal alternative is to perform breast augmentation utilizing smooth implants, given the lack of association with BIA-ALCL. The implications and costs of this intervention are unknown. OBJECTIVES The authors of this study determined the cost-effectiveness of smooth implants compared with texturized implants for breast augmentation surgery. METHODS A tree decision model was utilized to analyze the cost-effectiveness. Model input parameters were derived from published sources. The capsular contracture (CC) rate was calculated from a meta-analysis. Effectiveness measures were life years, avoided BIA-ALCL, avoided deaths, and avoided reoperations. A sensitivity analysis was performed to test the robustness of the model. RESULTS For avoided BIA-ALCL, the incremental cost was $18,562,003 for smooth implants over texturized implants. The incremental cost-effectiveness ratio was negative for life years, and avoided death and avoided reoperations were negative. The sensitivity analysis revealed that to avoid 1 case of BIA-ALCL, the utilization of smooth implants would be cost-effective for a risk of developing BIA-ALCL equal to or greater than 1:196, and there is a probability of CC with smooth implants equal to or less than 0.096. CONCLUSIONS The utilization of smooth implants to prevent BIA-ALCL is not cost-effective. Banning texturized implants to prevent BIA-ALCL may involve additional consequences, which should be considered in light of higher CC rates and more reoperations associated with smooth implants than with texturized implants.

Abstract
BACKGROUND Previous studies have reported decreased rates of capsular contracture associated with the use of textured surface breast implants placed in the subglandular plane during breast augmentation. However, since the publication of these studies, our understanding of the pathophysiology of capsular contracture, as well as the surgical techniques utilized to minimize bacterial contamination of the implant, have advanced considerably. OBJECTIVES The purpose of this study was to re-evaluate the relation between implant surface texturization and capsular contracture rates for breast implants placed in the subglandular plane during primary breast augmentation. METHODS Retrospective chart review was performed of all primary subglandular breast augmentation procedures involving the use of either smooth or textured round silicone gel implants, with or without simultaneous mastopexy. The primary outcome measures included clinically significant capsular contracture (Baker grade III/IV) and revision surgery for capsular contracture. RESULTS Between 2010 and 2017, 526 patients underwent primary subglandular breast augmentation with either smooth (n = 212) or textured (n = 314) round silicone gel implants; 248 patients underwent breast augmentation, whereas 278 underwent breast augmentation-mastopexy. Average follow-up was 756 days in the textured group and 461 days in the smooth group. Five cases of capsular contracture were observed in the textured group, and 7 cases of capsular contracture were observed in the smooth group (P = 0.20). CONCLUSIONS Smooth surface implants placed in the subglandular plane were not at a significantly increased risk of capsular contracture compared with textured surface implants. We suggest that adherence to a surgical technique focused on minimizing bacterial contamination of the implant is of greater clinical significance than implant surface characteristics when discussing capsular contracture.

Abstract
BACKGROUND The objective of this clinical review is to provide an overview of the use of silicone gel-filled breast implants placed in the sub-muscular position, with a focus on complication rates reported for both smooth and textured implants. Furthermore, our experience in this field is also reviewed. METHODS MEDLINE, EMBASE, Web of Science, Scopus, the Cochrane Central and Google Scholar databases were reviewed to identify the literature related to smooth breast implants. Each article was reviewed by two independent reviewers to ensure all relevant publications were identified. The literature search identified 98 applicable articles. Of these, just a few articles were found to have a therapeutic level of evidence. The reference lists in each relevant paper were screened manually to include relevant papers not found through the initial search. RESULTS Eight articles report the risk of capsular contracture when the breast implants were placed in the sub-muscular position. Six of these articles report a similar rate of capsular contracture in smooth and textured implants. Local complications such as wrinkling, late seroma and double capsules were found to be associated with the use of textured breast implants (4 articles). All articles concerning BIA-ALCL reported a total absence occurring in smooth breast implants. All cases have been associated with textured mammary prostheses. CONCLUSION With our expertise in the field and the results of this up-to-date literature review, it can be concluded that there are no significant advantages of using one type of implant surface over the other when placed in the sub-pectoral position. LEVEL OF EVIDENCE V This journal requires that authors assign a level of evidence to each article.

Breast Implant Surfaces and Their Impact on Current Practices: Where We Are Now and Where Are We Going? PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2466.

Abstract
Most commercially available breast implants feature some degree of elastomer surface modifications to increase surface roughness, in part because several clinical series have demonstrated positive outcomes from texturizing. However, the literature shows that textured implants support higher rates of bacterial growth, and there is a clear association between increased bacterial contamination and host response in vivo, such as capsular contracture. Furthermore, the infectious theory related to bacterial contamination has recently been described as a potential cause in the etiology of anaplastic large-cell lymphoma. Recent research has focused on the physiology of breast implant surfaces advances and how they interact with the body, creating new surface technologies which have the potential to affect all aspects of breast surgery. Understanding how surface properties affect inflammatory cell response will be essential in designing implants that can provide an esthetic solution while also minimizing long-term clinical complications. This special topic highlights the current knowledge on silicone implant surfaces, as well as innovations that have shaped and will continue to change the silicone breast implant industry in the future. It also provides an overview of the principal surfaces that exist and may find clinical applications in esthetic and reconstructive breast surgery. As additional advances emerge, objective tools will be required to evaluate the different surfaces available on the market, along with the long-term efficacy of new technologies.

Abstract
BACKGROUND With breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) now accepted as a unique (iatrogenic) subtype of ALCL directly associated with textured breast implants, we are now at a point where a sound epidemiologic profile and risk estimate are required. The aim of this article is to provide a comprehensive and up-to-date global review of the available epidemiologic data and literature relating to the incidence, risk, and prevalence of BIA-ALCL. METHODS All current literature relating to the epidemiology of BIA-ALCL was reviewed. Barriers relating to sound epidemiologic study were identified, and trends relating to geographical distribution, prevalence of breast implants, and implant characteristics were analyzed. RESULTS Significant barriers exist to the accurate estimate of both the number of women with implants (denominator) and the number of cases of BIA-ALCL (numerator), including poor registries, underreporting, lack of awareness, cosmetic tourism, and fear of litigation. The incidence and risk of BIA-ALCL have increased dramatically from initial reports of 1 per million to current estimates of 1/2,832, and is largely dependant on the "population" (implant type and characteristics) examined and increased awareness of the disease. CONCLUSIONS Although many barriers stand in the way of calculating accurate estimates of the incidence and risk of developing BIA-ALCL, steady progress, international registries, and collegiality between research teams are for the first time allowing early estimates. Most striking is the exponential rise in incidence over the last decade, which can largely be explained by the increasingly specific implant subtypes examined-driven by our understanding of the pathologic mechanism of the disease. High-textured high-surface area implants (grade 4 surface) carry the highest risk of BIA-ALCL (1/2,832).

Abstract
Breast implantation either for cosmetic or reconstructive e purposes is one of the most common procedures performed in plastic surgery. Biofilm infection is hypothesised to be involved in the development of both capsular contracture and anaplastic large cell lymphoma (ALCL). Capsular contracture is one of the principal reasons for breast revision surgery and is characterised by the tightening and hardening of the capsule surrounding the implant, and ALCL is an indolent lymphoma found only in women with textured implants. We describe the types of breast implants available with regard to their surface characteristics of surface area and roughness and how this might contribute to capsular contracture and/or biofilm formation. The pathogenesis of capsular contracture is thought to be due to biofilm formation on the implant, which results in on-going inflammation. We describe the current research into breast implant associated ALCL and how implant properties may affect its pathogenesis, with ALCL only occurring in women with textured implants.

Abstract
BACKGROUND Capsular contracture is the most frequent complication in breast augmentation or reconstruction with breast implants. The exact mechanism for this complication is not completely understood. Yet, it is most likely to be a multifactorial condition. Several patient-, surgery-, and implant-specific risk factors have been related to cause capsular contracture. This review aims to provide a clear overview of all risk factors for capsular contracture. METHODS A systematic literature review was performed focusing on patient-, surgery-, and/or implant-related factors related to capsular contracture in breast implants. PubMed, Embase, and Wiley/Cochrane Library databases were searched for relevant articles published from inception up to October 20, 2016. The included studies were assessed for the following main variables: study characteristics, patient characteristics, indication for surgery, type of surgery, implant characteristics, and other characteristics. RESULTS Data on the risk factors for the development of capsular contracture were retrieved from 40 studies. A presumptive increased risk in the development of capsular contracture is shown for the following variables: longer duration of follow-up, breast reconstructive surgery in patients with a history of breast cancer, subglandular implant placement, postoperative hematoma, and a textured implant surface. There is little, weak, or no evidence for the association of other factors with capsular contracture. This review also shows a large heterogeneity between studies and within the definition of capsular contracture. CONCLUSION This review provides an overview of the relationship between patient-, surgery-, and implant-specific risk factors in the development of capsular contracture.

Abstract
Introduction: Although strides have been made to improve breast augmentation surgery, they have focused on the use of single implant devices, necessitating adjustments to the type of operation performed and implants used. And although some breast types obtain excellent results, many others are less than optimal. By developing a thin synthetic expanded polytetrafluoroethylene device, the Pocket Protector, that lines the breast pocket by integrating with the body without a capsule formation, smooth-surfaced gel (or saline) implants can remain soft and provide improved augmentation mammoplasty results. Even patients with Baker class III and IV breasts refractory to all types of revisional surgery can achieve soft, natural breasts after revision with the Pocket Protector. Materials and Methods: Augmentation mammoplasty and revision mammoplasty, often with capsulectomy, with the Pocket Protector was performed on 38 patients with smooth gel or saline implants. Since the initial prototype in April 1995, data have been collected with each patient to evaluate the efficacy of this device. Results: Patients involved in the current study have yielded soft, natural-feeling breasts in the normal anatomic position. Two patients who experienced a flu syndrome in the immediate postoperative period developed refractory seromas necessitating removal of the expanded polytetrafluoroethylene. Both cases have subsequently been successfully revised with Pocket Protectors and smooth-gel implants. Three patients with very thin tissues experienced rippling in spite of using smooth-gel implants. Discussion: The net result yields a soft, ripple-free (or near ripple-free) breast. Additionally, gel implants inside the Pocket Protector are potentially shielded from the body, should the implants rupture. Implants are easily exchangeable if necessary without need for capsulectomy or capsulotomy. The Pocket Protector may also represent an implant device appropriate to treat breasts refractory to traditionally attempted augmentations, such as subcutaneous mastectomy. Although the first case performed in April 1995 has remained successful, most of the experience has been gathered over the past year. This preliminary paper presents the experience with the past 38 cases.

Abstract
Capsular contracture is a common sequelae of implant-based breast augmentation. Despite its prevalence, the etiology of capsular contracture remains controversial. Numerous studies have identified microbial biofilms on various implantable materials, including breast implants. Furthermore, biofilms have been implicated in subclinical infections associated with other surgical implants. In this review, we discuss microbial biofilms as a potential etiology of capsular contracture. The review also outlines the key diagnostic modalities available to identify the possible infectious agents found in biofilm, as well as available preventative and treatment measures.

Abstract
Purpose Capsular contracture is the most frequent long-term complication after implant-based breast reconstruction or augmentation. The aim of this study was to evaluate the impact of implant surface properties on fibrotic capsule formation in an animal model. Materials and Methods Twenty-four rats received 1 scaled down silicone implant each; 12 of the rats received implants with textured surfaces, and the other 12 received implants with smooth surfaces. After 60 and 120 days, rats in each group underwent 7-Tesla Magnetic Resonance Imaging (MRI) and high-resolution ultrasound (HR-US), and specimens of the capsules were acquired and used to measure capsule thickness through histology, collagen density through picro sirius red staining, and analyses of expression of pro-fibrotic and inflammatory genes (Collagen1-4, TGFb1, TGFb3, Smad3, IL4, IL10, IL13, CD68) through qRT-PCR. Furthermore, MRI data were processed to obtain capsule volume and implant surface area. Results On day 60, histology and HR-US showed that fibrotic capsules were significantly thicker in the textured implant group with respect to the smooth implant group (p<0.05). However, this difference did not persist on day 120 (p=0.56). Capsule thickness decreased significantly over the study period in both smooth and textured implant groups (p<0.05). Thickness measurements were substantiated by MRI analysis and volumes changed accordingly. Implant surface area did not vary between study dates, but it was different between implant types. On day 60, the density of collagen in the fibrotic capsules was significantly lower in the textured implant group with respect to the smooth group (p<0.05), but again this difference did not persist on day 120 (p=0.67). Collagen 1 and CD68 were respectively over- and under expressed in the textured implant group on day 60. Significant differences in the expression of other genes were not observed. Conclusion Silicone implants with textured surfaces led to temporarily thicker but less dense fibrotic capsules compared with smooth surfaces. 7-Tesla MRI and HR-US are capable for non-invasive in-vivo assessment of capsular fibrosis in an animal model and can provide unique insights into the fibrotic process by 3D reconstruction and surface area measurement.

Histological characterization of human breast implant capsules. Aesthetic Plast Surg 2015; 39:306-15.

Abstract
Background This study investigated the relationships between histomorphological aspects of breast capsules, including capsule thickness, collagen fiber alignment, the presence of α-smooth muscle actin (α-SMA)–positive myofibroblasts, and clinical observations of capsular contracture. Methods Breast capsule samples were collected at the time of implant removal in patients undergoing breast implant replacement or revision surgery. Capsular contracture was scored preoperatively using the Baker scale. Histological analysis included hematoxylin and eosin staining, quantitative analysis of capsule thickness, collagen fiber alignment, and immunohistochemical evaluation for α-SMA and CD68. Results Forty-nine samples were harvested from 41 patients. A large variation in histomorphology was observed between samples, including differences in cellularity, fiber density and organization, and overall structure. Baker I capsules were significantly thinner than Baker II, III, and IV capsules. Capsule thickness positively correlated with implantation time for all capsules and for contracted capsules (Baker III and IV). Contracted capsules had significantly greater collagen fiber alignment and α-SMA–positive immunoreactivity than uncontracted capsules (Baker I and II). Capsules from textured implants had significantly less α-SMA–positive immunoreactivity than capsules from smooth implants. Conclusion The histomorphological diversity observed between the breast capsules highlights the challenges of identifying mechanistic trends in capsular contracture. Our findings support the role of increasing capsule thickness and collagen fiber alignment, and the presence of contractile myofibroblasts in the development of contracture. These changes in capsule structure may be directly related to palpation stiffness considered in the Baker score. Approaches to disrupt these processes may aid in decreasing capsular contracture rates. Level of Evidence III This journal requires that authors assign a level of evidence to each article.

Abstract
Background Silicone breast implants have long been used for breast augmentation and reconstruction. During this time, these medical devices have gone through a number of modifications to improve their safety, quality, and clinical outcome performance. Objectives The authors conducted a 10-year study to determine the safety and effectiveness of Natrelle 410 silicone breast implants. Methods This prospective, multicenter study enrolled 941 subjects who were undergoing either augmentation, augmentation revision, reconstruction, or reconstruction revision. Data on complications, reoperations, explantations, and subject satisfaction were collected at annual clinic visits, and one-third of subjects underwent biennial magnetic resonance imaging (MRI) to screen for implant rupture. The authors used the Kaplan-Meier estimator to calculate risk rates for local complications, reoperations, and explantations. Results Capsular contracture rates increased approximately 1% per year from the previously reported 6-year rates. The rates were significantly lower than those from the Natrelle round gel core study. The overall rate of confirmed ruptured implants in subjects who underwent MRI was 5.7%. Eleven late seromas were reported. The most common reason for explantation was a subject requesting a size or style change. Satisfaction rates remained high through 10 years, with most subjects saying they were somewhat or definitely satisfied with their implants. Conclusions This 10-year prospective trial demonstrated the long-term safety and effectiveness of Natrelle 410 anatomical form-stable implants. The complication rates were low and the satisfaction rates were high. Level of Evidence: 1

Abstract
Background: Allergan’s Natrelle round silicone-filled breast implants were approved by the U.S. Food and Drug Administration in 2006 based on interim results from the Core Study; final 10-year study results are now available. Methods: Seven hundred fifteen subjects were implanted with smooth and Biocell textured Natrelle round silicone implants and attended clinic visits at 0 to 4 weeks, 6 months, 1 year, and annually through 10 years. Approximately one-third of subjects underwent magnetic resonance imaging at years 1, 3, 5, 7, and 9 to assess rupture. Results: Complication rates showed modest increases over the previously published 6-year rates. The Kaplan-Meier capsular contracture rate was 18.9 percent for augmentation, 28.7 percent for revision-augmentation, and 24.6 percent for reconstruction. Among augmentation subjects, capsular contracture was significantly lower (p = 0.023) for submuscular (15.7 percent) versus subglandular (26.3 percent) placement. The overall rupture rate in the magnetic resonance imaging cohort was 13.0 percent for subjects and 7.7 percent for implants. By the end of the study, 81.8 percent of augmentation subjects still had an original implant in place. Using a five-point scale, 94.2 percent of augmentation, 83.8 percent of revision-augmentation, and 90.7 percent of reconstruction subjects reported being satisfied or definitely satisfied with their implants. Significant improvement over baseline was also seen in overall breast satisfaction and satisfaction with breast size, shape, feel, and how well they matched. Conclusion: The 10-year data from the Natrelle Core Study, which can guide surgeons and patients in decision-making, demonstrate safety and high levels of patient satisfaction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Abstract
Capsular contracture is one of the major complications of augmentation mammaplasty. A review of 638 augmented breasts in 319 consecutive patients who underwent primary augmentation, with an average follow-up of 17.2 months and without a single case of capsular contracture of any degree to date, is presented, along with a discussion of the surgical technique and complications, and an analysis of measures used to prevent capsular contraction. Each patient received a pair of smooth saline-filled implants (Mentor, USA) placed in the submuscular space through an inframammary incision. In all operated breasts, many of the known measures commonly used for capsular contracture prevention were implemented. As well, a dependent drain was used as the final hemostatic step to prevent blood accumulation in the pocket. Leaving a dependent drain in the dissected pocket overnight, as one of the sequence of measures aimed at eliminating blood accumulation, is believed to be a contributing factor in capsular contracture prevention.

Abstract
BACKGROUND Capsular contracture remains the most common complication following breast augmentation surgery, and evidence suggests that bacterial biofilm on the implant surface is responsible. The authors investigated whether the interaction of bacterial biofilm with implants independently determines progression to capsule formation. They also studied the rate of bacterial growth and adhesion to implants. METHODS Sixteen adult female pigs had 121 breast implants inserted. Sixty-six implants-23 smooth and 43 textured-were inoculated with a human strain of Staphylococcus epidermidis and received no other treatment. After an average period of 19 weeks, Baker grading was performed and implants were retrieved. For the in vitro study, samples underwent both quantitative bacterial analysis and imaging using confocal laser scanning and scanning electron microscopy. RESULTS At explantation, there was no significant difference (p = 1.0) in the presence of capsular contracture (Baker grade III and IV) between smooth (83 percent) and textured implants (84 percent). Biofilm was confirmed on 60 of the 66 capsules. Capsules from smooth and textured implants had the same number of infecting bacteria (textured: 3.01 × 10 bacteria/g; smooth: 3.00 × 10 bacteria/g). In vitro, the surface of textured implants showed 11-, 43-, and 72-fold more bacteria at 2, 6, and 24 hours, respectively, compared with smooth implants (p < 0.001). These findings were confirmed by imaging analysis. CONCLUSIONS These results show that textured implants develop a significantly higher load of bacterial biofilm in comparison with smooth implants. Furthermore, in vivo, once a threshold of biofilm forms on either smooth or textured implant surfaces, there seems to be an equal propensity to progress to capsular contracture.

Abstract
With increasing number of patients with silicone implants for breast augmentation or reconstruction we are confronted with more and more cases of capsular contracture. Not every case is resolved by resection of the capsule and exchange of implants. Many patients rather bear the consequences of severe fibrosis than to have their implants removed. The one stage procedure of implant removal and lipofilling proved to be highly efficient with good to excellent results and high patient satisfaction. Between January 2008 and October 2012 a total of 64 patients (124 breasts) with capsular fibrosis Baker III to IV were treated with autologous fat grafts collected with the body-jet® by water-assisted liposuction (“BEAULI Method”). Magnetic resonance imaging (MRI) of the breasts was performed in 5 patients preoperatively and 6 month postoperatively, a clinical examination and photo documentation of all patients was done on day 1 and after 4 weeks, 12 weeks and 6 months postoperatively. The procedure included implant removal and lipofilling of the subcutaneous and intramuscular space in a single procedure by means of the BEAULI Method. The average gross amount of grafted fat was 260 ml. The average drainage time was one day. The shape of the breast changed to a more natural and ptotic form. Negative side effects like oily cysts or infections were not observed. The time of the overall procedure including liposuction was 70±15 min. Reoccurring capsular contracture is one of the hazards in plastic surgery. Until now the treatment of choice after more than two failed implant changes combined with resection of the capsule is usually the final removal of implants with or without possible additional autologous tissue transfer (microvascular flaps). We could add a relatively simple and efficient procedure to resolve and improve those cases by autologous fat transfer using water-assisted liposuction and the BEAULI Method.

Abstract
BACKGROUND Overt infection and biofilm formation resulting from breast augmentation are rare but serious problems that can lead to contracture and a need for revision surgery. The Keller Funnel is a medical device composed of a rip-stop nylon sleeve with a hydrophilic inner coating. One claim of the funnel is that it facilitates a "no touch" technique, thereby limiting contamination. To date, there are no data to support this claim. OBJECTIVES The authors evaluate skin and breast parenchyma contamination with standard implantation techniques and the Keller funnel. METHODS Insertion techniques were tested in two fresh cadavers. Smooth, round, moderate-plus silicone gel implants were placed for each experiment. To quantify the amount of skin contamination, a 2% w/v fluorescein paste was painted onto the cadaver thorax. After implantation, the implants were soaked in 250 mL of sterile water, and the fluorescence emission of the resulting solution was measured with an ultraviolet-visible spectrophotometer. To qualify the potential contamination from breast parenchyma, the cadaver breast tissue was swabbed with methicillin-sensitive Staphylococcus aureus, and the implant surfaces were cultured postimplantation. RESULTS The funnel resulted in a 27-fold decrease in skin contact for all smooth gel implants (P = .00059). The amount of skin contact and potential contamination increased incrementally with increasing implant volume when either the funnel or digital implantation techniques were used. Bacterial contamination from breast parenchyma was two times more likely with the standard digital insertion technique (P = .06). CONCLUSIONS The Keller funnel appears to significantly reduce the amount of skin contact and potential parenchyma contamination.

Abstract
Breast augmentation is one of the most frequently performed aesthetic surgery procedures. In the United States, it is the second most commonly performed aesthetic surgery procedure among women, according to the American Society of Aesthetic Plastic Surgery statistics. Different choices available to the surgeon deal with the pocket plane, the skin incisions, and the type of implant. This report describes the results from a retrospective review of the authors' experience with the "triple-plane technique" and its different indications according to breast types. Findings have shown that this technique is suitable for many different types, shapes, and sizes of breasts; that it offers very good and natural results; and particularly, that these results last over time.
