Abstract
BACKGROUND Broad evidence supports the use of antiseptic pocket rinse in breast implant surgery to minimize the risk of capsular contracture or other complications. However, there is limited consensus or standardization of antiseptic rinse in practice. OBJECTIVES In this preliminary study, we sought to determine contemporary trends in antiseptic rinse use in primary breast implant surgery based on Australian Breast Device Registry (ABDR) data, and whether these trends align with the suggestions of the 14-point plan.2 This further served as a feasibility study for subsequent comparison of antiseptic rinse effects on clinical outcomes. METHODS Institutional ethics approval was obtained and national ABDR data for primary breast implant surgery from 2015-2020 was analysed for the use, and type, of antiseptic rinse. The surgeon-reported data was homogenized for terminology and categorized into major trends, and the literature reviewed. RESULTS We analysed data for 37,143 patients, totalling 73,935 primary implants. Antiseptic rinse included Povidone-Iodine (PVP-I) in 35,859 (48.5%), no antiseptic use in 24,216 (32.8%), other concentrations of PVP-I in 4,200 (5.7%), and 'Betadine® triple antibiotic'1 in 1,831 implants (2.5%). Multiple other antiseptic permutations were noted in 7,004 implants (9.5%). CONCLUSIONS The majority (56.7%) of Australian practitioners utilise previously-described antiseptic pocket irrigation solutions which align with the 14-point plan. A third (32.8%), however, do not record any antiseptic pocket irrigation use. These findings will permit a subsequent (ongoing) study of outcomes comparing PVP-I to no antiseptic pocket rinse that will likely constitute the largest study of its kind.

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
AbstractAlthough capsular contracture represents one of the most important complications after breast augmentation, local inflammation and fibrosis can lead, in very rare cases, to capsular calcification, an often-forgotten radiological sign of capsular contracture. In this article, the authors present a clinical case of breast implant calcification in an 81-year-old patient. Although this complication has been rarely described, the literature was reviewed to clarify the role of the local microenvironment in capsular contracture and calcification. At present, capsular contracture patients are classified using the conventional Baker score and the histological Wilflingseder classification. As it was not possible to consider capsular calcification when classifying our patient using the traditional scores, the authors propose an updated version of the current scale.

Abstract
BACKGROUND In advanced breast cancer, radiotherapy is recommended as adjuvant therapy following breast reconstructive surgery. This inevitably led to growing concerns over possible complications of radiotherapy on implants. In this experimental animal study, we investigated the utility of acellular dermal matrix (ADM) wraps around implants as preventive management for radiotherapy complications. METHODS Black mice (C57NL6; n = 32) were assigned to groups that either received radiation or did not: groups A and B underwent surgery using implants without radiotherapy; while groups C and D underwent surgery using implants with radiotherapy for one and three months, respectively. The hemispheric silicone implants with an 0.8-cm-diameter were inserted on the left back of each mouse, and implants wrapped by ADM were inserted on the right back. The Clinic 23EX LINAC model was used for irradiation at 10 Gy. The samples were evaluated by gross assessment, histological analysis, immunohistochemical analysis, and the Western blotting test. RESULTS The H&E staining analysis showed that membrane thickness is smallest in group A, followed by groups C, D, and B. In a Masson trichrome histological analysis, collagen fibers became less dense and more widespread over time in the groups that received an ADM. Immunohistochemistry findings were similarly constant. However, the expression of TGF-β1 was increased in the irradiated groups, whereas it was decreased in the non-irradiated groups as observed over time. CONCLUSIONS Radiotherapy was shown to increase risk factors for capsular contracture, including inflammatory response, pseudoepithelium, thinning of membrane, and TGF-β1 expression over time; however, the accompanying framework using an ADM as a barrier between implant and tissue was shown to be effective in alleviating these risks.

Abstract
BACKGROUND Capsular contracture (CC) is a significant complication and major reason for revision in breast augmentation. Many studies indicate that most bacteria found in contracted capsules originate from the skin, especially that of the nipple-areolar complex (NAC). To prevent implant contamination, protocols without a periareolar incision have been proposed and have become a limitation for breast augmentation. We sought to propose a strategy of proper skin management for periareolar incisions to prevent implant contamination and biofilm-related CC. METHODS The analyses in this study are based on data collected from February 2017 to July 2020. A total of 129 patients were included, and they were randomized into two groups. The control group was subjected to no skin treatment before the surgery, and the treatment group underwent preoperative cleaning and disinfection of the NAC. We collected bacteriologic swabs used to rub the skin of the NAC and chest after draping and suturing from the control and treatment groups. We assessed the potential risk of detecting bacteria or fungi in the swabs, and we analyzed the data. The relationship between the positive culture rate and complication rate indicated the effectiveness of our strategy. RESULTS Initially, 774 swabs were obtained. In the control group, 6 swabs tested positive for pathogens, including 2 NAC swabs positive for Staphylococcus epidermidis (S. epidermidis) after draping and 3 and 1 NAC swabs positive for S. epidermidis and Staphylococcus aureus (S. aureus) after suturing, respectively. All the other samples in the control and treatment groups were negative for bacteria or fungi. All patients had at least 16 months of follow-up. No CC (Baker grades II-IV) was recorded during the follow-up, and the treatment group experienced a better outcome associated with a lower rate of minor complications. CONCLUSIONS Proper preoperative skin management helps keep the field pristine and potentially prevents implant contamination and even biofilm-related CC. With this strategy, breast augmentation using a periareolar incision or any other approach, even other surgery, could be a safe procedure.

Abstract
Subclinical bacterial infections (biofilms) are strongly implicated in breast augmentation failure due to capsular contracture, and while these infections are generally ascribed to common skin commensals, this remains largely unsubstantiated through robust cultivation independent analyses. To determine capsule biofilm microbial community compositions, we employed amplicon sequencing of the 16S rRNA gene using DNA extracted from breast implant capsule samples. These cultivation independent analyses revealed that capsule associated biofilms are more diverse than canonical single-species infections, but have relatively low diversity (~ <100 species) compared to many host-associated microbial communities. In addition to taxa commonly associated with capsular contracture, the biofilms analyzed comprised a number of taxa that escaped detection in cultivation-dependent work. We have also isolated several key taxa identified through the culture-independent analyses. Together our analyses reveal that capsule biofilms are more diverse than cultivation studies suggest and can be heterogeneous within an individual capsule, between breasts of the same patient, across similar implant types, and over a range in severity of contracture. The complex nature of these communities requires further study across a broader suite of patients in addition to higher resolution analyses including metagenomics to better assess the fundamental role of microorganisms in capsular contracture.

Abstract
ABSTRACT Breast augmentation is one of the most commonly performed cosmetic surgical procedures in the United States. Modern breast augmentation has evolved with the development of various implant options, as well as surgical techniques. To achieve ideal result, it is important for the surgeon to develop a systematic approach to evaluate each patient. The 5 key steps in determining the best surgical plan include: (1) assess the need for concurrent mastopexy, (2) implant selection, (3) pocket plane, (4) inframammary fold position, (5) choice of incision. The purpose of this review is to discuss the principles behind each of these key concepts and how to utilize them in achieving the optimal outcome in breast augmentation.

Abstract
BACKGROUND Aesthetic and reconstructive implant-based breast surgeries are some of the most frequently performed procedures by plastic surgeons. As such, prevention of implant infection is of high importance. However, there remains no criterion-standard protocol for irrigation of the breast pocket. This review focuses on current irrigation practices in implant-based breast surgery. METHODS Four databases were used to search for all studies, including randomized controlled trials, retrospective cohort, and prospective cohort, containing original data related to the outcomes investigated in this study. Search terms included "breast," "irrigation," and "infection" in different combinations to isolate studies that focused on irrigation methods in both reconstructive and augmentation surgeries. Our selection criteria specifically concentrated on those studies that explicitly related irrigation procedures to rates of clinical infection and/or capsular contracture. Each was compiled into a table in chronological order to make comparisons between the differing irrigation methods. RESULTS Our search returned 239 full-text articles eligible for our review. Two independent screeners identified 9 studies that met the inclusion criteria. This included 1 prospective study and 8 retrospective studies. Two studies reported the use of chlorhexidine gluconate irrigation resulting in protection from clinical infection. Two studies investigated the role of triple antibiotic solution (TAS) either alone or combined with something else on risk of infection, and 3 reported TAS use on rates of capsular contracture. Two additional studies investigated the role of single antibiotic irrigation, concluding that some antibiotic regimen for irrigation may be sufficient in the breast pocket. Interestingly, one study noted the potential use of povidone-iodine (Betadine) as a method of irrigation. CONCLUSIONS These data suggest that chlorhexidine gluconate, Betadine, and TAS irrigation of the breast pocket can provide protection against infection and implant loss in both reconstruction and augmentation surgeries.

Abstract
Although silicone implants are the most popular choice around the world for breast augmentation, reconstruction, and revision, due to the poor antibacterial properties and limited biocompatibility of silicone rubber (SR), one of the major complications, capsule contracture, is a lingering problem. To overcome the two main shortcomings, a dual ion implantation technique was applied to modify the surface of SR with the basic skeleton element of organic matter, carbon (C) and the broad-spectrum bactericide, silver (Ag). We present surface characterization, toxicological effects, and evaluation of the mechanical, antibacterial and biocompatible properties of C and Ag co-implanted SR (C/Ag-SRs). After ion implantation, surface roughness and tensile strength of these new materials increased. Biotoxicity was fully assessed by in vitro experiments on human fibroblasts and in vivo experiments on rats, showing that the low-Ag groups met safety standards. Both the anti-bacterial adhesion and bactericidal abilities of C/Ag-SRs were superior to those of SR, which had few antibacterial activities, especially against Staphylococcus epidermidis. With respect to biocompatibility, the adhesion of fibroblasts was promoted, while their proliferation was moderately inhibited on ion-implanted surfaces. After subcutaneous implantation in rats for 7, 30, 90 and 180 d, the capsular thickness around C/Ag-SRs was significantly lower than that around the SR. Additionally, there was no difference in the inflammatory reaction after 7 d of retention in vivo between C/Ag-SRs and SR. The results demonstrate that C/Ag-SRs are desirable shell materials for breast implants.

Abstract
In order to reexamine the possible association between bacterial presence and capsular contracture, 55 silicone devices (mammary implants or tissue expanders) were cultured at the time of their removal from 40 patients. Special culture techniques were used in an attempt to recover bacteria adhering to the smooth-surfaced implant and encased in glycocalyx biofilm. Bacteria were detected on 56% (15 of 27) of implants surrounded by contracted capsules and on 18% (5 of 28) of those without capsular contracture (p < 0.05). Only three implants tested positive using routine plating techniques. The predominant isolate was Staphylococcus epidermidis. The concept that capsular contracture is associated with subclinical infection of silicone implants is supported by this study. With changes in the microbiological technique, bacterial recovery and growth occurs at a frequency greater than previously thought.

Abstract
BACKGROUND The aetiology of capsular contracture around breast implants remains unclear. The leading theory is that a subclinical infection around the implant plays a role in the development of capsular contractions. Several studies found associations between the presence of bacteria and the occurrence of capsular contraction. However, it is unclear whether detected bacteria originate from the breast capsule, breast glandular tissue or skin contamination. Moreover, this has never been investigated with molecular techniques. The aim of this study was to assess the bacterial microbiota on breast capsules, glandular tissue and skin using a highly sensitive PCR assay. MATERIALS AND METHODS Fifty breast capsules were collected during implant removal or replacement. Ten specimens of glandular breast tissue and breast skin were collected in females who were undergoing reduction mammoplasty. A sample specimen (4 mm) was sterilely obtained from all tissues. All specimens were analysed by IS-pro, a 16S-23S interspace region-based PCR assay. RESULTS Low numbers of Staphylococcus spp. (four species in four capsules) were found on breast capsules. There was no difference in bacterial presence between normal and contracted capsules. The skin of the breast-harboured Streptococcus spp. and Staphylococcus spp. while the glandular tissue was sterile. CONCLUSION The low numbers of bacteria found on the capsules are most likely caused by contamination during capsule removal. More and larger studies are needed to investigate the bacterial presence on breast capsules using a PCR assay. This is the first study in which breast capsules have been studied using a highly sensitive PCR assay.

Abstract
BACKGROUND Capsular contracture (CC) has remained an unresolved issue throughout history. Strong evidence focuses on bacterial biofilm as its main source. A literature review revealed that more than 90% of bacteria found in capsules and implants removed from patients with Baker grade III-IV CC belong to the resident skin microbiome (Staphylococcus epidermidis, predominant microorganism). The use of an adequate preoperative skin antiseptic may be a critical step to minimize implant contamination and help prevent biofilm-related CC. OBJECTIVES The authors sought to compare the effect of 2 different antiseptic skin preparations: povidone-iodine (PVP-I) vs chlorhexidine gluconate (CHG) on CC proportions after primary breast augmentation through a periareolar approach. METHODS In June of 2014, The Society for Healthcare Epidemiology of America proposed to use CHG for preoperative skin preparation in the absence of alcohol-containing antiseptic agents as strategy to prevent surgical site infection. The clinical safety committee of a surgical center in Colombia decided to change PVP-I to CHG for surgical site preparation thereafter. The medical records of 63 patients who underwent to primary breast augmentation through a periareolar approach during 2014 were reviewed. In the first 6 months PVP-I was used in 32 patients, and later CHG was employed in 31 patients. RESULTS Pearson's chi-squared test to compare CC proportions between subgroups showed a statistically significant difference. The CC proportion was higher for patients who had antisepsis with PVP-I. CC was absent when CHG was employed. CONCLUSIONS CHG as preoperative skin antiseptic for primary breast augmentation surgery was more effective than PVP-I to help prevent biofilm-related CC.

Abstract
Background Implant-related deformities in aesthetic rhinoplasty are a major problem for rhinoplasty surgeons. Capsular contracture is believed to be the pathological cause of delayed contour deformities, comparable to breast implant-related contracture. This study investigated the prevalence of bacterial biofilms and other epidemiological factors related to capsular contracture in cases of silicone augmentation rhinoplasty. Methods Thirty-three patients who underwent corrective rhinoplasty due to a delayed contour deformity or aesthetic revision after implant rhinoplasty were studied from December 2014 to December 2016. All recruited patients received surgical correction by the authors. The patients were categorized by clinical severity into four grades. Demographic data and related confounding factors were recorded. Samples of capsular tissue and silicone removed from each patient were analyzed for the presence of a biofilm by ultrasonication with bacterial culture and scanning electron microscopy. Results Thirty-three paired samples of capsular tissue and silicone implants from the study group were analyzed. Biofilms were detected in one of 10 subjects (10%) with grade 1 contracture, two of four (50%) with grade 2 contracture, 10 of 14 (71.40%) with grade 3 contracture, and four of five (80%) with grade 4 contracture (P<0.05). The organisms found were Staphylococcus epidermidis (47.10%), coagulase-negative staphylococci (35.30%), and Staphylococcus aureus (17.60%). Conclusions As with breast implant-related capsular contracture, silicone nasal augmentation deformities likely result from bacterial biofilms. We demonstrated the prevalence of biofilms in patients with various degrees of contracture. Implant type and operative technique seemed to have only vague correlations with biofilm presence.

Abstract
BACKGROUND Breast reconstruction with implants can be complicated by symptomatic capsular contracture, especially after radiotherapy. A phase I, nonrandomized clinical trial demonstrated improvement in capsular contracture and avoidance of revision surgery with low-level laser therapy. This phase II, double-blind, randomized controlled trial assessed the efficacy of low-level laser for treating capsular contracture in women with breast reconstruction following mastectomy for breast cancer. METHODS Participants had completed their definitive implant-based reconstruction a minimum of 6 months previously and were randomized to weekly treatments over 6 weeks with either an active or inactive low-level laser handpiece (Riancorp LTU-904). Pain, tightness, arm movement, and appearance were assessed by patient questionnaires. Breast symmetry, shape, naturalness, softness, and grade of contracture were assessed by clinician reports. Participants were assessed at 1 and 6 months after completion of the treatments. RESULTS A total of 42 patients (intervention arm, n = 20; placebo, n = 22) were assessed in the trial. Thirty-two had postmastectomy radiotherapy. There was no significant difference in the change in any patient-reported outcomes or clinician-reported outcomes of breast symmetry, shape, or naturalness for the two groups. There was a significantly greater improvement in clinician-reported breast softness (p < 0.05) and degree of contracture (p < 0.05) in the placebo group at both 1- and 6-month follow-up. CONCLUSION Low-level laser is not an effective therapy for breast implant capsular contracture in reconstruction patients. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, I.

The A, B and C's of Silicone Breast Implants: Anaplastic Large Cell Lymphoma, Biofilm and Capsular Contracture. MATERIALS 2018; 11:ma11122393. [PMID: 30486500 PMCID: PMC6316940 DOI: 10.3390/ma11122393] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Revised: 11/19/2018] [Accepted: 11/26/2018] [Indexed: 02/08/2023]
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.

Effect of Keller Funnel on the Rate of Capsular Contracture in Periareolar Breast Augmentation. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2018; 6:e1834. [PMID: 30276059 PMCID: PMC6157951 DOI: 10.1097/gox.0000000000001834] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Accepted: 04/20/2018] [Indexed: 11/26/2022]
Abstract
Background Capsular contracture is 1 of the most common complications after breast implant surgery and is a major indication for reoperation. Capsular contracture is believed to be a multifactorial process that is affected by implant texture, incision type, and ultimately pocket contamination. This contamination causes a biofilm that leads to capsular contracture. The intraoperative use of a Keller funnel is a mechanical way to decrease the implant's contact with the skin and ducts, reducing bacterial contamination that can cause these biofilms. For this reason, periareolar breast augmentation has been less popular among surgeons. The purpose of this study was to examine if there was a significant difference between the rates of capsular contracture in patients having periareolar breast augmentations with the use of a Keller funnel for insertion and those having periareolar breast augmentations without Funnel use. Methods This level 3 retrospective study followed 2 groups of patients, the first having periareolar breast augmentations without the use of a funnel for insertion (group A; patients n = 15; implants n = 30) and the second having periareolar breast augmentations with the use of a funnel for insertion (group B; patients n = 151; implants n = 300). Results The rate of capsular contracture in group A was found to be 10% compared with a rate of capsular contracture of 1.3% for patients in group B, an 87% reduction (P = 0.0019). Conclusions According to the results found in this study, the rate of capsular contracture in patients having periareolar breast augmentations after insertion with a Keller funnel was statistically significantly lower than the rate in patients having implants inserted without the assistance of a funnel, making the device useful in reducing the occurrence of postoperative capsular contracture.

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
BACKGROUND The incidence of infection following breast implant reconstruction remains high at the level of 24%. Surgical site irrigation is commonly used for its prevention. However, the lack of evidence-based guidelines for antibiotic prophylaxis in breast implant surgery necessitates research for optimal irrigation technique. OBJECTIVES composition and exposure time of irrigation solution for surgical site infection (SSI) prophylaxis using an in vitro model of a surgical site. METHODS The study design was an in vitro model to assess antibiotic irrigation of a surgical site. Strains of Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Group A Streptococcus, and Pseudomonas aeruginosa were seeded on blood agar growth medium and irrigated with various antibiotic and antiseptic solutions under different exposure times. The presence and quantity of the colonies grown were estimated after 24-hour incubation. Repetition of the studies for 5 times with each investigated irrigation solution and microorganism was performed. Optimal irrigation agents were chosen based on the ability to achieve sterility with minimal tissue toxicity. RESULTS The optimal wound irrigation agents for SSI prophylaxis in our study were found to be 0.05% chlorhexidine or triple antibiotic antibiotic solutions. Adding of vancomycin to the irrigation solutions did not show an increase in their effectiveness. Prolonged irrigation exposure time was necessary to achieve sterility of the in vitro model of a surgical site. CONCLUSIONS We recommend 0.05% chlorhexidine or triple antibiotic solution for topical SSI prophylaxis in breast implant surgery. Sufficient time of irrigation can be achieved by maintaining some of the solution in the pocket and delaying drainage for at least 30 minutes. LEVEL OF EVIDENCE 5

Abstract
BACKGROUND Capsular contracture is the most frequent complication after breast augmentation or reconstruction with breast implants. The immune system plays a prominent role in capsular contracture formation, albeit to an unknown extent. Bacterial contamination in situ has been hypothesized to be causative for capsular contracture. How this relates to the immunological processes involved is unknown. This article aims to provide an overview of immunological and bacterial factors involved in development of capsular contracture. MATERIALS AND METHODS We undertook a systematic literature review focused on immunological factors and microbiota in relation to capsular contraction around implants. This systematic review was performed in accordance with the PRISMA guidelines. PubMed, EMBASE, and the Cochrane databases were searched from inception up to October 2016. Included studies were assessed for the following variables: subject characteristics, number of capsules, primary indication for surgery, surgical procedure, follow-up or implant duration, study methods, type of antibiotics or medical therapies and outcomes related to microbiota and immunological factors. RESULTS Data on immunological factors and bacterial contamination were retrieved from 64 included studies. Notably the presence of macrophages and Staphylococcus epidermidis within capsules was often associated with capsular contracture. CONCLUSION This review provides a clear overview of the immunological factors associated with capsular contracture and provides a hypothetical immunological model for development of the disease. Furthermore, an overview of bacterial contamination and associations with capsular contracture has been provided. Follow-up research may result in clinical recommendations to prevent capsular contracture.

Abstract
Background Different research groups have identified microorganisms on breast implants by sonication with significant correlation to the rate of capsular contracture. This substantiated the hypothesis of an infectious etiology of capsular contracture. However, no clinical consequence has been drawn from these results yet. Aim of this study was to review sonication results from breast implants and to evaluate the current preoperative antibiotic regime for breast-implant surgery. Methods We compared breast implant sonication culture results from published reports and our own database. Current perioperative antibiotic recommendations were compared with the susceptibility profile of the found organisms. Results We found Coagulase-negative staphylococci and Propionibacteria to be the main group of microorganism found by sonication on explanted breast implants. Most guidelines recommend cephalosporins for preoperative antibiotical prophylaxis for breast-implant surgery. Conclusion There is a discrepancy between antibiotic activity of commonly used antibiotics for preoperative prophylaxis of surgical site infections, and microorganisms found by sonication on breast implants, suspected to trigger the formation of capsular contracture. A targeted antibiotic prophylaxis for breast implant surgery with glycopeptides (e.g. Vancomycin) should be considered for the prevention of capsular contracture.

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
OBJECTIVES In recent studies, collagen organization was blamed for the formation of capsular contracture which is still a challenging problem after silicone implant-based breast operations. In this study, effects of different concentrations of collagenase enzyme derived from Clostridium histolyticum on the capsular tissue formation around the silicone implants were investigated. The injectable form of collagenase has a routine clinical use in the treatment of both Dupuytren's and Peyronie's diseases. MATERIALS AND METHODS Thirty-two Wistar albino rats were randomized into four groups. A 2 × 1 × 0.3-cm-sized silicone block was inserted inside a dorsal subcutaneous pocket in all groups. After 2 months of insertion, capsule thicknesses around the implants were detected under ultrasonography. This was followed by injection of isotonic saline, 150, 300, and 600 IU in Gr-1, 2, 3, and 4, respectively. All the animals were sacrificed at the end of the first week for histologic sampling to determine fibroblast proliferation, vessel density of the tissue, necrosis, edema, inflammation, and capsule thickness. All the data were statistically analyzed using Kruskal-Wallis and Mann-Whitney U tests and compared for significance of the results. RESULTS There was no significant difference in terms of capsule thinning between the 300 and 600 IU groups but in both groups thinning was significantly higher than the sham group. In the 150 IU group there was no significant thinning as compared to the sham group (p > 0.05). However, complications such as skin necrosis, infection, and seroma formation were seen only in the 600 IU injection group. The optimal safe and effective dose of the enzyme was accepted as 300 IU. The 300 IU injection provided up to 89 % thinning in the capsule tissue. There was thinning of the collagen bundles parallel to capsule thickness. In the 600 IU group, micro-pores were encountered at the thinnest points. CONCLUSION However, the late results and recurrence rates of capsular contracture were not included in this study; collagenase seemed effective for the reduction of capsular tissue around the implants.

Abstract
An adipose tissue engineering chamber model of spontaneous adipose tissue generation from an existing fat flap has been described. However, the chamber does not completely fill with adipose tissue in this model. Here, the effect of adipose tissue extract (ATE) on adipose tissue regeneration was investigated. In vitro, the adipogenic and angiogenic capacities of ATE were evaluated using Oil Red O and tube formation assays on adipose-derived stem cells (ASCs) and rat aortic endothelial cells (RAECs), respectively. In vivo, saline or ATE was injected into the adipose tissue engineering chamber 1 week after its implantation. At different time points post-injection, the contents were morphometrically, histologically, and immunohistochemically evaluated, and the expression of growth factors and adipogenic genes was analyzed by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time PCR. With the exception of the baseline control group, in which fat flaps were not inserted into a chamber, the total volume of fat flap tissue increased significantly in all groups, especially in the ATE group. Better morphology and structure, a thinner capsule, and more vessels were observed in the ATE group than in the control group. Expression of angiogenic growth factors and adipogenic markers were significantly higher in the ATE group. ATE therefore significantly promoted adipose tissue regeneration and reduced capsule formation in an adipose tissue engineering chamber model. These data suggest that ATE provides a more angiogenic and adipogenic microenvironment for adipose tissue formation by releasing various cytokines and growth factors that also inhibit capsule formation.

Abstract
BACKGROUND Subclinical infections, manifest as biofilms, are considered an important cause of capsular contracture. Acellular dermal matrices (ADMs) are frequently used in revision surgery to prevent recurrent capsular contractures. OBJECTIVE We sought to identify an association between capsular contracture and biofilm formation on breast prostheses, capsules, and ADMs in a tissue expander/implant (TE/I) exchange clinical paradigm. METHODS Biopsies of the prosthesis, capsule, and ADM from patients (N = 26) undergoing TE/I exchange for permanent breast implant were evaluated for subclinical infection. Capsular contracture was quantified with Baker Grade and intramammary pressure. Biofilm formation was evaluated with specialized cultures, rtPCR, bacterial taxonomy, live:dead staining, and scanning electron microscopy (SEM). Collagen distribution, capsular histology, and ADM remodeling were quantified following fluorescent and light microscopy. RESULTS Prosthetic devices were implanted from 91 to 1115 days. Intramammary pressure increased with Baker Grade. Of 26 patients evaluated, one patient had a positive culture and one patient demonstrated convincing evidence of biofilm morphology on SEM. Following PCR amplification 5 samples randomly selected for 16S rRNA gene sequencing demonstrated an abundance of suborder Micrococcineae, consistent with contamination. CONCLUSIONS Our data suggest that bacterial biofilms likely contribute to a proportion, but not all diagnosed capsular contractures. Biofilm formation does not appear to differ significantly between ADMs or capsules. While capsular contracture remains an incompletely understood but common problem in breast implant surgery, advances in imaging, diagnostic, and molecular techniques can now provide more sophisticated insights into the pathophysiology of capsular contracture. LEVEL OF EVIDENCE 4 Therapeutic.

Abstract
BACKGROUND Capsular contracture (CC) is a common complication after breast augmentation. Autologous fat grafting may be effective for restoring tissue vascularization and function. OBJECTIVE The authors evaluated the efficacy of autologous fat grafting in a porcine model as a treatment for CC after breast augmentation. METHODS This prospective study was performed in 20 female 30-day-old pigs. Each animal was implanted with three 30-cc textured silicone implants (stage 1 of the experiment). Group A served as the untreated control group. To induce CC, 2 mL of autologous fibrin glue was applied to the pericapsular space in group B and C animals at implantation. Three months after implantation (stage 2), the CCs of all groups were assessed by Baker classification and applanation tonometry (AT). Liposuction was performed in group B to harvest fat for these animals. Three months after group B underwent fat grafting, all 3 groups were reevaluated. Reassessments included Baker classification, AT, histologic analysis, and tensiometry (stage 3). RESULTS The deposition of mature and immature collagen was similar for the 3 groups. The amount of fat remaining around the implanted capsules did not differ significantly between the groups. At stage 3, group B exhibited significantly larger tonometry areas than did group C. The CCs in groups B and C were significantly thicker than those of group A, but the difference between groups B and C was not significant. Capsule rupture forces did not differ significantly between groups A and B but were significantly higher in group C compared with the other groups. CONCLUSIONS Results in this animal model indicate that pericapsular lipoinjection may be a promising treatment for CC in humans.

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
The most common implanted material in the human body consists of silicone. Breast augmentation and breast reconstruction using silicone-based implants are procedures frequently performed by reconstructive and aesthetic surgeons. A main complication of this procedure continues to be the development of capsular contracture (CC), displaying the result of a fibrotic foreign body reaction after the implantation of silicone. For many years, experimental and clinical trials have attempted to analyze the problem of its etiology, treatment, and prophylaxis. Different theories of CC formation are known; however, the reason why different individuals develop CC in days or a month, or only after years, is unknown. Therefore, we hypothesize that CC formation, might primarily be induced by immunological mechanisms along with other reasons. This article attempts to review CC formation, with special attention paid to immunological and inflammatory reasons, as well as actual prophylactic strategies. In this context, the word “biocompatibility” has been frequently used to describe the overall biological innocuousness of silicone in the respective studies, although without clear-cut definitions of this important feature. We have therefore developed a new five-point scale with distinct key points of biocompatibility. Hence, this article might provide the basis for ongoing discussion in this field to reduce single-publication definitions as well as increase the understanding of biocompatibility.

Abstract
BACKGROUND Capsular contracture (CC) is the most frequently reported complication following alloplastic breast augmentation. At present, none of the available preventive measures are effective, and various treatment modalities have been advocated. Reduction of the inflammatory process is critical for successful treatment. Late intracapsular glucocorticosteroid (GC) injections have been somewhat effective for the treatment, but the fine balance between the effectiveness of therapeutic GC dosages and their potential serious side effects is of utmost importance. OBJECTIVES The authors investigate whether instillation of a rapid-acting water-soluble GC in the implant pocket during the early proliferative phase of wound healing is more effective than delayed instillation during the remodeling phase. METHODS Between 2003 and 2009, 33 consecutive patients presenting with CC (Baker grades III and IV) were managed by capsulectomy with implant replacement and corticosteroid therapy immediately as well as 2 to 3 days later through an indwelling catheter left in place for that period. This delayed but early administration is a novel technique for GC injection. RESULTS Complete correction of the contracture with no recurrence was achieved in all patients with a follow-up range of 2 to 10 years. CONCLUSIONS This GC administration technique avoids the potential complications of long-term, slow corticosteroid release. It has a targeted anti-inflammatory effect, probably at a critical stage of the healing process, and could effectively prevent CC following alloplastic breast augmentation.

Abstract
We previously developed and validated a vortexing-sonication technique for detection of biofilm bacteria on the surface of explanted prosthetic joints. Herein, we evaluated this technique for diagnosis of infected breast tissue expanders and used it to assess colonization of breast tissue expanders. From April 2008 to December 2011, we studied 328 breast tissue expanders at Mayo Clinic, Rochester, MN, USA. Of seven clinically infected breast tissue expanders, six (85.7%) had positive cultures, one of which grew Propionibacterium species. Fifty-two of 321 breast tissue expanders (16.2%, 95% CI, 12.3–20.7%) without clinical evidence of infection also had positive cultures, 45 growing Propionibacterium species and ten coagulase-negative staphylococci. While vortexing-sonication can detect clinically infected breast tissue expanders, 16 percent of breast tissue expanders appear to be asymptomatically colonized with normal skin flora, most commonly, Propionibacterium species.

Abstract
BACKGROUND Capsular contracture is the most common side effect of breast implant insertion and the problem that breast surgeons seek to avoid the most. Previous animal studies have proved that an antiadhesive barrier solution (AABS) prevents peri-implant capsule formation. In this study, the authors sought to explore the effect that Guardix-SG(®), an AABS that can encapsulate implants in the form of a gel, can have on capsular contracture. METHOD This study used 12 female New Zealand white rabbits weighing 2.5-3 kg. Implants were inserted into the subpanniculus carnosus plane through an incision in the bilateral midback area. Once the implant was inserted, 3 g of Guardix-SG(®) and normal saline were instilled into the left and right sides, respectively. The rabbits were killed 6 months after the procedure. The intracapsular pressure was measured using tonometry with a 38.2-g circular glass piece, and capsular thickness was measured by dyeing the biopsy specimen with hematoxylin and eosin and Masson's trichrome stain. The myofibroblasts were quantitatively analyzed through monoclonal anti-alpha smooth muscle actin antibody immunohistochemistry staining. RESULTS The intracapsular pressure in the control group (4.51 ± 0.98 mmHg) was significantly higher (p = 0.002) than in the study group (3.51 ± 0.4 mmHg). The average capsular thickness was significantly greater in the control group (0.33 ± 0.15 mm; p = 0.015). In the analysis, the interrelation between capsular thickness and intracapsular pressure was insignificant in both groups, as was the number of myofibroblasts in both groups (p = 0.582). CONCLUSION Through this study, the authors were able to demonstrate that capsular contracture can be suppressed in the rabbit model by instilling Guardix-SG(®) after insertion of cohesive gel implants in the subpanniculus carnosus plane.

Abstract
Abstract
Background
It has been hypothesized that bacterial biofilms on breast implants may cause chronic inflammation leading to capsular contracture. The association between bacterial biofilms of removed implants and capsular contracture was investigated.
Methods
Breast implants explanted between 2006 and 2010 at five participating centres for plastic and reconstructive surgery were investigated by sonication. Bacterial cultures derived from sonication were correlated with patient, surgical and implant characteristics, and the degree of capsular contracture.
Results
The study included 121 breast implants from 84 patients, of which 119 originated from women and two from men undergoing gender reassignment. Some 50 breast prostheses were implanted for reconstruction, 48 for aesthetic reasons and 23 implants were used as temporary expander devices. The median indwelling time was 4·0 (range 0·1–32) years for permanent implants and 3 (range 1–6) months for temporary devices. Excluding nine implants with clinical signs of infection, sonication cultures were positive in 40 (45 per cent) of 89 permanent implants and in 12 (52 per cent) of 23 temporary devices. Analysis of permanent implants showed that a positive bacterial culture after sonication correlated with the degree of capsular contracture: Baker I, two of 11 implants; Baker II, two of ten; Baker III, nine of 23; and Baker IV, 27 of 45 (P < 0·001). The most frequent organisms were Propionibacterium acnes (25 implants) and coagulase-negative staphylococci (21).
Conclusion
Sonication cultures correlated with the degree of capsular contracture, indicating the potential causative role of bacterial biofilms in the pathogenesis of capsular contracture. Registration number: NCT01138891 (http://www.clinicaltrials.gov).

Abstract
BACKGROUND Capsular contracture (CC) is a common complication of breast augmentation that is thought to arise from bacterial contamination and subsequent biofilm formation on the implant. Endogenous breast flora expressed through the nipple may contaminate the sterile field during breast augmentation, acting as a possible source for initiation of biofilm formation. OBJECTIVES The authors investigate the incidence of nipple bacterial contamination with endogenous breast flora after standard chest wall sterilization during breast augmentation. METHODS Bacterial contamination of nipples and nipple shields was assessed in a series of 32 consecutive patients presenting for breast augmentation (63 breasts: 31 bilateral procedures and 1 unilateral procedure). After standard sterilization of the chest wall, occlusive nipple shields were applied and breast augmentation was performed. At the conclusion of breast augmentation, the nipple shields were removed and, using the same swab, both the nipple/areolar area and occlusive dressings were cultured. RESULTS Data from 63 cultured nipples and nipple shields revealed that 22 nipples/nipple shields (34.9%) were positive for bacterial contamination. Three patients, all of whom had negative cultures, developed CC after augmentation. CONCLUSIONS The exposed nipple is a potential source of implant contamination during breast augmentation. An improved understanding of biofilms and related risk factors for CC can provide surgeons with insights for addressing this common complication. Meticulous hemostasis, use of nipple shields, and submuscular device placement may contribute to a lower incidence of CC.

Abstract
Late infections of breast implants are rare occurrences. We present 2 cases of late infections of breast implants, resulting from hematogenous spread from bacterial infection from distant sites. The first case involves a late implant infection following development of a chronic foot sore, caused by Achromobacter xylosoxidans, an aerobic pathogen. The second case describes a late infection, after extensive dental treatment, caused by Streptococcus viridans, a bacterium that normally lives in close association with the teeth and gingiva. On the basis of these 2 cases and others in the literature, systemic antibiotic therapy should be considered in breast implant patients who are exposed to potential bacterial inoculation and bacteremia to prevent late breast infections and subsequent capsular contractures.

Abstract
BACKGROUND Capsular contracture is one of the most common complications associated with breast implants. While the cause of this process has not yet been elucidated, subclinical infection is a likely culprit. OBJECTIVES The authors assess the hypothesis that a probable source of contamination is endogenous breast bacteria, likely originating in the ducts themselves and most concentrated near the nipple. METHODS Twenty-five healthy patients presenting for routine reduction mammaplasty were recruited as study participants. Tissue samples were taken intraoperatively from the periareolar, inframammary, and axillary regions of each sampled breast. Specimens were then processed in the microbiology laboratory, and quantitative bacterial counts were obtained. RESULTS Of the 50 breasts sampled, 19 yielded positive culture results, for a rate of 38%. There was a significant difference in the positive culture rate among all three sites, with increasing quantitative bacterial counts in the axillary, inframammary, and periareolar regions, respectively. The most commonly-identified organisms in this study included various species of Staphylococcus and Propionibacterium acnes, with S. epidermidis being the most common. CONCLUSIONS The breast harbors significant endogenous bacteria that can become the source of spontaneous or postoperative infection. Positive intraoperative cultures with high quantitative counts suggest that breast tissue harbors more bacteria than normal skin flora. Routine perioperative antibiotic prophylaxis may be suboptimal for the prevention of foreign body seeding in this setting. Furthermore, bacterial concentrations are highest in areas with the most ductal tissue, namely the periareolar region. These findings may be helpful when considering which incision site to select for augmentation mammaplasty.

Abstract
Capsular contracture poses a significant clinical and scientific research challenge for breast surgeons. Some researchers have pointed to the surface features of implant devices as being responsible for the potential tightening and hardening of the surrounding capsule. In this article, the authors review the history and development of breast implant design, specifically the data supporting improvements that have potential to mitigate the incidence of capsular contracture. The literature suggests that development of new implant surfaces designed to reduce a patient's foreign body response will improve the safety profile of implant devices and increase patient satisfaction in the long-term.

Abstract
Antiadhesive barrier solution (AABS) has been proven to prevent intraabdominal adhesion by reducing inflammation and fibrosis formation. Because this mechanism can also be applied to capsule formation after the breast implant insertion, we hypothesize that AABS can reduce capsular contraction and evaluate the efficacy of AABS on perisilastic implant capsule formation after submuscular insertion. A silicone block was inserted beneath the panniculus carnosus muscle in 10 rats. The experiment group received 0.1 mL of AABS (Guardix, Hanmi Medical Co.) instilled into the pocket, whereas the control group received 0.1 mL saline solution. Periimplant capsules were excised after 4 weeks and were evaluated for inflammatory cell count, capsular thickness, collagen pattern, and amount of myofibroblast. The inflammatory cell count and the capsular thickness were lower in the experiment group than in the control group (P < 0.05). The collagen pattern was loose and parallel in the experiment group, and the amount of myofibroblast was much less compared with the control group. AABS reduced the amount of inflammatory cells, myofibroblast, and capsular thickness. It also made the collagen fibers in the capsule loose and parallel. Therefore, AABS seemed to be effective in reducing the periimplant capsule formation.
