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
Transgender women seeking gender-affirming breast augmentation often present with differences in preoperative chest measurements and contours in comparison with cisgender women. These include a more robust pectoralis muscle and limited glandular tissue, raising important considerations in determining the optimal anatomical plane for implantation. Abundant literature has described advantages and drawbacks of the available planes for breast augmentation in cisgender women. Certain drawbacks may be more pronounced for transgender women, given their distinct anatomy. The subfascial plane offers lower complication rates than the subglandular plane when using smooth implants, and avoids implant animation and displacement associated with the subpectoral plane. To our knowledge, existing studies have not yet addressed this discussion in the transfeminine population. The goal of this article is to highlight potential benefits of the subfascial plane for gender-affirming breast augmentation, utilizing a case series of 3 transfeminine patients, and to review the literature on surgical techniques and outcomes in this population.

The Histological Composition of Capsular Contracture Focussed on the Inner Layer of the Capsule: An Intra-Donor Baker-I Versus Baker-IV Comparison. Aesthetic Plast Surg 2018; 42:1485-1491. [PMID: 30187083 PMCID: PMC6280822 DOI: 10.1007/s00266-018-1211-1] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2018] [Accepted: 08/05/2018] [Indexed: 11/28/2022]
Abstract
Background Capsular contracture remains one of the major complications after breast implantation surgery. The extent of capsular contraction is scored using the Baker scale. The aim of this study was to compare intra-individual Baker-I with Baker-IV capsules, and in particular the prevalence and histological properties of the inner capsule layer. Methods Twenty capsules from ten patients were included after bilateral explantation surgery due to unilateral capsular contracture (Baker-IV) after cosmetic augmentation with textured implants. All capsules underwent (immune-)histochemical analysis: haematoxylin–eosin (morphology), CD68 (macrophages), cytokeratin (epithelial cells) and vimentin (fibroblasts), and were visually scored for cell density and the presence of an inner layer and measured for thickness. Results Baker-IV (n = 10) capsules were significantly thicker compared to Baker-I (n = 10) capsules (P = 0.004). An inner layer was present in 8 Baker-I capsules. All Baker-I capsules were vimentin and CD68-positive and cytokeratin-negative. Positive vimentin was seen throughout the inner layer, and CD-68 staining was observed adjacent to the intermediate capsule layer. In contrast, only 2 Baker-IV capsules had an inner layer, of which only 1 showed the same profile as Baker-I capsules (P = 0.016). No cytokeratin positivity was seen in any capsule. In Baker-IV capsules, outer layers showed more positivity for both vimentin and CD68. Conclusion The inner layer is morphologically consistent with synovial metaplasia and is more prevalent in healthy, uncontracted Baker-I capsules. This inverse relation between the presence of the inner layer and higher Baker classification or pathological contracture could indicate a protective role of the inner layer against capsular contracture formation.

Abstract
The 'waterfall effect' is a descriptive term to indicate a sliding ptosis of parenchymal breast tissue over a fixed or encapsulated implant. It occurs more frequently than surgeons anticipate and especially over the longer term after augmentation. Certain breast implants are more prone to contribute to this problem as are implants placed in submuscular pockets that ride high, especially in women with anatomical musculoskeletal variance or asymmetry. This article describes the aetiology of sliding ptosis in more detail, the relevant anatomy and the surgical correction. Understanding the problem enables the surgeon to plan the appropriate procedure and obtain proper informed consent. It is possible that a two stage procedure is necessary should the upper pole of breast require a debulk, either early (3 to 12 months) or later as the breast may slide with ageing of the tissues. The waterfall effect of breast parenchyma over implants is only apparent when the upper torso of the woman is undressed and she is in an erect posture. A significant number of women are happy with this situation and therefore no further action is required. Those that want an improved appearance in these circumstances can try autologous fat transfer to rebulk the surrounding tissues but generally the most likely solution involves a mastopexy with or without implant exchange. The results are highly rewarding but the scars are the legacy. Mastopexy augmentation is a difficult procedure and should only be performed by experienced surgeons. Many surgeons prefer a two stage approach with either an implant based augmentation first to limit scars and see if the patient is happy with the outcome or a first stage mastopexy to decide whether implants or fat graft are actually required as a secondary procedure.

Abstract
BACKGROUND Despite 82% of patients reporting psychosocial improvement following breast reconstruction, only 33% patients choose to undergo surgery. Implant reconstruction outnumbers autologous reconstruction in many centres. METHODS A systematic review of the literature was undertaken. Inclusion required: (I) Meta-analyses or review articles; (II) adult patients aged 18 years or over undergoing alloplastic breast reconstruction; (III) studies including outcome measures; (IV) case series with more than 10 patients; (V) English language; and (VI) publication after 1(st) January, 2000. RESULTS After full text review, analysis and data extraction was conducted for a total of 63 articles. Definitive reconstruction with an implant can be immediate or delayed. Older patients have similar or even lower complication rates to younger patients. Complications include capsular contracture, hematoma and infection. Obesity, smoking, large breasts, diabetes and higher grade tumors are associated with increased risk of wound problems and reconstructive failure. Silicone implant patients have higher capsular contracture rates but have higher physical and psychosocial function. There were no associations made between silicone implants and cancer or systemic disease. There were no differences in outcomes or complications between round and shaped implants. Textured implants have a lower risk of capsular contracture than smooth implants. Smooth implants are more likely to be displaced as well as having higher rates of infection. Immediate breast reconstruction (IBR) gives the best aesthetic outcome if radiotherapy is not required but has a higher rate of capsular contracture and implant failure. Delayed-immediate reconstruction patients can achieve similar aesthetic results to IBR whilst preserving the breast skin if radiotherapy is required. Delayed breast reconstruction (DBR) patients have fewer complications than IBR patients. CONCLUSIONS Implant reconstruction is a safe and popular mode of post-mastectomy reconstruction. Evidence exists for the settings in which complications are more likely, and we can now more reliably predict outcomes of reconstruction on an individual basis and assess patient suitability.

Abstract
The influence of age on capsular contracture rates remains unclear. Most studies have only investigated early capsule development and not whether a link between age at primary surgery and the later development of capsular fibrosis exists. To clarify whether patient age impacts the development of late capsular fibrosis, the authors conducted a retrospective case study involving 43 patients who presented for surgical revision of capsular contracture (Baker grade ≥III) between four and 40 years after primary breast augmentation. Possible correlations between age and implant placement were analyzed. Late presentation of capsular fibrosis occurred a mean of 15.6 years after primary augmentation, with a slightly negative, but not significant, correlation between age at primary operation and duration of implant placement. Patients <40 years of age underwent an operative revision after a mean of 18.9 years, while patients ≥40 years of age needed an operative revision a mean of 11.9 years after primary breast augmentation (P=0.0368). The results suggest that with advancing age, the average time to develop capsular fibrosis is significantly shorter in individuals who develop capsular contracture. As more data are collected, appropriate advice can be provided to patients regarding factors that influence the long-term outcomes of breast augmentation.

Polyurethane-coated breast implants revisited: a 30-year follow-up. Arch Plast Surg 2015; 42:186-93. [PMID: 25798390 PMCID: PMC4366700 DOI: 10.5999/aps.2015.42.2.186] [Citation(s) in RCA: 50] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2014] [Revised: 12/06/2014] [Accepted: 12/09/2014] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND Polyurethane coating of breast implants has been shown to reduce capsular contracture in short-term follow-up studies. This 30-year study is the longest examination of the use of polyurethane-coated implants and their correlation with capsular contracture. METHODS This study evaluates the senior surgeon's (F.D.P.) experience with the use of polyurethane-coated implants in aesthetic breast augmentation in 382 patients over 30 years. Follow-up evaluations were conducted for six months after surgery. After the six-month follow-up period, 76 patients returned for reoperation. The gross findings, histology, and associated capsular contracture were noted at the time of explantation. RESULTS No patient during the six-month follow-up period demonstrated capsular contracture. For those who underwent reoperation for capsular contracture, Baker II/III contractures were noted nine to 10 years after surgery and Baker IV contractures were noted 12 to 21 years after surgery. None of the explanted implants had macroscopic evidence of polyurethane, which was only found during the first five years after surgery. The microscopic presence of polyurethane was noted in all capsules up to 30 years after the original operation. CONCLUSIONS An inverse correlation was found between the amount of polyurethane coating on the implant and the occurrence of capsular contracture. Increasingly severe capsular contracture was associated with a decreased amount of polyurethane coating on the surface of the implants. No contracture occurred in patients whose implants showed incomplete biodegradation of polyurethane, as indicated by the visible presence of polyurethane coating. We recommend research to find a non-toxic, non-biodegradable synthetic material as an alternative to polyurethane.

Abstract
Background A large number of clinical studies have reported that the different materials used in breast implants were a possible cause of the different incidence rates of capsular contracture observed in patients after implantation. However, this theory lacks comprehensive support from evidence-based medicine, and considerable controversy remains. Objectives In this study, a cumulative systematic review examined breast augmentation that used implants with textured or smooth surfaces to analyze the effects of these two types of implants on the occurrence of postoperative capsular contracture. Methods We conducted a comprehensive search of literature databases, including PubMed and EMBASE, for clinical reports on the incidence of capsular contracture after the implantation of breast prostheses. We performed a cumulative meta-analysis on the incidence of capsular contracture in order from small to large sample sizes and conducted subgroup analyses according to the prosthetic material used, the implant pocket placement, the incision type and the duration of follow-up. Relative risks (RR) and 95% confidence intervals (CI) were used as the final pooled statistics. Results This meta-analysis included 16 randomized controlled trials (RCTs) and two retrospective studies. The cumulative comparison of textured and smooth breast implants showed statistical significance at 2.13 (95% CI, 1.18-3.86) when the fourth study was entered into the analysis. With the inclusion of more reports, the final results indicated that smooth breast implants were more likely to be associated with capsular contracture, with statistical significance at 3.10 (95% CI, 2.23-4.33). In the subgroup analyses, the subgroups based on implant materials included the silicone implant group and the saline implant group, with significant pooled statistical levels of 4.05 (95% CI, 1.97-8.31) and 3.12 (95% CI, 2.19-4.42), respectively. According to implant pocket placement, a subglandular group and a submuscular group were included in the analyses, and only the subglandular group had a statistically significant pooled result of 3.59 (95% CI, 2.43-5.30). Four subgroups were included in the analyses according to incision type: the inframammary incision group, the periareolar incision group, the transaxillary incision group and the mastectomy incision group. Among these groups, only the pooled results of the inframammary and mastectomy incision groups were statistically significant, at 2.82 (95% CI, 1.30-6.11) and 2.30 (95% CI, 1.17-4.50), respectively. Three follow-up duration subgroups were included in the analyses: the one-year group, the two- to three-year group and the ≥five-year group. These subgroups had statistically significant results of 4.67 (95% CI, 2.35-9.28), 3.42 (95% CI, 2.26-5.16) and 2.71 (95% CI, 1.64-4.49), respectively. Conclusion In mammaplasty, the use of textured implants reduces the incidence of postoperative capsular contracture. Differences in implant pocket placement and incision type are also likely to affect the incidence of capsular contracture; however, this conclusion awaits further study.

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
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.

[PMID: 25289261 PMCID: PMC4186301 DOI: 10.1097/gox.0000000000000001] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2013] [Accepted: 09/06/2013] [Indexed: 01/09/2023]
Abstract
BACKGROUND The Level of Evidence rating was introduced in 2011 to grade the quality of publications. This system evaluates study design but does not assess several other quality indicators. This study introduces a new "Cosmetic Level of Evidence And Recommendation" (CLEAR) classification that includes additional methodological criteria and compares this new classification with the existing system. METHODS All rated publications in the Cosmetic Section of Plastic and Reconstructive Surgery, July 2011 through June 2013, were evaluated. The published Level of Evidence rating (1-5) and criteria relevant to study design and methodology for each study were tabulated. A new CLEAR rating was assigned to each article, including a recommendation grade (A-D). The published Level of Evidence rating (1-5) was compared with the recommendation grade determined using the CLEAR classification. RESULTS Among the 87 cosmetic articles, 48 studies (55%) were designated as level 4. Three articles were assigned a level 1, but they contained deficiencies sufficient to undermine the conclusions. The correlation between the published Level of Evidence classification (1-5) and CLEAR Grade (A-D) was weak (ρ = 0.11, not significant). Only 41 studies (48%) evaluated consecutive patients or consecutive patients meeting inclusion criteria. CONCLUSIONS The CLEAR classification considers methodological factors in evaluating study reliability. A prospective study among consecutive patients meeting eligibility criteria, with a reported inclusion rate, the use of contemporaneous controls when indicated, and consideration of confounders is a realistic goal. Such measures are likely to improve study quality.

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 Silicone breast implants are used to a wide extent in the field of plastic surgery. However, capsular contracture remains a considerable concern. This study aimed to analyze the effectiveness and applicability of an ultracision knife for capsulectomy breast surgery. METHODS A prospective, single-center, randomized study was performed in 2009. The inclusion criteria specified female patients 20-80 years of age with capsular contracture (Baker 3-4). Ventral capsulectomy was performed using an ultracision knife on one side and the conventional Metzenbaum-type scissors and surgical knife on the collateral side of the breast. Measurements of the resected capsular ventral fragment, operative time, remaining breast tissue, drainage time, seroma and hematoma formation, visual analog scale pain score, and sensory function of the nipple-areola complex were assessed. In addition, histologic analysis of the resected capsule was performed. RESULTS Five patients (median age, 59.2 years) were included in this study with a mean follow-up period of 6 months. Three patients had Baker grade 3 capsular contracture, and two patients had Baker grade 4 capsular contracture. The ultracision knife was associated with a significantly lower pain score, shorter operative time, smaller drainage volume, and shorter drainage time and resulted in a larger amount of remaining breast tissue. Histologic analysis of the resected capsule showed no apoptotic cells in the study group or control group. CONCLUSIONS The results suggest that ventral capsulectomy with Baker grade 3 or 4 contracture using the ultracision knife is feasible, safe, and more efficient than blunt dissection and monopolar cutting diathermy and has a short learning curve.

Abstract
BACKGROUND Implant breast augmentation is one of the most frequently performed surgical procedures, and fungal infection still is considered exceptional. This report presents a case of bilateral breast implant infection by multidrug-resistant Candida albicans treated with a targeted antifungal therapy. METHODS A young woman presented with breast pain and asymmetry as well as implant superficialization in the left breast 3 years after bilateral tuberous breast correction with implant insertion. She did not report any trauma to the chest wall or recent systemic infections. The breast was evaluated through mammary compliance analysis and magnetic resonance imaging (MRI). RESULTS At surgery, both implants showed capsule contracture and were surrounded by a gelatinous yellow-brown and turbid fluid, which was sent for microbial and fungal analysis. A bilateral capsulectomy was performed. After copious irrigation of the subglandular pockets, submuscular pockets were created, and implants were substituted. Culture swabs tested positive for C. albicans and showed drug resistance to amphotericin B, fluconazole, itraconazole, and voriconazole on the fungal antibiogram. Targeted antifungal therapy with caspofungin was administrated in association with oral antibiotic therapy. Follow-up assessment at 1, 3, 6, 12, and 24 months did not show any infection or contracture relapse. CONCLUSIONS This is the first report in the literature on a breast implant infection by a multidrug-resistant C. albicans. The study focused on the association between fungal contamination and capsular contracture and investigated the importance of a fungal antibiogram in cases of suspected prosthesis infection for performance of a targeted antifungal treatment.

Abstract
BACKGROUND This study aimed to explore the treatment of capsular contracture after augmentation mammaplasty by insertion of a breast prosthesis anterior to the original capsule. METHODS Through transaxillary or submammary incisions and small capsular incisions, 14 patients (18 breasts) with Baker grades 3 and 4 capsular contractures had their breast implants removed and repositioned anterior to the primary capsule. The primary capsules were preserved. RESULTS Satisfactory results (Baker 1) were achieved for all 14 patients during the 29-month follow-up period. CONCLUSION The described method offers numerous advantages for the treatment of capsular contracture. It is minimally invasive and performed through a small axillary or submammary incision. It is simple, offers little trauma, has less bleeding, and results in a good outcome based on our follow-up assessment in the medium term. It is our preferred method for the treatment of capsular contracture.

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.

Abstract
Our study addressed the question of whether surface properties of modern standard gel prostheses may have a measurable impact on the fibrogenic properties of cultured human dermal fibroblasts. Fibroblasts were isolated from breast implants by using the explant culture technique and incubated either on smooth or on textured silicone elastomere surfaces. Fibroblast growth was observed 4 weeks following incubation. Expression of transforming growth factor (TGF)-β1 was measured after cell culture. Incubated fibroblasts on textured surfaces showed a fivefold lower growth rate during all experiments. TGF-β1 expression was lowered in smooth surface fibroblasts compared with textured surface cultures. Our results show that smooth and textured silicone surfaces of modified gel breast implants have a different impact on the fibroproliferative properties of dermal fibroblasts. These preliminary results seem promising and we aim to further perform qualitative and quantitative analyses of the inflammatory processes in the environment of the implant and their link to the TGF-β pathway.

Abstract
Although the need for mastectomy has been evident for many years, postmastectomy reconstruction has been recognized as an achievable outcome for only a little over a century. A review of the evolution of both autologous and prosthetic options for reconstruction was undertaken. The earliest attempts at reconstruction used autologous techniques that were either unsuccessful, not reproducible, or were associated with significant morbidity. Prosthetic techniques became sought after, with silicone prostheses widely used until concerns about potential adverse effects led to the investigation of alternate options. With these concerns shown to be unfounded, silicone and saline prostheses evolved with successive generations of implants. Concurrent advances in reconstructive surgery led to a revival in autologous techniques for breast reconstruction, with microsurgical free-tissue transfer potentiating a new range of potential donor sites. The abdominal wall became the donor site of choice, and with the advent of perforator flaps, morbidity associated with flap harvest was minimized. In cases where the abdominal wall is unsuitable, flaps such as the superior and inferior gluteal artery perforator flaps, the musculocutaneous gracilis flap, and the "stacked" deep inferior epigastric artery perforator flap are frequently used options. The development of minimally invasive techniques for implant placement and flap harvest, such as endoscopy, continue to evolve, and research in tissue engineering offers a vision for a future without the need for a donor site.

Abstract
In a cross-sectional postal survey, we compared patient-reported outcomes in patients undergoing breast reconstruction with the deep inferior epigastric perforator (DIEP) flap or an expandable breast implant (EBI). We included 34 consecutive patients who had breast reconstruction with DIEP flap and 30 patients with EBI. Outcomes were assessed using the Short Form 36 (SF-36) quality of life questionnaire, two study-specific patient satisfaction questionnaires and a visual analogue scale (VAS) on cosmetic result. There were no significant differences in SF-36 subscale scores between the two groups. On the study-specific questionnaire, more patients in the DIEP group were satisfied with the appearance of their breast (P<0.0005) and reported an improved social relationship (P=0.02), and fewer patients were sad about their body image (P=0.01) after reconstruction than in the EBI group. On the other study-specific items, satisfaction was similar in the two groups. On all five VAS items, DIEP patients reported better cosmetic results than EBI patients. We conclude that patient satisfaction and cosmetic outcome were better after breast reconstruction with the DIEP flap compared with EBI, while there was no difference in health-related quality of life.

Abstract
Novagold breast implants were withdrawn from use in the UK in December 2000 due to concerns about the metabolic fate of the implant filler material, the hydrogels polyvinylpyrrolidine (PVP) and guar gum. A total of 250 women in the UK had these implants, 66 of which were performed in our unit. A total of 44% of cases needed further surgery for complications. Capsular contracture requiring surgical intervention occurred in 32%. Symptomatic ruptures occurred in 10.5%. Infection was recorded in 1.5%. From comparison with published data, the incidence of capsular contracture is comparable, but the occurrence of rupture is almost twice that of saline-filled implants. It is hypothesised that an osmotic gradient occurs due to the hydrogel filler causing the implants to swell and weaken the elastomer shell. When the PVP/guar gum filler is released into the subcutis, a vigorous tissue reaction occurs causing pain and swelling. These results show that this composition of implant poses potential risks, which should be considered by manufacturers in the future. We advise removal of symptomatic implants, as rupture is likely to have occurred.

Abstract
The aim of this work is to precise the indications to respect and the pitfalls to avoid in prosthesis setting using anatomical cohesive silicone gel implants.135 patients that undergone a reconstructive or cosmetic prosthesis setting were reviewed. Patients satisfaction has been assessed basing on the breast shape, consistency and symmetry. Complications (both usual and specific) were assessed and analysed. The results for mammary reconstruction after expansion or autologous flap and for cosmetic submuscular breast augmentation were good. Complications were unusual as far as the appropriate surgical procedure had been performed rigorously. These implants are an interesting alternative solution to round shape prosthesis in reconstruction indication. In breast augmentation border line indications, a beautiful result may be expected using these implants.

Abstract
One hundred and seven breast cancer patients underwent subcutaneous mastectomy and immediate reconstruction with a subcutaneously-placed, round, saline-filled prosthesis with a textured surface. The primary aim of this prospective study was to determine the frequency of capsular contracture in both irradiated and non-irradiated breasts after this operation. Two different types of round implants with different pore sizes on their textured surfaces, Siltex and Microcell, were randomly chosen. Twenty-four patients received radiotherapy within the first year following the operation. Capsular contracture was measured by the Baker/Palmer classification and by applanation tonometry at regular intervals for 5 years or as long as the patients lived (median 60 months). Twenty-two patients (20.6%) developed capsular contracture, defined as Baker three or four. Sixteen of those were reoperated, 15 with open capsulotomy with or without implant exchange, one with closed compression capsulotomy, and monitored thereafter for 5 years or until death (median 60 months). All 107 patients could be monitored for 2 years, while 87 reported for the 5-year follow-up. The rate of capsular contracture was significantly higher (p=0.01) for irradiated breasts than for non-irradiated ones, 41.7 and 14.5%, respectively. It was slightly higher (p<0.05) for large-pore implants than for those with smaller (and more numerous) pores. There was a good correlation between the two different methods for measuring capsular contracture. None of the 16 reoperated patients had a recurrence of capsular contracture within 5 years. The results indicate a high rate of capsular contracture after this operation, especially when followed by radiation. However, a fairly simple procedure to treat capsular contracture seems to give good long-term results.

Abstract
The use is to oppose silicone and saline implants. Both are used in regular practice. What are the arguments to choose in between the two types? We separated three different criteria groups: prosthesis characteristics, surgical procedures and complications. For each criterion we made a review of literature looking for arguments in favour or against silicone or saline implants. The number of criteria to choose the correct type of prosthesis is very important. We conclude that surgeon experience; desires of the patient and evolution of prosthesis are the most important criteria.

Abstract
Envelope structure has evolved since the seventies. Indeed, low-bleed implants allow an important reduction of capsular contracture for silicone filled implants. Later, textured implants permit an additional reduction of capsular contracture, especially when positioned in a retroglandular pocket. Whereas many studies confirm these findings, the interest of textured implants in the retromuscular plane is not really clear, even if some authors recommend it. Due to the need of a tissular anchorage, anatomical implants are not manufactured with smooth envelopes.

Abstract
Little has been published regarding the treatment of patients with long-established capsular contracture after previous submuscular or subglandular breast augmentation. This study reviews 7 years of experience in treating established capsular contracture after augmentation mammaplasty by relocating implants to the "dual-plane" or partly subpectoral position. A retrospective chart review was performed on all patients who were treated for capsular contracture using this technique between 1993 and 1999. Data collected included the date of the original augmentation, the original implant location, date of revision and type of implant used, length of follow-up, outcome, and any ensuing complications. Different surgical techniques were used, depending on whether the prior implant was located in a subglandular or submuscular plane. All patients had revisions such that their implants were relocated to a dual plane, with the superior two thirds or so of the implant located beneath the pectoralis major muscle and the inferior one third located subglandularly. Of 85 patients reviewed, 54 had their original implants in a submuscular position and 31 had their initial augmentation in a subglandular position. Of the 54 patients whose implants were initially submuscular, 23 patients (43 percent) had silicone gel implants, 15 patients (28 percent) had double-lumen implants, and the remaining 16 patients (30 percent) had saline implants. Of the 31 patients whose implants were initially subglandular, 20 patients (65 percent) had silicone gel implants, three patients (10 percent) had double-lumen implants, and the remaining eight patients (26 percent) had saline implants. Fifty-one patients (60 percent) had replacement with saline implants (37 smooth saline, 14 textured saline), whereas 34 (40 percent) had silicone gel implants (seven smooth gel, 27 textured gel). The average time from previous augmentation to revision was 9 years 9 months. The average follow-up time after conversion to the dual-plane position was 11.5 months. Only three of 85 patients required reoperation for complications, all of which involved some degree of implant malposition. Of patients converted to the dual plane, 98 percent were free of capsular contracture and were Baker class I at follow-up, whereas 2 percent were judged as Baker class II. There were no Baker level III or IV contractures at follow-up. The dual-plane method of breast augmentation has proved to be an effective technique for correcting established capsular contracture after previous augmentation mammaplasty. This technique appears to be effective when performed with either silicone or saline-filled implants.

Abstract
BACKGROUND A study was undertaken to investigate long-term histological changes in the environment of breast implants and their correlation with complains at the time of capsular contracture defined by the Baker score. METHOD The collagenous capsules of 53 silicone breast implants from 43 patients (23 smooth and 30 textured devices) were evaluated histologically for capsular thickness, the presence of histiocytes, the amount of silicone and calcification in the capsule, and the presence of synovial-like metaplasia of the inner surface of the capsule with light microscopy and polarised light. All parameters were correlated with the Baker score. RESULTS A significantly higher degree of the Baker score was found with increasing patient age (p<0.001), implant duration (p<0.02), and capsular thickness (p<0.009). A trend towards greater capsular thickness was documented in patients who had a breast augmentation for cosmetic reasons. Synovial-like metaplasia was seen in 28 capsules (52.8%). The highest incidence was found in textured implants with a duration of less than 5 years. Histiocytic inflammation was more common in patients with clinical symptoms (p<0.001) and around subglandular implants (p<0.096). CONCLUSIONS The histological findings of breast capsules were related to: the nature of the device surface (smooth versus textured), implant duration, and the degree of capsular contracture. Capsular contracture (Baker score of 3 or 4) was related to implant duration, capsule thickness, patient age, and inflammation.
