Abstract
BACKGROUND Capsular contracture (CC) is a common complication following implant-based breast surgery, often requiring surgical intervention. Yet, little is known about risk factors and outcomes following CC surgery. METHODS We reviewed the American College of Surgeons National Surgical Quality Improvement Program database (2008-2021) to identify female patients diagnosed with CC and treated surgically. Outcomes of interest included the incidence of surgical and medical complications at 30-days, reoperations, and readmissions. Confounder-adjusted multivariable analyses were performed to establish risk factors. RESULTS 5,057 patients with CC were identified (mean age: 55 ± 12 years and mean body mass index [BMI]: 26 ± 6 kg/m2). While 2,841 (65%) women underwent capsulectomy, capsulotomy was performed in 742 patients (15%). Implant removal and replacement were recorded in 1,160 (23%) and 315 (6.2%) cases, respectively. 319 (6.3%) patients experienced postoperative complications, with 155 (3.1%) reoperations and 99 (2.0%) readmissions. While surgical adverse events were recorded in 139 (2.7%) cases, 86 (1.7%) medical complications occurred during the 30 day follow-up. In multivariate analyses, increased BMI (OR: 1.04; p = 0.009), preoperative diagnosis of hypertension (OR: 1.48; p = 0.004), and inpatient setting (OR: 4.15; p < 0.001) were identified as risk factors of complication occurrence. CONCLUSION Based on 14 years of multi-institutional data, we calculated a net 30 day complication rate of 6.3% after the surgical treatment of CC. We identified higher BMI, hypertension, and inpatient setting as independent risk factors of postoperative complications. Plastic surgeons may wish to integrate these findings into their perioperative workflows, thus optimizing patient counseling and determining candidates' eligibility for CC surgery.

Abstract
Background Both biologic and synthetic mesh have been found to reduce the risk of capsular contracture, yet there is limited data assessing the use of these scaffold materials in revision breast reconstruction. Objectives This investigation sought to assess the ability of either biologic or synthetic mesh to prevent capsular contracture in the revision breast reconstruction population. Methods A retrospective chart review was conducted of implant-based revision reconstructions performed by the senior author between 2008 and 2023. Patient demographics and outcomes were assessed, including the incidence of Baker Grade III or IV capsular contractures. Results were compared between biologic and synthetic mesh groups using univariate and multivariate analysis. Results Ninety-five breasts underwent revision reconstruction with 90 (94.7%) for correction of malposition, 4 (4.2%) for size change, and 1 (1.1%) for revision after additional oncologic breast surgery. Of these breasts, 26 (27.4%) used biologic mesh and 69 (72.6%) used synthetic mesh. Capsular contracture occurred in 1 (3.8%) biologic mesh breast and 4 (5.8%) synthetic mesh breasts. There was no significant difference in the incidence of capsular contracture between the 2 groups (P = 1.000). None of the recorded demographics were risk factors for capsular contracture, including the use of biologic or synthetic mesh (P = .801). Conclusions Both biologic and synthetic mesh are successful at preventing capsular contracture in patients undergoing implant-based revision reconstruction. This adds to the growing evidence that both scaffold materials can be used in complex revision breast reconstruction to aid in preventing capsular contracture. Level of Evidence 4

Abstract
BACKGROUND Capsular contracture is a known complication of breast augmentation and is among the top reasons for revisional breast augmentation procedures. The use of acellular dermal matrix (ADM) has been shown to reduce the rate of capsular contracture in breast reconstruction and augmentation, theorizing that it acts as a protective barrier between the implant capsule and inflammatory process responsible for capsular contracture. The role of ADM in treatment of capsular contracture has been investigated in numerous studies, with a variety of ADMs. OBJECTIVES The aim of this study was to perform a systematic review of existing literature on the use of ADM for treatment of capsular contracture in aesthetic breast augmentation patients to investigate differences in efficacy of ADM types. METHODS The PubMed, Embase, and CINAHL databases were systematically reviewed for articles pertaining to capsular contracture, acellular dermal matrices, and breast augmentation. Number of patients, type of ADM, Baker grade, follow-up time, complication rate, and capsular contracture rate were recorded from identified articles. Data was pooled from studies to calculate a capsular contracture rate for each ADM type, with a chi-squared test performed for analysis. Identified studies with a comparative group were included in a meta-analysis utilizing risk ratio (RR) to assess the efficacy of ADM. RESULTS Nine articles including ADM for treatment of capsular contracture in breast augmentation met criteria for inclusion, with a total of 481 breasts. Strattice was the most commonly utilized ADM (n = 391), followed by AlloDerm (n = 57). There was a statistically significant difference in efficacy of ADM among the studied ADM types (P < .001). AlloDerm, FlexHD, and DermaMatrix had the lowest capsular contracture rates (0%). NeoForm and SurgiMend had the highest capsular contracture rates (each 25%, but with n = 4 and n = 8, respectively). Strattice had a capsular contracture rate of 1.53% in the pooled data, and meta-analysis showed that Strattice reduced the risk of capsular contracture (RR 0.14 [95% CI 0.06, 0.31]) compared with conventional treatment. CONCLUSIONS Acellular dermal matrices appear to be effective at treating capsular contracture after breast augmentation while maintaining a low complication rate. Overall capsular contracture rates are low with the use of ADM. There is a statistically significant difference in efficacy among ADM types. Meta-analysis shows that Strattice is effective at reducing the risk of capsular contracture in breast augmentation patients when compared to conventional treatment. Future research, especially in the form of randomized controlled trials, is needed to further investigate the efficacy of various ADMs in the treatment of capsular contracture. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Capsular contracture is the most common complication of breast implantation surgery. Bacterial contamination was considered to play an important role in the occurrence of capsular contracture, and Gram-positive bacteria such as Staphylococcus epidermidis were discovered in the clinical specimens. Lipoteichoic acid (LTA) was a component of the cell wall of Gram-positive bacteria and was sufficient in the pathogenicity of the bacteria. The authors assumed that LTA could trigger the immunologic response against the implant and cause capsular contracture. METHODS The authors developed a rat model of capsular contracture by repeated injection of 10 μg/mL LTA. The histologic changes of the capsule tissue were measured by hematoxylin and eosin, sirius red, Masson, and immunohistochemical staining. The expression of related cytokines was measured by quantitative real-time polymerase chain reaction. The downstream pathway activation was shown by Western blot. The authors also applied tocilizumab, an interleukin (IL)-6 receptor antagonist, to verify the role of IL-6 in this pathologic process. RESULTS The authors discovered that repeated LTA injection, at a low concentration, could induce the thickening of capsule tissue, the deposition of collagen fiber, and the activation of myofibroblasts. The IL-6/signal transducer and activator of transcription 3 signaling pathway was activated in this process, and the inhibition of IL-6 receptor could relieve the symptoms. B cells and T-helper cells, especially T-helper type 1, could be related to this phenomenon. CONCLUSIONS The authors' research corroborated that subclinical infection could trigger capsular contracture, and the immune system played an important role in this process. The authors' results provided a possible research direction for the mechanism of bacterial infection-induced immune response against breast implants. CLINICAL RELEVANCE STATEMENT The authors' research provides a possible research direction for the mechanism of bacterial infection-induced immune response against breast implants, and a potential target for predicting the prognosis of capsular contracture.

Submuscular Implant-Based Breast Reconstruction Using a Musculofascial Pocket Formed by the Pectoralis Major Muscle and the Serratus Anterior Muscle Fascia: A Novel Surgical Approach. World J Surg 2022; 46:1451-1456.

Abstract
BACKGROUND Subpectoral implant-based breast reconstruction following mastectomy commonly severs the inferior border of the pectoralis major muscle for better projection of the lower pole. This can affect a patient's postoperative motor function and result in animation deformity. Implant-based breast reconstruction using partial muscle coverage with an acellular dermal matrix (ADM) can be costly. There is an unmet clinical need for a novel surgical method for submuscular implant-based breast reconstruction. METHODS We describe an innovative technique for submuscular implant-based breast reconstruction following mastectomy. The approach utilizes the serratus anterior muscle fascia connected to the lateral margin of the pectoralis major muscle to form a lateral tissue pocket for implant coverage. This method preserves the inferior border of the pectoralis major muscle and minimizes the size of ADM coverage. Patient satisfaction on the BREAST-Q Reconstruction Module and complications were assessed 12 months after surgery. RESULTS The novel surgical design was safe and used minimal ADM (6 × 5cm2). Mean satisfaction with breasts was 61 ± 4.7 (range, 48-73), mean psychosocial well-being was 66 ± 10 (range, 50-93), and mean sexual well-being was 47 ± 7.8 (range, 27-70). Animation deformity was avoided by preserving the inferior border of the pectoralis major muscle. Rates of revision (7.6%) and postsurgical seroma (3.4%) were low, and capsular contracture was minimal. CONCLUSIONS Submuscular implant-based breast reconstruction following mastectomy utilizing the serratus anterior muscle fascia connected to the lateral margin of the pectoralis major muscle to form a lateral tissue pocket for implant coverage is safe, feasible, and generates good aesthetic outcomes.

Abstract
Background Capsular contracture (CC) represents one of the most common complications in breast reconstruction surgery, impairing final result and patients’ well-being. The role of acellular dermal matrixes (ADM) has been widely described for the treatment and prevention of contracture. The aim of the study was to evaluate the efficacy and safety of complete implant coverage with porcine-derived ADM in preventing CC limiting complications. In addition, patients’ reported outcomes were evaluated in order to define the role of ADM in improving sexual, physical and psychosocial well-being and satisfaction. Methods 42 patients who underwent surgical treatment of 46 contracted reconstructed breasts from May 2018th to May 2019th were collected in the two groups (ADM group vs. Control group). Results The ADM group showed lower rate of CC recurrence and a higher rate of implant losses and minor complications. A significant difference was observed in red breast syndrome (27.3% in the ADM group vs. absent in control the group) and skin ulceration rates (18.2% in the ADM group vs. 4.18% in the control group). As for patients’ perceived outcomes, the ADM group showed a statistically significant higher postoperative Satisfaction of Breast Scale score compared to the control group. In addition, a significant difference was observed in the improvement of Physical Well-Being of the Chest Scale and the Satisfaction of Breast Scale after surgery, in favor to the ADM group. Conclusion Complete implant coverage with ADM may reduce the risk of CC recurrence in breast reconstruction. An accurate patient selection allows minimizing complications improving patient well-being and satisfaction.

Abstract
BACKGROUND Large and ptotic breasts are considered an anatomical contraindication for nipple sparing mastectomy (NSM). Necrosis rates can be as high as 76%. The authors examined whether targeted preshaping mastopexy/reduction combined with simultaneous two-stage preshaping of the implant pocket prepares for an uneventful implant reconstruction. METHODS Macromastia and ptosis patients opting for risk-reducing NSM or having a peripherally localized carcinoma in situ, were offered a two-stage mastopexy/reduction simultaneously with preshaping of the implant pocket by subpectoral expansion. Only the inferior pedicle bearing the nipple-areola complex (NAC), remained. A delayed secondary NSM and tissue expander-to-implant reconstruction was scheduled 3 months later. The use of an acellular dermal matrix (ADM) was not necessary because the capsule around the expander created a hammock supporting the definite prosthesis. Follow up was at 2 weeks, 3 months, and 6 months. RESULTS Forty-one procedures were performed in 24 patients. The mean age was 45±12.08 years (range, 22 to 72 years). Patients' mean body mass index (BMI) was 26.79 kg/m2 (range, 19 to 35 kg/m2). One patient had diabetes and two smoked. One transient epidermolysis of the NAC occurred in each stage. No NAC or skin necrosis occurred; no implant had to be removed. CONCLUSIONS A two-stage mastopexy/reduction, simultaneously with preshaping of the implant pocket by tissue expansion and followed by a 3-month delayed secondary NSM with tissue expander-to-implant reconstruction is a safe technique in large ptotic breasts.

Abstract
OBJECTIVE Immediate direct-to-implant breast reconstruction with acellular dermal matrix (ADM) is the method of choice for many plastic surgeons and patients, but the use of ADM remains a controversial subject in the literature. This study aimed to investigate complications, reconstructive failure and possible risk factors in direct-to-implant breast reconstruction with ADM (primarily Strattice™). METHODS We retrospectively examined all patients undergoing immediate direct-to-implant breast reconstruction with ADM, during a five-year period (2014-2019) at a university clinic. Study outcomes were all complications and explantations. Complications were stratified within and after 6 months postoperatively and subcategorized by type of intervention. Explantations were subcategorized into loss of implant or salvage with immediate insertion of a tissue expander, the same or a new implant. RESULTS We included 154 patients and 232 breasts. Complications within 6 months per patient included hematoma (4%), seroma (8%), infection (9%), necrosis, wound dehiscence and delayed wound healing (19%). The total complication rate per patient was 34%. Explantation occurred in 20 patients (13%) of which 9 (6% of all) had implant loss. Preoperative radiotherapy was a significant predictor of explantation (adjusted OR 4.9, 95% confidence interval (CI), 1.0-23.5; p = 0.045), and smoking was also associated with risk of explantation, although only borderline significant (adjusted OR 4.0, 95% CI, 1.0-15.8; p = 0.050). CONCLUSION This study demonstrates acceptable rates of re-operations and implant loss compared to other studies but highlights the importance of proper patient selection with regards to risk factors to minimize complications.

Abstract
BACKGROUND Since the issue of breast implant-associated anaplastic large cell lymphoma, smooth breast implants tend to be the more preferred option in implant-based breast reconstructions, compared to its use previously. The most unfavorable aspect of smooth implants is lateral and inferior displacements, which are more common in patients who undergo breast reconstruction compared to augmentation mammoplasty. Hence, we introduce a prevention method for implant displacement using an acellular dermal matrix garter belt. METHODS This study is a retrospective review of patients who had undergone implant-based breast reconstruction between April 2019 and December 2020. Some patients who have highly possibility of implant displacement, had undergone the application of an ADM garter belt to prevent lateral or superior displacement. Implant displacement was assessed before and at least 6 months postoperatively. RESULTS A total of 155 IBR cases were recorded. ADM garter belts were applied in 27 patients (17.4%) who had a high tendency of implant displacement for several reasons, which could be classified into two categories: wide breast pocket (56%) and tight inferomedial breast pocket (44%). The intraoperative average distance of lateral slipping on patients' reconstructed breasts from the chest wall midline in supine position was 3.02 ± 0.81 cm and corrected to1.54 ± 0.69 cm at least 6 months postoperative follow-up. CONCLUSIONS We utilized an ADM strap as an internalized garter belt to minimize implant displacement. This ADM garter belt combined with capsuloplasty might be an effective way to prevent the displacement of smooth implants in the patients with a greater risk of implant displacement.

Abstract
BACKGROUND Capsular contracture is a well-recognized complication following prosthetic breast reconstruction. It has been the authors' observation that some patients undergoing breast reconstruction experience contracture specifically of the acellular dermal matrix placed at the time of their tissue expander insertion. The goal of the authors' study was to identify clinical and histologic findings associated with the development of acellular dermal matrix-associated contracture. METHODS The authors performed a retrospective cohort study of all patients undergoing bilateral implant-based breast reconstruction performed by the senior author (M.S.A.). Patients were excluded if they had radiation therapy to the breast. Patients with suspected acellular dermal matrix-associated contracture were identified by clinical photographs and review of operative notes. Histologic analysis was performed on specimens taken from two patients with acellular dermal matrix contracture. RESULTS The authors included a total of 46 patients (92 breasts), of which 19 breasts had suspected acellular dermal matrix-associated contracture. Acellular dermal matrix contracture was less common in direct-to-implant reconstruction (4.2 percent versus 26.5 percent; p = 0.020) and more common in breasts that had seromas (0 percent versus 15.8 percent; p = 0.001) or complications requiring early expander replacement. Contracted acellular dermal matrix had less vascularity and a lower collagen I-to-collagen III ratio, and was twice as thick as noncontracted acellular dermal matrix. CONCLUSIONS The authors have described a distinct phenomenon of acellular dermal matrix-associated contracture that occurs in a small subset of breasts where acellular dermal matrix is used. This merits further investigation. Future work will be required to better characterize the clinical factors that make acellular dermal matrix-associated contracture more likely to occur.

Abstract
Over 400,000 women in the United States alone will have breast implant surgery each year. Although capsular contracture represents the most common complication of breast implant surgery, surgeons continue to debate the precise etiology. General agreement exists concerning the inflammatory origin of capsular fibrosis, but the inciting events triggering the inflammatory cascade appear to be multifactorial, making it difficult to predict why one patient may develop capsular contracture while another will not. Accordingly, researchers have explored many different surgical, biomaterial, and medical therapies to address these multiple factors in an attempt to prevent and treat capsular contracture. In the current paper, we aim to inform the reader on the most up-to-date understanding of the pathophysiology, prevention, and treatment of capsular contracture.

Abstract
BACKGROUND Capsular contracture is a common complication of breast augmentation surgery and many techniques to prevent and treat it have been suggested with inconsistent or variably effective results. OBJECTIVES The aim of this paper was to describe a protocol for treating established capsular contracture after breast augmentation with a low recurrence rate. METHODS From January 2009 to December 2012, 79 previous bilateral breast augmentation patients presented for treatment of established capsular contracture. There were 135 breasts with capsular contracture: 56 were bilateral and 23 were unilateral. Ten patients opted for no treatment; 2 patients opted for implant removal. Twenty-four were treated with the ICES (implant exchange, capsulectomy, and possible exchange of site) protocol and 43 were treated with the SPICES (Strattice placement in the reconstructive position, implant exchange, capsulectomy, and possible exchange of site) protocol. RESULTS The 24 patients treated with the ICES protocol had a recurrent capsular contracture rate of 15%. The 43 patients treated with the SPICES protocol had a 2.7% recurrent capsular contracture incidence and an 2.7% complication rate. CONCLUSIONS Capsular contracture after breast augmentation, whether primary or recurrent, can be successfully treated with the SPICES protocol. LEVEL OF EVIDENCE: 4

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

Abstract
BACKGROUND Surgeons remain reluctant to perform nipple-sparing mastectomy (NSM) in large breasts due to a higher risk of necrosis. We performed a systematic review of the literature to evaluate indications, techniques, and outcomes in immediate or delayed breast reconstructions in large and/or ptotic breasts. METHODS The following search terms were used for both titles and key words: [NSM AND ("breast ptosis" OR "ptotic breast" OR "large breast" OR "breast hypertrophy" OR "gigantomastia")]. All forms of breast reconstruction in large and/or ptotic breasts from 1990 through September 1st 2018 reporting indications, techniques, and outcomes were included. RESULTS Thirty-one studies met the inclusion criteria, yielding 1128 NSMs (709 immediate and 419 delayed) in 629 patients for analysis. The overall complication rate was 29.08%. The mastectomy flap necrosis rate was 12%, the partial nipple-areola complex (NAC) necrosis 11%, and the complete NAC rate 11%. The overall complication rate in one-stage versus delayed reconstructions was 37.52% versus 14.8%. The incidence of necrosis in one-stage versus delayed reconstructions was 5.36% versus 2.15% for partial, 5.08% versus 0.48% for complete NAC necrosis, and 4.8% versus 1.43% for skin flap necrosis. CONCLUSIONS The majority of studies being small and retrospective as well as the large variation in outcomes indicates that we lack consensus on the timing of reconstruction or ideal technique. A noticeable difference in skin flap and NAC necrosis, however, is seen in the favor of NAC-delayed procedures. Randomized controlled trials are mandatory to prove this difference significantly.

Acellular Dermal Matrix Reduces Myofibroblast Presence in the Breast Capsule. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2213.

Abstract
Background Capsular contracture remains a common complication after implant-based breast reconstruction. Previous work has suggested that the use of acellular dermal matrix (ADM) reduces the rate of capsular contracture, though little is understood about the underlying mechanism. As myofibroblasts are believed to be the key cells implicated in contracture formation, we hypothesized that ADM would result in a reduction in periprosthetic myofibroblast concentration. Methods Five patients who underwent immediate prepectoral tissue expander placement with anterior ADM coverage and an inferior cuff were included. At the second stage, tissue samples were obtained of both ADM and capsule from each reconstructed breast. Samples were then prepared for hematoxylin and eosin staining and immunohistochemistry for myofibroblast identification (alpha smooth muscle actin and vimentin positive and desmin negative) and analysis. Experimental values are presented as mean ± SD unless otherwise stated. Statistical significance was determined using unpaired t test. Results Successful incorporation of ADM was noted in all cases. A significant reduction in myofibroblast concentration was noted in the ADM versus the capsule (P = 0.0018). This was paralleled by significantly thicker periprosthetic capsule formation overlying the formerly raw pectoralis major muscle, that is, not covered by ADM (P < 0.0001). Conclusions In the presence of ADM, there are significantly fewer myofibroblasts in breast capsules and thinner capsules on histology. Given the central role of myofibroblasts in the development of clinically significant capsular contracture, this study unmasks a possible mechanism for the protective effect of ADM with respect to capsular contracture development.

Abstract
INTRODUCTION Capsular contracture (CC) is the most common complication of breast implantation, with an incidence of nearly 50% in patients undergoing breast reconstruction with subsequent radiotherapy. Although the move toward submuscular (SM) device placement led to a decreased incidence of CC, subcutaneous (SQ) implantation has seen a resurgence. The purpose of this study was to use a rodent model of breast reconstruction with smooth silicone implants and delayed radiotherapy to assess the occurrence of CC in SQ versus SM implantation. METHODS Custom 2 mL smooth round silicone implants were placed bilaterally into 12 female Sprague Dawley rats that were randomized into 4 groups of 3, with each group differing by implantation plane (SQ vs SM) and irradiation status (irradiated vs nonirradiated). Rats from the SQ group received implants bilaterally underlying the skin on the flank. Rats in the SM groups received implants bilaterally under the latissimus dorsi muscle. Irradiated rats received 20 Gy localized to each implant on postoperative day 10. One rat from each group was imaged with a micro-computed tomography scanner at baseline and at explant 3 months later, whereupon capsules from all rats were examined histologically. RESULTS Rats in the SQ group showed evidence of contracture on gross examination and greater evidence of morphologic disruption per micro-computed tomography scan. There was no evidence of contracture or morphologic disruption in either SM group. Mean ± SD capsule thickness was 39.0 ± 9.0 μm in the SQ versus 37.6 ± 9.8 μm in the SM nonirradiated groups and 43.9 ± 14.9 μm in the SQ versus 34.3 ± 8.3 μm in the SM irradiated groups (all P > 0.05). CONCLUSIONS In a rodent model of smooth silicone breast implantation and delayed radiotherapy, although there did not appear to be differences in capsule thickness regardless of device placement plane, SQ implants demonstrated gross evidence of CC. These data indicate that capsule thickness is only part of a larger pathogenetic picture, which should take into consideration the contribution from all peri-implant tissue.

Abstract
BACKGROUND There have been many reported benefits of the usage of acellular dermal matrices (ADMs) in breast reconstruction. ADM reduces the need for rectus abdominis muscle and serratus anterior coverage by providing an inferolateral coverage of the implant/tissue expander. ADM can provide patients with a 1-staged reconstruction. This study was designed to look at the complication rates of 2 major hospitals in the United Kingdom. METHODS A large, 2-center retrospective cohort review of patients, who underwent implant-based breast reconstruction using Strattice (LifeCell Corp., Branchburg, N.J.) between March 2009 and November 2017, was performed. One-way analysis of variance was done to compare outcome significance between groups. Independent t test was performed to compare outcomes of 2 cohorts and regression analysis to include confounding factors using SPSS Statistics for Windows (Version 22.0. Armonk, NY: IBM Corp.). RESULTS A total of 450 and 400 breast reconstructions were carried out in University Hospital of South Manchester (UHSM) and Royal Free London Hospital (RFH), respectively. We recorded a total complication of 37.8% in RFH cohort and 28% in UHSM cohort. The seroma rate was 11.25% and 13.33% in the UHSM and RFH cohort, respectively. Other complications reported were major and minor infections, implant loss, skin necrosis, hematomas, and implant exposure. Multiple linear regression analysis reported that confounding factors affected certain outcomes. CONCLUSION Our 2-center complication rates were comparable to other articles. Results were comparable despite being in 2 different breast units in the United Kingdom.

Abstract
In craniofacial surgery, a wide spectrum of pathological conditions are usually treated. The aetiology of these could be congenital, traumatic, infective, post-tumor resection, postradiation, autoimmune, iatrogenic, or other miscellaneous conditions. The surgical approach for the procedures is usually via a coronal incision. In a large proportion of the patients, the frontal bone is removed to obtain intracranial access. The frontal bone is then replaced either in its original form or in a remodeled state. In congenital conditions the supraorbital bar and frontal bone is often also removed, remodeled, and replaced. One of the common late sequelae following craniofacial surgery is contour irregularities of the frontal region. These irregularities can vary in their extent. They are invariably palpable and often visible. Surgeons have attempted various methods to improve the contour irregularities. Despite these measures contour irregularities can still ensue. In the authors' unit, the authors have been using acellular dermal matrix in an attempt to diminish the contour irregularities in the frontal region following craniofacial reconstruction for craniosynostosis. This has been used in 35 patients undergoing craniosynostosis correction. Of the 35 patients, 12 were for plagiocephaly, 7 for brachycephaly, 10 for scaphocephaly, 4 for trigonocephaly, and 2 for combined coronal and metopic synostosis. The age of the patients ranged from 5 months to 12 years (mean 20.5 months). There were 21 males and 14 females. The follow-up ranged from 10 to 48 months (mean 23 months).

Abstract
Oncologic and reconstructive advancements in the management of patients with breast cancer and at high risk for breast cancer have led to improved outcomes and decreased patient morbidity. Traditional methods for prosthetic breast reconstructions have utilized total or partial muscle coverage of prosthetic devices. Although effective, placement of devices under the pectoralis major muscle can be associated with increased pain due to muscle spasm and animation deformities. Prepectoral prosthetic breast reconstruction has gained popularity in the plastic surgery community, and long-term outcomes have become available. This article will review the indications, technique, and current literature surrounding prepectoral prosthetic breast reconstruction.

Abstract
BACKGROUND Acellular dermal matrices have been proposed to decrease the incidence of capsular contracture in implant-based breast reconstructions. The authors have modified acellular dermal matrices with fenestrations to facilitate greater lower pole expansion and improve contour. The effect of fenestrations on the ability of matrices to suppress capsule formation, however, has not been examined. METHODS A retrospective review of all fenestrated acellular dermal matrix-assisted, implant-based breast reconstructions performed by the two senior authors, with a minimum of 1-year follow-up after permanent implant placement, was completed. Patient demographics, details of extirpative and reconstructive procedures, and complications were examined. Capsular contractures were scored according to the Baker grading scale and compared to those reported in the literature. RESULTS Thirty patients (50 breasts) underwent fenestrated acellular dermal matrix-assisted reconstruction, with mean follow-up times of 3.3 and 2.6 years after expander placement and implant exchange, respectively. Seven patients (23 percent) had a body mass index greater than 30 kg/m, three (10 percent) were active smokers, and six breasts (12 percent) were irradiated. Complications included one infection (2 percent), six cases (12 percent) of incisional superficial skin necrosis, and one (2 percent) tissue expander extrusion. Zero breasts had clinically significant Baker grade III/IV capsular contracture. The average Baker grade was 1.1. CONCLUSIONS Fenestrated acellular dermal matrices decrease capsular contracture to rates similar to what is seen with nonfenestrated matrices. Further research is necessary to determine whether this observation is a result of decreased need for inferolateral acellular dermal matrix coverage to achieve these effects or modified physical interaction of acellular dermal matrices with surrounding soft tissues.

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.

Lee J, Bae Y. Use of latissimus dorsi muscle onlay patch alternative to acellular dermal matrix in implant-based breast reconstruction. Gland Surg 2015; 4:270-6. [PMID: 26161312 DOI: 10.3978/j.issn.2227-684x.2015.01.07] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2014] [Accepted: 12/30/2014] [Indexed: 11/14/2022]
Abstract
BACKGROUND An acellular dermal matrix (ADM) is applied to release the surrounding muscles and prevent dislocation or rippling of the implant. We compared implant-based breast reconstruction using the latissimus dorsi (LD) muscle, referred to as an "LD muscle onlay patch," with using an ADM. METHOD A total of 56 patients (60 breasts) underwent nipple sparing mastectomy with implant-based breast reconstruction using an ADM or LD muscle onlay patch. Cosmetic outcomes were assessed 4 weeks after chemotherapy or radiotherapy, and statistical analyses were performed. RESULTS Mean surgical time and hospital stay were significantly longer in the LD muscle onlay patch group than the ADM group. However, there were no statistically significant differences between groups in postoperative complications. Cosmetic outcomes for breast symmetry and shape were higher in the LD muscle onlay patch group. CONCLUSIONS Implant-based breast reconstruction with an LD muscle onlay patch would be a feasible alternative to using an ADM.

Tissue Reinforcement in Implant-based Breast Reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2014; 2:e192. [PMID: 25426375 PMCID: PMC4236353 DOI: 10.1097/gox.0000000000000140] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2014] [Accepted: 04/29/2014] [Indexed: 11/26/2022]
Abstract
Background: Tissue reinforcement with allogeneic or xenogeneic acellular dermal matrices (ADMs) is increasingly used in single-stage (direct-to-implant) and 2-stage implant-based breast reconstruction following mastectomy. ADMs allow surgeons to control implant position and obviate the need for submuscular implant placement. Here, we review the benefits and risks of using ADMs in implant-based breast reconstruction based on available data. Methods: A comprehensive analysis of the literature with focus on recent publications was performed. Additional information regarding the proper use of ADMs was based on our institutional experience. Results: ADM use may improve definition of the lateral confines of the breast and lower pole projection. It may facilitate direct-to-implant procedures and improve aesthetic outcomes. The effect of ADMs on complication rates remains controversial. Known patient risk factors such as obesity, smoking, and radiotherapy should be considered during patient selection. For patients with healthy, well-vascularized skin envelopes, ADM-assisted direct-to- implant reconstruction is a safe and cost-effective alternative to 2-stage implant reconstruction, with low complication rates. ADMs may be used to treat capsular contracture, and limited available data further suggest the possibility that ADMs may reduce the risk of capsular contracture. Novel synthetic or biosynthetic tissue reinforcement devices with different physical and ease-of-use properties than ADMs are emerging options for reconstructive surgeons and patients who seek to avoid tissue products from human or mammalian cadavers. Conclusions: ADM-assisted implant-based breast reconstruction may improve aesthetic outcomes. However, appropriate patient selection, surgical technique, and postoperative management are critical for its success, including minimizing the risk of complications.

Porcine acellular dermal matrix (strattice) in primary and revision cosmetic breast surgery. Plast Reconstr Surg 2013; 131:1140-1148.

Abstract
BACKGROUND Although acellular dermal matrix materials have been in use for over a decade in primary and secondary breast reconstruction and in some cosmetic breast surgery, little has been published on the outcomes of these materials for cosmetic applications. METHODS A retrospective institutional review board-approved review was conducted of all patients who had a specific acellular dermal matrix, Strattice, used for cosmetic breast surgery performed by the senior author (S.L.S.). Patient demographics, indications, surgical findings, and postoperative course were collected and data analyzed using descriptive statistical tools. RESULTS Between 2008 and 2012, Strattice was used in 43 cosmetic breast operations (75 breasts) performed by the senior author (S.L.S.). Sixty-nine of the 75 breasts (92 percent) were revision operations. Indications included inferior pole support [39 breasts (52 percent)], fold malpositions [28 breasts (37 percent)], capsular contracture [25 breasts (33 percent)], and rippling/palpability [six breasts (8 percent)]. Three patients (six breasts) had Strattice placed during primary augmentation/mastopexy. Seventy-four of the 75 breasts (98.7 percent) had successfully achieved the indication for which the Strattice was placed; one breast (1.2 percent) had some degree of relapse. The global complication rate for all patients in this study is 5.3 percent-two breasts (2.7 percent) had postoperative malposition, one breast (1.2 percent) had bottoming out, and one breast (1.2 percent) developed an infection that resulted in temporary device explantation. CONCLUSIONS The use of Strattice is safe and may be helpful in the management of certain situations in cosmetic breast surgery, including needed lower pole support, capsular contracture, rippling, and implant malposition. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND Augmentation mammaplasty and augmentation mastopexy are associated with a substantial primary and secondary revision rate. Capsular contracture (CC), implant malposition, ptosis, asymmetry, and rippling are the main reasons for revisionary surgery in these patients. Traditional corrective techniques have not been completely reliable in preventing or treating these complications. Recently, acellular dermal matrices (ADM) have been used to assist with revisionary surgery with promising results. OBJECTIVE The authors review their 6-year experience using ADM for revisionary surgery in aesthetic patients and evaluate long-term outcomes with this approach. METHODS Patients who underwent revisionary breast augmentation or augmentation mastopexy with ADM in conjunction with standard techniques over a 6-year period between October 2005 and December 2011 were retrospectively reviewed. Only patients with at least 1 year of follow-up were included in the analysis. RESULTS A total of 197 revisions were performed (197 patients). Reasons for revision included CC (61.8%), implant malposition (31.2%), rippling (4.8%), ptosis (4.8%), implant exposure (1.6%), and breast wound (0.5%). The mean ± SD follow-up period was 3.1 ± 1.1 years (range, 0.1-6.1 years). The complication rate was 4.8%, including Baker grade III/IV CC (1.6%), infection (1.6%), implant malposition (0.5%), hematoma (0.5%), and seroma (0.5%). Most (98%) revisions were successful, with no recurrence of the presenting complaint. CONCLUSIONS The use of ADM in conjunction with standard techniques for the reinforcement of weak tissue in revision augmentation and augmentation mastopexy patients appears to be effective.
