Abstract
BACKGROUND Prepectoral breast reconstruction has become popularized with the concurrent use of acellular dermal matrix (ADM). The authors sought to compare 3-month postoperative complication rates and explantation rates for first-stage, tissue-expander-based, prepectoral breast reconstruction with and without the use of ADM. METHODS A single-institution retrospective chart review was performed to identify consecutive patients undergoing prepectoral tissue-expander-based breast reconstruction from August of 2020 to January of 2022. Chi-square tests were used to compare demographic categorical variables, and multiple variable regression models were used to identify variables associated with 3-month postoperative outcomes. RESULTS The authors enrolled 124 consecutive patients. Fifty-five patients (98 breasts) were included in the no-ADM cohort and 69 patients (98 breasts) were included in the ADM cohort. There were no statistically significant differences between the ADM and no-ADM cohorts with regard to 90-day postoperative outcomes. On multivariable analysis, there were no independent associations between seroma, hematoma, wound dehiscence, mastectomy skin flap necrosis, infection, unplanned return to the operating room, or explantation in the ADM and no-ADM groups after controlling for age, body mass index, history of diabetes, tobacco use, neoadjuvant chemotherapy, and postoperative radiotherapy. CONCLUSIONS The authors' results reveal no significant differences in odds of postoperative complications, unplanned return to the operating room, or explantation between the ADM and no-ADM cohorts. More studies are needed to evaluate the safety of prepectoral, tissue expander placement without ADM. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Impact of polyurethane versus acellular dermal matrix coating on prepectoral reconstruction outcomes: Interface does matter. J Plast Reconstr Aesthet Surg 2024; 91:15-23. [PMID: 38401273 DOI: 10.1016/j.bjps.2024.01.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 01/09/2024] [Accepted: 01/29/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Interfaces continue to be used in prepectoral breast reconstruction to refine breast appearance, but more clinical data are required to assess their effectiveness. This study compares the rates of capsular contracture, breast esthetics, and patient satisfaction between two commonly used interface materials, acellular dermal matrix (ADM) and polyurethane (PU) foam. METHODS A cross-sectional assessment was conducted on all patients who underwent prepectoral direct-to-implant reconstruction with an interface material between June 2018 and June 2022. We compared capsular contracture rates (assessed in-person), esthetic outcomes (evaluated by a three-member panel using a specially designed scale), and patient satisfaction (measured using the Breast-Q questionnaire) among the members of the interface groups. RESULTS Among the 79 reconstructed breasts (20 bilateral cases), 35 were reconstructed using ADM and 44 using PU implants. The ADM group had a significantly higher frequency of Baker III/IV capsular contracture compared with the PU group (14.3% vs. 0%, p = 0.014) and lower ratings from the panel in terms of capsular contracture (median 3.7 vs. 4.0, p < 0.001). PU reconstructions scored worse in implant visibility (median 2.3 vs. 3.3, p < 0.001) and rippling (median 3.0 vs. 3.7, p < 0.001). However, after appropriate adjustment for confounders, no significant differences in overall appearance and patient satisfaction were found. CONCLUSIONS ADM reconstructions are prone to capsular contracture with all their related esthetic issues, but PU implants have certain cosmetic flaws, such as implant visibility and malposition. Since each technique has its own limitations, neither the experienced surgeons nor patients exhibited a clear preference for either approach.

Abstract
BACKGROUND Postmastectomy radiotherapy (PMRT) is associated with altered cosmetic outcomes and higher complication rates in implant-based breast reconstruction (IBR). Conventional wisdom suggests that muscle coverage is somewhat protective against PMRT-related complications. In this study, the authors compared surgical outcomes in patients who underwent two-stage prepectoral versus subpectoral IBR in the setting of PMRT. METHODS The authors performed a retrospective cohort study of patients who underwent mastectomy and PMRT with two-stage IBR from 2016 to 2019. The primary outcome was breast-related complications, including device infection; the secondary outcome was device explantation. RESULTS The authors identified 179 reconstructions (101 prepectoral and 78 subpectoral) in 172 patients with a mean follow-up time of 39.7 ± 14.4 months. There were no differences between the prepectoral and subpectoral reconstructions in rates of breast-related complications (26.7% and 21.8%, respectively; P = 0.274), device infection (18.8% and 15.4%, respectively; P = 0.307), skin flap necrosis (5.0% and 1.3%, respectively; P = 0.232), or device explantation (20.8% and 14.1%, respectively; P = 0.117). In adjusted models, compared with prepectoral device placement, subpectoral device placement was not associated with a lower risk of breast-related complications [hazard ratio (HR), 0.75; 95% confidence interval (CI), 0.41 to 1.36], device infection (HR, 0.73; 95% CI, 0.35 to 1.49), or device explantation (HR, 0.58; 95% CI, 0.28 to 1.19). CONCLUSIONS Device placement plane was not predictive of complication rates in IBR in the setting of PMRT. Two-stage prepectoral IBR provides safe long-term outcomes with acceptable postoperative complication rates comparable to those with subpectoral IBR, even in the setting of PMRT.

Abstract
Background In this study, we established two rat models that mimic human submuscular and premuscular breast reconstruction. We analyzed the capsule formation according to surgical techniques and adjacent tissues, including the chest wall tissues, such as the ribs and acellular dermal matrices (ADMs) that come in contact with silicone implants. Methods This study consisted of experiments on 12 Sprague-Dawley rats that underwent implant reconstruction using ADM. They were divided into two groups: rats that underwent dual-plane implantation (n = 6; group 1) and those that underwent premuscular implant insertion (n = 6; group 2). All rats were irradiated with 35 Gy of fractionated radiation. Three months after surgery, the histology and immunochemistry of the capsule tissues of the ADM, muscle, and chest wall were analyzed. Results Overall capsule thickness was thicker in group 1. Based on the tissue in contact with the silicone implant, ADM had a thinner capsule, less inflammation, less fibrosis, and less vascularization than the muscle and chest wall tissues. Conclusions This study described two rat models of clinically relevant implant-based breast reconstruction using a submuscular and premuscular plane, ADM, and irradiation. Overall, the premuscular implantation rat model was associated with a thinner capsule. The ADM in contact with the silicone implant, even after irradiation, had superior protection from radiation compared with the other tissues.

Abstract
Women with BRCA gene mutations have a higher lifetime risk of developing breast cancer. Furthermore, cancer is usually diagnosed at a younger age compared to the wild-type counterpart. Strategies for risk management include intensive surveillance or risk-reducing mastectomy. The latter provides a significant reduction of the risk of developing breast cancer, simultaneously ensuring a natural breast appearance due to the preservation of the skin envelope and the nipple-areola complex. Implant-based breast reconstruction is the most common technique after risk-reducing surgery and can be achieved with either a submuscular or a prepectoral approach, in one or multiple stages. This study analyzes the outcomes of the different reconstructive techniques through a retrospective review on 46 breasts of a consecutive, single-center case series. Data analysis was carried out with EpiInfo version 7.2. Results of this study show no significant differences in postoperative complications between two-stage tissue expander/implant reconstruction and direct-to-implant (DTI) reconstruction, with DTI having superior aesthetic outcomes, especially in the prepectoral subgroup. In our experience, the DTI prepectoral approach has proven to be a safe and less time-consuming alternative to the submuscular two-stage technique, providing a pleasant reconstructed breast and overcoming the drawbacks of subpectoral implant placement.

Abstract
Prepectoral breast reconstruction has gained popularity due to numerous benefits in properly selected patients. Compared with subpectoral implant reconstruction, prepectoral reconstruction offers preservation of the pectoralis major muscle in its native position, resulting in decreased pain, no animation deformity, and improved arm range of motion/strength. Although prepectoral reconstruction is safe and effective, the implant sits closer to the mastectomy skin flap. Acellular dermal matrices play a critical role, allowing for precise control of the breast envelope and providing long-term implant support. Careful patient selection and intraoperative mastectomy flap evaluation are critical to obtaining optimal results with prepectoral breast reconstruction.

Abstract
BACKGROUND Capsular contracture (CC) is a common long-term complication following prosthetic-based breast reconstruction (PBBR). Seven cases of CC following mRNA vaccination for coronavirus 2019 (COVID-19) are reported in the literature. OBJECTIVES The aim of this study was to determine whether receiving the COVID-19 vaccine was associated with CC development following PBBR. METHODS A retrospective, multicenter nested case-control study was performed from January 2014 to July 2022 of adult female patients who underwent PBBR with acellular dermal matrix placement. Cases of CC were selected if no adjuvant radiation was received and they presented for follow-up between December 2020 and July 2022. Controls included patients who met inclusion criteria but who did not experience CC in either breast. Patient demographics, breast cancer characteristics, reconstructive surgery details, postoperative complications, and COVID-19 exposure details were analyzed and correlated with CC development. RESULTS Of a total of 230 patients (393 breasts) who received PBBR, 85 patients (135 breasts) met inclusion criteria, of whom 12 patients (19 breasts) developed CC and 73 patients (116 breasts) did not. At the time of median follow-up of 18.1 months (n = 85; interquartile range, 12.2-33.6 months), no statistically significant differences were observed between the short- or long-term complications in cases or controls. There were no significant differences in COVID-19 vaccination status, number of vaccine doses, or vaccination type between cases and controls. Vaccination status was not associated with greater odds of CC development (odds ratio, 1.44; 95% CI, 0.42-5.37; P > .05). CONCLUSIONS Direct association between CC and COVID-19 vaccination is difficult to prove. Given the known risk of severe COVID-19 infection among immunocompromised patients, those with breast cancer who undergo PBBR should be properly counseled on the benefits and risks of vaccination.

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
INTRODUCTION The extracellular matrix (ECM) plays an integral role in wound healing. It provides both structure and growth factors that allow for the organised cell proliferation. Large or complex tissue defects may compromise host ECM, creating an environment that is unfavourable for the recovery of anatomical function and appearance. Acellular dermal matrices (ADMs) have been developed from a variety of sources, including human (HADM), porcine (PADM) and bovine (BADM), with multiple different processing protocols. The objective of this report is to provide an overview of current literature assessing the clinical utility of ADMs across a broad spectrum of applications. METHODS PubMed, MEDLINE, EMBASE, Scopus, Cochrane and Web of Science were searched using keywords 'acellular dermal matrix', 'acellular dermal matrices' and brand names for commercially available ADMs. Our search was limited to English language articles published from 1999 to 2020 and focused on clinical data. RESULTS A total of 2443 records underwent screening. After removing non-clinical studies and correspondence, 222 were assessed for eligibility. Of these, 170 were included in our synthesis of the literature. While the earliest ADMs were used in severe burn injuries, usage has expanded to a number of surgical subspecialties and procedures, including orthopaedic surgery (e.g. tendon and ligament reconstructions), otolaryngology, oral surgery (e.g. treating gingival recession), abdominal wall surgery (e.g. hernia repair), plastic surgery (e.g. breast reconstruction and penile augmentation), and chronic wounds (e.g. diabetic ulcers). CONCLUSION Our understanding of ADM's clinical utility continues to evolve. More research is needed to determine which ADM has the best outcomes for each clinical scenario. LAY SUMMARY Large or complex wounds present unique reconstructive and healing challenges. In normal healing, the extracellular matrix (ECM) provides both structural and growth factors that allow tissue to regenerate in an organised fashion to close the wound. In difficult or large soft-tissue defects, however, the ECM is often compromised. Acellular dermal matrix (ADM) products have been developed to mimic the benefits of host ECM, allowing for improved outcomes in a variety of clinical scenarios. This review summarises the current clinical evidence regarding commercially available ADMs in a wide variety of clinical contexts.

Abstract
BACKGROUND With the increased use of acellular dermal matrix (ADM) in breast reconstruction, the number of available materials has increased. There is a relative paucity of high-quality outcomes data for use of different ADMs. OBJECTIVES The goal of this study was to compare the outcomes between a human (HADM) and a bovine ADM (BADM) in implant-based breast reconstruction. METHODS A prospective, single-blinded, randomized controlled trial was conducted to evaluate differences in outcomes between HADM and BADM for patients undergoing immediate tissue expander breast reconstruction. Patients with prior radiation to the index breast were excluded. Patient and surgical characteristics were collected and analyzed. RESULTS From April 2011 to June 2016, a total of 90 patients were randomized to a mesh group, with 68 patients (HADM, 36 patients/55 breasts; BADM, 32 patients/48 breasts) included in the final analysis. Baseline characteristics were similar between the 2 groups. No significant differences in overall complication rates were identified between HADM (n = 14, 25%) and BADM (n = 13, 27%) (P = 0.85). Similar trends were identified for major complications and complications requiring reoperation. Tissue expander loss was identified in 7% of HADM patients (n = 4) and 17% of BADM patients (n = 8) (P = 0.14). CONCLUSIONS Similar complication and implant loss rates were found among patients undergoing immediate tissue expander breast reconstruction with HADM or BADM. Regardless of what material is used, careful patient selection and counseling, and cost consideration, help to improve outcomes and sustainability in immediate breast reconstruction.

Abstract
PURPOSE Capsular contracture (CC) is a troublesome complication after breast surgery with breast implants, and the risk increases in breast cancer patients after radiotherapy. Studies investigating leukotriene antagonists (eg, montelukast, zafirlukast) found that the acellular dermal matrix (ADM) can help prevent CC. We aimed to compare the effects of ADM and montelukast on CC after irradiation. METHODS Eighteen New Zealand white rabbits were randomly divided into 3 groups of 6 each. Miniature cohesive gel implants were inserted into the pocket under the latissimus dorsi muscle. The lateral part was uncovered by the latissimus dorsi muscle. Six animals were included in the control group. In experimental group A (EG-A) (n = 6), the site was partially wrapped with ADM but not covered with muscle. Montelukast (Singulair, 0.2 mg/kg) was administered in experimental group B (EG-B) (n = 6) daily. Groups were irradiated at postoperative day 21 with Co-60 γ rays (25 Gy, single fraction) at the peri-implant area. Rabbits were sacrificed 12 weeks after surgery; implants with peri-implant capsule were harvested. Capsule thickness, collagen pattern, myofibroblast, and transforming growth factor (TGF) β1/2 levels in the peri-implant capsule were evaluated. RESULTS On histological evaluation, the capsule was thinner on the lateral aspect (covered with ADM) in EG-A (P = 0.004) and the entire capsule in EG-B (P = 0.004) than in the control group. However, there was no significant difference between EG-A and EG-B (P = 0.073). The collagen distribution pattern was more parallel with low density in the lateral capsular aspect in EG-A, but in the entire capsule in EG-B. The myofibroblast amount (EG-A, P = 0.031; EG-B, P = 0.016) and levels of TGF-β1 and TGF-β2 were reduced in the experimental groups (TGF-β1, EG-A, P = 0.019; TGF-β1, EG-B, P = 0.045; TGF-β2, EG-A, P = 0.018; TGF-β2, EG-B, P = 0.022). There was no significant difference between EG-A and EG-B (myofibroblast, P = 0.201; TGF-β1, P = 0.665; TGF-β2, P = 0.665). CONCLUSIONS Acellular dermal matrix and montelukast have a prophylactic effect for CC even when the breast is irradiated. There was no significant difference between ADM and montelukast in preventing capsular formation. The difference is that ADM will only have the effect of covering the capsular formation with ADM and montelukast can cause systemic effects or complications.

Abstract
PURPOSE Reconstruction of the defects and recovery of the laryngopharyngeal function after resection of hypopharyngeal carcinoma are crucial for patients to promote the rate of survival and the quality of life. We launched this study to explore the advantages and limitations of acellular dermal matrix applied in the reconstruction of the defects after hypopharyngeal carcinoma surgery. MATERIALS AND METHODS Collected the clinical and pathological data of patients with hypopharyngeal carcinoma, divided them into 2 groups according to the repair materials used (pectoralis major myocutaneous flap or acellular dermal matrix). The clinical data and postoperative complications were analyzed and compared. RESULTS No matter whether the pectoralis major myocutaneous flap or acellular dermal matrix was used to repair hypopharyngeal cancer resection defects, the postoperative complications, especially the pharyngeal fistula rate, were not significantly different. The postoperative drainage volume of patients with acellular dermal matrix was less than that of patients with pectoralis major myocutaneous flap. CONCLUSIONS Acellular dermal matrix is a safe and effective biomedical material for hypopharyngeal cancer operation defects repair and pharyngeal function reconstruction, which can simplify the operation process, reduce the postoperative drainage volume, and decrease the risk of wound infection or pharyngeal fistula.

Abstract
Prepectoral breast reconstruction after mastectomy is a more commonly performed technique in recent years due to its numerous advantages over subpectoral breast reconstruction. This study reviews the current state of clinical outcomes for patients undergoing postmastectomy radiation therapy (PMRT) after prepectoral breast reconstruction. A comprehensive search of the literature was performed using the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines to identify all relevant studies. Outcome measures included demographics, mean follow-up, and complication measures. Three studies for a total of 175 breasts were identified. Average age was 49.3 years and BMI was 27.7 kg/m2. Mean follow up was 18.1 months. A total of 3 (1.7%) hematomas and 4 (2%) seromas were reported. Surgical site infection was the most common complication reported with an overall reported 32 breasts with infections (18%). A total of 9 (5.1%) cases of wound dehiscence were reported. Mastectomy flap necrosis was found in 10 (5.7%) breasts. A total of 22 (12.6%) tissue expanders or implants required explantation. The review of the literature suggests that prepectoral breast reconstruction with acellular dermal matrices in the setting of post mastectomy radiation therapy is a safe and successful surgical option resulting in excellent clinical outcomes. Furthermore, there may be a reduction of capsular contracture and implant migration in this setting, relative to traditional submuscular techniques with PMRT.

Abstract
Implant-based breast reconstruction is a safe and effective option associated with high patient satisfaction. Techniques have evolved significantly over the past several decades, characterized mostly by a reduction in the number of stages and time required to complete reconstruction, with maximal preservation of native breast elements. Nevertheless, both old and new techniques of implant-based breast reconstruction have a role depending on the specific clinical scenario, and thus plastic surgeons should be well versed in the full spectrum of options. This article reviews the key considerations underlying decision-making in implant-based breast reconstruction and the most effective techniques, with a focus on optimizing safety and efficiency.

Abstract
Since the advent of the vascular anastomosis by Alexis Carrel in the early 20th century, the repair and replacement of blood vessels have been key to treating acute injuries, as well as chronic atherosclerotic disease. Arteries serve diverse mechanical and biological functions, such as conducting blood to tissues, interacting with the coagulation system, and modulating resistance to blood flow. Early approaches for arterial replacement used artificial materials, which were supplanted by polymer fabrics in recent decades. With recent advances in the engineering of connective tissues, including arteries, we are on the cusp of seeing engineered human arteries become mainstays of surgical therapy for vascular disease. Progress in our understanding of physiology, cell biology, and biomanufacturing over the past several decades has made these advances possible.

Abstract
BACKGROUND Capsular contracture causes pain, poor cosmesis, and reoperations. This study analyzes its incidence and risk factors in a more modern treatment era. METHODS Patients undergoing mastectomy with implant reconstruction from 2010 to 18 were reviewed. Univariate and multivariate analysis evaluated rates and risk factors for capsular contracture. RESULTS Among 451 patients, the majority underwent nipple-sparing mastectomy (262, 58.1%) with one-stage reconstruction (283, 62.7%) utilizing subpectoral implants (353, 77.4%) and acellular dermal matrix (354, 78.5%). Overall capsular contracture incidence was 9.8%; the rate after post-mastectomy radiation therapy (PMRT) was 18.7%, and 7.5% for patients without PMRT. Significant factors included neoadjuvant chemotherapy (P = 0.006), hematoma (P = 0.047), and PMRT (P = 0.001). Multivariate analysis showed that PMRT increased risk of capsular contracture (OR = 3.12, 95% CI 1.55-6.26, P = 0.001), and adjuvant chemotherapy was protective (OR = 0.289, 95% CI 0.114-0.731, P = 0.01). CONCLUSIONS Incidence of capsular contracture is lower than previously reported. Advancing therapeutic techniques may reduce the risk of this complication.

Abstract
BACKGROUND A large number of clinical studies have suggested that acellular dermal matrix (ADM) can decrease the incidence of capsular contracture in implant-based breast reconstruction. Yet, there is currently no high-level epidemiological evidence to prove this. The goal of this meta-analysis was to clarify the efficacy of ADM in capsular contracture, and provide a reference value for plastic surgeons. METHODS We systematically performed a search on PubMed, EMBASE, and the Cochrane Library to identify eligible studies from inception up to October 1, 2019. A random-effects model was used to obtain a pooled incidence rate. We conducted subgroup analysis according to geographic region, type of ADM, body mass index (BMI), duration of follow-up, and proportion of participants who have received radiotherapy. RESULTS A total of 18 studies involving 2941 cases were included. Overall, the pooled incidence rate of capsular contracture was 2.4% (95% CI 1.2-3.9%). The results from subgroup analyses indicated an even lower incidence in North America (1.6%, 95% CI 0.5-3.3%) and in human-derived ADM (HADM) (1.2%, 95% CI 0.2-3.0%). In addition, the results showed that the patients with BMI < 24, or who have received radiotherapy, were more prone to capsular contracture. CONCLUSION The application of ADM can effectively reduce the incidence of capsular contracture in implant-based breast reconstruction. And we infer that it might also apply to breast augmentation. However, additional high-quality trials are warranted to corroborate the findings of this meta-analysis.

Povidone-iodine Does Not Affect Acellular Dermal Matrix Integration in Patients Undergoing 2-staged, Prepectoral, Breast Reconstructive Surgery. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e2758. [PMID: 32440426 PMCID: PMC7209843 DOI: 10.1097/gox.0000000000002758] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2019] [Accepted: 02/11/2020] [Indexed: 11/25/2022]
Abstract
Background: Povidone-iodine has been traditionally used as an antimicrobial agent to irrigate the breast pocket and rinse the prosthesis before placement in the pocket. Use of povidone-iodine with breast implants was banned from 2000 to 2017. During this period, acellular dermal matrix (ADM) was introduced to breast surgery. In nonclinical studies, povidone-iodine can impair collagen synthesis and kill fibroblasts. Cellular repopulation was critical for ADM integration. Whether povidone-iodine impacts ADM integration was unknown. Methods: Patients who underwent immediate, prepectoral, 2-staged breast reconstruction were included in this retrospective study. Study population was divided into povidone-iodine–treated patients and triple-antibiotic–treated patients. The breast pockets were rinsed with the antimicrobial agent, and the prostheses and ADMs were presoaked in the agent perioperatively. At implant exchange, the extent of ADM integration was clinically assessed. ADM integration was defined as >25% of matrix vascularization. ADM integration and postoperative complications were compared between the groups. Results: A total of 111 patients (257 reconstructions) were included—58 patients (111 reconstructions) were exposed to povidone-iodine and 53 patients (97 reconstructions) to triple-antibiotic solution. ADM integration was noted in 97% of breasts in each group. Integrated matrices appeared healthy, had no signs of foreign body reaction, and demonstrated punctate bleeding. Complications did not differ between the groups, including the rate of infections, seroma, and expander loss. Conclusion: Irrigation of the breast pocket and presoaking of the prosthesis and ADM with povidone-iodine appear to have no adverse consequences on clinical outcomes and did not impede matrix integration.

Abstract
Background
Breast cancer is the most common cancer affecting women in Germany. Despite breast-conserving therapy (BCT) being carried out in almost 70% of cases, a high number of women still require complete mastectomy. Prophylactic mastectomy is also indicated for women with a BRCA 1/2 gene mutation. In addition to implant-based heterologous breast reconstruction, autologous breast reconstruction using a DIEP flap has been found to be beneficial, particularly for patients who had prior radiotherapy. This study aims to show that DIEP flap reconstruction surgery is the method of choice for autologous breast reconstruction with a low rate of complications.
Patients and Methods
Autologous breast reconstruction using a DIEP flap was performed in 1124 patients between July 2004 and December 2014. Retrospective study criteria included potential risk factors such as age, BMI, smoking, chemotherapy and/or radiotherapy, and comorbidities as well as outcome parameters such as postoperative complications. Outcomes were evaluated with a mean follow-up of 24 months.
Results
A total of 1124 patients underwent 1274 free DIEP flap breast reconstructions, of which 150 were bilateral reconstructions. The primary indication was previous mastectomy in 785 cases, followed by prior implant-based reconstruction in 265 cases. The total flap loss rate was 0.6%. Postoperative surgical revision for abdominal wall hernia was required in 0.2% of cases. The group with a higher BMI and the group of smokers had significantly higher complication rates. Elderly patients (> 65 years), patients who had undergone chemo-/radiotherapy and patients with diabetes did not have higher complication rates.
Conclusion
DIEP flap surgery is an excellent option for autologous breast reconstruction, with a low rate of donor site morbidity and low complication rates. DIEP flap surgery carried out in a specialised interdisciplinary breast centre in a standardised clinical setting after prior careful patient selection to take account of risk factors such as high BMI and smoking is a reliable method with a low complication rate and satisfactory long-term reconstruction results.

Abstract
Latissimus dorsi myocutaneous flap (LDMF) with tissue expander provides excellent results in breast reconstruction. Acellular dermal matrix (ADM) has been used in expander-based reconstruction (EBR) with good results. This study assesses how ADM compares to LDMF in EBR. Methods The cohorts comprised 124 patients (218 breasts) who had EBR using ADM between 2006 and 2012, and 242 patients (266 breasts) who had EBR using LDMF between 1994 and 2012. Postoperative complications, reoperations, Breast-Q scores, and objectively assessed aesthetic outcomes were compared. Results Median age was 55 years for both ADM (range 23-84) and LDMF (range 26-88) groups. No statistically significant differences were noted between the groups in the rates of major postoperative complications (P > 0.3). Forty-nine of the 218 (22.5%) in the ADM group and 67 of 266 (25.2%) in the LDMF group had a total of 63 and 84 reoperations, respectively (P = 0.52), with no significant differences in the reoperations rate (P > 0.3). No significant differences were observed in the Breast-Q scores. Some categorical differences were noted in the aesthetic outcomes; however, the difference between the overall outcomes was not significant (P = 0.54). Conclusion Our study revealed no statistically significant differences in the complications or reoperation rates, patient satisfaction, or overall aesthetic outcomes when comparing the use of ADM to LDMF in EBR. In conclusion, this study supports the hypothesis that ADM performs as well as LDMF in EBR.

The aim of this study was to compare inflammatory response and synovial metaplasia in implant-based immediate breast reconstruction with a biological mesh (Veritas®) with that of a synthetic mesh (TIGR® Matrix Surgical Mesh). We hypothesize that the inflammatory response and formation of synovial metaplasia might be different and the rate of capsular contracture therefore different. The patients were recruited from the Gothenburg TIGR®/Veritas® Study (ClinicalTrials.Gov identifier NCT02985073). All referrals for bilateral immediate breast reconstruction were assessed for inclusions. During the operation, the patients were randomized to which sides the biological and the synthetic mesh were going to be applied. During the implant exchange biopsies were taken. Biopsies were taken from 30 breasts in 15 patients. There seem to be more myofibroblast and neovascularization in the biological meshes than in the synthetic and the collagen fibers seem to be aligned in an irregular pattern with both parallel and vertical fibers. In the synthetic meshes, there were more giant cells and foreign body reaction and the collagen fibers were loosely and well aligned, oriented parallel to the surface of the implant. Synovial metaplasia was seen in the majority of both the biological and the synthetic meshes. The histological patterns in early capsules from biological and synthetic meshes vary considerably. Nonetheless, it is unknown what role different cell types have in capsular formation in the long run and there was no difference in clinical capsular contracture at the clinical follow-up in this study.

Abstract
Modern advances in tissue engineering have transformed the plastic surgeon's management strategies across a wide variety of applications. Comprehension of the fundamentals of biologic constructs is critical to navigating the available armamentarium. It is essential that plastic surgeons become familiar with some of the existing methods for utilizing biologics as well as the advantages and limitations to their use. In this article, the authors describe the basic science of biologics with a focus on acellular dermal matrices (ADMs), and review the recent evidence behind their use for a variety of reconstructive and aesthetic purposes. The review is organized by system and examines the common indications, techniques, and outcomes pertaining to the application of ADMs in select anatomic areas. The final section briefly considers possible future directions for using biologics in plastic and reconstructive surgery.

Abstract
Human acellular dermal matrix (ADM) can augment prepectoral prosthetic-based direct-to-implant breast reconstruction by providing an additional soft-tissue layer between breast implant and skin, as well as to reinforce the inframammary fold and breast pocket. Utilizing ADM in this way has helped reduce rates of implant rippling, capsular contracture, and implant extrusion. Difficulty in securing ADM-wrapped implants has caused many surgeons to improvise techniques for secure implantation. Here, we describe a simple technique for creating suture tabs within the ADM for efficient fixation of the ADM-implant construct to the chest wall.

Abstract
BACKGROUND Although multiple acellular dermal matrix sources exist, it is unclear how its processing impacts complication rates. The authors compared complications between two preparations of human cadaveric acellular dermal matrix (freeze dried and ready-to-use) in immediate tissue expander breast reconstruction to analyze the effect of processing on complications. METHODS The authors retrospectively reviewed all alloplastic breast reconstructions with freeze-dried or ready-to-use human acellular dermal matrices between 2006 and 2016. The primary outcome measure was surgical-site occurrence defined as seroma, skin dehiscence, surgical-site infection, or reconstruction failure. The two groups were compared before and after propensity score matching. RESULTS The authors included 988 reconstructions (freeze-dried, 53.8 percent; ready-to-use, 46.2 percent). Analysis of 384 propensity score-matched pairs demonstrated a slightly higher rate of surgical-site occurrence (21.4 percent versus 16.7 percent; p = 0.10) and surgical-site infection (9.6 percent versus 7.8 percent; p = 0.13) in the freeze-dried group than in the ready-to-use group, but the difference was not significant. However, failure was significantly higher for the freeze-dried versus ready-to-use group (7.8 percent versus 4.4 percent; p = 0.050). CONCLUSIONS This is the largest study comparing the outcomes of alloplastic breast reconstruction using human acellular dermal matrix materials prepared by different methods. The authors demonstrated higher early complications with aseptic, freeze-dried matrix than with sterile ready-to-use matrix; reconstructive failure was the only outcome to achieve statistical significance. The authors conclude that acellular dermal matrix preparation has an independent impact on patient outcomes in their comparison of one company's product.

Abstract
Prosthetic breast reconstruction is the most common method of reconstruction offered to women following mastectomy. Prepectoral breast reconstruction has recently reemerged as an alternative technique to the partial and total muscle coverage methods. Though this technique has been demonstrated to be safe and effective in the recent published literature, many surgeons have been hesitant to adopt it out of fear of incurring the same complications associated with subcutaneous reconstructions of the past. However, recent advancements in plastic surgery including the use of acellular dermal matrices, autologous fat grafting, and improved breast implants and improved mastectomy techniques have enabled plastic surgeons to revisit the prepectoral space. In this review, the authors describe the evolution of prosthetic-based breast reconstruction from subcutaneous to prepectoral and review outcomes.

Abstract
BACKGROUND Capsular contracture is one of the most common complications of expander-implant breast reconstruction. Recently, clinical reports have shown that use of an acellular dermal matrix (ADM) to cover breast implants decreases incidence of capsular contracture, but the underlying mechanism is unclear. Here, we examine how ADM reduces capsular formation in expander-implant breast reconstruction and identify cellular and molecular mechanisms of ADM-mediated reduction of capsular contracture in nonirradiated and irradiated patients. METHODS Thirty patients who underwent immediate two-stage implant-based breast reconstruction were included; 15 received radiotherapy. While the tissue expander was changed to permanent silicone implant, biopsies of the subpectoral capsule and ADM capsule were performed. Capsule thickness, immunohistochemistry of α-smooth muscle actin (αSMA), vimentin, CD31, F4/80 expression, αSMA and CD31 coexpression, and relative gene expression levels of transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF)-B were investigated. RESULTS Irradiated submuscular capsules were thicker than nonirradiated submuscular capsules, but the thickness of ADM capsules did not significantly differ between nonirradiated and irradiated groups. Levels of myofibroblasts, fibroblasts, vascularity, EndoMT, and macrophages were significantly lower in ADM capsules than in submuscular capsules. With the exception of EndoMT, all others were increased in irradiated submuscular capsules compared with nonirradiated submuscular capsule, while none significantly differed between nonirradiated and irradiated ADM capsules. CONCLUSIONS Use of ADM reduced myofibroblasts, vascularity, fibroblasts, and EndoMT in capsule tissues. Moreover, ADM use decreased macrophages, a key regulator of tissue fibrosis, as well as TGF-β1 and PDGF-B expression. We hope that these results provide basic concepts important for prevention of capsular contracture.

Abstract
BACKGROUND Shifting preference for implant-based breast reconstruction has resulted in an increased use of acellular dermal matrix (ADM) in tissue-expander breast reconstruction. The benefits afforded by ADM must be weighed against a potential increased risk for postoperative complications. Dermal autograft-assisted breast reconstruction using autograft harvest from the lower abdomen has been shown to result in equivalent aesthetics and patient satisfaction compared with ADM at a lower cost, with fewer complications. The purpose of this study was to review a series of patients who underwent bilateral mastectomy and immediate dermal autograft-assisted tissue expander (TE) breast reconstruction using the non-cancerous breast as a donor site, comparing the outcomes with a concurrent cohort of patients undergoing ADM-assisted reconstruction to determine the relative safety, cost, and effectiveness of the 2 procedures. METHODS The study population included all patients who underwent dermal autograft-assisted TE breast reconstruction, using the contralateral cancer-free breast as the source of dermal autograft, between 2010 and 2015. The ADM cohort consisted of patients who underwent bilateral mastectomy and immediate ADM-assisted TE breast reconstruction during the same period. Univariate analysis was performed for demographic data, complications, operative cost, and operative time. Data were compared using the Wilcoxon rank sum test for nonparametric data and χ analyses for continuous and categorical variables. Significance was defined as P value less than 0.05. RESULTS Seventeen patients received dermal autograft using the non-cancerous breast donor site. Twenty-seven patients who underwent ADM-assisted reconstruction during the same period were identified. Significantly higher cost was demonstrated between groups (ADM, US $9999.87; autograft, US $3924.19; P < 0.0001). No significance difference existed operative time (autograft, 97 min; ADM, 120 min). No difference was found in wound healing complications (ADM, 14.8%; autograft, 23.53%; P = 0.47). No significant difference was found in major complications (ADM, 26%; autograft, 17.65%; P = 0.52) or infectious complications (ADM, 26%; autograft, 17.65%; P = 0.52). CONCLUSIONS Dermal autograft-assisted breast reconstruction using the contralateral non-cancerous breast as the source of dermal autograft harvest represents a lower cost alternative to ADM without increased risk of postoperative complications.

Abstract
BACKGROUND Breast augmentation is one of the most commonly performed aesthetic surgery procedures worldwide. Bacterial contamination is of paramount concern due to its role in biofilm formation and capsular contracture. Plastic surgeons have adopted a variety of perioperative interventions in efforts to reduce implant contamination, however definitive evidence supporting these practices is lacking. OBJECTIVE The goal of this study was to assess current practice patterns aimed at reducing implant-related infections in breast augmentation and comparing them to current evidence-based medicine recommendations. METHODS A 20-question survey assessing practices aimed at preventing breast implant associated infections was generated and distributed via SurveyMonkey to members of the American Society of Plastic Surgery whose electronic mail addresses were listed on the American Society of Plastic Surgery member website in April 2015. RESULTS A total of 253 responses were received from the survey. Of the respondents, 81% were in private practice. Respondents averaged 21 ± 9 years in practice, and 69 ± 111 breast augmentations performed per year. A majority of surgeons used Chlorhexidine to prepare the surgical site (45%) and triple antibiotic solution both as a soak for the implant before placement (40%) as well as for implant pocket irrigation (47%). A no-touch technique using the Keller Funnel was adopted by 42% of surgeons. Regarding antibiotic use in the postoperative period, first-generation cephalosporins were used by the majority of respondents (79%), and the most common duration was for 4 to 6 days (45%). CONCLUSIONS Although there is heterogeneity in specific aspects of antimicrobial prophylaxis during breast augmentation, there is a clear trend toward practice modification geared towards preventing bacterial contamination in breast augmentation. Surgeons may benefit from high-level studies designed to create standardized evidence-based practice guidelines.

Abstract
The use of novel devices such as acellular dermal matrices (ADMs) to support the lower pole in implant-based breast reconstructions (IBBRs) has been described as one of the most important advances in breast reconstructive surgery following mastectomy. However, the majority of outcomes studies focus primarily on providing evidence for the rates of short-term complications associated with their use, as opposed to their reported benefits. Given the high costs associated with using ADMs, together with an increasing number of alternative, cheaper synthetic products entering the market, it is important to clarify whether their use is actually justified and whether the alternative products offer equivalent or superior outcomes. The purpose of this article is to present a comprehensive and updated review of the evidence for the benefits of using different products for lower pole support (LPS) in IBBR compared to reconstructions without. A secondary aim was to determine if there is any evidence to support the use of one product over another.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Assess common clinical problems in the secondary breast augmentation patient. 2. Describe a treatment plan to correct the most common complications of breast augmentation. 3. Provide surgical and nonsurgical options for managing complications of breast augmentation. 4. Decrease the incidence of future complications through accurate assessment, preoperative planning, and precise surgical technique. SUMMARY Breast augmentation has been increasing steadily in popularity over the past three decades. Many of these patients present with secondary problems or complications following their primary breast augmentation. Two of the most common complications are capsular contracture and implant malposition. Familiarity and comfort with the assessment and management of these complications is necessary for all plastic surgeons. An up-to-date understanding of current devices and techniques may decrease the need to manage future complications from the current cohort of breast augmentation patients.

Abstract
OBJECTIVE Skin-sparing mastectomy (SSM) with immediate heterologous reconstruction is a safe oncological option in surgical therapy of early breast cancer. Permacol® is an acellular dermal matrix (ADM) placed between the implant and the skin to improve lower pole projection and implant coverage. The aim of our study was to evaluate the outcome with a focus on patient satisfaction after 6 months and to analyze physical changes of ADM. METHODS 10 patients who underwent SSM with Permacol® were analyzed retrospectively. All patients were followed using a satisfaction questionnaire and an ultrasound evaluation of the tissue thickness of the pectoralis muscle and the Permacol®. RESULTS No intraoperative complications were observed. One patient required removal of the implant for necrosis after 3 months. Half of the patients underwent secondary corrective surgery. A statistically significant thinning of the pectoralis muscle was observed, compared to the thickening of the Permacol®. A majority of the patients were satisfied with the operation, and we found a correlation between lower body mass index and patient satisfaction. CONCLUSION In our small case series Permacol®-assisted immediate reconstruction is shown to be an option for selected cases. Physical changes of Permacol® result in a symmetrical coverage of the implant, which may improve cosmetic outcome.

Abstract
The suppression of elements associated with wound contracture and unfavorable scarring is a potentially important strategy in clinical wound management. In this study, the presence of α smooth muscle actin (αSMA), a protein involved in wound contraction, was analyzed in a series of wounds in which bovine fetal collagen (BFC) acellular dermal matrix (PriMatrix) was used in staged split thickness skin graft procedures. The results obtained through histological and quantitative image analyses of incidental biopsies from these wounds demonstrated a suppression of αSMA in the wound regions occupied by assimilated BFC relative to increased levels of αSMA found in other areas of the wound. The αSMA levels found in assimilated BFC were similar to αSMA levels in uninjured human dermis. These findings suggest a mechanism by which application of BFC could decrease contraction of full thickness skin wounds.

This study compares the subcutaneous expander placement to the traditional submuscular placement and describes our early experience with the expander insertion plane-choosing algorithm. METHODS A retrospective study of patients who underwent two-stage immediate breast reconstruction from May 2012 to October 2014 was conducted. All expander insertion planes were chosen using the same algorithm. Expansion, pain, and complications were compared between two groups. RESULTS The study included 88 patients (158 expanders; 50 subcutaneous and 108 submuscular). The subcutaneous group had a higher intraoperative expansion ratio (p < 0.001), high first postoperative expansion ratio (p < 0.001), shorter duration of expansion (p = 0.02), less number of expansion visits (p = 0.002), and less average pain during admission (p = 0.004). Significant differences in the intraoperative and first postoperative expansion ratios in patients with postmastectomy radiation therapy were also found between the two groups (p = 0.005 and 0.01, respectively). Complications during expansion and after second-stage autologous flap reconstruction were comparable between two groups. CONCLUSION The subcutaneous expander placement was associated with greater intraoperative and first postoperative expansion, shorter expansion duration, less expansion visits, and less pain. With the expander insertion plane-choosing algorithm, subcutaneous expander placement could be performed with comparable complications rates with the submuscular placement during expansion and after second-stage autologous flap reconstruction. Further studies can be performed due to the lack of long-term complications following second-stage implant reconstruction in the subcutaneous approach.

A Prospective Study Assessing Complication Rates and Patient-Reported Outcomes in Breast Reconstructions Using a Novel, Deep Dermal Human Acellular Dermal Matrix. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2016; 3:e585. [PMID: 26894010 PMCID: PMC4727694 DOI: 10.1097/gox.0000000000000574] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2015] [Accepted: 11/09/2015] [Indexed: 11/25/2022]
Abstract
UNLABELLED The value proposition of an acellular dermal matrix (ADM) taken from the deep dermis is that the allograft may be more porous, allowing for enhanced integration and revascularization. In turn, this characteristic may attenuate complications related to foreign body reactions, seromas, and infection. However, this is juxtaposed against the potential loss of allograft structural integrity, with subsequent risk of malposition and extrusion. Despite the active use of novel, deep dermal ADMs, the clinical outcomes of this new technology has not been well studied. METHODS This is a prospective study to evaluate surgical and patient-reported outcomes using a deep dermal ADM, FlexHD Pliable. Surgical outcomes and BREAST-Q patient-reported outcomes were evaluated postoperatively at 2- and 6-month time points. RESULTS Seventy-two breasts (41 patients) underwent reconstruction. Complication rate was 12.5%, including 2 hematomas and 7 flap necroses. One case of flap necrosis led to reconstructive failure. Notably, there were no cases of infection, seroma, or implant extrusion or malposition. Average BREAST-Q scores were satisfaction with outcome (70.13 ± 23.87), satisfaction with breasts (58.53 ± 20.00), psychosocial well being (67.97 ± 20.93), sexual well being (54.11 ± 27.72), and physical well being (70.45 ± 15.44). Two-month postoperative BREAST-Q scores decreased compared with baseline and returned to baseline by 6 months. Postoperative radiation therapy had a negative effect on satisfaction with breasts (P = 0.004) and sexual well being (P = 0.006). CONCLUSIONS Deep dermal ADM is a novel modification of traditional allograft technology. Use of the deep dermal ADM yielded acceptably low complication rates and satisfactory patient-reported outcomes.

Abstract
BACKGROUND Although the use of acellular dermal matrix (ADM) has increased exponentially, debates regarding its safety are still ongoing. There have been several meta-analyses; however, potential learning curve effects of using ADM might affect their outcomes. The present meta-analysis reappraised the potential benefits and risks of ADM on the outcome of implant-based breast reconstruction using recent publications. METHODS Electronic databases were searched to identify relevant studies comparing the outcome of ADM use with traditional submuscular technique, which were published from 2011 to 2014. The relative risks of postoperative complications and mean difference of expander dynamics between the two groups were computed. RESULTS A total of 23 studies representing 6199 cases were analyzed. There was one randomized controlled study and three prospective cohort studies. The use of ADM significantly elevated the risks of infection, seroma, and mastectomy flap necrosis, but did not affect the risks of implant loss, unplanned reoperation, and total complications. The risks of capsular contracture and implant malposition were significantly reduced by the application of ADM. The ADM allows for significantly greater intraoperative expansion and reduced frequency of injection to complete expansion. CONCLUSIONS According to this meta-analysis, the increasing risks for serious complication and overall morbidity related to ADM use might not be remarkable, while its benefits for preventing late complications and improving expander dynamics might be appreciable. Although future well-controlled studies would be required, the implant-based breast reconstruction using ADM may be reliable and advantageous.

Abstract
BACKGROUND Acellular dermal matrix for implant-based breast reconstruction appears to cause higher early complication rates, but long-term outcomes are perceived to be superior. This dichotomy is the subject of considerable debate. The authors hypothesized that patient characteristics and operative variables would have a greater impact on complications than the type of acellular dermal matrix used. METHODS A retrospective cohort study was performed of consecutive patients who underwent two-stage, implant-based breast reconstruction with human cadaveric or bovine acellular dermal matrix from 2006 to 2012 at a single institution. Patient characteristics and operative variables were analyzed using logistic regression analyses to identify risk factors for complications. RESULTS The authors included 564 reconstructions in the study. Radiation therapy and obesity increased the odds of all complications. Every 100-ml increase in preoperative breast volume increased the odds of any complication by 1 percent, the odds of infection by 27 percent, and the risk of explantation by 16 percent. The odds of seroma increased linearly with increasing surface area of acellular dermal matrix. Odds of infection were higher with an intraoperative expander fill volume greater than 50 percent of the total volume. Risk of explantation was twice as high when intraoperative expander fill volume was greater than 300 ml. CONCLUSIONS Radiation therapy, obesity, larger breasts, higher intraoperative fill volumes, and larger acellular dermal matrices are all independent risk factors for early complications. Maximizing the initial mastectomy skin envelope fill must be balanced with the understanding that higher complication rates may result from a larger intraoperative breast mound.

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.

Treatment of irradiated expanders: protective lipofilling allows immediate prosthetic breast reconstruction in the setting of postoperative radiotherapy. Aesthetic Plast Surg 2013; 37:1146-52.

Abstract
BACKGROUND Immediate two-stage prosthetic breast reconstruction in the setting of postmastectomy radiotherapy (PMRT) currently is hardly achieved with the fast-track expander exchange proposed by Cordeiro and colleagues or the delayed-immediate breast reconstruction proposed by Kronowitz and Robb. Each of these techniques has important drawbacks and complications. To overcome these problems, the authors in 2011 described lipofilling on irradiated expanders in patients undergoing unplanned PMRT (Cagliari University Hospital [CUH] protocol) for early breast cancers with specific risk factors. The authors report their experience after expanding the use of such a protocol for any immediate expander/implant reconstruction in a patient undergoing PMRT. METHODS The timing for advanced breast cancer involves immediate reconstruction with a tissue expander, complete tissue expansion, radiotherapy (RT) after neoadjuvant chemotherapy starting 2-3 months after mastectomy, one or two fresh fat-grafting sessions at least 6 weeks after RT, and an expander-implant exchange with anterior capsulectomy at least 3 months after the completion of fat grafting. The timing for early breast cancers with specific risk factors involves immediate reconstruction with a tissue expander, complete tissue expansion during postoperative chemotherapy, RT 6 months after mastectomy, one or two fat-grafting sessions 6 weeks after RT, and an expander-implant exchange with anterior capsulectomy at least 3 months after the completion of fat grafting. From 2008 to 2012, 16 patients undergoing total mastectomy and immediate expander-implant breast reconstruction with subsequent PMRT were treated according to the CUH protocol. RESULTS The results have been extremely encouraging, with rates of ulceration and implant exposure in the radiotreated area dropping to 0 %. These results were retrospectively compared with those for a control group of 16 patients who underwent immediate implantation of an expander. In this latter group, the extrusion rate of the implant in the end was 31.25 %, and this was statistically significant (p < 0.03). The shape and symmetry also were significantly better in the lipofilled patients. CONCLUSION Protective lipofilling on irradiated expanders appears to be a valid technique for avoiding ulceration and implant exposure after PMRT while allowing a complete expansion.
