BACKGROUND: Complications associated with breast implants pose a significant obstacle to improving the quality of life for patients undergoing implant-based breast reconstruction. Due to the intricate nature of their presentation, diagnosis often becomes challenging and perplexing. Herein, we present a case report detailing the diagnostic and therapeutic processes employed in managing implant-related complications in a patient with multiple malignancies who underwent immediate breast reconstruction following mastectomy.
UNASSIGNED: The patient, a 48-year-old woman, presented with severe pain and hardening in her left breast. She had previously undergone nipple-sparing mastectomy followed by immediate implant-based breast reconstruction 3 years ago.
METHODS: Upon admission, we suspected a simple diagnosis of capsular contracture. However, upon investigation, she had a medical history of colon cancer, breast cancer, and acute B-lymphoblastic leukemia. Furthermore, she recently experienced nipple hemorrhage.
METHODS: Considering her clinical manifestations, we postulated the possibility of tumor recurrence along with potential presence of breast implant-associated anaplastic large cell lymphoma. The situation took a new turn, as diagnostic imaging techniques including breast MRI, and ultrasound revealed indications of potential prosthesis rupture and periprosthetic infection.
RESULTS: Ultimately, en bloc capsulectomy with implant removal was performed, revealing no evidence of implant rupture or infection but rather indicating delayed hematoma formation.
CONCLUSIONS: An accurate diagnosis of complications associated with breast prosthesis reconstruction is crucial for effective treatment. The examination and treatment processes employed in this case offer valuable insights toward achieving a more precise diagnosis of prosthesis-related complications, particularly in patients with complex medical histories.

Breast augmentation is the most commonly performed aesthetic surgery procedure in women worldwide. The use of the subfascial plane has been suggested to decrease the incidence of capsular contracture compared with the subglandular plane, while simultaneously avoiding the complication of animation deformity in the subpectoral plane. The aim of this systematic review and meta-analysis was to compare the adverse outcomes of subfascial vs subglandular planes in breast augmentation. This review was registered a priori on OSF (https://osf.io/pm92e/). A search from inception to June 2023 was performed on MEDLINE, Embase, and CENTRAL. A hand search was also performed. All randomized and comparative cohort studies that assessed the use of the subfascial plane for breast augmentation were included. Outcomes evaluated included the incidences of seroma, hematoma, infection, rippling, capsular contracture, and revision surgery. Ten studies were included in this systematic review. Three randomized controlled trials and 7 comparative cohort studies were used for quantitative synthesis. There was a significant difference favoring subfascial compared with subglandular planes in the incidence of hematoma, rippling, and capsular contracture. All included studies had a high risk of bias. The current evidence suggests that the subfascial plane for breast augmentation decreases the risk of capsular contracture, hematoma, and rippling compared with the subglandular plane. Further randomized evidence with high methodological rigor is still required to validate these findings.
METHODS:

BACKGROUND: Esthetic complications, such as capsular contracture and soft-tissue contour defects, hinder the desired outcomes of breast reconstruction. As subclinical infection is a prevailing theory behind capsular contracture, we investigated the effects of post-operative infections on these issues and revision procedures.
METHODS: We conducted a retrospective database study (2007-2021) on breast reconstruction patients from the MarketScan® Databases. Esthetic complications were defined by their associated revision procedures and queried via CPT codes. Severe capsular contracture (Grade 3-4) was defined as requiring capsulotomy or capsulectomy with implant removal or replacement. Moderate and severe soft-tissue defects were determined by the need for fat grafting or breast revision, respectively. Generalized linear models were used, adjusting for comorbidities and surgical factors (p < 0.05).
RESULTS: We analyzed the data on 62,510 eligible patients. Post-operative infections increased the odds of capsulotomy (OR 1.59, p < 0.001) and capsulectomy (OR 2.30, p < 0.001). They also raised the odds of breast revision for severe soft-tissue defects (OR 1.21, p < 0.001). There was no significant association between infections and fat grafting for moderate defects. Patients who had post-operative infections were also more likely to experience another infection after fat grafting (OR 3.39, p = 0.0018). In two-stage reconstruction, infection after tissue expander placement was associated with greater odds of infection after implant placement.
CONCLUSIONS: Post-operative infections increase the likelihood of developing severe soft-tissue defects and capsular contracture requiring surgical revision. Our data reinforce the role of infections in the pathophysiology of capsular contracture. Additionally, infections elevate the risk of subsequent infections after fat grafting for moderate defects, further increasing patient morbidity.

BACKGROUND: Nanotextured breast implants (classified as smooth implants by the latest ISO 14607:2018) have been described as possibly reducing major textured implant-related complications such as capsular contracture and breast implant-associated anaplastic large cell lymphoma. On the other hand, microtextured breast implants benefit from an optimal safety profile based on a much larger body of literature.
OBJECTIVE: The aim of this study was to directly compare the incidence of complications between Motiva Ergonomix (Establishment Labs Holdings, Inc., Alajuela, Costa Rica) and POLYTECH MESMO (POLYTECH Health & Aesthetics GmbH, Dieburg, Germany) breast implants, especially regarding the displacement issues that might arise after breast augmentation.
METHODS: Consecutive patients who previously underwent surgery by the same physician for placement of Motiva Ergonomix and POLYTECH MESMO implants were included in this study. They were divided into 2 groups according to the type of implant. The onset of complications was assessed through survival analysis.
RESULTS: Data were collected from 329 patients, 185 (56.2%) with POLYTECH MESMO and 144 (43.8%) with Motiva Ergonomix implants. The median follow-up was 8 months for both groups. Of the 42 women (12.8%) who experienced at least one complication, 26 belonged to the Motiva Ergonomix subgroup (P = .013). The most represented complications during this period resulted from displacement issues, with a clear prevalence of bottoming out in the Motiva Ergonomix cohort: 15 cases vs 0 cases in the POLYTECH MESMO cohort (P < .001). For 7 patients, a reoperation was required, more frequently for patients with Motiva Ergonomix implants (4.2% vs 0.5%; P = .046).
CONCLUSIONS: POLYTECH MESMO devices provided a more favorable outcome. Motiva Ergonomix devices revealed a concerning incidence of displacement issues during the first postsurgery years, with no advantage over other major complications.
METHODS:

BACKGROUND: Polyurethane (PU)-coated breast implants are known for their strong integration into breast tissue and the formation of capsules around them. However, capsular contracture can pose both aesthetic and clinical challenges.
OBJECTIVE: The objectives of this study were to analyze the biological and morphological characteristics of the capsular tissue surrounding PU-coated implants, irrespective of their contracture status, and to assess their potential suitability as a flap in revisional breast surgery for capsular contracture.
METHODS: A total of 23 tissue samples were harvested from the capsules surrounding PU-coated breast implants in 12 female patients during replacement or revisional surgery. We evaluated collagen abundance, cellular and vascular density, inflammation, collagen band types and alignment, synovial metaplasia, capsule thickness, and the expression of inflammatory biomarkers and myofibroblasts with immunohistochemical techniques. Scanning electron microscopy was employed to assess implant surface characteristics over time.
RESULTS: We found a significant association of capsule contraction with longer implantation durations and greater implant surface roughness (P = .018 and P = .033, respectively). Synovial metaplasia was significantly more frequent in noncontracted capsules (P = .0049). Both capsule types consisted of paucicellular, type I collagen-rich compact fibrous tissue with low vascularization. There was a marked reduction in inflammatory cells within the foreign body granuloma. The expression of inflammatory biomarkers in the capsular tissue was negligible.
CONCLUSIONS: Given the reduced levels of inflammatory and vascular components within the dense, fibrous capsular tissue, we consider them to be viable alternatives for capsular flaps in revisional surgery. This strategy has the potential to mimic the reconstruction achieved with acellular dermal matrix.

UNASSIGNED: Breast cancer with about 2.3 million diagnoses and 685,000 deaths globally is the most frequent malignancy in the female population. Continuous research has led to oncological and reconstructive advances in the management of breast cancer, thus improving outcomes and decreasing patient morbidity. Nowadays, the submuscular expander and prosthesis (E/P) implant-based breast reconstruction (IBR) accounts for 73% of all reconstructions. Despite its widely accepted efficacy, the technique is not free from complications and up to 28% of cases require revision surgery for mechanical complications such as capsular contracture, implant displacement/rotation, and implant rupture. With this study, the authors report their experience in the management of E/P IBR revision surgery through the technique of Selective Capsulotomies (SCs) and Partial Capsulectomy (PC).
UNASSIGNED: A retrospective study was conducted on patients who had previously undergone E/P IBR and presented for revision reconstruction between January 2013 and May 2023 at the Department of Plastic Surgery of the University of Siena, Italy. Reasons for revision included capsular contracture, implant displacement/rotation, and implant rupture. Revision reconstructions involved SC and PC with implant replacement. Fat grafting was also considered. The complication rate was evaluated by analysis of patients\' medical records. Patients\' satisfaction with the treatment was assessed through a specific questionnaire.
UNASSIGNED: 32 patients underwent revision surgeries. No early complication occurred. Recurrence rate was assessed at 19% with average follow-up of 59 months (range: 13-114 months). The average time between revision surgery and recurrence was 3 years (range: 1-6 years). 23 patients answered the questionnaire and were overall satisfied with the treatments (8.29/10).
UNASSIGNED: SC possibly associated to PC is a valuable option for E/P IBR revision surgery with minimal complications, reduced surgical trauma, short operating time, and relatively low recurrence risk. In addition, treated patients are overall satisfied with the results over time.

BACKGROUND: Capsular contracture is traditionally evaluated with the Baker classification, but this has notable limitations regarding reproducibility and objectivity.
OBJECTIVE: The aim of this study was to develop and validate procedure-specific histopathological scoring systems to assess capsular contracture severity.
METHODS: Biopsies of breast implant capsules were used to develop histopathological scoring systems for patients following breast augmentation and breast reconstruction. Ten histological parameters were evaluated by multivariable logistic regression to identify those most associated with capsular contracture. Significant parameters (P < .05) were selected for the scoring systems and assigned weighted scores (1-10). Validation was assessed from the area under the curve (AUC) and the mean absolute error (MAE).
RESULTS: A total of 720 biopsies from 542 patients were included. Four parameters were selected for the augmentation scoring system, namely, collagen layer thickness, fiber organization, inflammatory infiltration, and calcification, providing a combined maximum score of 26. The AUC and MAE for the augmentation scoring system were 81% and 0.8%, which is considered strong. Three parameters were selected for the reconstruction scoring system, namely, fiber organization, collagen layer cellularity, and inflammatory infiltration, providing a combined maximum score of 19. The AUC and MAE of the reconstruction scoring system were 72% and 7.1%, which is considered good.
CONCLUSIONS: The new histopathological scoring systems provide an objective, reproducible, and accurate assessment of capsular contracture severity. We propose these novel scoring systems as a valuable tool for confirming capsular contracture diagnosis in the clinical setting, for research, and for implant manufacturers and insurance providers in need of a confirmed capsular contracture diagnosis.
METHODS:

BACKGROUND: Revisional surgery for aesthetic breast augmentation remains a challenging procedure. Polyurethane (PU) implants have been found to avoid capsular contracture recurrence as well as to prevent implant displacement by bio-integrating with the pocket.
OBJECTIVE: Our study aimed to assess the use of PU implants in breast revisional surgery and to provide an algorithm.
METHODS: Over a 5-year period, a prospective study was conducted involving consecutive patients undergoing implant revision. Patient demographics, previous breast procedures, and specific surgical details were documented. Postoperative outcomes were followed up.
RESULTS: Out of 92 patients (184 breasts), 78 (156 breasts) were included in the analysis. The average age was 47.5, with a BMI of 22.3 and a mean follow-up of 5 years. A majority (63%) represented secondary revisional cases, while 37% were tertiary cases. Implant size averaged 296 cc, with 53% placed in retropectoral position and 47% prepectoral. Significantly more implants in secondary cases were changed from prepectoral to retropectoral (P = .005), and in tertiary changed from retropectoral to prepectoral (P = .002). Complete capsulectomy was performed in 61.5% and partial in 25.6%. Additional lipofilling was performed in 32%, and concurrent mastopexy in 40%. Revisional surgery in our series had a 1.9% acute complication rate, 4.5% longer-term reoperation rate for corrections, 0.6% implant exchange rate, and no recurrent capsular contracture.
CONCLUSIONS: This is the first study to provide data on outcomes of revisional breast augmentation surgery with PU implants. It shows that polyurethane implants offer consistent stability and have low rates of recurrent capsular contracture in revisional surgery.
METHODS:

Antibiotics Prophylaxis to prevent capsular contracture in prosthesis-based breast surgery is common in clinical practice. However, there is currently a dearth of high-quality evidence concerning the effectiveness of antibiotic usage in this field. To identify all pertinent studies prior to January 2023, a comprehensive literature search was conducted in the PubMed, Embase, Web of Science, Cochrane Library, and Medline databases. The extracted data was then subjected to meta-analysis. Fourteen studies were retained in the analysis. According to the results, perioperative antibiotic prophylaxis did not reduce the risk of capsular contracture (RR 1.15, 95% CI 0.82-1.59, p = 0.55) or surgical-site infection (RD 0.01, 95% CI - 0.01 to 0.03, p = 0.59) compared to nonantibiotic prophylaxis. There was no statistically significant difference between extended antibiotic prophylaxis and perioperative antibiotic prophylaxis in terms of preventing capsular contracture, whether calculated by patient numbers (RD 0.01, 95% CI - 0.01 to 0.02, p = 0.87) or by total procedures (RD 0.00, 95% CI - 0.00 to 0.01, p = 0.88), or controlling surgical-site infection (RR 1.05, 95% CI 0.77-1.44, p = 0.27). Additionally, topical antibiotic irrigation did not decrease the risk of infection (RR 0.61, 95% CI 0.34-1.08, p = 0.29) and capsular contracture, regardless of patient number (RR 0.41, 95% CI 0.27-0.63, p = 0.18) or total number of procedures (RR 1.29, 95% CI 0.73-2.28, p < 0.01). Current evidence revealed that both systemic and topical antibiotic prophylaxis may not provide benefits in preventing capsular contracture in prosthesis-based breast surgery. When the occurrence of surgical-site infections is minimized to the greatest extent, the administration of additional antibiotics for reducing capsular contracture should be carefully and judiciously considered.

BACKGROUND: In breast surgeries, a lactiferous duct leading to lactic glands of breast parenchyma allows direct contamination by normal bacterial flora of the nipple-areola complex. Complete blockage of nipple flora from the intraoperative field is almost impossible.
OBJECTIVE: We aimed to analyze the microbiological profile of nipple flora of breast cancer patients who underwent an implant-based immediate breast reconstruction after a total mastectomy, and to evaluate the association of nipple bacterial flora with postoperative complications.
METHODS: A retrospective chart review was performed of patients who underwent an implant-based immediate breast reconstruction after a total mastectomy. A nipple swab culture was performed preoperatively. Patient demographics, surgical characteristics, and complications were compared between positive and negative nipple swab culture groups. Microbiological profile data including antibacterial resistance were collected.
RESULTS: Among 128 breasts, 60 cases (46.9%) had positive preoperative nipple swab culture results. Staphylococcus epidermidis accounted for 41.4% of microorganisms isolated. A multivariate logistic regression analysis of postoperative complications revealed that the presence of nipple bacterial flora was a risk factor for capsular contracture. Seven cases of postoperative infection were analyzed. In 2 cases (40% of pathogen-proven infection), the causative pathogen matched the patient\'s nipple bacterial flora, which was methicillin-resistant S. epidermidis in both cases.
CONCLUSIONS: Nipple bacterial flora was associated with an increased risk of capsular contracture. Preoperative analysis of nipple bacterial flora can be an informative source for treating clinically diagnosed postoperative infections. More studies are needed to determine the effectiveness of active antibiotic decolonization of the nipple.
