Heavy Metals in Breast Implants and Implications for Breast Implant Illness: A Systematic Review of the Literature

PURPOSE

Breast implant illness (BII) has raised concerns about breast implant safety, with some suggesting that heavy metals released from implants could contribute to systemic symptoms. This systematic review examines the presence of metal residues in breast implants and surrounding tissues, and their potential role in BII.

METHODS

A systematic literature search following PRISMA guidelines was conducted using EMBASE, Web of Science, and PUBMED for studies published until January 2024. Inclusion criteria targeted material science and clinical research on metal residues in patients with breast implants. Data on metal concentrations, detection techniques, sample types, and clinical outcomes were extracted.

RESULTS

Our search identified 304 titles, from which seven unique studies met inclusion criteria. Platinum, the most frequently detected metal, was detected in implant gel, capsular tissue, and systemic samples (blood, urine, and hair), in concentrations ranging from 0.001 to 125.27 μg/g. No consistent correlation was identified between metal levels and BII symptoms. Tin, aluminum, arsenic, and zinc were detected at low levels, below established toxicity thresholds, and often attributed to environmental exposure due to their presence in control groups. Inconsistencies in metal concentrations across studies were linked to variations in metal detection techniques and sample preparation.

CONCLUSION

We highlight the presence of metal residues, particularly platinum, in breast implants and adjacent tissue, but without a definitive link to BII. Current evidence does not support heavy metal toxicity as a primary justification for total capsulectomy in BII management. Further evidence-based clinical guidelines are needed to better inform management of BII.

Cerebellopontine angle epidermoid cyst masquerading as trigeminal neuralgia: A rare presentation and surgical outcome

Cerebellopontine (CP) angle epidermoid cysts are rare, benign, slow-growing intracranial lesions that arise from ectodermal inclusions during embryogenesis. They often present with symptoms caused by compression of adjacent structures, with trigeminal neuralgia being an uncommon presentation. A 19-year-old female presented with a 1-month history of tingling sensation on the right side of her face. MRI of the brain revealed an extra-axial cystic lesion at the right CP angle extending into the ambient cistern. The lesion appeared hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging, and dirty hyperintense on FLAIR, with diffusion restriction on DWI and no blooming on SWI. It caused a mass effect with compression of the right pons and trigeminal nerve. The patient underwent microsurgical resection of the cyst, and histopathological findings confirmed the diagnosis of an epidermoid cyst. Postoperatively, the patient showed symptomatic improvement and was advised long-term follow-up. This case emphasizes the importance of advanced imaging in diagnosing rare intracranial lesions and highlights surgical resection as an effective treatment for CP angle epidermoid cysts presenting with atypical symptoms.

Surgical Management of Breast Capsular Contracture-A Multi-institutional Data Analysis of Risk Factors for Early Complications

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.

Total Capsulectomy Without Drains is a Safe Technique Facilitated by Pectoralis Major Muscle Repair

BACKGROUND

The number of breast implant removal and capsulectomy procedures continues to increase rapidly. The aim of explant surgery should be to optimise patient outcomes from both an aesthetic and functional perspective.

OBJECTIVES

To confirm the safety of drainless total capsulectomy and to determine the role of muscle repair in explant outcomes following the removal of sub-pectoral or dual-plane cosmetic breast implants.

METHODS

We conducted a retrospective evaluation of our technique between January 2021 and November 2023. We report a single surgeon series of 140 consecutive cases of cosmetic breast implant removal from dual-plane or sub-pectoral pockets, all performed with total capsulectomy. In each case, meticulous repair of the Pectoralis major muscle was performed following capsulectomy. Drains were not used in any case. All patients were followed up for a minimum of 3 months. Patient satisfaction was assessed a minimum of 6 months post-operatively.

RESULTS

By performing the described drainless technique, there were no cases of seroma, haematoma, pneumothorax or cosmetic breast distortion in this series. 83% of patients were treated as day cases and patient satisfaction with outcomes was high.

CONCLUSIONS

Total capsulectomy without the use of drains is a novel and safe approach, aided by careful repair of the Pectoralis major muscle. There is no increased risk of seroma. The muscle repair may help to prevent post-explant cosmetic deformity of the breast.

Long-term Insights: Histopathological Assessment of Polyurethane Implant Capsules Over 24 Years

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.

OBJECTIVES

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.

Complications of Aesthetic and Reconstructive Breast Implant Capsulectomy: An Analysis of 7486 Patients Using Nationwide Outcomes Data

BACKGROUND

Despite increasing demand for breast capsular surgery to treat various benign and malignant implant-related pathologies, high-quality evidence elucidating complication profiles of capsulectomy and capsulotomy is lacking.

OBJECTIVES

The aim of this study was to provide the largest-scale analysis of associated outcomes and complications using the Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database, and to investigate clinical scenarios that may subject patients to increased risks for complications, most notably extent of capsular surgery (complete vs partial) and index indication of implantation (aesthetic vs reconstructive).

METHODS

An analysis of the TOPS database from 2008 to 2019 was performed. CPT codes were used to identify complete capsulectomy and partial capsulectomy/capsulotomy cases. Breast implant exchange procedures constituted procedural controls.

RESULTS

In total, 7486 patients (10,703 breasts) undergoing capsulectomy or capsulotomy were assessed. Relative to controls, capsulectomy (4.40% vs 5.79%), but not capsulotomy (4.40% vs 4.50%), demonstrated higher overall complication rates. Both capsulectomies (0.83% vs 0.23%) and capsulotomies (0.56% vs 0.23%) also had greater rates of seroma relative to controls. Subgroup analyses demonstrated that reconstructive patients, relative to aesthetic patients, experienced greater overall complications (6.76% vs 4.34%), and increased risks for seroma (1.06% vs 0.47%), dehiscence (0.46% vs 0.14%), surgical site infections (1.03% vs 0.23%), and implant loss (0.52% vs 0.23%). A detailed synthesis of 30-day outcomes, including all patient- and breast-specific complications, for both capsulectomy and capsulotomy, stratified according to all potential confounders, is presented herein.

CONCLUSIONS

Surgeries on the breast capsule are safe overall, although complete capsulectomies and reconstructive patients are associated with significantly increased operative risks. The present findings will enhance patient selection, counseling, and informed consent.
