Breast Implants

BackgroundBreast implants are commonly placed postbreast cancer reconstruction, cosmetic augmentation, and gender-affirming surgery. Breast implant illness (BII) is a systemic complication associated with breast implants. Patients with BII may experience autoimmune symptoms including fatigue, difficulty concentrating, hair loss, weight change, and depression. BII is poorly understood, and the etiology is unknown. The purpose of this literature review is to characterize BII autoimmune disorders and determine possible causes for its etiology.MethodsThe PubMed, Google Scholar, Embase, Web of Science, and OVID databases were interrogated from 2010 to 2020 using a query strategy including search term combinations of "implants," "breast implant illness," "autoimmune," and "systemic illness."ResultsBII includes a spectrum of autoimmune symptoms such as fatigue, myalgias/arthralgias, dry eyes/mouth, and rash. A review of epidemiological studies in the past ten years exhibited evidence affirming an association between breast implants and autoimmune diseases. The most commonly recognized were Sjogren's syndrome, rheumatoid arthritis, systemic sclerosis, chronic fatigue syndrome, and Raynaud's syndrome. Explantation resulted in alleviation of symptoms in over 50% of patients, strengthening the hypothesis linking breast implants to BII. Studies have shown that silicone is a biologically inert material and unlikely to be the cause of these symptoms. This is supported by the fact that increased risk of autoimmune disease was also reported in patients with other implantable biomaterials such as orthopedic implants. Recent studies shed light on a possible role of bacterial biofilm and subsequent host-pathogen interactions as a confounding factor to this problem.ConclusionBII could be dependent on biofilm infection and the microenvironment around the implants. The true pathophysiology behind these complaints must be further investigated so that alternative treatment regimens other than explantation can be developed. Translational significance of these studies is not limited to breast implants but extends to other implants as well.

Although capsular contracture remains one of the major problems following silicone breast implantation, the associated mechanism has yet to be determined. This study thus aimed to investigate capsule formation and capsular contracture using three types of implants with different surface topographies in vivo. Three types of implants (i.e., smooth, macrotexture, and nanotexture) with different surface topographies were inserted in a total of 48 Wistar rats. After 4 and 12 weeks, the samples were analyzed via histological, immunohistochemical, and Western blot examination. To identify implant movement, the degree to which implant position changed was measured. And the surface topography was characterized using scanning electron microscopy. Hematoxylin-eosin staining showed that the nanotexture type implant promoted significant decreases in capsule thickness at 12 weeks (P < 0.05), while Masson trichrome staining showed decreased collagen fiber density with the same implant type. Immunohistochemical and Western blot examination revealed reduced fibrosis markers (myofibroblast, and transforming growth factor beta-1) in the nanotexture surface implant. Meanwhile, implant location evaluation found that the nanotexture and smooth surface implants had significantly increased movement (P < 0.05). The nanotexture surface implant had been found to reduce capsule formation given that it minimizes the effects of factors related to foreign body reaction.

BackgroundBreast implants (BI) are widely used in plastic surgery, though they are not lifetime devices. Average life before rupture is reported to be around 10-15 years. No consensus exists regarding which factors are involved.ObjectivesFollowing FDA recommendations, this study aims at identifying potential risk factors by evaluating their effect on BI rupture cases.MethodsIn this observational study, 763 BI patients were operated between 2003 and 2019, with a mean implant indwelling of 12.2 years. Patients that returned for follow-up were administered a questionnaire regarding postoperative lifestyle and habits. Implant rupture rate was 15.1%, while BI lifespan was 10.1 years. We obtained complete data from 191 breast implant patients (288 implants). Twenty-three potential risk factors were evaluated and divided in four categories: patient-related, surgery-related, postoperative complications/symptoms, and postoperative care/lifestyle habits. Odds Ratio (OR) for each factor was calculated. Linear regression analysis was calculated for those with a significant OR.ResultsWe report 120 patients (195 implants) with intact and 71 (93 implants) with ruptured devices. BIs were macrotextured in 95.1% of cases (86.8% Allergan BIOCELL). OR was significant for underwire bra use (OR: 2.708), car seat belts (OR: 3.066), mammographic imaging (OR: 2.196), weightlifting (OR: 0.407) and carry-on heavy purses and backpacks (OR: 0.347).ConclusionWearing underwire bras, seat belts and undergoing mammography increases the risk of rupture. Weightlifting and carry heavy bags do not increase that risk. Implant rupture is directly linked with time of indwelling. Postoperative recommendations in BI patients should consider findings from our study, though larger multicenter studies should be encouraged.Level of evidence ivThis journal requires that authors assign a level of evidence to each article.

The aim of bilateral breast augmentation (BBA) is not just to enlarge the breast, but to create an aesthetically pleasing enlarged breast. This is an elective surgical procedure, often performed on young healthy women-yet the incidence of revision is in the region of 20%. There is a wide variation in what these patients want cosmetically. A "10 point" plan is presented which should be considered in every patient undergoing BBA. Each point addresses a critical issue in BBA. Understanding the mechanics of the procedure is as important as knowing the technical details of the operation. There is no simple "one operation for all" approach in breast augmentation, but the hybrid augmentation represents an advance in this procedure. The incidence of revision surgery should be lowered when a careful, "thought out" approach is adopted.Level of Evidence V This journal requires that authors assign a level of evidence to each article.
