Guillermo Vázquez
This paper presents patients satisfaction using anatomical polyurethane breast implants. We performed surgery on 525 patients, 370 of which were primary and 155 were secondary to various causes such as capsular contracture, ruptured implants, volume changes, and incorrect positioning of the implant. The advantages of silicone polyurethane covers shown high level of patient satisfaction, low incidence of capsular contracture, and absence of implant rotation, and late seroma.

Silicone breast implants have been in use for nearly 6 decades. In this time they have undergone significant changes in design and use. They have been subject to intense scrutiny with regard to safety and efficacy, including an almost 10 years moratorium on their use. The current generations of implants have been followed via the manufacturer's Core studies in order to obtain long term data regarding safety and complications. The results of the more recent studies are compiled in this review. Rupture rates are initially very low and begin to increase after 6-8 years of implantation...

BACKGROUND: Breast capsular contracture remains an elusive problem faced by plastic surgeons and is the leading long-term complication after breast implantation. Follistatin (Fst) is a protein with known anti-inflammatory and antifibrotic properties and has the potential to limit the severity of diseases associated with inflammation and fibrosis such as capsular contracture. The aim of this study was to examine the effect of Fst288 on capsular fibrosis around silicone implants in a mouse model...

BACKGROUND: Capsular contracture is an incurable complication after silicone-based implant surgery. Myofibroblast is the predominant cell in the contracted capsule. We hypothesized that human adipose derive stromal cells (hASCs) together with fibroblast may show a similar phenotypic characteristics of myofibroblast after the treatment of inflammatory cytokines in vitro. MATERIALS AND METHODS: Interleukin 3 (IL-3) and granulocyte macrophage colony stimulating factor (GM-CSF) were treated in the culture of hASCs and HDFs...

Primary breast lymphoma is a rare disease and accounts for 0.5% of cases of breast cancer. Most primary breast lymphomas develop from B cells, and the involvement of T cells is rare. Anaplastic large cell lymphoma (ALCL) is a recently discovered T-cell lymphoma associated with breast implants. Only a few cases have been reported to date. It is believed that the incidence of ALCL is increasing because of the increasing number of breast implants. The clinical presentation is variable and can manifest as a palpable mass in the breast or armpit, breast pain, or capsular contracture...

BACKGROUND: Silicone implants are frequently used in augmentation rhinoplasty in Asians. A common complication of silicone augmentation rhinoplasty is capsular contracture. This is similar to the capsular contracture after augmentation mammoplasty, but a classification for secondary contracture after augmentation rhinoplasty with silicone implants has not yet been established, and treatment algorithms by grade or severity have yet to be developed. METHODS: Photographs of 695 patients who underwent augmentation rhinoplasty with a silicone implant from May 2001 to May 2015 were analyzed...

We hypothesize that periodically early, local suppression of cysteinyl leukotrienes (CysLTs), which are potent inflammatory mediators, can reduce the fibrotic capsular contracture around silicone implants. We tested this hypothesis with the silicone implants enabled with the sustained release of montelukast, a CysLT receptor antagonist, for 3 and 15days. In this work, we inserted each of the distinct implants into the pocket of the subpanniculus carnosus plane of living rats and performed histological and immunofluorescent (IF) analyses of the tissues biopsied at predetermined periods for 12weeks after implant insertion...

PURPOSE: To assess the capsules formed by silicone implants coated with polyurethane foam and with a textured surface. METHODS: Sixty-four Wistar albinus rats were divided into two groups of 32 each using polyurethane foam and textured surface. The capsules around the implants were analyzed for 30, 50, 70 and 90 days. Were analyzed the following parameters: foreign body reaction, granulation tissue, presence of myofibroblasts, neoangiogenesis, presence of synovial metaplasia, capsular thickness, total area and collagen percentage of type I and III, in capsules formed around silicone implants in both groups...

BACKGROUND: Capsular contracture remains the most frequent long-term complication after augmentation mammoplasty with silicone implants. Thereby, the main part of the fibrotic capsule is collagen. The collagenase of the bacterium Clostridium histolyticum is approved for the treatment of fibrotic diseases and has been demonstrated to be effective for capsular fibrosis treatment in the short term. However, long-term effectiveness is currently unknown but mandatory for clinical utilization...

Background: Extra full projection implants are used in a select group of aesthetic breast surgery patients. Their use is selective enough that they have not been included in long term manufacturer studies and the indications for their use have attracted much debate. Only a handful of studies have reported the outcomes from implantation of these devices. Objectives: We review our experience of using extra full projection anatomically shaped macrotextured silicone gel implants discussing our rationale, indications, and results...

Eric Swanson
BACKGROUND: The prevailing theory for capsular contracture after breast augmentation is a subclinical capsular infection. A capsulectomy, site change, and implant replacement are recommended. An open capsulotomy leaves the capsule in the patient. Theoretically, such a procedure would be ineffective because it does not remove the infected tissue. Recurrences occurred frequently in women treated in the 1970s when leaky silicone gel implants were in use. Open capsulotomy has not been studied in women implanted with third-generation devices...

PURPOSE: Silicone rubber implants have been widely used to repair soft tissue defects and deformities. However, poor biocompatibility can elicit capsule formation, usually resulting in prosthesis contracture and displacement in long-term usage. To overcome this problem, this study investigated the properties of silicone rubber materials with or without a microgroove-patterned surface and with or without carbon (C)-ion implantation. MATERIALS AND METHODS: Atomic force microscopy, X-ray photoelectron spectroscopy, and a water contact angle test were used to characterize surface morphology and physicochemical properties...

BACKGROUND: Silicon implants constitute a major part of plastic surgery practice. Although materials with high biocompatibility have been used around the implants, capsule formation still develops and progressive nature of this process results in capsule contraction. The aim of this study is to evaluate the effects of hyaluronic acid injected around the silicon block on the capsule structure. METHODS: Twenty Wistar albino rats were used in the study. Rats were divided into two main groups (group 1 and group 2) and two subgroups...

The periareolar approach is limited by areolar diameter. Asian women typically have smaller areolae than Western women. Voluminous and form-stable silicone implants demand larger incisions. Zigzag transareolar approaches closely approximate the nipple and improve exposure, but scar appearance remains problematic, and there is a risk of ductal injury and capsular contracture. We prefer a zigzag incision that straddles the areolar border. Between 2013 and 2015, 11 augmentation mammoplasties (20 incisions) were performed through a transareolar-periareolar (TAPA) incision...

BACKGROUND: Alloplastic materials are a mainstay in Asian rhinoplasty. However, the outline of alloplastic implants can become conspicuous over time in rhinoplasty patients, which is a significant cause for revision. In revision rhinoplasty, alloplastic materials can remain a viable and affordable option in Asian patients. The acellular dermal matrices (ADM) are often used to interface between the silicone material and the skin envelope. This study assesses histologic changes following implantation of ADM-covered silicone material in rats...

BACKGROUND: First-generation polyurethane foam-coated breast implants were associated with a low risk of capsular contracture (CC), but the risk of CC with modern polyurethane-coated silicone implants has not been established. OBJECTIVES: The authors sought to determine the long-term rates of CC after primary breast augmentation with Microthane, a polyurethane-coated silicone gel implant. METHODS: A total of 131 patients (255 breasts) were evaluated in a retrospective study...

Breast augmentation with silicone implants is one of the most common procedures performed by plastic surgeons around the world. Capsular contracture is a frequent complication in breast augmentation and reconstructive surgery, that requires invasive intervention. The inflammatory response to implanted mammary prostheses appears to be directly associated to capsular contracture. This review discusses the evidences from rat models studies, on the role of inflammation and fibrosis in capsular contraction and its relation to silicone breast implants surface...

BACKGROUND: Natrelle 410 silicone breast implants are approved in the United States for breast augmentation, reconstruction, and revision. METHODS: In two ongoing, prospective, multicenter 10-year studies, 17,656 subjects received Natrelle 410 implants for augmentation (n = 5059), revision-augmentation (n = 2632), reconstruction (n = 7502), or revision-reconstruction (n = 2463). Capsular contracture, implant malposition, and late seroma were documented. Cox proportional hazards regression analyses evaluated potential associations between subject-, implant-, and surgery-related factors and these complications...
