Abstract: Requests for removal of silicone breast implants are increasingly common. Often patients request a capsulectomy in either a total or “en bloc” form. Capsulectomy adds time, cost, and morbidity to removal of implant procedures. This article examines the reasoning given by practitioners for undertaking the procedure, and reviews the literature to examine the validity of those arguments. Except where pathology of the capsule is demonstrable (Breast implant related anaplastic large cell lymphoma, BIR-ALCL), there is currently no indication for prophylactic removal of capsules following removal of breast implants. Given the potential risks, and lack of evidence for the procedure, both patient and surgeons should be aware of the potential consequences.

Abstract: Breast augmentation procedures using silicone implants have become increasingly popular over the past six decades. This article addresses the concerns of patients regarding implant strength by providing clinicians with valuable information in addition to video and pictorial evidence to share, fostering reassurance. The article focuses on the structural integrity and stability of breast implants, which play a critical role in their long-term performance and patient satisfaction. Specifically, it examines the industry standards outlined by the International Organization for Standardization (ISO), with a particular emphasis on ISO14607-2018, which encompasses a range of mechanical and physio-mechanical tests, including the assessment of silicone gel-fill firmness, evaluation of shell integrity, and examination of the impact of environmental conditions on implant performance. Breast implants are not static devices and are subject to aging and fatigue-based degradation. This emphasizes the need for ongoing monitoring and evaluation to ensure the long-term safety and satisfaction of patients. By providing a comprehensive examination of breast implant structure and industry standards, this article equips clinicians with the necessary knowledge to address patient concerns and foster confidence in the safety and longevity of breast augmentation procedures using silicone implants.

Abstract: There are numerous measuring systems that practitioners employ as part of their presurgical assessment for breast implant surgery. These range from direct measurements of patients using a tape measure, to assessment of standardized photographs and 3-dimensional scanning technologies. This personal view describes the authors system, developed over 20 years. The data yielded have assisted in assessing breast symmetry, ptosis, and match of implant to patient, with proven benefits for managing patient outcomes and expectations. It is simple, rapid to undertake, and requires inexpensive measuring equipment to provide useful data.

Abstract: Currently there are limited implant-based options for cosmetic breast augmentation, and problems associated with those have been increasingly appreciated, most commonly capsular contracture, which occurs due to a chronic foreign body reaction against non-degradable implant materials such as silicone and polyurethane leading to scar tissue formation, pain, and deformity. The underlying biomechanical concepts with implants create a reciprocal stress-strain relationship with local tissue, whilst acting as a deforming force. This means that with time, as the implant continues to have an effect on surrounding tissue the implant and host's biomechanical properties diverge, making malposition, asymmetry, and other complications more likely. Research directed towards development of alternative therapies based on tissue engineering and regenerative medicine seeks to optimize new tissue formation through modulation of tissue progenitors and facilitating tissue regeneration. Scaffolds can guide the process of new tissue formation by providing both an implant surface and a three-dimensional space that promotes the development of a microenvironment that guides attachment, migration, proliferation, and differentiation of connective tissue progenitors. Important to scaffold design are the architecture, surface chemistry, mechanical properties, and biomaterial used. Scaffolds provide a void in which vascularization, new tissue formation, and remodelling can sequentially occur. They provide a conduit for delivery of the different cell types required for tissue regeneration into a graft site, facilitating their retention and distribution. Whilst recent research from a small number of groups is promising, there are still ongoing challenges to achieving clinical translation. This article summarizes the biomechanical principles of breast implants, how these impact outcomes, and progress in scaffold-guided tissue engineering approaches to cosmetic breast augmentation.

Abstract: Seroma is a common problem following abdominoplasty surgery. Both compressive garments with drains and progressive tension sutures have their advocates to minimise seroma formation. This is a retrospective study in which patients underwent an identical surgical procedure, except for use of drains and garments in comparison to progressive tension sutures between 2005 and 2020. Two hundred thirty-two patients were included in the study 61 in the drains and garment group (DG group), and 171 with progressive tension sutures (PTS group) alone. There was a lower incidence of seroma formation in the PTS group (X² (1, N = 232) = 6.35, P = .012). The weight of tissue excised in the PTS group was greater than the DG group (P < .001). There was there a significantly higher tissue excision weights for patients who developed a seroma, compared with those who did not (P=.02). Patients, who developed a seroma in the PTS group, had significantly greater excision weights than the DG group. Liposuction did not change the incidence of seroma in each group (X² (4, N = 232) = 6.701, P = .08 n/s). This study demonstrates the effectiveness of progressive tension sutures in reducing the incidence of seroma formation following abdominoplasty, particularly when large excision weights are involved. The addition of small volume liposuction distant to the abdominal flap does not increase the incidence of seroma formation.Level of Evidence III This journal requires that authors assign a level of evidence to each article.
