RESUMO

BACKGROUND: Postoperative acute and chronic pain following breast surgery is a common complication that needs resolving to allow for improved patient outcomes. Previously, thoracic epidurals and paravertebral blocks have been the accepted standard administered intraoperatively. However, more recently the introduction of the pectoral nerve block (PECS and PECS-2 blocks) has appeared promising to control the pain more effectively, but further robust analysis is required to prove its efficacy. The authors aim to study the efficacy of a new block, S-PECS, that combines a serratus anterior and a PECS-2 block. METHODS: In this study, the authors performed a single-center, randomized, controlled, double-blind group trial in 30 female patients undergoing breast augmentation surgery with silicone breast implants and the S-PECS block. Divided into two groups of 15, the PECS group received local anesthetics and the no-PECS control group received a saline injection. All participants were followed up at recovery and at 4, 6, and 12 hours postoperatively. RESULTS: The authors' results showed that the pain score in the PECS group was significantly less than in the no-PECS group across all time points: recovery, and at 4, 6, and 12 hours. Furthermore, the patients who received the S-PEC block were 74% less likely to request pain medications compared with the no-PECS group ( P < 0.05). CONCLUSION: Overall, the modified S-PECS block is an effective, efficient, and safe method of controlling pain in patients undergoing breast augmentation surgery, with additional applications yet to be explored.

RESUMO

BACKGROUND: Breast implant safety issues have resulted in the need for global product recalls and medical device tracing. Conventional methods of breast implant tracing, have to date proven to be unsuccessful. This study aims to evaluate the effectiveness of high-resolution ultrasound (HRUS) screening in identifying implanted breast devices. METHODS: Data from 113 female patients undergoing preoperative ultrasound screening for secondary breast surgery between 2019 and 2022 was prospectively reviewed to evaluate the effectiveness of HRUS imaging with the aid of a sonographic surface catalog to identify the surface and brand type of implanted breast devices. To corroborate the findings and assess the reproducibility of the approach, further evaluations were replicated in New Zealand white rabbits and compared with the results found in humans. RESULTS: In the human recipients, implant surface and brand types were correctly identified by ultrasound imaging in 99% (112 of 113) and 96% (69 of 72) of the cases, either consultation-only or revision, respectively. This constituted an overall success rate of 98% (181 of 185). Furthermore, in a corroborating New Zealand white rabbit model where full-scale commercial implants were introduced and monitored over many months, from the total 28 analyzed, the surface was accurately identified in a total of 27 cases (the one failure being before generation of a sonograph surface catalogue), demonstrating an overall success rate of 96.4%. CONCLUSION: HRUS is, therefore, a valid and first-hand tool for breast implant imaging that can correctly evaluate both surface type and brand type alongside other variables such as implant placement, positioning, flipping, or rupture. CLINICAL RELEVANCE STATEMENT: HRUS is a valid and first-hand tool for the identification and traceability of breast implants that evaluates surface type and brand type. This low-cost, accessible, and reproducible practice provides patients with peace of mind and surgeons with a promising diagnostic tool.

RESUMO

We conducted a double-blind, randomized, placebo-controlled, single-center study involving 30 women undergoing breast augmentation surgery with silicone breast implants. All patients had an A cup breast size and a similar body mass index. We placed the same type of implant in a subpectoral dual plane in each patient. We randomly allocated the study participants to receive either three drops of ginger oil (110 mg Zingiber officinale) or three drops of a placebo control oil placed on their laryngeal mask before insertion. We used a postoperative nausea and vomiting (PONV) and a visual analog scale (VAS) scores as outcome measures and compared the scale results with the dose of morphine used by the patient. The results of the multivariate analysis of variance showed that the ginger oil had a significant effect on PONV/VAS scores, V = 0.87, F(3, 16) = 34.78, p < .001. The results of the univariate analysis of variance showed that using the ginger oil provided significant treatment effects on PONV, F(1, 18) = 73.05, p < .001. These results are also reflected in the descriptive statistics. The mean PONV score for the experimental group and the control group was 1.70 ± 0.48 and 4.20 ± 0.79, respectively. The mean VAS score for the experimental group and the control group was 5.0 ± 1.63 and 5.9 ± 2.33, respectively. The results of our study showed that ginger oil has an important role in preventing PONV and reducing the use of postoperative opioids in women who have undergone breast augmentation surgery.

RESUMO

OBJECTIVES: This study aimed to educate and demonstrate how the use of shear wave elastography (SWE) can be used to determine the elasticity of patient tissues preoperatively, which can then be used to predict the level of lower pole expansion postoperatively, following breast augmentation surgery. MATERIALS AND METHODS: This study evaluated 60 breasts in 30 patients that were divided in 3 equal groups (n = 20) according to their predefined elastography criteria measured via SWE (loose, moderate, and tight tissue elasticity). All measurements were taken under maximum stretch between the inferior border of the nipple alveolar complex (NAC) and inframammary fold (IMF) using a measuring tape in millimetres (mm). The follow-up appointments for routine assessments and measurements were done at 3, 6, 12, 18, and 24 months. RESULTS: The study engaged 38 patients over 4 years, but only 10 patients in each group attended all the appointments. Statistical analysis showed the elastic skin types (loose, moderate, and tight) had significantly different rates of lower pole expansion, and the rate of expansion increased significantly after 6 months postoperatively, whereas prior to 6 months, the rates were comparable (p < 0.05). DISCUSSION: The results showed that increasingly elastic skin types have a greater rate of lower pole expansion. This is important for the operating surgeon to be aware of as looser skin types will be more prone to lower pole expansion, and thus, a higher surgical IMF suture may be advised to manage patient expectations. CONCLUSION: This study can be used as a guideline for surgeons, which will allow for a more predictable surgical planning system that will ultimately lead to fewer revisions and risks for patients worldwide.

RESUMO

Silicone is widely used in chronic implants and is generally perceived to be safe. However, textured breast implants have been associated with immune-related complications, including malignancies. Here, by examining for up to one year the foreign body response and capsular fibrosis triggered by miniaturized or full-scale clinically approved breast implants with different surface topography (average roughness, 0-90 µm) placed in the mammary fat pads of mice or rabbits, respectively, we show that surface topography mediates immune responses to the implants. We also show that the surface surrounding human breast implants collected during revision surgeries also differentially alters the individual's immune responses to the implant. Moreover, miniaturized implants with an average roughness of 4 µm can largely suppress the foreign body response and fibrosis (but not in T-cell-deficient mice), and that tissue surrounding these implants displayed higher levels of immunosuppressive FOXP3+ regulatory T cells. Our findings suggest that, amongst the topographies investigated, implants with an average roughness of 4 µm provoke the least amount of inflammation and foreign body response.

RESUMO

BACKGROUND: Fat grafting in breast augmentation surgery is becoming increasingly popular, allowing surgeons to fill the gaps that implant augmentation alone cannot. However, one of the current issues surrounding fat grafting is the lack of standardization. OBJECTIVES: The objective of this study was to validate and summarize expert-based advice to help plastic surgeons better understand the benefits of utilizing fat grating to reduce implant size in their surgical planning. METHODS: This was a prospective study of fat grafting in 56 patients who underwent fat transfer together with silicone breast implants. A 3-dimensional planning system was used to plan the procedure and also to analyze the fat retention and resorption rates. Pictures served as a basis for a questionnaire in which both patients and physicians were asked to rate their satisfaction. RESULTS: Patients reported a satisfaction rate of "excellent" in 83.3% of cases and "good" in 16.7%. Physician satisfaction was rated as "excellent" in 84.5% of cases, "good" in 13.3%, and "fair" in 4.2% of cases. The mean fat volume grafted per breast was 113.63 mL. The mean absorption rate was 4.53%. CONCLUSIONS: The procedure presented consistent and reproducible results. Hybrid breast augmentation can help design a pathway for a future with breasts free of silicone. This information is particularly relevant for women who have their first breast augmentation at an early age and will probably have 2 to 5 additional surgeries in their lifetime due to the nature of current silicone breast technology.

RESUMO

BACKGROUND: Plastic surgery as a specialty is afflicted with one of the highest incidence rates of thromboembolic events, with abdominoplasty procedures known to assimilate the greatest rates of deep vein thrombosis (DVT). OBJECTIVES: The aim of this study was to develop a prophylactic protocol to reduce the rate of DVT occurrence postabdominoplasty. METHODS: Over a 7-year period 1078 abdominoplasty patients were enrolled onto a holistic 8-point prophylaxis protocol. For a 4-week period before the operation all patients were required to stop smoking, and to cease hormone replacement therapy and combined oral contraception. All patients were required to have a preoperative BMI of less than 40 kg/m2. Participants were supplied with compression stockings, external pumping devices, and enoxaparin. Individuals with a history of DVT were also required to be 1-year treatment free prior to surgery. Furthermore, the protocol required postoperative ambulation of fit patients within 4 hours. RESULTS: Between 2008 and 2013, no incidence of DVT was recorded in all 1078 abdominoplasty surgery patients, indicating the potential for this protocol to lead to a significantly lower incidence than any previously published methodology. Previous studies of DVT incidence were reviewd to identify rates statistically significantly similar to our sample, thereby providing conservative incidence rate estimates. CONCLUSIONS: This 8-point DVT prophylaxis protocol is the first noncriteria-based inclusive protocol aimed at preventing abdominoplasty-associated DVT. A holistic and procedure-specific approach to prophylaxis can drastically reduce the occurrence of DVT in abdominoplasty surgery.With over 116,000 procedures performed annually in the United States, abdominoplasty has become one of the most popular and sought-after surgeries in the plastic and cosmetic field.1 Despite its ever-increasing popularity and the advancement of techniques, abdominoplasty-as with any other surgery-has its complications, including infection, seroma, hematoma, thrombosis, embolism, scarring, and even death. Complication rates as high as 37% have been reported, with some studies reporting a 16% major complication rate.2 One of the most serious and troubling complications for both surgeon and patient is deep vein thrombosis (DVT). With over 1 million patients tested, an estimated 250,000 cases of DVT are diagnosed per year in the United States alone.

RESUMO

Autologous fat transfer is a common technique to refine the contour of the breast after prosthetic augmentation or reconstruction, correcting remaining asymmetries by injecting previously harvested fat tissue with a cannula. Current procedures are often performed without visualization of the cannula at the delivery site and may require subsequent verification of the implant's integrity. The present paper aims to evaluate the safety of a new bulb tip cannula to be used during breast implant procedures for injecting fat adjacent to a breast implant that reduce the risk of damaging the implant. Two conventional cannulae and 3 bulb cannulae, which have an atraumatic distal tip, were tested in a simulated implant-puncture setting in 3 positions (at 0°, 45°, and 90° of incidence). A Tensile Tester (Instron, High Wycombe, UK) was used to apply force with each cannula device and record the amount of force applied in the attempt to penetrate the implants used, with shell layers having a variable thickness. No implant rupture was observed with the bulb tip cannulae regardless of size or the position in which the cannulae were pressed against the implants. The cannula opening was not impeded and tended to bend instead; 27% of the cases with the conventional lipo-cannulae caused an implant rupture. The bulb tip cannula could enhance the safety of the fat transfer procedure by ensuring no iatrogenic implant disruption and optimal delivery of the fat tissue.

RESUMO

BACKGROUND: Although general guidelines are available for established silicone gel breast implants, the unique characteristics of the latest Motiva implants warrant specific guidelines. OBJECTIVES: This study aimed to generate consensus recommendations and summarize expert-based advice to better understand current surgical practices and to establish guidelines for surgeons transitioning from other implant devices to the Motiva implants. METHODS: A survey was compiled by 12 plastic surgeon experts in aesthetic and reconstructive breast surgery and 1 biotechnology scientist, and distributed to 36 plastic surgeons to establish a consensus on the use of these devices. Surgical techniques, complication rates, and implant selection were among the topics discussed. RESULTS: The experts agreed on 3 core principles regarding the use of Motiva Round and Ergonomix implants. Firstly, the dissected pocket needs to be close fitting and steps must be taken to prevent expansion of the pocket. Secondly, implant selection must be individualized. Finally, surgical planning and technique must be carefully considered. When questioned about problems they had ecountered, 84.6% of the experts agreed that they experienced fewer overall complications and 76.9% confirmed reduced capsular contracture rates with these devices. Overall, 84.6% of the experts favored selecting Motiva Ergonomix implants over Round implants to achieve a more natural look. In addition, 92.3% of the experts agreed that Motiva implants, due to their innovative technology, reduce the risk of anaplastic large-cell lymphoma. CONCLUSIONS: This international consensus of leading practitioners will assist plastic surgeons with patient selection, preoperative planning, and surgical technique. These recommendations are designed to optimize surgical outcomes, resulting in lower overall complication rates, more natural-looking breasts, and highly satisfied patients.

RESUMO

BACKGROUND: Silicone breast implants have been in use for breast augmentation for more than 50 years, but technological innovation has been lacking in implant design until recently. OBJECTIVES: This study was designed to evaluate the complication and reoperation rates following breast augmentation utilizing the Motiva silicone breast implants. METHODS: This retrospective study evaluated the safety of Motiva implants in 5813 consecutive cases of breast augmentation. Implants with two different textured surfaces were evaluated: SilkSurface (nanotextured) and VelvetSurface (micro-textured). RESULTS: Implants were placed between April 2013 and April 2016. A total of 44 complications were reported, with an overall complication rate of 0.76%, and the rate of reoperation was 0.76% over an interval of 3 years. There were no late complications and no cases of primary capsular contracture. No differences in complication rates were observed because of the implant date. However, among patients who received implants 300 to 499 cc in volume, complication rates were significantly lower with SilkSurface compared with VelvetSurface implants. Advanced statistical analysis supported the validity of the low complication rate reported in this study. CONCLUSIONS: Overall, these findings suggest that Motiva silicone breast implants are associated with very low rates of complication and reoperation, and that the nano-textured SilkSurface implant is associated with fewer complications than micro-textured implants.

RESUMO

We examined the validity of the Serbian version of the Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King and Henderson-King 2005). A total of 622 Serbian adults completed the ACSS, along with Serbian translations of measures for the discrepancy between actual body weight and ideal body weight, body appreciation, sociocultural attitudes toward appearance, and demographics. Confirmatory factor analyses were conducted to compare how different ACSS models fitted the collected data. A three-factor model provided the best fit to the data relative to two- and one-factor models. The three-factor model had good internal consistency, convergent and discriminant validity, and nomological validity. The ACSS seems to be a valid instrument for use in Serbian populations. Our study will contribute towards better understanding of the acceptance of cosmetic surgery from a cross-cultural perspective.

RESUMO

Great interest remains in finding new and emerging therapies for the treatment of male and female pattern hair loss. The autologous fat grafting technique is >100 years old, with a recent and dramatic increase in clinical experience over the past 10-15 years. Recently, in 2001, Zuk et al published the presence of adipose-derived stem cells, and abundant research has shown that adipose is a complex, biological active, and important tissue. Festa et al, in 2011, reported that adipocyte lineage cells support the stem cell niche and help drive the complex hair growth cycle. Adipose-derived regenerative cells (also known as stromal vascular fraction [SVF]) is a heterogeneous group of noncultured cells that can be reliably extracted from adipose by using automated systems, and these cells work largely by paracrine mechanisms to support adipocyte viability. While, today, autologous fat is transplanted primarily for esthetic and reconstructive volume, surgeons have previously reported positive skin and hair changes posttransplantation. This follicular regenerative approach is intriguing and raises the possibility that one can drive or restore the hair cycle in male and female pattern baldness by stimulating the niche with autologous fat enriched with SVF. In this first of a kind patient series, the authors report on the safety, tolerability, and quantitative, as well as photographic changes, in a group of patients with early genetic alopecia treated with subcutaneous scalp injection of enriched adipose tissue. The findings suggest that scalp stem cell-enriched fat grafting may represent a promising alternative approach to treating baldness in men and women.
