Self-reported systemic symptoms among women with breast implants.

Around 2,500 women receive a breast augmentation with silicone-based implants yearly in Denmark. A number of these women report various uncharacteristic systemic symptoms, which they attribute to the breast implants, including impaired cognition, joint pain, etc. This condition has been termed "breast implant illness" and is currently not a recognised diagnosis. The correlation between the patient's self-reported symptoms and breast implants has not been established and there is limited evidence that surgery has any effect. In this review, the current literature on the topic has been reviewed.

Unnecessary Explantation of IDEAL IMPLANT Structured Saline Breast Implants Prompted byRadiologic Misdiagnosis of Rupture.

ABSTRACT: The unique dual-lumen and baffle design of the IDEAL IMPLANT Structured Saline breast implant gives it specific advantages over both silicone gel-filled and the original saline-filled implants. This internal baffle structure also gives it an appearance on various radiologic imaging studies that may be misinterpreted as a rupture because of similarities to the well-known radiologic appearance of a ruptured silicone gel implant. Patients may present with various misinterpreted imaging studies, highlighting the need for plastic surgeons and radiologists to be familiar with the normal appearance of the intact IDEAL IMPLANT and be able to distinguish it from a ruptured IDEAL IMPLANT. The radiology findings must be correlated with the clinical findings, or an intact IDEAL IMPLANT misdiagnosed as ruptured, may cause unnecessary patient worry, and may prompt unnecessary surgery for removal or replacement.

Immediate Breast Reconstruction With Latissimus Dorsi Myocutaneous Flap and Silicone Implant Followed by Adjuvant Radiotherapy for Breast Cancer.

BACKGROUND: About 30% to 50% of women with breast cancer undergo mastectomy, and approximately 50% of them will receive adjuvant radiotherapy (ART). This study evaluates the medium- and long-term impact of ART after immediate breast reconstruction (IBR) with latissimus dorsi myocutaneous (LDM) flap and silicone implants. METHODS: Clinical, surgical, and oncological data were retrospectively collected and analyzed based on the medical records of 176 patients who had undergone IBR with LDM flap and silicone implants. RESULTS: The data showed that 7.4% of patients had a history of previous radiotherapy, 56.3% received ART, 31.8% developed capsular contracture with a mean follow-up of 58.1 months, and 14.2% of surgeries were categorized as procedures with a prolonged operating time, lasting above 1 SD of the observed mean. Those who experienced prolonged operating time (odds ratio, 4.72; 95% confidence interval, 1.72-12.93; P = 0.003) and those who received ART (odds ratio, 7.38; 95% confidence interval, 3.18-17.10; P < 0.001) were more likely to develop capsular contracture. Thirty-two patients (18%) underwent capsulectomy with implant replacement, and 7 patients (4%) had the implant removed. The mean time between IBR and reoperation was 29.1 months. Patients who received ART were 2.84 times more likely to experience reconstruction failure or undergo implant-related reoperation ( P = 0.002). CONCLUSIONS: The results indicated that IBR with LDM flap and silicone implant followed by ART is a safe procedure, resulting in low rates of reconstruction failure. However, ART increased the likelihood of capsular contracture development and implant-related reoperation, having a negative effect on reconstructed breasts.

Altered Foreign Body Response at the Posterior Surface Compared to the Anterior Surface of Human Silicone Breast Implants.

Soft implantable devices are crucial to optimizing form and function for many patients. However, periprosthetic capsule fibrosis is one of the major challenges limiting the use of implants. Currently, little is understood about how spatial and temporal factors influence capsule physiology and how the local capsule environment affects the implant structure. In this work, we analyzed breast implant capsule specimens with staining, immunohistochemistry, and real-time polymerase chain reaction to investigate spatiotemporal differences in inflammation and fibrosis. We demonstrated that in comparison to the anterior capsule against the convex surface of breast implants, the posterior capsule against the flat surface of the breast implant displays several features of a dysregulated foreign body reaction including increased capsule thickness, abnormal extracellular remodeling, and infiltration of macrophages. Furthermore, the expression of pro-inflammatory cytokines increased in the posterior capsule across the lifespan of the device, but not in the anterior capsule. We also analyzed the surface oxidation of breast explant samples with XPS analysis. No significant differences in surface oxidation were identified either spatially or temporally. Collectively, our results support spatiotemporal heterogeneity in inflammation and fibrosis within the breast implant capsule. These findings presented here provide a more detailed picture of the complexity of the foreign body reaction surrounding implants destined for human use and could lead to key research avenues and clinical applications to treat periprosthetic fibrosis and improve device longevity.

A randomised investigation of film-forming silicone gel in superficial partial thickness face and neck burn patients: Indication of improved early scar pigmentation outcomes.

INTRODUCTION: Burns to the face and neck are a source of considerable distress and a challenge to manage with dressings. Further, these often superficial injuries pose a risk of scarring and altered pigmentation. Silicone gels have emerged as a potential solution to the challenges of conservative management for face and neck burn injuries. The aims of this study were to explore the effect of topical silicone compared to routine treatment of conservatively managed burns to the face and neck. METHODS: This single-blind, randomised, controlled trial compared topical silicone film-forming dressing to standard of care for superficial partial thickness burns to the face and neck. Time to healing was the primary outcome and secondary outcomes included: 1) scar assessments (modified Vancouver Scar Scale, Dermalab Combo and Patient and Observer Scar Assessment Scale) at six weeks and three months; and 2) pain intensity scale at wound review appointments. RESULTS: Of the 55 participants in the face/neck study, 34 were male and 21 were female. Median age was 36 years (range from 25 to 47 years). The median time to healing for the silicone group was 9 days (CI 7.6 -10.4) and the control group was 7 days (CI 5.3- 8.7), p = 0.056. Analysis demonstrated significantly reduced pigmentation at six weeks in mVSS scores for the silicone group (Md = 0, IQR = 0) compared to the control group (Md = 0, IQR = 0 - 3), p = 0.043. We found no evidence of differences in reported pain between the groups (Silicone - Md = 1.15, IQR 0.3 - 4.5 vs control group - Md = 1.5, IQR 0.6 - 3.8, z = -0.63, p = 0.53). No other differences were observed, and no adverse events were associated with the topical silicone in the study whereas an infection and a reaction were experienced in the control group. CONCLUSION: Film-forming silicone gel had comparable effects to standard of care emollient on wound healing of superficial partial thickness burns of the face and neck. Silicone treated wounds were associated with a significant improvement in scar pigmentation outcome at six weeks post-burn.

Major Clinical Adverse Events of Breast Implant in the Manufacturer and User Facility Device Experience Database.

OBJECTIVE: Search the Manufacturer and User Facility Device Experience database to collect information on adverse events of breast implant. We analyzed the local complications and the breast implant illness (BII) of silicone breast implants, as well as saline breast implants separately, aim to provide a reference for women who want to breast augmentation. MATERIALS AND METHODS: The Manufacturer and User Facility Device Experience database was queried for events reports related to the breast implant between July 1, 2012, and June 30, 2022. Event year and reporting year were summarized. Patient problem was collected and analyzed to distinguish between local complications and BII. RESULTS: A total of 108,728 adverse events in the past 3 years were analyzed, silicone breast implants accounted for 62.1% and saline breast implants accounted for 37.9%. The most common local complication of women receiving silicone breast implants was "Capsular Contracture," accounting for 48.73%. However, the incidence of "capsular contracture" in women who received saline breast implants was only 17.49%. The most common BII was "fatigue/weakness" in both women receiving 2 different breast implants, 17.20% in women receiving silicone breast implants and 24.71% in women receiving saline breast implants. Of note, in all the reports, there was a wide variation in the timing of reporting as compared with the timing of the adverse event. CONCLUSIONS: Although the adverse events of breast implant cannot completely be determined from this study, we provide a reference for women who want to get breast implants, so that they can choose breast implants more carefully. In addition, a better understanding of BII may allow them to think further about whether the benefits of breast implants outweigh the risks.

Prevalence, clinical characteristics, and management of silicone lymphadenopathy: A systematic review of the literature.

INTRODUCTION: Implant-based breast augmentations and reconstructions are one of the most common surgical procedures performed by plastic surgeons in the United States, which has rapidly increased in popularity since the 2000s. Silicone lymphadenopathy (SL) is a complication of breast implants that involves migration of silicone to nearby soft tissue/lymph nodes. Data on its clinical features and management is scarce. METHODS: SL-related search terms were used to find articles in 3 databases. Of 598 articles, 101 studies met the inclusion criteria. Demographics, clinical presentation, workup, and management data were analyzed. RESULTS: Of 279 cases of SL and 107 with information on initial diagnosis, 35 (33%) were incidental. The most common symptom was painless lymphadenopathy, followed by painful lymphadenopathy. 251 (95%) and 13 (5%) patients had silicone and saline implants, respectively. 149 (68%) patients had implant rupture. Axillary lymphadenopathy was the most affected region (136 cases, 72%), followed by internal mammary (40 cases, 21%), cervical/supraclavicular (36 cases, 19%), and mediastinal (24 cases, 13%) regions. 25% of patients underwent fine-needle aspiration, 12% core needle biopsy, and 59% excisional biopsy. 32% of cases underwent explantation and/or implant exchange. The most common indication for surgery was implant rupture. Histology showed multinucleated giant cells, large histiocytes, and silicone accumulation. CONCLUSIONS: SL is a complication associated with breast implants. The majority of patients are asymptomatic, and most cases are managed conservatively. Minority need a biopsy and surgical interventions due to abnormal imaging, persistent symptoms, and/or implant rupture. Workup and management should be tailored to the patient.

The Effect of 3-Dimensional-Printed Sequential Dual Drug-Releasing Patch on the Capsule Formation Around the Silicone Implant in a Rat Model.

BACKGROUND: Implant-based breast reconstruction is associated with increased risk of early infection and late-stage capsular contracture. OBJECTIVES: We evaluated the feasibility of a dual drug-releasing patch that enabled the controlled delivery of antibiotics and immunosuppressants in a temporally and spatially appropriate manner to the implant site. METHODS: The efficacy of a dual drug-releasing patch, which was 3-dimensional-printed (3D-printed) with tissue-derived biomaterial ink, was evaluated in rats with silicone implants. The groups included implant only (n = 10); implant plus bacterial inoculation (n = 14); implant, bacterial inoculation, and patch loaded with gentamycin placed on the ventral side of the implant (n = 10), and implant, bacterial inoculation, and patch loaded with gentamycin and triamcinolone acetonide (n = 9). Histologic and immunohistochemical analyses were performed 8 weeks after implantation. RESULTS: The 2 drugs were sequentially released from the dual drug-releasing patch and exhibited different release profiles. Compared to the animals with bacterial inoculation, those with the antibiotic-only and the dual drug-releasing patch exhibited thinner capsules and lower myofibroblast activity and inflammation, indicating better tissue integration and less foreign body response. These effects were more pronounced with the dual drug-releasing patch than with the antibiotic-only patch. CONCLUSIONS: The 3D-printed dual drug-releasing patch effectively reduced inflammation and capsule formation in a rat model of silicone breast reconstruction. The beneficial effect of the dual drug-releasing patch was better than that of the antibiotic-only patch, indicating its therapeutic potential as a novel approach to preventing capsular contracture while reducing concerns of systemic side effects.

Pressure-garment therapy for preventing hypertrophic scarring after burn injury.

BACKGROUND: Burn damage to skin often results in scarring; however in some individuals the failure of normal wound-healing processes results in excessive scar tissue formation, termed 'hypertrophic scarring'. The most commonly used method for the prevention and treatment of hypertrophic scarring is pressure-garment therapy (PGT). PGT is considered standard care globally; however, there is continued uncertainty around its effectiveness. OBJECTIVES: To evaluate the benefits and harms of pressure-garment therapy for the prevention of hypertrophic scarring after burn injury. SEARCH METHODS: We used standard, extensive Cochrane search methods. We searched CENTRAL, MEDLINE, Embase, two other databases, and two trials registers on 8 June 2023 with reference checking, citation searching, and contact with study authors to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing PGT (alone or in combination with other scar-management therapies) with scar management therapies not including PGT, or comparing different PGT pressures or different types of PGT. DATA COLLECTION AND ANALYSIS: At least two review authors independently selected trials for inclusion using predetermined inclusion criteria, extracted data, and assessed risk of bias using the Cochrane RoB 1 tool. We assessed the certainty of evidence using GRADE. MAIN RESULTS: We included 15 studies in this review (1179 participants), 14 of which (1057 participants) presented useable data. The sample size of included studies ranged from 17 to 159 participants. Most studies included both adults and children. Eight studies compared a pressure garment (with or without another scar management therapy) with scar management therapy alone, five studies compared the same pressure garment at a higher pressure versus a lower pressure, and two studies compared two different types of pressure garments. Studies used a variety of pressure garments (e.g. in-house manufactured or a commercial brand). Types of scar management therapies included were lanolin massage, topical silicone gel, silicone sheet/dressing, and heparin sodium ointment. Meta-analysis was not possible as there was significant clinical and methodological heterogeneity between studies. Main outcome measures were scar improvement assessed using the Vancouver Scar Scale (VSS) or the Patient and Observer Scar Assessment Scale (POSAS) (or both), pain, pruritus, quality of life, adverse events, and adherence to therapy. Studies additionally reported a further 14 outcomes, mostly individual scar parameters, some of which contributed to global scores on the VSS or POSAS. The amount of evidence for each individual outcome was limited. Most studies had a short follow-up, which may have affected results as the full effect of any therapy on scar healing may not be seen until around 18 months. PGT versus no treatment/lanolin We included five studies (378 participants). The evidence is very uncertain on whether PGT improves scars as assessed by the VSS compared with no treatment/lanolin. The evidence is also very uncertain for pain, pruritus, adverse events, and adherence. No study used the POSAS or assessed quality of life. One additional study (122 participants) did not report useable data. PGT versus silicone We included three studies (359 participants). The evidence is very uncertain on the effect of PGT compared with silicone, as assessed by the VSS and POSAS. The evidence is also very uncertain for pain, pruritus, quality of life, adverse events, adherence, and other scar parameters. It is possible that silicone may result in fewer adverse events or better adherence compared with PGT but this was also based on very low-certainty evidence. PGT plus silicone versus no treatment/lanolin We included two studies (200 participants). The evidence is very uncertain on whether PGT plus silicone improves scars as assessed by the VSS compared with no treatment/lanolin. The evidence is also very uncertain for pain, pruritus, and adverse events. No study used the POSAS or assessed quality of life or adherence. PGT plus silicone versus silicone We included three studies (359 participants). The evidence is very uncertain on the effect of PGT plus silicone compared with silicone, as assessed by the VSS and POSAS. The evidence is also very uncertain for pain, pruritus, quality of life, adverse events, and adherence. PGT plus scar management therapy including silicone versus scar management therapy including silicone We included one study (88 participants). The evidence is very uncertain on the effect of PGT plus scar management therapy including silicone versus scar management therapy including silicone, as assessed by the VSS and POSAS. The evidence is also very uncertain for pain, pruritus, quality of life, adverse events, and adherence. High-pressure versus low-pressure garments We included five studies (262 participants). The evidence is very uncertain on the effect of high pressure versus low pressure PGT on adverse events and adherence. No study used the VSS or the POSAS or assessed pain, pruritus, or quality of life. Different types of PGT (Caroskin Tricot + an adhesive silicone gel sheet versus Gecko Nanoplast (silicone gel bandage)) We included one study (60 participants). The evidence is very uncertain on the effect of Caroskin Tricot versus Gecko Nanoplast on the POSAS, pain, pruritus, and adverse events. The study did not use the VSS or assess quality of life or adherence. Different types of pressure garments (Jobst versus Tubigrip) We included one study (110 participants). The evidence is very uncertain on the adherence to either Jobst or Tubigrip. This study did not report any other outcomes. AUTHORS' CONCLUSIONS: There is insufficient evidence to recommend using either PGT or an alternative for preventing hypertrophic scarring after burn injury. PGT is already commonly used in practice and it is possible that continuing to do so may provide some benefit to some people. However, until more evidence becomes available, it may be appropriate to allow patient preference to guide therapy.

Submuscular Buttock Augmentation With Silicone Implants in 80 Female Patients.

BACKGROUND: Over the past 4 decades, gluteal augmentation has increased enormously in popularity, and numerous techniques have been developed to provide patients with the best possible outcomes. The submuscular technique has been shown to be a reliable option for a broad cohort of patients. OBJECTIVES: The main objective of this retrospective study was to describe the characteristics and clinical outcomes of a group of patients who underwent gluteal augmentation by the submuscular technique. METHODS: A retrospective analysis was conducted on 80 female patients who underwent submuscular gluteal augmentation with silicone implants between August 2019 and May 2022. All of the patients were operated on by the authors of the present study. RESULTS: Information about patient demographics, implants, complications, and treatments was analyzed. Moreover, the satisfaction of the patients was assessed by means of a short survey. The most frequent complication was wound dehiscence. Only 7 patients required surgical revisions, and 2 required isolated antibiotic therapy. All complications were effectively addressed and no implants had to be removed. Furthermore, the retrospective analysis revealed a noteworthy association between the size of the implant and the occurrence of complications. CONCLUSIONS: The submuscular method provides the best aesthetic results and adequate safety for patients. It significantly minimizes the possibility of complications, such as fluid collection due to muscle fiber dissection or implant exposure/extrusion.

Ultrasonographic Identification of Shell Surface Types in Commercially Available Silicone Gel-Filled Breast Implants.

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.

Silicone Particles in Capsules Around Breast Implants: An Investigation Into Currently Available Implants in North America.

BACKGROUND: Breast implants have always been composed of a silicone elastomer envelope filled with either silicone gel or saline. Breast implant illness (BII) is a set of symptoms that has previously been linked to the leakage of silicone particles from the implants into the body. OBJECTIVES: Our research aimed to quantify the number of silicone particles present in the capsules of breast implants available in North America. METHODS: Thirty-five periprosthetic capsules were sampled and analyzed, and silicone particles were counted and measured. The capsule surface area was then measured and utilized to calculate particle density and total number of silicone particles. RESULTS: Eighty-five percent of capsules analyzed from silicone gel implants contained silicone, with an average of 62 particles per mm3 of capsular tissue. These implants had approximately 1 million silicone particles per capsule. In contrast, none of the saline implant capsules contained silicone. Capsules from macrotextured tissue expanders contained fewer and larger silicone particles. CONCLUSIONS: Silicone gel implants presented silicone particle bleeding into the periprosthetic capsule, totaling on average 1 million silicone particles per capsule. On the other hand, no silicone particle bleeding was observed from saline breast implants. These data suggest that particle bleeding comes from the inner silicone gel, and not from the smooth outer silicone shell. Previous studies have reported the presence of breast implant illness in patients with both silicone- and saline-filled implants. Therefore, our data suggest that silicone migration is not the sole cause of BII.

Outcome analysis and assessment of the lower pole expansion following breast augmentation with ergonomic implants: Optimizing results with patient selection based on 5-year data.

BACKGROUND: Silicone implants have gone through adaptations to improve esthetic outcomes. With the progress of technology, including gel rheology, different properties have been introduced. Ergonomic style implants (ESI) feature enhanced rheological properties and provide a shaped contour with a round base. OBJECTIVES: This study investigated outcomes for ESI in breast augmentation concerning lower pole stretching (LPS) and implant stability and describes an algorithm to assist in decision-making. METHODS: A total of 148 patients (296 breasts) underwent breast augmentation with ESI; this procedure was indicated in patients with good skin quality and <6 cm between the nipple-areola complex and the inframammary fold. RESULTS: The mean patient age was 29.6 years (range: 19-39), and 93 patients (62.8%) underwent primary breast augmentation with demi/full projection (average volume of 245 cc [175-375 cc]). Axillary incision and subfascial pocket were indicated in 115 (77.7%) and 72 (48%) cases, respectively. Average LPS values were 32.2% (24.91 mm) and 10.86% (9.42 mm) at up to 10 days and 10 days to 12 months postprocedure, respectively. Patients were followed for a mean of 29.9 ± 26.4 months (range: 6-66). Complication rates per breast and per patient were 5% and 10%, respectively, and included subcutaneous banding in the axilla (1.6%), implant displacement (1.2%), and wound dehiscence (0.8%). No cases of infection, seroma, or rippling complications were observed. CONCLUSIONS: The present decision-making algorithm summarizes the process involved in breast augmentation using ESI and is intended to help standardize decisions. With correct planning, long-lasting outcomes can be achieved due to favorable interactions between ESI and the patient's tissues.

Updated trends of breast implant surgeries: An Israeli analysis.

INTRODUCTION: Breast augmentation remains one of the most prevalent procedures in plastic surgery. While most patients experience high satisfaction with the outcomes, a subset may encounter various complications or dissatisfaction with achieved results necessitating subsequent surgical intervention including implant removal or exchange. MATERIALS AND METHODS: We collected information from three pivotal private medical centers in Israel where a considerable number of breast surgeries are performed. We examined the number of breast augmentations, implant exchange and implant removal surgeries with or without breast lift that were performed on a biannual basis for each center for the period 2018-2022. Trends in surgery types were analyzed and compared to registries in other countries. RESULTS: Between the years 2018 and 2022, 20,075 surgeries were done in three main private medical centers in Israel. Data show a gradual increase in implant removal surgeries from 2018 (n = 80, 2.9%) to 2019 (n = 269, 9.9%), followed by a significant increase in 2020 (n = 1436, 27.3%), and a gradual decline between 2021 (n = 1019, 22.8%) and 2022 (n = 916, 18.5%). The overall number of breast implant insertion procedures (breast augmentation procedures and exchange procedures) was 2659 in 2018 (97%), 2424 in 2019 (90.0%), 3816 in 2020 (72.6%), 3437 in 2021 (77.1%), and 4019 in 2022 (81.4%). SUMMARY: We present updated trends in breast implant surgeries in Israel. 2020 was a key year in which the rate of explantations was the highest, and the percentage rate of implantations was the lowest and a year in which the trend changed. These patterns partly align with trends seen in other countries worldwide.

A systematic review of the management of postoperative scars with silicone gel-based products in randomized controlled trials.

Although postoperative scarring may be considered a cosmetic concern, it can greatly impact a patient's quality of life. This extends beyond psychosocial burden influenced by hypertrophic scars and keloids, as patients also experience discomfort and pain. This systematic review evaluates the efficacy of silicone gel (SG)-based products in preventing postoperative abnormal scar formation. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a PubMed search was performed to find randomized, controlled trials investigating the effect of SG-based products on postoperative wound healing. The search yielded 359 publications, but only 30 studies published between 1991-2022 were found to fit the inclusion criteria. Outcomes were extracted from the literature and subsequent quality and risk of bias assessments were performed. Most studies indicated improvement of at least one quality of the scar with the use of SG-based products. The greatest potential variable increasing bias was an inadequate control group. Studies also suffered from small sample sizes, use of unvalidated scar assessment scales, lack of double-blinding, and short follow-up periods. Overall, SG-based products demonstrated potential in preventing abnormal scar formation during postoperative healing, but further studies are required to validate the results of current literature.

Micro-plasma radiofrequency and silicone gel dressings for treating early post-traumatic facial scars: A retrospective study.

BACKGROUND: Although different options are available for treating post-traumatic facial scars, they remain a therapeutic challenge. AIM: To evaluate the safety and effectiveness of combined therapy using micro-plasma radiofrequency (MPRF) technology and silicone gel (SG) dressings for treating post-traumatic facial scars. METHODS: This retrospective study was conducted at a single center. Patients with facial injuries in the outpatient and emergency units of the Department of Plastic Surgery at our hospital underwent debridement and cosmetic sutures performed by the same surgeon from October 2020 to October 2021. In the first arm, patients with facial injuries were treated with MPRF technology and SG, and in the second arm, they were treated with SG dressings alone. We observed the safety and effectiveness of these treatments in both arms. RESULTS: A total of 32 patients with facial injuries were treated with MPRF technology and SG dressings (combined treatment group), and 28 patients were treated with SG dressings alone (SG group). After 6 months of treatment, the Vancouver Scar Scale scores of the combined treatment and SG groups were 1.38 ± 0.71 and 4.39 ± 0.50, respectively, and the difference was statistically significant (P < 0.01). After 6 months of treatment, the effectiveness rate in the combined treatment group was 93.8%, which was significantly higher than that in the SG group (67.9%), and the difference between the two groups was statistically significant (P < 0.05). No obvious adverse reactions occurred in the two arms. CONCLUSION: Treating early post-traumatic facial scars with combined MPRF technology and SG is significantly better than treating them with SG alone; moreover, the combined therapy is safe and effective.

Rupture of 40-year-old silicone gel breast implants: a case report.

BACKGROUND: Implant rupture is one of the complications of breast augmentation surgery. The rupture of silicone implants is often insidious, potentially causing problems at any time. This is a case report of the rupture of 145-cc breast implants manufactured by Dow Corning Corporation and their removal at 40 years after augmentation. CASE PRESENTATION: A 70-year-old female patient was admitted for the removal of a lump in the upper and inner quadrants of the right breast. After a detailed examination, a rupture of the bilateral breast implants was diagnosed. Explantation without replacement was performed; the entire procedure proceeded smoothly. Immunohistochemical staining revealed siliconoma with lymphoid hyperplasia and calcification in the bilateral breasts with no signs of malignancy. CONCLUSIONS: Silicone breast augmentation is one of the most popular aesthetic surgical procedures worldwide. Therefore, it is important to educate patients on the need for close monitoring of their implants after augmentation through magnetic resonance imaging or ultrasound to facilitate early detection of any changes before a rupture occurs. Early detection of the implant rupture, in turn, will facilitate early and effective management.
