Keloid and Hypertrophic Scars Treatment.

BACKGROUND: Hypertrophic scars are contained within the site of injury and may regress over time, while keloids spread beyond the borders of the initial injury and do not regress. On histologic examination, hypertrophic scars tend to have collagen in a wavy, regular pattern, whereas keloids have no distinct pattern of collagen. OBJECTIVE: To retrospectively analyze improvement in keloid and hypertrophic scars characteristics following treatment with Ablative 10600 nm and a non-Ablative 1570 nm Hybrid Laser Device. METHODS: Treatment parameters with the ProScan Hybrid Mode were 40 W/1.3-1.5 ms for the CO2 and 12 W/4 ms for the 1570 nm in a 1:1 ratio. Outcomes were assessed based on physician scar grading as measured by the Vancouver Scar Scale and patient-reported satisfaction. Excel was used for data analysis, and a p value < 0.05 was considered statistically significant. Adverse events and patient pain were also recorded. RESULTS: A total of 31 hypertrophic scars and 30 keloid scars were treated. There was a significant reduction in Vancouver Scar Scale scores for both hypertrophic and keloid scars (62% ± 8% and 58% ± 7%; p = 2.6E-17 and p = 8.29E-26, respectively). In a scar-based comparison, a statistically significant difference was observed for all measures reflecting favorable outcomes for hypertrophic scars (VSS, p = 1.1E-05; satisfaction, p = 0.0112; pain, p = 0.00081). Only one adverse event was reported, a superficial burn treated with topical antibiotics. CONCLUSIONS: The device was found to be safe and effective, with promising results for the treatment of hypertrophic and keloid scars.

Silicone Lymphadenopathy Following Augmentation Mammoplasty With Silicone Implants.

BACKGROUND: Silicone implants are by far the most widely used implant globally for breast augmentation. Despite technological advancements, complications persist, with silicone lymphadenopathy (siliconoma) being a noteworthy concern. This phenomenon has been inadequately addressed in the existing literature. OBJECTIVES: The aim of this study was to characterize axillary siliconomas and identify potential risk factors to help reduce their occurrence. METHODS: The authors conducted a retrospective observational cross-sectional study spanning between 2011 and 2021 at the Shamir Assaf Harofeh Medical Center, Israel. Preoperative ultrasound examination was conducted, categorizing patients into those with siliconomas and those without. RESULTS: A total of 614 women (1209 breasts) met the inclusion criteria. The incidence of siliconomas was 13.6% (165 breasts). In univariate analysis, older age (47 years vs 43 years, P < .001), older implant age (12.2 years vs 11 years, P = .026), ruptured implants (59.4% vs 17.7%, P < .001), subpectoral placement (P = .019), severe capsular contracture, and the use of Mentor implants (Irvine, CA; P = .007) and Poly Implant Prothèse implants (PIP; La Seyne-sur-Mer, France; P = .001) correlated significantly with the presence of siliconomas. In a multivariate analysis, implant rupture (odds ratio [OR] = 6.342), and implant manufacturer-Mentor (OR = 3.047) and PIP (OR = 3.475)-were identified as independent risk factors associated with a higher incidence of siliconomas. Severe capsular contracture was also associated with a higher incidence of siliconomas (OR = 1.65). CONCLUSIONS: Surgeons should inform candidates about the potential risk of silicone migration. Patients with ruptured implants, significant capsular contracture, and Mentor and PIP implants face an increased risk for developing siliconomas. Closer monitoring for the detection of siliconomas in the axilla for these patients is advisable, and potential prophylactic replacement or removal of implants may be warranted to mitigate siliconoma risk.

High-Quality Lipoaspirate Following 1470-nm Radial Emitting Laser-Assisted Liposuction.

BACKGROUND: Laser-assisted liposuction (LAL) has been used to maximize viable adipocyte yields in lipoaspirates, although optimizing tissue processing methods is still a challenge. A high-quality lipoaspirate has been a key factor for extended graft longevity. OBJECTIVE: To assess the viability and potency of stromal vascular fraction (SVF) cells and adipose-derived stem cells (ASCs) in fat samples from lipoaspirates harvested with a novel 1470-nm diode, radial emitting LAL platform. Two processing methods, enzymatic and nonenzymatic, were compared. METHODS: Laser-assisted liposuction lipoaspirates harvested from 10 subjects were examined for cell viability after processing by enzymatic or nonenzymatic methods. Isolated SVF cells were cultured with an ASC-permissive medium to assess their viability and proliferation capacity by cell proliferation assay. Flow cytometric analysis with ASC-specific markers, gene expression levels, and immunofluorescence for ASC transcription factors were also conducted. RESULTS: Lipoaspirates showed high SVF cell viability of 97% ± 0.02% and 98% ± 0.01%, averaged SVF cell count of 8.7 × 10 6 ± 3.9 × 10 6 and 9.4 × 10 6 ± 4.2 × 10 6 cells per mL, and averaged ASC count of 1 × 10 6 ± 2.2 × 10 5 and 1.2 × 10 6 ± 5 × 10 5 cells per mL in nonenzymatic and enzymatic methods, respectively. The ASC-specific markers, gene expression levels, and immunofluorescence for ASC transcription factors confirmed the adipose origin of the cells. CONCLUSIONS: The laser lipoaspirates provide a high yield of viable and potent SVF cells and ASCs through both nonenzymatic and enzymatic processes. Improved purity of the harvested lipoaspirate and high ASC content are expected to result in extended graft longevity. Furthermore, eliminating enzymatic digestion may provide advantages, such as reducing process time, cost, and regulatory constraints.

Social Media as a Tool to Educate Plastic Surgeons on Patients' Concerns Before and After Cosmetic Breast Surgeries.

BACKGROUND: The rapid evolution of the social media platform has had a major effect on the field of medicine. OBJECTIVE: To identify patterns, trends and patients' concerns before and after aesthetic surgeries involving breast implants, by analyzing social media posts. METHODS: We examined comments posted on popular Israeli online public forums between January 2019 and May 2021, regarding: breast augmentation, mastopexy-augmentation and breast implant removal. RESULTS: During the study period, 561 comments were posted on the three forums investigated: 165 pre-operative and 396 post-operative. In the pre-operative period, the main interests were implant size, type and location, as discussed in 69 posts (42%). During the first two months post-operative, questions reflected concerns regarding post-operative instructions, wound management and asymmetry: 76 (43%), 59 (34%) and 27 (16%), respectively. These topics continued to be in focus up to one year post-operative. Beyond the first post-operative year, patients' main interests were breast implant-associated anaplastic large cell lymphoma (25 posts, 28%), capsule formation (23 posts, 26%) and systemic effects (23 posts, 26%). CONCLUSIONS: Social media harnessing to identify patterns, trends and patient concerns pre- and post-aesthetic breast surgeries is a novel approach. Misinformation was common, particularly in comments posted more than one year post-operative. Four topics that especially concerned patients in the immediate and late post-operative period were asymmetric results, breast implant-associated anaplastic large cell lymphoma, capsule removal and systemic effects. We advise surgeon and plastic surgeon societies to issue position papers on controversial subjects, to counter the dissemination of potentially misleading information.

Pregnancy Reverses Abdominoplasty Aesthetic Outcome: Myth or Misconception? A Cross-Sectional Study.

BACKGROUND: The common recommendation for female abdominoplasty candidates is to conclude family planning before undergoing the procedure. However, no evidence demonstrates a correlation between aesthetic outcome compromise, risk for fetal complications, or risk for maternal complications when abdominoplasty is followed by pregnancy. OBJECTIVES: The aim of this study was to evaluate maternal, fetal, and aesthetic outcomes among pregnant females with a history of abdominoplasty. METHODS: The authors conducted an online survey among women who became pregnant after having an abdominoplasty. Participants were recruited via social media groups related to abdominoplasty. The survey included demographic-, aesthetic outcome-, and pregnancy-related questions utilizing a score from 1 (no effect) to 10 (worst effect) to assess abdominal aesthetic outcome compromise. RESULTS: Thirty-two participants completed the online survey, 15 (46.8%) of which reported their pregnancy was unplanned. Pregnancy-related findings included 5 (15.6%) late premature births (between gestational week 35 and 37), 1 miscarriage, and 1 emergency C-section. Compromised aesthetic outcomes following pregnancy included new abdominal stretch marks (50%, N = 16), widened abdominoplasty scar (28%, N = 9), abdominal skin excess (37.5%, N = 12), and abdominal bulge (25.8%, N = 8). A new hernia was reported by 2 participants (6.3%). The average abdominal aesthetic severity score was 2.7 (range, 1-8), and only 3 scores were above 5 (9.3%). Two women (6.2%) underwent abdominoplasty revision, and 18 (56.2%) stated they would recommend others to undergo abdominoplasty before pregnancy (56.3%). CONCLUSIONS: This survey shows there is room to reevaluate whether future pregnancy should be considered a relative contraindication for undergoing abdominoplasty.

Breast Implantation Rates in Israel: Is There a Change in Trend?

BACKGROUND: Breast implant illness (BII) is a rising concern among many patients. Although not fully understood, a connection between silicone breast implants and systemic diseases may be present. This connection may influence the types of breast surgeries performed. OBJECTIVES: To evaluate changing trends in breast surgeries in Israel over time, with regard to implantation, explantation, and implant exchange surgeries. METHODS: In this ecological study, we presented data from four private medical centers in Israel regarding the number of breast implant surgeries performed in the years 2018-2019. Data were collected bi-yearly. The types of surgeries included breast implantation, explantation, and breast implant exchange. RESULTS: When we summed and compared the yearly data, we saw that the number of implantations in 2018 was 2267 (80.1% of breast implant procedures that year), and 1929 (68.9%) in 2019. The number of implant exchanges in 2018 and 2019 was 482 (17.0%) and 608 (21.7%), respectively. In 2018, 80 (2.8%) explantations were performed and 262 (9.4%) in 2019. CONCLUSIONS: There appears to be a trend in the rise of implant removal surgeries in addition to a decrease in breast implantations. One possible reason may be patient concerns of BII. Another reason may be the increased public interest and discussion about systemic effects of breast implants. More research is needed in this field to achieve better understanding of the phenomenon, the reasons behind it, and the possible solutions and ways of treatment.

Inferiorly Based Preauricular Flap for Anterior Ear Reconstruction.

BACKGROUND: The anterior aspect of the auricle is a complex 3-dimensional structure. Each anatomical component in this region has an essential role in the aesthetic appearance of the ear and face. The reconstruction of defects in this region is challenging because of the lack of mobile, excess skin for primary closure, and the inability to skin graft overexposed cartilage. OBJECTIVE: The aim of the study was to present the planning and surgical technique of a simple, reproducible, 1-stage flap, for the reconstruction of the anterior aspect of the auricle. PATIENTS AND METHODS: A series of 11 patients, who underwent reconstruction of the anterior aspect of the auricle with 1-stage, inferiorly based, preauricular, cutaneous flap. All reconstructions were conducted under local anesthesia, and the defects were mainly due to tumor resections or skin necrosis after otoplasty. The average defect size was 1.5 cm. The flap was applied to different sites of the anterior auricle. RESULTS: All flaps survived except one, where there was partial flap loss. The aesthetic results were excellent, with no auricular deformity. CONCLUSIONS: The inferiorly based, preauricular flap is a versatile flap for a safe, simple, and reproducible, 1-stage reconstruction for almost every region of anterior ear defect, with excellent aesthetic results.

Surgical Site Infection Risk Factor Analysis in Postbariatric Patients Undergoing Body Contouring Surgery: A Nested Case-Control Study.

BACKGROUND: Surgical site infections (SSIs) following body-contouring plastic surgery pose a significant burden on patients and caregivers, possibly leading to undesired surgical outcomes. Surgical site infection incidence following body-contouring plastic surgery ranges from 2% to 7%, but is estimated much higher among postbariatric massive weight loss (MWL) patients. OBJECTIVE: The aim of this study was to evaluate SSI rate, risk and protective factors among postbariatric MWL patients following body-contouring plastic surgery. METHODS: This was a nested case-control study of MWL patients who underwent body-contouring plastic surgery at the Department of Plastic Surgery at Assaf Harofeh Medical Center, between 2007 and 2014. Data were obtained from medical records. Surgical site infection was defined according to the Centers for Disease Control and Prevention criteria. Logistic regression was conducted to assess independent risk factors for SSIs. RESULTS: From a cohort of 172 patients, 86 were included in the study. Surgical site infection rate was 20% (n = 17). Significant SSI risk factors included lifetime maximal weight and lifetime maximal body mass index (P = 0.039 and P = 0.002, respectively), body mass index loss prior to surgery (P = 0.032), estimated blood loss during surgery (P = 0.002), and gynecomastia repair procedure (P = 0.038). Independent SSI-associated factors included thigh lift procedure (odds ratio, 4.66; 95% confidence interval, 1.13-19.28) and preoperative antimicrobial prophylaxis (odds ratio, 0.04; 95% confidence interval, 0.03-0.61). CONCLUSIONS: Although not required by current guidelines for body-contouring plastic surgery, preoperative antimicrobial prophylaxis in our study demonstrated a significant protective effect against SSIs. Further research may reveal its true contribution to SSI prevention in body-contouring plastic surgery.

Preoperative Implant Size Is Strongly Associated With Alternations of Implant Size During Secondary Breast Augmentation.

BACKGROUND: Breast augmentation is one of the most popular cosmetic surgeries performed worldwide. In turn, there has been an increasing number of secondary breast augmentation procedures in recent years. Implant selection at secondary breast augmentation can be a challenge and is affected by a number of factors. The aim of this study was to assess the main factors affecting the decision-making process with regard to implant volume determination prior to implant exchange. METHODS: Women who underwent elective breast implant exchange between 2012 and 2016 were included in this study. Medical records were used to acquire implant and patient data. The patient's desires, as well as medical considerations, were taken into account during the implant selection process. RESULTS: Two hundred forty-five women with an average age of 43 years (range, 21-69 years) were included in the study. The mean time between primary augmentation and implant exchange was 10 ± 5.7 years. Overall, 192 implants (38.9%) were exchanged with larger implants, 84 implants (17%) were exchanged with smaller implants, and 218 implants (44.1%) were exchanged with implants similar to the preoperative size (±25 mL). In patients who received smaller implants, the mean reduction in implant volume was found to be 78.88 mL. Women were more likely to receive a smaller implant during implant exchange if the preoperative implant volume was larger than 367 mL (P = 0.00006). Among patients who received larger implants, no correlation was found between preoperative and postoperative implant size. A positive correlation was found between the implant age and a reduction in implant size (P = 0.036). However, no correlation was found between the patient's age and the decision to reduce or enlarge implant size upon revision. CONCLUSIONS: Almost half of patients receive similarly sized implants during elective implant exchange. Among those who did decide to change their implant size, more than twice as many patients opted for a larger implant as opposed to a smaller one. Relatively large preoperative implant size and longer time since primary augmentation were associated with the selection of smaller implants during exchange. Further studies should be conducted to reinforce these results.

Poly Implants Prosthèse Breast Implants: A Case Series and Review of the Literature.

BACKGROUND: Silicone breast implants from the French manufacturer Poly Implants Prosthèse (PIP) were recalled from the European market after the French regulator has revealed the implants contain non-medical-grade silicone filler. In December 2011, following a large increase in reported rupture rate and a possible cancer risk, the French Ministry of Health recommended consideration of the PIP explantation, regardless of their condition. In 2012, the Israel Ministry of Health recommended to replace the implants only upon suspected implant rupture. OBJECTIVES: The aims of this study were to characterize breast-augmented Israeli patients with PIP implants, compare their outcomes with those of breast-augmented patients with different implant types, and review the current PIP literature. METHODS: Breast-augmented patients who underwent an elective breast implant exchange in Israel between January 2011 and January 2017 were included in the study. Data were collected from electronic and physical medical files. RESULTS: There were 73 breast-augmented female patients with 146 PIP breast implants included in this study. Average implant age was 6.7 ± 2.79 years. Mean implant size was 342.8 ± 52.9 mL. Fourteen women (19 implants [16%]) had a high-grade capsular contracture (Baker grade 3-4). During exchange, 28 implants were found to be ruptured (19.2%). CONCLUSIONS: Less than 10 years following breast augmentation, PIP implants demonstrated higher rupture rate compared with other implants. Our data are comparable to overall available rupture rate. Among patients with definitive rupture diagnosis, an elective implant removal should be recommended. In cases of undamaged implants, plastic surgeons should also seriously consider PIP implant explantation. When the patient does not desire to remove the implant, an annual physical examination and breast ultrasound are recommended, beginning a year after augmentation.

Histopathological Study of Meshed Versus Solid Sheet Acellular Dermal Matrices in a Porcine Model.

BACKGROUND: Acellular dermal matrices (ADMs) are commonly used to support implant-based breast reconstruction. However, there is little comparative data on the incorporation process of different ADMs, and the value of meshing or fenestration versus solid sheet has not been established, although early clinical data suggest seroma rates may be reduced. This was a preclinical assessment of the incorporation process at optimal conditions in a pig model. METHODS: SurgiMend and AlloDerm matrices were implanted in subcutaneous pockets on the backs of 15-week-old female pigs. Half of the samples were meshed 1:2.5; the remainder was grafted as a fenestrated (SurgiMend) or solid sheet (AlloDerm). Tissues were harvested at 3 months. Histological slides were prepared for hematoxylin and eosin staining, and Masson trichrome and immunostaining with anticollagen type I fluorescein isothiocyanate stain. Histological parameters (inflammation, giant cell reaction, neovascularization, fibroplasias, and scar tissue formation) were graded blindly on a scale of 0 (no reaction) to 3 (severe reaction). RESULTS: All explanted ADMs (SurgiMend, n = 23; AlloDerm, n = 20) were firmly incorporated within the host tissue. SurgiMend showed more fibroplasia (P = 0.029) compared with AlloDerm in meshed or solid sheet form. Meshed ADMs showed a trend toward increased inflammation (P = 0.074) and giant cell reaction (P = 0.053) compared with solid sheet/fenestrated ADM. CONCLUSIONS: Meshing ADM may allow cells to populate matrices more rapidly, promoting integration compared with solid sheet ADMs. This study sets the histological basis for further clinical investigations, with the aim of demonstrating lower complication rates (and particularly reduced seroma formation) with meshed ADMs.

Motivational Factors in Women Seeking Augmentation Mammoplasty Across Different Age Groups: A Cross-Sectional Survey.

BACKGROUND: Augmentation mammoplasty is one of the most common esthetic procedures worldwide. A wide range of motivations leads women to undergo this procedure, among them socioeconomic status and age group. The aim of this study was to identify the motivation spectrum for augmentation mammoplasty through different age groups. METHODS: We conducted a cross-sectional prospective survey given to Israeli women seeking augmentation mammoplasty consults in a hospital and private clinic settings, using a 17-item Motivation for Augmentation questionnaire. Three motivation domains were examined: appearance, sexuality and social. Study participants were divided into three age groups: 18-29, 30-39 and over 40 years. RESULTS: A total of 101 women participated in the study. Motivations were rated similar among all age groups. Appearance and sexuality domains were rated significantly higher compared with the social domain throughout all age groups (3.28 ± 0.91 and 3.15 ± 1.03 vs. 1.88 ± 1.16, p < 0.001, respectively). CONCLUSIONS: Motivations in Israeli women seeking breast augmentation do not change with age. The desire to improve one's appearance and sexuality is more prominent than improving social and work status.

Forehead Lift Using Botulinum Toxin.

BACKGROUND: The principle of dynamic muscular activity affecting eyebrow height and shape is well known. We postulate that similarly, dynamics of the fronto-galea-occipital muscles affect forehead height. OBJECTIVES: To present a forehead lift technique using Botulinum toxin injection and evaluate its clinical efficacy and safety. METHODS: Twenty-nine female patients comprised the study group. Forty units of prepared abobutolinumtoxinA (Dysport, 10 U/0.05 mL) were injected into 4 points in the hair-bearing scalp, simulating the points of frontalis origin. The glabella and forehead regions were treated with 50 U each. Standard photographs and measurements were taken before and at 2 weeks following treatment. Forehead height was measured bilaterally drawing a vertical line from mid-pupil to frontal hairline (MPFH) and from medial canthus to frontal hairline (MCFH). We assessed outcome differences in patients with low vs high forehead (cutoff value 5.5 cm forehead height). RESULTS: Mean age was 48 years (range, 29-66 years). Two weeks following treatment, mean frontal height had increased significantly in all measurement points (MCFH right: 4.1 ± 1.8 mm, MCFH left 4.4 ± 1.8 mm, MPFH right 4.4 ± 2.0 mm, MPFH left 4.7 ± 2.3 mm; P <0.001). Low forehead subgroup achieved significantly higher forehead lift compared with high forehead subgroup both in MCFH (6.9% ± 2.0% vs 5.3% ± 2.2%, P = 0.043) and MPFH (8.6% ± 2.5% vs 5.7% ± 2.6%, P = 0.008). No adverse events were documented in any participant. CONCLUSIONS: Botulinum toxin type A injection into frontalis origin can effectively and safely extend forehead height in selected patients. The effect of this technique is greater on patients with low foreheads.

Skin-sparing mastectomy flap ischemia salvage using urgent hyperbaric chamber oxygen therapy: a case report.

Since its introduction in 1991, skin-sparing mastectomy has emerged as an acceptable surgical technique in the management of breast cancer patients, providing optimal oncological safety and efficacy with favorable aesthetic results. Rates of native skin flap ischemia and necrosis after skin-sparing mastectomy are 2%-30% and result in a decreased aesthetic outcome and delay of necessary adjuvant treatment. Hyperbaric oxygen therapy has been advocated for the management of various compromised flaps, and when instituted immediately postoperatively, may prevent progression of ischemia into necrosis. We report the case of a 41-year-old female who developed skin flap ischemia after undergoing skin-sparing mastectomy and was immediately treated with hyperbaric oxygen. The patient received a total of five hyperbaric oxygen therapy sessions, achieving full resolution of the ischemia without any complications. Further research is essential to determine the role of hyperbaric oxygen therapy in managing skin flap ischemia post skin-sparing mastectomy. Until such studies exist, hyperbaric oxygen therapy may be considered a preferred option in the management of native skin flap ischemia after skin-sparing mastectomy.

[The history of plastic surgery in Israel].

The medical institutions in the country have advanced together with the development of the state of Israel. Plastic surgery, which has progressed significantly during the 20th century, has also grown rapidly in the new state. The arrival of Jewish plastic surgeons from all over the world with the knowledge and experience gained in their countries of origin, as well as the need for reconstructive surgical treatment for many combat injured soldiers, also contributed to the development of plastic surgery. This review tells the story of plastic surgery in Israel, since its foundation until nowadays. This article reviews the work of the founders of plastic surgery in Israel, indicating significant milestones in its development, and clinical and scientific contribution to the international plastic surgery profession. Moreover, the article describes the current condition of the field of plastic surgery in Israel and presents the trends and the future challenges facing the next generation of plastic surgery in Israel.

Striae distensae treatment: evaluating laser efficacy and safety.

BACKGROUND: Striae distensae (SD) are common skin lesions that are difficult to treat and affect quality of life. Laser and light are emerging non-invasive therapies that have proven successful in treating SD. Recently, hybrid laser devices offering simultaneous fractional ablative and non-ablative laser treatment have been reported to benefit various skin conditions. OBJECTIVE: To evaluate the improvement of SD treated with a hybrid laser system and to analyze associations with patient characteristics. METHODS: We performed a retrospective study in which 28 adults with SD were treated with a hybrid laser device. Efficacy was evaluated by the assessment of aesthetic improvement by the Global Aesthetic Improvement Scale (GAIS) of 1-10 and by patients' satisfaction using a scale of 0-10 satisfaction scale. Pain and adverse events were monitored. Statistical analysis was used to examine the potential impact of various factors on treatment outcomes. RESULTS: The mean GAIS score was 7.36 ± 1.06 with a positive correlation with patient satisfaction (r = 0.685) and a weak negative correlation with patient age (r = -0.0057). Skin type and body area did not show significant associations with GAIS scores (P > 0.05 for both). No adverse events were observed. CONCLUSION: This study demonstrates the potential of the hybrid laser system as a safe and effective method to achieve satisfactory aesthetic results with minimal downtime, making it a promising treatment approach for SD. Treatment outcomes were independent of patient characteristics, further supporting its widespread use.

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.

The efficacy of combined ultrasound and electric field stimulation therapy in the treatment of venous leg ulcers.

Introduction: Venous leg ulcers are the most common cause of leg ulcers. The aim of this study is to assess the effect of Combined Ultrasound and Electric Field Stimulation therapies (CUSEFS) on wound surface area and pain level in patients with venous leg ulcers, utilizing a novel device (BRH-A2 from BRH Medical, Ltd). Methods: This prospective case series study, conducted by the Department of Plastic Surgery at the Yitzhak Shamir Medical Center, Israel, collected data for subjects treated with CUSEFS with the BRH-A2 device, between April 2018 and September 2019. Measurements of wound area and assessment of pain intensity using a 10-point visual analog score were recorded. At the end of the four-week period, average wound area and pain scores were included for analysis. Results: Ten consecutive patients met the inclusion criteria. During the study period, all patients exhibited a reduction in the wound surface area. The final average wound surface area was reduced by 53.52% following the combined treatment. Eight out of the ten patients (80%) reported a reduction in pain, with an average pain level reduction of 64% throughout eight consecutive treatments. Conclusion: CUSEFS therapies with BRH-A2 technology is a promising treatment for venous leg ulcers. In accordance with our preliminary results, this treatment modality can aid in the reduction of wound surface area as well as reducing the pain suffered by patients from these chronic wounds. Larger multicenter studies are needed to further quantify and qualify the beneficial effect of CUSEFS in venous leg ulcers and other chronic wounds. Lay Summary: Venous leg ulcers (VLUs) are painful wounds occurring between the knee and ankle joint, that fail to heal for a period of at least two weeks and occur in the presence of venous disease. VLUs, are the most common cause of leg ulcers, affecting approximately 5% of the general population over the age of 65. Numerous non-invasive treatment modalities have been attempted for healing chronic wounds and ulceration, however, in some instances surgery, although invasive, is the preferred option. For many years, ultrasound (US) has been used therapeutically to treat chronic ulcers. US produces biophysical effects that are significantly beneficial to the wound healing process. Electrical stimulation therapy is another treatment option which contributes to wound healing by influencing the electrochemical wound process.Combined Modulated Ultrasound and Electric Field Stimulation (CUSEFS) have been shown to improve the healing of chronic wounds. However, research has focused predominantly on objective measures of healing, while less consideration has been given to researching the subjective discomfort and the negative impact that ulceration places on the patient. The aim of this study was to assess objective and subjective factors by measuring the short-term effect of CUSEFS on the surface area of wound and on pain levels in patients with venous leg ulcers (VLUs). Our study findings demonstrate that the combined treatment was effective in initiating wound healing and reducing levels of pain in chronic, stagnant, recalcitrant venous leg ulcers.

Evaluation of a novel anastomotic device in the animal model: A feasibility, safety, and efficacy study.

BACKGROUND: A novel device was designed to assist with microvascular arterial anastomoses. This study compares the safety and efficacy of the anastomosis-assisting device with manual suturing in an ovine model. METHODS: Arteries with a diameter ranging from 2 to 4 mm were transected and anastomosed at four locations. A comparison was done between manual anastomoses and anastomoses performed with a novel anastomotic device in seven sheep. All the device-assisted anastomoses were performed by a single surgeon. At day 45 ± 7, anastomotic sites were dissected to determine patency, and samples were obtained for pathology. RESULTS: Thirteen of 13 (100%) samples from the Vesseal™ group demonstrated patency both on the day the anastomoses were performed and after the 45-day follow-up period. All four additional anastomoses performed using the Vesseal™ were found patent. In the hand-suturing group, six of six (100%) samples demonstrated patency on the day of the anastomoses and five of six (83%) were patent after the follow-up period. No thromboses or adverse events were observed in the anastomoses in either group. No difference in histopathology of the anastomoses was observed between the groups. CONCLUSIONS: The anastomosis-assisting device is a safe and efficacious alternative to hand suturing. The patency rates of device-assisted anastomoses were greater than those of manual suturing and pose no additional risk, as demonstrated by clinical observation, histopathology, and macroscopic evaluation. The Vesseal™ anastomosis-assisting device may be a viable alternative to manual suturing, with an ergonomic and intuitive design, short learning curve, and consistent results.

Silicone breast implant rupture is more prevalent in the dominant limb side: A retrospective cohort study.

BACKGROUND: Breast implant rupture is associated with multiple risk factors such as implant age, manufacturer, and a history of trauma to the breast. However, the exact mechanism of breast implant rupture remains unclear. We hypothesize that repetitive minor mechanical forces on the implant collectively play a significant role in the cascade that eventually leads to its rupture. Therefore, we expect a more significant cumulative effect on the breast implant in the dominant upper limb side. Thus, we aim to ascertain whether laterality in silicone breast implant rupture is associated with the dominant upper limb. METHODS: A retrospective cohort study was performed on patients with silicone breast implants who underwent an elective breast implant removal or exchange. All patients had breast augmentations for cosmetic reasons. We collected data on implant rupture laterality and limb dominance together with known risk factors like patient age, implant age, implant pocket, and implant volume. RESULTS: A total of 154 patients with unilateral implant rupture were included in the study. Among patients with a dominant right limb (n = 133), an ipsilateral rupture was found in 77 patients (58%) (p = 0.036), while in patients with a left dominant limb (n = 21), an ipsilateral rupture was found in 14 patients (67%), (p = 0.036). CONCLUSIONS: The dominant limb was a significant risk factor for ipsilateral breast implant rupture. The prevailing theory that cyclic envelope movement carries an increased rupture risk is reinforced in this study. Extensive prospective studies are needed to clarify risk factors for implant rupture further.
