BACKGROUND: In addition to its intended purpose of perforator mapping, computed tomography angiography can also identify incidental findings that may require further evaluation. In this multi-institutional study, the authors evaluated the frequency of incidental findings and their significance and effects on treatment course and aimed to identify risk factors for detecting such findings. METHODS: A retrospective review of patients who underwent perforator mapping with computed tomography angiography was performed over a 5-year period from three academic institutions. Relevant sociodemographic and clinicopathologic information, computed tomography angiography reports, follow-up visits, and treatment outcomes were reviewed. Univariate and multivariate analyses were performed to assess the relationship between risk factors and incidental findings. RESULTS: From January of 2015 to July of 2020, a total of 656 patients were identified who met inclusion criteria. Overall, 342 incidental findings were found, 76 of which required additional imaging or consultation. Ultimately, 10 patients (1.5 percent) had findings that altered reconstructive management, including five patients (0.8 percent) having severe disease that resulted in the cancellation of their reconstruction. Advanced age and immediate reconstruction timing were independent risk factors for incidental findings. CONCLUSIONS: Incidental findings are commonly identified on preoperative computed tomography angiography for deep inferior epigastric perforator flap breast reconstruction. Suspicious findings should be investigated thoroughly because they can alter the reconstructive course. Understanding of high-risk groups for incidental findings can further advance patient education during initial consultation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Tighter abdominal wall reconstruction may increase intra-abdominal pressure, which can decrease lower extremity venous return. Decreased venous return through the inferior vena cava has been demonstrated to increase risk of deep vein thrombosis.Tighter abdominal wall plication during cosmetic abdominoplasty compared with functional panniculectomy may increase these risks. The purpose of this study was to determine whether cosmetic abdominoplasty increases risk for thromboembolic events compared with functional panniculectomy.Retrospective cohort study was conducted using the National Surgical Quality Improvement Program database for excision of excessive subcutaneous infraumbilical skin and soft tissue at participating hospitals between 2015 and 2019. Procedures performed for cosmetic abdominoplasty versus functional panniculectomy were compared for occurrences of postoperative pulmonary embolism (PE).During the study interval, 11,137 patients underwent excision of excessive infraumbilical abdominal skin, including 57.4% (n = 6397) patients undergoing functional panniculectomy and 42.6% (n = 4740) patients undergoing cosmetic abdominoplasty. Patients undergoing functional panniculectomy were significantly more likely to have comorbidities than those undergoing cosmetic abdominoplasty ( P0.001). The risk for postoperative PE was independently associated with cosmetic abdominoplasty ( P0.001), elevated body mass index ( P = 0.001), preoperative recent weight loss ( P = 0.006), and concurrent hernia repair ( P = 0.049). Most PE events occurred outpatient after discharge (87.2%), and the average postoperative time from surgery until PE was 10.5 ± 6.7 days.Cosmetic abdominoplasty has greater than 4 times the risk of postoperative PE than functional panniculectomy. Risk of PE is further increased by concurrent hernia repair, elevated body mass index, and rapid weight loss in the immediate preoperative period. It may be advisable to caution patients to delay abdominal excisional body contouring procedures until their weight has plateaued.

Background The location of tissue expanders in implant-based breast reconstruction remains controversial, due to variation in surgical techniques and devices. Objectives This study aims to provide a comprehensive assessment of early and late complication rates between prepectoral and subpectoral placement of tissue expanders. Methods A retrospective cohort study was conducted of all adult female patients who had two-staged implant-based breast reconstruction from 2013 to 2019 in our institution. Early complication was defined as complications that occurred within 30 days after surgery. Time-to-event analyses were performed and Cox proportional hazard models were used to adjust for confounders. Results 854 patients were included with 76% of patients underwent a subpectoral tissue expander placement. After the first stage procedure, the early complication rate was 34%, and the late complication rate was 36.4%. After the second stage procedure, the early complication rate was 16.3%, and the late complication rate was 16.1%. Location of the tissue expander did not predict either overall early or late complication rates, regardless of the stages of reconstruction, after adjusting for confounders. Tissue expanders placed in prepectoral plane were associated with a higher hazard ratio (HR) for developing early and late infection after the first stage of reconstruction (HR 2.1, HR 2.4, respectively) as well as late infection after the second stage of reconstruction (HR 5.3, all p Conclusions Location of tissue expanders did not predict risk of complication. However, the prepectoral group was associated with an increased risk of developing infection.

Background Section 1557 of the Affordable Care Act, introduced in 2016, increased access to gender-affirming surgeries for transgender and gender diverse individuals. Masculinizing chest reconstruction (e.g., mastectomy) and feminizing chest reconstruction (e.g., augmentation mammaplasty), often outpatient procedures, are the most frequently performed gender-affirming surgeries. However, there is a paucity of information about the demographics of patients who undergo gender-affirming chest reconstruction. Objectives The authors sought to investigate the incidence, demographics, and spending for ambulatory gender-affirming chest reconstruction utilizing nationally representative data from 2016 to 2019. Methods Employing the Nationwide Ambulatory Surgery Sample, the authors identified patients with an International Classification of Diseases diagnosis code of gender dysphoria who underwent chest reconstruction between 2016 and 2019. Demographic and clinical characteristics were recorded for each encounter. Results A weighted estimate of 21,293 encounters for chest reconstruction were included (17,480 [82.1%] masculinizing and 3813 [27.9%] feminizing). Between 2016 and 2019, the number of chest surgeries per 100,000 encounters increased by 143.2% from 27.3 to 66.4 (P Conclusions Gender-affirming chest reconstructions are on the rise, and surgeons must understand the background and needs of transgender and gender diverse patients who require and choose to undergo surgical transitions.

Burn injury remains a serious cause of morbidity and mortality worldwide. Severity of burns is determined by the percentage of burned area compared to the body surface area, age of patient, and by the depth of skin and soft tissue involvement; these factors determine management as well as prospective outcomes. The pathophysiology of partial- to full-thickness burn conversion remains poorly understood and is associated with a worse overall prognosis. Recent studies have demonstrated that an altered inflammatory response may play a significant role in this conversion and therefore a reduction in early inflammation is crucial to ultimately decreasing burn severity and morbidity. We hypothesize that the application of a microcapillary gelatin-alginate hydrogel loaded with anti-TNF-α (infliximab) monoclonal antibodies to a partial-thickness burn will reduce inflammation within partially burned skin and prevent further progression to a full-thickness burn.Assembly of the microfluidic hydrogels is achieved by embedding microfibers within a hydrogel scaffold composed of a gelatin-alginate blend, which is then soaked in a solution containing anti-TNF-α antibodies for drug loading. 12 young (2-4 months) and 12 old (16 months) mice were given partial thickness burns. The treatment cohort received the anti-TNF-α infused hydrogel with an occlusive dressing and the control cohort only received an occlusive dressing. Mice were euthanized at post-burn day 3 and skin samples were taken. Burn depth was evaluated using Vimentin immunostaining.All mice in the treatment cohort demonstrated decreased conversion of burn from partial to full thickness injury (old = p0.01, young = p0.001) as compared to the control group. Old mice had greater depth of burn than young mice (p0.001). There were greater eosinophils in the treatment cohort for both young and old mice, but it did not reach statistical significance.The application of a novel microcapillary gelatin-alginate hydrogel infused with anti-TNF-α antibody to partial thickness burns in mice showed reduction in partial to full thickness burn secondary progression as compared to controls using this murine model; this promising finding might help decrease the high morbidity and mortality associated with burn injuries.

Background Although there are many indications for periprosthetic breast capsulectomy, heightened public attention surrounding breast implant illness has resulted in increased rates of capsulectomy. Objectives This study aimed to identify the incidence of major complications and risk factors associated with capsulectomy. Methods From an examination of a prospectively enrolled cosmetic surgery insurance database, CosmetAssure (Birmingham, AL), patients undergoing capsulectomy between January 2, 2017 and July 31, 2019 were identified. Outcomes measured included the occurrence of and risk factors for major complication(s) necessitating an emergency department visit, hospitalization, or reoperation within 45 postoperative days. Results Among 76,128 patients evaluated, 3048 (4.0%) underwent capsulectomy. There was a significant increase in number of capsulectomies following January 6, 2019 (2.7/day vs 5.2/day, P Conclusions A growing number of capsulectomies are being performed. The most common major complication is hematoma. Patients undergoing capsulectomy experience a higher complication rate than those undergoing breast implant removal or replacement without capsulectomy. Patients should be counseled regarding the potential for major complications. Level of Evidence: 2

Microvascular free tissue transfer is an increasingly popular modality for autologous tissue breast reconstruction. However, flap failure remains an ominous risk that continues to plague surgeons and patients even in the setting of meticulous surgical technique and monitoring. Venous and arterial thromboses are the leading causes of free flap failure. The purpose of this study was to determine whether thrombocytosis is associated with breast free flap failure.A retrospective study was conducted of breast reconstruction with free flaps in North America between 2015 and 2020 using the National Surgical Quality Improvement Program database. Patient comorbidities and preoperative laboratory tests were used to determine risk factors for free flap failure.During the study interval, 7522 female patients underwent breast reconstruction with free flaps, and flap failure occurred in 2.7% patients (n = 203). In multivariate regression analysis, breast free flap failure was significantly higher in patients smoking cigarettes within the past year (P = 0.030; AOR, 1.7) and dyspnea on moderate exertion or at rest (P = 0.025; AOR, 2.6). Furthermore, each 50 K/mcL elevation in platelet count was independently associated with an increased odds of flap failure (P0.001; AOR, 1.2). Patients experienced significantly higher rates of flap failure with platelet counts greater than 250 K/mcL (P = 0.004), which remained significant through progressively increasing thresholds up to 450 K/mcL.Platelet count greater than 250 K/mcL is associated with progressively increasing risk of free flap failure in breast reconstruction. Future studies of personalized patient anticoagulation protocols based on hemostatic metrics may improve free flap survival after autologous tissue breast reconstruction.

Background Post-mastectomy pocket irrigation solution choice is debated and primarily surgeon dependent. We compare triple antibiotic solution (TAS) with 0.05% chlorhexidine gluconate (CHG). Objectives The purpose of this study was to determine surgical site infection (SSI) rates after utilizing TAS vs CHG for breast pocket irrigation in immediate tissue expander (TE) breast reconstruction. Methods A prospective, blinded, randomized controlled trial was performed in patients (18-81 years old) who underwent bilateral mastectomy with TE reconstruction. In each patient, 1 mastectomy pocket was randomized to TAS and the other to CHG. Both the TE and the pocket were irrigated in the respective solution. The primary outcome was the incidence of SSI. Secondary outcomes were rates of mastectomy flap necrosis, hematoma, and seroma. Results A total of 88 patients who underwent bilateral immediate breast reconstruction were enrolled. Demographic and operative characteristics were equivalent because each patient served as their own control. Between the TAS and CHG groups, the incidence of SSI did not differ (5 [4.5%] vs 7 [8.0%], P = 0.35), including minor infections (2 [2.3%] vs 1 [1.1%], P = 0.56), major infections (2 [2.3%] vs 6 [6.8%], P = 0.15), and those resulting in explantation (2 [2.3%] vs 5 [4.5%], P = 0.25). Necrosis, hematoma, or seroma formation also did not differ. No patients who developed SSI received radiation. Conclusions This study does not demonstrate a statistically significant difference in SSI between TAS and CHG irrigation, though TAS approached statistical significance for lower rates of infectious complications.

BACKGROUND Neuromata developed after major extremity amputation can cause pain, limit the use of prosthetics, and negatively affect the quality of life. The frequency of postamputation neuroma varies widely. The objective of this study was to determine the incidence of patients who developed symptomatic neuromata after lower-limb amputation through a systematic review and meta-analysis. METHODS A systematic review of the literature was performed on 4 major databases. Studies that reported the incidence of symptomatic neuroma in lower-limb amputees were included. A meta-analysis was performed to calculate the pooled incidence of neuromata. RESULTS Thirteen studies consisting of 1329 patients were included in this meta-analysis. The reported incidence of patients who developed symptomatic neuromata ranged between 4% and 49%. The median duration of follow-up was 8.6 years (interquartile range, 2.0-17.4 years). The pooled percentage (95% confidence interval [CI]) of lower-limb amputees who developed symptomatic neuromata was 19% (12%-29%). In studies with a duration of follow-up at least 3 years, the pooled percentage (95% CI) of lower-limb amputees who developed symptomatic neuromata was 30% (22%-40%). In studies with a follow-up period of fewer than 3 years, the pooled percentage (95% CI) of neuroma incidence was 3% (2%-6%). CONCLUSIONS In summary, the overall incidence of patients who developed symptomatic neuromata was 19% or approximately 1 in 5 lower-limb amputees. Symptomatic neuromata are more commonly diagnosed when the follow-up period is longer than 3 years. These findings suggest that neuroma after amputation might be underestimated in studies with a short duration of follow-up.

American Board of Plastic Surgery (ABPS) diplomates complete training in aesthetic surgery through an Accreditation Council of Graduate Medical Education-accredited program. American Board of Cosmetic Surgery (ABCS) diplomates complete residency training in a "related" specialty, some historically nonsurgical, followed by an American Association of Cosmetic Surgery fellowship. Unlike the ABPS, the ABCS is not recognized by the American Board of Medical Specialties as an equivalent certifying board. This study evaluated differences in the rates of punitive action against diplomates of the ABPS and the ABCS.Diplomates were accessed from their respective society's websites. Punitive action data were obtained by search of publicly available state medical board databases. A comparative analysis was performed between ABPS and ABCS.One thousand two hundred eight physicians were identified for comparative analysis. Two hundred sixty-six (22 percent) were members of the American Society of Plastic Surgeons, and 549 (49 percent) were members of The Aesthetic Society. ABCS diplomates had significantly higher rates of disciplinary administrative action by their respective state medical boards [ n = 31 (9.0 percent)] when compared with ABPS members [The Aesthetic Society, n = 26 (4.4 percent); ABPS, n = 8 (3.1 percent); p = 0.003], with a higher proportion of repeat offenders. In addition, ABCS diplomates had more public letters of reprimand [ABCS, n = 12 (3.5 percent); The Aesthetic Society, n = 6 (1.2 percent); and ABPS, n = 2 (0.8 percent); p = 0.015].ABCS diplomates have significantly higher rates of punitive actions than ABPS diplomates. Although the reasons for this discrepancy warrant further investigation, punitive data should be transparently and publicly available to aid patients in informed decision-making.

Aesthetic surgery patients commonly use online resources to select a surgeon. The American Board of Plastic Surgery is the American Board of Medical Specialties member board that certifies plastic surgeons. The American Board of Cosmetic Surgery (ABCS) provides aesthetic surgery credentials through a non-American Board of Medical Specialties-recognized process. This study examines use of the phrases "plastic surgery" and "plastic surgeon" by ABCS-certified surgeons when advertising online.Diplomates of the ABCS were identified from the ABCS Web site. Professional Web sites, Facebook business pages, and Instagram profiles were located by online search. Use of the descriptor "plastic" and ABCS board certification on practice Web sites, Facebook business page categorization, and plastic surgery-related hashtag use on Instagram were recorded.A total of 298 non-American Board of Plastic Surgery-certified ABCS diplomates were included. One hundred eighty-nine (69.5%) categorized their Facebook business page as "plastic surgeon." Within Instagram posts, 123 (57.2%) used #plasticsurgeon, and 172 (80.0%) used #plasticsurgery. On professional Web sites, 90 (30.4%) identified themselves as a "plastic surgeon," 123 (41.6%) characterized their practice as "plastic surgery," and 196 (68.5%) used their ABCS credential to identify as a "board-certified" cosmetic surgeon.Diplomates of the ABCS frequently use "plastic surgeon" and "plastic surgery" in online advertisements despite a lack of accredited plastic surgery training or board certification. Furthermore, most ABCS diplomates use their ABCS credentials to market themselves as "board-certified" cosmetic surgeons, potentially violating American Medical Association-supported truth in advertising laws in some states and increasing public confusion regarding different board certifications.

In the wake of the recent coronavirus disease of 2019 public health emergency, care delivery by means of telemedicine using audiovisual virtual platforms has become an important tool for patient communication. There are many logistic, medicolegal, and practical aspects of telemedicine that should be considered by the practicing plastic surgeon. Successful virtual patient interactions require an understanding of medical licensure requirements to perform telemedicine visits in a certain region. In addition, it is imperative to be familiar with specific liability and malpractice concerns, in addition to Health Insurance Portability and Accountability Act regulations before conducting electronic visits. During consultations, providers should be aware of proper physician conduct and the potential role of chaperones. Furthermore, appropriate visit documentation, in addition to telemedicine billing and coding, has to be ensured. Lastly, plastic surgeons should adhere to the rules of controlled substance prescription by means of telemedicine platforms. This article describes these salient topics surrounding telemedicine visits that are faced by plastic surgeons and discusses strategies to optimize and ensure safe use of virtual platforms.
