The Emerging Role of Three-dimensional Technologies in Orthoplastic Surgery.

Three-dimensional (3D) planning and manufacturing technologies have become integral to head and neck reconstruction following tumor resection. These technologies facilitate the prototyping of patient-specific solutions in both digital and physical form. Three-dimensional tumor models and cutting guides help conceptualize and verify the surgical approach, as well as serve as a blueprint for reconstruction. Computer-aided renderings have been shown to add precision to bony contouring to achieve functional and aesthetic goals following tumor resection, such as in mastication, oral competence, speech, and symmetric facial aesthetics. Three-dimensional technologies have also been introduced in orthopedic oncology, making limb-salvage surgery the mainstay of treatment in cases where amputation was historically required. The advent of customized 3D cutting guides and plates allows surgeons to spare surrounding healthy tissue, markedly enhancing postoperative quality of life and significantly reducing associated morbidities. Borrowing from these applications of 3D planning and modeling, our institution has recently implemented these technologies for the reconstructive planning of soft tissue defects following sarcoma resection. Here we present a series of cases that demonstrate the workflow and clinical outcomes associated with the utilization of 3D planning techniques in orthoplastic surgery.

Management of thoracic aortic graft infections with combined omental and bilateral pectoralis major flaps.

BACKGROUND: Aortic vascular graft/endograft infection (VGEI) has historically been managed through graft removal and re-replacement, but new approaches suggest vascularized tissue transfer is an effective adjunctive treatment. We describe our experience with treating thoracic aortic vascular graft infection with combined omental and bilateral pectoralis major myocutaneous (PMM) advancement flaps. METHODS: Data from all patients undergoing combined flap closure by the senior author at a high-acuity cardiac surgery center from 1995-2023 were reviewed. Patients with clinical and radiographic signs of thoracic aortic vascular graft infection were included. RESULTS: Complete data were available for 598 patients with sternal and mediastinal wounds. Combined PMM and omental flaps were mobilized in 11 thoracic aortic vascular graft infection patients. Indications for flap management included culture-positive infection (8/11; 72.7%), dehiscence (5/11; 45.5%), drainage (7/11; 63.6%), and inability to close the sternotomy due to hemodynamic instability (5/11; 45.5%). During chest exploration, 6/11 (54.5%) underwent complete removal of the infected graft, compared to 5/11 (45.5%) who underwent graft-preserving washout and debridement. Immediate flap closure was performed in 6/11 (54.5%). Postoperative complications included dehiscence (2/11; 18.2%), seroma (1/11; 9.1%), hematoma (1/11, 9.1%), abdominal hernia (1/11; 9.1%), and recurrent infection (1/11; 9.1%). One patient (9.1%) died within 30 days of sternal reconstruction from mitral valve failure tachyarrhythmia. None of the patients underwent reoperation for flap-related complications. CONCLUSIONS: Despite significant comorbidities, low postoperative morbidity and mortality indicate that combined omental and pectoralis major flaps are a safe and effective adjunctive treatment to the antimicrobial and surgical management of select thoracic aortic vascular graft infections.

The Lost and Variable Cause: A Systematic Review of Shunt-Related Craniosynostosis Occurrence.

OBJECTIVE: Shunt-related craniosynostosis (SRC) is the premature fusion of cranial sutures possibly due to a loss of tension across dura and suture lines after placement of a shunt for hydrocephalus. As modifications in approaches toward shunting represent a modifiable risk factor, prior literature has investigated the determinants and outcomes. However, the data remain highly variable and are limited by single-institution studies. METHODS: A systematic search of PubMed, Embase, and Web of Science from inception to February 2022 was conducted. Studies were screened by 2 reviewers for eligibility based on predefined inclusion/exclusion criteria. RESULTS: In the 9 included articles, the average follow-up time for the entire cohort ranged from 1.5 to 4.2 years. The pooled incidence of SRC across all 9 studies was 6.5% (140/2142), with an individual range of 0.53% (1/188) to 48.8% (61/125). The average time from shunt placement to SRC diagnosis ranged from 0.25 years to 4.6 years. 61% (65/110) of cases included only one suture, 88% (25/28) of these involved the sagittal suture, and those cases with multiple fusions also had 98% involvement of the sagittal suture (45/46). Overall, 94% (1783/1888) of patients had a fixed shunt placed. CONCLUSIONS: Shunt-related craniosynostosis is likely an underreported complication in the treatment of hydrocephalus. Older age at shunt placement, increased number of shunt revision procedures, and lower valve pressure settings may be risk factors for SRC development. Results also indicate that craniosynostosis can develop months to years after shunting. Future quality studies with standardization of data reporting processes are warranted to investigate this clinical problem.

Making a Statement: Positions of Professional Medical Organizations Towards Gender-Affirming Care.

OBJECTIVE: Despite politically charged media coverage and legislation surrounding gender affirming care (GAC), many organizations have released position statements to provide scientifically backed clinical practice standards, combat misinformation, and inform medicolegal policies. The purpose of this study is to objectively assess the availability and the content of the official position statements of relevant medical professional organizations regarding GAC. SUMMARY BACKGROUND DATA: A list of U.S. medical professional organizations with likely involvement in GAC based on medical or surgical specialties was compiled. METHODS: For included organizations, we evaluated the availability, content, and publication year of positions on GAC through October 2023. When available, formal positions were categorized as supportive or unsupportive. RESULTS: A total of 314 professional medical organizations were screened for our study based on specialty, relevance to GAC, and issuance of patient guidelines or position statements. Inclusion criteria were met by 55 organizations. Most organizations (35, 63.6%) had formal position statements on GAC. Support for GAC was described in 97.1% (n=34). Further, 94.2% (n=33) of available statements explicitly addressed GAC in individuals less than 18 years old and were largely supportive (96.9%, n=32). CONCLUSIONS: This cross-sectional analysis demonstrates that a majority of multidisciplinary professional medical organizations with relevance to GAC have issued formal position statements on the topic. Available positions were overwhelmingly supportive of individualized access to gender-affirming therapies in adult and adolescent populations. However, silence from some organizations continues to represent a modifiable disparity in the provision of GAC.

Catastrophic complications following microvascular free tissue transfer: A 10-year review of NSQIP data.

INTRODUCTION: There is an absence of literature regarding the risks of catastrophic medical outcomes (CMOs) such as stroke, cardiac arrest, and pulmonary embolism in microvascular free tissue transfer. This study aims to determine the CMO and mortality rates, as well as risk factors, associated with microvascular reconstruction of the head and neck, extremity, and breast. METHODS: This study uses data from the American College of Surgeons National Surgical Quality Improvement Program. Cases of microvascular free tissue transfer from 2012 to 2021 were analyzed to assess the 30-day rates of CMOs, including death, as well as associated risk factors. RESULTS: Of the 22,839 included patients, 785 (3.44%) experienced 1043 CMOs, including 99 (0.43%) deaths. Pulmonary complications of prolonged respiratory failure and pulmonary embolism were the most common. Independent risk factors included age, male sex, underweight status, longer operation times, American Society of Anesthesiologists (ASA) class of III or above, wound classification other than clean, and underlying conditions such as diabetes, hypertension, chronic obstructive pulmonary disorder, dyspnea, metastatic cancer, and ventilator dependence. CMOs were associated with an average 10-day delay in hospital discharge. Multivariate regression analysis revealed that head and neck reconstructions were associated with increased risk of CMO (OR 4.96; p < 0.0001). CONCLUSION: This is the largest study to examine CMOs following microvascular free tissue transfer. Compared to previous literature spanning the period between 2006 and 2011, we observed a decreased rate of CMOs but a slight increase in 30-day mortality. Our data provide updated and comprehensive criteria for risk stratification and patient counseling. The modifiable risk factors reported in our study should be considered in elective, non-urgent cases of microvascular reconstruction.

Flap management following orthotopic heart transplantation: A single institution's review of 66 sternal wound complications.

BACKGROUND: Sternotomy wound complications are more frequent after orthotopic heart transplantation (OHT) compared to other cardiac surgeries, primarily due to additional risk factors, including immunosuppression. Flap closure often becomes necessary for definitive treatment, although there is a scarcity of data on the outcomes of sternal wound reconstruction in this specific population. METHODS: A retrospective analysis was conducted on 604 sternal wound reconstructions performed by a single surgeon between 1996 and 2023. Inclusion criteria comprised patients who underwent OHT as their primary cardiac procedure. Surgical interventions involved sternal hardware removal, debridement, and muscle flap closure. RESULTS: The study included 66 patients, with culture-positive wound infection being the most common indication for reconstruction (51.5%). The median duration between transplantation and sternal wound reconstruction was 25 days. Bilateral pectoralis major myocutaneous advancement flaps (n = 63), rectus abdominis flaps (n = 2), or pectoralis major turnover flaps (n = 1) were used. Intraoperative wound cultures revealed positivity in 48 patients (72.7%), with Staphylococcus epidermidis being the most frequently cultured organism (25.0%). The overall complication rate was 31.8%, and two patient deaths were related to sternal wounds, resulting from multiorgan failure following septic shock. The majority of the patients reported excellent long-term functional and esthetic outcomes. CONCLUSIONS: Sternal wounds following OHT pose a significant morbidity risk. Our strategy focuses on immediate and aggressive antibiotic therapy, thorough debridement, and definitive closure with bilateral pectoralis myocutaneous advancement flaps. This approach has demonstrated complication and mortality rates comparable to the general cardiac surgery population, as well as excellent functional and esthetic results.

Trends in orthoplastic operative exposure for plastic surgery residents in the United States.

BACKGROUND: Recent trials have demonstrated clinical benefits to a combined orthoplastic approach for complex reconstructive surgery of the hand, upper and lower extremity. PURPOSE: We sought to assess recent trends in exposure to orthoplastic-type procedures among plastic surgery residents training in the United States. METHODS: Independent plastic surgery residents' case logs were extracted from the Accreditation Council for Graduate Medical Education (2011-2022). Select reconstructive procedure were taken as proxies for orthoplastic-type cases and analyzed by descriptive statistical analysis. RESULTS: The average number of orthoplastic-type cases completed per resident per year increased from 168.2 to 189.2 (12.5% increase) between 2011-2022. The greatest increase was in exposure to peripheral nerve injury repair of the hand and upper extremity (22.6 to 39.1, 73% increase). As a proportion of total procedures during the study period, orthoplastic-type procedures remained relatively unchanged (range 9.5-10.4%). CONCLUSIONS: Our findings suggest that plastic surgery residents may be increasingly well-prepared to contribute to orthoplastic care during and following their training. The steady proportion of cases that orthoplastic-type procedures represented over the study period suggests the increase in relevant orthoplastic case volume may be incidental and secondary to an overall rise among all procedures. Given evidence of the benefits of an orthoplastic approach, we recommend consideration of explicit benchmarks for orthoplastic training among plastic surgery residents.

A Systematic Review of the Orthoplastic Approach in Adult Lower Extremity Soft Tissue Sarcoma Flap Reconstruction.

BACKGROUND: The orthoplastic approach to patient care has changed the way patients with a wide variety of lower extremity pathology are treated. Through a systematic review, we aim to analyze outcomes in adult patients with lower extremity soft tissue sarcomas who undergo an orthoplastic flap management approach to their care. METHODS: A systematic review of adult lower extremity soft tissue sarcoma excision with plastic surgery flap reconstruction was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines searching the Pubmed, Embase, and Web of Science databases from inception to April 2023. RESULTS: After removal of duplicates, title and abstract screening, and full-text review, 26 articles were accepted for inclusion. The total mean follow-up duration was 32.0 ± 24.3 months. Reconstruction used microvascular free flaps in 65.5% (487/743), while 34.5% (256/743) were local flaps. 85.8% (307/358) of patients ambulated postoperatively. Revision surgery was required in 21% of patients during their respective follow-up periods. The limb salvage rate was 93.4% (958/1,026). Among pooled surgical outcomes, 22.2% (225/1,012) of patients experienced a perioperative complication. DISCUSSION: Our study demonstrates that although complication rates in lower extremity soft tissue sarcoma reconstruction may be further optimized, a multidisciplinary flap reconstructive approach provides high rates of limb salvage and functional postoperative ambulation.

Masculinizing Chest Reconstruction in Adolescents and Young Adults: An Analysis of National Surgical Quality Improvement Program Data.

BACKGROUND: Masculinizing chest reconstruction (MCR) has been shown to improve quality of life and gender dysphoria in transmasculine adult patients. As nationwide access to gender-affirming care expands, more adolescents are seeking MCR. However, there is a paucity of literature examining patient characteristics, safety, and disparities among this population. METHODS: Cases of MCR were selected from the pediatric and adult American College of Surgeons and National Surgical Quality Improvement Program. Adolescent (18 years and older) and young adult (aged 19-25 years) transgender patients were analyzed for differences in demographics, comorbidities, surgical characteristics, and postoperative complications. RESULTS: A total of 1287 cases were identified, with an adolescent cohort of 189 patients. The proportion of White patients to other races was greater among adolescents than young adults (91.2% vs 82.4%, P = 0.007). Of adolescents and young adults, 6.0% and 11.1% identified as Hispanic/Latino, respectively (P = 0.059). Rates of all-cause postoperative complications were similar between adolescents (4.2%) and young adults (4.1%). Multivariate binary logistic regression showed that Black or African American patients experienced more all-cause postoperative complications than other races after controlling for American Society of Anesthesiologists classification, age group, and body mass index (odds ratio, 2.8; 95% confidence interval, 1.3-5.9; P = 0.008). CONCLUSIONS: Masculinizing chest reconstruction is equally safe for transmasculine adolescent and young adult patients. However, our data point to racial disparities in access to care and postoperative outcomes. An intersectional approach is needed to better understand the unique health care needs and barriers to care of minority transgender youth.

The impact of a shadowing program on medical students' interest in plastic surgery.

Given the lack of formal education on plastic surgery services during the preclinical years of medical school, many medical students commonly misunderstand the breadth and depth of the field. Shadowing is highly impactful in shaping students' desire to pursue surgery, but the impact of plastic surgery shadowing remains unexplored. The study design utilized an anonymous web-based survey containing questions surrounding prior interest in surgery, race, gender, medical school progress, and clinical versus OR shadowing. All medical students who participated in an ongoing, voluntary plastic surgery shadowing program over a two-year period were invited to complete the survey. Of the 54 students who shadowed during the study period, 43 (79.6%) returned the survey. Students reported an overall greater impact of OR shadowing than clinic shadowing on their interest in plastic surgery, approaching significance (p = 0.0527). On simple and multivariate regression, the number of times a student shadowed in the OR was the only statistically significant predictor of students' interest in plastic surgery (p = 0.0003). In general, the majority of students reported that their shadowing experience "significantly increased" (24.2%) or "somewhat increased" (45.5%) their interest in pursuing a career in plastic surgery. The impact of shadowing, particularly in the operating room, on students' interest in plastic surgery demonstrates the value of structured shadowing programs. Additionally, given the particularly influential effect of shadowing in the operating room, our results indicate that efforts may benefit most from facilitating student exposure to the hands-on aspects of the field.

National Legislative Favorability and Insurance Coverage for Adult and Adolescent Gender-Affirming Surgery.

BACKGROUND: Despite established medical necessity, laws prohibiting coverage discrimination, and increasing numbers of transgender and gender diverse patients seeking gender-affirming surgeries (GAS), cost and restrictive insurance policies continue to be the most common barriers. As recent legislation places further restrictions on GAS, this study aims to provide an updated review of insurance policies and assess the relationship between legislative favorability and coverage. METHODS: Insurance policies of groups representing 80% market coverage in each state were collected for gender-affirming chest, genital and facial surgery. Policies were categorized based on previously published methodologies: never-covered (N), case-by-case (CC), and preauthorization (PA). The relationship between established scores of legislative favorability and policy coverage in each state was analyzed and compared across regions. RESULTS: Of the 316 analyzed policies, coverage was preauthorized most often for genital (94.0%), masculinizing top (93%), feminizing top (74%), and facial reconstruction (24%), respectively. Higher legislative scores in the Northeast and West, as well as individual states were predictive of increased genital, facial, and all forms of adolescent GAS, but were not correlated to chest GAS. CONCLUSION: Compared to previous studies, our findings suggest that there is a growing acceptance of GAS as medically necessary. However, the correlation between legislative scores and genital, face, and adolescent GAS coverage may suggest increased reliance on sociopolitical factors for access in the absence of comprehensive medical guidelines, which are more established for chest reconstruction. Significantly higher coverage of masculinizing versus feminizing chest surgery suggests additional burden of proof for GAS with a cosmetic overlap.

Concordance of National Insurance Criteria with WPATH Standards of Care for Gender-Affirming Surgery.

BACKGROUND: Given that gender-affirming surgery (GAS) is considered medically necessary for transgender and gender diverse (TGD) individuals who desire it, the aim of this study is to assess the concordance of insurance criteria for GAS with the most recent World Professional Association for Transgender Health (WPATH) Standards of Care Version 8 (SOC-8). METHODS: Insurance policies for coverage of gender-affirming genital ("bottom surgery"), chest ("top surgery"), and facial reconstruction from companies representing 80% of the market coverage in each state were evaluated. Policies were classified into three categories: no-coverage (NC), case-by-case (CC), and preauthorization (PA). Among PA policies, criteria for coverage of specific surgeries were analyzed for adherence to WPATH SOC-8. RESULTS: Bottom surgery policies were most concordant for age and gender dysphoria criteria, and transmasculine top surgery policies were most concordant for hormone therapy, continuous living in a congruent gender role, and referral criteria. transfeminine top surgery criteria were more restrictive than transmasculine criteria. The most discordant criteria was for hormone therapy, being required for at least 12 months prior to surgery in the majority of surveyed policies. Many specific procedures and treatments were excluded, especially facial GAS with cosmetic overlap. Additionally, reversal and revisionary surgeries were covered in less than 25% of policies. CONCLUSION: Compared to previous literature, insurance coverage and criteria alignment are becoming more concordant with medical guidelines. However, significant barriers to care are still present for GAS.

Complications in craniosynostosis surgery in patients with rickets: illustrative case and systematic review of literature.

BACKGROUND: Craniosynostosis (CSS) is the premature fusion of calvarial sutures associated with identified genetic mutations or secondary to alterations in intracranial pressure, brain, or bone growth patterns. Of the metabolic etiologies implicated in CSS, X-linked hypophosphatemic rickets (XLHR) is the most common, with dysfunctional bone mineralization leading to progressive hyperostosis and delayed synostosis. There is a paucity of literature discussing the unique surgical considerations for XLHR-related CSS. OBSERVATIONS: A 26-month-old male with XLHR-related sagittal CSS underwent cranial vault remodeling (CVR). Surgery was complicated by the presence of diploic hypertrophy with significant intraoperative estimated blood loss (EBL). EBL greatly exceeded reference ranges for CVR in all-cause CSS. As a result, the surgical goals were modified and the complete planned procedure aborted. Subsequent review of preoperative imaging revealed multiple fine vascular lacunae within the bone. A systematic literature review was conducted to identify reported complications relating to surgical intervention for rickets-associated CSS. LESSONS: Future considerations for patients with XLHR-related CSS should emphasize awareness of metabolic risk factors with associated complications, and the need for selection of approach and operative management techniques to avoid EBL. Further research is required to elucidate underlying mechanisms and determine whether the encountered phenomenon is characteristic across this patient population and potentially minimized by preoperative medical therapy.
