RESUMO

BACKGROUND: Awareness of Medicare reimbursement is important for gender-affirming surgeons who treat transgender patients with Medicare. In 2014, Medicare began to provide coverage for medically necessary transition-related surgery. The purpose of this study was to analyze trends in Medicare reimbursement rates for gender-affirming surgery procedures from 2014 to 2022. METHODS: The Medicare Physician Fee Schedule Look-Up Tool provided by the Centers for Medicare and Medicaid Services was used, and the Current Procedural Terminology codes for 43 gender-affirming surgery services were obtained. Monetary units, conversion factors, relative value units (RVUs) for work, facility, and malpractice costs for 30 transmasculine and 13 transfeminine procedures were analyzed. Descriptive statistics were performed to account for inflation and to determine the relative differences between 2014 and 2022. RESULTS: For all gender-affirming surgery procedures covered by Medicare, the average relative difference of monetary units decreased by 2.99% between 2014 and 2022. On average, there was a 3.97% decrease of work-based RVU charges for transmasculine procedures and a 1.73% decrease of work-based RVU charges for transfeminine procedures. After adjusting for inflation, the average relative difference of monetary units for all gender-affirming surgery procedures decreased by 23.42% between 2014 and 2022. CONCLUSIONS: Reimbursement rates for gender-affirming surgery procedures covered under Medicare have decreased over the observed period, and trends in reimbursement rates have not kept up with consumer price index inflation. Gender-affirming surgeons should be conscious of these changes in reimbursement rates and advocate for fairer compensation to promote medical care among an underserved population.

RESUMO

OBJECTIVE: To describe phalloplasty subunits and determine the preferred crowdsourced esthetics. Esthetic ideals are often used to guide reconstruction, and there has been an increase in the number of gender-affirming surgeries and reconstructive phalloplasties performed. However, there is a paucity of literature describing ideal phalloplasty esthetics. METHODS: Phallus esthetic subunits were defined, and a split testing-based survey was used. Subjects were solicited via Craigslist, Amazon Mechanical Turk, and Reddit and distributed among health care co-workers. Computer-generated images with variable ratios of glans, corona, and shaft were provided and respondents were asked to select the most esthetically pleasing photo. Demographic information was gathered. Univariate and multivariate regression were performed. RESULTS: A total of 1029 people responded to the survey request and 909 people (88.3%) completed the entire survey. There were 440 respondents who self-identified as male, 334 female, 92 transgender male, and 25 transgender female. The health care field was the profession for 55.4%. Health care providers had 65.3% higher odds of preferring the longer shaft length-to-width ratio, 30.3% less odds of preferring a bilateral taper of the glans, and 48.4% less odds of preferring an angulated shaft compared to non-health care providers (P = .006, P = .021, P <.001, respectively). When compared to males, transgender females were more than 13 times likely to prefer an angulated glans corona junction (P = .008). CONCLUSION: The ideal phallic esthetic varies by individual, and there were statistically significant preferences across age, education, health care status, gender, and sexual orientation. This study can serve as a guide on phalloplasties for patients and gender-affirming surgeons.

RESUMO

BACKGROUNDThe loss of insulin-like growth factor 1 (IGF-1) expression in senescent dermal fibroblasts during aging is associated with an increased risk of nonmelanoma skin cancer (NMSC). We tested how IGF-1 signaling can influence photocarcinogenesis during chronic UVB exposure to determine if fractionated laser resurfacing (FLR) of aged skin, which upregulates dermal IGF-1 levels, can prevent the occurrence of actinic keratosis (AK) and NMSC.METHODSA human skin/immunodeficient mouse xenografting model was used to test the effects of a small molecule inhibitor of the IGF-1 receptor on chronic UVB radiation. Subsequently, the durability of FLR treatment was tested on a cohort of human participants aged 65 years and older. Finally, 48 individuals aged 60 years and older with considerable actinic damage were enrolled in a prospective randomized clinical trial in which they underwent a single unilateral FLR treatment of one lower arm. Numbers of AKs/NMSCs were recorded on both extremities for up to 36 months in blinded fashion.RESULTSXenografting studies revealed that chronic UVB treatment with a topical IGF-1R inhibitor resulted in a procarcinogenic response. A single FLR treatment was durable in restoring appropriate UVB response in geriatric skin for at least 2 years. FLR resulted in sustained reduction in numbers of AKs and decreased numbers of NMSCs in the treated arm (2 NMSCs) versus the untreated arm (24 NMSCs).CONCLUSIONThe elimination of senescent fibroblasts via FLR reduced the procarcinogenic UVB response of aged skin. Thus, wounding therapies are a potentially effective prophylaxis for managing high-risk populations.TRIAL REGISTRATIONClinicalTrials.gov (NCT03906253).FUNDINGNational Institutes of Health, Veterans Administration.

RESUMO

SUMMARY: A multi-disciplinary work group involving stakeholders from various backgrounds and societies was convened to develop guidelines for the management of reconstruction after skin cancer resection. The goal was to identify areas of common ground and provide evidence-based recommendations to improve patient care. Given the heterogeneity of reconstructive techniques and clinical scenarios, investigation centered around common elements in the process. In some cases, a distinction was made between treatment options in the office-based setting as opposed to those in the facility setting. A systematic literature review was performed, and an established appraisal process was used to rate the quality of relevant scientific research (Grading of Recommendations Assessment, Development, and Evaluation methodology). Final recommendations are related to concepts concerning the timing of reconstruction, management of anticoagulation, use of antibiotics, methods of pain control, and follow-up assessment. At times, there was insufficient evidence to make high-level recommendations. The literature analysis highlights the need for additional methodologically robust studies in this area, to help guide clinical practice.

RESUMO

BACKGROUND: Recent studies support the prophylactic use of tranexamic acid during craniosynostosis surgery to reduce blood loss. The study aims to assess national trends and outcomes of tranexamic acid administration. METHODS: The Pediatric Health Information System database was used to identify patients who underwent craniosynostosis surgery over a 9-year period (2010 to 2018). Search criteria included patients younger than 2 years with a primary diagnosis of craniosynostosis (International Classification of Diseases, Ninth Revision, 756.0; International Classification of Diseases, Tenth Revision, Q75.0) and CPT code for craniotomy (61550 to 61559). Tranexamic acid use, complications, length of stay, and transfusion requirements were recorded. Subgroup analysis was performed for fronto-orbital advancements and single-suture surgery. RESULTS: A total of 1345 patients were identified. Mean patient age was 229 ± 145 days. Four hundred fifty-four patients (33.7 percent) received tranexamic acid. Tranexamic acid use increased from 13.1 percent in 2010 to 75.6 percent in 2018 (p = 0.005), and mean blood products per patient increased from 1.09 U to 1.6 U (p = 0.009). Surgical complication rate was higher in those receiving tranexamic acid (16.7 percent versus 11.1 percent; p = 0.004). Tranexamic acid administration was associated with increased transfusion requirements on univariate and multivariate analysis (1.76 U versus 1.18 U; OR, 2.03; p < 0.001). In the fronto-orbital advancement subgroup, those receiving tranexamic acid received more total blood products (2.2 U versus 1.8 U; p = 0.02); this difference was present but not significant within the single-suture group (0.69 U versus 0.50 U; p = 0.06). CONCLUSIONS: Tranexamic acid use in craniosynostosis surgery has increased dramatically since 2010. However, it was associated with higher transfusion and complication rates in this data set. Optimization of its use and blood loss mitigation in infant craniosynostosis deserve continued research. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

Aim: To evaluate dermal regeneration scaffolds custom-fabricated from fibril-forming oligomeric collagen where the total content and spatial gradient of collagen fibrils was specified. Materials & methods: Microstructural and mechanical features were verified by electron microscopy and tensile testing. The ability of dermal scaffolds to induce regeneration of rat full-thickness skin wounds was determined and compared with no fill control, autograft skin and a commercial collagen dressing. Results: Increasing fibril content of oligomer scaffolds inhibited wound contraction and decreased myofibroblast marker expression. Cellular and vascular infiltration of scaffolds over the 14-day period varied with the graded density and orientation of fibrils. Conclusion: Fibril content, spatial gradient and orientation are important collagen scaffold design considerations for promoting vascularization and dermal regeneration while reducing wound contraction.

RESUMO

Background: Carpal tunnel syndrome is a common cause of upper extremity discomfort. Surgical release of the median nerve can be performed under general or local anesthetic, with or without a tourniquet. Wide-awake carpal tunnel release (CTR) (local anesthesia, no sedation) is gaining popularity. Tourniquet discomfort is a reported downside. This study reviews outcomes in wide-awake CTR and compares tourniquet versus no tourniquet use. Methods: Wide-awake, open CTRs performed from February 2013 to April 2016 were retrospectively reviewed. Patients were divided into 2 cohorts: with and without tourniquet. Demographics, comorbidities, tobacco use, operative time, estimated blood loss, complications and outcomes were compared. Results: A total of 304 CTRs were performed on 246 patients. The majority of patients were male (88.5%), and the mean age was 59.9 years. One hundred patients (32.9%) were diabetic, and 92 patients (30.2%) were taking antithrombotics. Seventy-five patients (24.7%) were smokers. A forearm tourniquet was used for 90 CTRs (29.6%). Mean operative time was 24.97 minutes with a tourniquet and 21.69 minutes without. Estimated blood loss was 3.16 mL with a tourniquet and 4.25 mL without. All other analyzed outcomes were not statistically significant. Conclusion: Operative time was statistically longer and estimated blood loss was statistically less with tourniquet use, but these findings are not clinically significant. This suggests that local anesthetic with epinephrine is a safe and effective alternative to tourniquet use in CTR. The overall rate of complications was low, and there were no major differences in postoperative outcomes between groups.

RESUMO

BACKGROUND: An estimated 800,000 dog bites require medical attention every year. The purpose of this study is to review the characteristics of dog bite injuries in children and examine temporal trends. METHODS: The Kids' Inpatient Database was used to identify pediatric patients with dog bite injuries over a 10-y period. Demographic data, primary payer, injury characteristics, length of hospitalization, and treatments were recorded. Statistical analysis was performed in SAS 9.3 (SAS Institute Inc, Cary, NC). RESULTS: A total of 6308 patients were identified. Average age at time of injury was 6.4 ± 4.3 y. Children under age 5 y were the most affected subgroup (39.3% in 2000 versus 44.7% in 2009, P < 0.001). Most bites were to the head/neck and significantly increased from 53.9% in 2000 to 60.1% in 2009. Cellulitis complicated many injuries (33.7% in 2000 versus 44.8% in 2009, P < 0.001). Overall, 50% of patients underwent a procedure; 31% had an invasive surgical procedure; and 5.1% of patients required skin grafts or flaps. CONCLUSIONS: Dog bites are a common cause of pediatric injuries and are a significant burden on families and the health care system. Evaluating the characteristics of these injuries can guide educational efforts.

RESUMO

BACKGROUND: Oral mucosa expansion before ridge augmentation is a procedure to reduce soft tissue exposure and to improve bone graft density and volume after augmentation. This study explored a novel, shapeable hydrogel tissue expander (HTE) in intraoral sites that had undergone previous expansion and surgery. METHODS: Nine beagle dogs had all premolar teeth extracted and adjacent alveolar bone reduced. After at least 3 months healing hydrogels were placed at 4 sites in each dog: maxilla and mandible, right and left. After 6 weeks of expansion, the hydrogels were removed and measured for volume expansion and physical condition. Punch biopsies were taken of the expanded oral mucosa. After 3 months, a second hydrogel insertion was performed at each of the same sites. After this second expansion cycle, volume and hydrogel condition were recorded. Three dogs received ultrasound imaging of the hydrogels during the second expansion. Necropsy specimens were taken of both expanded and non-expanded oral mucosa. RESULTS: Within 2 weeks after HTE insertion in both first and second insertions, blood flow returned to the pre-insertion level. The first and second insertions resulted in linear oral mucosa gain of 8.13 mm, and 6.44 mm, respectively. First and second insertion hydrogels erupted from 4% of the first expansion sites, and 3% of the second expansion sites. There was no directional migration of the expanding hydrogel at any site. Histology found little inflammatory reaction to any hydrogel implant. CONCLUSION: Oral mucosa can be consistently and successfully expanded before bone graft for ridge augmentation even at sites with a history of prior surgeries.

RESUMO

BACKGROUND: The number of women in medicine has grown rapidly in recent years. Women constitute over 50% of medical school graduates and hold 38% of faculty positions at United States medical schools. Despite this, gender disparities remain prevalent in most surgical subspecialties, including plastic surgery. The purpose of this study was to analyze gender authorship trends. MATERIALS AND METHODS: A cross-sectional study of academic plastic surgeons was performed. Data were collected from departmental websites and online resources. National Institute of Health (NIH) funding was determined using the Research Portfolio Online Reporting Tools database. Number of published articles and h-index were obtained from Scopus (Elsevier Inc, New York, NY). Statistical analysis was performed in SPSS (SPSS Inc, Chicago, IL). RESULTS: A total of 814 plastic surgeons were identified in the United States. Compared to men, women had significantly fewer years in practice (P <0.001), lower academic ranks (P <0.001), and published less (P <0.001). There was no difference in the number of PhD degrees between genders; women with PhDs published less than men with PhDs (P = 0.04). 5.1% of women and 6.9% of men received NIH funding during their career (P = 0.57). There was no gender difference in scholarly output among NIH-funded surgeons. Overall, years in practice, academic rank, chief/program director title, advanced degrees, and NIH funding all positively correlated with academic productivity. CONCLUSIONS: This study identifies significant gender disparities in scholarly productivity among plastic surgeons in academia. Future efforts should focus on improving gender equality and eliminating barriers to academic development.

RESUMO

BACKGROUND: Soft-tissue deficiencies pose a challenge in a variety of disease processes when the end result is exposure of underlying tissue. Although multiple surgical techniques exist, the transposition of tissue from one location to another can cause donor-site morbidity, long incisions prone to dehiscence, and poor patient outcomes as a result. Use of tissue expansion prior to grafting procedures has been shown to have success in increasing available soft tissue to aid in repairing wounds. However, the current tissue expanders have biomechanical limits to the extent and rate of expansion that usually exceeds the tissue capacity, leading to incisional dehiscence or expander extrusion. Understanding the baseline biomechanical properties of the tissue to be expanded would provide useful information regarding surgical protocol employed for a given anatomical location. Therefore, the aim of this study was to test and compare the baseline (preexpansion) biomechanical properties of different common expansion sites in dogs. METHODS: Four samples measuring approximately 20 × 15 × 1 mm were harvested from 8 dogs. The samples were collected from the hard palate, alveolar mucosa, scalp, and chest of the animal and analyzed for stress, strain, maximum tangential stiffness, maximum tangential modulus, and tensile strength using a Texture Technologies TA.XT texture analyzer with corresponding biomechanical measurement software. Samples were compared as to their baseline biomechanical properties prior to any soft-tissue expansion. Histological sections of the samples were analyzed using hematoxylin eosin in an attempt to correlate the histological description to the biomechanical properties seen during testing. Summary statistics (mean, standard deviation, standard error, range) are reported for stress, strain, maximum tangential stiffness, maximum tangential modulus, and tensile strength and for the histological parameters by intraoral site. Analysis of variance was used to compare the biomechanical and histological parameters among the 4 locations while accounting for multiple measurements from each dog. RESULTS: The scalp had significantly higher maximum stress (σmax) than chest, mucosa, and palate (P < 0.0001), with no differences among the other 3 locations (P > 0.63). Scalp site also had significantly higher maximum tangential modulus (ε) than chest, mucosa, and palate (P < 0.006), with no differences among the other 3 locations (P > 0.17). The locations did not have significantly different maximum tangential stiffness (k; P = 0.72). Histologically, 2 separate patterns of collagen disruption were evident. CONCLUSION: Although different results were obtained than theorized, this study showed that the scalp had the greatest resiliency to expand prior to tearing, and the highest tangential modulus, with all sites having statistically similar modulus of elasticity. Based on this study, the scalp could be expanded more aggressively compared with the other sites.

RESUMO

OBJECTIVE: The aim of this study was to determine whether molar incisor hypomineralization (MIH) is greater in patients with cleft lip and palate (CLP) who underwent primary alveolar grafting (PAG) as compared with CLP waiting for secondary alveolar grafting (SAG) and with controls. DESIGN: A retrospective analysis of intraoral photographs of 13 CLP patients who underwent a PAG, 28 CLP prior to SAG, and 60 controls without CLP was performed. Mantel-Haenszel χ tests were used to compare the 3 groups for differences in MIH scores, and Wilcoxon rank sum tests were used to compare the groups for differences in average MIH scores. A 5% significance level was used for all tests. RESULTS: Molar incisor hypomineralization scores were significantly higher for the PAG and SAG groups compared with the control group (P < 0.001). The PAG group had significantly higher incisor MIH (P = 0.016) compared with the SAG group. Molar incisor hypomineralization average scores were significantly higher for the 2 graft groups compared with the controls (P < 0.0001). The PAG group had significantly higher average MIH score and average MIH score for incisors compared with the SAG group (P = 0.03). CONCLUSIONS: Cleft lip and palate patients have significantly greater MIH compared with controls, and CLP patients with PAGs have significantly greater MIH in the incisor region compared with CLP patients with SAGs, indicating that subjects with PAGs have more severely affected dentition.

RESUMO

BACKGROUND: Vascularized lymph node transfer is an increasingly popular option for the treatment of lymphedema. The omental donor site is advantageous for its copious soft tissue, well-defined collateral circulation, and large number of available nodes, without the risk of iatrogenic lymphedema. The purpose of this study is to define the anatomy of the omental flap in the context of vascularized lymph node harvest. METHODS: Consecutive abdominal computed tomography angiography (CTA) images performed at a single institution over a 1-year period were reviewed. Right gastroepiploic artery (RGEA) length, artery caliber, lymph node size, and lymph node location in relation to the artery were recorded. A two-tailed Z-test was used to compare means. A Gaussian Mixture Model confirmed by normalized entropy criterion was used to calculate three-dimensional lymph node cluster locations along the RGEA. RESULTS: In total, 156 CTA images met inclusion criteria. The RGEA caliber at its origin was significantly larger in males compared with females (p < 0.001). An average of 3.1 (1.7) lymph nodes were present per patient. There was no significant gender difference in the number of lymph nodes identified. Average lymph node size was significantly larger in males (4.9 [1.9] × 3.3 [0.6] mm in males vs. 4.5 [1.5] × 3.1 [0.5] mm in females; p < 0.001). Three distinct anatomical variations of the RGEA course were noted, each with a distinct lymph node clustering pattern. Total lymph node number and size did not differ among anatomical subgroups. CONCLUSION: The omentum is a reliable lymph node donor site with consistent anatomy. This study serves as an aid in preoperative planning for vascularized lymph node transfer using the omental flap.
