Timing of Autologous Tissue Breast Reconstruction Does Not Affect Free Flap Failure

ABSTRACT

This study aimed to determine whether there is a difference in free flap failure based on the decision to undergo immediate versus delayed autologous tissue breast reconstruction after mastectomy. The National Surgical Quality Improvement Program database was queried for breast free flap procedures performed between 2015 and 2020. This study demonstrates that the decision to undergo immediate versus delayed autologous tissue breast reconstruction does not have a significant association with free flap failure. This remains true regardless of whether patients undergo unilateral mastectomy with reconstruction or whether patients choose to also undergo contralateral prophylactic mastectomy with reconstruction.

Complications and Risks Associated with the Different Types of Abdominoplasties: An Analysis of 55,956 Patients

BACKGROUND

Different types of abdominoplasties have been developed to address individual patient characteristics. However, complication rates and risk factors for complications between different types of abdominoplasties has yet to be reported.

OBJECTIVES

The aim of this study was to evaluate the complication rates and risks associated with each type of abdominoplasty.

METHODS

Using the CosmetAssure database, patients undergoing an abdominoplasty from 2015 to 2022 were identified. Demographic factors and major complications were recorded and analyzed using a chi-square test or ANOVA. A logistic regression was performed to identify the risk associated with each type of abdominoplasty for developing complications.

RESULTS

A total of 55,596 patients underwent an abdominoplasty procedure by any method. The overall complication rate was 2.1%. There was a significant difference in the overall complication rate between all seven types of abdominoplasties (p<0.05), with Fleur-de-lis abdominoplasty having the highest complication rate. The year of surgery, being underweight or morbidly obese, diabetes, and being male placed patients at a significantly higher risk for developing a post-operative complication. Over 15,000 patients (27.2%) had concurrent procedures related to breast surgery, other body contouring, liposuction, or facial surgery. When accounting for various risk factors in a regression model, there was no significant added risk for major complications after a combination procedure with an abdominoplasty compared to abdominoplasty alone.

CONCLUSIONS

Among the different types of abdominoplasties, a Fleur-de-lis abdominoplasty has the highest complication rate. Concurrent cosmetic procedures in addition to an abdominoplasty showed no added risk for major complications compared to abdominoplasty alone.

Patient Characteristics and Spending Among Individuals Undergoing Ambulatory Panniculectomy and Abdominoplasty in the US from 2016 to 2019

BACKGROUND

Abdominal contouring surgery can provide both functional and cosmetic benefits to patients with abdominal soft tissue laxity. Although these procedures have been studied in the inpatient setting, few studies describe abdominal contouring surgery in the ambulatory setting.

OBJECTIVE

The purpose of this analysis was to investigate patterns in patient demographics between functional panniculectomy and cosmetic abdominoplasty using national data from the last four years.

METHODS

Using the Nationwide Ambulatory Surgery Sample, we analyzed outpatient abdominal contouring procedures between 2016 and 2019. Encounters with a CPT 15830 were included. Procedures with ICD Z41.1 or CPT 15847 modifiers were defined as cases of cosmetic abdominoplasty.

RESULTS

A weighted estimate of 95,289 encounters were included, with 66,531 (69.8%) functional panniculectomy and 28,758 (30.2%) cosmetic abdominoplasty procedures. Among patients with a history of bariatric surgery (23.8%; 95% CI, 22.3-25.4%), there was a 28.5% (4,866 in 2016 vs 6,254 in 2019) increase in panniculectomy and abdominoplasty. Compared with individuals who underwent cosmetic abdominoplasty, individuals who underwent functional panniculectomy were more racially diverse, had more comorbidities, and were more likely to be from low-income backgrounds.

CONCLUSIONS

Rates of abdominal contouring surgery in the ambulatory setting have increased in recent years especially among individuals with previous bariatric surgery. There are important demographic and clinical differences between patients who underwent functional panniculectomy and cosmetic abdominoplasty including primary payer, comorbidities, and racial identity.

Abdominal donor-site complications following autologous breast reconstruction: A multi-institutional multisurgeon study

BACKGROUND

The deep inferior epigastric perforator (DIEP) free flap is the gold standard procedure for autologous breast reconstruction. Although breast-related complications have been well described, donor-site complications and contributing patient risk factors are poorly understood.

METHODS

We examined a multi-institutional, prospectively maintained database of patients undergoing DIEP free flap breast reconstruction between 2015 and 2020. We evaluated patient demographics, operative details, and abdominal donor-site complications. Logistic regression modeling was used to predict donor-site outcomes based on patient characteristics.

RESULTS

A total of 661 patients were identified who underwent DIEP free flap breast reconstruction across multiple institutions. Using logistic regression modeling, we found that body mass index (BMI) was an independent risk factor for umbilical complications (odds ratio [OR] 1.11, confidence interval [CI] 1.04-1.18, p = 0.001), seroma (OR 1.07, CI 1.01-1.13, p = 0.003), wound dehiscence (OR 1.10, CI 1.06-1.15, p = 0.001), and surgical site infection (OR 1.10, CI 1.05-1.15, p = 0.001) following DIEP free flap breast reconstruction. Further, immediate reconstruction decreases the risk of abdominal bulge formation (OR 0.22, CI 0.108-0.429, p = 0.001). Perforator selection was not associated with abdominal morbidity in our study population.

CONCLUSIONS

Higher BMI is associated with increased abdominal donor-site complications following DIEP free flap breast reconstruction. Efforts to lower preoperative BMI may help decrease donor-site complications.

Randomized Controlled Trial Comparing Liposomal to Plain Bupivacaine in the Transversus Abdominis Plane for DIEP Flap Breast Reconstruction

BACKGROUND

Pain control after autologous breast reconstruction is important for patient satisfaction and early recovery. Transversus abdominis plane (TAP) blocks are commonly used as part of an enhanced recovery after surgery (ERAS) pathway for breast reconstruction. It is uncertain whether liposomal bupivacaine used in TAP blocks offers additional advantages. This study aimed to compare the efficacy of liposomal bupivacaine versus plain bupivacaine for patients undergoing deep inferior epigastric perforator flap reconstruction.

METHODS

This double-blinded randomized controlled trial studied patients undergoing abdominally based autologous breast reconstruction between June of 2019 and August of 2020. Subjects were randomly assigned liposomal or plain bupivacaine, performed using ultrasound-guided TAP block technique. All patients were managed according to an ERAS protocol. Primary outcomes were postoperative narcotic analgesia required, measured in oral morphine equivalents from postoperative days 1 to 7. Secondary outcomes included numeric pain scale score on postoperative days 1 to 7, nonnarcotic pain medication use, time to first narcotic use, return of bowel function, and length of stay.

RESULTS

Sixty patients were enrolled: 30 received liposomal bupivacaine and 30 received plain bupivacaine. There were no significant differences in demographics, daily oral morphine equivalent narcotic use, nonnarcotic pain medication use, time to narcotic use, numeric pain scale score, time to bowel function, or length of stay.

CONCLUSION

Liposomal bupivacaine does not confer advantages over plain bupivacaine when used in TAP blocks for abdominally based microvascular breast reconstruction in patients under ERAS protocols and multimodal approaches for pain control.

Investigating the Contraction Pattern of the Zygomaticus Major Muscle and its Clinical Relevance: A Functional MRI Study

BACKGROUND

Our understanding of facial anatomy has significantly evolved, yet the detailed contraction patterns of facial muscles and their presentation during clinical imaging remain largely unexplored. Understanding the contraction patterns and visual presentation of these muscles, particularly the zygomaticus major could enhance pre-surgical facial assessments and the development of new treatment strategies.

METHODS

A total of 34 healthy young individuals (17 female, 17 male) with a mean age of 23.6 (2.4) years [range: 20-30] were investigated regarding the length, thickness, width, and angle of the zygomaticus major muscle in five different facial expressions (i.e., repose, anger, joy, surprise, and sadness) utilizing MR imaging.

RESULTS

Joyful expressions caused a reduction in muscle length to 85.6% of its original length and an increase in width (103.4%), thickness (108.4%), and facial angle (2.72°) when compared to that in repose, suggesting isotonic contraction. Conversely, expressions of anger, surprise, and sadness generally led to muscle stretching, seen through changes in length (98.9%, 104.3%, and 102.7%, respectively), width (98.8%, 96.5%, and 99.4%, respectively), and thickness (91.2%, 91.0%, and 102.7%, respectively), with variable alterations in facial angle (0.55°, 1.85°, and 1.00°, respectively) depending on the specific expression.

CONCLUSION

This MRI-based study indicates that the zygomaticus major muscle experiences isotonic contraction, characterized by decreased length and increased width and thickness. The findings underline the importance of muscle thickness as a reliable parameter in assessing facial muscle function and offer valuable guidance for practitioners in accurately evaluating muscle performance during different facial expressions.

Assessment of x-ray efficacy for intraoperative microneedle retrieval using a cadaveric model

INTRODUCTION

Institutional protocols often mandate the use of x-rays when a microneedle is lost intraoperatively. Although x-rays can reliably show a macroneedle, the benefit of x-rays in detecting microneedles in human tissues has not been established as available data on this topic are investigated in anthropometric models. The current study aims to evaluate whether x-rays can reliably detect retained microneedles in a human cadaveric model. We hypothesize that microneedles would be detected at a significantly lower rate than macroneedles by x-ray in human tissues.

MATERIALS AND METHODS

Needles ranging from 4-0 to 10-0 were placed randomly throughout a cadaveric hand and foot. Each tissue sample was x-rayed using a Fexitron X-Ray machine, taking both anteroposterior and lateral views. A total of six x-ray images were then evaluated by 11 radiologists, independently. The radiologists circled over the area where they visualized a needle. The accuracy of detecting macroneedles (size 4-0 to 7-0) was compared with that of microneedles (size 8-0 to 10-0) using a chi-square test.

RESULTS

The overall detection rate for the microneedles was significantly lower than the detection rate for macroneedles (13.5% vs 88.8%, p < .01). When subcategorized between the hand and the foot, the detection rate for microneedles was also significantly lower than the rate for macroneedles (hand: 7.6% for microneedles, 93.2% for macroneedles, p < .01; foot: 19.5% for microneedles, 84.4% for macroneedles, p < .01). The detection rate, in general, significantly decreased as the sizes of needles became smaller (7-0:70.5%, 8-0:18.2%, 9-0:16.7%, 10-0:2.3%, p < .01).

CONCLUSION

X-rays, while useful in detecting macroneedles, had a significantly lower rate of detecting microneedles in a cadaveric model. The routine use of x-rays for a lost microneedle may not be beneficial. Further investigation with fresh tissue and similar intraoperative x-ray systems is warranted to corroborate and support these findings.

National patterns in the use of International Statistical Classification of Diseases and Health Related Problems, tenth revision Z codes in ambulatory surgery from 2016 to 2019

BACKGROUND

In the tenth revision of the International Statistical Classification of Disease and Health Related Problems (ICD-10), Z codes were added to improve documentation and understanding of health-related social needs. We estimated national Z code use in the ambulatory surgery setting from 2016 to 2019.

METHODS

Using the Nationwide Ambulatory Surgery Sample (NASS), we identified encounters for ambulatory surgery with an ICD-10 code between Z55.0 and Z65.9. Data were stratified by Z code domains from the Centers for Medicare and Medicaid Services (CMS).

RESULTS

This analysis of 41,827 ambulatory surgery encounters with documented Z codes found that the most documented determinants of health related to multiparity or unwanted pregnancy, homelessness, and incarceration. There was a 16.1% increase in the use of Z codes from 2016 to 2019.

CONCLUSION

Rates of Z code use in the ambulatory surgery setting are increasing with current documentation serving as a specific but not sensitive measure of socioeconomic need.

Vanderbilt Mini-PROM-Breast for Breast Reconstruction: A Short-Form, Patient-Reported Outcomes Measure

BACKGROUND

Breast reconstruction procedures are among the most commonly performed plastic surgery operations. Although there are well-validated patient-reported outcomes measures (PROMs) for breast reconstruction, there are several patient-, provider-, and service-level barriers to their implementation in routine clinical settings. Therefore, we developed a short-form PROM to evaluate breast reconstruction outcomes.

METHODS

Using a mixed-methods approach, the Vanderbilt Mini-PROM-Breast (VMP-B) was constructed and validated to assess patient-reported outcomes from breast reconstruction. Classic test theory methods were used to evaluate acceptability, reliability, and validity. External validation was subsequently performed using the BREAST-Q as a reference standard.

RESULTS

The VMP-B is a 16-item instrument composed of three domains: quality of life, body image, and breast satisfaction. Psychometric properties including acceptability, reliability, and validity exceeded reference criteria. When tested with 104 patients, the authors found significant benefits of breast reconstruction on quality of life, body image, and breast satisfaction. These results were associated with sizeable effect sizes (g) (g = 0.421, g = 0.520, and g = 1.25) demonstrative of clinically meaningful results. When tested concurrently in 70 patients, the VMP-B and the BREAST-Q showed similar results, exhibiting excellent convergent validity.

CONCLUSIONS

The VMP-B is a validated short-form PROM that reliably assesses breast reconstruction outcomes. As a short form, the VMP-B decreases both patient and provider burden, which allows for routine, point-of-care collection of breast reconstruction outcomes.

Systematic Review and Meta-Analysis of Global Neuroma Incidence in Upper Extremity Amputees

BACKGROUND

Neuromas substantially decrease a patient's quality of life and obstruct the use of prosthetics. This systematic review and meta-analysis aimed to determine the global incidence of neuroma formation in upper extremity amputees.

METHODS

A literature search was performed using 3 databases: Web of Science, MEDLINE, and Cochrane. Inclusion criteria for the systematic review were those studies investigating only upper extremity amputees and reported postamputation neuroma. A random-effects, inverse-variance analysis was conducted to determine the pooled proportion of neuromas within the upper extremity amputation population. Critical appraisal using the JBI Checklist for Studies Reporting Prevalence Data of each individual article were performed for the systematic review.

RESULTS

Eleven studies met the inclusion criteria collating a total of 1931 patients across 8 countries. More than three-fourth of patients are young men (77%; age range, 19-54 years) and had an amputation due to trauma. The random-effects analysis found the pooled combined proportion of neuromas to be 13% (95% confidence interval, 8%-18%). The treatment of neuroma is highly variable, with some patients receiving no treatment.

CONCLUSIONS

The pooled proportion of neuroma incidence in the 1931 patients was 13%. With the known global prevalence of upper extremity amputees, this translates to nearly 3 million amputees suffering from a neuroma globally. Increasing training in preventative surgical methods could contribute to lowering this incidence and improving the outcomes of this patient population.

Patient Perspectives on Selecting an Academic Aesthetic Surgeon: A Qualitative Analysis

BACKGROUND

Growth of the aesthetic surgery marketplace has increased patient choice in provider selection. This study aimed to characterize how patients choose an aesthetic surgeon, identify knowledge gaps in this decision-making process, and understand why patients select academic aesthetic surgeons.

METHODS

A qualitative interview study of aesthetic surgery patients from an academic center was conducted. Purposive sampling maximized representation regarding surgeon, surgery type, and patient demographics. An interview guide was developed in collaboration with content and methodology experts, then refined through pilot testing. Emergent themes were identified using a codebook constructed by grounded theory.

RESULTS

Thematic saturation was achieved with 24 patients. When selecting a surgeon, participants valued bedside manner (24 of 24) and past patients' satisfaction (18 of 24). Most participants (16 of 24) ascribed low importance to board certification. Reasons given for choosing an academic practice included the institution's reputation (13 of 24) and the availability of medical records and other specialties if complications arise (8 of 24). Participants demonstrated knowledge gaps regarding medical training and licensure. No participant (0 of 24) was aware that any licensed physician can offer aesthetic surgery, and nearly all participants (23 of 24) expressed discomfort with this.

CONCLUSIONS

Patients prioritize subjective elements when selecting an aesthetic surgeon, relying less on objective and meaningful qualifications like board certification and training background. Academic aesthetic practice is valued because of reputation and ability to function as a medical home. Given the lack of public understanding regarding physician training, initiatives promoting transparency are needed to ensure that patients can make safe, informed decisions.

Multidimensional Assessment of Patient-Reported Outcomes After Gender-Affirming Surgeries Using a Validated Instrument

INTRODUCTION

Limited literatures used validated instruments to evaluate patient-reported outcomes (PROs) for transgender and gender-diverse population undergoing gender-affirming surgeries (GASs). This study aimed to evaluate PROs using a newly validated psychometric instrument, Vanderbilt Mini Patient-Reported Outcome Measures-Gender (VMP-G).

METHODS

Vanderbilt Mini Patient-Reported Outcome Measures-Gender assesses 4 scales: quality of life, self-concept, satisfaction, and gender dysphoria. Scores range from 20 to 100, with higher scores representing superior PROs. Descriptive analysis was performed, and outcomes were compared in different races/ethnicities, gender identities, age, types of GAS, and time. Patients seeking GAS at Vanderbilt University Medical Center from October 11, 2021, to October 11, 2022, were included. Data were collected anonymously via the Research Electronic Data Capture survey tool at preoperative or postoperative clinic visits.

RESULTS

A total of 207 patients completed VMP-G. Average age was 31.8 years (SD, ±11.5 years). Fifty-three percent of patients were postoperative GAS. In bivariate and linear regression analyses, postoperative patients scored higher on all scales compared with preoperative patients ( P < 0.001). After adjustment, postoperative patients scored 12.5 higher on VMP-G compared with preoperative patients ( P < 0.01). In subset analyses, GAS was associated with improved PROs in White, non-White, binary, and nonbinary and patients younger than 21 years ( P < 0.05). After GAS, patients younger than 21 years reported similar outcomes, compared with patients older than 21 years ( P > 0.05). No PROs differences were reported between patients who underwent top versus bottom surgery ( P = 0.2). Postoperative patients reported low rates of regret (2.8%). Scores on the VMP-G were sustained even 1 year after GAS. Each month after GAS was associated with a score improvement of 0.02 in the gender dysphoria domain after adjusting for patient demographics ( P = 0.02).

CONCLUSIONS

Using a validated GAS-specific measure, we found that surgery sustainably improves patients' self-reported outcomes including gender dysphoria.

Comparison of Complication Rates Between Subpectoral vs Prepectoral Techniques in Prosthetic Breast Reconstruction

BACKGROUND

The location of tissue expanders in implant-based breast reconstruction remains controversial due to variation in surgical techniques and devices.

OBJECTIVES

The aim of this study was 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 undergone 2-stage implant-based breast reconstruction between 2013 and 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

In total, 854 patients were included; 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 and 2.4, respectively) as well as late infection after the second stage of reconstruction (HR, 5.3; all P < .05).

CONCLUSIONS

Location of tissue expanders did not predict risk of complication. However, the prepectoral group was associated with an increased risk of developing infection.

Delayed Versus Immediate Breast Reconstruction in the Ambulatory Surgery Setting: A Cross-Sectional Analysis of the Nationwide Ambulatory Surgery Sample

BACKGROUND

Breast reconstruction remains an important part of a patient's journey after the diagnosis of breast carcinoma and treatment with mastectomy. Although inpatient immediate breast reconstruction has been described, there is a paucity information about whether similar procedures are performed in the ambulatory setting.

OBJECTIVE

The authors sought to investigate rates and patterns for delayed and immediate breast reconstruction in the ambulatory surgery setting using nationally representative data from 2016 to 2019.

METHODS

Using the Nationwide Ambulatory Surgery Sample database, we identified patients with an International Statistical Classification of Disease and Related Health Problems, Tenth Revision, procedure code for breast reconstruction. Demographic and clinical characteristics were recorded for each encounter of breast reconstruction, and linear regression and logistic regression were used to assess for trends and disparities.

RESULTS

National weighted estimates for ambulatory breast reconstruction increased by 15.6% from 89 237 in 2016 to 103 134 in 2019, resulting in 377 109 procedures during the study period. Inflation-adjusted total charges for ambulatory breast reconstruction were $14 billion between 2016 and 2019, or 1.7% of overall charges for ambulatory surgery. Immediate reconstruction was performed in 34.7% (95% CI, 33.4%-36.1%) of cases and increased by 46.9% from 26 930 in 2016 to 39 559 in 2019. Racial disparities were observed in access, comorbidities, and spending.

CONCLUSIONS

Our findings indicate a moderate increase in ambulatory breast reconstruction with a substantial growth in the performance of immediate breast reconstruction in the ambulatory setting.

The Utility of the Plastic Surgery Standardized Letter of Recommendation Form in Predicting Residency Match Outcomes

BACKGROUND

Letters of recommendation play an important role in resident selection. While plastic surgery's Standardized Letter of Recommendation (SLOR) form most commonly serves as an adjunct to narrative letters, the SLOR provides objective data in the review process and could eventually replace narrative letters. The utility of the SLOR in predicting Match outcomes has not been studied.

METHODS

Applicant data from 225 first-time residency applicants in 2020-21 were collected. Logistic regression modeling was used to predict Match outcomes. This model was validated using 100 randomly selected applicants from 2019-20.

RESULTS

Rank placement (SLOR Question 6) was the most important factor when predicting Match outcomes (p<0.0001). All other SLOR questions were not predictive and subject to notable score inflation. No SLOR score differences were noted based on race; female applicants were rated higher in two of ten domains (p<0.05).

CONCLUSIONS

One question on the plastic surgery SLOR was highly predictive of an applicant matching. However, the remaining SLOR questions had little utility and were subject to gross score inflation. Further work should be done to optimize the utility of the SLOR in differentiating applicants. This has important implications in ensuring the selection of professional, competent residents according to the aims of the Accreditation Council of Graduate Medical Education.

Overlapping Surgeries From the Patient's Perspective

INTRODUCTION

Overlapping surgery (OS) occurs when a single surgeon is concurrently caring for patients in multiple operating rooms (OR) but is present for all critical portions of each surgery. Although this is common practice, most studies have found public disapproval of OS. This study aims to better understand attitudes toward OS of patients who gave informed consent for OS.

METHODS

Participant interviews covered topics including trust, OR personnel roles, and attitudes toward OS. Four representative transcripts were distributed among researchers for independent code identification. These were aggregated into a codebook, applied by two coders. Iterative and emergent thematic analyses were done.

RESULTS

Twelve participants were interviewed to reach thematic saturation. Three themes shaped how participants felt about OS: trust in their surgeon, worries about OS, and understanding of OR personnel roles. Factors contributing to trust included personal research and the surgeon's experience. Frequently cited concerns were unpredictability of complications during operations and the surgeon's divided attention. Two participants inaccurately understood personnel roles, believing the surgeon did most or all the hands-on work while trainees were observers. Most participants felt a high or neutral level of comfort toward OS and indicated trust as the reason.

CONCLUSIONS

In contrast to prior research, this study found that most participants had a neutral or positive view of OS. This suggests that a trusting relationship with their surgeon and informed consent are important factors in increasing comfort for OS. Participants who misunderstood OR roles felt less comfortable toward OS. This highlights an opportunity for patient education on trainee roles.

Impact of Tissue Expander Surface Texture on Two-Stage Breast Reconstruction Outcomes: A Combined Analysis of Incidence, Timing, and Severity

BACKGROUND

With ongoing investigations of the impact of device texturing on breast implant-related anaplastic large cell lymphoma (BIA-ALCL), studies have begun comparing complications profiles of tissue expanders. However, there is a paucity of timing and severity data of complications. The aim of this study is to provide a comparative survival analysis of post-operative complications between smooth (STE) and textured tissue expanders (TTE) in breast reconstruction.

METHODS

A single institution experience with tissue expander breast reconstruction was reviewed for complications up to 1 year post 2nd stage reconstruction from 2014-2020. Demographics, comorbidities, operation-related variables, and complications were evaluated. Kaplan-Meier curves, cox proportional hazard models, and a consensus based ordinal logistic regression model were used to compare complication profiles.

RESULTS

Of 919 ttal patients, 65.3% (n=600) received TTEs and 34.7% (n=319) received STEs. There was increased risk of infection (p<0.0001), seroma (p=0.046), expander malposition (p<0.0001), and wound dehiscence (p=0.019) in STEs compared to TTEs. However, there were also decreased risk of capsular contracture (p=0.005) in STEs compared to TTEs. Failure of breast reconstruction (p<0.001) and wound dehiscence (p=0.018) occurred significantly earlier in STEs compared to TTEs. Predictors for significantly higher severity complications included: smooth tissue expander use (p=0.007), shorter time to complication (p<0.0001), higher BMI (p=0.005), smoking history (p=0.025), and nipple sparing mastectomy (p=0.012).

CONCLUSIONS

Differences in the timing and severity of complications contribute to the safety profiles of tissue expanders. STEs are associated increased odds of higher severity and earlier complications. Therefore, tissue expander selection may depend on underlying risk factors and severity predictors.

Examination of Outcome Disparities in Reports of Prepectoral and Subpectoral Direct-to-Implant Reconstruction: A Systematic Review and Meta-analysis

BACKGROUND

There are mixed results in surgical complications regarding the usage of prepectoral versus subpectoral implant placement in direct-to-implant breast reconstruction. This study aimed to provide a comprehensive synthesis of surgical complications between the subpectoral and prepectoral reconstructive method.

METHODS

PubMed, Embase, and Cochrane were searched for literature published up until December 2022. Studies that compared subpectoral and prepectoral breast reconstruction and reported at least one postoperative complication were included. The following 8 major outcomes were included: revision and reoperation, capsular contracture, explantation, seroma, hematoma, infection, skin necrosis, and animation deformity. Systematic review and meta-analysis were performed to compare outcomes of the 2 techniques. Subgroup analysis was performed to compare whether practice differences in different countries may have an impact on outcomes.

RESULTS

A total of 18 studies were identified in our literature search. Two thousand three hundred sixty patients were included, representing a total of 3135 breasts. Our analysis demonstrated that prepectoral reconstruction had significantly lower odds of developing postoperative hematoma [odds ratio (OR), 0.62; P = 0.05], seroma (OR, 0.67; P = 0.01), infection (OR, 0.64; P = 0.03), revision and reoperation (OR, 0.44; P < 0.00001), and animation deformity (OR, 0.01; P < 0.00001), compared with the subpectoral method. Subgroup analysis showed that differences between 3 countries (United States, Korea, Italy) are low (all subgroup heterogeneity test P > 0.1).

CONCLUSIONS

While both subpectoral and prepectoral are safe methods for breast reconstruction, the prepectoral technique may lead to lower odds of developing multiple major postoperative complications.

Gender-Affirming Chest Reconstruction Among Transgender and Gender-Diverse Adolescents in the US From 2016 to 2019

This cross-sectional study examines the incidence, demographic characteristics, and cost associated with masculinizing and feminizing chest surgical procedures among individuals younger than 18 years.

Measuring Biomechanical Properties Using a Noninvasive Myoton Device for Lymphedema Detection and Tracking: A Pilot Study

Background

Improved techniques for lymphedema detection and monitoring of disease progression are needed. This study aims to use the noninvasive MyotonPRO Device to detect differences in biomechanical skin characteristics in patients with breast cancer-related lymphedema (BCRL).

Methods

The handheld Myoton device was used to measure skin parameters including dynamic skin stiffness, oscillation frequency (tone), mechanical stress relaxation time, and creep in 11 women diagnosed with BCRL. Seven anatomical sites were measured bilaterally for each participant. The average values in the affected arms were compared with those in the contralateral unaffected arms.

Results

Among the 11 female participants with unilateral BCRL Stages 0 to II, the combined averages for dynamic skin stiffness and frequency measurements were decreased in the affected arms when compared with those for the contralateral control arms (ratio < 1). The median ratio of stiffness (affected to unaffected control arm) was 0.91 (interquartile range [IQR] 0.78-1.03) while frequency was 0.94 (IQR 0.89-1.0). Skin relaxation time and creep averages were increased in the affected arms. The relaxation time median ratio (affected to unaffected control arm) was 1.07 (IQR 1.02-1.14) and the median ratio of creep was 1.06 (IQR 1.03-1.16).

Conclusions

This study suggests the Myoton can detect differences in skin biomechanical parameters of the affected and unaffected arms in patients with BCRL. Larger studies are needed to draw strong conclusions.

Nationwide Estimates of Gender-Affirming Chest Reconstruction in the United States, 2016-2019

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 < 0.001). A total 12,751 (59.9%) chest surgeries were covered by private health insurance, 6557 (30.8%) were covered by public health insurance, 1172 (5.5%) were self-pay, and 813 (3.8%) had other means of payment. The median total charges were $29,887 (IQR, $21,778-$43,785) for chest reconstruction overall. Age, expected primary payer, patient location, and median income varied significantly by race (P < 0.001).

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.

Surgical Antibiotic Prophylaxis in Children Undergoing Surgery: A Systematic Review and Meta-Analysis

Background: To establish the role of surgical antibiotic prophylaxis (SAP) in the prevention of surgical site infection (SSI) in children undergoing surgery. Design: A systematic review and meta-analysis of six databases: MEDLINE (PubMed), EMBASE, CINAHL Plus, Cochrane Library, Web of Science, and Scopus. Study Selection: Included studies (irrespective of design) compared outcomes in children undergoing surgery, aged 0 to 21 years who received SAP with those who did not, with SSI as an outcome, using the U.S. Centers for Disease Control and Prevention (CDC) definitions for SSI. Data Extraction: Two independent reviewers applied eligibility criteria, assessed the risk of bias, and extracted data. Results: A total of six randomized control trials and 26 observational studies including 202,593 surgical procedures among 202,405 participants were included in the review. The pooled odds ratio of SSI was 1.20; (95% confidence interval [CI], 0.91-1.58) comparing those receiving SAP with those not receiving SAP, with moderate heterogeneity in effect size between studies (τ² = 0.246; χ² = 69.75; p < 0.001; I² = 57.0%). There was insufficient data on many factors known to be associated with SSI, such as cost, length of stay, re-admission, and re-operation; it was therefore not possible to perform subanalyses on these. Conclusions: This review and metanalysis did not find a preventive action of SAP against SSI, and our results suggest that SAP should not be used in surgical wound class (SWC) I procedures in children. However, considering the poor quality of included studies, the principal message of this study is in highlighting the absence of quality data to drive evidence-based decision-making in SSI prevention in children, and in advocating for more research in this field.

Preoperative Risk Factors and Complication Rates of Breast Augmentation With Fat Grafting

BACKGROUND

The current literature on the complications and risk factors of autologous fat grafting (AFG) for breast augmentation is scant and inconclusive.

OBJECTIVES

The aim of this study was to use a large, multicenter database to determine the major complications and risk factors of patients undergoing breast augmentation with AFG in comparison to breast augmentation with implants.

METHODS

Patients undergoing breast augmentation with AFG as well as with implants between January 2, 2017 and July 31, 2019 were identified from the CosmetAssure database (Birmingham, AL). The primary outcome was the occurrence of major complication(s) requiring emergency department visit, hospital admission, or reoperation within 45 days postoperatively. Age, gender, BMI, smoking, diabetes, facility, ASA class, and anesthetic type were evaluated as risk factors.

RESULTS

Among the 76,128 patients enrolled in CosmetAssure, 789 (1.0%) underwent breast augmentation with AFG, in comparison to 18,544 (24.3%) patients with implants. The incidence of any major complication in the AFG cohort and implant cohort was 3.2% and 2.3%, respectively. Infection was significantly higher in the AFG cohort (1.1% vs 0.5%). Tobacco users were more likely to have any complication, infection, and pulmonary dysfunction/hypoxia on univariate analysis. ASA Class III/IV was more likely to have any complication and infection. On multivariate analysis, smoking was an independent risk factor for any complication (relative risk = 17.1) and infection (relative risk = 20.2).

CONCLUSIONS

Infection and hematoma are the most common major complications in breast augmentation with AFG. Tobacco use is the only independent risk factor for overall complications and infection. Breast augmentation with AFG has a higher infection rate than augmentation with implants.

Successful prevention of secondary burn progression using infliximab hydrogel: A murine model

INTRODUCTION

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.

METHODS

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.

RESULTS

All mice in the treatment cohort demonstrated decreased conversion of burn from partial to full thickness injury (old = p < 0.01, young = p < 0.001) as compared to the control group. Old mice had greater depth of burn than young mice (p < 0.001). There were greater eosinophils in the treatment cohort for both young and old mice, but it did not reach statistical significance.

CONCLUSION

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.

Board Certification in Cosmetic Surgery: An Examination of Online Advertising Practices

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Incidence and Preoperative Risk Factors for Major Complications After Capsulectomy: Analysis of 3048 Patients

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 < 0.05). Capsulectomy patients were more likely to have any complication and specifically hematoma than those undergoing breast implant removal or replacement without capsulectomy (2.8% vs 1.9% and 1.6% vs 0.9%, respectively, P < 0.05). Eighty-four (2.8%) developed at least 1 complication. The most common complications included hematoma (1.6%) followed by infection (0.5%). American Society of Anesthesiologists Class III/IV was an independent risk factor for any complication and BMI ≥30 kg/m2 and office-based surgical suites were risk factors for infection.

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.

A Systematic Review and Meta-analysis on the Incidence of Patients With Lower-Limb Amputations Who Developed Symptomatic Neuromata in the Residual Limb

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.

Functional panniculectomy vs cosmetic abdominoplasty: Multicenter analysis of risk factors and complications

BACKGROUND

Amidst the rising trend of bariatric surgical procedures being performed across the country and around the world, patients seeking functional panniculectomy after massive weight loss represent a different population than those seeking cosmetic abdominoplasty. The purpose of this study was to determine whether certain complications are more likely to occur in patients undergoing functional panniculectomy, as well as identify risk factors that are implicated in the occurrence of adverse events.

METHODS

Retrospective cohort study was conducted of patients undergoing cosmetic abdominoplasty and functional panniculectomy in North America between 2015 and 2019 using the National Surgical Quality Improvement Program database sponsored by the American College of Surgeons. Comorbidities and postoperative complications between these two cohorts were analyzed with appropriate statistics.

RESULTS

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 (p < .001). Overall adverse events (p < .001), medical complications (p = .047), surgical complications (p < .001), related readmission (p < .001), and related reoperation (p < .001) were significantly higher in patients undergoing functional panniculectomy. Surgical complications significantly higher in functional panniculectomy included superficial incisional infection (p < .001), deep incisional infection (p < .001), organ/space infection (p < .001), dehiscence (p = .003), and bleeding requiring transfusion (p = .003).

CONCLUSIONS

Patients undergoing functional panniculectomy are significantly more likely to have comorbidities and experience postoperative wound infection, dehiscence, sepsis, bleeding, related readmission, and related reoperation.

47 Successful Prevention of Secondary Burn Progressions Using Topical Tacrolimus and Infliximab Hydrogel

Introduction

The pathophysiology of partial- to full-thickness burn wound conversion remains poorly understood. Recent studies have demonstrated that an altered inflammatory response may play be implicated in this secondary conversion to deeper wounds. Therefore, reduction in early inflammation may decrease burn severity and morbidity.

Specifically, TNF-ɑ has been shown to detrimentally affect the healing process after injury through a variety of mechanisms. We hypothesized that microcapillary alginate hydrogel loaded with immunosuppressive medications applied to partial-thickness burns would reduce inflammation and prevent further progression to full-thickness burns.

The purpose of this study was to determine whether topical application of infliximab or tacrolimus could decrease burn wound depth.

Methods

Assembly of the microfluidic hydrogels was achieved by embedding microfibers within a hydrogel scaffold composed of an alginate blend. The treatment cohorts received either (1) infliximab loaded hydrogel or (2) tacrolimus skin ointment covered by hydrogel. The control cohort only received an occlusive dressing.

There were 12 young (2-4 months) and 12 old ( >16 months) mice, which were separated into treatment and control cohorts. All mice were anesthetized and given partial thickness burns by a validated scalding protocol. Mice were euthanized on post-burn day 3, and skin samples were taken. Burn depth was evaluated using Vimentin immunostaining.

Results

In young mice, infliximab hydrogel (p=.002) and tacrolimus hydrogel (p=.002) significantly decreased burn depth compared to controls. In old mice, infliximab hydrogel (p=.005) and tacrolimus hydrogel (p< .001) significantly decreased burn depth compared to controls.

In young mice, infliximab and tacrolimus were similarly efficacious (p > .05). In old mice, tacrolimus significantly decreased burn depth compared to infliximab (p=.002).

In controls, old mice had deeper burn wound progression than young mice (p< .001). Similarly, in those treated with infliximab, old mice had deeper burn wound progression than young mice (p=.002). Interestingly, tacrolimus was able to decrease burn wound depth in old mice such that their burn wound thickness was similar to young mice (p >.05).

Conclusions

Application of a novel microcapillary alginate hydrogel infused with infliximab or topical tacrolimus reduced partial- to full-thickness burn wound conversion in mice. Application of immunosuppressive dressings may be a promising avenue for further clinical investigation to reduce morbidity and mortality associated with burn injuries.

A Roadmap to Implementing Venous Thromboembolism Risk Stratification and Mitigation

INTRODUCTION

Venous thromboembolism (VTE) is a life-threatening postoperative complication that carries high morbidity and mortality for plastic surgery patients. In 2011, the American Society of Plastic Surgeons recommended the adoption of a VTE risk stratification and mitigation; however, successful implementation of VTE prophylaxis protocols has not been well described. To address and reduce the VTE burden at our academic center, a risk assessment protocol was implemented for patients undergoing outpatient plastic surgery procedures.

METHOD

All patients who received outpatient plastic surgery between August 2018 and July 2019 were eligible for the VTE modified Caprini risk assessment screening. Sampling of practice patterns was done by chart review from the first week of each month. The study was divided into 3 phases to assess the relationship of screening compliance rates with each protocol change. Compliance was defined as completion of VTE Caprini screening with documentation in patients' charts.

RESULTS

Over the 12-month study period, 277 patients met the inclusion criteria. From August to November 2018 (phase 1), patients were screened at the initial clinic visit with an average compliance rate of 11.1%. In December 2018 (phase 2), patients were screened on the day of surgery, with an average compliance rate of 47.1%. From January to July 2019 (phase 3), surgeons recorded the numerical Caprini score into the patient's electronic medical record with a subsequent compliance rate of 61.3%. The overall compliance during the 12 months was 44.8%. The median calculated Caprini score for this population was 4 (range, 1-7).

CONCLUSIONS

Standardization of VTE risk assessment is vital for patient safety and outcomes. Successful implementation and long-term protocol sustainability are not a simple goal. In this study, protocol compliance greatly improved after tailoring the guidelines to the specific institutional needs and workflow. These results reinforce the importance of continuous protocol review and modification to ensure optimal departmental buy-in and sustainability.

Post-Mastectomy Surgical Pocket Irrigation With Triple Antibiotic Solution vs Chlorhexidine Gluconate: A Randomized Controlled Trial Assessing Surgical Site Infections in Immediate Tissue Expander 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.

Aesthetic Surgery in Plastic Surgery Academia

BACKGROUND

Aesthetic surgery is a critical component of academic plastic surgery. As institutions are placing increased focus on aesthetic surgery, there is an opportunity to identify factors that facilitate the creation and maintenance of successful aesthetic plastic surgery programs.

OBJECTIVES

The aim of this study was to conduct a national survey to evaluate the current state of academic aesthetic surgery and to identify factors that contribute to success.

METHODS

A REDCap 122-question survey was developed and validated by members of the Academic Aesthetic Surgery Roundtable (AASR). The national survey was distributed to department chairs and division chiefs with active ACGME-approved plastic surgery programs (n = 92). Responses underwent Pearson's chi-squared, Wilcoxon rank-sum, and postselection inference analyses. AASR members convened to interpret data and identify best practices.

RESULTS

Responses were received from 64 of 92 queries (69.6%). The multivariate analysis concluded traits associated with successful academic aesthetic surgery practices included the presence of aesthetic surgery-focused, full-time faculty whose overall practice includes >50% aesthetic surgery (P = 0.040) and nonphysician aesthetic practitioners who provide injection services (P = 0.025). In the univariate analysis, factors associated with strong aesthetic surgery training programs included resident participation in faculty aesthetic clinics (P = 0.034), aesthetic research (P = 0.006), and discounted resident aesthetic clinics (P < 0.001).

CONCLUSIONS

The growth of academic aesthetic surgery practices represents a significant opportunity for advancement of resident training, departmental financial success, and diversification of faculty practices. By identifying and sharing best practices and strategies, academic aesthetic surgery practices can be further enhanced.

Actigraphy to Evaluate Changes in Physical Activity After Autologous Breast Reconstruction

PURPOSE

Early ambulation and return to preoperative (baseline) ambulatory level is protective against postoperative venous thromboembolism. The duration of decreased physical activity after surgery is unknown for most procedures, as surgeons typically estimate physical recovery based on subjective patient reporting. This study aims to quantify the time it takes to return to baseline ambulatory status after breast reconstruction using actigraphy devices.

METHODS

Actigraphy devices were used to evaluate preoperative and postoperative physical activity levels in patients undergoing autologous breast reconstruction at a single academic institution. Steps and resting heart rate (HR) were used as metrics of physical activity and physiological state. "Baseline" physical activity was defined by the average daily step count during the 14 days before surgery. "Return to baseline" occurred when the 7-day daily step average was greater than or equal to 95% of their baseline steps. Study participation was considered complete once a patient returned to baseline or surpassed 8 postoperative weeks.

RESULTS

From May 2019 to April 2020, 17 patients were enrolled in the study before deep inferior epigastric perforator breast reconstruction. The mean age was 48.2 years and mean BMI was 27.6. This cohort averaged 7908 ± 3271 preoperative steps. Two patients returned to baseline activity by postoperative day 28. In total, 8 patients returned by postoperative week 8. Preoperative resting HR average was 73.5 ± 9.43 beats per minute. The average resting HR was elevated by 2.59%, 4.28%, and 2.31% at weeks 1, 2, and 3, respectively. The 7-day daily average resting HR had normalized by week 4.

CONCLUSIONS

Return to baseline physical activity after surgery may take longer than previously perceived, particularly after physiologically demanding surgeries, such as free flap breast reconstruction. These findings indicate that surgeons may underestimate the impact of surgery on physical decline and, consequently, may undertreat with venous thromboembolism prophylaxis.

Tools to Increase Resident Aesthetic Clinic Volume

INTRODUCTION

Resident Aesthetic Clinics (RACs) are an important element for training in plastic surgery residency programs. RACs provide increased exposure to aesthetic surgery as well as greater autonomy in clinical decision making. In an effort to increase RAC volume and thereby enhance resident education, we made two important changes to our operations. First, we reduced the resident surgeons' fees by 75%, and second, we began utilizing social media to promote our residency program and their involvement in aesthetic surgery.

METHODS

Total RAC cases were queried using a RAC specific billing code and individual chief resident case logs for quality control. To generate an accurate timeframe, cases and procedures were compared from 18 months before and after the implemented changes.

RESULTS

We found that the number of cases and procedures increased by 135% and 255%, respectively. The five most commonly performed procedures were liposuction, augmentation mammoplasty, abdominoplasty, mastopexy, and rhytidectomy.

CONCLUSION

By both reducing the resident surgeons' fee and promoting the RAC on social media, we have demonstrated a pronounced increase in both cases and procedures performed by residents. As other institutions seek to increase resident exposure to aesthetic surgery, they may consider similar changes to these.

Histoplasmosis of the Upper Extremities: Clinical Case, Treatment Algorithm, and Systematic Review

Background: Histoplasmosis of the upper extremities is extremely rare, and there is no consensus in its management. The aim of this study was to present a case report and literature review of histoplasmosis in the upper extremities to provide the best treatment recommendation and to increase awareness of this disease. Methods: A systematic review of the literature was performed in PubMed, MEDLINE, and EMBASE databases with the search terms "(Tenosynovitis AND histoplasmosis)" OR "(Upper limbs AND histoplasmosis)" OR "(Upper extremities AND histoplasmosis)" OR "((finger OR arm OR hand OR forearm OR wrist) AND histoplasmosis)." Manuscripts were included in the study if they described diagnosis of histoplasmosis in the bone, joint, synovia, or tendons of the upper extremities. Results: In all, 14 manuscripts and 15 cases of histoplasmosis of the upper extremities from 1992 to 2015 met the inclusion criteria. Eight (53.3%) patients were diagnosed with tenosynovitis, 5 (33.3%) with osteomyelitis, 1 (6.7%) with carpal tunnel syndrome, and 1 (6.7%) with joint wrist abscess. Immunosuppression, travel history, previous diagnosis with histoplasmosis, and persistent symptoms may suggest infectious causes. Surgery and medical treatment together are recommended to optimize outcomes compared with single treatment alone. Conclusions: Histoplasmosis of the upper extremities may have various clinical presentations, including tenosynovitis, osteomyelitis, carpal tunnel syndrome, and joint wrist abscess. The type of surgical approach may depend on the etiology of disease. Increased awareness and knowledge of the clinical signs, symptoms, and effective treatment modalities will help decrease possible complications, such as tendon rupture and functional impairment of the upper extremities.

Initial findings in traumatic peripheral nerve injury and repair with diffusion tensor imaging

OBJECTIVE

Management of peripheral nerve injuries requires physicians to rely on qualitative measures from patient history, electromyography, and physical exam. Determining a successful nerve repair can take months to years for proximal injuries, and the resulting delays in clinical decision-making can lead to a negative impact on patient outcomes. Early identification of a failed nerve repair could prevent permanent muscle atrophy and loss of function. This study aims to test the feasibility of performing diffusion tensor imaging (DTI) to evaluate injury and recovery following repair of wrist trauma. We hypothesize that DTI provides a noninvasive and reliable assessment of regeneration, which may improve clinical decision-making and alter the clinical course of surgical interventions.

METHODS

Clinical and MRI measurements from subjects with traumatic peripheral nerve injury, carpal tunnel syndrome, and healthy control subjects were compared to evaluate the relationship between DTI metrics and injury severity.

RESULTS

Fractional anisotropy from DTI was sensitive to differences between damaged and healthy nerves, damaged and compressed nerves, and injured and healthy contralateral nerves. Longitudinal measurements in two injury subjects also related to clinical outcomes. Implications of other diffusion measures are also discussed.

INTERPRETATION

DTI is a sensitive tool for wrist nerve injuries and can be utilized for monitoring nerve recovery. Across three subjects with nerve injuries, this study has shown how DTI can detect abnormalities between injured and healthy nerves, measure recovery, and determine if re-operation was successful. Additional comparisons to carpal tunnel syndrome and healthy nerves show that DTI is sensitive to the degree of impairment.

Evaluation of plastic surgery resident aesthetic clinic websites

Background

The purpose of the present study was to evaluate the website pages of integrated plastic and reconstructive surgery resident aesthetic clinics in the United States.

Methods

Website pages dedicated to resident aesthetic clinics in all integrated plastic and reconstructive surgery residency programs (n = 79) were accessed between October and November 2019 and evaluated across several criteria, including: number of pages, procedures offered, faculty participation, respective prices, patient photographs, patient testimonials, contact information, and specific recruitment incentives.

Results

Seventy-nine integrated and 54 independent residency programs were identified, 31 of which had both an integrated and an independent residency program for a total of 102 distinct programs. Out of these, only 11 programs (10.8%) had a webpage dedicated to their resident aesthetic clinic (Figure 1). Twelve other programs (13.7%) that did not have a dedicated webpage mentioned a resident aesthetic clinic elsewhere on their residency program website. For each of the eleven programs with space for the resident aesthetic clinic, there was exactly one dedicated webpage. None of the programs with dedicated webpages included photographs of before and after cases, nor procedures performed, nor a listing of resident aesthetic clinic prices. Three of the dedicated webpages included information about faculty participation. Out of the 24 ASAPS endorsed aesthetic fellowship programs, 6 (25%) had a webpage dedicated to the fellow aesthetic clinic. Four of these webpages were comprised of a single webpage, while one program had 6 webpages and one program had 8 webpages. Only one program's webpage included before and after pictures. Four programs (16.7%) included information about faculty participation on the webpage. Five out of the 6 programs had a procedure list on the webpage.

Discussion

Resident aesthetic clinic websites are an important tool in recruiting patients as well as medical students. Addressing the lack and quality of such websites may improve recruitment of patients and students to plastic and reconstructive surgery residency programs. As a primary source of information for potential future residents and patients, plastic and reconstructive surgery programs need to maximize the content and utility of their websites.

Amelanotic melanoma of the head and neck: analysis of tumor characteristics from the National Cancer Database

BACKGROUND

Amelanotic melanoma is an extremely rare subtype of cutaneous melanoma. The tumor characteristics are still not well understood, especially for those located in the head and neck.

METHODS

Tumor characteristics of patients diagnosed with amelanotic melanoma of the head and neck (AMHN) from January 1, 2004, to December 31, 2015, were analyzed by querying the National Cancer Database. Characteristics of AMHN were subsequently compared with common malignant melanoma of the head and neck (CMMHN).

RESULTS

Three hundred and sixty-eight patients were diagnosed with AMHN, and 69,267 were diagnosed with CMMHN. Of those with AMHN, 128 (34.8%) had melanoma located on the scalp and neck, and 172 (46.7%) were diagnosed with an early disease stage (i.e., 0, I, or II). When compared with CMMHN, patients with AMHN were more likely to be diagnosed after 80 years of age (25.3% vs. 18.2%; odds ratio [OR], 3.28; 95% CI, 1.09-9.84; P = 0.03), when Breslow depth was between 2.01 and 4.00 mm (28.5% vs. 6.5%; OR, 1.92; 95% CI, 1.15-3.19; P = 0.01), when ulceration was present (36.7% vs. 9.0%; OR, 1.99; 95% CI, 1.34-2.97; P = 0.001), and when mitotic count was 1 or more/mm² (40.5% vs. 12.8%; OR; 2.53; 95% CI, 1.09-5.89; P = 0.03). No statistical difference was found for sex, specific location, stage, or lymph node involvement.

CONCLUSION

Our study determined that AMHN is associated with older age, increased Breslow depth, presence of ulceration, and greater mitotic count when compared with CMMHN.
