RESUMO
The principles of achieving an aesthetically pleasing and harmonious facial appearance are influenced by our evolving understanding of the three-dimensional topography of the face coupled with novel approaches to midface volumization and contouring. In parallel with the evolving landscape of facial aesthetic surgery, an increasing number of publications have emerged focusing on the role of intraoral buccal fat pad removal (BFPR) for the purposes of aesthetic midface contouring. The authors sought to emphasize an underreported and potentially preventable and untoward complication involving iatrogenic parotid duct injury following BFPR. The purpose of this publication is 3-fold: (1) to review the relevant anatomy and literature on intraoral BFPR, (2) to present a case example of this complication, and (3) to discuss treatment options as part of a proposed management algorithm. The authors detail the surgical indications for performing BFPR and review the relevant anatomic considerations. Complication prevention strategies are outlined, and details regarding avoidance of parotid duct injury are reviewed. The diagnostic criteria and clinical presentation of parotid duct injuries following BFPR are comprehensively outlined. The authors present a clinically actionable algorithm for managing a suspected or diagnosed parotid duct injury following BFPR. A clinical case example is discussed to highlight this complication, the diagnostic criteria, and the systematic and algorithmic approach to management. Intraoral BFPR is an incredibly valuable and powerful procedure that can improve facial contour in patients with buccal lipodystrophy or buccal fat pad pseudoherniation. The authors propose a proper diagnostic approach and treatment algorithm to manage this untoward complication.
RESUMO
Specialty exposure is most influential in a medical student's decision to pursue plastic surgery training. We aimed to understand what opportunities exist for students through national plastic surgery organizations. Methods: The American Board of Plastic Surgery, American Society of Plastic Surgeons, and The Aesthetic Society provide online lists of related organizations. Cross-referencing lists yielded 47 unique organizations. Screening for presence of annual meeting and relevance to student and resident education yielded 14 organizations. Bylaws/web-domains were reviewed for information related to the annual meeting, leadership opportunities, membership, grants, and travel scholarships. If available, previrtual/in-person and virtual meeting prices were collected. Lastly, discrepancies between webpage information and phone/email correspondence were noted. Results: All (100%) organizations welcomed students at annual meetings. Eleven promoted student presentation/submission. Average student registration fee was $109.3 ± SD$136.5 compared with $181.20 ± SD$157.20 for residents. Of organizations providing previrtual and virtual pricing (n = 10, 71.4%), there was an average price reduction in student registration of $92 (range: $0-375). Average student membership was $31.70/year ± SD $45.50 compared with $38.80 per year ± SD $65.90 for residents. The percentages of organizations offering student research grants, travel scholarships, and national student leadership were 21.4% (n = 3), 35.8% (n = 5), and 28.6% (n = 4) respectively. No organizations had student chapters/committees. All organizations (100%) contained at least one discrepancy between webpage/bylaw and email/phone. Conclusions: Our results suggest that although national opportunities seem to be limited, a role exists for further engagement, with interested students eager to take the initiative. Virtual conferences present a lower-cost alternative for students and residents.
RESUMO
Background: Abdominal panniculectomy after weight loss is a commonly performed procedure with high patient satisfaction yet continues to have a high post-operative complication profile. Several risk-reducing surgical approaches, such as preservation of Scarpa's fascia, use of tissue adhesives, and progressive tension suture techniques have been described. However, the use of tranexamic acid (TXA) has not been previously reported in panniculectomy surgery. Objectives: To improve the safety and predictability of this procedure, the authors investigate whether the use of topically administered TXA during panniculectomy surgery reduces seroma, hematoma, and drain duration. Methods: Consecutive patients who underwent panniculectomy (January 2010 to January 2022) were retrospectively reviewed. Outcome measures included hematoma requiring surgical evacuation, seroma requiring percutaneous aspiration, and drain duration. Patients with thromboembolic diseases and those taking anticoagulation/antiplatelet medications were excluded. Patients who had received TXA were compared with a historical control group who had not received TXA. Results: A total of 288 consecutive patients were included. Topical TXA was administered in 56 (19.4%) cases. The mean (standard deviation [SD]) follow-up was 43.9 (37.4) months (3.7 years). The median (range) resection weight was 2.6 kg (0.15-19.96 kg). Regarding seroma and hematoma formation, the use of TXA did not reduce the likelihood of developing seroma or hematoma (odds ratio [OR] = 1.7, 95% CI [0.56- 4.8], P = 0.38 and OR = 2.1, 95% CI [0.4-11.8], P = 0.42), respectively. The mean (SD) duration of drains was slightly lower in the TXA group (18.1 [12.1] days vs 19.8 [13.9] days); however, this difference was not statistically significant, albeit clinically significant. Conclusions: As the use of TXA in plastic surgical procedures continues to expand, the utility of TXA in panniculectomy and abdominoplasty has not been elucidated. Although previous studies report hematoma and seroma risk reduction, the use of TXA was not associated with a statistically significant reduction in seroma, hematoma, or drain duration following panniculectomy surgery. Prospective, randomized controlled studies on the use of TXA in body contouring are needed.
RESUMO
BACKGROUND: Tranexamic acid (TXA) has gained increasing recognition as a valuable pharmacologic agent within plastic surgery. OBJECTIVES: The aim of this study was to investigate the value and safety profile of both intravenous and topically administered TXA in the setting of bilateral reduction mammaplasty. METHODS: A retrospective review was performed to identify consecutive patients who underwent bilateral reduction mammaplasty for symptomatic macromastia (January 2016-July 2021). Pertinent preoperative, intraoperative, and postoperative details were collected/reviewed. Primary outcome measures included hematoma requiring surgical evacuation and clinically significant/symptomatic seroma formation mandating percutaneous aspiration. Patients taking anticoagulation/antiplatelet medication or those with a history of thromboembolic diseases were excluded. Patients who had received TXA were compared to a historical control group who did not receive TXA within the same consecutive cohort. RESULTS: A total of 385 consecutive patients (770 breasts) were included. TXA was used in 514 (66.8%) cases (topical, 318 [61.9%]; intravenous, 170 [33.1%]; intravenous and topical, 26 [5.1%]). Neither seroma nor hematoma were impacted/reduced with TXA (P > 0.05). Increased age (hazards ratio, 1.06 per 1-year increase; 95% CI, 1.004-1.118) significantly increased the risk of hematoma (P = 0.032). The use of drains significantly decreased the risk of seroma (P < 0.0001). Increased BMI increased the risk of seroma (hazards ratio, 1.16 per 1-kg/m2 increase; 95% CI, 1.06-1.26; P = 0.0013). The use of TXA did not impact drain duration. CONCLUSIONS: This study, the largest to date on the use of IV and topical TXA, did not find any reduction in risk when using TXA in breast reduction surgery.

The aim of this study is to report our institution's experience with pediatric skin malignancies. A single institution retrospective review of pediatric patients with a primary skin malignancy from 1992 to 2020 was performed. Demographics, tumor characteristics and treatment outcomes were reviewed. Ninety-nine patients with 109 primary malignant skin lesions were reviewed. The most common lesion was malignant melanoma [MM] (n = 50, 45.9%). Compared to non-melanoma skin cancer (NMSC), MM were more likely to present on trunk or extremities (p=.01, OR = 3.2), and be misdiagnosed (p=.03, OR = 2.7). NMSC were more common in the head and neck region (p=.01, OR = 3.2), and were associated with a personal history of skin cancer (p=.0005, OR = 17.1) or a known risk factor (p=.04, OR = 2.5). Patients with MM were 12.4-times more likely to develop metastatic disease compared to NMSC (p<.0001). Increased Breslow's thickness also increased the odds of developing metastatic disease (p=.03, OR = 1.6 per 1-mm increase). Interval time between lesion recognition and diagnostic biopsy or surgical treatment did not impact overall survival. Malignant melanoma was the most common malignancy in our cohort, followed by basal cell carcinoma. Malignant melanoma was the most likely tumor to be misdiagnosed and/or metastasize. Treatment delays did not impact risk of metastasis, recurrence or survival rate, though some patients succumbed to disease. These results may be attributed to small sample size or the biology of melanoma in pediatric patients. Awareness of skin malignancies in the pediatric population is imperative to providers and the public, with low threshold for specialty consultation and excision when warranted.

BACKGROUND: Nipple-areolar complex (NAC) tattooing remains a simple and safe procedure, which complements breast reconstruction. This study reviews 11 years of NAC tattooing to identify risk factors for tattoo-related complications. METHODS: Patients undergoing NAC tattooing from January 2009 to March 2020 were reviewed. Patient information, reconstructive, and tattoo procedural details were analyzed. Tattoo-related breast infections, defined as breast redness requiring antibiotic therapy within 30 days after tattoo, were captured. Patients with reactive breast redness during the first 2 postprocedural days were excluded. RESULTS: Overall, 539 patients (949 breasts) were included. Implant-based reconstruction (IBR) was performed in 73.6% of breasts (n = 698), whereas 26.4% (n = 251) underwent autologous-based reconstruction (ABR). Acellular-dermal matrix was used in 547 breasts (57.6%). There as a 13.7% (n = 130) of breasts that underwent pretattoo radiation. There was a 65.3% (n = 456) of breasts that underwent subpectoral IBR, whereas 34.7% (n = 242) breasts underwent prepectoral IBR. Tattoo-related infection rate was 2.2% (n = 21 breasts). Mean time to infection was 6.5 ± 5.3 days. There was a 85.7% (n = 18) of infections that occurred in IBR patients, one third occurring in radiated patients. There was a 95.2% (n = 20) of infections that were treated with oral antibiotics only. One explantation was performed after failed intravenous antibiotics. On multivariable analysis, radiation history (odds ratio, 4.1, P = 0.007) and prepectoral IBR (odds ratio, 2.8, P = 0.036) were independent predictors of tattoo-related infection. Among irradiated breasts, breasts with IBR had greater odds of developing tattoo-related infection versus breasts with ABR (P = 0.025). CONCLUSIONS: Although tattoo-related infections were uncommon, previous radiation and prepectoral IBR were both found to be independent predictors of tattoo-related breast infection. There is a role for preprocedural prophylactic antibiotics in these patients to mitigate infectious risk.

BACKGROUND: Tranexamic acid (TXA) has gained increasing recognition in plastic surgery as a dependable adjunct capable of minimizing blood loss, ecchymosis, and edema. To date, there have been limited data on the utilization of TXA to mitigate liposuction donor site ecchymosis. OBJECTIVES: The authors sought to investigate whether infiltration of TXA into liposuction donor sites safely reduces postoperative ecchymosis. METHODS: A single-surgeon retrospective cohort study was performed to analyze patients undergoing autologous fat transfer for breast reconstruction between 2016 and 2019. Following lipoaspiration, patients in the intervention group received 75 mL of TXA (3 g in NaCl 0.9%) infiltrated into the liposuction donor sites, whereas the historical controls did not. Patient demographics, degree of ecchymosis, surgical complications, and thromboembolic events were examined. A blinded assessment of postoperative photographs of the donor sites was performed. RESULTS: Overall, 120 autologous fat grafting procedures were reviewed. Sixty patients received TXA, whereas 60 patients did not. Patient demographics and comorbidities were similar among the groups. No difference existed between groups regarding donor site locations, tumescent volume, lipoaspirate volume, or time to postoperative photograph. Ten blinded evaluators completed the assessment. The median bruising score of patients who received TXA was significantly lower than that of patients who did not (1.6/10 vs 2.3/10, Pâ =â 0.01). Postoperative complications were similar among the groups. Adverse effects of TXA were not observed. CONCLUSIONS: Patients who received local infiltration of TXA into the liposuction donor sites were found to have less donor site ecchymosis than patients who did not. Further prospective randomized studies are warranted.

BACKGROUND: There has been increasing interest in the superficial circumflex iliac artery perforator (SCIP) flap as a source of thin, pliable soft tissue combined with a favorable donor site. Despite several clinical series from Asia, barriers to adoption include reluctance to perform submillimeter "supermicrosurgery" and the effect of body habitus on flap feasibility. The purpose of this study is to distinguish vascular anatomic characteristics of the SCIP flap in a North American population. METHODS: Computed tomography angiography was examined in 84 flaps in healthy prospective renal donor patients from a radiographic database. Descriptive statistics as well as linear regression comparing variables to body mass index (BMI) were performed. RESULTS: Mean BMI was 27.1 ± 3.5 kg/m2, while the mean patient age was 47.8 ± 11.4 years. The superficial circumflex iliac artery (SCIA) originated from the common femoral artery in 92% cases, with remainder originating from the profunda femoris. The mean vessel diameter was 1.85 mm at source vessel origin. Distance from skin to source vessel averaged 30.7 mm. Suprascarpal subcutaneous thickness averaged 16.5 mm. The mean distance from Scarpa's fascia to vessel origin was 14.1 mm. Direct three-dimensional distance from vessel origin to pubic tubercle was 50.2 mm. A medial and lateral perforator split off of the SCIA was observed in 38 cases (45%). Significant differences were shown when comparing BMI to skin to source vessel distance (p < 0.001), suprascarpal subcutaneous fat thickness (p < 0.001), and fascial distance to vessel origin (p < 0.001). BMI did not significantly affect vessel diameter. CONCLUSION: Despite a significantly higher BMI than many previously published cohorts, the SCIP remains an excellent source of thin and pliable tissue. When dissected closer to the source vessel, a vessel caliber of nearly 2 mm can be achieved, which may obviate the need for "supermicrosurgery" in this population.

BACKGROUND: Antifibrinolytic medications, such as tranexamic acid, have recently garnered increased attention. Despite its ability to mitigate intraoperative blood loss and need for blood transfusion, there remains a paucity of research in breast reconstruction. The authors investigate whether intravenous tranexamic acid safely reduces the risk of hematoma following implant-based breast reconstruction. METHODS: A single-center retrospective cohort study was performed to analyze all consecutive patients undergoing immediate two-stage implant-based breast reconstruction following mastectomy between 2015 and 2016. The incidence of postoperative hematomas and thromboembolic events among all patients was reviewed. The patients in the intervention group received 1000 mg of intravenous tranexamic acid before mastectomy incision and 1000 mg at the conclusion of the procedure. Fisher's exact test and the Mann-Whitney-Wilcoxon test were used. Multivariate logistic regression models were performed to study the impact of intravenous tranexamic acid after adjusting for possible confounders. RESULTS: A total of 868 consecutive breast reconstructions (499 women) were reviewed. Overall, 116 patients (217 breasts) received intravenous tranexamic acid, whereas 383 patients (651 breasts) did not. Patient characteristics and comorbidities were similar between the two the groups. Patients who received tranexamic acid were less likely to develop hematomas [n = 1 (0.46 percent)] than patients who did not [n = 19 (2.9 percent)] after controlling for age, hypertension, and type of reconstruction (prepectoral and subpectoral) (p = 0.018). Adverse effects of intravenous tranexamic acid, including thromboembolic phenomena were not observed. Multivariate analysis demonstrated that age and hypertension independently increase risk for hematoma. CONCLUSIONS: Intravenous tranexamic acid safely reduces risk of hematoma in implant-based breast reconstruction. Further prospective randomized studies are warranted to further corroborate these findings. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BACKGROUND: The tumescent face lift uses the concept of subcutaneous cannula lipodissection of the neck, as opposed to wide skin undermining. Lipodissection mobilizes soft tissue while preserving perforating neurovascular branches. The purpose of this study is two-fold: (1) to compare the skin recruitment with subcutaneous lipodissection of the neck alone versus wide undermining and (2) to examine the effect of superiorly oriented superficial musculoaponeurotic system (SMAS) movement on jowl excursion in the tumescent face lift. METHODS: A cadaveric study was performed on five fresh tissue cadavers. Postauricular skin excursion was measured following subcutaneous lipodissection and then measured again after traditional, wide undermining of the neck skin. Jowl excursion (in reference to the mandibular border) was measured following superiorly oriented SMAS excursion. An electronic force gauge was used to measure force application during measurements. RESULTS: Cannula lipodissection resulted in a mean skin excursion of 41.9 mm. There was no significant difference in skin excursion compared to wide undermining (41.9 mm versus 42.1 mm; p = 0.785). Jowl position, in reference to the mandibular border, moved superiorly by a mean distance of 18.3 mm with vertical SMAS excursion. CONCLUSIONS: Subcutaneous cannula lipodissection results in equivalent skin recruitment in comparison to wide undermining of the neck. A superior vector of pull on the SMAS results in vertical excursion of the jowl in reference to the mandibular border.

BACKGROUND: The need for preoperative imaging as well as anastomotic technique (ie, end-to-side [ETS] vs end-to-end [ETE]) are areas of controversy in microsurgical lower-extremity reconstruction. The objective of this study was to (1) investigate whether preoperative imaging is mandatory and (2) to elicit if the type of anastomosis impacts clinical outcomes. METHODS: A retrospective review of all patients who underwent microvascular lower-extremity reconstruction between 2007 and 2015 by a single surgeon was performed. Patients were categorized into groups based on anastomotic technique, that is, ETE versus ETS anastomosis. Patients in the ETE group were further subclassified into those who had preoperative imaging (computed tomography angiography [CTA]+) versus those who did not (CTA-). Parameters of interest included flap type, thrombosis rate, flap loss, length of stay (LOS), return to ambulation, and rate of secondary amputation. Two-sided statistical analysis was performed using Kruskal-Wallis rank-sum test and Fisher exact test. RESULTS: One hundred twenty-eight patients were analyzed: ETE (n = 40) and ETS (n = 88). Mean follow-up for both groups was 20 ± 19 months. Anterolateral thigh flaps were most commonly performed (71%). Overall flap loss rate was 3.1% without any significant differences noted with respect to thrombosis (arterial, P = 0.09; venous, P = 0.56), flap loss (P = 0.33), LOS (P = 0.28), amputation (P = 1.00), or return to ambulation (P = 0.77). Furthermore, the availability of preoperative imaging (CTA+: N = 11 vs CTA-: N = 29) did not impact rates of thrombosis (arterial, P = 0.29; venous, P = 0.31), flap loss (P = 1.00), LOS (P = 0.26), or return to mobility (P = 0.62). CONCLUSIONS: In light of similar reconstructive outcomes, we prefer to preserve distal extremity perfusion via ETS anastomoses whenever possible. Furthermore, preoperative vascular imaging angiography might not be necessary in patients with palpable pedal pulses on preoperative examination. An actionable algorithm for determining ETS versus ETE anastomosis in lower-extremity reconstruction is presented.

INTRODUCTION: Hemipelvectomy procedures result in massive soft tissue defects. The standard approach is to reconstruct the defect with anterior or posterior hemipelvectomy flaps. Certain situations preclude the use of local tissue flaps, and an alternative is the use of leg fillet flaps, circumferential pedicled or free flaps harvested from the amputated part. The purpose of this study is to present our institution's experience with using pedicled and free fillet flaps to reconstruct hemipelvectomy soft tissue defects. METHODS: We performed a retrospective chart review of patients who underwent hemipelvectomy and fillet flap reconstruction from 2001 to 2018. Demographics, clinical and surgical characteristics, postoperative outcomes, and complications of patients were reviewed. RESULTS: Ten patients were identified and included. Their mean age was 51 ± SD 12.4 years. Six patients underwent standard external hemipelvectomy and 4 patients underwent extended external hemipelvectomy. Seven lower extremity fillet flaps were performed as free tissue transfers, and 3 were pedicled flaps. The mean flap size was 1,153 ± SD 1137 cm2. The mean follow-up was 5 months (range: 1-24 months). Five patients developed postoperative complications; none of them required operative intervention. There were no partial or total flap losses postoperatively. CONCLUSION: Reconstruction with pedicled or free lower extremity fillet flaps is a valuable reconstructive approach, for managing large soft tissue defects following hemipelvectomy when the standard anterior and posterior thigh flaps are unavailable or inadequate for complete soft tissue coverage. This useful technique mitigates donor site morbidity, while simultaneously achieving massive soft tissue coverage with an acceptable complication profile.

BACKGROUND: Prophylactic mesh placement (PMP) at the time of open abdominal surgery has gained momentum over the last decade. However, there remains an identifiable gap in the literature regarding patient-reported outcomes and qualitative metrics. In effort to gauge the population's understanding or familiarity with PMP, this study provides an educational framework and uses crowdsourcing as a novel means to assess perception among the general population. METHODS: A cross-sectional survey study was conducted among the general public to elicit perspectives on PMP. An online crowdsourcing platform was used to capture responses to a questionnaire. Pearson's correlation coefficients, paired t-test, chi-square test, and Fisher's exact tests were performed. RESULTS: Of 433 respondents, 338 (78.1%) were included. Individuals who had previously undergone surgery and those who had prior hernia repair were more likely to choose PMP than surgically naïve patients (P = 0.06). CONCLUSIONS: The majority of respondents support the use of PMP. This study contributes to the existing body of literature on PMP and serves as the first qualitative description to gauge the population's perception and understanding of this surgical technique. Within the evolving health care landscape, understanding quality-of-life measures have become increasingly important in defining successful surgical outcomes. Although the data-driven level-I evidence supports the clinical use of PMP, this study intends to establish a framework for future patient-reported outcome studies.

The purpose of this study was to assess the feasibility of acoustic radiation force impulse shear wave velocity and textural features for characterizing abdominal wall musculature and to identify subject-related and technique-related factors that can potentially affect measurements. Median shear wave velocity measurements for the right external abdominal oblique were the same (1.89 ± 0.16 m/s) for both the active group (healthy volunteers with active lifestyles) and the control group (age and body mass index-matched volunteers from an ongoing hernia study). When corrected for thickness, the ratio of right external abdominal oblique shear wave velocity -to-muscle thickness was significantly higher in the control group than in the active volunteers (4.33 s-1 versus 2.88 s-1; p value 0.006). From the textural features studied for right external abdominal oblique, 8 features were found to be statistically different between the active and control groups. In conclusion, shear wave velocity is a feasible and reliable technique to evaluate the stiffness of the abdominal wall musculature. Sonographic texture features add additional characterization of abdominal wall musculature.

Rhinoplasty is considered one of the most challenging procedures in plastic surgery. The authors introduce a novel concept of translating three-dimensional photographic images into three-dimensionally-printed, patient-specific, life-size models that can be used in preoperative counseling or as an intraoperative reference during rhinoplasty. This article describes the authors' experience with this new application for three-dimensional printing, a technology that is overall garnering more widespread use and has prospective clinical and research applications in aesthetic surgery.

With the expanding horizon of microsurgical techniques, novel treatment strategies for lymphatic abnormalities are increasingly reported. Described in this article is the first reported use of lymphovenous anastomosis surgery to manage recalcitrant chylothoraces in infants. Chylothorax is an increasingly common postoperative complication after pediatric cardiac surgery, with a reported incidence of up to 9.2 percent in infants. Although conservative nutritional therapy has a reported 70 percent success rate in this patient population, failed conservative management leading to persistent chylothorax is associated with a significant risk of multisystem complications and mortality. Once conservative medical strategies are deemed unsuccessful, surgical or radiologic interventions, such as percutaneous thoracic duct embolization or ligation, are often attempted. However, these procedures lack high-level evidence in the infant population and remain a challenge, given the small size of the lymphatic vessels. As such, we report our experience with performing lymphovenous anastomoses in two infants who had developed refractory chylothoraces secondary to thoracic duct injury following cardiac surgery for congenital cardiac anomalies. In addition, this article reviews the relevant pathophysiology of chylothoraces, current treatment algorithm following failed conservative management, and potential role of the microsurgeon in the multidisciplinary management of this life-threatening problem. As part of the evolving microsurgery frontier, physiologic operations, such as lymphovenous anastomosis, may have a considerable role in the management of refractory pediatric chylothoraces. In our experience, lymphovenous anastomosis can restore normal lymphatic circulation within 1 to 2 weeks, liberate patients from mechanical ventilation, and enable expeditious return to enteral feeding.

BACKGROUND: The authors hypothesize that posterior sheath reconstruction to achieve retromuscular mesh placement provides outcomes comparable to traditional retromuscular mesh placement and superior to intraperitoneal repair. METHODS: Patients were divided into three groups: (1) retromuscular mesh placement with repaired posterior sheath defects, (2) retromuscular repair with an intact posterior sheath, and (3) intraperitoneal repair. Primary outcomes included recurrence, surgical-site occurrences, and cost. RESULTS: Overall, 179 patients were included. Posterior sheath defects were repaired primarily with absorbable suture or biological mesh. Recurrence rates differed significantly between standard retromuscular repair and intraperitoneal repair groups (p < 0.009), trended toward significance between repaired posterior sheath and intraperitoneal repair groups (p < 0.058), and showed no difference between repaired posterior sheath and standard retromuscular repair (p < 0.608). Retromuscular repair was clinically protective and cost-effective. CONCLUSIONS: This analysis of posterior sheath reconstruction suggests outcomes comparable to traditional retromuscular repair and a trend toward superiority compared with intraperitoneal repair. Achieving retromuscular closure appears to demonstrate clinical and cost efficacy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BACKGROUND: The establishment of an effective clinical and academic culture within an institution is a multifactorial process. This process is cultivated by dynamic elements such as recruitment of an accomplished and diverse faculty, patient geographic outreach, clinical outcomes research, and fundamental support from all levels of an institution. This study reviews the academic evolution of a single academic plastic surgery practice, and summarizes a 10-year experience of microsurgical development, clinical outcomes, and academic productivity. METHODS: A 10-year retrospective institutional review was performed from fiscal years 2006 to 2016. Microsurgical flap type and operative volume were measured across all microsurgery faculty and participating hospitals. Microvascular compromise and flap salvage rates were noted for the six highest volume surgeons. Univariate and multivariable predictors of flap salvage were determined. RESULTS: The 5000th flap was performed in December of 2015 within this institutional study period. Looking at the six highest volume surgeons, free flaps were examined for microvascular compromise, with an institutional mean take-back rate of 1.53 percent and flap loss rate of 0.55 percent across all participating hospitals. Overall, 74.4 percent of cases were breast flaps, and the remaining cases were extremity and head and neck flaps. CONCLUSIONS: Focused faculty and trainee recruitment has resulted in an academically and clinically productive practice. Collaboration among faculty, staff, and residents contributes to continual learning, innovation, and quality patient care. This established framework, constructed based on experience, offers a workable and reproducible model for other academic plastic surgery institutions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: An untoward outcome following breast reconstruction is diminished or complete loss of sensation. As the reconstructive paradigm continues to evolve, sensory restoration following reconstruction remains a research focus. Despite the multitude of published outcomes, there is marked heterogeneity across studies, thus confounding published outcomes. This study critically appraises the literature to summarize outcomes and establish a framework to guide clinical practice and future research. METHODS: A literature review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in an effort to perform a meta-analysis. The Ovid MEDLINE, PubMed, Embase, Scopus, Cochrane, and ClinicalTrials.gov online databases were queried to capture all publications between 1990 and 2017 that investigated postreconstruction breast sensation. The primary outcome of interest was breast sensation following both implant-based and autologous reconstruction with or without neurotization. Secondary outcomes of interest included time to sensory testing and patient-reported outcomes. RESULTS: Overall, 503 titles were screened, from which 37 articles were ultimately included for analysis, accounting for 1299 patients. There was major methodologic variability and inconsistent measurable outcomes across studies. It can be deduced that postoperative sensation returns spontaneously and unpredictably, neurotization enhances the magnitude and rapidity of sensory restoration when compared to nonneurotized reconstruction, and a sensate reconstruction improves patient-reported outcomes. CONCLUSIONS: Significant study design discrepancies exist, making it difficult to combine data and assess results. To effectively study breast sensation and the impact of neurotization, future investigation will depend on standardizing the way in which breast sensation is measured.

The landscape of gender dysphoria has changed dramatically in recent years secondary to increased societal acceptance, legislative changes, and medical providers' increased awareness of the associated psychosocial burden associated with the diagnosis. National and global advocacy efforts, in conjunction with expanded third-party insurance coverage, have resulted in new health care opportunities for patients suffering from gender dysphoria. Delivering quality, streamlined health care to these patients requires a complex multidisciplinary approach, involving multiple medical and mental health disciplines, including plastic surgeons. To accommodate the expanding demand for gender-affirmation surgery, academic medical centers specializing in these procedures are gradually emerging. Advancing surgical techniques in the setting of rising patient demand encourage plastic surgeons to increasingly provide high-quality health care to this diverse patient population in an effort to optimize psychosocial functioning and minimize the burden of gender dysphoria. Although the current literature is replete with the evolving surgical and technical approaches to gender-affirming surgery, there remain critical gaps in the plastic surgery literature describing the delivery of comprehensive care to these patients. To address these gaps, the authors establish a framework that plastic surgeons can use to guide their management of patients with gender dysphoria to optimize surgical and psychosocial outcomes. First, the authors describe a timeline of events that have shaped present-day transgender medicine and characterize the current role of the plastic surgeon in the management of gender dysphoria. Subsequently, the authors discuss psychosocial and ethical considerations surrounding gender dysphoria. Finally, the authors discuss the future scope of transgender medicine.
