RESUMEN
Expressed on epidermal Langerhans cells, CD1a presents a range of self-lipid antigens found within the skin; however, the extent to which CD1a presents microbial ligands from bacteria colonizing the skin is unclear. Here we identified CD1a-dependent T cell responses to phosphatidylglycerol (PG), a ubiquitous bacterial membrane phospholipid, as well as to lysylPG, a modified PG, present in several Gram-positive bacteria and highly abundant in Staphylococcus aureus. The crystal structure of the CD1a-PG complex showed that the acyl chains were buried within the A'- and F'-pockets of CD1a, while the phosphoglycerol headgroup remained solvent exposed in the F'-portal and was available for T cell receptor contact. Using lysylPG and PG-loaded CD1a tetramers, we identified T cells in peripheral blood and in skin that respond to these lipids in a dose-dependent manner. Tetramer+CD4+ T cell lines secreted type 2 helper T cell cytokines in response to phosphatidylglycerols as well as to co-cultures of CD1a+ dendritic cells and Staphylococcus bacteria. The expansion in patients with atopic dermatitis of CD4+ CD1a-(lysyl)PG tetramer+ T cells suggests a response to lipids made by bacteria associated with atopic dermatitis and provides a link supporting involvement of PG-based lipid-activated T cells in atopic dermatitis pathogenesis.

BACKGROUND: Many factors influence a patient's decision to undergo autologous versus implant-based breast reconstruction, including medical, social, and financial considerations. This study aims to investigate differences in out-of-pocket and total spending for patients undergoing autologous and implant-based breast reconstruction. METHODS: The IBM MarketScan Commercial Databases were queried to extract all patients who underwent inpatient autologous or implant-based breast reconstruction from 2017 to 2021. Financial variables included gross payments to the provider (facility and/or physician) and out-of-pocket costs (total of coinsurance, deductible, and copayments). Univariate regressions assessed differences between autologous and implant-based reconstruction procedures. Mixed-effects linear regression was used to analyze parametric contributions to total gross and out-of-pocket costs. RESULTS: The sample identified 2079 autologous breast reconstruction and 1475 implant-based breast reconstruction episodes. Median out-of-pocket costs were significantly higher for autologous reconstruction than implant-based reconstruction ($597 vs $250, P < 0.001) as were total payments ($63,667 vs $31,472, P < 0.001). Type of insurance plan and region contributed to variable out-of-pocket costs (P < 0.001). Regression analysis revealed that autologous reconstruction contributes significantly to increasing out-of-pocket costs (B = $597, P = 0.025) and increasing total costs (B = $74,507, P = 0.006). CONCLUSION: The US national data demonstrate that autologous breast reconstruction has higher out-of-pocket costs and higher gross payments than implant-based reconstruction. More study is needed to determine the extent to which these financial differences affect patient decision-making.

INTRODUCTION: Disparities in postmastectomy reconstructive care are widely acknowledged. However, there is limited understanding regarding the impact of reconstructive services on cancer recurrence and breast cancer-related mortality. Therefore, this study aims to examine how patient-specific factors and breast reconstruction status influence recurrence-free survival and mortality rates in breast cancer patients. METHODS: Retrospective chart review was performed to collect data on patients who underwent mastectomy at 2 institutions within the New York-Presbyterian system from 1979 to 2019. Sociodemographic information, medical history, and the treatment approach were recorded. Propensity score matching, logistic regression, unpaired t test, and chi-square test were used for statistical analysis. RESULTS: Overall, cancer recurrence occurred in 6.62% (317) of patients, with 16.8% (803) overall mortality rate. For patients who had relapsed disease, completion of the reconstruction sequence was correlated with an earlier detection of cancer recurrence and improved survival odds (P < 0.05). Stratified analysis of the reconstruction group alone showed mortality benefit among patients who underwent free flap procedures (P < 0.05). CONCLUSION: Patients undergoing breast reconstruction after mastectomy are likely to have better access to follow-up care and improved interfacing with the healthcare system. This may increase the speed at which cancer recurrence is detected. This study highlights the need for consistent plastic surgery referral and continued monitoring by all members of the breast cancer care team for cancer recurrence among patients.

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

BACKGROUND: Microsurgical cases are complex plastic surgery procedures with a significant risk of acute postoperative complications. In this study, we use a large-scale database to investigate the temporal progression of complications after microsurgical procedures and the risk imparted by acute postoperative complications on subsequent reconstructive outcomes. METHODS: Microsurgery cases were extracted from the National Surgical Quality Improvement Program database by Current Procedural Terminology codes. Postoperative complications were collected for 30 days after surgery and stratified into four temporal periods (postoperative days [PODs] 0-6, 7-13, 14-20, 21-30). Postoperative complication occurrences were incorporated into a weighted multivariate logistic regression model to identify significant predictors of adverse outcomes (p < 0.05). Separately, a regression model was calculated for the time between index operation and reoperation and additional complications. RESULTS: The final cohort comprised 19,517 patients, 6,140 (31.5%) of which experienced at least one complication in the first 30 days after surgery. The occurrence of prior complications in the postoperative period was a significant predictor of future adverse outcomes following the initial week after surgery (p < 0.001). Upon predictive analysis, overall model performance was highest in PODs 7 to 13 (71.1% accuracy and the area under a receiver operating characteristic curve 0.684); 2,578 (13.2%) patients underwent at least one reoperation within the first 2 weeks after surgery. The indication for reoperation (p < 0.001) and number of days since surgery (p = 0.0038) were significant predictors of future complications after reoperation. CONCLUSION: Prior occurrence of complications in an earlier postoperative week, as well as timing and nature of reoperation, were shown to be significant predictors of future complications.
RESUMEN
PURPOSE: Immediate postmastectomy breast reconstruction plays an integral role in patient care because of its psychosocial benefits. New York State (NYS) passed the 2010 Breast Cancer Provider Discussion Law with the aim of increasing patient awareness of reconstructive options through mandating plastic surgery referral at the time of cancer diagnosis. Short-term analysis of the years surrounding implementation suggests the law increased access to reconstruction, especially for certain minority groups. However, given the continued presence of disparities in access to autologous reconstruction, we aimed to investigate the longitudinal effects of the bill on access to autologous reconstruction along various sociodemographic cohorts. METHODS: Retrospective review identified demographic, socioeconomic, and clinical data for patients undergoing mastectomy with immediate reconstruction at Weill Cornell Medicine and Columbia University Irving Medical Center from 2002 to 2019. Primary outcome was receiving implant or autologous-based reconstruction. Subgroup analysis was based on sociodemographic factors. Multivariate logistic regression identified predictors of autologous reconstruction. Interrupted time series modeling analyzed differences in reconstructive trends for subgroups before and after the 2011 implementation of the NYS law. RESULTS: We included 3178 patients; 2418 (76.1%) and 760 (23.9%) patients underwent implant and autologous-based reconstruction, respectively. Multivariate analysis indicated that race, Hispanic status, and income were not predictors of autologous reconstruction. Interrupted time series showed that with each year leading up to 2011 implementation, patients were 19% less likely to receive autologous-based reconstruction. Following implementation, there was a 34% increase in the odds of receiving autologous-based reconstruction with each passing year. Following implementation, Asian American and Pacific Islander patients experienced a 55% greater increase in the rate of flap reconstruction than White patients. Following implementation, the highest-income quartile experienced a 26% greater increase in the rate of autologous-based reconstruction compared with the lowest-income quartile. After implementation, Hispanic patients experienced a 30% greater decrease in the rate of autologous-based reconstruction compared with non-Hispanic patients. CONCLUSIONS: Our data indicate the long-term efficacy of the NYS Breast Cancer Provider Discussion Law in increasing access to autologous-based reconstruction, especially for certain minority groups. These findings underscore the importance of this bill and encourage its adoption into other states.

ABSTRACT: Various recent developments, including legislation in 2014 banning healthcare discrimination against gender minorities, have contributed to expanding insurance coverage for gender-affirming care, which includes facial gender confirmation surgery (FGCS). Increasing evidence suggests FGCS improves quality-of-life outcomes, but literature evaluating FGCS patient demographics, surgical risk factors, procedures, and complications is limited. Therefore, the authors conducted a study of a national surgical database from 2005 to 2019 attempting to fill in these literature gaps. Statistics were used to assess temporal trends after 2014. A total of 203 FGCS cases were identified, with the earliest occurring in 2013. Case volume increased annually from 2015-2019. The average patient age was 34.0âyears and racial demographics largely mirrored national estimates for the transgender/non-binary population. Obesity (20.7%) and hypertension (3.9%) were the only patient co-morbidities, although a relatively high proportion were underweight (5.4%). The majority of cases were outpatient procedures (66.5%) conducted by either plastic surgery (38.9%) or otolaryngology (61.1%). Comparing FGCSs by anatomic site, the proportion of tracheal procedures decreased between 2015-17 and 2018-19 (25.6% vs. 10.7%, Pâ=â0.0002) whereas the proportion of brow/forehead reconstructions increased (32.6% versus 63.1%, Pâ=â0.0005). These changes coincided with an increase in mean operative time (168.6âminutes versus 260.0, Pâ=â0.0002). Complications were rare (3.9%), and the most common was surgical site infection (3.4%), a previously unreported outcome in the FGCS literature. Overall, FGCS patients are mostly young healthy individuals from diverse racial/ethnic backgrounds, and they have few surgical complications. The increasing volume and complexity of FGCSs may be a result of expanding insurance coverage for previously unaffordable procedures.

BACKGROUND: Poly-4-hydroxybutyric acid (P4HB, Phasix™) is a biosynthetic polymer that degrades by hydrolysis that can be woven into a mesh for use in soft tissue reinforcement. Herein, we describe our initial experience performing complex abdominal wall repair (CAWR) utilizing component separation and P4HB mesh as onlay reinforcement. METHODS: All patients undergoing CAWR between June 2014 and May 2017 were followed prospectively for postoperative outcomes. Only those patients who underwent components separation with primary repair of the fascial edges followed by onlay of P4HB mesh were included in this study. RESULTS: 105 patients (52 male, 53 female; mean age 59.2 years, range 22-84) met inclusion criteria. Mean BMI was 29.1 (range 16-48); 52% patients had prior attempted hernia repair, most with multiple medical comorbidities (71% of patients with ASA 3 or greater). 30% of cases were not clean at the time of repair (CDC class 2 or greater). Median follow-up was 36 months (range 9-63). Eighteen patients (17%) developed a hernia recurrence ranging from 2 to 36 months postoperatively. Five (5%) patients developed a localized superficial infection treated with antibiotics, three (2.8%) required re-operation for non-healing wounds, and six (6%) patients developed seroma. CONCLUSIONS: These data demonstrate a relatively low rate of hernia recurrence, seroma, and other common complications of CAWR in a highly morbid patient population. Importantly, the rate of mesh infection was low and no patients required complete mesh removal, even when placed into a contaminated or infected surgical field.

BACKGROUND: An increasing number of women are choosing to undergo contralateral prophylactic mastectomy with immediate bilateral breast reconstruction. Operating on the contralateral noncancer side is not without its own set of risks. We sought to compare complication rates between the cancerous and contralateral prophylactic breasts. METHODS: A retrospective review was conducted of all patients undergoing immediate postmastectomy bilateral breast reconstruction for unilateral breast cancer between January 2008 and January 2019 at a single institution. Data were collected on patient demographics, cancer and adjuvant/neoadjuvant treatments, tumor, reconstruction, hospital stay, and complications. Complications were compared between the cancerous and the noncancerous breasts. RESULTS: One hundred sixty patients met the inclusion criteria of this study. Of these 160 patients, 33 (20.6%) had complications (major and minor) only to the cancerous breast, 7 (4.4%) had complications only to the noncancerous breast, and 7 (4.4%) had bilateral complications. Most patients underwent tissue expander/implant reconstruction (93.8%) with the rest (6.2%) undergoing abdominally based flap or latissimus dorsi flap reconstruction. Patients with complications were more likely to have hypertension, diabetes, exposure to radiation, and neoadjuvant chemotherapy. Complications included wound dehiscence, hematoma, cellulitis, seroma, capsular contracture, infected implant, and skin necrosis. Overall, there were significantly more complications to the cancerous breasts than the noncancerous breasts (P < 0.001). In addition, although exposure to radiation to the affected side significantly increased the likelihood of complications to that side (P < 0.0001), patients who were not exposed to any radiation were also more likely to have complications to the cancer side than to the noncancer side (P = 0.00065). However, after controlling for the effects of radiation, there was no significant difference in complications between the cancer side and the prophylactic side when stratifying by specific complications. CONCLUSIONS: Although contralateral prophylactic mastectomy with immediate bilateral reconstruction is not without added risk when compared with a unilateral procedure, this study shows that the incidence of complications to the noncancerous breast is less than that to the cancerous breast. This information can be used to help counsel patients with unilateral breast cancer on their treatment options and associated risks.

BACKGROUND: Cosmetic tourism has become increasingly popular despite many associated risks. The economic impact of atypical mycobacterial infections in cosmetic tourism is poorly defined in the literature. We sought to investigate the costs and clinical course of patients with these infections. METHODS: A retrospective review of all patients managed by the Plastic Surgery Division at Columbia University Medical Center from 2013 to 2014 with atypical mycobacterial surgical site infections after cosmetic surgery outside the United States was performed. Data including patient demographics, procedure costs, clinical course, impact on daily life, and costs associated with complications were collected using hospital billing information, patient questionnaires, telephone interviews, and clinical charts. Cost analysis was done to identify the personal and societal costs of these complications. RESULTS: Data from 10 patients were collected and analyzed. Management of mycobacterial infections cost an average of $98,835.09 in medical charges. The indirect cost of these infections was $24,401 with a mean return to work time of 6.7 months. Total patient savings from cosmetic tourism was $3419. The total cost of a mycobacterial infection was greater than $123,236.47. Although the incidence of mycobacterial infection abroad is unknown, the potential cost of an infection alone outweighs the financial benefits of cosmetic tourism if the risk exceeds 2.77%. CONCLUSIONS: Atypical mycobacterial infections as a result of cosmetic tourism come at considerable cost to patients and the health care system. When our results are taken into consideration with other risks of cosmetic tourism, the financial risks likely far outweigh the benefits.

BACKGROUND: Traditional free flap reconstruction of complex intraoral defects often uses large lip-splitting incisions. To reduce morbidity and preserve aesthetics, we have adopted a more technically demanding visor technique obviating an incision through the lower lip through which the resection and reconstruction are performed. METHODS: A retrospective review was performed of patients who underwent free flap reconstruction of intraoral defects over 7 years by a single plastic surgeon (C.H.R.) at a single institution. Patients were included if they underwent a resection from the mandible, tongue, or floor of mouth followed by free tissue transfer as a reconstructive approach. Patients were excluded if they underwent reconstruction of an area that does not traditionally require a lip incision, such as a maxillectomy or laryngeal defect. An ablative approach was taken via a lip-split technique or visor technique. Wound complications, margins of resection, and functional outcomes were assessed. Two standardized questionnaires (Derriford Appearance Scale Short Form and Quality of Life Questionnaire for Head and Neck Cancer) were used to assess psychological distress and dysfunction from disfigurement, speech quality, and oral function. Preoperative and postoperative patient photos were evaluated. RESULTS: Of 27 patients (mean ± SD age, 58.33 ± 13.02 years), 52% (14) had visor reconstructions whereas 48% (13) had lip-splitting reconstructions. About 78.6% of visor patients had widely-free margins compared with 46.2% of the lip-split patients. No differences in surgical-site complications between the lip-split and visor group (38.5% vs 28.6%) or in operative times were observed. Ninety-three percent of visor patients versus 54% of lip-split patients tolerated oral feeds at 1 year. Lip-split patients rated their quality of eating and speech worse than the visor patients (Quality of Life Questionnaire for Head and Neck Cancer mean score, 2.2 vs 1.56). Patients and clinical staff deemed visor reconstructions resulted in less visible sequelae. CONCLUSIONS: A visor technique with no lip-split incision for intraoral free flap reconstruction is an oncologically safe technique to consider that may improve cosmetic and functional outcomes for head and neck reconstruction patients.

BACKGROUND: Sterile sternal dehiscence (SSD) and sternal wound infections (SWIs) are two complications of median sternotomy with high rates of morbidity. Sternal wound complications also carry significant economic burden, almost tripling patients' hospital costs and are considered a nonreimbursable "never event" for Medicare. Historically, SDD and SWI have been recognized as discrete entities, but nonetheless continue to be categorized as a singular complication in literature. The purpose of this study was to determine specific patient demographic and perioperative predictors of SSD and SWI. MATERIALS AND METHODS: An institutional review board-approved, retrospective study of 8098 consecutive patients who underwent cardiac surgery at Columbia University Medical Center between January 2008 and December 2013 was conducted. Patients were categorized into three groups: no sternal wound complication, SSD, or SWI. Statistical analysis was performed using univariate and multivariate logistic regression analysis. RESULTS: Of 8098 patients, there were 73 patients (0.9%) with SSD and 40 (0.5%) with SWI who required plastic surgical consultation, debridement, and flap closure. In univariate analysis of SSD, positive predictors (i.e., "risk" factors) were age >42 years, prior surgery this admission, ≥2 arterial conduits, internal mammary artery (IMA) grafting with or without previous IMA grafting, body mass index (BMI) >30 (obese), CHF, diabetes requiring medication, respiratory failure, and unplanned cardiac reoperation; negative predictors (i.e., "protective" factors) were no arterial conduits and extubation within 24 h. In univariate analysis of SWI, positive predictors were IMA grafting with or without previous IMA grafting, postoperative hematocrit urgent/emergent surgical priority, BMI >30 (obese), cardiac ejection fraction <40%, and respiratory failure; negative predictors were no arterial conduits and elective surgical priority. In multivariate regression, BMI >30, diabetes requiring medication, and respiratory failure were determined to be significant positive predictors of SSD, and IMA grafting with or without prior IMA grafting and respiratory failure were significant positive predictors for SWI; no significant negative predictors were identified. CONCLUSIONS: This study found that SSD and SWI have many common significant predictors consistent with findings that increased BMI, use of IMA grafts, poor cardiac reserve, and postoperative respiratory failure confer increased risk of sternal wound complications. Additionally, this study also found that there were predictors unique to each entity supporting that SSD and SWI may be related but are not a singular entity. Recognition and prevention of significant positive and negative predictors of SSD and SWI may be valuable in preoperative counseling, operative planning, and postoperative management. Although sternal wound complications can be successfully managed by plastic surgical intervention, preventing the development of median sternotomy complications may curb costs incurred by both patients and health care systems.

BACKGROUND: Recipient-site infection after oropharyngeal reconstruction is a potentially disastrous complication. Although studies suggest that perioperative antibiotics reduces infection rates in these patients from 87% to 20%, there is no consensus regarding what constitutes the most appropriate antibiotic regimen and duration of treatment. METHODS: A retrospective review of perioperative antibiotic administration was performed of all patients who underwent local, pedicled, or free flap oropharyngeal reconstruction after oncologic resection by a single surgeon at a single institution between 2007 and 2013 to assess for recipient-site complications. RESULTS: Ninety-seven patients underwent 100 reconstructions (61 free flap reconstructions, 39 pedicled/local flap reconstructions) and all received a combination of intravenous (IV) antibiotic agents designed to cover oral flora. There were 23 (23%) recipient-site complications, which included cellulitis (9%), mucocutaneous fistula (5%), abscess (5%), and wound dehiscence (4%). Duration of antibiotic prophylaxis, defined as less than 48 hours (short-course) or greater than 48 hours (long-course), was not a significant predictor of recipient-site complication. Significant risk factors for recipient-site complications were clindamycin prophylaxis (P < 0.008), increased duration of surgery (P < 0.047), and advanced age (P < 0.034). Recipient-site complication was found to be a significant predictor of both increased length of hospital stay (P < 0.001) and increased time to the resumption of enteral feeds (P < 0.035). CONCLUSIONS: These data suggest that extended courses of perioperative antibiotics do not confer additional benefits in patients undergoing oropharyngeal reconstruction. We recommend a limited 48-hour course of prophylactic antibiotics with sufficient aerobic and anaerobic coverage to help minimize the incidence of antibiotic-related morbidities.

BACKGROUND: The superomedial pedicle parenchymal excision pattern for reduction mammaplasty has the benefits of a reproducible breast shape and improved superomedial fullness, but is limited by a susceptibility to nipple retraction. The senior author of this paper has formalized the "superior ledge" modification of the superomedial pedicle technique (SL-SMP) to address these limitations. OBJECTIVE: To describe the technical details of the SL-SMP breast reduction technique and to analyze patient outcomes. METHODS: The technique involves only partial-thickness parenchymal excision superolateral to the pedicle, thereby leaving a "superior ledge" of parenchyma on top of which the nipple-areola complex (NAC) rests in a tension-free manner. Postoperative photographs were recorded; and patient demographics, intraoperative details, complications, and outcomes were recorded and analyzed. RESULTS: One hundred seven patients underwent SL-SMP reduction mammaplasty between 2007 and 2013. Complications included wound-healing complications (9.3 %), infection (2.8 %), seroma (1.9 %), and hematoma (1.9 %). Mean follow-up was 44.6 months (Range: 17-72), and during that period no incidence of clinically relevant NAC retraction was noted by either the patient or surgical team. CONCLUSIONS: Maintenance of a distinct superior ledge underlying the final position of the NAC is an important modification to stress, to prevent nipple retraction. Importantly, the height of the ledge can be personalized for each patient. We feel it is a valuable addition to the plastic surgeon's armamentarium to optimize outcomes for patients seeking relief from excessive breast tissue.

Background Communication, particularly transmission of information between the surgical and nursing teams, has been identified as one of the most crucial determinants of patient outcomes. Nonetheless, transfer of information among and between the physician and nursing teams in the immediate postoperative period is often informal, verbal, and inconsistent. Methods An iterative process of multidisciplinary information gathering was undertaken to create a novel postoperative communication system (the "Pop-form"). Once developed, nurses were surveyed on multiple measures regarding the perceived likelihood that it would improve their ability to provide directed patient care. Data were quantified using a Likert scale (0-10), and statistically analyzed. Results The Pop-form records and transfers operative details, specific anatomic monitoring parameters, and senior physician contact information. Sixty-eight nurses completed surveys. The perceived usefulness of different components of the Pop-form system was as follows: 8.9 for the description of the procedure; 9.3 for the operative diagram; 9.4 for the monitoring details and parameters; and 9.4 for the direct contact information for the appropriate surgical team member. All respondents were in favor of widespread adoption of the Pop-form. Conclusion This uniform, visual communication system requires less than 1 minute to compose, yet formalizes and standardizes inter-team communication, and therefore shows promise for improving outcomes following microvascular free tissue transfer. We believe that this simple, innovative communication tool has the potential to be more broadly applied to many other health care settings.

BACKGROUND: Pulsed electromagnetic fields (PEMF) reduce postoperative pain and narcotic requirements in breast augmentation, reduction, and reconstruction patients. PEMF enhances both calmodulin-dependent nitric oxide and/or cyclic guanosine monophosphate signaling and phosphodiesterase activity, which blocks cyclic guanosine monophosphate. The clinical effect of these competing responses on PEMF dosing is not known. METHODS: Two prospective, nonrandomized, active cohorts of breast reduction patients, with 15 min PEMF per 2 h; "Q2 (active)", and 5 min PEMF per 20 min; "5/20 (active)", dosing regimens were added to a previously reported double-blind clinical study wherein 20 min PEMF per 4 h, "Q4 (active)", dosing significantly accelerated postoperative pain reduction compared with Q4 shams. Postoperative visual analog scale pain scores and narcotic use were compared with results from the previous study. RESULTS: Visual analog scale scores at 24 h were 43% and 35% of pain at 1 h in the Q4 (active) and Q2 (active) cohorts, respectively (P < 0.01). Pain at 24 h in the 5/20 (active) cohort was 87% of pain at 1 h, compared with 74% in the Q4 (sham) cohort (P = 0.451). Concomitantly, narcotic usage in the 5/20 (active) and Q4 (sham) cohorts was not different (P = 0.478), and 2-fold higher than the Q4 (active) and Q2 (active) cohorts (P < 0.02). CONCLUSIONS: This prospective study shows Q4/Q2, but not 5/20 PEMF dosing, accelerated postoperative pain reduction compared with historical shams. The 5/20 (active) regimen increases NO 4-fold faster than the Q4 (active) regimen, possibly accelerating phosphodiesterase inhibition of cyclic guanosine monophosphate sufficiently to block the PEMF effect. This study helps define the dosing limits of clinically useful PEMF signals.

BACKGROUND: Partial hypopharyngeal defects are most commonly reconstructed with the pectoralis major myocutaneous flap (PMMF) or free fasciocutaneous (FFC) flap. The purpose of this study is to determine the ideal method for reconstruction of partial hypopharyngeal defects by reviewing our institutional experience and the literature. METHODS: A retrospective review of partial hypopharyngeal reconstructions since 2009 was performed. A National Library of Medicine search of studies on partial hypopharyngeal reconstruction since 1988 was performed. Data on complications, diet, and speech were extracted and pooled. RESULTS: A total of 18 patients were studied-9 had PMMF reconstruction and 9 had FFC reconstruction. Operative time (8.75 vs. 13.0 hours, p = 0.0003) was shorter in the PMMF group. Pharyngocutaneous fistula developed in one PMMF patient (11.1%) and two FFC patients (22.2%). Late strictures occurred in three PMMF patients. Six patients in each group (66.7%) progressed to a regular diet. Three patients in each group produced tracheoesophageal speech after TEP. Literature review identified 36 relevant studies, with 301 patients reconstructed with PMMF and 605 patients with FFC. Pooled-data analysis revealed that PMMF had higher reported rates of fistula (24.7 vs. 8.9%, p < 0.0001) and requirement for second surgery (11.3 vs. 5.5%, p = 0.04). There was no difference in stricture rates or progression to regular diet. Fewer PMMF patients produced tracheoesophageal speech (17.5 vs. 52.1%, p < 0.0001). CONCLUSIONS: PMMF and FFC flaps are valid approaches to reconstructing partial hypopharyngeal defects, though rates in the literature of fistula, need for revisional surgery, and tracheoesophageal speech after laryngectomy are more favorable after free flap reconstruction.

Use of vasopressors is controversial in patients undergoing free flap reconstruction. Recent literature has suggested that it is safe to administer vasopressors intraoperatively during these procedures. However studies have not addressed whether this safety extends to continuous high dose use. We present two cases of patients who underwent surgery for squamous cell carcinoma of the pharyngeal region, requiring laryngopharyngectomy. Both had pharyngeal reconstruction with a free anterolateral thigh (ALT) flap. The first required intraoperative vasopressors throughout the surgery, extending into the postoperative period. The second required vasopressors in the postoperative period continuously for weeks after surgery. Vasopressors were administered at treatment levels for shock. Neither developed flap compromise, suggesting that pharyngeal reconstruction with an ALT flap may be safely performed in the setting of continuous high-dose vasopressors.

PURPOSE: Resection of the posterior mandible for tumor or osteonecrosis may include the mandibular condyle, an integral part of the temporomandibular joint (TMJ). Condylar reconstruction, including use of prostheses, the native condylar head, or part of the fibula, all have associated drawbacks including skull base erosion and the potential for ankylosis and TMJ dysfunction as well as the increased difficulty associated with trying to recapitulate the TMJ with high fidelity. We report our experience leaving a single side of the reconstructed mandible unsecured to the glenoid fossa, allowing the mandible to "hang." We hypothesized that a good functional recovery may be achieved with this simple approach while avoiding the potential for ankylosis and TMJ dysfunction. METHODS: A retrospective chart review of all patients undergoing free fibula reconstruction of the mandible with condylar removal was performed. Outcomes were determined by maximum interincisal opening, occlusion, and diet after full recovery. RESULTS: Six patients were studied. Two had condylar reconstruction with a contoured fibular head secured to the glenoid fossa. One of them had progressive postoperative trismus and ankylosis. One patient was reconstructed with the native condyle rigidly fixed to the fibula flap, complicated by avascular necrosis requiring condylar resection, with good function afterward. Three patients were left to "hang." All 3 had either normal or improved function after surgery. Two had slight ipsilateral deviation on mouth opening. CONCLUSIONS: Function can reliably be reestablished after segmental mandibulectomy and condylectomy with a vascularized fibula flap whose distal end is not precisely contoured or actively seated in the glenoid fossa, as a valid alternative to condylar reconstruction.

Background: Gender-affirming surgery is becoming more common among reconstructive surgeons. Bibliometric analyses are statistical evaluations of published scientific correspondence and are a validated method of measuring influence in the scientific community. As no such bibliometric analysis has been done as of yet, the purpose of this study is to identify the characteristics of the 50 most-cited peer-reviewed articles on gender-affirming surgery. Methods: The Scopus abstract and citation database was utilized in April 2020 to search for English-language publications related to gender-affirming surgery. The 50 most-cited publications that met inclusion criteria were reviewed for various metric tabulations. Results: The 50 publications have been cited a total of 4402 times. Thirty-one (62%) were published in 2000 or later. Phalloplasty was the most discussed surgical technique, and 18 of the articles focused on female-to-male (FtM) patients. Case series (46%) and review articles (24%) were most common and there were no Level I or Level II studies. The Netherlands contributed the most, with 13 articles. Among the most frequent keywords in the 50 abstracts were "flap" and "complication". The earliest author keywords used were "transsexual" and "sex reassignment". Conclusions: The keyword usage in these abstracts over time seems to follow the trend of a more socially inclusive lexicon. A focus on studies with a higher level of evidence may optimize surgeon education and more appropriately guide clinical practice. This study reveals that the most influential and commonly referenced studies may not be sufficient to appropriately guide clinical practices.
Contexte: La chirurgie d'affirmation du genre devient plus fréquente pour les chirurgiens spécialistes de chirurgie reconstructrice. Les analyses bibliométriques sont des évaluations statistiques de la correspondance scientifique publiée et c'est un moyen de mesure de l'influence dans la communauté scientifique. Considérant qu'une telle analyse bibliométrique n'a pas encore été réalisée, le but de la présente étude est d'identifier les caractéristiques des 50 articles évalués par des pairs le plus souvent cités sur la chirurgie d'affirmation de genre. Méthodes: La base de données de résumés et citations Scopus a été utilisée en avril 2020 pour rechercher des publications en anglais liées à la chirurgie d'affirmation du genre. Les 50 publications les plus citées répondant aux critères d'inclusion ont été analysées pour tabuler différentes mesures. Résultats: Au total, les 50 publications ont été citées 4 402 fois. Trente-et-une (62%) ont été publiées en 2000 ou plus récemment. La phalloplastie a été la technique chirurgicale la plus discutée et 18 de ces articles portaient sur les patients féminins à masculins. Les séries de cas (46%) et les articles de synthèse (24%) étaient les plus fréquents, mais il n'y avait aucune étude de niveau I ou de niveau II. Les Pays-Bas ont le plus contribué avec 13 articles. Parmi les mots-clés les plus fréquents dans les 50 résumés, on trouve « lambeau/volet ¼ (flap) et « complication ¼. Les mots-clés les plus anciens utilisés par les auteurs étaient « transsexuel ¼ et « changement de sexe ¼. Conclusions: L'utilisation de mots clés au fil du temps dans ces résumés semble suivre la tendance d'un lexique plus socialement inclusif. Une focalisation sur des études ayant un plus haut niveau de données probantes peut améliorer la formation des chirurgiens et guider de manière plus adaptée la pratique clinique. Cette étude révèle que les études les plus influentes et le plus souvent référencées peuvent être insuffisantes pour correctement guider les pratiques cliniques.
