The worldwide outbreak of coronavirus disease 2019 (COVID-19) has forced healthcare systems across the United States to undertake broad restructuring to address the ongoing crisis. The framework of crisis management can assist plastic surgeons navigate the dynamic environment of the COVID-19 pandemic. This manuscript outlines crisis management tools at a number of different levels, from hospital-wide to plastic surgeon-specific, and it offers a practical discussion of the coronavirus situation as it affects plastic surgeons. While there are innumerable ways that this virus is currently changing plastic surgeons' practices, it is crucial to remember that these changes are temporary, and they will be best met by being confronted head-on.

BACKGROUND: Given the relatively small size of thigh-based flaps and the possible necessity for a multiflap reconstruction, it is imperative to arrive at an accurate estimation of flap weight during preoperative planning. It was our objective to develop a novel technique for the preoperative estimation of profunda artery perforator (PAP) flap weight. METHODS: All patients that underwent transverse PAP flap breast reconstruction at two institutions were retrospectively reviewed. Subcutaneous tissue thicknesses were measured on axial computed tomography angiography scans at several predetermined points. The distance from the inferior gluteal crease to the PAP was also recorded. Linear regression was used to estimate flap weight. RESULTS:has a value of 1 if the patient was scanned in the supine position or 0 if prone. The aforementioned formula yielded a median estimated flap weight of 305 g (IQR: 234-402) and a median percent error of 10.5% (IQR: 6.1-16.2). CONCLUSION/CONCLUSIONS: The authors demonstrate a simple and accurate formula for the preoperative estimation of transverse PAP flap weight for breast reconstruction.

Chronic venous insufficiency (CVI) stems from venous hypertension, extravasation of blood, and iron-rich skin deposits. The latter is central to ulcer development through generating reactive oxygen species (ROS) that drive persistent local inflammation and the development of lipodermatosclerosis. The ability to study CVI cutaneous inflammation is fundamental to advancing therapies. To address this end, a novel protocol was adapted to investigate cutaneous wound healing in iron-induced inflammation.

PURPOSE/OBJECTIVE:This study sought to estimate patient-reported outcomes and compare quality-of-life (QOL) measures between patients electing for either open reduction internal fixation (ORIF) or closed reduction with intermaxillary fixation (CRIMF). PATIENTS AND METHODS/METHODS:This was a retrospective cohort study of patients with unilateral condyle fractures who had undergone either ORIF or CRIMF at the New York University Tisch Hospital and Bellevue Hospital Center. The primary study predictor was treatment choice (ORIF or CRIMF). Other study predictors were patient age, gender, and the presence of any other coexisting facial fractures. The 9 study outcomes were derived from an 11-item postoperative QOL questionnaire evaluating self-reported perceptions of pain and function. Univariate comparisons and multivariate regression models were calculated. RESULTS:A total of 38 patients (21 CRIMF and 17 ORIF) comprised the study sample. All patients were eligible for either ORIF or CRIMF, and the choice of treatment was decided through shared decision making after a comprehensive discussion of risks and benefits. With respect to pain outcomes, patients who underwent ORIF reported lower overall pain scores at 2 weeks (P < .01) and 2 months (P = .01), less mastication pain at 3 months (P = .01), and a lower rate of persistent headaches after 6 weeks (P = .04). With respect to functional outcomes, patients who underwent ORIF reported better range of motion at 3 months (P = .01), less treatment-related weight loss (P = .01), and more ease when performing physical (P < .01) and work-related (P < .01) activities. In the multivariate regression models, ORIF was independently associated with decreased pain at 2 weeks (P < .01) and decreased difficulty in obtaining nutrition (P < .01), performing physical activities (P = .02), and performing work-related activities (P < .01). CONCLUSIONS:Patients who underwent ORIF appeared to experience subjective favorable pain and functional QOL outcomes. Given the clinical controversy, the choice of treatment should synthesize patient-reported outcomes and be approached through shared decision making.

BACKGROUND:Skin color matching is an essential factor in achieving optimal aesthetic outcome in partial facial transplantation. However, there is no published literature evaluating the success of color matching to date. Furthermore, a medical professional's perception of an optimal color match may not necessarily translate to that of the general public. The purpose of our study was to evaluate skin color matching between the donor allograft and recipient native tissue in partial facial transplantations to determine the level of success perceived by the general public and medical professionals. METHODS:Published photographs of partial face transplant recipients were used to create a survey where recipient native and donor allograft skin samples were juxtaposed. Thirty-three members of the general public and 30 medical professionals were asked to rate skin color match on a scale from "excellent match" to "not a match." RESULTS:Overall, 47% of given ratings were positive, indicating an "excellent" or "good match," and 53% of ratings were negative, indicating a "poor match" or "lack of match" between the skin sample pairings shown. Of the 19 partial face transplant patients who were rated, 9 patients received >50% positive ratings, and 10 patients received <50% positive ratings. Medical professionals consistently gave more positive ratings, with statistically significant differences in 7 of the 19 rated patients (P < 0.05). CONCLUSION/CONCLUSIONS:The results suggest that there is need for improvement in color matching in partial facial transplantation, and that the general public is more critical of skin color matching compared to medical professionals.

PURPOSE/OBJECTIVE:A hoverboard, or self-balancing scooter, is a battery-powered vehicle with 2 wheels connected by a longboard that requires handsfree operation. The purpose of the present study was to characterize the emergency department visits for hoverboard-related craniomaxillofacial trauma and determine predictors of injuries and hospital admission. MATERIALS AND METHODS/METHODS:and t tests. RESULTS:The final sample included 440 patients, of whom 51% were male and 74% were pediatric (age, ≤18 years). Pediatric and male patients were both less likely to wear helmets (P < .01). The injuries had most commonly occurred in the winter (38%) and in a home setting (77%). Facial fractures were more likely in adults (P = .03) and in the summer (P = .04). The overall admission rate was 4.3%. The admission rates were greater for those with facial fractures (P = .02) and intracranial injuries (P = .03) but lower for those with soft tissue injuries (P < .01). Street injuries resulted in a greater admission rate compared with home injuries (P = .01). CONCLUSIONS:Craniomaxillofacial injuries from hoverboard accidents have resulted in emergency department visits and hospital admissions since the vehicle's introduction to the consumer market in 2015. Most cases occurred in the winter, which might reflect increased sales and novice riders during the holiday season. Injuries to adults, in the summer or outdoors, appear to be more severe. Intracranial injuries were the most frequent diagnosis; thus, helmet wear is recommended.

Background: Transcatheter mitral valve repair with the MitraClip system has been shown to be safe and effective for the treatment of significant primary mitral regurgitation (MR) in patients deemed prohibitive risk for surgery. This analysis evaluated the outcomes of MitraClip repair in primary MR subjects with STS PROM (Society of Thoracic Surgeons Predicted Risk of Mortality) score <6% for surgical repair and <8% for replacement from the global EXPAND (A Contemporary, Prospective Study Evaluating Real-World Experience of Performance and Safety for the Next Generation of MitraClip Devices) study.
Method(s): EXPAND is a prospective, multicenter, international, single-arm study that enrolled subjects at 57 centers in Europe and the United States. All echocardiograms were analyzed by an independent echo core laboratory, and major adverse events were adjudicated by an independent clinical events committee. Study outcomes included MR severity, procedural outcomes, major adverse events, New York Heart Association functional class and KCCQ (Kansas City Cardiomyopathy Questionnaire) score.
Result(s): Four hundred and twenty subjects with primary MR had adequate baseline echocardiographic imaging for assessment by the echo core laboratory. Of the 420 subjects, at least 166 patients either had an STS repair score <6% and an STS replacement score <8%. Average age was 77.2 +/- 10.4 years old, and 54% of the subjects were men. STS PROM score for surgical repair was 2.9 +/- 1.3% and replacement was 4.6 +/- 1.8%. Echo core laboratory-adjudicated acute procedural success, defined as survival to discharge with a successful implant resulting in reduction to MR severity <=2+, was achieved in 93.4% of the subjects. Clinical events committee-adjudicated all-cause mortality rate at 30 days was 1.2% (n = 2), and major adverse events rate was 4.2% (n = 7). MR reduction to <=2+ and MR <=1+ were achieved in 98% and 89% of subjects at 30 days, respectively. The reduction in MR severity was also associated with a significant reduction in left ventricle end-diastolic dimension (52.9 +/- 6.8 mm to 49.9 +/- 7.2 mm; n = 144; p < 0.0001) and volume (126.1 +/- 50.5 ml to 114.5 +/- 44.9 ml; n = 138; p < 0.0001). There were also improvements in functional capacity (69% New York Heart Association functional class III/IV at baseline vs. 18% at 30 days; p < 0.0001) and quality of life (mean change in KCCQ score from baseline to 30 days: +18.7 +/- 24.0; p < 0.0001). Univariate analysis of MR reduction (2 grades or more) were baseline MR severity (p < 0.0001), peak E velocity (p < 0.037), mean mitral gradient (p < 0.026), presence of ruptured chordae (p < 0.001), leaflet flail (p < 0.0002), leaflet billowing (p < 0.0001), and prolapse or flail gap (p < 0.037).
Conclusion(s): In patients with primary MR and an STS repair risk score <6% and replacement score <8%, the MitraClip NTR and XTR system was found to be safe and effective at reducing MR and improving left ventricular remodeling and was associated with significant improvements in quality of life and functional capacity.
