AIMS/OBJECTIVE:Reduction mammoplasty (RM) is one of the most common plastic surgeries in the US. We aimed to demonstrate the rate of incidental atypical and malignant breast lesions (AMBL) found in RM specimens and the impact of the number of submitted tissue sections on the rate of ABL. METHODS AND RESULTS/RESULTS:We analyzed our database for patients who underwent reduction mammoplasty between 2000 and 2018. Patients with a history of breast cancer were excluded from the study. All pathology reports were analyzed for AMBL (ALH, LCIS, FEA, ADH, DCIS, invasive carcinoma). The grossing protocol was to submit ten sections from each breast between 2000 and 2013, and six sections between 2014 and 2018. One hundred and sixty-nine of 5208 patients (3.3%) and 216 of 10,340 RM specimens (2.1%) showed at least one AMBL. Nineteen (0.36%) patients had incidental cancer. The median age of patients with AMBL was significantly higher than patients without ABL (59 vs. 45 years old). There was no cancer in patients < 30 years old. The age-controlled rate of overall AMBL as well as atypia and cancer only did not decrease by submitting fewer sections during the 2014-2018 period compared to the 2010-2013 period. CONCLUSION/CONCLUSIONS:Decreasing the number of tissue sections from ten to six did not lead to a significant decrease in the rate of overall AMBL or cancer. Our data suggest that submitting six tissue sections from each breast for patients >30 years old and two sections from each breast for patients < 30 years old would be sufficient.

BACKGROUND:Patients with Crouzon syndrome develop various types of anatomic deformities due to different forms of craniosynostosis, yet they have similar craniofacial characteristics. However, exact homology is not evident. Different pathology then may be best treated by different forms of surgical technique. Therefore, precise classification of Crouzon syndrome, based on individual patterns of cranial suture involvement is needed. METHODS:Ninety-five computed tomography (CT) scans (Crouzon, n = 33; control, n = 62) were included in this study. All the CT scans are divided into 4 types based on premature closure of sutures: class I = coronal and lambdoidal synostosis; class II = sagittal synostosis; class III = pansynostosis; and class IV = "Others." The CT scan anatomy was measured by Materialise software. RESULTS:The class III, pansynostosis, is the most prevalent (63.6%). The classes I, III, and IV of Crouzon have significantly shortened entire anteroposterior cranial base length, with the shortest base length in class III. The external cranial measurements in class I show primarily a decreased posterior facial skeleton, while the class III presented with holistic facial skeleton reduction. Class II has the least severe craniofacial malformations, while class III had the most severe. CONCLUSION/CONCLUSIONS:The morphology of patients with Crouzon syndrome is not identical in both cranial base and facial characteristics, especially when they associated with different subtypes of cranial suture synostosis. The classification of Crouzon syndrome proposed in this study, summarizes the differences among each subgroup of craniosynostosis suture involvement, which, theoretically, may ultimately influence both the timing and type of surgical intervention.

Children with cleft and craniofacial conditions commonly present with concurrent airway anomalies, which often manifest as sleep disordered breathing. Craniofacial surgeons and members of the multidisciplinary team involved in the care of these patients should appreciate and understand the scope of airway pathology as well as the proper means of airway assessment. This review article details the prevalence and assessment of sleep disordered breathing in patients with craniofacial anomalies, with emphasis on indications, limitations, and interpretation of polysomnography.

As the technology for ectogenesis continues to advance, the ethical implications of such developments should be thoroughly and proactively explored. The possibility of full ectogenesis remains hypothetical at present, and myriad concerns regarding the safety and efficacy of the technology must be evaluated and addressed, while pressing moral considerations should be fully deliberated. However, it is conceivable that the technology may become sufficiently well established in the future and that eventually full ectogenesis might be deemed ethically acceptable as a reproductive alternative to gestation within a human womb under certain circumstances. If the safety and efficacy of full ectogenesis are established, if ethical dilemmas are sufficiently well addressed, and if the technology is offered as a reproductive option to cisgender heterosexual individuals or couples desiring to become parents, there is a moral obligation grounded in social justice to ensure that full ectogenesis be made available to individuals or couples identifying as members of sexual- or gender-minority groups who likewise seek to pursue parenthood. We examine the history of access to current family-building options, including assisted reproductive technology, surrogacy and adoption, for these populations and conclude that in the absence of robust empirical evidence suggesting an increased risk of harm to children of individuals and couples who identify as members of sexual- or gender-minority groups, equitable access to ectogenesis as a pathway to parenthood for sexual and gender minorities must be assured as a matter of reproductive justice.

BACKGROUND:Women now constitute 40.5 percent of integrated plastic surgery residents; however, in 2007, women represented only 11.3 percent of the leadership positions in plastic surgery societies and journal editorial boards. The authors analyzed female representation in these societies and editorial boards over the past 10 years. METHODS:Names of board members from the major plastic surgery societies (American Society of Plastic Surgeons, The Plastic Surgery Foundation, and American Society for Aesthetic Plastic Surgery, among others) for the past 10 years and the major plastic journals (Plastic and Reconstructive Surgery, Annals of Plastic Surgery, and so on) from the past 5 years were extracted from their websites. The yearly percentage of female plastic surgery residents was obtained from Accreditation Council for Graduate Medical Education published data. The proportions of women in society leadership, editorial boards, and residency were compared with data analyses of time series trend and linear and Auto Regressive Integrated Moving Average time series modeling. RESULTS:Over the past 10 years, the percentage of female residents has grown steadily, from 21.84 percent to 37.31 percent. Similarly, female representation in society leadership has grown from 6.78 percent to 20.29 percent. Both growth coefficients were statistically significant and showed no statistical difference between the two. In contrast, editorial board leadership over the past 5 years showed statistically insignificant growth and showed a statistically significant difference when compared to the growth of the percentage of female residents and female representation in society leadership. CONCLUSION/CONCLUSIONS:Female representation in plastic surgery society leadership shows promising growth, whereas their representation on editorial boards showed significantly less growth, which may reflect the slower turnover on these boards.

BACKGROUND:Improving the quality of research published in plastic surgery literature has been recognized as a difficult and time-intensive process. Despite significant progress over the last decade, leaders in the field continue to advocate for higher-quality studies to better inform clinical practice. OBJECTIVES/OBJECTIVE:The aim of this study was to evaluate and analyze trends in the levels of evidence (LOEs) of the plastic surgery literature over the last decade in 4 major journals. METHODS:After systematic review of all articles published between 2008 and 2017 in Plastic and Reconstructive Surgery, Annals of Plastic Surgery, Journal of Plastic, Reconstructive, and Aesthetic Surgery, and Aesthetic Surgery Journal (ASJ), included articles were assigned an LOE and classified according to study design and category. RESULTS:In total, 8211 articles were included. Case series and reports represented 36.1% and 13.6% of studies, respectively. Additionally, 27.2% were retrospective cohort studies, 8.2% prospective cohort studies, 3.9% systematic reviews, and 2.9% randomized controlled trials (RCTs). Overall, the percentage of Level I/II studies has increased from 10.9% in 2008 to 17.3% in 2017. ASJ published the greatest proportion of Level I/II studies (23.2%) and RCTs (5.1%) of all the journals. There were significant differences in the distribution of Level I/II studies by journal (P < 0.001) and category (P < 0.001). CONCLUSIONS:Over the past decade, plastic surgery journals have published higher-quality research and a significantly greater proportion of Level I and II studies. The field must continue to strive for robust study designs, while also recognizing the importance of lower-LOE research.

BACKGROUND:Three-dimensionally-printed bioceramic scaffolds composed of β-tricalcium phosphate delivering the osteogenic agent dipyridamole can heal critically sized calvarial defects in skeletally mature translational models. However, this construct has yet to be applied to growing craniofacial models. In this study, the authors implanted three-dimensionally-printed bioceramic/dipyridamole scaffolds in a growing calvaria animal model and evaluated bone growth as a function of geometric scaffold design and dipyridamole concentration. Potential adverse effects on the growing suture were also evaluated. METHODS:Bilateral calvarial defects (10 mm) were created in 5-week-old (approximately 1.1 kg) New Zealand White rabbits (n = 16 analyzed). Three-dimensionally-printed bioceramic scaffolds were constructed in quadrant form composed of varying pore dimensions (220, 330, and 500 μm). Each scaffold was coated with collagen and soaked in varying concentrations of dipyridamole (100, 1000, and 10,000 μM). Controls consisted of empty defects. Animals were killed 8 weeks postoperatively. Calvariae were analyzed using micro-computed tomography, three-dimensional reconstruction, and nondecalcified histologic sectioning. RESULTS:Scaffold-induced bone growth was statistically greater than bone growth in empty defects (p = 0.02). Large scaffold pores, 500 μm, coated in 1000 μM dipyridamole yielded the most bone growth and lowest degree of scaffold presence within the defect. Histology showed vascularized woven and lamellar bone along with initial formation of vascular canals within the scaffold lattice. Micro-computed tomographic and histologic analysis revealed patent calvarial sutures without evidence of ectopic bone formation across all dipyridamole concentrations. CONCLUSION/CONCLUSIONS:The authors present an effective pediatric bone tissue-engineering scaffold design and dipyridamole concentration that is effective in augmentation of calvarial bone generation while preserving cranial suture patency.

INTRODUCTION/BACKGROUND:Digital simulators are potential solutions to challenges facing surgical education. The authors sought to evaluate the reach and utilization of a freely-accessible craniofacial surgery digital educational simulator. More importantly, we compare usage patterns between web-based and mobile-based platforms. METHODS:A 3-way collaboration between academic, non-profit (myFace, New York, NY), and biotechnology (Biodigital, New York, NY) stakeholders in 2015 produced the Craniofacial Interactive Virtual Assistant Pro (CIVA-Pro). CIVA-Pro is a freely-accessible craniofacial surgery digital educational simulator. In addition to the web-based platform, a mobile-based platform was launched in 2017. Usage analytics were collected and analyzed. RESULTS:Since its launch, 751 registered users from 117 countries had accessed CIVA-Pro. The total number of sessions was 9531, including 7500 web and 2031 mobile sessions. The total screen time was 403.9 hours, 290.3 for the web and 113.6 for the mobile platform. Comparison of the mean monthly screen time and number of monthly sessions between platforms since 2017 demonstrated a significantly higher mean monthly screen time (60.1 ± 33.2 versus 29.4 ± 16.5 hours; P = 0.002) and number of sessions (110.2 ± 36.1 versus 58.1 ± 31.9; P < 0.0001) for the mobile-based platform. The mean screen time per session was comparable (P = 0.86). CONCLUSION/CONCLUSIONS:A freely available digital craniofacial surgery educational simulator designed for surgical trainees can achieve significant global reach. Significantly higher utilization of the mobile-based platform of the simulator as compared to the web-based platform reinforces the need to invest in user-friendly, easily accessible, and widely available digital educational resources by key stakeholders to ensure optimal plastic surgery trainee education.
