The Coronavirus Disease 2019 (COVID-19) pandemic has presented a major threat to public health worldwide alongside unprecedented global economic and social implications. In the absence of a "gold standard" treatment, the rapid development of a safe and effective vaccine is considered the most promising way to control the pandemic. In recent years, traditional vaccine technologies have seemed insufficient to provide global protection against the rapid spread of emerging pandemics. Therefore, the establishment of novel approaches that are independent of whole pathogen cultivation, cost-effective, and able to be rapidly developed and produced on a large scale are of paramount importance for global health. This article summarizes the current efforts to develop a COVID-19 vaccine, including the ongoing and future anticipated clinical trials. We also provide plastic and reconstructive surgeons with insight into the novel technologies currently utilized for COVID-19 vaccine development, focusing on the very promising viral-vector-based and gene-based vaccine technologies. Each platform has its own advantages and disadvantages related to its efficacy and ability to induce certain immune responses, manufacturing capacity, and safety for human use. Once the fundamental key challenges have been addressed for viral-vector-based and gene-based vaccines, these novel technologies may become helpful in winning the fight against COVID-19 and transforming the future of health care.
Enhanced recovery after surgery (ERAS) protocols utilize multi-modal approaches to decrease morbidity, narcotic usage, and length of stay. In 2013, we made several changes to our perioperative approach to children undergoing complex craniofacial procedures. The goal of this study was to analyze our protocol for children undergoing fronto-orbital advancement (FOA) for craniosynostosis.

A retrospective chart review was performed after IRB approval, for children who underwent fronto-orbital advancement for craniosynostosis from 2010 to 2018. The ERAS protocol, initiated in December 2013, involves hemoglobin optimization, cell-saver technology, tranexamic acid, specific postoperative fluid titration, and a transfusion algorithm. The analgesic regimen focuses on narcotic reduction through the utilization of scheduled acetaminophen, ibuprofen, or ketorolac, and a dexmedetomidine infusion with opioids only for breakthrough pain.

Fifty-five ERAS protocol children and 23 control children were analyzed. ERAS chilis is a safe and effective multimodal approach to managing complex craniofacial surgical recovery.
Episodes of intracranial hypertension are associated with reductions in cerebral cortical thickness (CT) in syndromic craniosynostosis. Here we focus on Crouzon-Pfeiffer syndrome patients to measure CT and evaluate associations with type of primary cranial vault expansion and synostosis pattern.

Records from 34 Crouzon-Pfeiffer patients were reviewed along with MRI data on CT and intracranial volume to examine associations. Patients were grouped according to initial cranial vault expansion (frontal/occipital). Data were analyzed by multiple linear regression controlled for age and brain volume to determine an association between global/lobar CT and vault expansion type. Synostosis pattern effect sizes on global/lobar CT were calculated as secondary outcomes.

Occipital expansion patients demonstrated 0.02 mm thicker cortex globally (
= 0.81) with regional findings, including thicker cortex in frontal (0.02 mm,
= 0.77), parietal (0.06 mm,
= 0.44) and occipital (0.04 mm,
= 0.54) regions; and thinner cortex in temporal (-0.03 mm,
= 0.69), cingulate (-0.04 mm,
= 0.785), and, insula (-0.09 mm,
= 0.51) regions. Greatest effect sizes were observed between left lambdoid synostosis and the right cingulate (d = -1.00) and right lambdoid synostosis and the left cingulate (
= -1.23). Left and right coronal synostosis yielded effect sizes of
= -0.56 and
= -0.42 on respective frontal lobes.

Both frontal and occipital primary cranial vault expansions correlate to similar regional CT in Crouzon-Pfeiffer patients. Lambdoid synostosis appears to be associated with cortical thinning, particularly in the cingulate gyri.

Artificial intelligence (AI) in healthcare delivery has become an important area of research due to the rapid progression of technology, which has allowed the growth of many processes historically reliant upon human input. AI has become particularly important in plastic surgery in a variety of settings. This article highlights current applications of AI in plastic surgery and discusses future implications. We further detail ethical issues that may arise in the implementation of AI in plastic surgery.

We conducted a systematic literature review of all electronically available publications in the PubMed, Scopus, and Web of Science databases as of February 5, 2020. All returned publications regarding the application of AI in plastic surgery were considered for inclusion.

Of the 89 novel articles returned, 14 satisfied inclusion and exclusion criteria. Articles procured from the references of those of the database search and those pertaining to historical and ethical implications were summarized when releva Such considerations are significant, as high ethical standards are key to appropriate and longstanding implementation of AI.
Diversity within the medical workforce remains a topic of discussion in academia, particularly when it comes to the underrepresentation of certain ethnic groups and gender in the surgical specialties. In this article, we look at how the gender and ethnicity of surgeons at a large academic institution in a rural setting compare with those of the population it serves.

We looked at demographic data from 2008 to 2018 and compared population trends among surgeons and patients.

We found that while whites represent the large majority in both the surgeon and patient populations, absolute number and percentage of whites in the patient population seem to be trending downward from 2008 to 2018, but trending upward among surgeons (attendings and residents). In addition, we found that while Asians make up only 1% of the patient population, they represent the second largest group (17%) among surgeons, with more than twice the proportion percentage of the second largest group within the patient population, composed of Hispanics (6%). Finally, we found a significant gender difference between the 2 populations with almost two-thirds of the surgeons being men, compared with the nearly even split of men and women within the patient population.

Ultimately, understanding how gender and ethnic diversity in the surgical workforce compares with that of the patient population being served may aid in designing training programs to address cultural competency and awareness as well as in impacting administrative decisions and hiring.

As the opioid epidemic continues to yield a national crisis, the incidence and severity of this disease process have increased. Reconstruction of the aortic root is a challenging undertaking and carries the risk of recurrent infection. The omentum has an established reputation as a reliable flap in thoracic reconstruction, given its amorphous form and immunogenic properties, but it has not been utilized for aortic root infections. We present a novel indication for the omental flap using a cardioplastic approach in coverage of aortic root reconstruction. Four patients were treated with pedicled omental flap coverage after aortic root reconstruction. All patients had successful flap healing with no evidence of recurrent infection. This series demonstrates the technical feasibility and clinical utility for providing soft tissue coverage and antimicrobial protection when used in aortic root reconstruction.For craniofacial surgeons, cleft palate repair is an intricate and difficult operation positionally. Historically, use of loupe magnification and a headlight can cause significant strain to the surgeon's neck and, at times, subpar optics for both the operator and the assistant. The use of an operating microscope was first advocated by Sommerlad in 2003. By using the operating microscope for cleft palate closure, there are improved ergonomics for the surgeon and assistant by allowing for straight in-line back and neck posture with excellent visualization of the surgical field for the entire surgical team. The available zoom and focus improve the ability to isolate and repair the levator veli palatini muscle. Proper posture with a neutral cervical spine will help prolong a surgeon's career and ability to care for their patients.
Control of tip projection and rotation is critical to a successful rhinoplasty. GW3965 Suture techniques that change the relationship of the medial crura to the caudal septum can effectively manage tip position, but may be technically challenging or require specialized sutures. The authors present a technique ("tip delamination") that allows symmetrical exposure of the medial crura and caudal septum for accurate placement of projection control sutures using commonly available suture materials.

We describe a novel technique to completely expose (or delaminate) the medial crura of the lower lateral cartilages to allow for 360-degree access to and manipulation of these critical structures. We present a case series of 3 patients.

Exemplary cases with 1 intraoperative video will be reviewed to demonstrate how tip delamination allows for more precise control of the medial crura and nasal tip.

Nasal tip delamination is a simple technique for manipulating the medial crura and nasal tip in rhinoplasty procedures. Nasal tip delamination adds minimal time and morbidity to the procedure and offers significant control for the surgeon, with beneficial outcomes for the patient.

The use of radiofrequency in aesthetics has increased in popularity since the early 2000s. To date, there have been limited studies investigating the effect of thermal energy secondary to radiofrequency treatment. The purpose of this study was to evaluate perfusion and lymphatic assessment tools pre and post bipolar and fractional radiofrequency treatment.

A retrospective IRB-approved study was conducted between January 2019 and April 2019. Patients who were independently deemed appropriate candidates for radiofrequency soft tissue remodeling were evaluated. Diagnostic perfusion and lymphatic imaging obtained were reviewed using indocyanine green (SPY, Stryker) and optical coherence tomography (Vivosight OCT).

A total of 63 patients were treated during the study period, of which 37 had diagnostic perfusion and lymphatic imaging. Average patient age was 47 (STD 12), 95% (35/37) of patients were women, and no patients were active smokers. In total, 27% (10/37) of patients were post-surgical patients with recurrent laxity, 32% (12/37) did not have enough skin laxity to justify traditional excisions procedures, and 41% (15/37) may have been candidates for excisional procedures but were willing to accept more moderate results to avoid excisions surgery.
