    Abstract Virtual reality (VR) and augmented reality (AR) have evolved since their introduction to medicine in the 1990s. More powerful software, the miniaturization of hardware, and greater accessibility and affordability enabled novel applications of such virtual tools in surgical practice. This scoping review aims to conduct a comprehensive analysis of the literature by including all articles between 2018 and 2021 pertaining to VR and AR and their use by plastic and craniofacial surgeons in a clinician-as-user, patient-specific manner. From the initial 1637 articles, 10 were eligible for final review. These discussed a variety of clinical applications: perforator flaps reconstruction, mastectomy reconstruction, lymphovenous anastomosis, metopic craniosynostosis, dermal filler injection, auricular reconstruction, facial vascularized composite allotransplantation, and facial artery mapping. More than half (60%) involved VR/AR use intraoperatively with the remainder (40%) examining preoperative use. The hardware used predominantly comprised HoloLens (40%) and smartphones (40%). In total, 9/10 Studies utilized an AR platform. This review found consensus that VR/AR in plastic and craniomaxillofacial surgery has been used to enhance surgeons' knowledge of patient-specific anatomy and potentially facilitated decreased intraoperative time via preoperative planning. However, further outcome-focused research is required to better establish the usability of this technology in everyday practice.

    Abstract Introduction: Several strategies have been shown to have some efficacy in the chronically infected total knee arthroplasty (TKA): chronic antibiotic suppression, a second two-stage revision, arthrodesis, and above-the-knee amputation (AKA). We conducted a systematic review to determine the efficacy of these treatments in patients who had previously received a two-stage revision.
    Methods: A systematic review of the literature was performed which investigated PubMed, Embase, Scopus, and Web of Science Databases. Chronic infection was defined as a persistent infection of a TKA after a previous two-stage revision. Studies were independently evaluated by two reviewers. Quality appraisal was performed using MINORS Criteria.
    Results: 14 studies were included for the final review. For chronically infected TKA, a second two-stage revision was often sufficient to control infection. If revision failed, the most common next procedure was either a repeat revision or AKA. AKA patients had less pain and higher quality of life scores compared to arthrodesis, but a higher five-year mortality rate.
    Discussion and conclusion: Chronic infection in TKA offers a multitude of challenges for orthopedic surgeons. We found that arthrodesis and AKA were not significantly different in rates of infection eradication or quality of life. We recommend clinicians to actively discuss options with patients to find a procedure most suitable for them.

    Abstract Mortality following a severe burn is influenced by both patient- and injury-factors, and a number of predictive models have been developed or applied. As there is no consensus on the optimal formula to use, we aimed to investigate the predictive value of the revised Baux score in comparison to other models when determining mortality risk in patients with burn injuries. A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The review yielded 21 relevant studies. The Prediction model Risk Of Bias ASsessment Tool quality appraisal checklist was used with many studies classified as "high" quality. All studies assessed the utility of the revised Baux score in comparison to other scoring systems such as the original Baux, Belgian Outcome in Burn Injury, Abbreviated Burn Severity Index, Acute Physiology and Chronic Health Evaluation II, Sequential Organ Failure Assessment, Boston Group/Ryan scores, the Fatality by Longevity, APACHE II score, Measured Extent of burn, and Sex model, and the Prognostic Burn Index. There was a range of 48 to 15975 participants per study, with a mean age range of 16 to 52 years old. The area under the curve (AUC) values of the rBaux score ranged from 0.682 to 0.99, with a summary AUC of 0.93 for all included studies (CI 0.91-0.95). This summary value demonstrates that the rBaux equation is a reliable predictor for mortality risk in heterogeneous populations. However, this study also identified that the rBaux equation has a diminished ability to predict mortality risk when applied to patients at both extremes of age, highlighting an important area for future research. Overall, the rBaux equation offers a relatively easy means to quickly assess the mortality risk from burn injury in a broad range of patient populations.

    Abstract Objective: To evaluate the effect of mask wearing on facial attractiveness and projected first impressions during the COVID-19 pandemic.
    Methods: A total of eight models were evaluated by 200 live raters and 750 online raters both with and without masks while smiling maximally. Both live and online raters looked at the models for 15 s, then completed a first impressions questionnaire.
    Results: Overall ratings for attractiveness were higher for both masked and unmasked conditions in-person versus online. Males were perceived more favorably both in impressions and attractiveness online when masked, whereas in person they were more favorable when unmasked. Females were perceived more favorably in impressions when unmasked both online and in person, but their attractiveness rating was higher when masked both online and in person. Regardless of gender and masking state, all first impressions were more favorable in person versus online. The differences were statistically significant (all p < 0.05).
    Conclusions: Face masks have different effects for males versus females in both an online and in-person setting. Men are perceived more positively in-person when they smile unmasked while they are better ranked online when they smile masked. Females are better perceived in all domains other than attractiveness when smiling unmasked both online and in person. To optimize first impressions, individuals should seek to meet in person whenever possible when forming new relationships.
