ReviewReview of Indoor Aerosol Generation, Transport and Control in the Context of COVID-19.
The coronavirus disease-2019 (COVID-19) pandemic has heightened the awareness of aerosol generation by human expiratory events and their potential role in viral respiratory disease transmission. Concerns over high severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) viral burden of mucosal surfaces has raised questions about the aerosol-generating potential and dangers of many otorhinolaryngologic procedures. However, the risks of aerosol generation and associated viral transmission by droplet or airborne routes for many otorhinolaryngology procedures are largely unknown. ⋯ Herein we elaborate on known aerosol vs droplet properties, indoor airflow, and aerosol-generating events to provide context for risks of aerosol infectious transmission. We also provide simple but typically effective measures for mitigating the spread and inhalation of viral aerosols in indoor settings. Understanding principles of infectious transmission, aerosol and droplet generation, as well as concepts of indoor airflow, will assist in the integration of new data on SARS-CoV-2 transmission and activities that can generate aerosol to best inform on the need for escalation or de-escalation from current societal and institutional guidelines for protection during aerosol-generating procedures.

Review Meta AnalysisSystematic review and meta-analysis of total intravenous anesthesia and endoscopic sinus surgery.
Total intravenous anesthesia (TIVA) has been shown in some studies to impact visual field, blood loss, and cardiovascular parameters during endoscopic sinus surgery when compared to inhalational anesthesia (IA). These variables are critical in endoscopic sinus surgery. A systematic review and meta-analysis was undertaken to discern the impact of TIVA vs IA in endoscopic sinus surgery. ⋯ Current evidence supporting TIVA is limited to a handful of inconsistently controlled and reported studies. Standardized grading of visibility scores and preoperative characteristics would better establish the role of TIVA in endoscopic sinus surgery.

Assessment of three types of intranasal nebulization devices in three-dimensional printed models and volunteers: a pilot study.
Intranasal nebulization is an effective treatment for chronic rhinosinusitis and allergic rhinitis; however, terminal inhalation devices have not been fully studied. We compared the sinonasal aerosol distributions and adverse effects of different inhalation units. ⋯ The single-head nozzle was the most effective device in aerosol delivery to the lateral wall of the nasal cavity and sinuses; conversely, the mask yielded limited sinonasal deposition. Intranasal nebulization was well tolerated, and the adverse effects among the devices were comparable. These findings are meaningful for selecting and developing inhalation units.

Gender and authorship trends in rhinology, allergy, and skull-base literature from 2008 to 2018.
A recent analysis suggested potential narrowing of the gender gap in research productivity in the field of rhinology. This analysis did not, however, provide insight into how the genders are represented in the rhinologic literature. This study aimed to evaluate 11 years of literature to evaluate for gender differences in authorship position, collaborations, category and content of research, citations, and funding to gain perspective on how gender and authorship has changed over time. ⋯ This study represents the first assessment of gender differences in the rhinology literature. Areas where female representation can improve include senior authorship, increased involvement in skull base publications, and increased funding.

ReviewSkull-base surgery during the COVID-19 pandemic: the Italian Skull Base Society recommendations.
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), is highly contagious with devastating impacts for healthcare systems worldwide. Medical staff are at high risk of viral contamination and it is imperative to know what personal protective equipment (PPE) is appropriate for each situation. Furthermore, elective clinics and operations have been reduced in order to mobilize manpower to the acute specialties combating the outbreak; appropriate differentiation between patients who require immediate care and those who can receive telephone consultation or whose treatment might viably be postponed is therefore crucial. ⋯ In all cases the use of drills, which promote the aerosolization of potentially infected mucous particles, should be avoided. Given the potential neurotropism of SARS-CoV-2, dura handling should be minimized. It is only through widely-agreed protocols and teamwork that we will be able to deal with the evolving and complex implications of this new pandemic.
