The aim of this study was to examine changes in the electromyographic activity, thickness, width, and hardness of the masseter muscle from before to after orthognathic surgery. ⋯ The authors' findings indicate that despite improved muscle activity and dimensions, postoperative 3 months is still early period for adaptation of the masseter muscles to the new occlusion and skeletal morphology.

On January 8, 2020, a novel coronavirus was officially announced as the causative pathogen of coronavirus disease (COVID-19) by the Chinese Center for Disease Control and Prevention. On February 26, COVID-19 has been recognized in 34 countries, with a total of 80,239 laboratory-confirmed patients and 2700 deaths. ⋯ In addition, being able to protect healthcare workers, constituting the front-line response against high-threat respiratory pathogens, such as severe acute respiratory syndrome coronavirus 2, is important for reducing secondary transmission in healthcare-associated outbreaks. Authors present a simple, reliable, and cheap protocol to produce a custom-made sterilizable filtering facepiece 2/3 masks for healthcare providers during pandemic COVID-19 emergency.

The current outbreak of the highly contagious, animal origin SARS-CoV-2 virus causes the disease COVID-19. The disease is globally pandemic and as per World Health Organization (WHO) has spread to 235 countries. There is global lockdown for containment of the virus transmission. ⋯ WHO recommends nasopharyngeal (NP) and oropharyngeal (OP) swab for the quantitative assessment of SARS-CoV-2 RNA level through real-time reverse transcription polymerase chain reaction (rRT-PCR). The virus is shown to be consistently present in saliva and rRTPCR of saliva specimens and have advantages over NP and OP swabs such as self-collection of saliva, avoidance of healthcare workers for specimen collection, cost-effectiveness, etc. This article explores the current literature and suggests saliva as an emerging potential diagnostic specimen for COVID-19 testing.

All around world, the COVID-19 pandemic is accelerating, and any insight we can learn from our colleagues who have either encountered or are currently going through this will be used to protect our patients, our medical staff, and ourselves. No one knows to the best of our understanding whether or not COVID-19 includes the respiratory mucosal lining the middle ear and mastoid air cell system-but it seems probable they do. ⋯ Powered air purifying respirators are supplied even shorter than N95 masks, but strongly believed they are important for our team safety and protection. This mini review provides fundamental knowledge on otologic surgery feasibility in the COVID-19 pandemic from an objective perspective.
