A Case of COVID-19 Pneumonia Referred to the Otolaryngology Department with Suspected Chronic Rhinosinusitis

COVID-19 pneumonia is a respiratory disease mainly manifesting with the symptoms of fever, cough and malaise While the condition is mild and improves spontaneously in about 80% of patients, some patients need mechanical ventilation or extracorporeal membrane oxygenation (ECMO) Some patients present to the department of otolaryngology because of olfactory disturbance during the course of the disease It is often difficult to differentiate the disease from other diseases due to the absence of fever Herein, we report the case of a patient who was referred to our department as a suspected case of chronic sinusitis after several medical examinations, and was subsequently confirmed as having COVID-19 pneumonia Although the otolaryngologist was not aware that the patient had COVID-19 pneumonia at the time of examination, appropriate infection prevention measures, including wearing of an N95 mask, were taken to reduce the risk of infection of the staff in this case It is expected that otolaryngologists will examine more and more COVID-19 patients without typical symptoms In order to prevent infection among the medical staff, it is important to carefully interview each case and take appropriate precautions © 2020 Society of Practical Otolaryngology All rights reserved
