Is coronavirus one of the new etiologies of facial nerve paralysis? A case report study

Abstract

Coronaviruses are important pathogens in humans and animals. Two years ago, a new coronavirus was identified as the cause of pneumonia and adult respiratory distress syndrome. These viruses have many clinical features, and new features are created daily. Bell's palsy is sporadic facial nerve palsy. The main reason of Bell's palsy is not recognized. Many viruses, such as herpes simplex or herpes zosters, have been previously identified as Bell's palsy. This case report seeks to explain the occurrence of Bell's palsy in a patient infected with coronavirus. The polymerase chain reaction test of a 60-year-old woman was positive for SARS-CoV-2. Bell's palsy happened on the 2nd day of admission to intensive care unit and recovered by the 12(th) day. After ruling out other etiologies of Bell's palsy, coronavirus appears to be one of the new etiologies of Bell's palsy.
