Facial nerve palsy may be a possible neurological manifestation of COVID-19 infection; this may be due to cranial nerve deficits as a result of immune-mediated mechanisms.
Why this matters
The full range of neurological manifestations of COVID-19 infection remain unclear. Facial nerve palsy has been associated with several viruses including herpes simplex, varicella zoster, and human immunodeficiency viruses. Understanding the possible association between COVID-19 infection and facial nerve palsy is important for the diagnosis of COVID-19.
