What Is Bell's Palsy?
Reviewed: Dr. Gromatzky
8. Diagnosis
Bell’s palsy is generally diagnosed by physical examination. The most common clinical presentation is the inability to move the facial muscles of one side, and the characteristic facial appearance. It is essential to exclude other causes of facial paralysis.
However, there is no specific test to diagnose Bell’s palsy. Electromyography is done to confirm the facial nerve damage and determine the site and severity of the damage. Blood tests are done to see whether the patient has other diseases or not. Magnetic resonance imaging and a CT scan is done to exclude any structural causes of the condition.
