How is Bell's palsy diagnosed?
-
A doctor may be able to make a preliminary diagnosis of Bell's palsy by looking at the individual's face. The doctor will ask the individual to try to move the facial muscles and then will determine if nerve damage is present. Conditions, such as a stroke, infections, and tumors, also may cause facial muscle weakness, acting like Bell's palsy.
Imaging tests: Imaging tests, including computed tomography (CT scan), magnetic resonance imaging (MRI scan), and positron emission tomography (PET scan), may be used to detect nerve damage.
Other imaging tests: An electromyogram (EMG) may be performed. An EMG test is used to monitor electrical activity within the body and can help detect nerve and muscle disorders. EMG involves placing electrodes on the skin (surface EMG) or into the muscle (intramuscular EMG) to record electrical activity of the muscle.You should read product labels, and discuss all therapies with a qualified healthcare provider.

Riverside Center for Neurosciences answered:A diagnosis of Bell's palsy is made based on clinical evidence,-including a distorted facial appearance and the inability to move the muscles on the affected side of the face,-and by ruling out other possible causes of facial paralysis. There is no specific laboratory test to confirm a diagnosis of the disorder.
Generally, a physician examines the individual for upper and lower facial weakness. In most cases, this weakness is limited to one side of the face or occasionally to the forehead, eyelid, or mouth. A test called electromyography (EMG) can confirm the presence of nerve damage and determine the severity and the extent of nerve involvement. An X-ray of the skull can help rule out infection or tumor. A magnetic resonance imaging (MRI) or computed tomography (CT) scan can eliminate other causes of pressure on the facial nerve.
