Bell's Palsy Diagnosis & Tests
Examination shows upper and lower facial weakness, which is almost always isolated to one side of the face or occasionally to the forehead, eyelid, or mouth. Despite subjective sensory symptoms, the loss of sensation on examination is a rare and disturbing finding. Blood pressure is normal. If there are no other abnormalities on examination, no imaging studies are usually done.
Blood tests for sarcoidosis or Lyme disease may be considered under some circumstances. If there is no improvement in the facial paralysis after several weeks, an MRI is done to rule out other causes of the dysfunction. An EMG and nerve conduction studies may also be done to determine the severity of nerve damage.
