TCM diagnosis Based on Syndrome Differentiation:
In traditional Chinese medicine (TCM), the diagnosis for Bell’s Palsy is termed "External Wind-Cold attacking the channels of the face". According to TCM principles, one of the main implications of this condition is an underlying qi (a person’s inherent energy) deficiency. In China, acupuncture has been used for thousands of years to assist in Bell’s Palsy recovery, and the initial treatment goal according to TCM would be to expel Wind and resolve Damp, as well as to invigorate qi and promote blood circulation to the face. Consistent acupuncture treatments (usually recommended once or twice per week), can help soothe a patient, expedite the paralysis from dissipating, and enhance nerve function.

Diagnosis in Western Medicine:
Bell's palsy is strongly suggested by its characteristic symptoms. It is not a life-threatening condition but it can produce symptoms similar to other more serious causes for facial paralysis, such as a stroke or tumour. For this reason, other possible causes for the symptoms must be excluded before a definitive diagnosis of Bell's palsy can be made. In order to confirm the diagnosis the doctor may undertake the following:
 
-- Blood tests
-- Hearing tests
-- Balance tests
-- Taste and salivation tests
-- Discussion of current symptoms
-- A full medical history, including any recent illnesses or viral infections
-- Computerised tomography (CT) or magnetic resonance imaging (MRI)
-- Electrical tests (electromyography) to measure the functioning of the nerve.
-- A complete physical and neurological assessment eg: sensation in the face, the strength of the facial muscles
-- To assist further with the diagnosis and to rule out other conditions, the doctor may recommend:
-- Tear test (to measure the eye’s ability to produce tears)
