Bells palsy is a condition caused by trauma to the 7th cranial nerve that weakens or paralyzes one side of the facial muscles. It is often misconceived as a stroke, it is in fact the most common cause of facial paralysis. Approximately 0.02% of the worldwide population and 1 of every 5000 people suffer from the disorder every year.
Causes of Bell's Palsy
The exact cause of Bell's Palsy is still unknown. Most scientists now believe that a viral infection such as viral meningitis or common cold sore virus- herpes simplex, causes the disorder when the facial nerve swells and is inflamed due to the infection.
Who is at greater risk?
Usually older people are more likely to be afflicted, but children are not immune to it although they tend to recover well. Diabetics are 4 times more likely to develop Bells Palsy, and conditions that compromise the immune system such as HIV or sarciodosis increase the possibility of this disorder to occur and recur.
What are the signs and symptoms?
Signs/ Symptoms of Bell's Palsy ranges from mild weakness to total paralysis and may include:
-Weakness or paralysis of one side of the face
-Pain in the mastiod region
-Drooping eyelid or corner of the mouth
-Dry eyes or mouth, reduced sense of taste
The symptoms usually begin suddenly and reach their peak within 48 hours.
Treatment of Bell's Palsy
Treatment includes medication, PT and acupuncture
-Acylovir: to fight viral infections
-Prednisone: to reduce inflammation and swelling
Physical Therapy (PT):
-Moist heat massage
-Facial muscle stimulation (ice, electrolytes)
-Facial muscle exercises

Prognosis of Bell's Palsy
Prognosis of Bell's Palsy is good. 80% of patients recover completely within three to six months even without treatment. If untreated, 20% of cases have long term residual problems such as muscle weakness, muscle spasm and facial asymmetry.
