Facial paralysis occurs during a stroke when nerves that control the muscles in the face are damaged in the brain. Depending on the type of stroke, damage to the brain cells is caused by either lack of oxygen or excess pressure on the brain cells caused by bleeding.
What are the main causes of facial paralysis?
An inability to move the muscles of the face on one or both sides is known as facial paralysis. Facial paralysis can result from nerve damage due to congenital (present at birth) conditions, trauma or disease, such as stroke, brain tumor or Bells palsy.
Can you recover from facial paralysis?
How long does Bells palsy last? In the majority of cases, facial paralysis from Bells palsy is temporary. Youre likely to notice gradual improvement after about two weeks. Within three months, most people have recovered full motion and function of their face.
What causes facial droop besides stroke?
Bells palsy is a temporary paralysis of the facial muscles, causing drooping and weakness on one side of the face, and is sometimes mistaken for a stroke.
Do facial nerves repair themselves?
Facial nerve repair is infrequently required, because most of these patients regain function spontaneously. When paralysis is permanent, some advocate facial nerve decompression in selected cases.
