Bell’s Palsy

  • Temporary Facial paralysis
  • Mild muscle weakness


Bell’s Palsy results from nerve damage or trauma to one of the two facial nerves. There is one facial nerve on either side of the face.

Bell’s Palsy occurs when the nerve that controls the facial muscles is swollen, inflamed, or compressed, resulting in facial weakness or paralysis

Facial Nerve

  • Cranial nerve VII: The facial nerve emerges from the brainstem between the pons and the medulla, and controls the muscles of facial expression, and taste to the anterior two-thirds of the tongue.

Facial Nerve Functions:

  •  control eye blinking and closing
  • facial expressions such as smiling and frowning
  • carries nerve impulses to the lacrimal or tear glands, and the saliva glands
  • Innervates the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue.
