  • Describe the mechanism of his muscle weakness:
    Bell’s palsy is brought on by inflammation or a viral infection that affects the cranial nerve VII which regulates the muscles of expression. The facial nerve travels through the temporal bone's tiny facial canal. Inflammation in this small area can compress the nerve, paralyzing the muscles it connects partially or entirely. Simply, nerve signals to the muscles are hindered, causing weakness or paralysis.

  • Other symptoms that the patient could exhibit as a result of facial muscle weakness:

    • Headache

    • Sensitivity to sound

    • Drooling

    • Altered taste sensations

    • Difficulty speaking, eating, or drinking
