Detailed explanation-1: -Bell’s palsy is the most common cause of facial paralysis, although its exact cause is unknown. It results from dysfunction of cranial nerve VII, which connects your brain to the muscles that control facial expression (the nerve also is involved with taste and ear sensation).
Detailed explanation-2: -Bell’s palsy is marked by a droopy appearance on one side of the face and the inability to open or close your eye on the affected side. In rare cases, Bell’s palsy may affect both sides of your face. Other signs and symptoms of Bell’s palsy include: facial weakness.
Detailed explanation-3: -Paralysis can occur if any part of the facial nerve, called the seventh cranial nerve, becomes inflamed or damaged. The facial nerve has branches throughout both sides of the face and controls many muscle groups, including those in the brow, eyelid, cheek, and lips.
