They may also drool and find it difficult to chew food. People with Bell’s palsy can find it difficult to close their eyelid on the affected side. If the facial nerve is inflammed it can interfere with the signals that the brain sends to muscles in the face, causing one side of the face to become paralysed. For these nerves to do this, they must pass through a passage of bone near the upper jaw. As with almost every nerve, the facial nerve is connected to the brain to either carry information from the brain to control muscles or return information to the brain relating to sensory information. ![]() ![]() The condition occurs when the facial nerve becomes inflammed. Bell’s palsy is a – usually – self-limiting condition that causes paralysis to one side of a person’s face. ![]()
