Bell's palsy. Actions for this page Listen Print. Summary Read the full fact sheet. On this page. Bell's palsy is a paralysis or weakness of the muscles on one side of the face, with young adults of either sex more susceptible for unknown reasons.
The facial nerve services the muscles of the face, the ear, salivary and tear glands, and provides some of the sensations of taste on the tongue. This nerve enters the skull via a small opening in the petrous temporal bone at the base of the skull.
In Bell's palsy, the facial nerve swells and the resulting inflammation disrupts the relay of nervous system messages. The paralysis can be partial or total. Request an Appointment at Mayo Clinic.
