The facial nerve is damaged most commonly by swelling within the facial canal in the temporal bone that results from viral infection. This causes Bell palsy, an abrupt weakness of all the facial muscles on one side of the face that is often accompanied by pain around the ear, unusual loudness of sounds on the same side, and loss of taste on the front of the tongue.
