Bilateral facial paralysis is a rare condition and therefore represents a diagnostic challenge. We report the case of a year-old healthy woman with sequential bilateral facial paralysis as a sole manifestation of sarcoidosis. She initially presented with an isolated left sided Bell's palsy without any symptoms to suggest alternative diagnoses. Within a month there was progression to peripheral facial paresis on the contra lateral side, prompting a diagnosis of Lyme disease.

Love Marianna R. Beattie Isolated facial numbness often is descriptive of impairment of sensation of the face as a result of dysfunction of the trigeminal system or central trigeminal pathways. Patients may report unilateral or bilateral facial numbness, paresthesia a spontaneous abnormal sensation , or dysesthesia an unpleasant abnormal sensation produced by normal stimuli. There may be associated symptoms of altered sensation of the mucous membranes of the nose, mouth, gums, palate, or teeth.
