Bell's Palsy is not synonymous with facial nerve paralysis. While it is a common cause of facial nerve paralysis, it is a diagnosis of exclusion and other causes of facial nerve paralysis should be ruled out by appropriate evaluation and follow-up. A case report is presented of a patient with a facial nerve paralysis, which was initially diagnosed as Bell's Palsy, but which was found to be a poorly differentiated parotid malignancy causing facial nerve paralysis. A review and discussion of Bells Palsy, evaluation and treatment is presented.
