Bilateral facial paralysis: a case presentation and literature review.
Bilateral facial paralysis is a diagnostic challenge, which may manifest itself as either a simultaneous or alternating form, occurring in 0.3-2.0% of patients that present with facial paralysis. The differential diagnosis of facial paralysis includes congenital, traumatic, neurologic, infectious, metabolic, neoplastic, toxic, iatrogenic and idiopathic etiologies. While idiopathic facial paralysis is the most common diagnosis, a comprehensive evaluation must be completed prior to this diagnosis in patients with bilateral facial paralysis. A representative case of simultaneous bilateral facial paralysis is presented. The literature is reviewed and discussed. A diagnostic protocol for the evaluation of bilateral facial paralysis is proposed. Bilateral facial paralysis requires a thorough evaluation and may prove to be a diagnostic dilemma.
