Bilateral facial paralysis is when both sides of the face are affected, with weakness or the total loss of facial movement.
Additional Causes of Facial Paralysis
Other causes of bilateral facial paralysis include bilateral skull fractures involving both temporal bones, certain kinds of brain infections like meningitis, and certain cancers like lymphoma that get into the spinal fluid, causing bilateral weakness. Sarcoidosis, a granulomatous (characterized by a mass or nodule of inflamed tissue) a response to inflammation) disease can also cause bilateral facial paralysis, as can certain kinds of leukemia, infectious mononucleosis, and acute HIV infection. Each underlying cause necessitates a unique approach to diagnosis and management.
