Bilateral Simultaneous Facial Nerve Palsy

Abstract

Bell's palsy is the most common cause of BS-FNP in authors' centers. Although BS-FNP may show more severe paralysis, the overall prognosis in most cases is as good as that in unilateral FNP, excluding life-threatening or traumatic cases. Differential diagnosis is very important because the treatment outcome of BS-FNP depends on the cause.
