Facial paralysis has numerous etiologies ranging from the most common, Bell's palsy and trauma, to rare tumors and congenital anomalies. This paper divides the etiologies of facial paralysis into five major classifications: idiopathic, traumatic, infectious, neoplastic and neurologic. The incidence of each of these classifications has been estimated from incidence rate information published in the United States and abroad. Using this information, an estimate of the incidence rate has been determined. This information was previously untabulated, thus making statistical analysis nearly impossible regarding this disorder.
面瘫有众多病因，从最常见的贝尔麻痹和外伤，到罕见的肿瘤及先天性异常。本文将面瘫的病因分为五大类：特发性、外伤性、感染性、肿瘤性和神经性。这些分类中每一类的发病率是根据美国及国外发表的发病率信息估算得出的。利用这些信息，确定了发病率的估算值。此前这些信息未制成表格，因此几乎无法对这种疾病进行统计分析。
