There is no consensus on the cause of Bell's palsy, just as there is no proven medical therapy. Disregarding the numerous theoretic causes, preponderant anatomic, electrophysiologic, radiologic, clinical, and pathologic evidence supports entrapment at the medical foramen of the fallopian canal as a final common pathway resulting in facial nerve ischemia and degeneration. Middle cranial fossa decompression of the meatal foramen may benefit those patients most severely affected with Bell's palsy.
关于贝尔麻痹的病因尚无定论，就如同没有经过证实的医学疗法一样。尽管有众多理论上的病因，但占主导地位的解剖学、电生理学、放射学、临床及病理学证据支持，面神经在面神经管迷路段被卡压是导致面神经缺血和变性的最终共同途径。中颅窝面神经管迷路段减压术可能会使那些受贝尔麻痹影响最严重的患者受益。
