Numerous causes of peripheral facial nerve paralyses have been described; however, none has satisfactorily explained the genesis of the most common type of paralysis, Bell's palsy. Two patients undergoing an experimental embolization of vascular intracranial tumors suffered a total peripheral facial nerve paralysis when occlusion of the middle meningeal artery had been accomplished. It is speculated that this paralysis resulted from ischemia of the horizontal portion of the facial nerve, an observation that has not previously been described and that might be applicable as well to the etiology of Bell's palsy.
