Answer

The paralysis must include the forehead and lower aspect of the face. The patient may report the inability to close the eye or smile on the affected side. He or she also may report increased salivation on the side of the paralysis. If the paralysis involves only the lower portion of the face, a central cause should be suspected (ie, supranuclear). If the patient complains of contralateral weakness or diplopia in conjunction with the supranuclear facial palsy, a stroke or intracerebral lesion should be strongly suspected.
