Central facial paralysis can be determined from clinical manifestations, cranial examination and differential diagnosis.
1. Clinical manifestations: central facial palsy has no paralysis of the muscles of the face and above the eyes, and only the muscles below the eyes on the side opposite to the lesion are paralyzed, i.e., symmetrical frontal stripe, symmetrical and powerful eye closure, shallow nasolabial groove, and crooked corners of the mouth, which is most common in cerebral vascular lesions, brain tumors, and encephalitis.
2. Craniocerebral examination: cranial CT or magnetic resonance examination can be used to find out the location of intracranial lesions.
3. Differential diagnosis: Differential with peripheral facial paralysis, peripheral facial paralysis is the paralysis of all the facial muscles in the lesion, the disappearance of casual and reflexive emotional movement, and there may be taste disorder. Most commonly seen in cold, ear or meningeal infection and neurofibroma.
When facial paralysis occurs, it is recommended to be under the guidance of a doctor.
