Central facial paralysis is a disease of paralysis of the lower muscles of the face, that is, paralysis of the buccal muscles, osteotomy muscles, orbicularis oris.

Damage to any part of the ascending pathway of the facial nucleus can cause centrality

1. The facial expression muscles below the palpebral fissure are paralyzed. Above the palpebral fissure can frown, raise the eyebrows, close the eyes, the height of the eyebrows and the size of the palpebral fissure are the same as those on the contralateral side. The frontal wrinkle is equal to the lateral depth.

2, often accompanied by facial paralysis, ipsilateral limb paralysis, abnormal tendon reflexes,

The patient, a 62-year-old woman, had no obvious inducement and had a right angle of mouth, drooling at the left angle of mouth, numbness on the left face and upper limbs, weak left half, and clear consciousness. On the second day, the right angle of the mouth is more obvious. In the morning of the fourth day, the left upper limb was completely immobile and there was no speech disorder. The blood pressure is 180 / 110mmHg, the carotid pulses on both sides are roughly equal, the consciousness is clear, the arteriosclerosis fundus, the right eye fissure and the pupil are small, the left nasolabial sulcus is shallow, the corner of the mouth is oblique to the right, and the bilateral frontal lines are symmetrical. Tongue extension is to the left, left upper limb has no active movement, left lower limb is weak, left upper and lower limb muscle tension is high, tendon reflexes are bilaterally active, bilateral Babinski's sign is positive, the depth is normal, and there is no meningeal irritation sign. The cerebrospinal fluid pressure was 95mmHg, the cerebrospinal fluid test was normal, and the electroencephalogram showed a paroxysmal slow wave with a medium amplitude of 5-6 times / second on the right frontotemporal. The right carotid angiography showed that neither the middle cerebral artery nor the anterior artery above the siphon was visualized, and the posterior cerebral artery was normal. Left carotid angiography showed that both anterior cerebral arteries were visualized and in normal positions, the left side of the middle cerebral artery was normal, and the right cortical branches were not visualized. The diagnosis was: right internal carotid artery occlusion, and secondary right cerebral middle cerebral artery cortical branch infarction.
