It turns out there are 4 signs of facial paralysis

Facial paralysis is a common disease in daily life. Patients generally show symptoms of facial paralysis, which not only seriously affects people's appearance, but also makes patients unable to complete their proper facial expressions, seriously affecting the physical and mental health of patients with facial paralysis. Therefore, it is particularly important to understand the signs of facial paralysis and treat it in time. In fact, there are four signs of facial paralysis, and eyelid tremor is one of them.

1. Eyelid tremor: It is a common symptom of mild facial paralysis. Close both eyes forcefully, and the examiner will pull the upper eyelids open. At this time, a slight muscle contracture tremor may be felt on one side of the upper eyelid, but not on the other side. The existence of this phenomenon indicates mild facial nerve paralysis, which is more common in peripheral facial nerve paralysis.

2. Blinking movement: Carefully observe the patient's blinking. Symptoms of mild facial paralysis can be seen in asymmetric blinking movements on both sides, which is a significant phenomenon. If the patient is asked to blink, the blinking movement will be slow and incomplete on the mildly paralyzed side.

3. Oblique oval mouth sign: Ask the patient to open his mouth wide. When there is mild facial nerve paralysis, the corner of the mouth on the affected side droops to form an oblique oval-shaped mouth, which is also a symptom of mild facial paralysis. The difference between the oblique oval mouth caused by trigeminal nerve motor branch paralysis and the oval mouth caused by trigeminal nerve motor branch paralysis is that there is no mandibular deviation. This sign is not obvious in central facial nerve paralysis.

4. Eyelash sign: Ask the patient to close his eyes forcefully. When a normal person closes his eyes forcefully, his eyelashes are mostly buried between the upper and lower eyelids. When the facial nerve is paralyzed, the eyelashes are exposed, especially in the case of mild paralysis. If you close your eyes tightly, the asymmetry of the eyelashes is not obvious at first, but after a short period of time, the eyelashes on the mildly paralyzed side will slowly become visible. This is called a positive eyelash sign. This is a common symptom of mild facial paralysis.
