The causes of facial nerve paralysis are usually

There are many causes of facial nerve paralysis. Facial nerve paralysis can be divided into two types: central facial neuritis and peripheral facial neuritis. Diseases such as infectious lesions, tumors or diabetes can cause facial nerve paralysis.

1. There are many causes of facial neuritis. Clinically, it can be divided into central facial neuritis and peripheral facial neuritis according to the site of damage. The lesions of central facial neuritis are located in the corticobulbar tract between the facial nerve nucleus and the cerebral cortex, and are usually caused by cerebrovascular disease, intracranial tumors, brain trauma, inflammation, etc. Peripheral facial neuritis lesions occur in the facial nerve nucleus and facial nerve.

2. Common causes of peripheral facial neuritis are: ① infectious lesions, mostly caused by the activation of viruses lurking in the sensory ganglia of the facial nerve; ② ear diseases, such as otitis media; ③ autoimmune reactions; ④ tumors; ⑤ neurogenic; ⑥ trauma; ⑦ poisoning, such as alcohol poisoning, long-term exposure to toxic substances; ⑧ metabolic disorders, such as diabetes, vitamin deficiency; ⑨ vascular insufficiency; ⑩ congenital facial nerve nuclear dysplasia.

3. Nursing

1. Eye care

During the acute phase, avoid outdoor activities and keep eyes clean; cover the affected eye with an eye patch or apply eye ointment to prevent conjunctival and corneal infections; minimize eye use.

2.Diet care

Patients with taste disorders should pay attention to the temperature of food; avoid hard food; try to place food behind the healthy tongue and chew slowly; remember to rinse your mouth in time after meals to keep your mouth clean.

3. Rehabilitation care

You can apply hot compress to the affected side to promote local blood circulation. When the facial muscles begin to recover, facial muscle strength training is required, focusing on training the facial muscles, such as opening the eyes, wrinkling the forehead, sucking, curling the lips, smiling, raising the corners of the mouth, whistling, pursing the lips, pulling the lower jaw, etc., each time for about 20 minutes, once a day, until final recovery.
