What is facial paralysis?

Facial neuritis, commonly known as facial nerve paralysis (i.e. facial nerve paralysis), "crooked mouth" and "hanging wire wind", is a disease characterized by motor dysfunction of facial expression muscles. It is a common and frequently occurring disease that is not limited by age. The common symptoms are facial paralysis and eye deviation, and patients are often unable to complete even the most basic movements such as raising eyebrows, closing eyes, and puffing out lips.

Causes of facial paralysis:

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.

The 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.
