When hemifacial spasm occurs, it can affect the entire face, which has a great impact on the patient's appearance. Only by understanding the cause of hemifacial spasm can we carry out targeted treatment. So the causes of hemifacial spasm

1. Trauma, tumor or surgery are the causes of hemifacial spasm. It may be that the facial nerve has a short circuit with other cranial nerves during the recovery process. When other nerves are excited, facial muscles on one side may also twitch.

2. Compression causes pathological interference in facial nerve conduction. Most patients are caused by cross-compression of normal blood vessels, such as compression of the posterior inferior cerebellar artery, anterior inferior cerebellar artery, and vertebral nerve artery. Occasionally, due to arterial compression, It is caused by compression of the root of the facial nerve such as tumors, arteriovenous malformations, or brain tumors. This is also one of the causes of hemifacial spasm.

3. Another group of patients suffer from idiopathic facial nerve paralysis, and develop secondary muscle spasm of the affected face after recovery. It may be that facial neuritis causes pathological changes in nerve demyelination and fails to return to normal. There is still partial myelin loss, which makes the electrical conduction of the facial nerve susceptible to generalization, or facial neuritis involves the nerve nuclei in the brainstem, forming epileptic-like lesions and causing paroxysmal twitching of facial muscles.

The above is an introduction to the causes of facial muscle spasm. I believe everyone should have a certain understanding of facial muscle spasm. If you want to learn more about hemifacial spasm, talk to an online expert.
