Analysis:

Hemifacial spasm is a paroxysmal involuntary convulsion of one muscle and eyelid. Although there is no life-threatening, repeated facial muscle twitching often makes people feel embarrassed.

There are many reasons for hemifacial spasm, which can be the sequela of facial nerve, the lesion of intracranial facial nerve motor nucleus or facial nerve, and one of the manifestations of localized epilepsy caused by the lesion of cerebral cortex motor area. But more often, there is no obvious reason, which is called primary hemifacial spasm.

Primary hemifacial spasm mostly occurs in adult women. At first, it may only be a slight twitch of the upper and lower eyelids or mouth, and then it may spread to other muscles on the same side. Occasional mouth twitching or eyelid twitching is the most obvious. Patients have the most obvious convulsions in public places such as talking and making reports. Therefore, when interacting with people, the patient's mood will become nervous because of fear of attack. The more nervous, the more obvious the attack and the heavier the mental burden.

Can hemifacial spasm be cured? The answer is yes. Here are several main treatment methods.

(1) drug therapy: such as diazepam, lumina, carbamazepine, phenytoin sodium, etc. can alleviate the symptoms of a few patients. Muscle relaxants such as chlorzoxazone also have certain effects.

(2) Physical therapy: such as calcium iontophoresis, advection, radiofrequency thermocoagulation, etc.

(3) Ethanol injection therapy: If the above drugs or physical therapy are ineffective and the symptoms are serious, ethanol injection therapy can be considered. Injecting ethanol with different concentrations until absolute ethanol is injected into nerve trunk can temporarily interrupt the conduction function of facial nerve and relieve hemifacial spasm.

(4) Botulinum toxin type A injection therapy: Botulinum toxin type A is injected into facial motor nerve endings to produce muscle flaccid paralysis, thus achieving the purpose of spasmolysis. Spasm was quickly relieved in a short time after injection, and no side effects were found after repeated injection.

(5) Triple injection therapy: This is the hemifacial spasm therapy adopted by the author in practice. The main method is to inject hormones, diazepam and other drugs into stylomastoid foramen, the middle point of preauricular folds and facial movement points according to the specific conditions of patients, so as to effectively relieve hemifacial spasm. The advantages of this method are simple, painless, easily accepted by patients, small local side effects and no allergic reaction after repeated injections.
