Facial muscle spasm is usually treated with medication, and then surgery is considered when local Botox injections are not effective. Facial muscle spasm is a non-specific disease of the facial nerve, the specific mechanism that causes it is not completely clear, some patients are caused by the compression of the facial nerve, most of them are caused by the compression of the adjacent vascular collaterals. Therefore, surgery can be performed by decompression of the vessels around the facial nerve to relieve the compression of the facial nerve and relieve the symptoms, or by peripheral neurotomy to end the symptoms completely, but the latter has more side effects and can cause facial nerve paralysis and facial muscle paralysis. The preferred treatment for this disease is local injection of botulinum toxin A. You can also choose to take oral carbamazepine or clonazepam, gabapentin, etc. If medical treatment is not effective, then consider surgery.
