The treatment of facial spasm is divided into conservative treatment and surgical treatment. Conservative treatment includes oral medication and drug injection facial nerve block treatment, there is no special oral medication, clinical use of some sedative and tranquilizing drugs; drug injection treatment is the use of botulinum toxin, ethanol drugs to block the conduction function of the facial nerve, so that the facial muscle spasm is lifted. After the injection, the nerve conduction is impaired and the facial muscle is immediately paralyzed or incompletely paralyzed, and such facial muscle paralysis can be recovered within a few months. The effect is short-lived, and most patients relapse in about 3-6 months, requiring re-injection treatment. Repeated injections may cause permanent facial paralysis. Common complications include facial palsy, dry eyes, diplopia, and swallowing difficulties. Surgical treatment currently focuses on microvascular decompression. Microvascular decompression was pioneered by an American neurosurgeon in the late 1960s. The procedure is performed under a surgical microscope to push away the blood vessels that are located at the root of the facial nerve and cause compression of the facial nerve, and to fix them so that they do not touch the facial nerve, thus relieving the compression of the facial nerve root and restoring the normal function of the facial nerve. The facial muscle spasm will stop immediately or gradually. Since the 1980s, this surgical method has become the preferred treatment for facial spasm internationally, and to date, more than 50,000 patients worldwide have undergone surgery for facial spasm. With the improvement of this surgical technique, especially its minimally invasive, high safety, remarkable effect and low recurrence rate and complications, especially the complete preservation of vascular and nerve function, it was soon accepted by neurosurgeons all over the world and was promoted worldwide as the most effective treatment for facial spasm.
