Primary facial spasm is a persistent disease with an incidence of about 1-6 per 100,000 people. The initial manifestation of the disease is unilateral eyelid jumping that cannot be controlled by oneself, gradually developing into facial and corner of the mouth twitching, and when the attack is severe, the eyes cannot be opened and the corners of the mouth are skewed. The disease has a tendency of progressive aggravation, and many patients have sought medical treatment in many places, after taking Chinese medicine, acupuncture and massage, botulinum toxin A injection and other methods of treatment, but the effect is not obvious or the effect is not lasting, so patients are deeply distressed and distressed. What is the cause of primary facial spasm and can it be cured? It has been confirmed that the majority of primary facial spasms are caused by intracranial vascular compression of the facial nerve roots and increased nerve excitability. Currently, the internationally recognized method to cure primary facial myospasm is a minimally invasive surgery – microvascular decompression. This procedure was initiated by Dr. Jannetta in the 1960s and was designed to treat the root of the facial nerve by intracranial vascular compression, so to speak, from the root. With the continuous advancement and improvement of micro-neurosurgical techniques and equipment, the safety and effectiveness of this surgical approach have been further improved, trauma has been further reduced, the efficiency can reach more than 95%, the recurrence rate is generally less than 5%, and there are few long-term complications, so it is considered the preferred treatment for facial spasm. The procedure is performed under general anesthesia and is painless for the patient. The incision is made in the hairline behind the affected ear and is about 4 cm long. Under the operating microscope, a small hole of 2 cm in diameter is drilled in the skull to remove the blood vessel at the root of the facial nerve that is causing the compression of the facial nerve, and a special cotton pad is used to fix it. Of course, before using surgical treatment, we should first exclude the facial muscle spasm secondary to traumatic facial palsy, eyelid jumping caused by mental tension, hysterical facial twitching, etc., and determine the primary facial muscle spasm before undergoing surgery.
