Facial muscle spasm presents as paroxysmal hemifacial muscle involuntary twitches. Most of the facial twitches are unilateral symptoms, and very few (less than 1%) are bilateral sequential attacks. Since patients mostly have no pain sensation, the early treatment rate is low. So, under what circumstances does facial twitching need to be operated? 1.Facial twitching affects work. If you are engaged in teaching, sales, front desk service, etc., when you must deal with many people, facial twitching will affect the communication between the two sides. 2. Twitching even closes the eyes and affects vision. 3, Because of the long-term twitching, the face feels very uncomfortable and does not feel relaxed. Generally speaking, facial twitching is a disease that gets worse and worse, so don’t report it in the hope that it will get better in the future. If you feel that facial twitching is bothering your working life, it is better to decide on surgery as soon as possible. The current technological development is getting higher and higher, and this surgery is getting safer and safer. The treatment of facial muscle spasm is divided into the following methods: medication: including carbamazepine, oxcarbazepine, etc., drugs that inhibit nerve discharge, but the effect is generally limited, and the symptoms recover after stopping the drug. Botulinum toxin treatment: The efficacy is certain, but botulinum toxin generally only lasts 3-6 months and there is a slight facial paralysis after injection. Facial spasm surgery: Surgery refers to microvascular decompression, and this surgery is the only surgical method that can cure facial spasm so far. It has high efficiency (>95%), low incidence of risk and low recurrence rate. The surgery is minimally invasive. What do I need to prepare before facial spasm surgery? A 2-3 day preparation is required before surgery to check blood count, coagulation tetralogy, blood sugar and special MRI. Microvascular decompression can be performed after meeting the surgical criteria. The earlier the facial myospasm is treated, the better the result will be, and choosing a regular tertiary hospital neurosurgery department is the prerequisite and basis for the cure.
