Facial muscle spasm surgery is to do microvascular decompression surgery, as long as the patient is awake with normal anesthesia, the general anesthesia awake 6-8 hours after the clinical feeding, provided that the patient is observed to recover the degree of wakefulness after surgery. Because the surgery is minimally invasive, as long as the experienced neurosurgeon operates, the patient is awake after the surgery with normal anesthesia, most patients can resume eating in about 6-8 hours. After facial muscle spasm surgery, if the patient is awake, if the reaction of anesthesia drugs has not passed, if there is still nausea, vomiting, etc., we have to wait for the reaction of anesthesia drugs to disappear, and wait for the patient to be fully awake, no vomiting, etc., to be able to cooperate with eating, and to resume the normal swallowing action, before we can give the patient to eat. Just woke up, the patient must be especially careful to eat, some people may not have passed the postoperative anesthetic reaction, in case of vomiting, be careful not to cause aspiration, choking, etc., but most patients can eat in 6-8 hours.
