What should I do if my facial spasm surgery recurs? Some patients ask what to do if the symptoms of facial myasthenia are healed after surgery, but after some time they come back. Microvascular decompression can be used for facial myospasm surgery. The cure rate of microvascular decompression is as high as 98%, and there are two types of effective patients: 2/3 patients have immediate disappearance of post-operative myospasm, and 1/3 patients still have post-operative myospasm, but it will disappear within 2 weeks-12 months, which is called delayed cure. The ineffectiveness rate is 2%-3%. The ineffectiveness may be due to the tight adhesion of the vessel to the nerve that cannot be separated or the missed responsible vessel. There is a 2%-3% recurrence rate after surgery, and re-surgical treatment remains effective after recurrence. There are many causes of recurrence after facial spasm, which are manifested as follows: 1. Since the blood vessels continue to gradually tortuous with age, if the implanted pad cotton cannot block the blood vessels that have become longer, it may produce a disease. 2, The first operation, if the vascular pressure is very high, after barely lifting, the pressure of the contralateral vessel continues to increase, which may break the blockage of the pad cotton and squeeze on the facial nerve again causing recurrence, this situation is mostly seen in cases where the thick vertebrobasilar artery is involved in compression. 3. Physician inexperience. Recurrence can also be caused by immature surgical techniques, inadequate surgical decompression or deviation in decompression position. 4, The first surgical pad cotton was displaced or the pad cotton was dissolved and thinned or disappeared, and there may be a problem with the quality of the pad cotton. 5, When the surrounding non-responsible vessels lengthen with age, they may also become new responsible vessels, leading to recurrence of facial myoclonus. It has been clinically found that recurrent cases are usually able to be operated again, and the postoperative treatment is better. Why is facial myospasm still jumping after surgery? The results after facial myospasm decompression surgery are related to age, medical history, physical condition and brain structure, etc. Generally speaking, the older the person is, the longer the medical history and the slower the recovery for those with poorer health. Some symptoms disappear soon after surgery, some disappear in 1-3 months, and some recover more than 6 months or even more than a year before they return to normal. The reason for this is that the degree of damage caused by nerve compression varies, and the postoperative repair time may be longer or shorter. Because the original damaged part of the facial nerve cannot be repaired immediately, it usually takes about 3 months to 3 years to repair. During this process, the facial twitching symptoms will not disappear, but only appear to be lighter and heavier, sometimes not. Due to the complexity of the patient’s brain structure and the difficulty of the surgery, although the surgery has achieved the purpose of decompression, it takes a long time to repair in theory because of the high force of vascular compression and nerve damage. Special reminder: If the patient’s symptoms have not disappeared 2 years after surgery. This two-year period is the observation period of facial muscle facial spasm surgery. If the symptoms of facial muscle spasm have not diminished or disappeared in two years, the surgery can be considered ineffective and further treatment can be considered. Control of facial myospasm attacks during this two-year period can be relieved with carbamazepine medication.
