“Everyone loves beauty”, but facial muscle spasm makes our face change, no longer as natural as before, facial expression is also limited. Professor Wang of Neurosurgery said, “Facial muscle spasm brings patients not only physical harm, but also mental harm, and the better treatment for facial muscle spasm is minimally invasive surgery – microvascular decompression surgery.” Name: Ly Gender: female Age: 55 years old Condition at admission: The patient had a paroxysmal, involuntary twitching, uncontrollable, short, rapid, lasting a few seconds and then stopping automatically, which appeared in her left upper eye 10 years ago with no obvious cause. At the beginning, the frequency of seizures was not high, several times a day. After the attacks gradually frequent, often twitching, and gradually involved the left corner of the mouth. First the corner of the eye, then the corner of the mouth. 2 years ago in a hospital in Beijing, and oral methylcobalamin, vitamin B, the symptoms did not see significant improvement, then the symptoms gradually aggravated, the frequency of twitching gradually increased, more than ten times a minute, and then in a hospital in Beijing for more than 20 times of closed treatment, the symptoms were slightly relieved, and then aggravated. She came to our outpatient clinic for surgical treatment, and was admitted to the hospital with “facial muscle spasm”, and her general condition was fine. Involuntary twitching of the left corner of the eye and the left corner of the mouth could be seen, occurring at the same time and in a paroxysmal manner. The left nasolabial sulcus was shallower than the right, and the tongue was slightly deviated to the right. Preliminary diagnosis: 1. Facial muscle spasm (left side) Treatment: after admission to the hospital to improve the examination and preoperative preparation, under general anesthesia, the left facial nerve microvascular decompression + lumbar large pool cannulation, the operation went smoothly, the patient did not have any special discomfort during and after the operation, the patient was routinely given postoperative haemostasis, prevention of infection, nutritional support, neurological support and symptomatic supportive treatment, the patient had a good recovery, the patient’s left side of the face corner of the eye and the corner of the mouth after the operation. There was no obvious twitching. The incision healed well. The patient was instructed to go home and recuperate, and the patient and his family were told in detail about the precautions to be taken after discharge, and he was discharged from the hospital. At the time of discharge, the patient was in good condition, with clear speech and no obvious twitching of the corners of the eyes and mouth on the left side of the face. The incision healed well. Discharge diagnosis: facial muscle spasm|(left side) Discharge instructions: 1. Discharge with medication: no 2. Advice to the patient: pay attention to rest, appropriate exercise, reasonable nutrition, enhance physical fitness; 3. Health education: normal diet, avoid spicy; 4. Follow-up time: 1 month. It can be seen in the case that the patient has been suffering from facial muscle spasm for several years, and the effect of many times of medical treatment is not ideal, and then after Prof. Wang’s diagnosis and treatment of microvascular decompression surgery, the recovery effect is good. Microvascular decompression surgery is also a better minimally invasive surgical treatment for facial muscle spasm. Microvascular decompression is internationally recognized as the first choice for treating primary facial muscle spasm. Under the operating microscope, the blood vessels located in the root of the facial nerve that have abnormal routes and cause compression to the facial nerve are removed and fixed so that the blood vessels do not come into contact with the facial nerve, thus relieving the pressure of the blood vessels on the root of the facial nerve, restoring the normal function of the facial nerve, and alleviating the symptoms of facial muscle twitching. The main advantages of microvascular decompression in the treatment of facial muscle spasm are: high cure rate, fast recovery, low recurrence rate, and small trauma to the patient, less bleeding, low complications and other characteristics. Most importantly, microvascular decompression surgery can completely preserve blood vessels, nerve function and so on.
