”There is no painful suffering, how can this tell me to stop?” The left side of Cao’s face twitches over and over again, the frequency is getting faster and longer, “two years, tired of running, can’t run, which makes me upset, how can you tell me to stop?” Let Lao Cao suffer from this “can not stop the marathon” is actually “facial muscle spasm”. As the name implies, “facial muscle spasm” is an involuntary paroxysmal, spasmodic twitching of one side of the facial muscles. This condition first affects the muscles around the eyes (orbicularis oculi), and then gradually affects other muscles on the same side of the face. Therefore, patients often start with “eyelid fluttering”, which eventually leads to a crooked mouth. Of course, this condition does not persist, but occurs intermittently, but at increasingly shorter intervals. In the early stages of the disease, the interval can be days or even months, but in the later stages, the interval can be as short as minutes or even seconds. Emotional stress, nervousness and fatigue can add to the problem. “Facial spasm” is a functional disease that does not affect food, drink, or life expectancy, and is the same as normal during the interval between attacks. But all patients say, “This has seriously affected my quality of life, and now there is no way to communicate with others normally.” Moreover, in the long run, the patients would develop a light paralysis of the face. To date, we do not fully understand the cause of “facial spasm”. However, clinical experience shows that more than 67% of patients have vascular compression of the facial nerve. Therefore, most scholars around the world agree that the cause of facial spasm is related to vascular compression. In other words, the facial nerve is compressed by blood vessels, resulting in localized demyelination and other changes that cause abnormal excitation of the nerve nuclei. Translated, this means that the nerve is short-circuited! Under this abnormal, high-frequency nerve signal stimulation, the facial muscles want to take a stimulant like involuntary, frequent twitching.” Muscles in this high-intensity “training”, “master” has been tired of running, the biggest desire is “stop!” There are many ways to “stop”, such as acupuncture, massage, physical therapy, Botox injections, etc. Although the short-term effect can be, but it is difficult to maintain long-term. With the development of minimally invasive technology, surgery is the only hope. Microvascular decompression is a safe and less invasive treatment method, and it can protect the blood vessels and nerves intact. The main character of this story, Lao Cao, was cured by this treatment method. The pre-surgical brain MRI of Cao clearly showed the cause of the disease – the left facial nerve was compressed by a blood vessel, and it was quite serious. Although the anterior inferior cerebellar artery was tightly squeezing the facial nerve, it was only the “intermediary”, and the more powerful impact came from the basilar artery. The purpose of the surgery was to completely separate these two vessels from the facial nerve. However, what was seen during the surgery was a mass of blood vessels wrapped around the facial nerve. The delicate “piecing together” operation determines the safety of the surgery, while the accurate positioning of the responsible vessels determines the effectiveness of the surgery. After carefully separating the mass of vessels wrapped around the facial nerve, the responsible vessel was clearly identified at the root of the facial nerve at the brainstem, as predicted before surgery. Then, the basilar artery and the anterior inferior cerebellar artery were cushioned with Teflon pads, respectively, to complete the complete decompression of the facial nerve. The left side of Cao’s face stopped “running”.
