In recent years, facial muscle spasms, a facial nerve disorder, have become frequent in our lives. So what kind of people are prone to get facial muscle spasm? According to relevant data, middle-aged and elderly people over forty years old are the high incidence of facial muscle spasm. As the main cause of facial muscle spasm is that the root of the facial nerve is compressed by blood vessels, and human blood vessels will continue to age with age, coupled with the middle-aged and elderly people are prone to high blood pressure, high blood sugar, high blood cholesterol, and so on, these factors will cause arteriosclerosis, so that the blood vessels are traveling abnormally, which will compress the root of the facial nerve, resulting in facial convulsions. Most patients with facial muscle spasm will experience involuntary throbbing and twitching in the eyelid area, which will slowly develop into other facial muscles. In severe cases, the eyelids become smaller and asymmetrical on both sides, and facial atrophy may also occur, which brings great trouble to the patient’s appearance and normal life, and scientific treatment is needed in order for the patient to get rid of the torment of this disease as soon as possible. Microvascular decompression surgery is a high-powered microscope precise positioning of the surgery, safe and effective, the surgical site in the hairline behind the ear incision size of a coin, under a high-powered microscope to accurately find the compression of the facial nerve blood vessels will be free, through the surgery with special materials Teflon cotton cushion, the compression of the blood vessels from the nerve is completely isolated, so that the blood vessels and nerves are no longer in contact with each other, so as to completely eliminate the cause of the facial spasms! The spasm will stop immediately or gradually, and there will be no damage to the facial nerve. With the improvement of this surgical technique, especially its minimally invasive, high safety, remarkable effect as well as low recurrence rate and low complication rate, etc., in particular, it can completely retain the function of blood vessels and nerves. In addition, microvascular decompression has also been successfully used in the treatment of trigeminal neuralgia and glossopharyngeal neuralgia.
