Most people are not unfamiliar when it comes to facial spasm, because there are many people around us who suffer from this disease, and every time we meet, we will see each other either squeezing their eyebrows or slanting the corners of their mouths. If the patient has this condition, it means that the condition has developed seriously. Facial muscle spasm usually starts with eyelid fluttering, but many people tend to ignore this detail and do not take the initiative to seek medical attention until multiple parts of the face twitch or the entire face twitches. According to the clinical treatment results, surgery is a better way to treat facial muscle spasm. Microvascular decompression is a standard procedure recognized by the medical community for the treatment of facial muscle spasm, relieving facial muscle spasm while not damaging facial nerve function. So, is it appropriate to do the surgery for patients with facial muscle spasm at the age of 75? For patients who have had the onset of the disease for more than half a year, who are seriously affected by normal life, who have poor results of conservative treatment, who do not have serious organic lesions of the heart, lungs, liver and kidneys, etc., and who can tolerate general anesthesia, surgical treatment can be considered. Microvascular decompression surgery is widely performed clinically. Under general anesthesia, a straight incision of 3~5cm is made longitudinally behind the affected ear and within the hairline, and after cutting the scalp, a bone window of about one coin in diameter is opened in the skull. Then, after entering the pontocerebellar area under the microscope, the facial nerve travel area is carefully explored, the blood vessels compressing the nerve are precisely found, all the blood vessels compressing the facial nerve are pushed aside, and the nerve is cushioned from the blood vessels with Tefflon spacers and glued. The postoperative recovery is fast and does not leave scars.
