There are many ways to treat trigeminal neuralgia, and the best results are achieved with microvascular decompression surgery. However, many patients are nervous when they hear that it is open surgery, and they do not know how great the risks are. Here, I would like to briefly explain the risk issue to you: 1. The surgery itself may bring risks. Such as nerve damage and intracranial hemorrhage, this situation has a certain relationship with the experience of the surgeon. As long as the operation is fine and controlled properly, these risks can be reduced to a very low level, and of course, the patient’s own physical condition is also very important. 2, uncertainty of some risks. For example, anesthesia accident, infection and other problems. These situations are unexpected factors that are difficult for doctors to control. Of course, the rate of anesthesia accident is less than one in 10,000, but once it happens, the situation is more serious. 3, the patient’s own risk of concomitant underlying diseases. If the patient also has heart disease, or other diseases such as diabetes. Surgery may cause aggravation of these diseases. Then it is necessary to strictly control these underlying diseases before surgery, and bar the body to adjust to the best condition. In general, we have accumulated a wealth of experience in trigeminal neuralgia surgery, and the risks of the surgery are well controlled.
