Trigeminal neuralgia is a common and frequent disease of facial pain, which mainly refers to the pain caused by the area where the trigeminal nerve is distributed on one side of the face. The trigeminal nerve is divided into three branches in the face: the first branch is the area above our eyebrows; the second branch is the area above the corners of the mouth; and the third branch is usually the area of the lower lip and jaw. These three branches affect each other and interact with each other to trigger pain when induced by certain factors, with the second and third branches being more common. Electric shock-like, pins-and-needles, knife-like or tearing pain Clinically, the common cause of trigeminal neuralgia is the compression of the trigeminal nerve root by blood vessels, which causes pain. The main symptom of the patient is severe unilateral facial pain, which is like electric shock, pinprick, cut or tearing pain. The pain does not usually go beyond the midline. Each attack can last from a few seconds to 1 or 2 minutes and then stop abruptly, with intervals as normal. The condition can gradually worsen and the number of pain attacks become more frequent, even once a few minutes, resulting in more than one day. The pain can be triggered by touching the skin of the patient’s face. In severe cases, patients dare not wash their faces, brush their teeth or even chew, and can only drink a small amount of liquid or semi-liquid food to maintain nutrition, which seriously affects the quality of life. Conservative treatment is not very effective, and surgery is the right treatment route It is well known that patients with trigeminal neuralgia have to suffer unbearable pain at the onset of the disease. Some hospitals take medication, closed therapy, physical therapy and other treatments for patients, which may temporarily relieve pain, but do not achieve long-term results, and patients will still have recurrent pain or even aggravate the condition. So how to relieve trigeminal neuralgia? It is understood that the current use of microvascular decompression to treat trigeminal neuralgia has achieved good results. During the operation, the blood vessels are stripped from the nerve roots behind the patient’s ear and the responsible vessels are isolated with Tefflon spacers. The procedure is effective in resolving pain based on preserving the patient’s normal facial sensation and preserving the anatomical integrity of the trigeminal nerve.
