Preoperative preparation for trigeminal neuralgia Trigeminal neuralgia is often overlooked by patients in its early stages and is easily confused with general pain, resulting in delayed treatment of the condition. So, what kind of tests are usually done for trigeminal neuralgia? Cranial CT and MRI examinations These two examinations can detect the presence of cranial tumors and inflammation in patients with trigeminal neuralgia. Inflammation is a common cause of secondary trigeminal neuralgia. Tumors of the pontocerebellar horn account for the majority of tumors, with cholestatic tumors taking the first place, and inflammation refers to arachnoiditis of the pontocerebellar horn. Magnetic resonance angiography (MRA) examination Magnetic resonance angiography has become an effective examination method for the evaluation of vascular diseases. When examining trigeminal neuralgia, the relationship between trigeminal neuralgia and trigeminal nerve vascular compression can be analyzed in order to develop a reasonable treatment plan, perform microvascular decompression more effectively, and further improve the cure rate of patients with this type of trigeminal neuralgia. Blood glucose or glucose tolerance test Patients with trigeminal neuralgia who also have diabetes mellitus should also have a blood glucose or glucose tolerance test to rule out diabetic neuropathy in trigeminal neuralgia patients. Cardiopulmonary function tests Especially in elderly patients, it is important to know the function of the patient’s vital organs to ensure the safety of the perioperative period. Blood tests such as routine blood tests, blood biochemistry, coagulation function, etc. Elderly patients must stop taking anticoagulant drugs such as aspirin, Poliovel, Warfarin to ensure the coagulation status, preferably for more than five days. After the early symptoms of trigeminal neuralgia appear, patients must go to a professional hospital for regular treatment of trigeminal neuralgia and ask experts to do detailed diagnosis and treatment for you. Many patients always hope to have surgery immediately after hospitalization, but in fact this is not necessarily a good thing for patients. This is because it takes time to perfect the preoperative examination, adjust the patient to the best condition, the doctor’s comprehensive grasp of the condition, the anesthesiologist’s understanding of the surgery, etc. Most importantly, there must be time to allow the surgeon to look at the patient’s CT and MRI films a few more times. Please remember, the patient, you came to the hospital for treatment, not to complete the task of surgery!
