For patients with primary trigeminal neuralgia, trigeminal neuralgia can be treated with medications such as carbamazepine, phenytoin sodium, gabapentin, etc. However, there are many adverse effects, such as dizziness and nausea, which can disappear after stopping medication. However, it must be pointed out that there is no drug treatment that can completely cure trigeminal neuralgia, and the pain control effect of most patients will gradually decline after long-term medication, and drug intolerance will occur, so patients diagnosed with primary trigeminal neuralgia should consider surgical treatment. The most popular surgical procedure is microvascular decompression. It can effectively treat the patient’s disease. Surgical treatment of trigeminal neuralgia is more advantageous: Microvascular decompression is a treatment method that targets the cause of trigeminal neuralgia and preserves the anatomical integrity of the trigeminal nerve, so the normal nerve function of the trigeminal nerve can be preserved. Because microvascular decompression has the advantages of obvious pain relief, non-destructive, little side injury, and very low recurrence rate, it is currently the safest and most effective method internationally recognized for the treatment of trigeminal neuralgia. Under general anesthesia, a 4-6 cm longitudinal incision is made behind the affected ear and in the hairline, and a hole is made in the skull with a diameter of about 2 cm to access the pontocerebellar angle under the microscope. Once the responsible vessels are isolated, the source of irritation disappears, and the hyperexcitability of the trigeminal nucleus disappears and returns to normal. In the vast majority of patients, pain disappears immediately after surgery and normal facial sensation and function are preserved without affecting the quality of life. Are there complications of surgery? Except for patients who cannot tolerate surgery, all other patients with trigeminal neuralgia are suitable for microvascular decompression surgery. The most common complications of surgery include hearing loss and facial sensory loss, but with the improvement of microsurgery, the incidence of these complications is very low in large neurosurgical medical institutions, and most of the symptoms of brain nerve injury are mild and can be recovered gradually. There is no need to worry too much about surgical complications.
