What department do I go to for trigeminal neuralgia? This depends on the situation. If it is the first attack, medication is still effective for trigeminal neuralgia at this time. You can register with the neurology department for drug relief treatment. However, as the disease progresses, the effect of medication will be reduced, and medication will not be effective in controlling the disease at this time. Therefore, when medication is not effective, patients are advised to choose neurosurgery for diagnosis. The patient’s condition is further determined by the treatment. The best thing is to choose neurosurgery for treatment at the beginning. The pain caused by trigeminal neuralgia can be solved at once through surgical treatment. How to treat trigeminal neuralgia: Microvascular decompression is the best treatment method for trigeminal neuralgia. The operation is to magnify the intracranial nerves and blood vessels under the operation of a high-powered microscope, and then operate, without damaging the nerves and blood vessels, to place the spacer between the blood vessels and nerves, so that the nerves and blood vessels are separated and the blood vessels no longer compress the nerve roots, and the symptoms of trigeminal neuralgia can be solved from the source. The surgery is less invasive, with quick recovery, low complications, and most patients can return to normal within a short time after receiving treatment. It is the best treatment for trigeminal neuralgia.
