The early stage of trigeminal neuralgia caused by fire is mainly treated with medication, and the first choice of medication is carbamazepine. Carbamazepine can make patients with trigeminal neuralgia more than 80% effective, but some patients may experience serious adverse reactions during the course of taking the drug. Therefore, phenytoin sodium may be considered for patients with severe adverse reactions. When the effect is not well controlled, the combination of Chinese medicinal preparation heliotrope can be used for treatment, which is also helpful for controlling the symptoms. When medication is ineffective, trigeminal neuralgia microvascular decompression can be considered, and this surgical procedure can provide complete relief of trigeminal neuralgia.
