Viral trigeminal neuralgia can be treated by oral medication, closed treatment, radiofrequency ablation and surgery as prescribed by the doctor. 1. Oral medication: For virus-infected trigeminal neuralgia, patients can take oral medication such as carbamazepine tablets and gabapentin capsules as prescribed by the doctor for treating neuralgia, and at the same time, they can be treated with antiviral medication such as acyclovir tablets or ganciclovir dispersible tablets. 2. Closure therapy: for patients who have no effect of oral medication, anhydrous ethanol or glycerin can be tried to close the trigeminal nerve branches, destroying the sensory nerve cells, which can achieve the effect of pain relief, and the adverse reaction is the loss of facial sensation in the injection area. 3. Radiofrequency ablation: It is to reduce the trigeminal nerve pain through the damage of the semilunar ganglion, which may have some complications, such as the patient’s facial nerve injury. 4. Surgery: For patients with poor results of the above treatments, they can consider trigeminal nerve root microvascular decompression surgery under the advice of the doctor for treatment. Patients with viral infection of trigeminal neuralgia should go to the hospital in time to avoid delaying the condition and causing adverse consequences.
