The best treatment for trigeminal neuralgia should be carried out separately for the cause, as follows: 1. Carbamazepine and phenytoin sodium are the drugs of choice for the treatment of trigeminal neuralgia, and with the application of vitamin B12, certain efficacy can be achieved. 2. 1%-2% procaine is applied for blocking anesthesia of the nerve. 3. 95% alcohol is injected accurately into the nerve trunk or the semilunar segment of the trigeminal nerve at the lesion site. By blocking the conduction of the nerve, pain relief can be achieved.4. Radiofrequency controlled temperature thermocoagulation of the ganglion can be performed with good results.5. In case of lesions of the inferior alveolar nerve or infraorbital nerve, the peripheral branch of the trigeminal nerve can be cut and avulsed.
