Experimental: PRF Group
This group will undergo 42°C high-voltage pulsed radiofrequency treatment.
Device: High-voltage pulsed radiofrequency
The manual PRF mode of the pain treatment generator will be turned on, the upper temperature limit will be set at 42°C, the PRF output voltage will be gradually increased to the highest voltage the patient can tolerate, and the patient will be treated for 360 s. After the treatment, 1.4 ml of a mixture of 0.4 mL of normal saline and 1 mL of 1% plain lidocaine will be injected through the needle of the cannula, and before the needle being removed, 0.5 mL of normal saline will be injected.
Active Comparator: Nerve Block Group
This group will undergo nerve block treatment with steroid and local anesthesia.
Drug: Nerve block
The radiofrequency generator will be set at the sensory stimulating mode, and the lowest frequency of 0.2 V will be used for 360s-sham PRF treatment, after which 1.4 mL of a mixture of 2 mg of dexamethasone sodium phosphate and 1 mL of 1% plain lidocaine will be slowly injected through the radiofrequency treatment cannula needle. Before the needle being removed, 0.5 mL of normal saline will be injected.
- Effective rate of Primary Trigeminal Neuralgia treatment [ Time Frame: 1 year after operation ]The Barrow Neurological Institute (BNI) pain intensity score will be used to assess pain degree. Pain relief degree will be evaluated as "excellent" (BNI pain score I-II), "good" (BNI pain score III), and "poor" (BNI pain score IV-V). The effective rate=excellent and good pain relief (BNI I - III)/total number of cases * 100%.
- Patient satisfaction [ Time Frame: 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after operation ]Patient satisfaction score (PSS) score will be used to evaluate patient satisfaction: 0 point indicates unsatisfactory, while 10 points indicates very satisfactory.
- Dosage of adjuvant antiepileptic drugs [ Time Frame: 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after operation ]
- Data regarding patients with a BNI of IV or V who switch to other treatments [ Time Frame: 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after operation ]
- Adverse events [ Time Frame: 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after opeartion ]Data regarding intraoperative and postoperative adverse events.
