Outcomes

Primary Outcome Measures

Effective rate of Primary Trigeminal Neuralgia treatment
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%.

Secondary Outcome Measures

Patient satisfaction
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
Data regarding patients with a BNI of IV or V who switch to other treatments
Adverse events
Data regarding intraoperative and postoperative adverse events.
The postoperative response rate
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%.

5. Study Description

Brief Summary
The study is designed to compare the effectiveness and safety of high-voltage Pulsed radiofrequency and nerve block for the treatment of primary Trigeminal Neuralgia patients with ineffective conservative treatment and explore better non-surgical treatment methods for Trigeminal Neuralgia patients.
Detailed Description
Trigeminal neuralgia (TN) is a paroxysmal, lightning-like, severe pain in the facial area innervated by trigeminal nerve. Patients who have failed to achieve benefits from drug treatment could try to undergo nerve block, a traditional conservative treatment. Pulsed radiofrequency (PRF) is a noninvasive pain intervention technique for the treatment of TN. However, its treatment effectiveness has rarely been reported and remains controversial among scholars. A recent single-center preliminary clinical study showed that high-voltage PRF had significant effectiveness in the treatment of TN. However, whether high-voltage PRF treatment can become an optional treatment for TN patients who have failed to achieve benefits from drug treatment still needs to be confirmed with standardized clinical studies by utilizing conservative nerve block treatment as a control. The study is designed to compare the effectiveness and safety of high-voltage PRF and nerve block for the treatment of primary TN patients with ineffective conservative treatment and explore better non-surgical treatment methods for TN patients.

Device
Intervention Name(s)
High-voltage pulsed radiofrequency
Intervention Description
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.
Intervention Type
Drug
Intervention Name(s)
Nerve block
Intervention Description
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.
