NCT06366139

Brief Summary

Trigeminal ganglion (TG) radiofrequency thermocoagulation (RFT) and ultrasound (US)-guided maxillary or mandibular (max/mand) pulsed radiofrequency (PRF) are two interventional procedures for the treatment of trigeminal neuralgia (TN). The aim of this study was to compare the efficacy and safety of these two procedures. For this evaluation, the numeric rating scale (NRS) was used to assess pain relief and the Medication Quantification Scale III (MQS III) was used to assess the effectiveness of the interventions on medication consumption. The rates of adverse events related to the interventions were also compared.

Outcome Measures

Primary Outcomes (1)

  • Numerical rating scale (NRS)

    NRS is a scale that can be used measuring pain. Scores range from 0 (no pain) to 10 (the worst pain)

    Change from baseline to 1st and 6th month after treatment

Secondary Outcomes (1)

  • The Medication Quantification Scale III (MQS III)

    Change from baseline 6th month after treatment

Study Arms (2)

radiofrequency thermocoagulation group

ACTIVE COMPARATOR

Trigeminal ganglion radiofrequency thermocoagulation for trigeminal neuralgia

Procedure: Radiofrequency thermocoagulation of the trigeminal ganglion

pulsed radiofrequency group

ACTIVE COMPARATOR

Maxillary mandibular nerve pulsed radiofrequency for trigeminal neuralgia

Procedure: Maxillary/Mandibular nerve pulsed radiofrequency

Interventions

The patient is placed in the supine position and the foramen ovale is identified medial to the coronoid process of the mandible by giving the head a submental oblique position under fluoroscopic guidance. A 20-gauge, 5 mm active type, and 100 mm radiofrequency cannula is inserted 2 cm lateral to the commissura labialis and advanced towards the foramen. After entering the foramen ovale with a lateral fluoroscopic image, the radiofrequency cannula is connected to the radiofrequency generator and sensory and motor stimulations are performed to confirm the target maxillary and mandibular nerves. The radiofrequency lesion is applied at 60°C, 65°C and 70°C for 60-seconds periods. The patient is observed for side effects for 1 hour after the procedure.

radiofrequency thermocoagulation group

The patient is placed in the lateral decubitus position with the affected side up. A 5-12 MHz linear ultrasound probe is placed in the infrazygomatic area above the maxilla at a 45° inclination in both the frontal and horizontal planes. The probe position allows visualization of the pterygopalatine fossa, which is limited to the maxilla anteriorly and the greater wing of the sphenoid posteriorly. Real-time ultrasound guidance allows direct localization of the internal maxillary artery and identification of the needle tip. The radiofrequency cannula was connected to the radiofrequency generator and PRF was applied at 42°C for 240 seconds after confirming the localization of the maxillary and mandibular nerve by obtaining appropriate responses to sensory and motor stimulation.
