Summary

Trigeminal neuralgia is one of the most common craniofacial neuralgias and one of the most severe types of facial pain, typically limited to the distribution of the trigeminal nerve. The first-line treatment for trigeminal neuralgia is medical therapy and primarily antiepileptic drugs. Various interventional and surgical methods can be used in patients who do not respond to medical treatment or who cannot tolerate side effects. Pulsed radiofrequency treatment of maxillary and mandibular nerves may provide longer-lasting pain relief in trigeminal neuralgia.This study aimed to investigate the clinical and demographic characteristics affecting treatment success in patients who underwent ultrasound-guided pulsed radiofrequency of the maxillary and/or mandibular nerves for trigeminal neuralgia.

Conditions

  • Trigeminal Neuralgia

Interventions

PROCEDURE

Maxillary nerve and mandibular nerve pulsed radiofrequency

For maxillary nerve pulsed radiofrequency, the lineer transducer is placed distal and parallel to the zygomatic arch, bridging the coronoid and condylar processes and a 22 gauge 6 mm RF cannula was inserted into the target area. With sensory stimulation, patients experienced a distinct sensation in upper jaw, teeth, and palate. Then, PRF treatment was performed at 42 °C for 240 seconds. For mandibular nerve pulsed radiofrequency, the transducer was placed distally and parallel to the zygomatic arch, bridging the coronoid and condylar processes. The pterygopalatine fossa was visualized and the needle was inserted to target area. With sensory stimulation, patients experienced a distinct sensation in the lower jaw and teeth. With motor stimulation, a throwing movement of the jaw was observed with contraction of the masseter and temporal muscles. PRF treatment was performed at 42 °C for 240 s.
