Pulsed radiofrequency (PRF) is a minimally invasive procedure used to relieve pain caused by trigeminal neuralgia and selected cases of trigeminal neuropathy.
Unlike conventional radiofrequency thermocoagulation, PRF uses short pulses of electrical current at a lower temperature (42–45°C). Instead of destroying the nerve, it modulates pain transmission while preserving nerve tissue.
Advantages
- Minimally invasive.
- Usually performed under local anesthesia with X-ray guidance.
- Low risk of permanent nerve injury.
- Can be repeated if necessary.
- The procedure takes about 20–30 minutes, and most patients return home the same day.
When Is PRF Considered?
It may be recommended when medication is ineffective or poorly tolerated, or when preserving nerve function is particularly important.
Before treatment, a neurological assessment and a diagnostic nerve block are usually performed.
