PRTG (radiofrequency rhizotomy) is an outpatient procedure performed by placing a needle into the gasserian ganglion, through which an electrical current passes, heating the probe and producing a thermal lesion in the ganglion. Of the percutaneous procedures, it has the lowest reported rate of pain recurrence, with the average patient experiencing 4–5 years of good pain relief. [10]

PRTG, like PBM, is a relatively inexpensive and accessible technique and is less invasive than open surgery, with a lower (long-term) efficacy-to-recurrence ratio. The result is highly dependent on the surgeon’s skill.
