Trigeminal neuralgia (TN) is a neuropathic pain disorder that affects the trigeminal nerve distribution area. Pharmacological therapy has remained the first-line treatment for TN. If pharmacological intervention is not effective, surgical treatments including radiosurgery (mainly gamma knife therapy), radiofrequency (RF) of the Gasserian ganglion, and microvascular decompression have been utilized. ⋯ The pain relief rate in PRF-treated patients was significantly lower compared to CRF-treated patients. Furthermore, recurring pain was more commonly observed in PRF-treated patients. Therefore, CRF may be the preferred treatment option for TN, whereas treatment with PRF requires further study.
