Randomized Controlled Trial Comparative Study
Comparison of High-voltage- with Standard-voltage Pulsed Radiofrequency of Gasserian Ganglion in the Treatment of Idiopathic Trigeminal Neuralgia.
Although pulsed radiofrequency treatment (PRFT) has been used to treat trigeminal neuralgia (TN) safely, satisfactory improvement is lacking. Recently, much attention has been paid to the PRFT dose and intra-operative parameters. It has been reported that high-voltage PRFT could significantly reduce discogenic pain. ⋯ The effective rate in the standard-voltage group decreased to 19% at 1-year postoperative, while in the high-voltage group remained at 69% (P = 0.000). No significant side effects were detected in both groups. In conclusion, CT-guided high-voltage PRFT is an effective and safe interventional therapeutic choice for idiopathic TN patients.

Randomized Controlled Trial Comparative Study
Efficacy of the Greater Occipital Nerve Block for Cervicogenic Headache: Comparing Classical and Subcompartmental Techniques.
The aim of the study was to compare the efficacy of the greater occipital nerve (GON) block using the classical technique and different volumes of injectate with the subcompartmental technique for the treatment of cervicogenic headache (CH). ⋯ While the classical technique for GON block resulted in only 2 weeks of analgesia, the subcompartmental technique resulted in at least 24 weeks of analgesia, being 5 mL volume sufficient for the performance of the block under fluoroscopy.
