Efficacy of Sphenopalatine Ganglion Radiofrequency in Refractory Chronic Cluster Headache

摘要

BACKGROUND: In the literature, there are only short series of radiofrequency of the sphenopalatine ganglion (SPG) to treat chronic refractory cluster headache (CCHr) with variable results. Furthermore, there is no consensus on which methodology to use: radiofrequency ablation (RFA) or pulsed radiofrequency (PRF).
