title: Pulsed radiofrequency of the second cervical ganglion (C2) for the treatment of cervicogenic headache.
abstract: In this case series report, two patients with cervicogenic headache were selected. After initial positive response to the greater occipital nerve block, pulse radiofrequency (PRF) was performed on the position of the second cervical ganglion (C2). Two patients reported 100% pain relief lasting for 6 months. The lateral puncture is safer and more comfortable than the posterior site. This case study demonstrates the effectiveness of PRF to treat cervicogenic headache originating from the C2 nerve. However, we need to further evaluate the results using more samples.
