Brief Summary

Chronic migraine (CM) is related to headache-related disability and reduced quality of life. Therefore, patients with CM require preventive treatment. The aim of this double-blind, comparative-effectiveness study was to compare ultrasound-guided great occipital nerve (GON) block and pulsed radiofrequency (PRF) application in CM patients. The study consisted of 2 groups: GON block (group GONB) and GON block + pulsed RF (group GONB+PRF). Each group had 16 patients. Ultrasound-guided GONB was performed to locate the nerve more accurately. With 0.5 Hz sensorial stimulation, a 5-cm-long radiofrequency needle was advanced under ultrasound guidance in both groups. GON block was performed in all patients by administering 5mg bupivacaine through a PRF needle. After the GON block, the PRF neuromodulation was applied at 42 degrees for 4 minutes in the GONB-PRF group. In the GONB group, no pulse was given. The patients were examined for follow-ups at the 1st, 2nd, 3rd, and 6th months after the procedure. The severity and the number of migraine attacks, and the number of analgesic drugs were noted.

Interventions

With 0.5 Hz sensorial stimulation, a 5-cm-long radiofrequency needle with a 0.5 cm active tip was advanced under ultrasound guidance in both pulsed PRF and nerve block groups. USG probe was located to medial one-third of the superior nuchal line between the occipital tubercle and mastoid process under sterile conditions. Finally, the placement of the needle was verified by Doppler imaging of the occipital artery. A 0.3-0.5 Hz sensory stimulus was given with the RF device, and the paresthesia sensation in the patient's occipital nerve dermatome was questioned, and location verification was performed. Then, GON block was performed in all patients by administering 5mg bupivacaine through a PRF needle. After the GON block, the PRF neuromodulation was applied at 42 degrees for 4 minutes in the GONB-PRF group. In the GONB group, the PRF generator was set for 4 minutes, and the time was waited, but no pulse was given.
