Objective: Ultrasound-guided pulsed radiofrequency therapy can be used on the greateroccipital nerve (GON) in patients with chronic migraine (CM) who are unresponsive to conservative treatments. In this study, we aimed to demonstrate the change in pain intensity, duration of migraine episodes, frequency of attacks,migraine disability, depression,and sleep disturbance scores before and after treatment in patients with CM who underwent ultrasound-guided GON pulsed radiofrequency and the effectiveness of treatment. Patients and methods:The study included 25 patients who were diagnosed as having CMaccording to the International Classification of Headache Disorders III beta version diagnostic criteria. The Migraine Disability Assessment Scale (MIDAS), Beck Depression Inventory(BDI), Pittsburgh Sleep Quality Index (PSQI),and a visual analog scale (VAS) were used on patients before GON pulsed radiofrequency treatment and at post treatment months 1 and 3. Results:The median duration and number of migraine episodes in the post-interventional 1st month and 3rd month were significantly shorter and fewer compared with the pre intervention period (p\<0.001). In the comparison with the pre intervention values, all of the scoring concepts, namely the MIDAS, VAS, BDI, and PSQI, revealed a significant drop in the post intervention 1st and 3rd month (p\<0.001). Conclusion: In this study, we observed that ultrasound-guided GON pulsed radiofrequency therapy applied at the proximal (C2) level was a safe and effective treatment option.With GON pulsed radiofrequency, we observed a decrease in pain intensity, pain frequency, andduration of episodes, and an improvement in depression symptoms, migraine disability, and sleep disorder scores accompanying chronic migraine.
