Abstract
OBJECTIVE
Ultrasound (US) guided pulsed radiofrequency (PRF) therapy can be used on the greater occipital nerve (GON) in patients with chronic migraine (CM) who are unresponsive to conservative treatments. 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 US-guided GON PRF and the effectiveness of treatment.
PATIENTS AND METHODS
According to the International Classification of Headache Disorders III beta version diagnostic criteria, 25 of 43 patients with CM whom treated with GON PRF were included in the study. 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 PRF 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 postintervention 1st and 3rd month (p < 0.001).
CONCLUSION
In this study, we observed that US-guided GON PRF therapy applied at the proximal (C2) level was a safe and effective treatment option. With GON PRF, we observed a decrease in pain intensity, pain frequency, and duration of episodes, and an improvement in depression symptoms, migraine disability, and sleep disorder scores accompanying chronic migraine.
