Comparing Unilateral and Bilateral Proximal GONPRF in Migraine Treatment
Sponsor: Ankara City Hospital Bilkent
Summary
This study is designed to compare the clinical effectiveness of unilateral and bilateral Greater Occipital Nerve Pulsed Radiofrequency (GON-PRF) treatment at the C2 level in patients with migraine. The procedure will be guided by ultrasound and will focus on evaluating how each technique affects migraine symptoms. The main goal of this study is to assess the impact of both unilateral and bilateral GON-PRF treatments on migraine relief. Additionally, the secondary objectives of this study include evaluating the effects of these treatments on migraine-related disability and comparing any potential side effects or complications that may occur during the treatments. This research will help us understand which technique may be more effective and provide more information on the safety of these treatments.

Interventions
Greater Occipital Nerve Pulsed Radiofrequency (Unilateral)
Greater Occipital Nerve (GON) Pulsed Radiofrequency (PRF) treatment is performed under sterile conditions in the operating room. The patient is positioned in the prone position with neck flexion. Under ultrasound guidance at the proximal (C2) level, the needle is carefully placed near the GON, targeting the space between the Obliquus Capitis Inferior (OCI) muscle and C2's bifid spinous process. After proper sterilization, a linear ultrasound probe is used transversely over the occipital protuberance to locate the C1 and C2 vertebrae. Once identified, the RF needle and electrode are inserted laterally to medially using in-plane technique. A sensory stimulation test is done, and the PRF therapy is applied at a 45V setting, 5 Hz, and 5 ms pulse width for 360 seconds, with a maximum temperature of 42°C. No drug injections are administered during the procedure. Post-procedure, the patient is monitored for at least 1 hour before discharge after a general and neurological evaluation.
