Proximal and Distal Approaches to Ultrasound-guided Greater Occipital Nerve Block for Chronic Migraine: A Systematic Review and Meta-analysis of Efficacy and Safety (P1-15.010)

Key Points

• The aim is to assess the efficacy and safety of ultrasound-guided greater occipital nerve block for chronic migraines, focusing on different injection techniques.
• Conducted a systematic review and meta-analysis.
• Compared outcomes between proximal and distal injection techniques.
• Evaluated both efficacy and safety of the US-GONB procedure.
• Identified effectiveness of both proximal and distal approaches in reducing migraine frequency.
• Showed a significant improvement in patient-reported outcomes after US-GONB.
• No major safety concerns reported for either injection approach.
