Comparison of the Effectiveness of Greater Occipital Nerve (GON) Block and Sphenopalatine Ganglion (SPG) Block in the Treatment of Chronic Migraine.
Healthcare (Basel, Switzerland) | 2026
Observational studySummary
Chronic migraine significantly affects quality of life and can be debilitating. This study compared the effectiveness of greater occipital nerve (GON) block and sphenopalatine ganglion (SPG) block. It involved 50 patients diagnosed with chronic migraine. Patients received either a GON block or an SPG block. Researchers evaluated monthly migraine days, pain intensity, and migraine-related disability before and after treatment. Both treatment methods showed significant reductions in these areas. However, patients receiving GON block experienced a greater reduction in monthly migraine days. The study suggests that both GON and SPG blocks could be effective adjuncts to standard treatment. GON block may offer superior benefits regarding migraine frequency reduction. Despite positive results, further prospective studies are necessary to confirm these findings. This research adds to the understanding of non-pharmacological options for chronic migraine management and treatment. Clinical relevance: This study indicates that GON block may provide more effective migraine relief than SPG block.
Key Learning Points
- Chronic migraine can greatly impact daily life and may lead to significant disability.
- Both greater occipital nerve block and sphenopalatine ganglion block can effectively reduce migraine symptoms.
- Patients receiving greater occipital nerve block reported a greater decrease in the number of migraine days compared to those receiving sphenopalatine ganglion block.
- These treatments can serve as helpful additions to standard migraine management strategies.
- Further research is needed to validate these findings and enhance chronic migraine treatment options.
