Objectives: The aim of this study was to evaluate the efficacy of greater occipital nerve (GON) block in the treatment of migraine patients.
Methods: This study included 28 patients diagnosed with migraine between 2014 and 2015. The GON block procedure was applied by administering 1.5 ml of 2% lidocaine 2 cm lateral and 2 cm inferior to the external occipital protuberance. The patients were evaluated in respect of VAS scores, attack frequency, attack duration and the need for analgesia before the procedure. These parameters were evaluated again at 1 week, 1 month and 3 months after the procedure.
Results: The mean age of the patients was 42.21±10.13 years. The mean VAS score was 9.28±0.72 before the procedure and 2.96±2.16 at 1 week, 2.60±1.96 at 1 month and 1.75±1.37 at 3 months. The frequency of attacks was 9.42±4.51 before the procedure and, 5.42±3.30 at 1 month and 3.57±3.14 at 3 months.
Conclusion: GON block with 1.5 ml of 2% lidocaine is a safe, simple and effective treatment method for migraine headache.
